Penelitian ini bertujuan untuk mengetahui perbandingan produksi dan pendapatan petani antara pengguna benih padi bersubsidi dan tidak bersubsidi. Penelitian ini dilaksanakan di Kabupaten Bogor, yakni: Kecamatan Tenjolaya untuk responden petani pengguna benih padi bersubsidi dan Kecamatan Dramaga untuk responden petani yang menggunakan benih padi tidak bersubsidi. Penelitian  dilaksanakan dari Februari hingga April 2016. Jumlah responden penelitian sebanyak 40 orang, yang terbagi menjadi 20 responden pengguna benih padi bersubsidi dan 20 responden yang menggunakan benih padi tidak bersubsidi melalui in depth interview dengan metode purposive sampling. Hasil penelitian menunjukkan bahwa petani yang menggunakan benih padi bersubsidi memiliki tingkat produktivitas dan pendapatan yang lebih tinggi dibandingkan dengan petani yang menggunakan benih padi tidak bersubsidi. Hal tersebut dipengaruhi oleh penggunaan input produksi yang lebih dominan pada pupuk organik dan benih bersertifikat.

Economically, Indonesia's tradebalance deficit with export figures of herbal products continues to decline. That is, the existence of free tradeagreements is adversely affected by the low competitiveness of herbal products against imported products thatcirculate in Indonesia. In the midst of adversity free trade, in 2015 has agreed a free trade agreement between theASEAN countries (EAC). Will EAC able to lift Indonesian herbal products from the domestic market?.

Abstract

Most rice farmers in Pamijahan Subdistrict cultivate in traditional way and have relatively low income. Farmer’s low income was caused by low productivity so farmer welfare also decrease. Traditional methods in cultivation also affect the environment because of high usage of chemical fertilizer. This community service program aims to increase farmer’s income in Pamijahan Subdistrict by introducing System of Rice Intensification (SRI) method using organic fertilizer. The main activities are: instituional strengthening, SRI training and cultivation practice (pilot project). The expected outcome of this community service activity is to increase production by using less input and to get higher selling price for organic rice. There are four steps in this program is: planning, organizing, actuating and controlling. The sequence is: 1) Program preparation, consist of: program socialization, institutional strengthening, cooperation with SRI trainer, preparation of experimental field, seed and agricultural equipment; 2) Institutional strengthening with rice farmer; 3) SRI method training with trainers from Nagrak Organic SRI Center to change farmer’s mindset and train farmers about SRI cultivation method; 4) Cultivation in experimental field (650 m2), where farmers practice to cultivate rice with SRI method; 5) Experimental field harvesting, unhuled rice yielded around 65 kg or 30–40 kg of rice; and 6) Supervision during the experimental cultivation by IPB lecturers and village officials.

Abstract

Air bersih adalah air yang dapat digunakan untuk keperluan sehari-hari dan kualitasnya sesuai dengan peraturan pemerintah dan dapat diminum apabila dimasak. Untuk mengetahui kualitas air maka dapat dilihat dari higinitasnya menggunakan indeks Coliform atau Most Probable Number of Coliform Organisme (MPN) seperti peraturan menteri tentang kriteria  standar kualitas yaitu  PRRI No. 82/2001 that 1000 MPN/100 ml. Tujuan penelitin ini adalah untuk melihat kualitas air baku PDAM Makassar dengan melihat hadirnya bakteri pencemar dan mengidentifikasi bakteri kontaminan golongan  Enterobacteriaceae dari sumber air baku PDAM Makassar. Teknik sampling penelitian yaitu Purpose sampling. Sampel diperoleh dari sumber air baku Panaikang/Ratulangi, Bili-bili and Somba Opu menggunakan botol transport dan selanjutnya di bawa ke Laboatorium Biologi STKIP-PI Makassar untuk uji Mikrobiologi. Deteksi  jumlah bakteri Coloform dan Escherichia coli menggunakan metode MPN sesuai prosedur Waluyo yang meliputi uji penduga, uji penegas,uji lengkap dan pewarnaan gram. Hasil penelitian memperlihatkan bahwa nilai MNP Panaikang >1100 sel/100 mL sampel, Somba Opu 1100 sel/100 mL dan Bili bili 150 sel/100 mL sampel.
