Beberapa tahun yang akan datang dunia akan mengalami krisis bahan bakar minyak, dan salah satu alternatif bahan bakar yang dapat digunakan adalah alkohol fuel grade/etanol (Billah, 2009 : 24). Alkohol memiliki keunggulan bila dibandingkan dengan bensin karena angka oktan Alkohol sebesar 108 dan dapat bekerja pada rasio kompresi yang lebih tinggi(Muku & Sukadana, 2009 : 26). Pada umumnya penggunaan bahan bakar alkohol masih membutuhkan campuran bensin. Pada penelitian kali ini digunakan bahan bakar alkohol tanpa campuran bensin, bahan bakar ini disebut E â€“ 100 (100 % alkohol). Karena Eâ€“100(etanol/alkohol) memiliki nilai oktan yang lebih tinggi dari bensin, maka perbandingankompresi dan ignition timing mesin empat langkah harus disesuaikan (karena pada umumnya mesin sepeda motor empat langkah dirancang menggunakan bensin. Penelitian ini bertujuan untuk mengetahui pengaruh perbandingan kompresi dan ignition timingterhadaptorsi, daya dan Spesific Fuel Consumption (Sfc) Honda Vario 110 cc pada saat menggunakanÂ Eâ€“100. Variabel bebas pada penelitian ini adalahignition timing, dan variabel terikatnya adalah torsi, daya dan Spesific Fuel Consumption (Sfc). Penelitian ini menggunakan metode eksperimen, dimana terdapat perlakuan berupa : modifikasi padatonjolan sensor pengapian (Pick Up - Pulser/Triger) sehingga ignition timing dapatdivariasikan. Terdapat 8 (delapan) sampel ujicoba yaitu : sampel â€“ 1 (bahan bakar Pertamax 92, kompresi 10 : 1 dan ignition timing 15 ï‚°BTDC), sedangkan pada saat menggunakan E â€“100 perbandingan kompresi disetel 13 : 1 dantiming pengapian disetel 10 ï‚°BTDC (sampel â€“2), 15 ï‚°BTDC (sampel â€“ 3), 20ï‚°BTDC (sampel â€“ 4), 25ï‚°BTDC (sampel â€“ 5), 30ï‚°BTDC (sampel â€“ 6), 35Â°BTDC (sampel â€“ 7) dan 40Â°BTDC (sampel â€“ 8). Perbandingan kompresi13 : 1 dicapai dengan modifikasi pada kepala piston sehingga volume kepala piston menjadi 3,5 cmÂ³ (piston GM.1â€“54/50/13), dengan menggunakan piston ini tekanan silinder dapat mencapai 170 psi (11.95 kg/cm 2). Berdasarkan pengujian dan perhitungan, daya optimal diperoleh denganignition timing disetel 37,65ï‚°BTDC, sedangkan Sfc optimal diperoleh denganignition timing disetel 25,5ï‚°BTDC.Kata kunci : etanol, kompresi, piston, ignition timing, torsi, daya

An integrated system between cattle and oil palm plantation has a great potency for development of bioindustry, either in the form of animal feed or organic fertilizer bioindustry. Bioindustry of cattle feed is developed from biomass of plantations, such as stem and leaves of palm, palm kernel and solid. Bioindustry of organic fertilizer is developed from cattle manure. The targets of development of bioindustry are palm plantations in Sumatera and Kalimantan regions, covering 9.25 million hectares. It is estimated to be able to produce biomass quantity as much as 54.60 million tons per year which can be used as fodder for 12.13 million animal unit (AU) of beef cattle, whereas currently there are only 3.06 million AU cattle in Sumatera and Kalimantan, so the opportunities for the addition of cattle in both islands are 9.07 million AU. The existing beef cattle population of 3.06 million AU has the potency to produce 6.1 million tons of organic fertilizer can be used to fertilize 3.0 million hectares, therefore the rest of 6.25 million hectares remain unfertilised. The prospect of bioindustries on integration system of cattle with oil palm plantations in Sumatera and Kalimantan is very potential to meet the needs of organic fertilizer for plants and to utilize oil palm biomass for cattle feed. Key words: Bioindustry, biomass of oil palm plantation, cattle manure

The knowledge of probiotic spread widely, mainly after having been found some probiotics that can be used by animal. The result of research on the usage of some types of probiotics in rations of chicken give different influence on chicken productivity. Using probiotic starbio 0.25% in ration could increase the body weight of broiler up to 6 weeks of age and could increase the consumption of crude fibre up to 6% in the ration. Using probiotic starbio 0.25% in ration of layer could increase 19-26% eggs products and reduce feed conversion and water content in faeces and give additional income for the farmers as 44 up to 48%. Culture yeast as much as 0.2−0.3% is effective to add in rations of broiler 0−4 weeks of age. Lactobacillus acidophilus 2% and 4% in rations of layer may increase 5−11% of egg products and reduce feed conversion. It can be concluded that using probiotic in rations may increase the productivity of broiler, layer and native chickens. Key words: Probiotic, chicken diets, productivity of chicken

The optimal productivity of native chicken could be reached if reared on thermoneutral zone, a comfortable environment temperature. The comfortable environment temperature for the native chicken is still unknown, but it is predicted on around 18 to 25 °C. The native chicken placed on high temperature (25-31 °C) shows low productivity, including lower product and the weight of eggs, and also low growth rate. The decrease of egg number could reach 25% compared with those placed on comfortable environment temperature. The weight of 8 week-age ofnative chicken are also different i.e 257 g on high temperature, while on comfortable temperature could reach 427 g. This productivity decreased is mainly caused by the decreased of feed consumption, and also by the change of physiological condition of the chicken. The efforts to increase the native chicken production on high environment temperature are through selecting and crossing, manipulating environmental temperature, improving rearing management, and manipulating feedstuff and feed management. Manipulating feedstuff is the cheapest method, easy to do for increasing the amount of nutrient consumption. The method is by adding vitamine C, phosphor or giving sodium bycarbonate in the rations. The amount of vitamine C addition is 200-600 mg/kg ration on chicken producing eggs and 100-200 mg/kg ration to improve the chicken growth. Key words: High environment temperature, physiology, productivity, native chicken

Publisher : Indonesian Center for Animal Research and Development

The cacao farmers generally experienced problems on low cacao productivity and hence farmer’s income. The aim of this paper is to describe concept on the development of feed and organic fertilizer bioindustry based on cacao-goat integration to enhance productivity and farmer’s income. The potential cacao-goat integration covers 1.4 million hectares of cacao plantation and 7.8 million head of goats in nine provinces. Implementation of cacao-goat integration allows to use cacao biomass as feed for goats, and goat’s manure can be applied as fertilizer for cacao plantation. Bioindustry of feed is developed from 3.3 million tons biomass of cacao that consisted of 1.9 million tons of cacao pods and 1.4 million tons of cacao leaves. Bioindustry productions of solid and liquid organic fertilizer are 0.6 million tons and 344 million liters, respectively. The development of feed and organic fertilizer bioindustry is appropriate to improve cacao and goat productivities lead to increase farmer’s income.

Abstract. Reog is one of Indonesian art which is origin from Ponorogo, East Java. Barongan (dadak merak), the most dominant element of this art using the part of protected animals the green peafowl (Pavo muticus)’s feathers. In 2018, we do research to one green peafowl breeder and four “barongan” maker’s groups in Ponorogo District. Our research result found that to make single “barongan”, they need about 900-1200 feathers which is similar with 6-10 male green peafowl. Our data also shows that every groups produce about 20 “barongan” in every year. The only one green peafowl breeder in Ponorogo who has 12 adult male only can supply for one maker group. So, if we want to make reog ponorogo recognized as a world heritage, we need 20 green peafowl breeders which have 6-10 adult male individual.

Basically treatment is preoperative patient care, intra and postoperative surgical cases. In postoperative care there is currently a technical problem that remains unanswered, namely heating the bed postoperatively. Implementation of early mobilization, effective coughing, relaxation still requires effective participation of nurses and patients are sometimes ignored because it is too time consuming and nurses. Heating the bed according to the researchers seems to be the solution above. The purpose of this study was to determine the effect of bed temperature on the speed of recovery of body function (peristaltic / platinum movement) using quasi experimental research methods to approach post control design, with a sample of 15 groups of 15 control treatment groups, sampling with simple random sampling technique, research done in the Inpatient Room of Bogenvil Ngudi Waluyo Wlingi Hospital. The results obtained by the t test, t is 3.24 are greater than t table. In conclusion there is a significant effect of bed temperature on postoperative speed of body function (peristaltic / platelet movement) recovery. This evidence should be an encouragement to manage the implementation of surgical care for habits.
