THE ROLE OF EXTENSION TO THE ADOPTION OF FARMERS INNOVATION IN THE DEVELOPMENT OF WEST TOMOHON DISTRICT TOMOHON CITY. Study was conducted on December 2019 to evaluate the role extension in the adoption of smallholder innovation in development of native chicken at West Tomohon District. This research was a survey using questionnaires. Samples were determind by purposive sampling method involving 30 smallholder of local native chicken. Chi square method was used to analyze the data. The role of extension was meansured by ordinal scale for questions given to breeders and the adoption of innovationÂ was measured by ordinal scale of the levelÂ Â of knowledge, attitudes and skills of native chicken farmers. Knowledge was divided into several categories, namely high, medium and low knowledge, the attitude of the category accepts innovation, it is enough to accept innovation and reject innovation, the skill of the category was skilled, sufficiently skilled and unskilled. The results of the study used Chi-Square analysis showed that the role of extension workers had a significant relationship with the attitudes of native chicken farmers while on the other hand the role of extension workers did not not have a significant relationship with the knowledge and skills of native chicken farmers.

THE EFFECT OF WHITE TURMERIC (Curcuma mangga Val.) ADDITION ON CHICKEN MEAT AGAINST WATER CONTENT, pH AND MICROORGANISM NUMBERS. The purpose of this research was to determine the effect of the addition of white turmeric (Curcuma manggaVal.) on chicken meat at cold storage (4oC). This research used Split Plot Design with 2 treatment factors based on completely randomized design. The Main Plot contains of 4 treatments (A0 = without storage, A1 = 3 days storage, A2 = 6 days storage, A3 = 9 days storage) and the Sub Plot contains of 4 treatments (B0 = without white turmeric, B1 = 4% grating of white turmeric, B2 = 8% grating of white turmeric, B3 = 12% grating of white turmeric). The variable that observed are water content, pH and microorganism number. The result showed that the addition of white turmeric was not significant affected (P > 0.05) against water contentof chicken meat, however it was highly significant affected (P < 0.01) against pH and microorganism numbers of chicken meat. Storage time was highly significant affected (P <0.01) against water content, pH and microorganism numbers of chicken meat. The interaction between both of treatment factors was given highly significant affected (P < 0.01) against water content, pH and microorganism numbers of chicken meat. As a conclusion, the addition of white turmeric on chicken meat was not affected against water content, however it can decrease pH and obstruct microorganism activity. Keywords : chicken meat, white turmeric, pH, water content, microorganism numbers

THE EFFECT OF YELLOW PUMPKIN (Cucurbita moschata) MEALIN THE DIET ON THE CARCASS, CARCASS COMMERCIAL CUTTING AND ABDOMINAL FAT OF BROILER CHICKENS. This study aims to determine the effect of pumpkin (Cucurbita moschata) waste in the diet on carcass percentage, commercial cutting of carcass (breasts, thighs, wings) and abdominal fat in broilers. The study used 100 unsexed D.O.C. of broilers, strain Cobb. The experiment used a completely randomized design (CRD) consisting of 4 treatments and 5 replications. The follow-up test used was Honest Real Difference (BNJ). The treatment arrangements are as follows: R0 = Basal Diet (BD) 100% + 0% Yellow Pumpkin Meal (YPM); R1 = BD 95% + 5% YPM; R2 = BD 90% + 10% YPM; R3 = BD 85% + 15% YPM. The results showed that carcass weight and carcass percentage in treatment R0, R1, R2 were significantly higher than treatment R3, but between treatments R0, R1, R2 were not significantly different. The commercial section of the right chest of treatment R1, R2, R3, was significantly higher than the R0 treatment, but between treatments R1, R2, R3 were not significantly different, while on the left chest showed that treatments R0, R2, R3 were significantly higher than R1, however, between treatments R0, R2, R3 were not significantly different. Thigh and wing sections, and abdominal fat percentage showed no significant differences. Based on the results, it can be concluded that15% pumpkin waste mealin broiler diet has a good effect on body weight growth, carcass percentage and part of the commercial cutting percentage of broiler carcass.

ABSTRACT VEGETATIVE GROWTH OF BROWN MIDRIB (BMR) SORGHUM ON THE DIFFERENT LEVELS SHADE OG SHADE AND POPULATIONS DENSITY. The present study was conducted to determine the effect of shading area and plant population density and their interaction on vegetative growth of Brown Midrib (BMR) Sorghum. A Completely Randomized Design (CRD) in a Factorial arrangement with 2 factors of nitrogen level and shading area, as follows: factor A = shading area of A1 = no shading area (0%), and N2 = shading area; whereas factor B = plant population density of B1 = 4 plants, B2 = 6 plants, B3 = 8 plants, and B4 = 10 plants. Variables measured were: leaves number, plant height, and the correlation between leaves number and plant population density. Research results showed that plant height in open area (no shading) was about 86.33 cm and significantly higher (P < 0.05) compared to other treatments. Leaves number in open area was about 7.55 sheats and significantly higher (P < 0.05) compared to other treatments. It can be concluded that shading positively decreased or retarded Brown Midrib (BMR) Sorghum growth as indicated by lower plant heights in shading area. In a limited daylight, plants needs an adaptation period to fulfill their needs for photosyntesis processes. Â Key words: brown midrib (BMR) sorghum, growth, population density, shading

WATER HOLDING CAPACITY AND COOKING LOSS OF DRIED AND VACUUM PACKAGE BEEF MEAT. Fresh meat is categorized into perishable physical and chemical material product due to high nutrient composition as the main media of growing microorganism. This meat damage could be handled by drying and vacuum package method. The objective of this study was to evaluate effect of drying time period and storage time period on water holding capacity and cooking loss of vacuum package beef meat. Treatment was conducted using completely randomized design divided into two factors with three replications in each combination of the factors. Factor A, as main plot of drying time period was divided into 12 hours (A1), 16 hours (A2) and 20 hours (A3). Factor B as sub plot of storage time period in room temperature of 270 C was divided into 00 C (B0), 120 C (B1), 240 C (B2), and 360 C (B3). Results showed that treatments affected significantly quality of beef meat. There was no interaction effect on water holding capacity and cooking loss of vacuum package beef meat. Beef meat being dried during 16 hours with temperature of 60 0C using vacuum package and stored at room temperature of 270 C during 36 days produced normal standard of water holding capacity and cooking loss of meat. Â Key words: water-holding capacity, cooking loss, vacuum package.
