The research was conducted in Citarik Sub-Watershed, Sukabumi Regency, West Java Province and part of the Cimandiri Watershed, WS Cisadea-Cibareno. Citarik sub-watershed. Geographically it is located at 6°43'05" - 7°01'15" S and 106°30'50" - 106°41'00"E. The lithology of the research area regionally consists of volcanic rocks, pyroclastic rocks, and sedimentary rocks. Based on the watershed coverage, the tributary of the Citarik River flows from the foot of Mount Salak to the Pelabuhan Ratu estuary. Therefore, the Citarik River has a variety of topography from mountainous landforms to lowlands. The flow of the Citarik Sub-watershed which is mostly located in hilly areas, can be affected by the structure. Through fault fracture density (FFD) analysis, it is possible to estimate the permeable zone to find out its implications for base flow discharge, surface runoff discharge, and total available water discharge. Based on the calculation of the discharge with the water balance approach, the F.J. Mock method, the ratio of base flow and surface runoff in the high FFD zone is greater than that in the low FFD zone. This indicates that more discharge infiltrate than flows on the surface."

"Kebutuhan akan datum vertikal yang akurat di Jawa dan Sumatera sangat mendesak karena pada kedua pulau tersebut banyak dilakukan pembangunan infrastruktur. Saat ini referensi tinggi yang tersedia di Jawa dan Sumatera adalah geoid EGM2008. Hasil penelitian terdahulu menunjukkan bahwa geoid EGM2008 di Jawa dan Sumatera memiliki ketelitian 89.8 cm dan 33.4 cm. Penelitian terdahulu menggunakan asumsi bahwa mean sea level (MSL) berhimpit dengan geoid. Pada kenyataannya, geoid tidak berhimpit dengan MSL. Oleh karena itu, dilakukan penelitian ini untuk mengetahui ketelitian geoid EGM2008 di Jawa dan Sumatera dengan mengasumsikan MSL tidak berhimpit dengan geoid, yaitu dengan menggunakan parameter mean dynamic topography (MDT) dari ocean model. Pada penelitian ini, MDT digunakan dalam penghitungan geoid geometris di Jawa dan Sumatera. MDT yang digunakan adalah hasil simulasi dari asimilasi altimetri dan Hybrid Coordinate Ocean Model (HYCOM). Berdasarkan hasil penelitian, dengan memasukkan parameter MDT pada penghitungan geoid geometris dan melakukan fitting terhadap jaring kontrol vertikal (JKV), ketelitian geoid EGM2008 di Jawa dan Sumatera meningkat menjadi 5.6 cm dan 4.4 cm. Dengan demikian, dapat disimpulkan bahwa geoid EGM2008 sudah mencukupi untuk pemetaan skala besar dan menengah.

The needs for accurate vertical datum in Java and Sumatera are urgent, due to rapid development of infrastructure in both islands. Nowadays, the only vertical datum available in Java and Sumatera is the geoid of EGM2008. Previous research indicates that the accuracies of geoid EGM2008 were 89.8 cm and 33.4 cm in Java and Sumatera, respectively. Those results used assumption that geoid coincides with mean sea level (MSL). In fact, geoid does not coincide with MSL. Therefore, this research was conducted to investigate the accuracy of geoid of EGM2008 using mean dynamic topography (MDT) parameter from an ocean model.

In this research, the mean dynamic topography was introduced to calculate the geoid geometries. The MDT used was the result of assimilation of altimeter data and Hybrid Coordinate Ocean Model (HYCOM). Using MDT parameter has improved the accuracies of the geoid of EGM2008 to be 5.6 cm and 4.4 cm for Java and Sumatera, respectively, after it has been fitted by local reference. Hence, it can be concluded that these accuracies comply for medium and large-scale mapping."

"ABSTRAKThis paper is shown the leading sector in seven regencies in The National Strategic Area of Lake Toba, i.e. Tapanuli Utara, Simalungun, Karo, Dairi, Toba Samosir, Humbang Hasundutan, and Samosir. There are three approaches which used, i.e. the location quotient (LQ) to determine the base sector, sectoral typology to determine the prime sector, and overlay of the base sector and prime sector to determine the leading sector. The data analyzed is the gross regional domestic product (GRDP, PDRB) in the year of 2010 to 2016 at 2010 constant market prices.The result of data analysis show that all of the prime sector are as leading sector and not all of base sector as the prime sector. With the overlay method between the base sector and the prime sector, the leading sector are: (1) agriculture, forestry, and fishing; (2) construction; (3) accommodation and food service; and (4) public administration and defence; compulsory social security. However, only one of them as the leading sector among the seven regencies, namely public administration and defense; compulsory social security sector. From the data analysis, all prime sectors are the leading sector and not all base sectors are the prime sector. So, the overlay results indicate that the prime sector as well as the leading sector. Thus, to determine the leading sector simply by using the approach of sectoral typology."

"Metode moiré telah banyak digunakan terhadap permukaan obyek, yaitu untuk mengukur simpangan sejajar permukaan dan untuk memetakan topografi permukaan, tetapi masih jarang untuk mengukur simpangan tegak Iurus permukaan. Dalam disertasi ini telah diselidiki pengukuran simpangan tegak lurus obyek dengan memanfaatkan metode moire proyeksi. Sebagai kisi proyeksi, digunakan hasil interferensi cahaya laser dari perangkat interferometer Michelson, yang dikenal sebagai kisi maya. Sistem yang dikembangkan terdiri atas dua bagian utama, yaitu bagian optik yang terdiri alas sumbar cahaya laser, interferometer Micheison, dan kamera CCD yang dihubungkan dengan komputer untuk merekam citra. Bagian kedua ialah program pengolah citra yang dibuat khusus untuk penelitian ini. Dalam percobaan digunakan obyek uji berbentuk pelat memanjang yang satu ujungnya dijepit dan ujung lainnya ditekan dengan sebuah mikrometer. Sejumlah citra direkam dari kisi yang terproyeksi pada permukaan obyek, sebelum dan sesudah obyek mengalami simpangan. Oleh program pengolah citra, citra-citra tersebut dikurangkan satu sama lain untuk memperoleh pola moiré. Dari kerapatan pola moiré, simpangan permukaan dapat disimpulkan. Pemakaian komputer mempercepat proses perekaman dan pengolahan citra. Untuk perekaman 10 citra dan pengolahannya, pola frinji moiré dapat diperoleh dalam waktu sekitar 30 menit. Dalam percobaan dilibatkan berturut-turut kisi maya dengan 3 kerapatan yang berbeda. Kisi yang rapat mempunyai periode 0,817 mm pada permukaan obyek dan memberikan ketelitian pengukuran simpangan sebesar 1,85 mm. Kisi yang lebih renggang mempunyai periode 1,196 mm dan menghasilkan ketelitian 1,01 mm, sedangkan kisi yang paling renggang mempunyai periode 1,419 mm dan memberikan ketelitian 1,51 mm. Diperoleh bahwa simpangan yang kecil menghasilkan periode frinji moiré yang besar, sehingga dapat melampaui bidang perekaman. Karenanya terdapat batas simpangan minimum yang dapat diukur. Dinyatakan dalam W sebagai simpangan pada lokasi mikrometer, batas tersebut berkisar dari W =4 mm dengan kisi yang rapat hingga W = 6 mm dengan kisi yang paling renggang. Di pihak lain, kisi yang rapat pada simpangan yang besar akan menghasilkan frinji moire yang sangat berdekatan sehingga menyulitkan penentuan periode frinji moire. Dalam percobaan dengan kisi yang rapat, hal tersebut terjadi waktu W > 12 mm.

The moiré method has been extensively used for the surface measure of an object, i. e. to measure the in-plane displacement ofthe surface and to map the surface contour. Howe ver, so far the method is rarely utilized to measure the out-of-plane displacement. In this dissertation, the measurement of the out-ojlplane displacement has been investigated by employing projection moiré method As the projected grid o virtual grating formed by interjerencs of laser light from a Michelson interferometer is involved The system developed in this research consists of two main parts. The optical part comprises a laser source, a Michelson interferometer, and a CCD camera coupled to a computer for recording the images. The second part is an image processing program that is specially developed for this work. In experiments, the object takes the form of a cantilever clamped at its one and pushed at the other end by a micrometer. Several images are recorded from the projected gratings at the object surface, before and after displacement. By an image processing program, the images are subtracted one from the other to obtain moiré fringe patterns. From the fringe period surface displacement can be determined. The use of the computer has speeded up the recording and the processing of the images. The whole sequence of recording 10 images successively and processing them to obtain the moiré fringe pattern takes no longer than 30 minutes. Three virtual grating with diferent periods have been involved in the experiments. The most dense grating has a period of 0.81 7 mm at the object surface, resulting the in an accuracy of the displacement measurement of 1. 85 mm. The coarser grating shows a period 1.196 mm and yields an accuracy of 1.01 mm. The period of coarsest grating is 1.419 mm, resulting in an accuracy of 1. 51 mm. In the case of small surface displacement, large moiré fringe periods have been produced which may exceed the recording frame size. Consequently, there is a minimum value of the measurable displacement. This minimum displacement ranges from W = 4 mm for the most dense grating to W = 6 mm for the coarsest virtual grating, W being the object displacement at the micrometer location.. On the other hand, large surface displacement observed with dense virtual grating produces small periods of the moire fringes, which make it very difficult to evaluate. In the experiments it occurs of W > 12 mm."
