Abstract

Natural farming is an agricultural system that does not use external inputs in the implementation of its farming. This study aims to determine the level of participation of farmers at each stage of planning and decision making, evaluation and utilization of results. The research method uses a qualitative case study method. Data collection uses the method of triangulation methods, namely in-depth interviews, observation and focus group discussions. Key informants included the SRSC founder, chairman, active members and new members. The results showed the level of participation of farmers at the planning stage is at the level of self-participation where farmers decide themselves willingness to participate in natural farming activities. In addition, farmers plan their farming according to the resources they have and are guided by SRSC instructors. At the implementation stage, farmers carry out natural farming independently and are guided by extension workers or other farmers who have already done natural farming first. At the evaluation stage, the farmer evaluates every activity that has been carried out. Evaluation is not only at the end of the activity, but at the time of the activity, the farmer also conducts an evaluation together with more advanced farmers. At the yield utilization stage, farmers' income increases and the ability of farmers to do natural farming continues to increase as they become increasingly involved in activities in SRSC.

Abstract

Meat needs (Broilers) have increased and meat consumption is influenced by consumer preferences caused by shifting consumption patterns, and is supported by low prices compared to beef.  The shift is influenced by prices, substitute goods, tastes, season, age, education, number of dependents, income, and increasing population so that preferences, and attributes that consumers consider in buying broiler meat in traditional markets need to be studied.  The study used a purposive sampling method, with the criteria of the Adji Dilayas Sanggam Market,  Senja Market, and the Milono Market in Berau Regency, having broiler meat traders.  Determination of respondents using proportional sampling techniques, each market 12 respondents (36 respondents), meet the smallest number of traders considered to meet the minimum sample criteria.  Sources of data obtained from primary data and secondary data.  The results showed that broiler meat that has a golden color, clean skin, medium carcass size, physically not bruised, fresh meat, and especially the chest.  Chi Square analysis showed that all attributes were significantly different (p <0.05), meaning that there were differences in preferences for the attributes of broiler meat in traditional markets.  Fishbein Multiatribute Analysis proves that meat freshness, flesh color, carcass physicality, skin cleanliness, carcass size, and carcass portion are the most considered, and or not considered attributes.

Abstract

Dwarf Napier grass (Pennisetum purpureum) is considered to be more suitable as forage for ruminants due to its high yield and nutritive value, but there is limited research on rabbits. Thus, the aim of this study was to investigate the effect of replacing concentrate with dwarf Napier grass on intake, gorwth performance and carcass composition of growing rabbits. Twelve growing rabbits were randomly distributed into three dietary groups in a completely randomised design: (i) concentrate feed ad libitum as control diet (T1), (ii) half of the control diet plus dwarf Napier grass ad libitum (T2), and (iii) quarter of the control diet plus dwarf Napier grass ad libitum (T3). The results showed that diets had a significant (p<0.05) effect on intake, growth performance and some non-carcass components. Rabbits fed T3 diet showed significantly (p<0.05) lower total DM intake than those fed T1 and T2 diets. Similarly, rabbits fed T3 diet showed significantly (p<0.05) lower total weight gain and daily weight gain than those fed T1 diet, but the respective values of those fed T2 diet were non-signifiacntly different from those fed T1 and T3 diets. There was significant effect on weights of meat with bone, fat, pelt, head and kidney by the diets, whereas weights of most of the non-carcass components were similar among the groups. In conclusion, diet consisting of half of the concentrate and dwarf Napier grass ad libitum is recommended to be used as it may reduce the feed cost compared to diet consisting of the concentrate alone.

Abstract

Infertile egg generally only be industrial waste hatching so that the necessary efforts to improve its quality. This can be done by processing. One of them  is a chips product, the product resembles a thin plat, small and solid. This studies aim to determine the physicochemical quality of egg chips. The study used a completely randomized design  factorial pattern 3x3. Factor A was the type of filler including soy powder, tapioca  powder, and a combination of both. Factor B is filler level (%) 0, 3 and 6. The parameters are testing of hardness, friability, solubility and moisture content. The results showed that the types of filler had a very significant effect (P <0.01) on dissolution time. Addition of filler level significantly affected (P <0.05) on hardness, friability and solubility. There is an interaction between types and levels of filler material against hardness and solubility. The addition of tapioca powder at the level of 3% in making egg chips can  be increasing hardness, not fragile, solubility time of  fast.  But the egg chip does not experience changes in water content.

Abstract

A polled Bali Cattle, or a naturally hornless cattle breed was first recognized in the early 1980s in Sidendreng-Rappang (Sidrap), south Sulawesi, where Bali cattle (Bos sondaicus) herd were mixreared with some Brahman cross (BX). Whereas BX is the result of a cross between a Brahman cattle and the Hereford or shorthorn (Bos Taurus) breed on a commercial ranch in the region. As such a variant is considered as having high productivity trait advantages and/or as even possibly becoming a superior cattle breed of choice being able to develop by the University of Hassanuddin, various researches had been carried out since 1985. To date, the research works had resulted in some findings, however, there might have only been up to preliminary stages so far. Vast and thorough investigations on productivity traits of the polled Bali cattle (PBC) variants are being sought. Currently, a science and technology-based local cattle breeding industry development program at the Maiwa breeding center, Faculty of Animal Husbandry, Hasanuddin University has been carrying out serial studies on genetic profiles of the variants, and also on their growth control and adaptation genes. The genes have been targeted for use as marker-assisted selection (MAS).

Abstract

The cocoa pulp is a slimy layer that surrounds the pieces of seeds, consisting of part of water and a layer of nutritional components which is quite high, including sucrose, glucose, and a little starch. The cocoa pulp, the by-product of cocoa production, has been used to avoid environmental pollution as an organic fertilizer. However, for livestock feed, the information is so limited. Therefore, the objective of this study was to determine the performance of male Bali cattle at different ages by feed concentrate containing cocoa pulp. The experiment was carried out in a completely randomized design consisting of 3 treatments and 3 replications so that it needed 9 male Bali cattle. The treatment consisted of A1 = male Bali cattle 2 years; A2 = male Bali cattle age 3 years; and A3 = Bali cattle male age 4 years, respectively. The parameter was feed consumption, performance, daily body weight gain (DWG), and feed consumption rate (FCR). The results showed that the average feed consumption, DWG, and FCR, showed significantly different (P<0.05) on feed concentrate containing cocoa pulp. The results indicated that 4 years of male Bali cattle was good growth performance compared to 2 years and 3 years by feed concentrate containing cocoa pulp.

Abstract

Yogurt quality is greatly influenced by many factors, including incubation time, incubation temperature, or addition of stabilizer. Agar is a type of hydrocolloid which can be used as a stabilizer ingredient in food product, because can function as thickening agent. Syneresis is one indicator of measuring yogurt quality. In this study, a starter Lactobacillus bulgaricus was used which was obtained from isolated cultures from commercial yogurt. During the study, the culture was routinely propagated in 10% reconstituted skimmed milk (RSM). The experiment design used was a completely randomized design, with an agar concentration as dependent factor of 0%; 0.1%; 0.2%; 0.3%; 0.4% and 0.5%. The variable measured was syneresis (%) using the drainage method. Each treatment was repeated 5 times. Based on variance analysis, indicated that agar addition with a concentration of 0 - 0.5% has a very significant effect on yoghurt syneresis. The syneresis decreased along with the increase in agar levels with the lowest syneresis value in the addition of 0.5% agar with an average value of 10%. From this study it can be concluded that the addition of 0.5% agar level reduces the syneresis (value of 10% syneresis), although this syneresis is still quite high, where in the manufacture of yogurt there should be no syneresis (0% syneresis)

Abstract

Meatballs are generally cooked using the conventional method, namely the conduction method or using a stove, this cooking has several drawbacks including the amount of energy wasted during cooking, a long time and an uneven level of maturity. Currently, many ohmic cooking technologies have been developed as a substitute for conventional cooking. This technology has advantages such as being environmentally friendly because it does not use fossil fuels and the temperature is easily controlled. This technology uses the principle of electrical resistance (ohms) to generate heat, so that the heat that arises comes directly from the product itself, not from heat that is outside, such as fire or radiation. The main requirement that must be met is that the material must have conductivity or be able to conduct electric current. Salt is one of the electrolytes that are able to conduct electric current so that ohmic technology can be applied to meatballs. This study aims to determine the effect of salt concentration on the physico-chemical characteristics of beef meatballs. Three levels of salt concentration (2%, 3%, and 4%) tested on 9 samples of meatballs. The results showed an increase in the strength of Gel (P<0.01), antioxidant activity (P<0.05) and dissolved protein content (P<0.01) with increasing salt concentration given. This study concluded that the use of ohmic technology gave good characteristics of meatballs where this cooking was able to increase gel strength, antioxidant activity and protein content.

Abstract

Partnership systems still become an interesting issue to discuss. Partnerships with beef cattle farmers can be carried out by several parties, including the private sector, universities, and local governments. Therefore, this study aimed to compare the partnership systems of regional governments and Hasanuddin university from the perspective of beef cattle farmers. This study was conducted in Barru Regency, South Sulawesi Province, Indonesia, from September to December 2018. The samples comprised farmers who participated in the partnership system in Tanete Riaja Subdistrict, Barru Regency, amounting to 80 people. Farmer perceptions of the partnerships were assessed using descriptive statistics with a distribution frequency. The results showed differences in the partnership system between tertiary institutions and local governments, namely, from the system of sharing results and the different benefits obtained by farmers if partnering between universities and local governments.
