Judul: Penggerombolan kecamatan-kecamatan di kabupaten Subang berdasarkan pada kondisi dan potensi daerah
Abstrak: Dalam menentukan kebijaksanaan pembangunan setiap daerah tidak lepas dari kondisi dan potensi yang ada pada daerah tersebut. Dengan mengetahui kelompok kecamatan dan ciri-cirinya akan terlihat kelompok mana yang relatif lebih maju dibandingkan dengan kelompok lain pada peubah. yang diamati. Dengan analisis komponen utama menghasilkan 4 dan. 5 komponen sebelum dan sesudah pemekaran kecamatan. dengan peubah-peubah yang mendominasi komponen utama relatif sama. Keempat komponen utama sebelum pemekaran tan kecamaadalah potensi sumberdaya manusia, sarana pengem- bangan sumberdaya manusia, potensi daya guna lahan dan perkembangan desa. Sedangkan kelima komponen sesudah adanya pemekaran adalah potensi sumberdaya manusia, perkembangan wilayah, pendidikan, ketenagakerjaan potensi dan daya guna lahan. Penggerombolan kecamatan-kecamatan yang ada di Kabupaten Subang berdasarkan potensi dan kondisi daerah menghasilkan empat kelompok dengan sebagian kelompok mencerminkan pola pemanfaatan lahan pertanian…dst

Judul: Pengelompokan kecamatan-kecamatan di kabupaten Demak
Abstrak: Pengelompokan kecamatan-kecamatan berdasarkan potensi prasarana yang ada di tiap kecamatan merupakan salah dan satu cara pendeskripsian pembangunan yang telah dilaksanakan. Analisis komponen utama nonparametrik merupakan salah satu bentuk perluasan metode analisis komponen utama yang digunakan jika data yang dipakai cenderung heterogen atau data bukan diturunkan dari populasi yang menyebar normal. Analisis komponen utama digunakan untuk mereduksi peubah menjadi beberapa komponen utama yang merupakan kombinasi linear dari peubah-peubah asal. Analisis gerombol merupakan salah metode untuk menge- lompokkan beberapa individu ke dalam beberapa kelompok, dimana keragaman dalam suatu kelompok lebih kecil dari pada keragaman antar kelompok. Dengan demikian pengelompokan kecamatan-kecamatan dapat digunakan untuk mengevaluasi pemerataan pembangunan. Kelompok-kelompok kecamatan yang terbentuk pada tahun 1984-1990 cenderung stabil yaitu Kecamatan Demak, Mranggen dan Karangawen tergabung dalam satu kelompok, Kecamatan Sayung dan Wedung pada satu kelompok, Kecamatan Bonang dan Guntur pada satu kelompok dan kecamatan sisanya membentuk satu kelompok lain…dst

Judul: Utilization of hydrolized duckweed (Lemna minor) meal as a soybean replacement in Nile tilapia (Oreochromis niloticus) diet,
Abstrak: Tilapia is a fast growing fish widely cultured in many tropical and sub tropical countries. The recent production figures reported our global production estimates for 2015 is 5,576.8 metric tons. In developing countries the major challenges facing aquaculture industry is high cost of production associated with fish feeds. Feed represents 40-70% of operating costs for aquaculture operations, increasing expenses and potential declining supplies soybean meal have led scientists to search for less expensive but compatible alternative protein sources for fish feed; most of which are based on animal or plant protein sources. The objectives of study was to determine the incubation period for hydrolysis of duckweed and to evaluate the use of hydrolized duckweed as aprotein source for the growth performance of Nile tilapia Three experiments were conducted to determine the composition and digestibility of hydrolyzed duckweed meal by sheep rumen liquor as the replacement of soybean meal in the diet of Nile tilapia. The first trial examined the effectivity of sheep rumen liquor enzyme to decrease crude fiber contents of (DWM), the added volume of sheep rumen liquor was 100 ml/kg DWM and then it was incubated for 0, 12, 24 hr . The second trial was to evaluate the apparent digestibility of hydrolyzed DWM for Nile Tilapia, apparent digestibility were determined using chromic oxide indicator added to both reference diet and test diets. The feed ingredients used in the trial were hydrolyzed DWM (HDWM) and unhydrolyzed DWM (DWM). Ten fish with an average weight of 18±0.36g were used in the trial and reared in the aquarium of size 30×40×50cm for 15 days; feces were collected from three replicates using a fecal collection column attached to the aquarium. Third trial was to evaluate the growth performance of Tilapia fed test diet with hydrolyzed Duckweed meal (HDWM). The experimental design was set according to completely randomized design with four treatments and three replicates of HDWM inclusion levels that is 0%, 15%, 30% and 45%. Nile tilapia fish with initial body weight of 18±0.36g was kept in 12 units aquarium size of 30×40×50cm at stocking density of 10fish/aquarium, the fish were fed two times a day at 08:00am and 16:00pm to apparent satiation for a period of 60 days. The results indicated that duckweed meal (DWM) hydrolyzed with 100 mL/kg and incubated for 24 hrs showed the lowest crude fiber contents of 13.68% compared to other treatments. Total digestibility of hydrolyzed duckweed (HDWM) meal was 87.3% compared with unhydrolyzed duckweed (DWM) which was 66.8%. Total final weight (TFW), survival rate (SR), specific growth rate (SGR), feed conversional rate (FCR) and protein retention (PR) shows growth performance at 15% inclusion. The results of this study showed that 100mL/kg sheep rumen liquor at incubation period of 24 hr can be suitable for hydrolysis of duckweed to reduce crude fiber also hydrolyzed duckweed can substitute soybean meal at an incubation rate of 15% in the diet of Nile tilapia and had the same growth and FCR with control diet
