Abstract

The purpose of this study was to determine the effect of doses of potassium nitrate and magnesium sulfate on the production of Siamese orange (Citrus Nobilis Var. Microcarpa L.) and their interactions, which was carried out in Bayung Gede Village, Kintamani District, Bangli Regency from December 2021 to July 2022. This study used a Randomized Block Design (RAK) with 2 factors arranged in a factorial manner. The first factor that was tried was the dose of potassium nitrate (K) fertilizer which consisted of 4 levels, namely: K0 (0 g/tree), K1 (250 g/tree), K2 (500 g/tree) and K3 (750 g/tree). . . While the second factor was the dose of magnesium sulfate (M) fertilizer which consisted of 4 levels, namely: M0 (0 g/tree), M1 (5 g/tree), M2 (10 g/tree) and M3 (15 g/tree). Thus, there were 16 treatment combinations, each given 3 times, so 48 citrus trees were needed. The results showed that the interaction of potassium nitrate fertilizer dose with magnesium sulfate (KxM) fertilizer did not significantly affect all observed variables. The highest fruit weight per tree was obtained at a dose of potassium nitrate fertilizer of 750 g/tree, which was 11.53 kg, an increase of 96.75% when compared to without potassium nitrate fertilizer which was only 5.86 kg. While the magnesium sulfate fertilizer treatment obtained the highest harvested fruit weight per tree at a dose of 15 g/tree, namely 10.17 kg, an increase of 30.05% when compared to magnesium sulfate fertilizer which was only 7.82 kg.

Abstract

Super free-range chicken is currently a very promising new business opportunity due to very high consumer demand. To support the demand for super free-range chicken meat, it is necessary to develop super free-range chicken farms in order to meet the increasing demand from year to year. The purpose of this study was to determine the effect of giving rations containing taro tuber flour on the carcass percentage of super free range chickens aged 10 weeks. This study used a completely randomized design (CRD) with 5 treatments and 3 replications. Each replication consisted of 5 chickens so that the number of chickens used was 75. The treatments were R0 control rations without taro tuber flour, R1 rations containing 5% taro tuber, R2 rations containing 10% taro tuber, R3 rations containing 15% taro tuber and R4 rations containing 20% ​​taro tuber. The results showed that the ingredients of taro tuber flour in the ration had a significant effect (P<0.05) on the slaughter weight and carcass weight of super free-range chicken, but did not have a significant effect (P>0.05) on the percentage of carcass and non-carcass percentage. . Giving 10% taro tuber flour (R2) produced the highest slaughter weight and carcass weight. The keywords are: Super Kampung Chicken and Taro Tuber Flou

Abstract

Sugarcane (Saccharum Officinarum L.) is the basic ingredient for making sugar. In Indonesia, in the last 5 years, sugar productivity only reached 5.2 tons/ha, very different from the productivity in 1935-1940, which averaged 17 tons/ha. This is because this Aat variety has not yet reached the desired productivity rate. The purpose of this study was to determine the diversity of growth of sugarcane (Saccharum officinarum L.) in clone SB01, clone SB03, clone SB04, clone SB11, clone SB12, clone SB19, clone SB20, variety PS862 and variety Bululawang. This research was carried out in the Djengkol garden, Ploso Klaten, Kediri. The tools used are sickle, cloth, tape measure, caliper, camera and stationery. The materials used are clone SB01, clone SB03, SB11, SB12, SB19, SB20, PS862 variety, Bululawang variety. Observations included growth variables (stem height, number of stems, number of leaves, stem diameter). Data analysis used ANOVA with a 5% F test. If there is a significant difference, proceed with the 5% DMRT test, correlation test, genetic diversity, heritability, genetic progress. Clone SB12 had an advantage in variable stem height of 395.83 (cm), number of stems 5.67 (stem), number of leaves 9.44 (strands), while clone SB01 had an advantage in stem diameter with the highest value of 31.99 (mm). Correlation relationship on sugarcane plant growth variables. The diversity of 7 clones and 2 varieties is heavily influenced by genetics and slightly influenced by the environment as shown by the KKG values in the medium-high category, the KF values in the low-high category, the Heritability (H2) medium-high category and the genetic progress (KG) category. rather high.

Abstract

The purpose of this study was to determine the effect of giving fermented rice bran in the ration on the performance of male quail aged 2-7 weeks and to determine the level of fermented rice bran could produce the average initial body weight, body weight gain, final body weight, feed consumption and FCR ratio. The study was conducted using a completely randomized design (CRD) with 5 treatments and 3 replications. Each replication consisted of 3 male quails so that the number of male quails used was 45. As for the treatment as follows, the ration without the content of fermented rice bran as a control and the ration of fermented rice bran 5%, 10%, 15% and 20%. Parameters observed were initial body weight, weight gain, final body weight, feed consumption, and FCR (Feed Conversion Ratio). The data obtained were analyzed for variance. From the results of this study, the provision of fermented rice bran in commercial rations of male quail feed in the grower-finisher phase showed significantly different results (P<0.05) on final body weight, body weight gain, feed consumption, and FCR. Based on the results of this study, it is recommended that male quail breeders use fermented rice bran at a level of 20% in the ration because this level shows good results compared to the performance of male quail at a treatment level of 0% without fermented rice bran.

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. Keywords: Super Kampung Chicken, Carcass Physical Composition, Sweet Potato Flour

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**).
