Abstract

In Indonesia, one of the government's programmes is village electricity. For remote villages in mountainous areas, the construction of micro-hydro power plants is one of the answers to the government programme. Power generation in this way is very suitable for our country, given the natural conditions consisting of many mountains that have streams of river water. In turbines we recognise various types of turbines used, we can use francis, kaplan and pelton turbines. The use of these turbines depends on the potential head owned, Pelton turbines that use the principle of impulse require a relatively high head. In this study, it will be studied how the effect of nozzle angle variation and the number of blades on the performance of pelton turbines. The test results show that the tilt angle 65° produces higher rotation at 900-910 rpm while the tilt 90° produces lower rotation around 800-880 rpm. While the effect of the number of blades used is not so significant in the performance of pelton turbines, it can be seen in the use of the number of blades 9 and 18 at the tilt 65° nominal rotation that occurs around 900-910 rpm.

Abstract

The objective of this study is to optimise the productivity of soybean production through the integration of agricultural technologies inside plant monitoring systems. The objective of incorporating technology is to enhance the monitoring and management processes of soybean crops, with the ultimate goal of improving productivity and boosting harvest yields.This paper presents a proposal for the use of diverse agricultural technologies, including soil sensors, environmental sensors, drones, and data analysis based on artificial intelligence. Soil and environmental sensors are utilised for the purpose of monitoring soil conditions, moisture levels, and weather conditions in the vicinity of soybean agricultural fields. Drones are employed for comprehensive terrestrial surveillance and prompt identification of botanical concerns. The utilisation of artificial intelligence in data analysis involves the processing of information gathered from sensors and drones, enabling the provision of real-time insights and recommendations to farmers.By incorporating these agricultural technologies, it is anticipated that farmers would be able to effectively and efficiently utilise resources such as water, fertilisers, and pesticides, ensuring optimal usage in terms of precision and timeliness. Furthermore, the implementation of precise monitoring techniques and prompt responses to alterations in plant conditions within agricultural settings can effectively mitigate the potential hazards associated with crop loss resulting from pest or disease infestations.

Abstract

This community service activity aims to integrate Internet of Things (IoT) technology into the monitoring system of a Microhydro Power Plant (PLTMH) in Argamukti Village, Majalengka Regency. The village has significant renewable energy potential, but challenges in real-time energy production monitoring have hindered the plant's optimal performance. By implementing an IoT-based monitoring system, the operational efficiency of the PLTMH can be significantly improved. This program includes training in IoT device installation and guidance for local communities in operating and maintaining the system. The results show a 20% increase in energy production efficiency compared to the period before the monitoring system was implemented. Furthermore, the local community is empowered to manage energy resources independently, supporting the establishment of Energy Self-Sufficient Villages. This initiative aligns with government efforts to promote renewable energy usage in rural areas. The IoT technology implementation also opens opportunities for applications in other sectors such as smart farming and water management, which can sustainably enhance the local community's welfare.

Abstract

Hydram pump is a solution to overcome the problem of water demand, especially for highland areas. Hydram pumps can be used for rice field areas because they do not require an electric energy source. Operating parameters at the hydram pump greatly affect the efficiency of the hydram pump. In practice in the field, altitude is not difficult to obtain, especially for mountainous areas. However, for some highland areas, often to get a certain height must be with a large elevation distance hydram pump to water sources. In this research, a change in the angle of inlet variation will be conducted on the efficiency that occurs. So that with this research, it can be a benchmark for determining the distance of a hydram pump to a water source. The highest water discharge that can be generated from a 1 in size PVC hydram pump, 2.75 m inlet height, 5 m outlet height is 1.5 x 10-5 m3/s. while the lowest water discharge in the test carried out is 0 m3/s at the number of pendants 1 and the pump inlet angle is 45°. The inlet angle greatly affects the resulting flow rate. The inlet angle of 30°  results in a higher water flow rate of 1.44x10-5 m3/s at the number of pendulum 2 compared to the 45°  inlet angle which only gets 9.44x10-6 m3/s even up to 0 m3/s at the number of pendulum 1.

Abstract

One economical alternative to building a small-scale hydroelectric power plant is to use pumps as turbines, often referred to as PATs, which stands for Pump As Turbines. This research was conducted with an experimental method using a factorial experiment 22 After conducting research and data processing, Angle of Entry of Pump As Turbines and impeller tip angles Factors on turbines are equally influential to increase the speed of turning Pump As Turbines (PATs), but the variables the most influential in this study to increase the rotational speed of Pump As Turbines is the entry angle of PATs. Based on data processing to find the most influential variable using the Yates algorithm, if changing the PATs Entry Angle from 45° to 90° there will be an increase in Pump As Turbines rotational speed of 30.1 rpm while changing the impeller tip angles from 40° to 30° can only increase the Pump As Turbines rotational speed by 18.6 rpm. The alternator capacity that can be produced by Pump As Turbines is 100W, based on electrical power testing using a load of incandescent light bulbs. The electric power that can be generated by Pump As Turbines uses test samples at optimum conditions, namely the 90° Angle of Entry and the impeller tip angle 30° at the water pressure from the input pump 0.375 bar (g). The results of loading given using incandescent light bulbs with the power of 5 W, 10 W, 25 W, 40 W, and 100 W, there is the lowest voltage that is 194 V on a light bulb with 100 Watt power with alternator rotational speed of 855.7 rpm in the 3rd experiment.
