Abstract

Availability of forage fodder both in quality and quantity is an important factor in determining the success of the ruminant livestock business. The purpose of this study was to determine the effect of plant spacing and fertilizer dosage on the production of Taiwan Elephant Grass (Pennisetum purpureum cv. Taiwan) at different cuts. The field research was conducted using a Randomized Block Design (RAK) with a 3 x 4 factorial pattern, where three treatments were plant spacing (Factor A), and four treatments were dosed with fertilizer (Factor B). Each treatment combination was repeated three times so that there were 36 plots of treatment combinations. (Factor A) which consists of 3 types of spacing, namely (J1 ) 30 x 50 cm, (J2 ) 40 x 50 cm, (J3 ) 50 x 50 cm and 4 doses of fertilizer treatment (Factor B) which consists of 4 doses of fertilizer namely without fertilizer (D0), 10 tons//ha (D1), 20 tons/ha (D2), 30 tons/ha (D3). The variables measured were total plant production, botanical composition, and air dry weight (DW). Based on the study results, the spacing treatment had a significant effect (P<0.05) on the total production of Taiwan Elephant Grass stems at the first cutting. In contrast, the total plant weight, % stem, % leaf, air-dry weight (DW) had no significant effect (P> 0.05) on all observed variables. All the variables observed at the second and third cuts were not significantly different (P>0.05), but the total crop production at the third cut was higher than the second cut. The type of fertilizer had no significant effect (P>0.05) on all observed variables such as total plant weight, % stem, % leaf, total stem weight, total leaf weight.

Abstract

Cayenne pepper is one of the agricultural commodities that has high economic value and its demand continues to increase along with the development of the population. Efforts to increase the production and quality of various types of plants continue to be carried out, by utilizing various types of fertilizers. The purpose of this study was to determine the response of growth and yield of cayenne pepper using organic and inorganic fertilizers. This research was carried out at the Experimental Garden of the Local Waste Processing Site in Kusamba Village, Klungkung Regency, and the Laboratory of the Agrotechnology Study Program, Faculty of Agriculture, Warmadewa University, Denpasar from March to November 2021. The method used in this study was experimental, using a Randomized Block Design (RBD). ) with 1 factor and 4 replications. The variables observed were plant height, number of leaves, stem diameter, number of fruit, fruit weight per plant, and fruit weight per ha. The results showed that the application of various types of fertilizers can increase all observed variables. The best fertilizer for the growth and yield of cayenne pepper is NPK fertilizer.

Abstract

Pig livestock is one of the livestock developed in Indonesia because it can adapt to environmental conditions, has good production and reproduction properties including fast growth so that the body matures and quickly, the number of liters of labor size is large, birth weight and weaning weight are high, meat production is high and can also meet human needs. To meet human needs for protein and the economy, it is necessary to increase the production and productivity of pig livestock by paying attention to reproductive aspects, and nutrition. This study aims to determine the influence of the time interval of male mating in nature which affects the conception rate, liter size, and mortality. This research was carried out in Catur Village, Kintamani District, Bangli Regency from April to August 2022. This study uses a quantitative descriptive method by mating males at time intervals and observing the results directly. The number of livestock used in this study was 6 landrace sows consisting of 1 sow mated with males at intervals of once a week, 2 heads mated at intervals twice a week, and 3 heads mated at intervals of three times a week. The variables observed in this study were conception rate, liter size, and mortality. The results showed that the interval of mating time influenced the conception rate value and the number of liters of size. The best interval from the results of this study is one mating in a week, namely a conception rate of 100%, the number of liters size 9 heads. And the time interval of mating has no effect on the mortality of the child at birth.

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.

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. Keywords: Coffee Skin, Fermentation, Pig, Reproduction
