Shearing enlarges and accelerates heat dissipation from the sheep's body, giving antioxidants that help reduce the negative effects of
excessive free radical production. Ascorbic acid is an antioxidant but is easily decomposed when it enters the digestive system of
ruminants. Ascorbyl palmitate (AP) is ascorbic acid in the form of an ester which is insoluble in water. The aim of this study was to
analyze the effect of shearing and administration of AP antioxidants on oxidative stress conditions in Padjadjaran sheep subjected to heat
shock. The shaving treatment consisted of not shaving (s0) and shearing (s1),and the treatment of giving the antioxidant ascorbyl
palmitate consisted of not being given (a0) and being given (a1). Sheep were subjected to shearing, their hair was trimmed until ± 10 mm
in length was left, and sheep as object of study were treated with ascorbyl palmitate at a dose of 400 mg head-1 day-1. The combination
treatment was not shaved – not given the antioxidant ascorbyl palmitate (s0a0), only shaved (s1a0), only given the antioxidant ascorbyl
palmitate (s0a1), and sheared – given the antioxidant ascorbyl palmitate (s1a1). Heat shock is given by exposing the sheep to the sun.
The oxidative stress observed and analyzed was the profile of endogenous antioxidants consisting of superoxide dismutase (SOD), catalase
(CAT), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA). The results showed that the combination of shearing and Ascorbyl
Palmitate had a significant effect (p<0.05) on the levels of SOD, CAT and GSH-Px in Padjadjaran sheep receiving heat stress. The
conclusion from this study, the shearing treatment and the administration of Ascorbyl palmitate, both independently and in combination,
had a beneficial effect on Padjadjaran sheep.

The cultivation of this plant is constrained by the attack of plant pest organisms like Spodoptera exigua. S. exigua causes damage by causing scallions to become hollow and see-through. Alternative control of S. exigua attack is by using clove essential oil. The study was conducted in West Bandung, West Java from June to August 2021. This study used a Randomized Block Design with 5 treatments and 5 replications, namely: Control (without essential oil), clove essential oil concentration of 2.5%, clove essential oil concentration of 5%, clove essential oil concentration of 7%, and clove essential oil of 9% concentration. The results showed that clove essential oil (Syzygium aromaticum) with a concentration of 9% was the most influential treatment for the highest mortality and the lowest intensity of pest attack.

One effort to overcome these problems is by utilizing the waste of coffee skin to compost. Therefore, the provision of coffee skin's waste compost is expected to increase the growth and yield of edamame soybean. This research was conducted in Kp. PasirVillage Cinta karya Samarang District Garut Regency. Conducted in October-December 2016. Using factorial randomized block design (RBD) with 2 factors. The first factor, particle size of 2 levels are (a1) coarse particle size of coffee compost (> 74 μ) and (a2) fine particle size of coffee compost (< 74 μ). The second factor, dosage consisting of 4 levels 5 t ha-1 (t1) or 20 g plant-1 , 10 t ha-1 (t2) or 40 g plant-1 , 15 t ha-1 (t3) or 60 g Plant-1 , 20 t ha-1 (t4) or 80 g plant-1 to obtain 8 combinations of treatment level and repeated 4 times. Treatment (a2) fine particle size of coffee compost (< 74 μ) and dosage of (t4) 20 t ha-1 or 80 g plant-1 had an effect on the height parameters of the plant at 7-21 HST with the highest yield average 13.72 cm, 22.48 cm and 34.58 cm, particle size treatment and coffee skin's compost dosage influenced independently that is plant height at 28 days after plant, the shoot root ratio, the number of seeds per crop, the number of pod per crop and pod weight. Coffee leather waste compost can be used as organic fertilizer for soybean plants. Compost size <75 μ can be done to facilitate nutrient absorption for plants.

Each unit was repeated three times. The growth parameters observed were plant height, dry plant weight, number of pods, and pod weight per plant. The data from observations were then analyzed using analysis of variance at 5% significance level and then followed by Duncan’s test at 5% significance level. The results showed the application of chicken manure 20 t ...

Pupuk urea merupakan pupuk anorganik yang digunakan sebagai pupuk N. Penelitian bertujuan untuk mengetahui respon pertumbuhan dan hasil tanaman buncis (Phaseolus vulgaris L.) terhadap kombinasi pupuk guano kelelawar dengan urea. Penelitian dilaksanakan Desa. Ciaro, Kec. Nagreg, Kab Bandung. Rancangan percobaan menggunakan RAK. Percobaan terdiri dari 12 kombinasi yaitu: A = (6 t GK + 50 kg urea) ha-1 , B = (12 t GK + 50 kg urea) ha-1 , C = (18 t GK + 50 kg urea) ha-1 , D = (24 t GK + 50 kg urea) ha-1 , E = (6 t GK + 100 kg urea) ha-1 , F = (12 t GK + 100 kg urea) ha-1 , G = (18 t GK + 100 kg urea) ha-1 ; H = (24 t GK + 100 kg urea) ha-1 , I = (6 t GK + 150 kg urea) ha-1 , J = (12 t GK + 150 kg urea) ha-1 , K = (18 t GK + 150 kg urea) ha-1 , dan L = (24 t GK + 150 kg urea) ha-1 , tiap perlakuan diulang 3 kali. Uji lanjut menggunakan DMRT. Hasil penelitian menunjukkan kombinasi guano kelelawar dengan urea berpengaruh nyata terhadap tinggi tanaman, jumlah klorofil, umur berbunga, bobot segar polong per tanaman, dan bobot kering polong per tanaman Perlakuan L memberikan respon yang paling baik terhadap semua parameter.

Effectiveness of concentration of rice husk silica extract on growth and yield of sweet corn (Zea mays saccharata Strut). Bulg. J. Agric. Sci., 28(1), 61–68 Most of the soils in Indonesia are acid soils, which result in low availability of silica (Si) in the soil. Corn is a plant that responds to Si’s availability in the soil so that the application of exogenous Si in corn cultivation is an alternative solution in increasing productivity. This study aims to test the effectiveness of the exogenous Si concentration derived from rice husk silica extract (RHSE). This study used an experimental research method using a randomized block design, consisting of six (6) treatments = without RHSE, B = 10 ml l-1, C = 20 ml l-1, D = 30 ml l-1, E = 40 ml l-1 and F = 50 ml l-1 RHSE. Each treatment was repeated four (4) times to obtain 24 experimental units. Growth parameters and yields observed and measured during the study...

Waste produced by fish such as food and metabolic waste (feces and urine) can use as fertilizer for plantsthe water which contains food and metabolic waste furthermore flowing to planting media and plant absorption the nutrient so the water quality can reuse for fish culture. The objective of this study was to determine the effect of planting media on the growth and yield of red lettuce plants in aquaponics. Design experiment use nested completely randomized design. The data analysis using ANOVA, and the Duncan Multiple Range Test. The experiment consists of 3 treatments and nine replications. Media planting are rice husk charcoal, zeolite, and cocopeat. The results showed that the rice husk charcoal and zeolite substrate significantly affects number of leaves, fresh weight, and dry weight compared to cocopeat media. The red lettuce using zeolite as planting medium showed that higher growth of plant compared to plants with other types of substrate medium

The aim of this research was to find out the level of concentration of betle leaf extract as an hen’s egg soaker produce thes longest shelf life terms of haugh unit value, albumen index, and yolk index. This research used an experimental method with a Clompetely Randomized Design. There were five kinds treatments concentration level of betle leaf extract (P1=0%, P2=15%, P3=30%, P4=45%, P5=60%) with four replications. Duncan multiple range test were held to find the difference between any treatment in this research. The result of the research shows the use of betle leaf with the concentration level of 60% produce the longest shelf life 34 days in term haugh unit value, 32,75 days in terms of albumen index value and 34 days in term of yolk index value.

A fieldpolybag trial had been carried out at 750 m above sea level using a randomized block design two factors with factorial pattern and three replications. The first factor was the type of AMF (control, Glomus sp, Gigasporasp, Acaulospora sp. Glomus sp+ Gigasporasp+ Acaulosporasp). The second factor was the type rhizobacteria (control, Pseudomonas diminuta, Bacillus alvei). The results showed that AMF and rhizobacteria independently did not influenced soil bulk density, soil water content, and soil aggregate stability index. Gigasporasp increased harvest index and fruit fresh
