Abstract

Soil quality is an important factor in determining agricultural yields, and geological conditions also influence the availability and distribution of essential minerals for plant growth. Tamaila Utara Village, in Gorontalo Regency, has significant agricultural potential, but it has not been fully optimized. The objective of this study is to conduct an in-depth analysis of soil mineral content and geological conditions, as well as their impact on agricultural productivity. This study uses a combined approach of laboratory analysis and quantitative analysis with the Guttman method. Soil samples were collected at several agricultural sites, based on land slope, followed by an analysis of macro and micro-nutrient content. The results show that the volcanic rock-based geological conditions, rich in minerals, support the availability of nutrients in several areas. However, the farming practices for corn in Tamaila Utara Village are still unsustainable, as these activities have significantly impacted the surrounding ecosystem, soil quality, and corn yields, which have declined over the past three years.

Abstract

This study was conducted to comprehensively analyze household waste management and the effectiveness of TPS-3R in Gorontalo City. This analysis identifies the level of effectiveness of TPS-3R and the basis for formulating recommendations for sustainable waste management policies in the Gorontalo City area. This study was conducted on a sample population of 8 villages and 8 waste generation locations spread across the 8 villages and 4 TPS 3R located in 8 villages. Furthermore, this study uses Purposive sampling in determining the location based on the condition of waste generation, and data collection using the Checklist Form of waste generation and the condition of TPS 3R then interviews with the village government with the Guttman analysis approach for quantitative data for the Checklist Form and interview analysis using the Miles and Huberman approach for qualitative data analysis. The problem of waste generation and household waste management in Gorontalo City is still not optimal, where community involvement in preventing waste generation is not yet effective, facilities and infrastructure such as TPS-3R are not optimal in reducing waste generation due to several obstacles such as unclear management and institutions and the active role of the village government is not yet too strong due to the existence of waste management regulations from the region directly by the Environmental Service so that there needs to be clear coordination and collaboration in terms of law and regulations in the future.
