Abstract

Utilization of local resource (Neptunia plena L. Benth and Leersia hexandra Swartz) as feed ration for buffalo fattening could make cost efficiency, fulfil primary life needs and production. The objectives of study is to determine the Dry Matter Digestibility (DMD), Organic Matter Digestibility (OMD), NH3 ruminant fermentation and Volatile Fatty Acid (VFA). The conduct of the study was in Laboratory of Animal Husbandry Nutrient Science, Faculty of Animal Science and Agriculture, Diponegoro University, Semarang by using in vitro method with a Complete Randomized Design (CDR) of five treatments and five replicates: (1)  T1 =100% Leersia hexandra Swartz; (2) T2 = 100 % Neptunia plena L.Benth; (3) T3 = Ration (15% Neptunia plena L.Benth + 15% Leersia hexandra Swartz + 70% other feedstuffs); (4) T4 = Ration (20% Neptunia plena L.Benth + 20% Leersia hexandra Swartz + 60% other feedstuffs); and (5) T5 = Ration (25% Neptunia plena L.Benth + 25% Leersia hexandra Swartz + 50% other feedstuffs). Data analysis used analysis of variance with a significance level of 95% and then followed by Duncan Multiple Range Test (DMRT). The results showed that T3 and T4 treatments produced the highest DMD at (P <0.05), i.e. 43.65% and 43.26%, respectively. T2 treatment (47.66%) significantly produced the highest OMD (P <0.05) compared to T4 (46.81%) and T1 (45.36%). T5 treatment (5.28 mM) significantly produced in the highest NH3 (P <0.05) compared to T2 (4.88 mM); T3 (4.73 mM); and T1 (4.43 mM). T5 treatment (145.4 mM) significantly produced the highest VFA (P <0.05) compared to T4 (140.0 mM); T3 (135.4 mM); T2 (134.8 mM); and T1 (123.6 mM). In vitro digestibility and fermentation ruminant of buffalo ration based on Neptunia plena, L. Benth, and Leersia hexandra Swartz as local resources can buffalo improved ruminant fermentation so that it is capable of increasing the buffalo productivity.

Abstract

Ruminants have a complex digestive system so they can utilize forage nutrients to convert them into food products of high economic value (meat and milk) and papaya leaves have the potential to be an alternative source of new feedstuff.  The research was conducted at the Laboratory of Animal Feed Chemistry, Faculty of Animal Husbandry, Hasanuddin University Makassar (for proximate analysis), Laboratory of Animal Nutrition and Feed, Faculty of Animal Husbandry, Gadjah Mada University, Yogyakarta (for quantitative and qualitative analysis).  The study was used proximate analysis to determine the nutritional content of papaya leaf, in vitro analysis to measure dry matter digestibility (DMD) and organic matter digestibility (OMD), and Thin-Layer Chromatography (TLC) for quantitative and qualitative tests of alkaloid compounds.  The results showed that the DMD values of dry leaf and fresh leaf DMD were 72.74% and 78.44%, respectively. The highest score of rations DMD and OMD was R2FPL (69.98%) and R2DPL (61.92%), respectively.  A qualitative test of papaya leaf bioactive compounds using UV 254 light obtained 3 spots with a detectable Rf value of 0.72 and a quantitative test with piperine test parameters showed the results of the analysis were "not detected".  The results showed that papaya leaves were suitable as an alternative feedstuff for ruminants (cattle, buffalo, goats, and sheep).

Abstract

Consumers’ preferences for beef are influenced by the interplay of intrinsic and extrinsic attributes, which affect their purchasing decisions and willingness to pay. Therefore, this study aimed to identify the key attributes influencing consumers’ purchasing power for beef in both traditional and modern markets in Samarinda City. The research was conducted in various markets in Samarinda City, East Kalimantan Province, including traditional markets (Segiri, Ijabah, Kedondong, and Rahmat) and modern markets (Hypermart Bigmall, Farmers Market Mall SCP, Foodmart Mall Lembuswana, and Lotte Grosir), using a questionnaire-based interview method. A total of 80 respondents, comprising 51 women and 29 men, were selected through purposive sampling. Primary data were collected through interviews and questionnaire responses. These were analyzed using chi-square tests and descriptive methods to assess consumers’ preferences for beef product attributes. The results showed that consumers in both traditional and modern markets preferred dark red beef with low-fat content and classified as Group One commercial cuts. The dark red beef with low-fat content is perceived as fresher and healthier (due to the lower number of calories and higher protein levels). The chi-square analysis indicated significant differences in consumers’ preferences for beef attributes between traditional and modern markets in Samarinda City, East Kalimantan Province.

Abstract

Financial analysis is an activity of assessing and determining rupiah units on aspects that are considered feasible from decisions made in the business analysis stage, and the results of the analysis are used as basic parameters in determining the feasibility of a business. The objective of this research was to determine the financial feasibility of the beef cattle fattening business in Balikpapan city. The study employed a survey method within the North Balikpapan subdistrict, in which 40 respondents were selected through purposive sampling. Criteria for respondents included ownership of at least two beef cattle with a rearing period exceeding one year. The financial feasibility analysis used several key indicators, including the break event point (BEP), net present value (NPV), benefit cost ratio (B/C ratio), internal rate of return (IRR), and payback period (PP). Based on the study calculations, the BEP was IDR 9.676.911; NPV (9.15%) was IDR 1.017.779.514; NPV (14.15%) was IDR 952.403.118; B/C ratio was 2.7; IRR was 87%; and PP was 0.37 years. According to these results, it could be concluded that the beef cattle business in the North Balikpapan subdistrict, Balikpapan city, was feasible.
