Abstract

Plant factory is a plant warehouse with a closed planting maintenance system which is expected to overcome the problem of pest attack and disturbance of climatic factors. In this study, an IoT-based light intensity monitoring system has been designed at the Plant Factory, Experimental Garden, Faculty of Agriculture, Udayana University. To monitor the value of the LED light intensity. The hardware used in this study uses 2 microcontrollers, namely arduino nano and ESP 32, using a BH1750 sensor to measure the intensity of light lux and using RTC to calculate the time on the device. All hardware components are assembled in parallel and become an IoT system, which is one way to be able to carry out automatic monitoring and control of lights that can be done anywhere. Monitoring with IoT at the plant factory using the internet which can be accessed through the blynk application. With this technology, it is expected to be able to regenerate farmers in the future to farm using IoT technology, the concept of hoeing and plowing, becoming more modern farming.

Abstract

The wheelbarrow is a tool for transporting material in mining, plantation, and other areas that is pushed by one person with two rear handles and one wheel in the front. However, its use still requires and relies on a large amount of human power. The workers still have to expend energy to push the wheelbarrow which of course will be very heavy if the load is added in the wheelbarrow. Therefore, it is necessary to add an additional driving force to the wheelbarrow that can help the workers so that they can save their energy and also can make work more efficient. This wheelbarrow will use a DC motor as the driver and use Arduino uno with the PWM method as the control system. In addition, the tool will use a Lithium-ion battery so that it is more durable and can be easily recharged. The battery used has a voltage of 24V and a capacity of 9Ah. This semi-automatic wheelbarrow that uses a dc motor can help work faster up to about 32.5% more efficiently than without using a dc motor. In addition to being more efficient in use, wheelbarrows with dc motors also make it easier for users to use these tools compared to wheelbarrow without dc motors.

Abstract

The slow development of New and Renewable Energy such as solar energy in Indonesia are influenced by land acquisition and the high initial investment costs, but lately the cost of solar power plant development prices has been decreasing globally year by year. This research will review the development of PV mini-grid investment costs in Indonesia and this information can be used as a source of information for stakeholders to understand the development of PV mini-grid prices in 2022. The price of the solar power plant construction was obtained through a survey from the e-commerce website. From the survey, 55 data has been obtained related to the price of solar power plant rooftop construction in Indonesia with a capacity scale of 1 KWp to 10 KWp with price range from Rp. 14,000,000 to Rp. 207,000,000. The average initial investment cost for the construction of a PLTS Roof in Indonesia with a capacity of <2 KWp is Rp. 22,954,000, <3 KWp is Rp. 42.838.000, <4 KWp is Rp. 60,716,000, <5 KWp is Rp. 64,473,000, <6 KWp is Rp. 82,986,000, 6 KWp is Rp. 102,380,000, 7 KWp is Rp. 117,580,000, 8 KWp is Rp. 140,980,000, 9 KWp is Rp. 156.580.000, and 10 KWp is Rp. 151,820,000.

Abstract

Indonesia is one of the countries prone to natural disasters, such as soil movements and earthquakes. The people of Indonesia have felt various kinds of impacts caused by the disaster, both in the form of losing their jobs, their homes, and even their beloved family members. However, this impact can certainly be minimized with good disaster management. Therefore, the author focuses on the clustering of earthquake-prone areas in Indonesia using Density-based Spatial Clustering of Application with Noise (DBSCAN), Common Nearest Neighbor Clustering (CNN), and K-Medoids. The results of the clustering show that the soil movement-prone cluster formed from the DBSCAN algorithm is centered on the islands of Java and Bali, as well as along the western part of North Sumatra to Lampung, while the earthquake-prone areas formed from the K-Medoids algorithm are spread over the area traversed by the Pacific Ring of Fire.

Abstract

With the increasing demand for electrical energy, steps are needed to increase the production of electrical energy and one of them is the study of PLTG fuel. The PLTG fuel study aims to analyze the ratio of the generated electric power and fuel costs to the power generated by the PLTG. The benefit of this study is to know how much the ratio of power and fuel costs to the power produced, so that it can be used as a reference to determine which fuel is suitable for use. With a quantitative descriptive analysis method where the qualitative data from the calculation results will be described descriptively so that the advantages, disadvantages and differences of the three fuels can be identified. Through SFC calculations the results of this study show that LNG fuel has the lowest SFC value of 0.13 kg/kWh while for HSD it is 0.33 kg/kWh and MFO is 0.43 kg/kWh. With the same amount of fuel, the power produced by LNG is still higher than the other two fuels, which is 40.48 kWh, followed by HSD, which is 25.77 kWh, and MFO, which is 22.63 kWh. When viewed from an economic perspective, LNG is also the cheapest fuel, with a price of IDR 33,639.02, -, while MFO is slightly cheaper than HSD, which is IDR 194,000.00 and for HSD fuel, which is IDR 223,500.00,-.

Abstract

Solar Power Plant is a power generator that converts sunlight into electricity. Solar Power Plant has a simple concept, namely converting sunlight into electrical energy. These solar cells can produce unlimited energy directly taken from the sun, and do not require fuel, so solar cells are often said to be clean and environmentally friendly. This journal discusses how to design a Solar Power Plant system at PT Bali Cukup Mandiri. The design is in the form of calculating the number of solar panels that can be installed, the capacity obtained, calculating the required capital costs, choosing the appropriate type of Solar Power Plant, the profit and loss if the Solar Power Plant is installed, and a comparison of electricity costs before and after it is installed. The simulation results of Solar Power Plant electrical energy production using the Helioscope and HOMER applications. The calculation results for the Solar Power Plant system for a capacity of 8 kWp require 24 units of 335 Wp solar modules, using a Solar Power Plant installation system of 24 serial units, the capital cost for making Solar Power Plant is around Rp. 114,504,000 electricity generated by the PV system is 13,337 kWh/year and accommodates up to 49% of electrical energy. savings of IDR 16,303,604 in one year after deducting the total electricity bill payments. The total time needed to cover the initial investment in designing a rooftop solar system at PT Bali Cukup Mandiri is 8 years.

Abstract

The number of PLTS installed on factory rooftops is growing. In Indonesia, the Directorate General of New, Renewable Energy estimates a total renewable energy potential of 442 GW, with solar energy holding the greatest potential. The performance of the PLTS system needs to be considered to ensure good performance in generating electricity. This research focuses on the rooftop on-grid PLTS system in a Pharmaceutical Company located in the PT Jakarta Industrial Estate Pulo Gadung area, with a capacity of 463.25 kWp. Electricity generation potential is modeled using PVSyst software for examination of the PLTS system's performance. For the period of one year, from November 2021 through October 2022, the PLTS system's performance characteristics are determined. These include the Yield Factor (Yf), Reference Yield (Yr), Performance Ratio (PR), and Capacity Utilization Factor (CUF). According to the model, the 463.25 kWp on-grid rooftop PLTS system may generate up to 629,550 kWh of power each year. The values of the PLTS system performance parameters are as follows: Yield Factor (Yf) is 1,358.99 kWh/kWp, Reference Yield (Yr) is 1,730.6 kWh/kW, Performance Ratio (PR) is 78.56%, and Capacity Utilization Factor (CUF) is 15.73%. Meanwhile, the actual electricity production for one year is 570,724.82 kWh, with the following performance parameters for the PLTS system: Yield Factor (Yf) is 1,232 kWh/kWp, Reference Yield (Yr) is 1,642.85 kWh/kW, Performance Ratio (PR) is 76.12%, and Capacity Utilization Factor (CUF) is 14.26%. There is a difference between the PVSyst software simulation and the actual results, which are 58,825.18 kWh, 126.98 kWh/kWp, 87.75 kWh/kW, 2.44%, and 1.47% respectively.
