Abstract

Research using satellite imagery of gravity data has been conducted in the Dampit District, Malang Regency, East Java Province. This research was conducted to identify areas vulnerable to landslides. The results of this research can serve as a basis for the government to develop effective landslide disaster mitigation policies, thereby minimizing the losses incurred. The data used is TOPEX satellite gravity data in the form of Free Air Correction data, and supported by landslide vulnerable areas data from the InaRisk satellite. The research area is 23 km x 16 km with 2 km spacing between points and 184 measurement points. Furthermore, the research area is divided into four areas: Area A1, Area A2, Area A3, and Area A4.  The residual anomaly value in the study area is between 82.7 mGal to 142.4 mGal. The residual anomalies are more variable due to the local nature of the anomalies. The correlation between the residual anomaly value and InaRisk satellite image data shows that Area A4 is the most vulnerable to landslides, especially if there is a trigger such as an earthquake.  This is because Area A4 has a low-density value, a large fault, and is the contact area between the Mandalika Formation and Wuni Formation.

Abstract

Background: Farmers can market their crops due to the significant market share for hydroponic agriculture products. However, this presents a dilemma as the market demands a consistent supply of high-quality crops. Precise nutrient levels and controlled chemical-physics parameters are crucial considerations in hydroponic yields. Thus far, these factors have been managed manually, leading to challenges in achieving desired outcomes. Objective: This community service program aimed to address this issue by developing a real-time automated system for monitoring and controlling chemicalphysics parameters and nutrient levels via an Android application. The goal was to enhance the effectiveness and productivity of hydroponic crop harvests. Method: The program commenced with designing the system based on farmer requirements, followed by the installation and testing of equipment at partner locations. Subsequently, technical training on system features and usage was provided. Results: The system was successfully installed at Grahaponik. According to questionnaire responses, 68.4% of farmers expressed satisfaction, and 78.9% of total participants reported that the system was easy to employ. Technology installation, implementation, and dissemination to local hydroponic farmer groups were conducted. Hydroponic farmers acknowledged the user-friendliness of the devices. Conclusion: Partners' acceptance of the instruments was favorable, facilitating their ease of use and thereby enhancing the effectiveness of hydroponic farming.
