Abstract

The problem for farmers in Suruh Village is having two types of farming which are cacao-goat integrated system farmer and cacao-goat non-integrated system farmer. Cacao-goat integrated system conducts cacao farming with goat livestock while for the cacao-goat non-integrated system does not conduct goat livestock. Farmer's interest is different in conducting cacao farming system. The aim of cacao-goat integration system is obtaining manure as organic fertilizer by the expectation to save fertilization cost so that farmer's income with the cacao-goat integrated farming system will be different with non-integrated one because seen from the maintenance cost because of manure. In this study, we dig pattern analysis information of the cacao-goat integrated farming system to find out cacao-goat integrated system and income difference of cacao-goat integrated and non-integrated systems so that it aims to find out the pattern difference of cacao-goat integration farming The research result shows that cacao-goat integrated system by the utilization of cacao waste (bark, leaf), intercropped plant (avocado, cassava, stink beans) as the animal feed of goat). Goat livestock produces feces that can be used as cacao compost fertilizer after 12 months of fermentation. The average income of the cocoa-goat non-integration farmer is USD 1,184.91/Ha/Year, while for the cocoa-goat non-integration farmer has the average income of USD 854,673/Ha/Year. There is a significant difference between cacao-goat integrated farming income and cacao-goat non-integrated farming income.

Abstract

This study aims to determine the effect of 1% lysine, 0.5% methionine and the combination of lysine and methionine (1% + 0.5%) in the ration on the weight gain of carcass parts of native chickens. The design used in this study was a completely randomized design (CRD) consisting of 4 treatments and 3 replications, while the treatments were R0 (control) native chickens that were not given additional lysine and methionine, R1 native chickens were given feed containing lysine 1 %, R2 of free-range chickens given feed containing 0.5% methionine, R3 of native chickens given feed containing lysine and methionine (1% + 0.5%). The parameters observed were the weight gain in the chest, thighs, wings, and back. The data obtained were analyzed by analysis of variance. The results showed that the provision of rations which were added with the combination of amino acids lysine and methionine had a very significant effect (P> 0.01) on the weight gain of the carcass, thighs and backs of native chickens aged 10 weeks. Based on the results of this study it can be concluded that the combination of the amino acids lysine and methionine in the ration gave the best effect on the weight gain of carcass parts of native chicken aged 10 weeks. Based on the results of the study, it is suggested to add the combination of lysine (1%) and methionine (0.5%) in the native chicken ration.

Abstract

This study aims to determine the effect of the type of rabbit compost and the dose of NPK fertilizer on the growth and yield of zucchini plants. The design used in this study was a factorial randomized block design (RBD) consisting of 2 factors, namely: The first factor is rabbit compost (K) which consists of 4 levels of treatment, namely: K0 = 0 tonnes / ha, K1 = 10 tonnes / ha, K2 = 20 tonnes / ha, K3 = 30 tonnes / ha. The second factor, NPK pearl fertilizer dosage (D) consists of 4 levels, namely: D0 = 0 kg / ha-1, D1 = 100 kg / ha-1, D2 = 200 kg / ha-1, D3 = 300 kg / ha -1. Thus, there were 16 combination treatments, each of which was repeated 3 times so that there were 48 experimental plots. The research data were analyzed statistically using analysis of variance. For a single treatment that has a real to very real effect, it is followed by the BNT test at 5% level, the results showed that the interaction between rabbit compost dose and NPK (KxD) had no significant effect (P≥0.05) on all variables. The highest fresh fruit weight was obtained at the rabbit compost dose of 30 tons / ha (K3), namely 2463.64 grams, an increase of 16.09% when compared to the treatment without compost dose of 0 tons / ha (K0), namely 2084.30 grams . The high fresh weight was supported by the number of harvests per plant (r = 0.821 *), fruit length (r = 0.935 **) and fruit diameter (r = -0.975 **). The highest fruit fresh weight was obtained at the NPK fertilizer dose of 300 kg / ha (D3), namely 2488.95 grams. The fresh weight of the fruit increased by 18.23% when compared to the NPK fertilizer dose of 0 ton / ha (D0), which was 2104.87 grams. The high fresh weight of fruit was supported by the number of harvests per plant (r = 0.923 **)
