Abstract

Penurunan ketersediaan air akibat perubahan penggunaan lahan telah terjadi di Kabupaten Konawe, sedangkan permintaan air cenderung meningkat. Dari segi keberlanjutan penyediaan air, hal ini cukup mengkhawatirkan. Penelitian ini bertujuan menganalisis: (1) tingkat keberlanjutan, (2) faktor penting yang memengaruhi keberlanjutan, (3) peran kelembagaan dalam pengelolaan air baku berkelanjutan di Sub DAS Konaweha. Hasil analisis Multi Dimensional Scalling (MDS) dengan Rap-Konawe menunjukkan bahwa status keberlanjutan pengelolaan air baku di Sub DAS Konaweha kurang berkelanjutan dengan indeks 41,40%. Nilai indeks keberlanjutan diukur pada 5 dimensi yaitu ekologi, ekonomi, sosial, teknologi, dan kelembagaan dengan nilai indeks masing-masing secara berurutan 52,36%, 36,93%, 34,16%, 35,39% dan 35,39%. Hasil analisis Interpretative Structural Modelling (ISM) menunjukkan tiga unsur yang perlu diperhatikan yaitu kendala, kebutuhan, dan lembaga. Kendala penting yang dihadapi adalah penurunan fungsi daerah tangkapan air karena berkurangnya vegetasi dan kurangnya koordinasi pengelolaan sumber daya air antara para pemangku kepentingan. Kebutuhan program yang harus menjadi fokus perhatian adalah peningkatan pengetahuan dan keterampilan personil kantor pemerintah, serta peningkatan kesadaran stakeholder. Adapun lembaga yang menjadi faktor kunci untuk program ini adalah BPDAS Sampara dan Dinas Kehutanan Kabupaten Konawe.

The AF watershed provides water, land use, economic and other environmental services. However, the excessive exploitation is a major threat for the existence of the AF watershed. The degradation of the AF watershed function such as reduction in river debit, increase of critical land, land use change as well as the problem of poverty. The upstream area is intended as a conservation area where Watu Ata nature preservation park is located, the bamboo forest and Bajawa as the capital city of Ngada Regency. The downstream area is not only as capital city of Nageko Regency but also as paddy field area. One of the activity to improve the watershed function is through a comprehensive and sustainable management policy design based on characteristics and carrying capacity of the AF watershed. This research was conducted in April-May 2018 and the the purpose of the study is to analyzed key factors and establishing an alternative for sustainable management policy development of AF watershed using a prospective method. This study using mainly primary data obtained from the seven local experts through the filling of the questionnaire. The result shows that there are 22 attribute factors and it identified as 10 key factors. The main two key factors are bamboo cultivation, processing technology of bamboo, enlargement of bamboo cultivation area and practicing the soil and water conservation technique. The 10 key factors then become input for designing the management policy of AF watershed. Bamboo become the dominant and key factor because bamboo could be developed into biomass energy plant and it serves social, economic and ecological values for the local people of Ngada and Nagekeo Regency. Bamboo cultivation has a good prospect financially for the local people.

Abstract

ABSTRAKPengelolaan DAS Aesesa Flores di Provinsi Nusa Tenggara Timur menjadi penting dan prioritas karena isu daerah kepulauan, kesulitan mendapatkan air bersih, ketersediaan pangan dan kemiskinan, serta keterbelakangan pembangunan. Keberhasilan pengelolaan DAS yang berkelanjutan sangat ditentukan oleh kinerja kelembagaannya. Penelitian yang dilaksanakan pada bulan April-Mei 2018 ini bertujuan untuk menganalisis peran kelembagaan ditinjau dari aspek kendala, kebutuhan program dan actor/lembaga yang berperan dalam pengelolaan DAS Aesesa Flores. Data yang digunakan adalah data primer dan sekunder, khusus data primer diperoleh dari 7 (tujuh) orang pakar melalui pengisian kuesioner. Metode analisis data menggunakan pendekatan ISM (Interpretative Strutural Modellling) untuk menentukan factor kunci yang paling berperan dalam pengelolaan region hulu, tengah, dan hilir DAS Aesesa Flores. Hasilnya bahwa pengelolaan DAS AF yang berkelanjutan masih menghadapi 9 kendala pokok, membutuhkan 11 program, terdapat 5 aktor utama yang berperan dalam pengelolaan DAS AF yakni BPDAS Benain Noelmina, Forum DAS NTT, BWS NTT2, Masyarakat dan LSM. Pengelolaan DAS AF masih bersifat eksploitasi, belum mengarah pada pembangunan berkelanjutan dan tidak didukung dengan kelembagaan yang mumpuni sehingga diperlukan segera upaya untuk mengatasi kendala, implementasi program pokok, dan peningkatan peran dan kordinasi actor/pelaku pengelolaan DAS AF yang berkelanjutan.ABSTRACTThe management on the Aesesa Flores (AF) watershed is important, particularly because of the imminent issues of clean water needs, food securities and a poverty rate of the local communities. The success of this management is influenced by the institution and governance in the AF watershed. This study was done from April to May 2018, and the main objective of the study is to determine the key factors that related to the AF watershed management. There were three main elements that were analyzed in this study, namely: (1) the key actors; (2) the key requirements; and (3) the key hindrances that influencing the AF watershed management. This study was using Interpretative Structural Modeling (ISM) to determine the key factors in each element. The data was collected primarily from an in-depth interview with 7 experts in the field of watershed management. The results from this study showed that there were 5 key actors that have the main influence in the AF watershed management, which are: (1) BPDAS (Governmental Watershed Institution); (2) Forum DAS (community forum of AF watershed); (3) BWS NTT2 (Regional River Management Institution); (4) Local communities; and (5) NGO (Non-Government Organization). The results from this study also suggested that the AF watershed management was explorative, thus may lead to unsustainable natural resources usage. Therefore, this study suggested that in order to achieve a sustainable watershed and natural resources usage, the relevant actors need to collaborate together to create a balance action plan that protects the environment, promoting economic growth and social affluence.Keywords: Aesesa Flores watershed, Interpetative Structural Modelling, watershed institution and governanceSitasi: Noywuli, N., Sapei, A., Pandjaitan, N.H dan Eriyatno (2018).

Abstract

Cangkurawok Village is located in the outer of the Bogor Agricultural University area and does not have good sanitation facilities. Disposal of domestic wastewater directly discharges into drainage channels to river. Wastewater treatment plant design from toilets communal divides into three stages. The first stage is determining the location of toilets communal and excreta treatment plant. Location provided by the public is around 5 meters above the surface of the river water. The second stage is the determination of service areas. In this village consists of 70 heads of households as the basic criteria for determining the volume of septic tanks. The last step is determining the design of toilets communal and wastewater treatment unit. This stage requires t he unit options that fits on the selected sites, based on ease of maintenance and no need employ trained operators. Waste treatment facility consists septic tank and infiltration well planning. Septic tank volume is 26.5 m3 with the long dimension of 2.75 m, width of 5.5 m and height of 1.5 m plus 0.3 meters for free board. Septic tank serving four toilets communal is built above it, with the division of space for two men and two spaces for women. infi lt rat ion well constructed to absorb the waste liquid vertically through the soil pores. Layers of sand and gravel is spread throughout the wells to assist the flow pattern. Depth and diameter of infiltration well are 3 m and 1 rn, This wells should be placed lower than the drinking water sources and wells, with a minimum distance of 15 m.

Abstract

Peningkatan Efisiensi irigasi dapat dilakukan pada saat penyaluran (conveyance), distribusi maupun aplikasi. Kehilangan air dalam bentuk evaporasi, bocoran, rembesan, perkolasi maupun air yang terbuang perlu ditekan sekecil mungkin. Tujuan penelitian ini adalah mengkaji perkolasi lahan sawah yang dilengkapi dengan lapisan kedap buatan dalam kerangka irigasi hemat air dan peningkatan efisiensi. Lapisan kedap dibuat dengan cara memadatkan lapisan tanah di bawah lapisan olah dengan menggunakan soil stamper dan baby roller. Ketebalan lapisan kedap diperoleh sekitar 14 cm dan kekerasan maksimumnya berkisar antara 9.41 kg/cm2 – 13.28 kg/cm2. Besar perkolasi diperoleh berkisar antara 7.9 sampai 21.3 cm/hari. Perkolasi yang relative lebih kecil diperoleh dari lahan yang dipadatkan dengan baby roller. Tetapi perkolasi yang diperoleh ini masih terlalu besar untuk lahan sawah yang hanya sekitar 4 mm/hari. Hal ini mungkin disebabkan oleh kondisi tanah dari lahan tersebut yang mempunyai perkolasi sangat tinggi (508.8 cm/hari).

Abstract

ABSTRAKPenurunan ketersediaan air dan peningkatan kebutuhan air telah terjadi di Kabupaten Konawe Provinsi Sulawesi Tenggara. Hal ini disebabkan karena perubahan penggunaan lahan akibat eksploitasi lahan secara terus menerus sehingga terjadi penurunan kapasitas infiltrasi dan peningkatan aliran permukaan. Berdasarkan permasalahan diatas maka diperlukan strategi pengelolaan dan pengembangan peran kelembagaan sehingga pengelolaan air baku untuk penyediaan air bersih di Kabupaten Konawe dapat berlangsung secara berkelanjutan. Penelitian ini dilakukan dengan tujuan: (1) menganalisis peran kelembagaan ditinjau dari aspek kendala yang dihadapi, kebutuhan program pemerintah terkait, dan lembaga yang berperan dalam pengelolaan air baku untuk penyediaan air bersih berkelanjutan di Kabupaten Konawe; dan (2) mengembangkan model kelembagaan pengelolaan air baku untuk penyediaan air bersih di Kab. Konawe dengan metode Interpretative Structural Modeling (ISM). Hasil penelitian menunjukkan bahwa untuk implementasi model, terdapat tiga elemen sistem yang perlu diperhatikan. Tiga elemen sistem dengan masing-masing sub elemen kuncinya yaitu: (1) kendala (menurunnya fungsi resapan air akibat berkurangnya vegetasi pada daerah tangkapan air, dan kurangnya koordinasi dan keterpaduan pengelolaan sumber daya air antar stakeholder terkait); (2) kebutuhan (peningkatan pengetahuan dan ketrampilan aparat SKPD terkait, dan peningkatan kesadaran stake holder terkait); dan (3) lembaga (BP DAS Sampara, Forum DAS Sultra dan Dinas Kehutanan Kab. Konawe). Kata kunci: model, kelembagaan, air baku, air bersih, ISM   ABSTRACTDecreased water availability and increased water demand has occurred in Southeast Sulawesi Konawe. This is caused by changes in land use due to continuous exploitation of land resulting in a decrease in infiltration capacity and increased surface runoff. Based on the above issues will require the development of management strategies and the role of institutions, so that the management of raw water for water supply in Konawe District can take place in a sustainable manner. This study was conducted with the aim of: (1) analyze the role of institutional on the aspects of constraint, the needs related government programs, and agencies that play a role in the management of raw water for water supply sustainable in Konawe district, and (2) develop a model of water management institutions of water supply in the Konawe District with Interpretative Structural Modeling method (ISM). The results showed that for the implementation of the model, there are three elements of the system that need to be considered. Three elements of the system with each of the key sub elements, namely: (1) constraint (decreasing function of water absorption due to reduced vegetation in the catchment area, and the lack of coordination and integration of water resources management among related stakeholders), (2) needs (increased knowledge on education and skills related apparatus, and an increased awareness of all related stakeholders), and (3) agency (BP DAS Sampara, Forum DAS Sultra and Dinas Kehutanan Konawe District) . Keywords : models, institutional, raw water, clean water, ISM
