Judul: Analisis Permasalahan Sosial Di Propinsi Jawa Barat
Abstrak: Permasalahan saSta! selain berpengaruh terhadap ekonomi juga berpengaruh terhadap stabilitas dan kemajuan suatu daerah. Informasi mengenai keadaan pennasaJ.ahan sasia! ini sangat diperlukan, sehingga dibutuhkan suatu analisis untuk melihat sejauh mana setiap kabupaten dan kota di Jawa Sarat mempunyai tingkat pennasalahan sosial. Penelitian ini menggunakan analisis gerombol dan biplot untuk melihat permasalahan sosial yang ada di daerah Jawa Barat. Analisis gerombol ini menggunakan analisis gerombol tidak hierarki dengan menentukan tiga gerombol. Penentuan tiga gerombol ini didasari pertimbangan subyektif peDeliti dengan harapan bisa di lihat kabupaten dan kota di Jawa Barat menjadi tiga gerombol yang mempunyai karakteristik yang berbeda-beda. Sedangkan analisis biplot untuk melibat posisi relatif dari kabupaten dan kota terhadap peubah-peubah permasalahan sosia! sekaligus membandingkan hasiloya dengan analisis gerombol sebelumnya. Hasil anallsis menunjukkan bahwa Kabupaten Karawang dan Kabupaten Gamt. memiliki permasalahan sosial tinggi. Hampir seluruh permasalahan sosial di kedua kabupaten tersebut berada di atas nilai tengah permasalahan sosial di Jawa Barat. Pennasa1ahan yang paling menonjol adalah anak terlantar, lansia dan keluarga berumah tidak Jayak huni_ Kabupaten Bandung dan Kabupaten Cirebon juga memiliki permasalahan sosial yang tinggi yaitu pada permasa1ahan fakir miskin sedangkan Kabupaten Bogor yang merniliki tingginya _pennasalahan jumlah masyarakat yang tinggal di daerah rawan bencana. Selain kabupaten diatas

Judul: Analisis keterkaitan antara tingkat perkembangan Wilayah dengan perubahan penggunaan lahan di Propinsi Jawa Barat
Abstrak: Tujuan dari penelitian ini adalah untuk mengetahui tingkat perkembangan wilayah dan arah perubahan penggunaan lahan masing-masing Kabupaten/Kotamadya serta mengetahui keterkaitan antara tingkat perkembangan wilayah dengan perubahan penggunaan lahan di Propinsi Jawa Barat. Penelitian dilakukan di wilayah Propinsi Jawa Barat dengan unit pengamatan meliputi 20 Kabupaten dan 4 Kotamadya. Metode yang digunakan terdiri dari tahapan menghitung perubahan rata-rata tingkat perkembangan wilayah dan perubahan penggunaan lahan per tahun, kemudian dilanjutkan dengan analisis komponen utama (Principal Component Analysis) dan analisis korelasi serta analisis gerombol (Cluster Analysis). Berdasarkan tingkat perkembangan wilayah yang ditunjukkan melalui pertumbuhan rata-rata per tahun sektor perdagangan, sektor industri dan ketersediaan fasilitas pelayanan selama kurun waktu 1988-1993, unit-unit pengamatan (Kabupaten/Kotamadya) dikelompokkan menjadi Kelompok wilayah perdagangan dan industri meliputi Kabupaten Bogor dan Tangerang. Kelompok wilayah pusat pelayanan perkotaan meliputi Kotamadya Cirebon dan Sukabumi. Kelompok wilayah pusat pelayanan umum meliputi Kotamadya Bandung, Bogor, dan Kabupaten Subang. Kelompok wilayah pendistribusian barang dan jasa meliputi Kabupaten Bekasi, Majalengka, Karawang, Serang, Tasikmalaya, Indramayu, Kuningan, Sumedang, Cirebon, Ciamis, Lebak, Bandung, Garut, Cianjur, Purwakarta, Sukabumi, dan Pandeglang...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
