Abstract

Compost fertilizer is very influential on the nutrient status of the soil and plants. Giving compost fertilizer will also have a good effect on the growth and development of mustard plants. This study aims to determine the effect of the addition of biostarter on compost fertilizer to N-total and N nutrient absorption on mustard plants. The experiment was structured using factorial randomized group design. The method in this study using compost analysis,soil analysis, and plant analysis. The results showed that the nine samples have different nutrient content and nutrient nutrient absorption resulting in different effects on soil and mustard plants. Nitrogen in the soil greatly affects the N nutrient absorption on plants, the two parameters have a positive correlation which means directly proportional. Nitrogen absorbed by plants affects N-total levels in plants. N levels in plants and soil is very influential on the color of the leaves of mustard plants. Through the nutrient levels can be known proper fertilization recommendations for mustard plants. Based on the analysis of nutrient levels in soil and plants known fertilizer recommendations in nine samples with the addition of biostarter in kudzu compost and fertilizer doses.

Abstract

Water spinach (Ipomoea aquatica) is a plant that is included in the type of vegetables and is widely cultivated as food. Every year the demand for water spinach in the market continues to increase, besides that consumers also want the quality of water spinach which is more nutritious, clean, and hygienic. Therefore, hydroponic water spinach is used to support consumer demand in the market. In addition, by cultivating water spinach hydroponically as well as an alternative to farming in narrow areas. In hydroponic cultivating water spinach, there are several things that need to be considered, such as the provision of nutrition, the planting media used, and what hydroponic system will be used. This study aims to determine the response of water spinach plants to the treatment of different planting media, as well as to obtain information about what planting media is suitable for use in the DFT water spinach hydroponic system to support its growth and development. The experimental method used was a completely randomized design, which consisted of three different levels of treatment, namely the use of rockwool, charcoal, and moss media. The results of this study of differences in planting media showed the treatment with the best tendency for the parameters of plant height, number of leaves, and plant fresh weight

Abstract

Utilization of coffee skin waste as compost can reduce the use of chemicals in cultivation. The addition of the two materials to compost with various doses of urea and the number of earthworms (Lumbricus rubellus) is expected to help speed up the process of decomposing coffee husk waste into compost and can increase the nutrient content in the compost. Urea and earthworms are used as decomposition materials and enrich the NPK element in the coffee husk waste compost. The result of making organic fertilizer from coffee husk waste compost is in the form of granules. Granulating is done manually to provide innovation in organic fertilizers. The purpose of this study was to determine the best combination of urea and earthworms in improving the NPK nutrient quality of coffee husk waste compost. Research on coffee husk waste compost was carried out at the Green House and Soil Biology Laboratory, Faculty of Agriculture, University of Jember. The method used was a factorial completely randomized design (CRD) with 2 factors, namely earthworms (Lumbricus rubellus) and urea with 3 levels each. The data obtained were analyzed statistically using Analysis of Variance (ANOVA). If there is a data treatment that shows significantly different results, then the Duncan Multiple Range Test (DMRT) is carried out with a significant level of 5%. The interaction between the number of earthworms (Lumbricus rubellus) and the dose of urea in the composting of coffee husk waste has a very significant effect on several variables, namely; Moisture content, Nitrogen, Phosphorus, Potassium, C-Organic, and C/N ratio values, however, did not significantly affect the temperature and PH variables of coffee husk waste compost.

Abstract

The rise of illegal or unlicensed sand mining by irresponsible individuals has caused damage along the coast of Mawasangka District, Central Buton Regency. This study aims to identify the biophysical environmental impacts due to illegal sand mining in the coastal District of Mawasangka Buton and recommendations for post-sand mining land management. The method used in this study was direct observation to determine changes in the coastline and types of damaged vegetation, normalized difference vegetation index (NDVI) analysis to determine the density of vegetation on post-mining land, and measuring the depth of excavation. The results showed that there had been 321 m of beach abrasion and the types of vegetation damaged were coconut, acacisa and jaran wood trees. The results of the NDVI analysis show that non-green space around the mining area is 33.63 ha, while very low vegetation density is 41.91 ha, and low vegetation is 330.05 ha, while the rest is moderate and high vegetation covering 605.47 ha. Measurement of the depth of excavation ranged from 0.6 m – 2.3 m with good and moderate categories. Management of coastal post-mining land in the Mawasangkan sub-district is directed as pond land and revegetation.

Abstract

Industrial developments and increasing consumer concern for the environment and the issue of environmentally sound industrial concepts have forced the industry to adjust the concept of green industries in every business, including in procurement, which is better known as green procurement. Supplier selection is an important decision-making problem to get suppliers who can increase the company's competitiveness. This research was conducted in Jember regency to evaluate and select cassava suppliers based on green procurement using the AHP method. The criteria used are 6 criteria, namely quality, technology capability, pollution control, environment management, green product, and green competence. Each criterion has sub-criteria between 3 or 4 sub-criteria. The number of sub criteria is used to determine the RI value. The RI value is used to calculate the CR value of each criterion. The results of data processing show that the highest CR value is in the technology capability criteria and the lowest CR value is in environment management. The highest hierarchical criterion value for environmental management criteria is 0.273, because the selection of cassava suppliers can be expected to pay attention to environmentally sound controls.
