Abstract

Abstract: The fermentation of corn straw fiber and sorghum straw by using Phanerochaete chrysosporium fungus is done to improve its nutrition quality. This research was done in a laboratory by using a Complete Random Plan with factorial pattern of 2 x 4 and was repeated 3 times. The first factor was the type of straw, they were corn and sorghum straws. The second factor was the dosage of fungus inoculumss of Phanerochaete chrysosporium, each in 0% v/w (Pc0), 2% v/w (Pc1), 4% v/w (Pc2) and 6% v/w (Pc3). When there was a real difference, it was then continued Different Real Honest Test. The use of fungus inoculums of Phanerochaete chrysosporium in real has improved the content of ADF (2,92%), cellulose (3,59%), and has really decreased the content of NDF (1,85%), hemicellulose (7,48%), and the content of lignin (7,26%).  There was no interaction between the type of straw with the dosage of fungus inoculums of Phanerochaete chrysosporium towards the changes in the content of NDF, ADF, hemicellulose, cellulose, and lignin.  Corn straw has real high content of ADF, cellulose, and really decrease the content of NDF, lignin, and hemicellulose. Based on the effect of fermentation of Phanerochaete chrysosporium fungus, 6% v/w (Pc3) dosage was better as the inoculums of corn straw and sorghum straw, which was able to improve the quality of straw as food so that it has enough nutrition as an alternative food. Key words: Straw, Phanerocaete chrysosporium, Fiber.

Abstract: This research has been carried out in the stable, the research department of Animal Husbandry Faculty of Agriculture, University of Tadulako from December to April 2011. research purposes to study the stud and cement deposition appropriate intervals, in the period of fertility and produce fertile sperm and egg hatchability of high post-IB, in the hens reproductive tract, through the observation of a number of eggs produced by a certain time.The study design used was Completely Randomized Design (CRD) 3 x 3 factorial pattern, with a combination of two treatment factors (A, B). The treatments tested consisted of three (3) the stud (free-range chicken, chicken arabic, and chicken bangkok) and 3 (three) intervals of semen deposition (day 3, day 5 and day 7) on fertility of spermatozoa and the fertile period spermatozoa and egg hatchability. Each treatment was repeated as many as 3 (three) times.  The results showed that treatment of the males give real effect (P <0.05) on fertility, sperm fertile period and hatchability of eggs. The treatment interval of deposition of cement did not provide significant effect (P <0.05) on fertility and sperm fertile period, but the effect of cement deposisi interval significantly(P <0.05) on the hatchability of eggs, the two factor interactions do not occur. Key words: Effect of males, Interval of Semen Deposition dan Artificial   Inseminatioan.

Abstract

Food diversification efforts by leveraging local food, such as purple sweet potato (Ipomoea batatas Blackie) needs to be improved because of the potential to be used as a functional food ingredient. Purple Sweet Potato Starch Modification function to change the functional properties contained in starch to increase the added value as functional food ingredients. This study uses a modification Heat Moisture Treatment (HMT) on purple sweet potato starch with the treatment temperature and heating times. The study design used completely randomized design (CRD) arranged as factorial with two factors, namely by heating starch at high temperatures (70oC, 85oC and 100°C) and prolonged heating (3 hours, 5 hours and 7 hours). Data were analyzed using analysis of variance (ANOVA) followed by a further test HSD (α = 0.05). The results showed that the treatment temperature and longer heating HMT give real effect to the Oil Holding Capacity, moisture content, FT-IR, starch content, fiber content and antioxidant activity, but to the Water Holding Capacity and digestibility no significant effect. Judging from the functional value best treatment is prolonged heating temperature of 85ºC with 3 hours resulted in digestibility of 8.50%, temperature 70°C with a 3 hour long heating produces antioxidant activity of 18.79%, and prolonged heating temperature of 100ºC with 5 hours produce high levels of fiber 1,39%.

Abstract

This research aims to find out characteristics and management of goat farming on small scale farming of Tolitoli Regency. It is also to find out factors influencing the goat productivity and development and to evaluate the goat population development and its reproduction performance. This is a qualitative research. The data was collected through survey and interview. The research was carried out within 2 months from February to March 2015. The area covers 3 districts, namely: (1) North Tolitoli, (2) North Dampal and (3) Dondo. The sample size was determined based on purposive sampling. Meanwhile, the data collection method was observation, interview and documentation. The data was identified and analyzed qualitatively by using percentage frequency table, then, they were interpreted descriptively. The research result from 3 districts reveals that goat productivity had not been done maximally, goats breeders are in productive age, their education qualification is on low level. However, they have experienced in breeding goats. Nevertheless, the business is part-time job. Whereas, the birth rate is as follow: 56 percent in North Tolitoli; 65.98 percent in North Dampal and  56 percent in Dondo.  Meanwhile, their mortality is as follow: 32.86 percent in North Tolitoli; 25.56 percent in North Dampal; and 37.50 percent in Dondo. The mortality rate of adult goats is as follow: 5.71 percent in North Tolitoli; 12.50 percent in North Dampal; and 5.36 percent in Dondo. It could be concluded that the goat farmers require training and advice from the relevant authoritiees to enhance their goat productivity and to improve their family income.

Abstract

The aim of the research was to synchronize the planning of community empowerment block using at PFMU of Sintuwu Maroso Model with factual condition in field and to analyze community responses on the planning of community empowerment block at PFMU of Sintuwu Maroso Model management. Community population were those who settle around the community empowerment block. Community forest at Kilo and Buyumpondoli villages were also sampled.  The respondent number was 50 people who lived around the area of HKm and village forest.  Data were analyzed using comparison analysis, land cover analysis, and the likert scale of 1, 3, and 5.  The research results showed that the community forests at both Kilo and Buyumpondoli villages are suitable for Hkm and village forest. The land of Kilo village Hkm and Buyumpondoli village forest were dominantly covered by dry land such as plantation and bushes.  Based on the likert scale, the criteria for the community empowerment block were that RKTN/RKTP and RKTK should be directed toward forest management at small scale 198 (79%); forest with low product 228 (91%); non forest area 236 (94%); HKm, village forest, and HTR  permit 142 (56%), area close to community 250 (100%); possibility of RKTN/RKTP/RKTK to be included in either rehabilitation region or  big/small scale forest region 144 (57%); and the community responses 220 (88%).  It can be concluded that the criteria and the community responses are classified high.
