Efektivitas Komik Saku Sebagai Media Pemilih Dan Pemilu Bagi Perempuan Marginal

Women’s participation in politics is very low particularly because of the situation in which women are marginalized both in terms of voters and candidates. In this sense, voter education based on gender perspective is one of the significance ways to increase women’s political awareness. Pocket comic is seen as a media that can be used to achieve such awareness. This study examines the effectiveness of comic as an aid used in voter education in order to increase political participation of women as evaluators. This study found that pocket comic could be well understood by married women who received information from the media. Those women had also been trained by the Government and the PKK in the elections training through which they were stimulated to have gender awareness and then internalize it in their life

In Vitro Digestibility of Ration Containing Different Level of Palm Oil Frond Fermented with Phanerochaetae chrysosporium

Phanerochaete chrysosporium was widely used to delignify agricultural waste product and improve biodegradation of the substrate as animal feed.  The experiment was carried out to increase the use of palm oil fronds as a substitute material for napier grass through biodegradation process with P. chysosporium. A completely randomized design with four treatments and four replications was used. The treatments were ration containing 60% napier grass (R1), ration containing 40% napier grass and 20% fermented palm oil frond (R2), ration containing 20% napier grass and 40% fermented palm oil frond (R3), ration containing 60% fermented palm oil frond (R4). Fourty percent concentrate was included in all treatment rations. Parameters measured were in vitro digestibilities of dry matter, organic matter, crude fiber, NDF, ADF, NH3, TVFA, and ruminal cellulolitic bacteria. Results showed that increasing level of fermented palm oil frond in the ration reduced (P<0.05) digestibilities of dry matter, organic matter, crude fiber, NDF, ADF, N-NH3, TVFA concentration and number of ruminal cellulolytic bacteria. It is concluded that fermentation of palm oil frondwith P. chysosporium decrease lignin content by 47.79%, but increasing the fermented palm oil frond in the ration reduces nutrient digestibilities, N-NH3 and TVFA concentrations and rumen cellulolytic bacteria counts. Fermented palm oil frond up to 40% could be used as a substitute for forages in ruminant rations

Rumen Fermentation and Milk Quality of Dairy Cows Fed Complete Feed Silages

This study was conducted to evaluate the rumen fermentation and milk quality of Friesian Holstein (FH) cows given complete feed silages during lactation. Twelve FH cows in 5th mo lactation were offered four dietary treatments in a completely randomized design with three replications. The treatments were, control diet (NS) containing 50% concentrate, 45% elephant grass and 5% sun flower meal; grass complete feed silage (GS) containing 50% concentrate, 45% elephant grass and 5% sunflower meal; rice straw complete feed silage (RSS) containing 50% concentrate, 30% elephant grass, 15% rice straw and 5% sunflower and palm oil frond complete feed silage (PKS) containing 50% concentrate, 30% elephant grass, 15% palm oil frond, and 5% sunflower meal. Ensilage was done with addition of Lactobacillus plantarum 1A-2 and cellulase enzyme. Analysis of variance and Duncan test were applied to compare the different among the means of treatments. Complete feed silages had range of pH between 3.89-4.44, temperature of 28.0-29.67 oC and lactic acid bacteria of 0.54-1.50 x 108 cfu/g. Crude protein intake of  RSS was  the highest among treatments. Acetate concentration in rumen liquor was more than 70%. Milk yield and protein were not different among treatments. GS gave the highest milk fat (5.66%). The conclusion was that both complete feed silages, using rice straw or palm oil frond can be used as alternative rations for lactating dairy cows. Key words: complete feed, silage, Friesian Holstein, palm oil frond, rice stra

Methane Mitigation and Microbial Diversity of Silage Diets Containing Calliandra calothyrsus in a Rumen in Vitro Fermentation System

This study was conducted to investigate the effects of silage based diets on methane (CH4) mitigation and microbial diversity in a rumen in vitro fermentation. The experiment was arranged in a completely randomized design with five treatments and three replications. The dietary treatments consisted of varying levels of silage containing 50% Calliandra calothyrsus as follows K; 100% concentrate + pure tannic acid of 1 mg/mL, R1; 25% silage + 75% concentrate, R2; 50% silage + 50% concentrate, R3; 75% silage + 25% concentrate, and R4; 100% silage. The fermentation variables measured were total gas, CH4, in vitro organic matter digestibility (IVOMD), VFAs, pH, N-NH3, number of protozoa, and microbial diversity analysis. Increasing level of silages reduced total gas production, CH4 concentration, IVOMD, index of bacterial diversity, protozoal number, total methanogens and Methanobacteriales population. Diet with 25% to 50% silage decreased CH4 concentration, total gas production and IVOMD by 11.43%, 24.92%, and 18.73%, respectively. Ammonia N and VFAs (except butyrate and valerate) were significantly reduced (
