Abstract

Organic materials refer to substances derived from plant or animal waste and by-products, including manure, composted rice straw, plant residues, sewage, green manure, legume cuttings, and municipal or industrial waste (Zaini et al., 2004, cited in Pirngadi, 2008). This study aims to assess the level of organic material availability and identify the factors influencing it. The parameters analyzed include soil pH, total nitrogen (Total-N), organic carbon (C-organic), organic materials, water content, and the C/N ratio. The research was conducted in Subaim, Bumi Restu Village, in the Wasile District of East Halmahera Regency.The calculation of organic material values involved multiplying the C-organic content by a factor of 1.74%. The findings reveal that the average organic material content across various types of rice field land uses ranges from moderate to high, specifically between 4.12% and 4.43%. The higher levels of organic materials are attributed to the application of rice straw and organic fertilizers during post-harvest and land preparation phases. Conversely, lower organic material values are primarily due to the significant consumption of organic matter by plants during their growth stages

Abstract

ABSTRACT Fruit peel waste is an organic waste material which is solid waste which, if left untreated, can cause an unpleasant odor and disrupt the comfort of the surrounding environment. Many people have used waste from fruit peels, such as making compost or organic fertilizer and so on. One use of waste from fruit peels is to use it by making ecoenzymes. The enzymes produced from fermentation are a waste management method that utilizes kitchen scraps to produce something very useful. Ecoenzymes can be used as multifunctional liquids and their applications include households, agriculture, animal husbandry, and even in the health sector. The fruit peel waste used in this research was pineapple, papaya, orange, mango and watermelon. The aim of this activity is to improve the skills of farming groups in making ecoenzymes by using pineapple, papaya, orange, mango and watermelon peels which are applied to mustard plants as liquid fertilizer. The result of this activity is that the training participants have relatively the same perception and understanding and are able to independently make ecoenzymes and apply them to soil, plants and the environment in general. Keywords: Ecoenzymes, pineapple, papaya, orange, mango, watermelon

Abstract

Forest and land rehabilitation (RHL) is a strategic program of the government in the field of forestry development. RHL aims and objectives to restore, maintain, and improve the function of forests and lands to be maintained. The study aimed to analyze the impact of RHL activities in the Tosoa Micro Watershed and the Ake Leije Mata Sub-Watershed Tuguaer, South Mother District, West Halmahera Regency. The assessment of planting success was carried out with a systematic sampling technique with random start with a sampling intensity of 5% on each planting plot at the Micro Watershed RHL site. The plant assessment plot is rectangular (40 m x 25 m) with a distance between the measuring plots for the North – South direction of at least 200 m while the East – West direction is at least 100 m. The data collected is in the form of primary data and secondary data. Data on the assessment of planting success were analyzed by descriptive and estimating methods. The results of the analysis are classified into the criteria for successful planting, while the impact analysis shown to determine erosion and sedimentation.  The results showed that in general, the success rate of planting in the Tosoa and Tuguaer RHL Micro Watersheds carried out in 2019 - 2021 was classified as successful. The percentage of successful planting in the Micro RHL watershed of the Tosoa protected forest block and Planting Monument (P0), First Year Maintenance (P1), and Second Year Maintenance (P2) respectively was 82.27%, 79.55% and 76.08%. The average growth of RH plants in the Micro watershed of the Tosoa protected forest block and Planting Tuguaer (P0), First Year Maintenance (P1) and Second Year Maintenance (P2) respectively by 49 cm, 52 cm and 55.16%. Prediction of Erosion Value in the Tuguaer Block RHL Micro Watershed (145.57 tons / ha / th); and the Tosoa Block (90.59 tons/ha/th) and the predicted sediment value of the Tuguaer Block (50.89 tons/ha/th); and Tosoa Block (24.41 tons/ha/th).Keywords : Rehabilitation, Success, Micro Watershed, Erosion, Sedimentation.

Abstract

Appropriate land management has a long-term impact on soil performance and is believed to improve soil fertility. This study investigated the effect of eco-enzymes on soil nutrients and plant productivity of green mustard-peanut in inceptisol. The research was conducted from February to April 2025.  The experiment used a randomized block design (RBD) consisting of 5 treatments and replicated 3 times, so that there were 15 units, including N0 = without Eco-enzyme, N1 = Eco-enzyme 2cc/L. N2= Eco-enzyme 4cc/L, N3= Eco-enzyme 6cc/L, and N4= Eco-enzyme 8cc/L. The commodities used were green mustard (Brassica juncea L) and peanut (Arachis hypogaea Linn). Soil properties variables included soil pH, N-total, and P-available, while plant productivity variables included plant height, number of leaves, leaf area, fresh weight, and pod production. The results showed that the concentration of eco-enzymes had a significant effect on N-total, P-available, green mustard plant height, and peanut plant height. However, eco-enzyme concentration had no significant effect on soil pH, number of green mustard leaves, green mustard fresh weight, green mustard leaf area, number of peanut branches, and peanut pod production. The lowest production of green mustard was 0.85 tons/ha, and the highest was 3.29 tons/ha. While the lowest production of Peanut pods was 4.3 tons/ha and the highest was 6.67 tons/ha.

Abstract

The development of mangrove ecotourism is one of the efforts to utilize environmental services from coastal areas sustainably. Ecotourism in mangrove forests is seen as being able to synergize with real forest ecosystem conservation measures. The purpose of the study was to determine the suitability of community-based mangrove ecotourism land in Lelilef Waibulan Village, Weda Tengah District based on ecological, socio-economic and supporting aspects. Data collection procedures include observations of biophysical conditions (mangrove vegetation, biota objects, tides), interviews with interviews using Purposive sampling techniques. The results of the study obtained the mangrove forest area of Lelilef Waibulan Village is very suitable to be developed as a mangrove ecotourism area both from ecological, socio-economic and supporting aspects.
