Interpretasi Bawah Permukaan Gunung Merapi dengan Analisa Gradient dan Pemodelan 2d Data Gayaberat

Gravity method research has been done in Merapi Volcano area. The data has been measured by BPPTKG Yogyakarta team with the number of point as much as 164 points. The aim of this research are to identify the subsurface structure and locate the position of Merapi Volcano magma chamber, so that a gradient analysis and 2D modelling based on Bouguer anomaly has been done. Gradient analysis apply first horizontal and second vertical gradient that is used to know the location and the type of structure on the research area. The result from this research show Bouguer anomaly with range value around -8.79 mGal to 305.46 mGal. The 2D modelling show Merapi volcano subsurface model that consist of 5 layers with the position of magma chamber is located in the third layer about 3300 m below the Merapi summit or 700 m below the mean sea level. Based on gradient analysis, there is a normal dipfault structure. This faults is indicated to be formed a basin on the Merapi summit toward westward leading directly to the Patuk Alap Alap Mountain and Kali Krasak

Airport Factor in Flight Delays in Indonesia

Airport is a vital subsystem in the air transport system which has an important and strategic role in smoothening air traffic, so that an airport must be designed to be always ready in all situations and conditions to serve airline flights securely, orderly, smoothly, and quickly. The frequent delay faced by Indonesian domestic scheduled airlines is not fully caused by internal factor of the companies. Instead, it can be caused by the airport factor. The problems faced by airports in Indonesia which have impacts on the performance of flight punctuality among other things are capacity, slot time, quality of flight navigation devices, accessibility, professionalism of airport and ATC human resources, infrastructure, facilities, equipment, and the human resources handling security and safety of flights in airport. This article recommends that an in-depth study should be carried out to map the interrelations between the airport factor in the flight delay related to facilities integration and the airport authority in the flight activities in Indonesia

Food Demand Analysis of Indonesian Households with Particular Attention to the Poorest

The purpose of this study is to analyze the demand responses of Indonesian households to food prices, income changes and other socioeconomic factors. The underlying assumption here is that inadequate information on household food expenditure patterns which vary across income groups and regions may have its contribution to the persistence of food insecurity. We use the Indonesian Family Life Survey data and methodologically we employ an extended form of the Quadratic Almost Ideal Demand System model which includes demographic and regional factors. Results reveal the well known pattern that food demand behavior varies significantly between urban and rural households as well as income groups. The poorest households consume relatively more staple food as well as alcohol and tobacco goods while the richest households consume relatively more meat, snack and dried food. It is shown that the poorest households’ expenditure elasticity on alcohol and tobacco is high implying that the poorest households transfer their extra resources on alcohol and tobacco goods instead of more nutritious food items. Results also show that price and expenditure elasticities have changed across time (1997-2007). Own price elasticities have increased for most food items implying that people have become more responsive to changes in prices. In contrast, the expenditure elasticity has declined for most food items (except for ‘alcohol and tobacco goods’) which would imply welfare improvement since the 1997 crisis.food demand, QUAIDS, Indonesia, Consumer/Household Economics, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, D11, D12,

Analisis Supposed Capable Fault sebagai Data Dukung Rencana Tapak PLTN Bojonegara, Propinsi Banten

ANALISIS SUPPOSED CAPABLE FAULT SEBAGAI DATA DUKUNG RENCANA TAPAK PLTN BOJONEGARA, PROPINSI BANTEN. Lokasi sesar dan daerah beradius 150 km dari garis sesar atau zona sesar merupakan daerah yang tertolak atau dihindari dalam pemilihan daerah tapak interes PLTN. Tujuan penelitian adalah untuk mengidentifikasi keberadaan sesar permukaan atau sesar kapabel di lokasi tapak PLTN. Metodologi penelitian meliputi interpretasistruktur sesar, analisis seismik refleksi di darat dan laut, analisis seismotektonik, dan menentukan daerah terbebas bahaya pensesaran permukaan. Wilayah studi regional, yaitu radius 150 km dari daerah interes, mencakup Propinsi Banten, DKI Jakarta, Jawa Barat, dan Sumatera Selatan (sebagian Lampung). Hasil interpretasi citra landsat, struktur sesar memperlihatkan pola yang berarah timur laut - barat daya yang diwakili oleh Sesar Cimandiri, barat laut – tenggara yang diwakili oleh Sesar Citandui, Sesar Baribis, Sesar Tangkuban Perahu. Pola sesar yang berarah timur laut – barat daya diperkirakan merupakan pola struktur mendatar sinistral (left lateral faults), dan pola sesar yang berarah barat laut – tenggara merupakan sesar mendatar dekstral (right lateral faults). Berdasarkan data seismik di darat, sesar yang menembus sampai Formasi Cisubuh dikategorikan sebagai Supposed Capable Fault. Analisis sekuen stratigrafi seismik laut dikorelasikan dengan satuan umur pengendapan pada Zaman Plistosen, dimana terbagi dalam QT (Batas Tersier dan Plistosen Awal), Q1 (Batas Plistosen Awal dan Plistosen Tengah), dan Q2 (Batas Plistosen Tengah dan Plistosen Akhir), suppose capable fault menembus sekuen Plistosen awal hingga akhir. Hasil analisis seismotektonik terdapat sesar kapabel diperkirakan (supposed capable fault)

Marine Geological and Hydro Oceanographic Data for Site Seaport Location Selection at Sampit Bay and Its Surrounding, East Kotawaringin, Central Kalimantan

Sampit Bay is one of many main gates to enter the Central Kalimantan Province, because there is Mentaya River Mouth as an access to the Sampit Harbour as a main port at its province. Until now, the Sampit Bay only used as anchored for big ships waiting turn to enter Sampit Port. The methods used are coastal characteristic mapping, seafloor surficial sediment sampling, grain size analyses, echosounding, and current measurement. Sampit bay has sandy coast, sand of sea floor surficial sediment, and gradation of sea floor morphology which is suitable for sea port location. On the other hand, the velocity of the surface and midle current in the bay ranging between 0.1-0.3 m/second which is dominated by south east direction. The mentioned velocity is under threshold for safety ship anchoraged. Beside that, most of the bay open to the wind from west and south west facing Java Sea, where the velocity ranging from 5-13 m/second which is included into weak catagories. Location is recommended to be sea port candidate in the south of Ujung Pandaran.Keywords: Sampit Bay, port location, coastal characteritistic, sea floor surficial sediment, current velocity. Teluk Sampit adalah salah satu gerbang utama memasuki Propinsi Kalimantan Tengah, karena tempat bermuaranya Sungai Mentaya yang merupakan akses menuju ke pelabuhan Sampit sebagai pelabuhan utama di provinsi tersebut. Selama ini teluk Sampit hanya digunakan sebagai tempat lego jangkar kapal-kapal besar yang menunggu giliran untuk berlabuh di Pelabuhan Sampit. Metode yang digunakan adalah pemetaan karakteristik pantai, pengambilan contoh sedimen permukaan dasar laut, analisis besar butir, pemeruman, dan pengukuran arus. Teluk Sampit memiliki jenis pantai berpasir dan sedimen permukaan dasar laut pasir serta morfologi dasar laut yang bergradasi cukup layak untuk lokasi pelabuhan. Disamping itu kecepatan arus permukaan dan menengah di teluk tersebut berkisar antara 0,1-0,3 meter/detik dengan arah dominan ke arah tenggara, dimana kecepatan arus tersebut masih dibawah ambang batas untuk keamanan kapal berlabuh. Disamping itu, sebagian besar teluk tersebut terbuka terhadap hembusan angin arah barat dan tenggara yang berhadapan dengan laut Jawa dimana kecepatan angin yang bertiup antara 5-13 meter/detik dan termasuk dalam katagori lemah. Lokasi yang paling layak untuk lokasi pelabuhan adalah sebelah selatan Ujung Banaran
