Abstract

This study focuses on the technical and cost analysis of an electric hand plow tractor, especially in the East Java region. The manufacturing cost of electric tractors increases significantly in line with the battery capacity. Although the manufacturing cost of an electric tractor is 3–5 times higher than that of a fuel tractor, the operational cost of an electric tractor is about 79% that of a fuel tractor. Based on the investment analysis, it is feasible to assembly electric tractors with a power of 5.5 HP or 4.1 kW using NMC18650 and NMC21700 batteries with an energy capacity of 14 kWh in case for rural residents with access to an electricity network available in their paddy fields. The price of electricity and the unit cost of a battery pack have a large impact on operational costs. The manufacture of electric tractors will be more attractive to get better economic returns when the price of electricity does not increase, and the unit cost of battery packs falls due to the battery technology trend. Nevertheless, certain challenges to the utilization of electric tractors are the farmers' preferences and habits, market demands, the environment, and the regulations of the tractor component manufacturers.

Abstract

Nowadays, the demand for workers in the agriculture industry has decreased and there is a need for rising mechanization in the agriculture process. The agriculture process that requires mechanization is cultivating. The rice cultivator has to be as light as possible, so requires a lighter material but is also strong enough. The correlation between the rice transplanter tool and the wheels is closely related to soil conditions. The selection of wheel materials is considered based on the characteristics of the planting area. In addition, another influence variable is the angle of the fin in the rice transplanter wheel. Material of rice transplanter wheel has been established, these are 1023 carbon steel sheet, AISI 1020 steel cold rolled, AISI 316 stainless steel. The angle of the fin was varied, these are 30, 35, and 40, this fin will give an effect on the traction result of rice transplanter wheel movement. The combination of lightweight material and the appropriate fin angle of the rice transplanter wheel has the best traction result. As a result of this research, the suitable material for the rice transplanter wheel was carbon steel and the fin’s angle was 30. This research involved a comparison and analysis of material strength under various fin angles. The evaluation of stress criteria was conducted using design values to determine the most reliable final product design. The paper contributes by illustrating how to represent the final decision on the combination of design and materials, incorporating a cost index assessment.

Abstract

The rising demand for dependable power supply in tropical areas, characterized by frequent grid instability, requires the use of automated transfer switches (ATS) in hybrid photovoltaic (PV)-grid systems. This study assesses the efficacy of an Arduino Mega 2560-based Automated Testing System (ATS) coupled with a 100 Wp polycrystalline photovoltaic panel and a 12 V 100 Ah battery in the tropical climate of Lampung, Indonesia, over a span of 15 consecutive days in January. The process encompasses hardware design, the construction of a control algorithm based on a multi-objective cost function incorporating risk factors, field data gathering, and MATLAB simulation. The findings indicate that the system attains 80% grid independence based on day count and exceeds 95% based on total energy, accompanied with a minimal switching frequency of 0.2 occurrences per day, signifying stable operation devoid of chattering. A significant contribution is the optimization of the shortfall threshold: adjusting the threshold from 0 Wh to –10 Wh decreases grid reliance from three days to one day, enhancing PV utilization from 80% to 93.3% without adding battery capacity. The relationship between irradiance and photovoltaic energy is robust (r = 0.94, R² = 0.88), with an average system efficiency of 10.04%, which is plausible for polycrystalline panels in hot, humid environments, including cable, inverter, and heat losses. The boxplot analysis verifies the absence of overlap between energy balances on photovoltaic days and grid days, hence affirming the reliability of ATS judgments. In conclusion, the suggested ATS featuring an adjustable deficit threshold is an economical and dependable option for telecommunication infrastructure in tropical developing areas.
