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

Land evaluation is the process of assessing the appearance of land for a specific purpose, including conducting and interpreting surveys and studies of land forms, soils, vegetation, climate, and other land aspects in order to identify and make comparisons of various land uses that might be developed. The aims of this study were: to determine land suitability classes and their management for cassava in the Gufasa watershed of Dodinga Village, South Jailolo District, West Halmahera Regency. This research took place from October to November 2021. Evaluation of land suitability refers to the FAO land suitability classification system (1976) to the category of land suitability units. There are two land suitability conditions presented, namely actual land suitability (A) and potential suitability (P). The actual land suitability for cassava plants in the Gufasa Watershed of Dodinga Village is suitable (S) with an area of 496.6 Ha (35.21%) and not suitable (N) with an area of 913.6 Ha (64.78%) with limiting factors, namely very obstructed drainage, flooding heavy (flood hazard), rough texture, heavy erosion and slopes 15%. Suitable land (S) is divided into two classes, namely quite suitable (S2) with an area of 108.0 Ha (7.6%) with a limiting factor of rainfall, rather fine texture, low total N, and mild erosion and marginally suitable (S3) with an area 388.6 Ha (27.55%) with a very low limiting factor of N-total and slope. Potential land suitability for cassava plants if efforts to improve the land limiting factors are obtained that are suitable (S) of 360.8 Ha (28.31%) and unsuitable (N) of 913.6 Ha (7.15%).Keywords: Land suitability, land characteristics, soil quality, limiting factors

Abstract

Signs of soil that has undergone advanced development include clearer horizons, higher fine fraction and lower coarse fraction, brighter soil color, higher levels of free Al and Fe. Soil aggregation is increasing, to a certain extent organic matter and nutrient levels are increasing as well as CaCO levels, and soluble salts. Soil development is characterized by the occurrence of horizon differentiation as a representative of the process of change in the earth's skin both physically, chemically and biologically by reactions in the soil profile there is an addition of organic and mineral materials in the form of solid, liquid or gaseous materials, the disappearance of materials above the soil, the transfer of materials from one part to another in the soil body, the transfer of the form of mineral compounds and organic matter in the soil body This research was carried out in the village of Bobaneigo Madihutu, South Jailolo District, West Halmahera Regency from June to July 2023. The method used in data collection is a free survey method, which is an observation made directly in the field by determining the research location based on land use maps, and administrative maps. The variables observed were C-Organic, N-Total, C/N Ratio, CEC, KB which are soil chemical properties. The results showed that the study of the level of soil development in several types of land use has not experienced weathering or advanced development due to the low content of nutrients.

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

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
