House of Traditional Nias "Omo Hada",,

Preservation of Omo Hada Site

I. Background.
North Sumatera Heritage is one of NGO in North Sumatra that have concern on saving the cultural and natural heritage. It was founded at the beginning by NGO’s activists, historian, and antropologist from University of North Sumatra on 10 November 1998 in Medan, North Sumatera Province. One of the reasons in forming the institution is based on the reality in connection between heritage and development . There is unjustice condition when the development process tend to alienate the existence of natural and cultural heritage. So, it is important to give serious attention and advocacy the right of people in relation with their cultural and natural heritage..
The main issue that will be run by North Sumatra Heritage (NSH) is saving the natural and cultural heritage especially in North Sumatra region. For cultural heritage NSH’s concern on tangible and intangible heritage. Both of the type of heritage have important role in forming a culture concept in the community. For natural heritage our concern is how to preserve and save the environment through cultural approach. So, both of natural and cultural heritage are very important to keep and saved
North Sumatra Province is the one of province in Indonesia. This province is located in the West of Indonesia and covered by two coastal area, West Coast and East Coast; and also surrounding by many Palm Plantation Company from colonial era. In the last, when colonial era, North Sumatra also known as Eastern Sumatra. Many people from the different ethnic live in this region. They consist of Batak, Malay, Java, China, Nias, Minangkabau, Aceh, India, etc. All of them have important role in forming the culture in North Sumatra. There are more than 12 million peoples that live in this province that spread in 27 regency. Each of regency have an unique cultural and natural heritage.
Mostly the cultural heritage in North Sumatra influenced by colonial era and amalgamation process. Some of the cultural heritage is come from dutch and british colonial era, and amalgamation between the Malay ethnic with another ethnic like: Cina, Batak, Java, Aceh, Minagkabau, India /Tamil.
Medan is the Capital City of North Sumatra Province with total population around 2 million peoples. Medan is the third biggest city of Indonesia after Jakarta and Surabaya. Although many ethnic live in this town, but there is no dominant culture. Each of ethnic can live side by side with peaceful. This town has shown the symbol of multiculturalism. In this town, we also can find the heritage building from colonial era but not much. Most of the old building has been changed by the modern building, like mall and plaza. Although there is regulation that protect the old building but caused by economic factor many old building from colonial era has been lost.
Although our area of work cover in North Sumatra, but in this paper we will exposed our activities in Nias Island; one of regency in North Sumatra Province that have many rich cultural and natural heritage.

II. Nias Island: One of Cultural Heritage in North Sumatra
Nias Island is the part of North Sumatra Province that have many rich of cultural and natural heritage. Location of this regency is separated by the sea from other region in North Sumatra Province . It was located between 0 12’ – 1 32’ NL and 97 – 98’ EL. Geographically, Nias has boundary

[1]:
- In the North border on Pulau Banyak and Aceh Province
- In the South border on Southern Nias
- In the East border on Pulau Mursala, Middle Tapanuli
- In the West border on Indonesia Ocean
Base on the data from Statistical Bureaue 2006, total population in the whole of Nias are 729.966 people that separate in the area as wide as 532.050 Km2

 

[2]. It has been cover both of Main Nias with capital city Gunung Sitoli and Southern Nias with capital city Teluk Dalam. In the last ,Southern Nias still part of Nias regency or Main Nias. But since 2003 Southern Nias has become an otonomous region

[3]. When the big earthquake hit Nias on 28 March 2005 with the richter scale 8.7, many facilities and infrastructure like the building, bridge, road get serious damaged and could not be function. But we stilll find “Omo Hada”, the Traditional House of Nias people athat still stand up with sturdiness and become a silent witness when the big earthquake hit Nias.

III. Omo Hada: Traditional House of Nias People
There are many term of traditional house of Nias people. Some people was called as Omo Hada[4]; Omo Sebua[5] and Omo Nifolasara[6].. According to the type, Omo Hada can be divide in three model: oval, square and combine between square and oval size. In Southern Nias the type of Omo Hada is in Square size; in Gunung Sitoli is oval size. Combining of the oval and square size can be found in the North of Nias.
The significant meaning of Omo Hada is a symbol of properties from the owner and his power to the villagers. Omo Hada also become represent of cosmology of Nias people in relation with their live and environment. Nias people believe if the world has divide in three level: up world, middle world and low world. It can be seen from the structure of Omo Hada.
As traditional house, Omo Hada become a unique building because didn’t use nail in the structure and all of material consist of the hard wood. This is one of the reason why Omo Hada still hold out from earthquake disaster. It has been evident if Omo Hada still stand up and strong enough although hit by the big earthquake. The existence and sturdiness of Omo Hada has been inspired of many people to take lesson learnt from this building.
There is no much anymore traditional house “Omo Hada” in Nias Island. There are around 4 Omo Hada with the big size that still exist in Southern Nias. One of the house is located at Hilinawalo Mazingo village, Teluk Dalam subdistrict, Southern Nias. Total population in Hilinawalo Mazingo village are 2435 equal with 480 head of families, consist of 1146 females and 1249 males. Population is dominated by young man and children. Mostly people get married at twenty years old and seventeen years old.. many teenagers do not stay in the village and usually go to the town for study or work in plantation company. Hilinawalo Mazingo village the one of adat village that still exist in Southern Nias. As a custom village, usually, the village still use the custom ways in their live and Omo Hada site has become a center of custom activity in the village.

IV. Preservation Activities : Experience from North Sumatra Heritage
Some effort and activities that has been done by North Sumatra Heritage in relation with preservation of Omo Hada at Hilinawalo Mazingo village are below:

1. Technical Studies
Technical studies is the first step of our activity to preserve Omo Hada. There are two activities that has been done in this stage. First, measurement the wide of the village and height the village from the sea level. Then, we also documented and record all of houses in the village not only traditional houses but also Malay houses [7]. Second, run measuring the detail of Omo Hada that include the upper part, lower part and middle part. Out put of the technical studies is a Map about Omo Hada site and sketch of house’s compound in the village. Meanwhile the aim of this activity is to get detail information about Omo Hada site.

2. Mapping and Inventory
The aim of mapping activity is to get description about the village and its environment.and the result of mapping is a simple map about area that mapped with the villagers. Some activity that will be done in mapping activity consist of : walk around the village, inventorying the ornament in Omo hada, interior and exterior side including the meaning of symbol in the ornament.; identifying and inventorying the kind of trees or native wood ion the village forest. During run the mapping, we still can find the native “hard” wood “Afoa tree” in the village forest .
We also found correlation between symbol of ornament in the interior and exteri or of ornament at Omo Hada with the plant that growth around the village forest. The tree could found in the village like Afoa tree (red meranti). This is one of the material wood that used for Omo Hada.
Inventory activity conducted by noting some tools and ornament also interviewing the Chiefs of Omo hada, local leader, informal and formal leader in the village about the history and other relevant information.
Both of Technical Studies and Mapping/Inventory above are possible to be done through support from World Monument Fund. This is the part of emergency stabilisastion of Omo Hada before restoration. Output of the activity is provide the data and information about detail Omo Hada site, the village profile in social, cultural and natural aspect.


3. Carpentry Course
The sturdiness of Omo Hada, has been inspired any parties to take lesson from the building. All of material of the building consist of the hardwood and stand on the stone as foundation. It was evidence if the building able to endure the big earthquake that hit Nias in several times. So it is important to inheritance the knowledge and experience of Nias people in building the houses from wood material. Transfer of knowledge about the carpentry skill from the older generation to the younger generation of Nias is very important to be done, if not the local knowledge will be lost. This is the main reason why the carpentry course training is very important to be done in Nias after earthquake. The course training is lead by the master of carpenter from the village and followed by the youth generation of Nias people. There are 20 young generation of Nias that participate in this training. At the end of Carpentry Course, participant of training succed to create the miniatur and replica of Omo Hada site .The carpentry course has been done fore one month since November/December 2005.


4. Seedling of Afoa Trees
Recently, Nias people didn’t interest to build again the traditional house because the wood material is difficult to find. Although in some area we still found the wood but not much. So, this is important to save and plant the native hardwood, seed of Afoa trees in Nias, especially after earthquake. This is our main reason to run seedling Afoa wood.
Seedling activity was done during May and July 2006 along with the people through planting 1200 afoa trees (the red meranti) on the 5 villages. Planting of Afoa trees also done at the school through involving the student from the high school and run the workshop about the urgent of seedling activity. The workshop was attended by the elder, teacher and the student. Through the seedling activity and the workshop we want to raise awareness of the people about the urgent of natural heritage that they own. Both of Seedling of Afoa tree and Carpentry Course were possible to be implemented after there is collaboration and supporting from Turnstone Tsunami Fund.

5. Restoration
On 2007, we start to run the restoration work of Omo Hada at Hilinawalo Mazingo village. After run the assessment, there are some part of Omo Hada need to be repaired : Roof, Floor, Wall and Supporting beam of the roof and Sikholi.
NSH run the assesment in preparing the restoration since January 2007. During in the assesment, NSH run the inventories about the detail of part of Omo Hada that must be repaired, wood material that will be used and carpenter that will involve in the restoration. All process of the restoration work was started with any step below :

a. Assesment
Assesment has been done since Januari 2007. The aim of this activity is to get detail information about anything that have connected with preparation of Omo Hada’s restoration. Based on the assesment known if some of part of Omo Hada need serious attention like : the wall foundation (sikholi), the wall (laso), son of the wall (ono laso), roof on the top, right and left side; supporting beam of roof and floor on the kitchen room.



b. Measuring and Providing the Wood Material
On May 2007 the restoration work of Omo Hada was started with run the measuring the part of Omo Hada and other material that will be used on the restoration. Before starting the work of restoration, the carpenters and the Chiefs of Omo Hada run the Adat ceremony and Praying together .

c. Adat ceremony
Slaughtering the pig was done as indicate the important part of adat ceremony. After that, people will run feast together. The feast ceremony attended by head of the church, elder in the village, carpenter, and represent from other village. This ceremony is very important, first to inform to the public if there is working in the village; second, praying to the God for safety during in the work; third, as a symbol of prestige especially for the owner.

d. Praying together
The restoration work run after the adat ceremony done. The head of carpenter ask permission to the Chiefs of Omo Hada to pray together before start the work. The aim of activity is to get protect and safety from the God during run the restoration work.
The restoration work lead by the master carpenter from the village and assist by some carpenters in the village. Some parts of Omo Hada that will be repaired.: SIkholi (wall foundation) on the right and left side; Wall on the right and left side; Floor on the kitchen room; Roof on the right and the left side; Supporting Beam of the roof.
All of the restoration work use the expert from local carpenter in the village and involving the Chief of Omo Hada site. We realize if the Chiefs and people in the village still have knowledge and experience in building their traditional house

6. Current Condition of Omo Hada
Preservation activities that we have done in Nias has give us many experience in relation with saving and protecting the Omo Hada site and Hilinawalo Mazingo village in Southern Nias regency. Although we have work in Nias before earthquake, and become more intensive after earthquake. But it can not be done if there is no supporting from any parties, mainly from people in the site location.
There are many changing in Nias Island since many international aid agency develop this region. The changing process can be seen through building many facilities and infrastructure around in Southern Nias and Main Nias. The reconstruction and rehabilition process still going on and will be finishing on April 2009. Mostly the process of rehabilitation and reconstruction, especially building the houses still use the concrete material, meanwhile Nias Island is very sensitive with the earthquake. So, it would be wise if the rehabilitation and reconstruction process use the wood material. Because this material is very adaptable and more resist with the earthquake.
We should recognize that condition of Omo Hada site after restoration become more stronger and sturdiness then before. It can be seen when the carpenter still run the thatching process on the upstair side of Omo Hada at the same time the big earthquake hit Bengkulu also Nias with magnitude 7.9 on the richter scale. It was amazing, the carpenter that still can work on the roof but they didn’t feel any vibration caused by the earthquake.
Because the owner still live in the house, they should be take care and protect this house from any damage threatment, especially from the water threatment when they cook at the kitchen room. Beside the water, insect infestation to the wood also become serious threatment.
The restoration work process that has been done was recovery the important part of Omo Hada, like Sikholi (the wall foundation on the left, the right and the backside of Omo Hada), roof, floor and some of the wall and many supporting beam on the upstair side of Omo Hada.

7. Closing: Message for the 1st Conference of Asian National Trust
It was great that the 1st Conference of Asian National Trust can be implemented in Seoul since 22 – 23 May 2008. This is the important point for Heritage Organization in Asia to revive from the sleep. Since long time, Asian countries are very famous with the cultural heritage that have contributed to form the civilization in the world. There are many cultural heritage that spread around in Asian Countries. But the most important thing is all of heritage have important role in forming and enrich the cultural heritage in the world.
Through this conference, we hope there is understanding about the urgent of networking and partnership between heritage organization in Asian countries. We also hope the conference able to build alliance and solidarity between heritage organization in Asian countries. Sharing information and exchange the experience are very important between the heritage organization in Asian countries.
There is condition in developing countries that cultural heritage development. tend to marginalized from development as generally. Development always put economic approach as priority and didn’t give serious attention for the cultural aspect. Many old building has been changed by the new modern building. It was become worst when the policy and regulation tend to oriented and give opportunity for economic oriented.
The first conference of Asian National Trust in Seoul Korea have important role to put a basic platform for heritage organization in Asian countries to give respons any changing in the world especially that have relation with cultural heritage. Asian countries are a part of community in the world that have contribute in forming the civilization in the world.
Through these conference we hope there is a new paradigm that will be born regarding with developing of cultural and natural heritage in Asian Countries. We also hope there is a commitment and opportunity from all participant of the conference to develop a collaboration between heritage organization in preservation, conservation, training and education. It would be possible if there is a strong networking between heritage organizatioin in Asian Countries. Hopefuly.

Rumah Adat Nias "Omo hada", tahan Gempa!

Omo Hada tidak rubuh saat gempa besar menghempaskan Nias dua tahun lalu. Rumah tradisional terbuat dari kayu tanpa paku ini hanya bergeser sedikit, padahal usianya sudah mencapai ratusan tahun. Anehnya, rumah-rumah batu bersemen dengan rancangan masa kini malah banyak yang hancur.

RUMAH-rumah kayu beratap oval masih berdiri kokoh di desa tradisional Tumori, Gunungsitoli. Beberapa rumah sudah menggunakan pernis serta bercat masa kini meskipun bentuk aslinya tidak berubah, kecuali pintu masuk yang dialihkan dari samping melalui tangga kayu. “Aslinya, pintu masuk omo nhada dari bawah kolong, tapi sekarang hampir semua dari samping supaya tamu mudah untuk masuk ke dalam,” kata Ya’aro Zebua, 72 tahun.

Ya’aro Zebua adalah arsitek atau tukang yang memiliki keahlian membangun rumah adat Nias (omo hada) di Desa Tumori. Dia mendapatkan keahlian itu secara turun-temurun. “Desa ini sudah berusia lebih 200 tahun,” katanya, “semua rumah di sini dibangun oleh kakek dan orangtua saya.”

Omo hada asli tidak menggunakan paku, melainkan pena dan pasak kayu, sebagaimana rumah knock down atau bongkar pasang. Bahan kayu yang digunakan merupakan pilihan, diperoleh dari hutan-hutan di Nias. “Sekarang susah mencari kayu-kayu pilihan untuk membangun rumah adat, sudah habis dari hutan,” ungkap Zebua. Syukurlah, rumbia untuk atap rumah masih dapat dibuat dari nyiur sehingga bumbungannya tetap tampak unik. Bumbungan kelihatan jadi semakin unik dengan adanya satu hingga dua tuwu zago, yaitu jendela di bagian atap sebagai ventilasi dan sumber cahaya bagi rumah. Tuwu zago ini terdapat di atap bagian depan dan belakang bumbungan.

Tiang Kayu dan Simbol Omo Hada

Setiap omo hada memiliki enam tiang utama yang menyangga seluruh bangunan. Empat tiang tampak di ruang tengah rumah, sedang dua tiang lagi tertutup oleh papan dinding kamar utama. Dua tiang di tengah rumah itu disebut simalambuo berupa kayu bulat yang menjulang dari dasar hingga ke puncak rumah. Dua tiang lagi adalah manaba berasal dari pohon berkayu keras dipahat empatsegi, demikian pula dua tiang yang berada di dalam kamar utama. Setiap tiang mempunyai lebar dan panjang tertentu satu dengan lainnya. “Semakin lebar jarak antara tiang simalambuo dengan tiang manaba maka semakin berpengaruhlah si pemilik rumah,” ungkap Ya’aro Zebua lagi.

Rumah-rumah adat di Nias juga tidak memiliki jendela. Sekelilingnya hanya diberi teralis kayu tanpa dinding sehingga setiap orang di luar rumah dapat mengetahui siapa yang berada di dalamnya. Menurut Zebua, desain ini menandakan orang Nias bersikap terbuka, jadi siapapun di desa dapat mengetahui acara-acara di dalam rumah, terutama yang berkaitan dengan adat dan masalah masyarakat setempat. Biasanya pemilik rumah bersama ketua adat duduk di bangku memanjang di atas lantai yang lebih tinggi—disebut sanuhe—sambil bersandar ke kayu-kayu teralis, sedangkan yang lainnya duduk di lantai lebih rendah atau disebut sanari. Setiap acara adat akan berlangsung di dalam rumah, terlebih dulu seisi kampung diundang dengan membunyikan faritia (gong) yang tergantung di tengah rumah. Faritia di rumah adat Nias Selatan dilengkapi oleh fondrahi, yaitu tambur besar sebagaimana terlihat di omo sebua—rumah besar untuk raja dan bangsawan—di Desa Bawomatoluo, Teluk Dalam.

Segi artistik juga menjadi perhatian dalam pembangunan omo hada. Banyak kayu-kayu berukir menghias interior dan eksterior rumah. Ini menandakan orang Nias mempunyai rasa seni tinggi.

Kayu Elastis Menahan Gempa

Mengapa omo hada tak rubuh saat gempa? Ya’aro Zebua mengatakan kayu-kayu yang digunakan untuk rumah mereka bersifat elastis. " Jadi saat gempa rumah pun 'main' [ikut bergerak] sesuai guncangan bumi.” Tetapi, diakuinya, gerakan-gerakan itu telah membuat posisi tiang-tiang rumah bergeser sehingga tampak miring. Selain itu, dia mengungkapkan, umumnya atap di puncak bumbungan mengalami kerusakan walaupun tak begitu berarti.

Rumah-rumah di Nias bagian utara, seperti Desa Tumori, umumnya disangga oleh balok-balok kayu berbentuk letter X yang disebut diwa. Diwa menahan lantai rumah di bagian kolong, selain ada pula siloto yang berupa kayu panjang yang menempel di bagian bawah papan lantai rumah tersebut. Siloto langsung menahan lantai rumah, dan merupakan bagian kayu yang paling elastis. Ada juga gohomo, yaitu kayu-kayu yang tegak lurus menopang dan memagari seluruh kolong rumah sehingga omo hada semakin kokoh sekaligus elastis. Gohomo berada di bagian terluar pada kolong rumah, sedangkan siloto dan diwa berada di bagian dalamnya.

Rumah Empatsegi dan Lettter V di Bawomatoluo

Kalau balok penyangga omo hada di kawasan Nias utara berbentuk letter X, maka di Nias Selatan berbentuk letter V. Bentuk itu tampak di rumah-rumah desa tradisional, seperti Bawomatoluo, Hilinawalu Mazingo, Hilinawalu Fao dan sebagainya. Rumah adat di sini pun tidak oval, melainkan berbentuk empatsegi mulai dari atap hingga keseluruhan bagian bangunan.

Bawomatoluo adalah desa tradisional berusia ratusan tahun. Desa ini paling lengkap menyimpan ornamen tradisional Nias Selatan, berada sekitar 8 kilometer dari Teluk Dalam. Setiap orang yang ingin memasuki desa mesti menaiki 91 anak tangga terbuat dari batu hasil pahatan para ahli Bawomatoluo.

Ada satu rumah paling besar di sini, yaitu omo sebua sebagai tempat bermukim raja atau kepala suku. Di halaman sebelah kiri rumah tersusun batu empatsegi setinggi dua meter dengan pijakan sekira 45 centimeter di bawahnya. Batu ini menjadi tempat para prajurit Bawomatoluo untuk memperlihatkan kemampuan lompat mereka—kini merupakan ikon pariwisata Nias: lompat batu. Lalu persis di halaman depan rumah terdapat batu-batu besar yang terpahat rapi untuk duduk raja beserta tetua adat atau tamu-tamu desa.

Selain di Bawomatoluo, setiap desa tradisional di Nias Selatan juga memiliki omo sebua. Namun, kini atap omo hada di desa-desa itu, termasuk Bawomatoluo, rata-rata sudah tidak asli lagi dari rumbia. Semua diganti dengan seng. Demikian pula atap omo sebua sudah menggunakan seng. Perubahahan ini, menurut Pikiran Nehe dari Dinas Pariwisata dan Kebudayaan, terjadi setelah dilakukan pemugaran. Soalnya, katanya, rumbia untuk atap omo hada mulai jarang diproduksi di Nias, padahal kebutuhannya sangat besar. Misalnya, omo sebua saja membutuhkan sekitar dua ribu lembar atap rumbia, belum lagi rumah-rumah lainnya. Namun, tambahnya, perubahan atap dengan seng tidak mengubah desain asli omo sebua. “Selain Bawomatoluo, ada dua desa lagi memiliki omo sebua yang tetap akan dipertahankan, yaitu di Desa Hilinawalu Mazingo dan Hilinawalu Fao,” ungkap Nehe. Ini untuk menjaga dan melestarikan kekayaan budaya Nias Selatan.

Ciri asli juga masih tampak dari pintu masuk omo sebua di Bawomatoluo. Setiap orang mesti masuk melalui pintu dari bagian bawah kolong rumah. Interior rumah pun masih terjaga, dimana dapur terdapat di ruangan tengah dan satu lagi di bagian belakang. “Posisi dapur di ruangan tengah menandakan bahwa omo sebua adalah milik semua rakyat desa ini,” kata Pikiran Nehe.

Ornamen Nias di Omo Sebua

Ornamen-ornamen yang melambangkan kekayaan budaya terpasang di dinding omo sebua, seperti tambur besar fondrahi, rangkaian puluhan tengkorak babi, peralatan perang khas Nias, dan aneka hiasan lainnya. Bangunan omo sebua yang lebih besar, berlantai tinggi, dan berada di tengah desa, membuat raja atau kepala suku dapat mengamati seluruh desa tanpa keluar dari rumah. Tetapi kalau dia ingin mengumpulkan rakyatnya maka cukup dengan memukul fondrahi.

Hikayat Mana’o, seniman yang bermukim di Bawomatoluo, mengemukakan banyak orang sudah mengunjungi omo sebua pada desa-desa tradisional di Nias dan Nias Selatan. Namun, menurutnya, setelah mengunjungi Bawomatoluo mereka mendapatkan ternyata omo sebua di sini paling unik menggambarkan kekayaan budaya Nias. “Ornamen omo sebua dan seluruh desa Bawomatoluo dianggap paling lengkap serta menarik,” katanya. Salah satu ornamen itu terlihat pada seni pahat batu yang juga unik di desa ini, mulai dari tangga masuk, lompat batu hingga aneka perkakas bebatuan di halaman omo sebua.

Dulu, menurut Mana’o, untuk membangun omo sebua saja ada tujuh tahap yang mesti dilampaui oleh leluhur mereka, mulai dari pembangunan fondasi hingga ke atap. “Setiap tahap biasanya diselesaikan dengan mengadakan upacara yang mengorbankan puluhan ekor babi,” ungkapnya. Maka sampai tahap terakhir ada ratusan ekor hewan itu dikorbankan untuk membangun satu omo sebua. “Semua tengkorak kepala babi itu dipajangkan di bagian dalam rumah untuk menunjukkan kebesaran omo sebua,” jelas Mana’o.

Saat ini balok-balok berletter V berukuran besar yang menyangga omo sebua mulai terlihat lapuk. Namun rumah yang kini dihuni oleh generasi kelima raja Bawomatoluo masih kokoh berdiri, padahal bangunan utamanya sejak dari fondasi, lantai dan rangka rumah hingga dinding-dinding sama sekali tak menggunakan paku. “Omo hada—termasuk omo sebua—memang merupakan bangunan knock down, tanpa paku,” kata Solistis Dachi, kepala Dinas Pariwisata dan Kebudayaan Nias Selatan. Ini membuatnya menjadi unik dan tahan dari guncangan gempa. Saking uniknya, dia mengatakan, ratusan tahun lalu penjajah Belanda pernah membawa satu omo sebua ke negerinya beserta satu keluarga orang Nias yang ahli untuk merancang bangunnya kembali di sana. “Sampai kini omo sebua itu masih ada di Kopenhagen, Denmark,” ungkapnya.
