Rubber (Hevea brasiliensis) is a leading commodity in South Sumatra, but as the plants age, their productivity declines, no longer providing optimal profits. This condition has prompted plans to convert old rubber land into oil palm plantations, which requires an evaluation of soil physical property suitability. This study aims to analyze the condition of several soil physical properties (color…
This study was conducted in Batanghari Leko District, Musi Banyuasin Regency, specifically in Tanah Abang Village and Talang Leban Village. The objectives of this study were to analyze the differences in household income between farmers who converted rubber land into oil palm during the immature plant phase (TBM) and farmers who did not convert their land, and to identify the survival strategie…
Plastic bottle waste is one of the environmental problems that continues to increase due to the high use of single-use plastics in everyday life. This final project aims to design and develop a technology-based plastic bottle waste reverse vending machine to support an automated waste management process. The system uses an ESP32 microcontroller as the main control unit, equipped with a TFT LCD …
The increase in plastic waste, especially plastic bottles, is influenced by the high consumption of packaged beverages, while the processes of data collection and recording are still not optimally structured. This system was designed to develop the Plasticpay Point System dashboard integrated with a plastic bottle Reverse vending machine, where each inserted bottle is detected by an ESP32-based…
The decreasing availability of clean water due to population growth, industrial activities, and environmental pollution has encouraged the development of more effective water treatment technologies. One of the widely used technologies is Polyethersulfone (PES)-based filtration membranes because of their excellent thermal stability and chemical resistance. However, the hydrophobic nature of PES …
