Abstract

Village in Ternate City has the potential to be developed as an agricultural area because the soil type is Inceptisol which is suitable for agriculture. The ability of the soil to pass water, or what is commonly called soil permeability, is one of the important components for agricultural land management. Soil structure and texture as well as other organic elements play a role in increasing the rate of soil permeability. This study aims to understand soil permeability and soil water content in Gambesi. Samples were taken at a depth of 0-20 cm (Layer I) and 20-40 cm (Layer II) on three types of land use: residential areas, mixed dry land, and clove and nutmeg plantations. Soil sampling technique used purposive random sampling method. Identification of soil properties in the field is carried out using drill identification techniques, sample rings and profiling. Parameters observed were permeability, percent soil moisture content, specific gravity, particle density and soil texture. The results showed that the soil in each layer and type of land use had a variable permeability rate of 0.63-1.91 cm/hour, with a soil moisture content of 21.6-30.43%, a density of 1.01-1.91 cm. 1.23 gram/cm3, particle density of 2.0-2.27 gram/cm3, and porosity of 39.40-55.41%. The soil texture is sandy loam and sandy clay loam. The rate of soil permeability based on land use type has a rather slow permeability class, while the soil water content is at a permanent wilting point condition.Keywords: Bulk density, particle density, porosity, soil permeability, and soil water content

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

Abstract Farming communities have not utilized agricultural waste and animal waste as compost optimally in overcoming the scarcity of fertilizer in farming communities. Composting is an alternative way of creating natural fertilizer made by farmers themselves, thus responding to the scarcity of fertilizer which in turn improves the health quality of the soil, produces healthy plant products, and increases farmers' income. The solutions offered in the program include the presentation of compost making materials, how to apply them to plants, assistance in plant cultivation business activities, post-harvest handling so that plant products can be maintained in a healthy manner. It is hoped that the farmers as partners who are accompanied can produce organic compost fertilizer which can increase crop production and increase their income. The aim of this program is to improve farmers' skills in utilizing plant litter, agricultural waste, animal waste to make compost fertilizer, which can then be sold on the market or used by farmers themselves to improve their vegetable cultivation business. Stages of activities include socialization, presentation of counseling material, creation of compost demonstration plots and plant cultivation demonstration plots with stages of land preparation, seeding, making plots, planting, fertilizing, watering, maintaining plants until harvest and marketing the results of cultivated plants.

Abstract

Banana peel waste is a source of environmental pollution because it will rot and cause an unpleasant odor and disrupt the cleanliness of the surrounding environment if it is not processed immediately. Therefore, the use of organic fertilizer from banana peel waste is an important step to overcome this problem. This research was conducted in Tabona Village, South Ternate. The method used in this research was a randomized block design (RAK) consisting of 5 treatments, namely (P0) without control, (P1) banana peel waste 10 tons/ha), (P2) banana peel waste 20 tons/ha), (P3) banana peel waste 30 tonnes/ha and (P4) banana peel waste 40 tonnes/ha. Each treatment was repeated 4 times so that the number of experimental units was 5x4 = 20 experimental units. The results of the research show that the application of organic fertilizer from banana peel waste can provide changes in several physical properties of inceptisol soil, namely soil volume weight, soil porosity, soil organic C, % soil water content and soil permeability, stability of soil aggregates.Abstract.

Abstract

East Halmahera is the main area for developing rice and beef cattle in the North Maluku region. The cultivation of food crops and livestock production generates substantial waste which requires proper management. Precise waste management can reduce environmental pollution in agricultural areas while creating added value opportunities. Rice waste is used with cow manure to produce biogas and organic fertilizer through anaerobic digestion technology. In this research, rice waste and cow dung were used to produce biogas and organic fertilizer through anaerobic digestion. The research is a continuation of previous studies on biogas production in a laboratory setting. The study is divided into two stages: firstly, the production of biogas, and secondly, the creation of organic fertilizer from the remaining bioslurry. The performance of a Modified Profile Anaerobic Reactor biogas digester was evaluated using standard parameters such as pH, temperature, total solids, and flame duration. The nutrient content of the organic fertilizer was tested based on various parameters, including C-organic, Nitrogen (N), C/N ratio, Phosphorus (P2O5), and Potassium (K2O). The results of the research showed that a biogas reactor with a capacity of 2.200 kg produced 4.2 kg of biogas with a flame duration of 12 hours, 7 minutes, and 10 seconds. The average temperature during the process was 29°C, and the total solid organic material decomposition was 33%. Total solid processed organic fertilizer with a C/N value of 16.53, C-Organic content of 24.16%, macronutrients N 1.93%, P2O5 0.37%, and K2O of 1.75%.Keywords: biogas, organic fertilizer, rice husks, cow dung, and East Halmahera.
