Abstract

Abstract The livestock sector plays a real role in national food security through the supply of animal protein, one of which is super village chickens. In increasing the productivity of livestock the most important is rations. Feed materials that need to be used as alternative feed materials include agricultural waste, one of which is sweet potato brangkasan (Ipomoea batatas). The purpose of this study was to find out the effect of giving sweet potato brangkasan flour to the variable physical composition of chicken villages until the age of 10 weeks. The experimental design used is a Complete RandomIzed Design (RAL) consisting of 5 treatments, namely: R0 (Ration without sweet potato brangkasan flour as a control), R1 (Ration contains 3% sweet potato brangkasan flour without fermentation), R2 (Rations contains 3% fermented sweet potato brangkasan flour), R3 (Ransum contains 6% fermented sweet potato brangkasan flour), R4 (Ration contains 9% fermented sweet potato brangkasan flour). Each treatment is repeated three times. The results showed that the addition of fermented and non-fermented sweet potato brangkasan flour did not have a noticeable effect (P>0.05) on the physical composition of the thigh carcass and the physical composition of the meat as well as on the skin and subcutaneous fat of the chicken breast super village, but a real effect (P<0.05) on the physical composition of the breastbone. The provision of 3% fermented sweet potato flour (R2) tends to be able to give the results of the physical composition of the chest and thigh carcass higher.

Abstract

Green beans have advantages over other food crops in terms of agronomy and economy, such as: (1) shorter-lived between (55-65 days) can be harvested, (2) more drought-resistant with relatively small water requirements for green bean growth, namely 700-900 mm / year. In rainfalls that are lower than that, it can still grow because it is deeply rooted, (3) it can be planted on less fertile land and fertilize the soil because it is symbiose with rhizobium and produces as much biomass (11-12 t/h), (4) easy cultivation methods are sufficiently minimal tillage and seeds are sown, (5) pest attacks are less diseased and (6) the selling price is high and stable. The purpose of the study was to determine the effect of planting distance and application of rabbit manure on the growth and yield of green bean plants (Vigna radiata L). The experimental design used was with a randomized design of the group and the analysis of the F test (analysis of variance) on the. This research was carried out in Subak Rapuan, Mas Village, Ubud District, Gianyar Regency with an altitude of 400 meters above sea level. The implementation of the study starts from March - June 2022. The highest fresh weight of seeds at the spacing treatment (J3) can be caused by wide planting distances and optimal fertilizer application. The wider planting distance provides space for access to sunlight, air temperature, and air humidity that can contribute to the growth and development of plants. The wider planting distance will reduce the competition higher so that with the J3 planting distance, it reduces the occurrence of nutrient competition so that the nutrients given through K3 fertilization will be used properly by plants. This shows that a dose of rabbit manure of 15 tons/ha-1 has the best effect on the growth of green beans so that it gives high yields compared to doses of 5 tons/ha-1 and 10 tons/ha-1. The fresh weight of seeds per plant is strongly supported by the presence of correlations in the number of pods (r = 0.889**) the length of the pods (r = 0.828*) and the number of seeds (r = 0.921**).

Abstract

Chrysanthemum (chrysanthemum morifolium R.), is an ornamental plant that has economic value and has the potential to be developed in national and international trade. This study aims to determine the effect of the type of cow manure and NPK fertilizer dosage on growth and yield of chrysanthemum plants. The hypothesis put forward in this study was that cow manure (20 tons ha-1) and NPK fertilizer doses (1000 kg/ha) could increase growth and yield of chrysanthemum plants. The experimental design used in this study was a factorial randomized block design with 2 treatments, namely the type of organic cow manure (S) consisting of 4 levels, namely: S0 = without cow manure, S1 = 10 ton/ha-1 cow manure, S2 = 20 tons/ha-1 cow manure, S3 = 30 tons/ha-1 cow manure, and the dosage of NPK fertilizer consists of 4 levels, namely: D0= without NPK fertilizer, D1= 1000 kg/ha, D2= 2000 kg/ha, D3 = 3000 kg/ha. Research data were analyzed statistically using analysis of variance. For a single treatment that had a significant to very significant effect, it was continued with the LSD test at the 5% level. The results of statistical analysis showed that the interaction between the type of cow manure and the dose of NPK fertilizer (S x D) had no significant effect on (P≥0.05) on all observed variables. The highest economic fresh weight of flowers was obtained at the type of manure 20 tons/ha, namely 26.53 g, compared to no organic fertilizer, namely 23.55 g. The highest economic fresh weight of flowers was at a dose of NPK 1000 kg/ha (D1), namely: 26.26 g, compared to NPK 2000 kg/ha is 24.98 g.

Abstract

Tempeh is a processed vegetable product made from legumes. Tempeh has a softer texture than soybeans, because the tempeh mold digests the matrix between the cells of soybean seeds, so that the cells are separated from the surrounding materials. Efforts to improve the quality of tempeh by adding Moringa (Moringa Oliefera) leaf extract were carried out in this study. The purpose of this study was to determine the effect of the addition of Moringa leaf extract on tempeh and determine the vitamin C content and organoleptic on tempeh. This method that I used was an experimental method with a complete randomized design (CRD) with 6 treatments and each repeated four times. The treatments were the addition of moringa leaf extract at 0%, 1%, 2%, 3%, 4%, and 5%. The analysis was conducted on vitamin C content and organoleptic test. The results of this study showed that the addition of moringa leaf extract had a significant effect on the protein, fat, and carbohydrate content of tempeh. The addition of moringa leaf extract as much as 5% increased the protein content by 1.47% fat by 1.41% and carbohydrates by 0.70%, tempeh with the addition of moringa leaf extract 4% and had the best value in all aspects of the organoleptic test, namely aroma, taste, texture and color. The conclusion of this study is the addition of moringa leaf extract affects the vitamin C content and organoleptics in tempeh.

Abstract

Sate aci made from tapioca flour can be given culinary variations by adding dried rebon shrimp which can enrich the flavour and nutrients contained in it. Especially the protein content in dried rebon shrimp can increase the nutritional quality of aci satay. This study aims to see the effect of the addition of dried rebon shrimp on the increase in protein and organoleptic tests on aci satay with 4 parameters namely colour, aroma, texture and taste. The making of dried rebon shrimp aci satay with 6 treatments of dried rebon shrimp addition (0 g, 10 g, 20, g, 30 g, 40 g and 50 g) will be tested by kjeldahl method to determine the protein content and taste test to 30 panellists. This research design applies a completely randomised design with 4 replications. Sate aci without the addition of dried rebon shrimp will be used as a control. The results of this study showed an increase in protein content in dried rebon shrimp aci satay with the highest value of 7.26% in the treatment of adding dried rebon shrimp 50 grams. Organoleptic test results from the most preferred and accepted panellists were in the treatment of adding 10 grams of dried rebon shrimp.
