Abstract

This study aims to determine the dosage of Swallow fertilizer and the dose of NPK fertilizer on the growth and yield of cucumber plants. This study used a randomized block design (RBD) in a factorial pattern with 2 treatment factors, namely: The first factor was swallow fertilizer consisting of 4 treatment levels, namely: without fertilizer, 10 tons ha-1, 20 tons ha-1, 30 tons ha-1, The second factor is NPK fertilizer consisting of 4 treatment levels, namely: without fertilizer, 150 kg ha-1, 300 kg ha-1, and 450 kg ha-1. Treatment of swiftlet fertilizer doses showed a significant to a very significant effect on all variables observed except for fruit dry weight per plant which had no significant effect. The highest yield of fresh fruit weight reached 732.67 g obtained in the swiftlet fertilizer treatment of 30 tons ha-1. NPK fertilizer dose treatment showed a very significant effect on all observed variables except for the variable cucumber flower exit time, cucumber fruit exit time, fruit dry weight per plant, and dry fruit weight per plant had no significant effect. The yield of fresh fruit weight reached 665.57 g obtained in the NPK fertilizer treatment of 150 kg ha-1. The interaction between swiftlet fertilizer dose and NPK fertilizer dose showed results that had a significant to a very significant effect on all variables observed except for the non-significant effect obtained on the cucumber fruit discharge time and fresh fruit weight per plant. Recommendations for swiftlet fertilizer 30 tons ha-1 and NPK fertilizer 150 kg ha-1 can be used to increase cucumber yields. Keyword: Organic fertilizer, swallow droppings, NPK fertilizer, cucumber.

Abstract

This study aims to determine the effect of using fermented coffee husks as substitute feed and at what level it affects the growth of super-free-range chickens. The research method was carried out using a completely randomized design factorial pattern consisting of 2 factors. The first factor consisted of 3 treatments of fermented coffee skin substitution, namely: K0 = 100% commercial feed, K1 = 95% commercial feed + 5% substitute for fermented coffee skin, K2 = 90% commercial feed + 10% substitute for fermented coffee skin. The second factor consisted of 2 treatments of giving drinking water, namely: A0 = without giving alkaline water, A1 = giving alkaline water with a concentration of 20% in drinking water. The results showed that the substitution of fermented coffee skin on commercial feed had a significant effect on body weight gain in the fifth week. Meanwhile, weight gain at weeks 1, 2, 3, 4, 6, and final weight had no significant effect. Carcass weight and carcass composition had no significant effect but the K1 treatment always gave the highest average. The treatment with alkaline water had no significant effect, the average weight gain was always higher in treatment A1. Based on the results of the study, it can be concluded that the substitution of fermented coffee husks in commercial feed for free-range chicken had a significant effect on body weight gain in the fifth week, but on other variables such as final weight and composition of carcass parts had no significant effect. Meanwhile, the addition of alkaline water and without alkaline water had no significant effect, but the addition of alkaline water had a higher average value for both growth and carcass parts. Substitution of fermented coffee skin on commercial feed as much as 5% showed better results than without substitution and 10% substitution. Keywords: Fermented Coffee Skin, Alkaline Water, super local chicken

Abstract

Specialty Arabica coffee is coffee beans, roasted coffee, and ground coffee that come from a certain geographical area and have a delicious, unique, and different taste from other coffees. So far, Bali Kintamani Arabica Coffee, which is classified as specialty coffee, grows and develops at altitudes above 1,000 meters above sea level. The study aimed to determine the effectiveness of the application of GAP in increasing the productivity of Kintamani specialty Arabica coffee, to find out what factors influence the strategy for increasing the productivity of Kintamani speciasylty Arabica coffee, and to find out what strategies can be applied to increase the productivity of Kintamani specialty Arabica coffee. This research was conducted in Belantih Village and Catur Village, Kintamani District, Bangli Regency, Bali Province. To analyze the effectiveness of implementing Good Agricultural Practices, researchers used descriptive qualitative analysis to analyze the data obtained from the results of the FGD (Forum Group Discussion) conducted at the research location. The application of GAP turned out to affect increasing the productivity of Kintamani specialty arabica coffee. The results of IFE and EFE analysis on the IE Matrix found that Kintamani specialty Arabica coffee was in a strong position and had opportunities, so 7 strategies were developed, namely collaboration in raw material research, raw material supply chain, and alternative raw materials. procurement, development of product diversification that has Kintamani identity or characteristics through strategic research results, conducting periodic performance appraisals, preparing alternative supply chain strategies for raw materials to distribution, designing farmer group cooperation to secure market prices, developing production operational standards through adjustments and approaches to local culture, developing integrated promotion management. Keywords: Good Agricultural Practices, Strategy, Productivity, Arabica Coffee Specialty, Kintamani

Abstract

The development of pig livestock is supported by feed that has a high nutritional content, namely fermented coffee skin which can increase livestock reproduction to increase livestock production and productivity. The aim of the study was to evaluate the substitution of fermented coffee skins on the reproduction of landrace sows and at what level the substitution of fermented coffee skins affected the reproduction of landrace pig. This research method used a completely randomized design (CRD) with four treatments T0 = 100% Commercial Feed, T1 = Commercial Feed (95%) + 5% Fermented Coffee skin, T2 = Commercial Feed (90%) + 10% Fermented Coffee skin, T3 = Commercial feed (85%) + 15% fermented coffee skin. Each treatment was repeated 3 times so that there were 12 experimental livestock units. The results showed that substitution of fermented coffee skin had no significant effect on estrus, namely 2.67-3.00 days, estrus cycle 19.67-20.67 days, birth weight 1.32-1.65 kg, and mortality 0.33-1.67%, but 5% fermented coffee skin substitution had a significant effect on gestational age, namely 113.67 days, litter size of 11 tails, weaning weight of 8.05 kg. It can be concluded that 5% fermented coffee skin substitution gave the best results on estrous variables, estrus cycle, litter size, birth weight, weaning weight and mortality.

Abstract

This study aims to determine the effect of the type of biochar and various doses of poschar and their interactions on the growth and yield of red chili plants. The design used in this study was a factorial randomized block design consisting of 2 treatment factors, namely factor one: type of biochar (B) which consisted of 3 levels, namely: without biochar treatment and with cow biochar and chicken biochar. Second factor: Poschar dose consists of 2 levels, namely: Poschar 0 tons/ha and goat poschar 15 tons/ha. Thus there were 6 treatments and repeated 3 times, so 18 experimental plots were obtained. The interaction between biochar type treatment and poschar dose did not significantly affect all observed variables except stem diameter and the number of productive branches. Biochar treatment significantly affected maximum plant height, stem diameter per plant, number of fruits per plant, and fruit weight per plant, but did not significantly differ on maximum number of leaves, number of productive branches per plant, fruit length per plant, fruit diameter per plant. Poschar treatment had a significant effect on maximum plant height, maximum number of leaves, number of fruits, and fruit weight per plant, but did not significantly affect stem diameter, number of productive branches, fruit length, and fruit diameter per plant. The highest weight of chili fruit was obtained from biochar cow which was 1465.81 g which was significantly different or increased by 63.72% compared to without biochar, which was 895.32 g. The highest fruit weight per plant was obtained in goat poschar application at a dose of 15 tons/ha which was 1440.87 g, significantly different or increased by 42.96% from without poschar which was 1007.90 g. Keywords: Biochar, Compost, Poschar, livestock waste, chili plants.
