Abstract

ABSTRAKTeknologi kapas hibrida merupakan salah satu upaya untukmeningkatkan produksi kapas nasional. Sampai saat ini belum tersediavarietas kapas hibrida nasional untuk program pengembangan kapasnasional. Penelitian ini bertujuan mengetahui ratio galur (A line) manduljantan dan galur pemulih kesuburan (R line) yang optimum untukmenghasilkan benih hibrida kapas paling tinggi dengan cara persilanganalami. Penelitian dilaksanakan di Kebun Percobaan Pasirian-Lumajang,Jawa Timur mulai Januari sampai Desember 2011. Percobaan ini terdiridari satu pembanding T1 dengan penyerbukan manual dan 5 perbandinganratio (A line : R line) yang berbeda, yaitu T2 (3:2), T3 (4:2), T4 (5:2), T5(6:2), dan T6 (7:2) dengan penyerbukan alami. Perlakuan disusun dalamRancangan Acak Kelompok (RAK) diulang 3 kali dengan luas petakmasing-masing perlakuan 25 m x 5 m. Benih kapas ditanam dengan jarak125 cm x 25 cm. Pupuk yang diberikan sebanyak 300 kg pupuk majemuk(15 N:15 P 2 O 5 :15 K 2 O) dan 100 kg pupuk Urea/ha. Hasil penelitianmenunjukkan bahwa perlakuan penyerbukan manual (T1) menghasilkankapas berbiji sebanyak 1023 kg/ha, nyata paling tinggi dibandingkanperlakuan dengan penyerbukan alami. Terdapat korelasi positif yangsangat nyata antara hasil kapas berbiji dengan jumlah populasi (r =0.75967). Hasil kapas berbiji tidak berbeda pada perlakuan T2 sampai T6yang bervariasi antara 377- 452 kg kapas berbiji/ha, dengan efisiensipenyerbukan alami sebesar 37–45%. Untuk produksi benih hibrida denganpersilangan alami dapat digunakan ratio 7 baris tetua betina dan 2 baristetua jantan (perlakuan T6). Harga benih hibrida kapas yang dihasilkandengan cara penyerbukan alami sebesar Rp. 98.571,-/kg sedangkan dengancara penyerbukan manual sebesar Rp. 101.826,-/kg.Kata kunci: Gossypium hirsutum, mandul jantan, pemulih kesuburan,penyerbukan manual, penyerbukan alamiABSTRACTHybrid cotton technology is an attempt to increase the nationalcotton production. Hybrid cotton varieties is not yet available for thenational cotton development program. This study was aimed atdetermining optimum ratio of male sterile lines (A line) and restorers (Rline) lines for producing high hybrid cotton seed yield. The experimentwas conducted in the Experimental Garden Pasirian-Lumajang, East Javafrom January to December 2011. This experiment consisted of T1 withmanual pollination (control), and 5 different ratios (A line : R line) withnatural pollination namely T2 (3:2), T3 (4:2), T4 (5:2 ), T5 (6:2) and T6(7:2). Treatments were arranged in a randomized block design (RBD) with3 replications, plot size was 25 m x 5 m of each. Seeds were sown witha distance of 125 cm x 25 cm. Fertilizers given were 300 kg of compoundfertilizer (15 N: 15 P 2 O 5 : 15 K 2 O) and 100 kg Urea /ha. From this researchit was found out that the T1 treatment by manual pollination produced asmuch 1023 kg seed cotton yield / ha, was the highest compared to naturalpollination treatments. There was high correlation between seed cottonyield and plant population (r = 0.75967). Seed cotton yield of T2 to T6treatments was not significantly different, which varies between 377-452kg/ha, with natural pollination efficiency of 37-45%. Therefore, for cottonhybrid seed production based male sterility by natural crossing, 7 rows offemale lines and 2 rows of male lines ratio (treatment T6) can be used.Price of cotton hybrid seed by natural pollination as much as Rp. 98,571, -/kg while by manual pollination as much as Rp. 101, 826, - /kg.Key words: Gossypium hirsutum, male sterile, restorer, manual pollination,natural pollination

Abstract

Until now, the development of the environmentally sound micro-scale dairy cattle business (USPSMWL) in the District of Sagalaherang and Ciater of the Subang Regency not fully reached the desired level yet. The growth of the dairy cow population of about 1% per year is still below the national growth of 1.29%; beside that, the environmental quality of some of the business of dairy cows (USP) is still not good yet. Results from the survey showed that most location of the cow shed was placed < 5 meters of residential houses. By the end of 2010, more than 80% dairy cow waste has not well managed, so it could be risk factors: air pollution,public health problem and odor. This study was intended to findstrategiesfor developing USPSMWL in Subang Regency. This study has used a method based on the analysis of Analytical Hierarchy Process (AHP). Respondents of this study were 6 experts,  drawn from banking sector, animal husbandry sector, Dairy Milk Cooperative of Northen Bandung (KPSBU), Cooperative sector, Regency Government, and Environment sector.Theresults show that  the ?first priority actor? in the development USPSMWL in Subang Regency is ?The Government of Regency, District, and Village ?; the ?first priority factor? is ?The readiness of the community?, the ?first priority objective? is ?The increasing community income?; and the ?first priority strategy? is ?The increasing readiness of the community/farmers to conduct the business of dairy farming (USP)?. Based on experts opinion in AHP, it can be concluded that the role of the Government of the Regency/District/Village in the development of USPSMWL in Subang Regency is the primary importance. The main strategy to be implemented is ?to increase the community/farmers? readiness to conduct dairy farming business (USP)?. It is matched with the real needs of communities in the location of the USP included  (a) the need for increased knowledge and positive attitude of ?non-dairy farmers? and ?dairy farmers? community; (b) the need for capital support or procurement of production means for dairy farming, and (c) the need for increased motivation of the people to develop USPSMWL.

Abstract

Shrimp agro-industry is one of the food processing industries, which converts raw shrimp into high-value shrimp processed products. The production system used in shrimp agroindustry to respond market demand is a hybrid make to stock (MTS) and make to order (MTO). The decision to determine which products will be stored as supply sources and which products are made to fulfill orders is a critical decision that must be made on the MTS-MTO hybrid system. The concept of customer order decoupling point (CODP) is used to identify material flow points that connect a product with different consumers. This study aims to present a conceptual model in the MTS-MTO hibrid system based on customer order decoupling point (CODP) which is adjusted to product characteristics, production characteristics and market characteristics in the shrimp agroindustry. The results of the study are presented in a business process model template that describes the order of decisions for storing products or making products to fulfill orders and conceptual models in the form of diagrams named the CODP conceptual model on shrimp agroindustry.
