Abstract

Indonesia is recognized as one of the leading shrimp-producing countries globally, with most farms operating on a small scale using traditional methods. This creates a strong demand for low-cost technologies to support aquaculture. One critical component in shrimp farming is water quality monitoring, where salinity is a key parameter affecting shrimp health and growth. Affordable salinity sensors using iron electrodes are increasingly considered. However, they often produce unstable and fluctuating readings, compromising monitoring reliability. This study addresses the issue by applying digital filters to enhance the stability of salinity sensor data. Two filtering methods, Moving Average and Kalman filters were evaluated using salinity ADC data from previous research. The analysis focused on comparing their effectiveness in stabilizing measurements. Results show that the Moving Average filter outperformed the Kalman filter, providing lower standard deviation values (87,09, 65,69, 63,67) and variance values (7,5807E+03, 4,3150E+03, 4,0542E+03), confirming its suitability for improving low-cost salinity sensor performance.

Abstract

Botanical pesticides are naturally occurring chemicals derived from plant sources such as leaves, flowers, roots or seeds. This material has the potential as a more environmentally friendly and sustainable alternative to chemical pesticides. In general, residents in Mangaran Village, Mangaran District, Situbondo Regency work as farmers. In controlling pests and plant diseases, chemical pesticides are usually used to overcome them. The negative impact of using chemical pesticides is that pests will become increasingly resistant to the pesticides given, so stronger pesticides are needed the stronger the attacking pests. This resulted in an increasing number of chemicals in the crops that farmers planted which had an impact on the health of both farmers and consumers. The purpose of this socialization regarding vegetable pesticides is to increase knowledge regarding the manufacture of natural pesticides to control pests and diseases in plants. The socialization and training that was carried out received enthusiasm from farmers and those who attended the socialization were 26 farmers represented by each hamlet. The socialization results obtained are encouraging farmers to produce vegetable pesticides and reduce dependence on chemical pesticides

Abstract

This study assesses telecommunications infrastructure and traffic engineering in Raja Ampat, Indonesia, comprising four main islands and over 1,500 smaller islands across 46,000 km² of marine protected area. Field measurements at 48 points over 2023–2024, combined with QoS evaluation and SWOT-based assessment, revealed adequate signal coverage (–65 to –80 dBm) only within 1 km of shore-based stations, degrading to –95 to –110 dBm at offshore diving locations (5–15 km), where throughput dropped to 2–5 Mbps against the 10–50 Mbps requirement. A Modified Erlang B Model showed 3–4× seasonal traffic variation, with peak busy-hour demand reaching 2.5–4 Gbps from 300–560 concurrent users and the Misool–Salawati backhaul reaching 95% utilization. Capacity forecasting (R² = 0.91) indicates saturation within 2–3 years. An integrated approach combining additional base stations, expanded backhaul, LEO satellite integration, and renewable energy is essential.

Abstract

Maintaining body stability is a key challenge for hexapod robots in stair navigation. This study proposes an inverse kinematics (IK)-based approach for dynamic balance control using real-time joint angle computation. Experimental results show that the method maintains body orientation near a neutral position, achieving a minimum pitch angle of 7.3°, thereby improving stability and reducing mechanical collision risk. System performance is also influenced by actuator speed and battery voltage.
