Abstract

The main feed for ruminants is forage, and its supply fluctuates greatly depending on the season. During the rainy season, the forage will thrive and be abundant, but the opposite condition, i.e. dry season, where farmers will have difficulty getting fresh forage. Meanwhile, animal feed must be continuously available. The solution is to use agricultural waste as an animal feed with limiting factors, namely high lignin content, low digestibility, low protein content, and anti-nutrients. Therefore, a feed processing technology known as Ammoniation is needed. Ammoniation is a chemical treatment of agricultural and plantation waste feed ingredients by adding chemicals like NaOH, KOH, or Urea. Ammoniation can reduce lignin and silica and increase protein content. Socializing ammoniation technology in the Ambacang Permai livestock farmer group, Lima Puluh Kota District, was necessary. The method included lectures, demonstrations of making rice straw ammoniation, discussions, and consultations on animal feed. This activity was expected to help group members to overcome the problem of providing ruminants' feed from crop residues and plantation waste, so it was expected to reduce feed costs and increase group business.

Abstract

The Lubuek Kabau Sepakat farmer group is one of the farmer groups that actively cultivates strawberry plants. However, the strawberry production obtained is not optimal because of the lack of knowledge related to organic fertilizers and the source of planting material used is not clear about the origin of the variety because it is only vegetatively propagated from the previous plant. Therefore, the objectives of this service activity are 1) to educate farmer groups about ecoenzymes so that they can be used as one of the organic fertilizers to be applied to strawberry plants; 2) to provide seedlings of superior strawberry varieties so that the quantity and quality of strawberry production can increase. The activity was carried out at the Lubuk Kabau Sepakat Farmer Group, Nagari Batang Barus, Solok Regency, West Sumatra. The stages of activities carried out include: identification of partner needs and problems, preparation of programs that are in accordance with the needs / problems of partners, implementation of activities in accordance with the plans that have been made, then monitoring and evaluation. The result of this activity is that the partners' knowledge or skills related to ecoenzyme have increased so that they are able to independently produce ecoenzyme and will apply ecoenzyme to strawberry plants. A total of 150 strawberry seedlings of the premium Sweet Japanense variety have been delivered to partners so that the quantity and quality of strawberry production can increase. The results of the activity evaluation showed that 95% of the participants were very satisfied with the activities carried out by the service team. As many as 85% of participants said that this training activity was very useful in helping to reduce organic waste in the form of fruit peel residue. The relevance of themes and materials is in accordance with the needs and can be applied in everyday life.

Abstract

One of the efforts that can be done is to increase the national corn productivity by developing prolific composite corn varieties. This is done because prolific corn is a type of corn with a tendency to produce two or more cobs, so that it can increase the value of corn production. The purpose of this study was to obtain prolific corn candidates (two cobs) with high yield and uniformity. This research was conducted using the mass selection method. Mass selection is done by selecting plants that have the desired character, namely prolific corn (cob two). The observed variables were the diversity in the F4 population, the percentage of prolific maize, and the comparison of the yield components of prolific maize with non-prolific maize. This study succeeded in obtaining 50% prolific corn on the cob and has wide diversity criteria. Of the 561 prolific corn plants, there are 91 corn plants that are classified as productive prolific. Prolific maize has a higher yield component than non-Prolific maize. Seed weight with cobs on productive prolific corn reached 318 g and seed weight reached 268 g.

Abstract

Organic matter has an important role besides providing macro and micro nutrients to plants, it can also improve environmental quality. The fermentation of rabbit urine and coconut water is expected to optimise the growth of honje seedlings. The aim of this study was to determine the concentration of fermented rabbit urine and coconut water that can optimise the growth of honje seedlings of Tasikmalaya accession. The study used a completely randomised design with seven treatments, namely A = control, B = 25% rabbit urine fermentation, C = 50% rabbit urine fermentation, D = 25% coconut water, E = 25% rabbit urine fermentation + 25% coconut water, F = 50% rabbit urine fermentation + 25% coconut water, G = 50% rabbit urine fermentation + 50% coconut water. The results showed that the treatments gave significantly different results on shoot emergence, seedling height, seedling diameter, and root crown ratio. Treatment G produced the fastest shoot emergence (6 days), and plant height (10.4 cm). Meanwhile, the widest seedling diameter was produced by treatment B (4.4cm), C (3.9 cm), and treatment G (3.9cm). Treatment C produced the highest root crown ratio of 0.5.

Abstract

This research discusses the critical role of phosphatase enzymes in soil, particularly in the phosphorus cycle and soil fertility. Acid and alkaline phosphatases are identified as crucial components, with their activities serving as indicators of soil fertility. This study evaluates the soil chemical and biological characteristics in mangosteen orchards in the Mangosteen Thematic Village, specifically in monoculture and polyculture cultivation patterns on slopes ranging from 8-15%. Soil pH, organic C, available P, total P, soil respiration, microbial C-biomass, and phosphatase enzyme activities were assessed at 0-20 cm and 20-40 cm depths. Total P did not show significant changes based on cultivation patterns. The results show that the soil pH values tend to be acidic to slightly acidic (5.21- 5.45) with no significant differences based on depth. Organic C, available P, soil respiration, microbial C-biomass, and acid phosphatase enzyme activity were higher in polyculture cultivation patterns but alkaline phosphatase enzyme activity was higher in monoculture. The cultivation pattern influences the dynamics of agricultural ecosystems and should be considered in land management to enhance productivity and soil ecosystem balance.

Abstract

Acacia gum produced from Acacia mearnsii is a natural material with great potential for various industrial applications due to its unique physicochemical properties. This study aimed to characterize gum acacia from Alahan Panjang, West Sumatra. Characterizatio was done using Fourier Transform Infrared Spectroscopy (FTIR), X-ray fluorescence (XRF), and X-ray diffraction (XRD) techniques. FTIR results revealed the presence of hydroxyl (-OH), carbonyl (-C=O), and glycosidic (C-O-C) groups, indicating the complex polysaccharide structure of the gum. XRF analysis showed the dominance of calcium oxide (CaO) with a concentration of 81.652%, followed by potassium oxide (K₂O) at 10.052% and phosphate (P₂O₅) at 6.341%. Meanwhile, the XRD diffraction pattern identified a near amorphous diffraction with some weak crystalline peaks. This combination of results suggests that gum acacia has chemical and physical properties that support its use as an emulsifier, thickener, and filler in various industries, such as food, pharmaceutical, and cosmetics.
