Abstract

The forecast of electricity consumption is a prediction of the use of electricity for the future by referring to the use of electricity in past data. Estimates of electricity consumption needs are intended to estimate how much electricity consumption is used by customers and must be provided by PT PLN (PERSERO) ULP SIBUHUAN as a provider of electrical energy services. Population growth occurs along with the development of an area, so it affects the demand for electricity and the need for electricity consumption. Load mapping must be done to maintain the continuity and distribution of electrical energy to customers. One way to preserve the continuity of service is to estimate electric power consumption using several forecasting methods. One of the methods that can be used is to combine several load forecasting methods called the combined method. The combined method is a model that incorporates various estimation methods, including econometrics, analytics, and trends, using historical customer data originating from BPS (Central Statistics Agency) Padang Lawas Regency and PT. PLN (PERSERO) ULP SIBUHUAN. The estimated load between 2021 and 2025 is 625,070,452 kWh, with an increase in electricity consumption of 20.7%, household expenses increasing by 1.8%, and business sector expenses by 1.35%. The method used is to calculate manually using Microsoft Excel to obtain forecasting values for population growth; increasing electricity consumption is very important for planning electric power generation, development, and planning of electric power distribution and mapping of loads on customers.

Abstract

Kimpul (Xanthosoma sagittifolium) is one of the local products that produce non-rice carbohydrates that have the potential to be developed. The potential of kimpul tubers can be developed by utilizing it into various types of processed products to provide value. The kimpul tubers can be processed into kimpul chips, kimpul sticks, or other preparations. Meanwhile, kimpul flour can be processed into various products, including wet noodles, biscuits, cookies, pastries, or other processed forms. From the various diversification of processed products, it has the potential to be developed into food industry products. For this reason, it is necessary to analyze the value of the various preparations in terms of product performance and required production costs. The purpose of this study was to determine the performance of various kimpul preparations with various criteria, analyze the production costs of various kimpul preparations, conduct value analysis of various kimpul preparations based on performance and cost analysis, and provide recommendations for the type of product that is able to provide the best value. Product performance is based on the parameters of organoleptic properties, product attractiveness, product benefits, and product purchase decisions. The value of the product is analyzed based on the benefits of the product and the costs required to realize these benefits. The results of product value analysis show that products that have high benefits, but only require relatively low costs provide high product values. Alternative products that are recommended to be produced are kimpul chips, kimpul sticks, and kimpul cookies.

Abstract

In this paper, the performance of the DC-DC converter is assisted by MPPT control in a comparison between Perturb & Observe (P&O) and Incremental Conductance (IC) using the Simulink Support Package for Arduino Hardware. In photovoltaic systems, the maximum power point tracking needs to be powered by PV panels. A microcontroller controls the power converter. Before it is designed, the system is first modeled and simulated using MATLAB/Simulink. The control software implements a pulse-width modulation signal generator embedded in the Arduino microcontroller. The many stages of design for these controllers are discussed, along with simulation and experimentation. The system is tested, and the irradiance varies from 500 w/m2 to 1000 w/m2. The results of this simulation and experiment show that the plan with MPPT and a P&O controller has a higher efficiency of PV power production.

Abstract

The transformer is one of the essential parts of an electric power system. The distribution transformer is a part of the electric power system which plays a vital role in providing electrical energy services to customers. The increasing population and the development of the times make the need for continuous electrical energy. One of the causes of insulation failure in transformers is overheating in the central part. The transformer requires a cooling system to control the heat energy generated. Transformer oil is an insulating and cooling medium for the central part of the transformer. At the time of operation, some disturbances cause the emergence of gases such as carbon dioxide, ethane, and ethylene. The purpose of this study was to design a device for detecting levels of carbon dioxide (CO2), ethane (C2H6), and ethylene (C2H4) dissolved in transformer oil by displaying the ppm (parts per million) value for each gas. Atmega328 microcontroller is used for system control and as a data processor. The data is in the form of a voltage that the ADC microcontroller feature will change. This information is used to calculate the ppm value for each gas. The concentration of this gas will be displayed on the LCD control panel. From the results of this study, the DS18B20 sensor used has an error of 0.00315%, the MG-811 sensor has an error of 10,022, the MQ-6 sensor has an error of 7,918, and the MQ-2 sensor has an error of 9,356. This is indicated by the LCD output, which receives data automatically.

Abstract

Eggplant (Solanum Melongena L) is a type of seasonal vegetable. Eggplants vary in shape and color from white to green to purple. Facts prove that eggplant plants face several threats to their survival and growth, including disease disturbances such as leaf beetles, fruit rot, mealybugs, etc. One way to treat and monitor eggplant plants is to install a camera to capture accurate and fast image data. The image captured by the camera will be digitally processed, which can be used by deep learning methods on object recognition and evaluation system in eggplant plants. Digital image processing can present the color accuracy of leaves, and fruit stems in eggplant plants for solutions and innovations. Digital image processing is the study of image processing techniques. Processed images are still images or images captured with a model camera. In this study, the images taken were of colored leaves attacked by eggplant rot and brown stem rot. The color model used in this study to transform images to color uses the red-green-blue color function. This study uses the YOLOv4 algorithm implemented on a mobile computing device such as Raspberry Pi 4 to select images of eggplant plants captured by a camera. The image data that has been processed will produce results in plant disease diagnoses based on the image captured by the camera. The results will be announced immediately or announced on the Telegram application. We can then detect diseases in eggplant plants and provide immediate preventative measures for diseased plants to maximize yield.

Abstract

Modern technology is developing quite fast. Manufacturing, consumer electronics, and traffic management are just a few everyday tasks made more accessible by various technologies. Regular traffic signals work according to a set time or hour according to one road condition. Therefore, it is essential to time traffic signals at intersections so drivers must wait for the shortest time. In this study, we explore the feasibility of modeling a control system using the fuzzy Mamdani algorithm so that the timing of traffic lights at highway intersections can be adjusted in real-time. Each element, such as the number of cars, motorbikes, and road width, plays a role in determining whether or not a traffic light is activated. It is possible to get a red light that changes adaptively in response to road conditions by conducting tests with varying parameter settings. Based on the results of testing the system as a whole, it can be determined that traffic lights can prioritize the long green density first among the four lanes if the number of cars in one of the lanes is more, and those in the fewer lanes will take precedence over the more congested roads. That system testing is booming, according to design. Battery-free toy vehicles were deployed on each track for testing. The sensor will recognize the car as an object and interpret the data sent and received by the Arduino Mega processing system. The system will then analyze the density condition and display it on the LCD and sensor data, the length of the green traffic light, and the density condition.

Abstract

The existence of street vendors tends to dominate public spaces, which is physically considered to affect the physical quality. Tengku Amir Hamzah Square (TAHS) in Stabat is a famous local public space. Its strategic location triggers the growth of street vendors who provide attractions for visitors. Initially, TAHS was designed not to provide a space for street vendors, and the local regulation said that the presence of street vendors was prohibited. The existence of street vendors in TAHS who occupy this public space has emerged with pros and cons. This phenomenon became the reason for this study to be conducted, specifically to uncover the pattern of temporary space and space-forming elements created by street vendors and their relationship with the public's interest in visiting TAHS. The mixed-method research approach is used in this study to disclose and analyze data descriptively. Mapping and observation were carried out to obtain quantitative data, including layout, the number of street vendors, merchandise types, and distribution patternshod of displaying. The elements that form public spaces implemented by street vendors are obtained through observations and photo-trekking, and 58 respondents were involved in the interviews. Findings indicate that the strategic location and fluent permeability to and from TAHS have made this potential street vendor attraction popular among the locals. The activity created in this area acts as a generator of movement, especially at night, attracting people to come and walk through the existing street vendor outlets, contributing to urban livability.

Abstract

Fish is a food in great demand at home and abroad, and apart from its delicious taste, fish is also prevalent because of its health benefits. High protein content and lower fat content compared to other animal protein sources. However, the quality of fish is effortless to decline and spoil. One of the efforts to preserve processed fish so that it can be stored for a more extended period is using preservation. The purpose of preserving fish is to keep fish as long as possible by eliminating the causes of spoilage. There are various types of fish preservation, one of which is drying. Fish drying is a process of reducing the water content in fish to inhibit spoilage. Several factors affect the drying fish’s operation: temperature and airflow velocity. Temperatures that are too large can cause case hardening where the outside of the fish is dry, but the inside is still wet. Then the temperature chosen in this study was 50°C and 60°C with consideration of nutritional standards for dried fish and airflow velocity of 1.5 - 2 m/s. According to SNI 2732.3: 2009, the maximum water content in dried fish is 40%. This system is supported by a type k thermocouple temperature sensor, load cell sensor, tubular heater, fan, solid state relay, keypad, I2C LCD, and Arduino mega. Two input variables must be controlled in a fish dryer: temperature and weight. At variable temperatures, the input is a type k thermocouple sensor. The output is an SSR that holds the tube heater so that the temperature of the fish dryer matches the setpoint temperature. The fuzzy logic method controls the temperature when drying fish does not exceed the set point temperature.
