Yelly Magdalena Mulik — 2023-02-18

Flamboyant (Delonix regia) is a plant that thrives all year round. This study aims to evaluate the nutritional content of flamboyant leaves processed with different processing methods. The study took in the Animal Feed Nutrition Laboratory of State Agricultural Polytechnic of Kupang from June to August 2022. The experimental design used was a Completely Randomized Design (CRD) with 5 treatments and 5 replications. The treatments tested were F1: flamboyant was dried in the shade for 5 days, F2: flamboyant was soaked in water for 4 hours, F3: flamboyant was soaked in a solution of rubbing ash for 4 hours, F4: flamboyant was ammoniated for 3 weeks, F5: flamboyant was fermented for 3 weeks. The results showed that the treatment tested had a very significant effect (P<0.01) on the content of organic matter, crude protein and crude fiber but had no effect (P>0.05) on the content of dry matter and crude fat. It can be concluded that the water immersion can increase the organic matter content, ammonia treatment increases the crude protein content and reduces the crude fiber content of flamboyant leaves.

Characteristics of Fried Milk Made of Cows Milk by Using of Papain as a Coagulant

Yakob Robert Noach — 2023-02-18

This research aims to determine the effect of the use of papain as a coagulant on physical and organoleptic of fried milk made of cows milk. The Completely Randomized Design (CRD) with 4 treatments and 4 replication was applied in this experiment. Those treatment were papain levels tested consist: P₁: 0.5% of milk volume, P₂: 1% of milk volume, P₃: 1.5% of milk volume and P₄: 2% of milk volume. Variables measured were curd yield, fried milk yield, density, pH, color, taste, aroma and texture. The results showed that the treatment had a significant effect (P<0.05) on curd yield, density, pH and texture of fried milk and had no significant effect (P>0.05) on fried milk yield, color, taste and aroma. It can be concluded that increasing of papain level can decreased curd yield and density, increasing of fried milk yield, pH and smoother in texture,but stabilized in color, taste and aroma of fried milk. The best results found at the use of papain as much as 0.5% (P₁)

Potential of agricultural waste (rice and corn straw to development of cattle in Harau District, Lima Puluh Kota Regency

Resolinda Harly — 2023-02-18

The development of livestock business requires the availability of feed, both in quantity and quality. Limited feed can cause disruption of production and reproduction of both poultry, small and large livestock. Small livestock and large livestock of the ruminant group can utilize agricultural waste as a source of forage feed. Utilization of waste is one way to save costs and also increase efficiency in providing feed. This study aims to determine 1. Availability of agricultural waste in the development of cattle, 2. Capacity of agricultural waste, 3. Carrying capacity of waste. This research was conducted in Harau District, Fifty City District. The research method used is a survey method with the main research data source coming from the Central Bureau of Statistics (BPS), and supporting data from related journals. Data processing using the formula for determining the potential capacity and index of holding capacity of agricultural waste. The results showed that the potential of rice and corn agricultural waste available in Harau District was 74,389,240 tons which could accommodate 22,707 ST cattle. Of the existing population, agricultural waste can still accommodate 15,560 ST of cattle. It can be concluded that the development of cattle in Harau District, Lima Puluh Kota Regency, can still be carried out due to the availability of forage waste at a safe IDD level, namely >2.

The Application of technical aspects of raising swamp buffalo in Pangean sub-district, Kuantan Singingi Regency

Yendraliza Yendraliza — 2023-02-18

Buffalo (Baballus buballis) is a large ruminant livestock that has long been known by the people of Indonesia. Pangean sub-district is a sub-district that has a fairly large population of buffalo, namely 876 heads. In general, farms in Pangean District have not implemented the technical aspects of maintenance and there are still many deficiencies that need to be addressed and repaired by breeders. This study aimed to determine the application of technical aspects of maintenance including parts of breeding, housing, feed, health and maintenance management in Pangean District, Kuantan Singingi Regency and the structure of the buffalo population. The method used in this study was a survey method with 151 farmers as respondents. The variables in the study were the profile of respondents, aspects of breeding, housing, feed, health, maintenance management, and population structure of buffaloes. The results of this study indicate that the characteristics of the respondents consisted of 79.47% male and 20.53% female, the age of the breeders ranged from 32-68 years, 35.76% graduated from high school, had livestock farming experience of 1-13 years, and the main occupation was as farmers 49.01%. Implementation of technical aspects of maintenance with the following percentages: nursery aspect 42.05%, housing aspect 58.68%, feed aspect 33.33%, health aspect 73.51%, and maintenance management aspect 62.03%. It can be concluded that overall the technical aspects of raising buffalo livestock in Pangean District, Kuantan Singingi Regency, with an unfavorable percentage of 53.92%. The population structure of buffalo in the Pangean District is dominated by female livestock.

The effect of use of egg citrate-yellow threatener with young coconut water level on quality Spermatozoa of the sheep

Hendriawan Kapoteng Bili — 2023-02-18

This study aims to determine the effect of using young coconut water as a diluent on viability, spermatozoa abnormalities and pH of ram semen. This research has been carried out for 2 months, from June to August 2021, and has been carried out in a sheep semen shelter in Naiola Village, South Bikomi District, North Central Timor Regency and evaluated at the Laboratory of the Faculty of Agriculture, Timor University. This study used a completely randomized design (CRD) with four treatments and five replications. The R1 treatment without young coconut water, R2 treatment 10% young coconut water, R3 treatment 15% young coconut water, R4 treatment 20% young coconut water. The results showed that the effect of treatment was significantly different (P<0.05) on the viability of spermatozoa. The average spermatozoa viability of each treatment was P1 of 78,0±8,15, P2 of 75,2±7,79, P3 of 71,8±9,44 and P4 of 66,8±4,54. Spermatozoa abnormalities were not significantly different (P>0.05). Spermatozoa abnormalities of treatment P1 were 8,4±1,14, P2 was 9,2±0,83, P3 was 9,4±1,34 and P4 was 9,6±3,84. The degree of acidity (pH) of semen was significantly different (P<0.05) between treatments. The pH values of each treatment were P1 of 6,79±0,16, P2 of 6,53±0,34, P3 of 6,47±0,33, and P4 of 6,35±0,20. So this study concluded that the addition of young coconut water level of (20%) can still maintain the viability, normality of spermatozoa and pH of ram semen.
