The study about “Evaluation of semi organic system on rice production at fifth plant season” whose purpose to evaluate the quality and rice yield at semi organic system at fifth plant season, its impact on soil chemistry properties and its properness to farmers. This field experiment has been conducted from May to September 2008 at Palur, Sukoharjo, with two factors. The first factor is anorganic fertilizer at recommendation dose (Urea 300 kg ha-1, ZA 100 kg ha-1, SP-36 150 kg ha-1, KCl 100 kg ha-1). The second factor is 30% of dose recommendation anorganic fertilizer (Urea 100 kg ha-1, ZA 30 kg ha-1, SP-36 50 kg ha-1, KCl 30 kg ha-1) and five tons organic fertilizer. The data was analyzed with T test to evaluate the differences of semi organic system and anorganic system. The experiment’s result shows that the semi organik system gives weight of dry straw which is higher than anorganic system. The yield of dry unhulled rice in semi organic system(9,2 ton/ha) isn’t significantly different from the weight which is compared with anorganic system (8,576 ton/ha). From the economic analysis, semi organic system gives higher profit than anorganic system. The rice quality (dust and fiber contain) in semi organic system is higher but protein contain isn’t different. Semi organik system gives organik matter contain (1,618%), KPK (14,454 cmol/kg), N total (0,368%), available P (0,368 ppm) and available K (164,96 me%) which is signiificantly higher but givew lower pH (5,5) than anorganic system.

Publisher : Universitas Sebelas Maret

Pakan merupakan faktor yang sangat penting dalam usaha pengembangan peternakan. Ternak ruminansia (sapi, kerbau, kambing dan domba) pakan utamanya adalah hijauan. Kualitas hijauan yang tinggi dalam jumlah yang cukup diperlukan untuuk mendukung produksi yang optimal.Ketersediaan pakan hijauan dalam mendukung produksi sering mengalami kendala yakni oleh karena tidak terjaminnya kontinyuitas produksi hijauan maupun adanya zat anti nutrisi di dalam hijauan tersebut. Daun ubikayu merupakan limbah pertanian yang memiliki potensi (kuantitas dan kualitas) sebagai pakan ternak. Namun dalam penggunaannya terdapat faktor pembatas karena kandungan asam sianida (HCN)-nya.Pengaruh (efek) negatif (toxoc) HCN dapat dikurangi dengan cara menurukan kandungan HCN dalam daun ubikayu tersebut dengan jalan mengangin-anginkan/melayukan dan atau penjemuran, atau dapat pula dilakukan dengan cara menambah senyawa atau asam amino yang mengandung sulfur mserta vitamin B12 dalam pakan/ransum.

Emergency food is needed when a disaster occurs. Emergency conditions encourage the provision of food that is ready to eat with sensory properties that can be accepted by the community, has sufficient nutrient content to meet the body's caloric needs and is resistant during storage. This study aims to obtain the best formulas of the food bar based on the parameters observed, namely sensory, chemical, total caloric, and aw as well as its shelf life estimation with the Accelerated Shelf Life Test. Food bar was made from white millet flour and fish koya that was made from snakehead fish and soy flour. Intermediate moisture food (IMF) applied in this study with the initial formulation was determined using mass equilibrium. The effectiveness test was used to determine the best formula based on all observed parameters. The results showed that the best food bar formula was formula F2, which has a chemical composition consisting of moisture content (20,99±0,21%); ash (3,45±0,35%); fat (18,10±0,13%); protein (12,24±0,28%); and carbohydrates (45,22±0.32%), aw (0,76±0,01); and total calories (per 50 g) was 232,04±1,96 kcal. The shelf life of food bar F2 was 19 days. Based on the results obtained, the total calories produced from the best formula have not met emergency food calorie standards.
