Biannual bearing fruit is a common phenomenon in tropical fruit trees. However, effectiveness of flowering induction on those fruits is still lack of study. The ojective of the research was to study the effectiveness of flowering induction on pummelo of different fruit load on previous year. Field experiment was conducted at farmer's orchad Bantarmara village, Cisarua, Sumedang Region, West Java (300 m above sea level) from August 2007 to April 2008. Experiment was carried out using Completely Randomize Block Design. Experiment was combination of high crop load and less crop load with strangulation position at main stem and primary branches. The results showed that crop load of previous year (higher and less) with strangulation position at primary branches had significant response to the number of flower clusters, flower buds, bloming flower, fruits formed, and fruit sets as compared to control, when strangulated at primary branches. Nevertheless, amount of fruit sets, level of greenness leaf and leaf area seened were not determined by fruit load non position of strangulation. This finding implies that fruit load management is an important factor in determining the success of flowering induction using strangulation. Key words: fruit load, strangulation, pummelo, flowering induction

AbstractThe research of grafting methyl methacrylate (MMA) onto Cyclic Natural Rubber (CNR) has been carried out. Benzoyl Peroxide (BPO) was used as a inisiator and temperature condition at 90oC with variation of time 1 and 2 hours. Grafting process was done with technique of reflux in a tree-neck flask with condenser and oil bath. Spectra analysis FTIR performed for determine the presence of grafted MMA on the backbone of CNR. The results showed that the product CNR-g-MMA was formed with the marked appearance of the absorption peak wave numbers at 1731 and 1730 cm-1 (carbonyl group absorption) typical for carbonyl (C = O) of metal methacrylate. The degree of grafting increased with the increasing time grafting.Keywords: grafting, cyclic natural rubber, mathylmetacrilate, benzoyl peroxide

Penelitian bertujuan untuk mengkaji dan mengevaluasi dinamika bobot badan sapi potong serta potensi ketersediaan pakan pada musim kemarau di Kabupaten Merauke. Lokasi yang dipilih adalah tiga distrik yang mewakili pusat pengembangan sapi potong di Merauke dan distrik tersebut memiliki kepadatan ternak atau populasi yang tinggi dan dibandingkan antar-luas wilayah, sehingga yang mewakili populasi tinggi (Distrik Merauke), sedang (Distrik Tanah Miring), dan rendah (Distrik Kurik). Metoda menggunakan survei melalui penimbangan ternak sapi yang dipelihara petani/peternak dengan jumlah ternak 50 hingga 100 ekor, terdiri jantan dewasa, induk, muda, dan anak. Untuk mengukur produksi hijauan pakan dibuat kurungan terbuat dari kayu ukuran 1,5 x 1,5 meter sebanyak 15 buah terbagi dalam tiga lokasi, masing-masing lokasi terdapat lima kurungan. Hasil: rataan bobot badan ternak sapi di ketiga Distrik (Merauke, Kurik dan Tanah Miring), sangat rendah baik itu pedet (< 0,3 kg/ekor), ternak muda maupun dewasa (< 0,2 kg/ekor); variasi spesies hijauan dan legum di lokasi pengamatan relatif sama dan didominasi oleh spesies rumput (93,30 – 94,85 persen), dan produksi hijauan pada awal musim kemarau (bulan Juli) masih relatif tinggi, dan terus menurun sampai puncaknya pada bulan September dan Oktober
