Kecukupan ketersediaan pangan dalam jumlah dan mutunya merupakan aspek penting dalam mewujudkan ketahanan pangan nasional karena dapat memperbesar akses bagi penduduk untuk memperoleh pangan. Angka kecukupan ketersediaan energi dan protein dengan skor mutu pola pangan harapan yang dianjurkan dalam Widyakarya Pangan dan Gizi ke VI tahun 1998 menjadi indikator penilaian aspek ketersediaan dari ketahanan pangan nasional.Keragaman ketahanan pangan dengan indikator rata-rata ketersediaan jumlah gizi per kapita per hari tergolong sangat kuat yang ditunjukkan oleh perbandingan ketersediaan dengan angka kecukupan konsumsi energi melebihi 45 persen sedangkan protein melebihi 67 persen. Namun ditinjau dari mutu pangannya, belum mencapai mutu pola pangan harapan yang ditunjukkan oleh masih rendahnya sumbangan buah, sayur dan pangan hewani dalam ketersediaan pangan dan gizi.Dukungan impor telah meningkatkan ketersediaan dan memperkuat ketahanan pangan nasional tetapi mengandalkan peningkatan ketersediaan dari peningkatan produksi pangan dalam negeri akan lebih aman dan lebih berpihak kepada kelangsungan usaha petani produsen pangan yang umumnya berskala usaha sangat kecil dan berpendapatan rendah

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan UMMB Plus terhadap performan/tampilan produksi kambing PE jantan. Materi yang digunakan adalah kambing PE jantan sebanyak 15 ekor yang dibagi dalam tiga macam perlakuan dan lima ulangan. Adapun perlakuan yang diberikan adalah P0 (60 hijauan), P1 (hijauan + konsentrat), dan P2 (hijauan + UMMB Plus). Parameter yang diamati meliputi konsumsi pakan, pertambahan bobot badan harian (PBBH), konversi pakan, dan feed cost per gain. Data konsumsi, PBBH dan konversi pakan dianalisis variansi Rancangan Acak Lengkap (RAL), sedangkan untuk feed cost per gain diperoleh secara deskriptif. Hasil penelitian menunjukkan bahwa rata-rata dari ketiga perlakuan yaitu P0, P1, dan P2 berturut-turut untuk konsumsi bahan kering harian (kg) 0,42, 0,86, dan 0,63, PBBH (kg/hari) 0,01; 0,05; 0,02, konversi pakan 42,00, 17,28, dan 31,62. Sementara untuk feed cost per gain (Rp) 52.500,00, 30.282,21, 91,327,21. Hasil analisis variansi untuk konsumsi BK, PBBH, dan konversi pakan menunjukkan adanya perbedaan yang nyata. Kesimpulan dari hasil penelitian ini adalah penggunaan pakan supplemen UMMB Plus memberikan tampilan produksi kambing PE jantan yang lebih baik disbanding pemeliharaan dengan pakan hijauan, akan tetapi lebih rendah disbanding penggunaan konsentrat.

This experiment was conducted to investigate the efficacy of methyl groups donor of betaine to spare methionine based on performance and carcass in broiler chickens. In total, 100 day old broiler chickenss were used in this experiment. They were allocated to 4 dieaty treatmants in 5 replicates with 5 broilers each. The basal diet was deficient in methionine. The control diet was obtained from basal diet supplemented with methionine to meet the requirements 5 g/kg diet for starter period and 3.8 g/kg diet for finisher period. The rest 3 treatments were basal diet deficient in methionine supplemented with 1, 2 and 3 g betaine per kg diet. The variables that were observed included average daily gain and carcass characteristics. The data were than analyzed by analysis of variance of Completely Randomized Design and continued with Dunnet test. The result indicated that supplementation of 1 and 2 g betaine per kg diet deficient in methionine resulted the broiler performance which was not different with supplementation of methionine. Accordingly, carcass characteristics for broilers fed diet supplemented with methionine were not different with that supplemented with betaine, which indicated that betaine may reduce the methionine level in the broiler diet. It can be concluded that betaine spares metionine in broiler diets.

This research aims to explain in detail about the condition of Gapoktan institutional through activities of Reinforcement of Society Food’s Distributive Institution (Reinforcement-LDPM) at the Regency of Grobogan considered from superstructur aspect, community profiles of farmers the member of Gapoktan, and organizational profile aspect of the Gapoktan. Qualitative method and descriptive approach were used in this research. The sampling was snowball sampling technique. The technique of data collection used visceral interview, observation, and record-keeping. The tryout of data validity used triangulation source and triangulation method, whereas the data analysis used three main components, i.e. (1) data reduction, (2) data display, and (3) drawing conclusion and verification. Based on the research result, it can be concluded that analysis of Gapoktan institutional considered from superstructure aspects including government policy which influenced Gapoktan institutional. Both the federal government and local government of Grobogan Regency have issued some policies that support the reinforcement activities of Society Food’s Distributive Institution (LDPM), but the government policy about Bulog standardization was considered that it was too difficult for Gapoktan institutional. Considered from community profile, the development of Gapoktan institutional has transpired well enough because of having sufficient asset, collective action in both of routine meeting and directive counseling, drawing conclusion by the chief of Gapoktan through discussion and coordination focus, whereas the relationship between Gapoktan institutional with the other Gapoktan has transpired well. Considered from its institutional profile, the Gapoktan still had constraints or problem. Looking to its organization system, the structure of labor units of the reinforcement activities of Society Food’s Distributive Institution (LDPM) had not been organized well. The members prefer to profitable jobs than the voluntary Gapoktan. Outsides, the institutional management and resource allocation had not well complied.

So far, development of rural agribusiness institutions is commonly far from expectation to solve related problems. The model of partnership between farmers and agribussiness entrepreneurs indicated an unsatisfactory performance. The underdevelopment of the partnership’s model was due to philosophically, it had not united stakeholders within a common purpose which provided benefits proportionally. The objective of the research aimed at (i) describing the local agribussines institution having potential to suppot a carrot agribussiness; (i) to assess the local institutional performance in order to support a carrot agribussiness; (ii) to examine the opinion of its stakeholders towards institutional development for carrot. This study used a descriptive method. The location have been selected purposively. The Subdistrict of Tawangmangu had been selected as the produce of carrot was the highest compared to other subdistricts in District of Karanganyar. The information was collected from a number of key informants. The informants get confused about the concept of ‘agropolitant itself; even some of the farmers did not care about that concept. Area of agropolitant which formerly planned to become agro-tourism and the promotion of the local product was regarded far from expectation. In fact, there was no marketing activities for those local products. Some programs was considered to be reasonable to implement in order to achieve the objectives. First, in order to improve the bargaining positions, it was reasonable to increase the intensity of asssistance. Particularly, it was suggested to increase the quality of organization management and entreprenurship. Second, it is necessary for the local government to facilitate the networks among the subdistricts or with outer districts with special attention to connect the carrot farmers. As the institution which is commodity base is effective for implementing the function of development, advocation, and promotion relevant to carrot. Third, there is necessary for local government to improve the effectiveness, especialy at the stage of socialization, in regard with the agropolitant development.
