Abstract

Red chili is cultivated practically everywhere and plays a crucial role in Indonesian culture, economy, and cuisine. Plant diseases have been the main factor driving the country’s yield reduction of red chili. This research was conducted to observe chili plant diseases in Hargobinangun Subdistrict, Pakem District, Sleman, Yogyakarta. Chili variety Twist-42 was planted in the area. The Twist-42 variety is a local variety that is well adapted in the middle plains between 450 – 650 masl (meters above sea level) and is a good variety in both the dry and rainy seasons. There were 360 red chili plants as samples. The diseases found are Yellow leaf curl disease, Anthracnose, Ralstonia wilt, and Root knot nematode (Meloidogyne spp.).

Abstract

Low-rank coals, such as lignite and sub-bituminous coal, generally exhibit low calorific values (< 5,100 kcal/g, air-dried basis) and high moisture content (30-50%). This high moisture makes them less attractive and difficult to market, despite their abundance in Indonesia. Additionally, these coals are prone to spontaneous combustion, requiring special handling. Given their high moisture and sulfur content, they are inefficient as fuel and contribute to gas pollution, necessitating costly emission controls. This study, conducted in collaboration with Universitas Pembangunan Nasional Veteran Yogyakarta, explores the use of fine coal as a fertilizer additive. The research aims to evaluate the effectiveness of fine coal in urea fertilizers and analyze its humic acid content. Fine coal was tested as an additive in urea fertilizers at ratios of 3:1, 1:1, and 1:3 on pakcoy, kangkung, and tomatoes. The 1:3 ratio of urea to fine coal proved most effective, enhancing plant growth and leaf quantity. Results suggest fine coal, a byproduct from PT Adaro Indonesia, can be effectively used as a fertilizer additive, contributing to waste reduction. However, humic acid analysis revealed it does not yet meet standard fertilizer quality requirements, indicating a need for further improvement. Keyword: Low-rank coals, Fine coal, Fertilizer additive, Humic acid, Plant growth

Abstract

Weed vegetation refers to plants that grow in agricultural land, gardens, or other environments that are undesirable to humans. The aim of the research was to analyze weed composition and determine the value of weed diversity in teak plant stands and sengon plant stands. Analysis of weed vegetation on land with the SDR coefficient value of weed species, to see differences in weed composition between two stands using a community index. The research was carried out in Sumber Girisuko Village Panggang District, Gunungkidul Regency. Determining the research location used the purposive sampling method and weed sampling using systematic random sampling, while the analysis method used the quadratic method. The results obtained show that in this study 10 weed species were found from 6 families, namely Passifloraceae, Colchicaeae, Asteraceae, Poaceae, Convolvulaceae, and Verbenaceae. In the land under teak stands, 5 species were found with SDR values of 0.03-0.61, in land under sengon stands there were 8 species with SDR values of 0.02-0.48. The value of the community coefficient for the land under the teak and sengon stands was 16%, meaning that the weeds on the two lands were not uniform. The diversity index (H') value for land under teak stands is 1.10 and for sengon stands is 1.52, which means it is classified as moderate. The Simpson dominance index was found to be 0.40 in land under teak stands, and 0.27 in sengon stands, meaning that weed species were present but did not dominate.

Abstract

The purpose of research was to examine the effect of gold snail liquid organic fertilizer and organic planting media on eggplant growth and yield. The research is a field experiment prepared with RAKL. The first factor in the gold snail liquid organic fertilizer is 40 ml/L, 80 ml/L, and 120 ml/L. The second factor is the addition of planting media namely 20 kg/plot sawdust, 20 kg/plot cocopeat, and 20 kg/plot husk charcoal. Data were analyzed using ANOVA 5% level and further tested using DMRT 5% level and orthogonal contrast test. The results showed that there was an interaction between the treatment of gold snail liquid organic fertilizer concentration and organic growing media. The best combination in the treatment of 120 ml/L gold snail liquid organic fertilizer concentration with 20 kg husk charcoal planting media/plot against the stem diameter parameter of 35 days after planting and the best combination in the treatment of 80 ml/L gold snail liquid organic fertilizer concentration with sawdust planting media 20 kg/plot against the fruit weight parameter per hectare. The addition of cocopeat planting media of 20 kg/plot shows a heavier fruit weight value per fruit compared to the addition of husk charcoal planting media 20 kg/plot.

Abstract

This study aims to analyze optimal combination of inputs, labor, machines and demand for wedang uwuh (original, brewed, and instant) which provides an optimal combination of wedang uwuh production in CV. Progress Jogja. This research uses descriptive method with case study method and the director and production manager as respondents. The types and sources of data are primary and secondary data. Collecting data uses observation, interviews, and documentation method. The data analysis technique uses a Linear Programming (LP). The results showed that there was an optimal combination of input used namely rock sugar, demand for wedang uwuh seduh, and demand for instant wedang uwuh. The combination input such as dry ginger, wet ginger, granulated sugar, nutmeg leaves, sappan wood, clove leaves, labor, machines (cabinet dryer, grinder, grate, spinner, crystallizer) and the demand of original wedang uwuh did not optimal yet

Abstract

Most drying processes in Indonesia still utilize heat from direct sunlight. However, this method is deemed less effective because it is very dependent on the intensity of sunlight (weather) and the time required tends to be long. A drying tool is needed as an alternative that can be used to save drying time. This research aims to determine the efficiency of electrically powered drying equipment using citronella as an agricultural product that is abundant and easy to find. The variables used in this research are material weight with variations of 10, 15, 20, 25, 30 grams and drying time with variations of 10, 15, 20, 25, 30 minutes. The test methods used were air content testing, drying rate testing, mass flow rate testing and drying equipment efficiency testing. The results of the tests that have been carried out, obtained optimal results for the citronella material, namely with a weight variation of 10 grams over a period of 5 hours with the lowest water content of 2%. The efficiency of the electric power dryer was obtained at 65.62%.
