Abstract

Large amount of active volcanoes distribution makes Indonesia a country vulnerable to lahar flow. Although lahar flow is categorized under volcanic eruption secondary disaster, it has large impacts in environmental, social, economic, infrastructure and casualties. For example, the incident of lahar flow disaster triggered by high rainfall was occurred in Putih River Magelang, on 24th January 201 . This study discusses the effect of rainfall intensity on lahar flow velocity and height. This study was carried out using a numerical model, SIMLAR 2.1, in Putih River, located on western slopes of Merapi Volcano, Magelang, Central Java. Modeling was performed by using several rain intensity scenarios, i.e. 60mm/hour, 70mm/hour, 80mm/hour, 90mm/hour and 100mm/hour. The velocity of lahar flow simulated by the model was validated using lahar flow velocity data from field measurement. The results showed that rainfall intensity has linear correlation with lahar flow velocity and height. Higher rainfall intensity results in higher lahar flow velocity and height. In addition, the modelling result also showed that the largest lahar flow velocity (2,88m/s) occurred when the rainfall was 100mm/hour and has a deviation of 17.71% compared to previous observations. In average, lahar height in the River increases around 24.31% when the rainfall increases 10 mm/hour.

Abstract

Laju perkembangan yang pesat pada setiap sektor kehidupan di dataran pantai Surabaya-Pasuruan, Provinsi Jawa Timur, menyebabkan permintaan air bersih terus meningkat. Ironisnya, di daerah ini total kebutuhan akan air bersih tersebut masih tergantung pada air tanah. Kecenderungan peningkatan pemakaian air tanah tersebut dapat menimbulkan dampak negatif terhadap kondisi air tanah berupa penurunan kedudukan muka air tanah, dan dampak lainnya berupa intrusi air asin (air laut). Saat ini batas sebaran air tanah payau-asin pada akuifer tidak terkekang dari garis pantai di daerah Waru mencapai 3,3 km, Sidoarjo 10,8 km, Candi 5,9 km, Tanggulangin 9,9 km, dan Porong 8,7 km. Di daerah WatutulisWonoayuPopohBuduranSedati, air tanah payau atau asin pada akuifer terkekang terdapat pada akuifer yang dibentuk oleh batuan dari Formasi (F) Pucangan, berada pada kedalaman lebih dari 48 mbmt (m bawah muka tanah) di sekitar Buduran dan lebih dari 80 mbmt di sekitar Watutulis. Di daerah PulokertoKedungsari air tanah payau-asin dijumpai dalam akuifer pada kedalaman lebih dari 24 mbmt, yang merupakan batuan dari Formasi. Notopuro. Untuk mencegah dan mengurangi dampak negatif yang mungkin terjadi terhadap kondisi air tanah, maka diperlukan upaya pengendalian pemakaian air tanah, agar terjamin kelestarian pemakaiannya.

Abstract

Many hydraulic structures in Indonesia are built on peat soil, especially in Sumatra, Kalimantan and Papua. This soil has bad geotechnical characteristic for building foundation, because its low of shear strength, high potential of land subsidence and consolidation occured in a long term. One way to overcome this issues is using pile foundation. Therefore, a research was conducted in order to found foundation technology of hydraulic structure for peat soil using cerucuk, sand pile and concrete pile. This development of technology being conducted using geotechnical investigation and numerical modeling. The usage would be more effective when embankment strain is distributed evenly and not concentrated on the center of embankment. The search of alternative foundation is narrowed to the efficiency of the foundation design and the methods of implementation. Physical model results show that support capacity of the pile did not significantly increased in every increment in length, the increase instead happened when the tip of the pile deep in mineral soil layer below the peat layer. The foundation type made of concrete firmly in place give a supporting capacity 4 times compared to pile, while combination of pile with sand increase the pile supporting capacity to 2 times only, and pile of sand covered with PVC pipe has a supporting power that is almost the same with pile. Based on that, the concrete foundation type casted in place can be substitute alternative for pile.

Abstract

Identification of climate change impact to the rainfall pattern in Sumatera and Kalimantan becomesinteresting because of its climate variability and nonclimate prediction zone if compared with Java whichhas onlyone type of climatewith nonclimate predictionzone that canbe neglected.Thelimited availabilityof rainfall data causes the approach leads to analyze average rainfall duration in certain threshold.Thedetermination of rainfall duration boundary is based on the Oldeman climate classification for crop andsecond crop, i.e. 100200 mm.Analysis of the trend of average rainfall duration in various thresholds,indicates correlation between length and climate pattern.If compared to the equatorial pattern, themonsoon climate can be classified as robust toward climate change, although the wet season length is muchshorter. In equatorial areas,change of rainfall duration is clearly detected and generally showing a negativetrend oralongerdryseason.

Abstract

Sources of methane emissions from reservoirs are still not widely known in Indonesia. The Research regarding the methane emission source in undated reservoirs is very important to be done to gain data and information, therefore the global warming issues that associated with the methane emission can be solved. This paper discussing about the methane gas emissions that is influenced by the spread of C-organic at the Wonogiri reservoir. Identification of the availability of C-organic, water and sludge sampling was taken at some locations supposed to represent similar conditions. Results of labolatory analysis indicated that the magnitude of the methane production is highly dependent on the C-organic inputs from the water inflow of river catchment or activities involving organic material in the reservoir. Highest potential of methane production was encountered at the river mouth of Kali Kedawung and near the floating fish cultivation. Total potential of methane production of water in the Wonogiri reservoir is at an elevation of 134.7 m with 321.75 million m3 of water volume and 50 km2 of surface water area, stored a methane production of approximately 437.6 tonnes. Mitigation of methane emissions is to be done by reducing C-organic inputs to the reservoir by controlling the land-use in the catchment and reduce floating fish cultivation in the reservoir.

Abstract

Kabupaten Garut merupakan salah satu wilayah yang banyak memiliki potensi energi listrik tenaga air karena kontur geografisnya berupa daerah pegunungan dengan aliran sungai yang deras. Salah satu sungai yang memiliki potensi untuk dikembangkan sebagai pembangkit listrik adalah Sungai Cikawung. Untuk menggali lebih jauh potensi yang ada khususnya terkait pembangkitan tenaga listrik, diperlukan suatu studi kelayakan. Studi ini dilakukan untuk mengetahui tingkat kelayakan rencana pembangunan pembangkit listrik tenaga minihidro di Desa Sukamaju Kabupaten Garut Provinsi Jawa Barat dilihat dari segi teknis dan ekonomis. Metodologi yang digunakan mencakup kegiatan survei lapangan, analisis hidrologi, perhitungan daya dan energi, perencanaan bangunan sipil, perencanaan peralatan mekanikal elektrikal, dan analisis ekonomi. Dari hasil studi didapat bahwa lokasi rencana pengembangan minihidro memiliki potensi debit 2,0 m3/det, head 200 m dan 330 m, dengan potensi daya listrik 4.719 kW. Bendung didesain berdasarkan debit banjir dengan periode 100 tahun, sedangkan bangunan pengambilan, saluran pembawa, dan bangunan pelimpah didesain dengan kapasitas 20% lebih besar dari debit rencana turbin. Turbin yang akan digunakan adalah turbin Pelton berjumlah 2 unit berdaya 1.159 kW dan 3.560 kW. Analisis finansial memberikan gambaran bahwa rencana pengembangan minihidro ini layak untuk ditindaklanjuti karena memiliki nilai NPV Rp65.118.441.870,- dan IRR 26,07%.
