Abstract

This study aims to solve problems experienced at the Six Store Probolinggo Store where data recording and investigation of sales and purchase transactions still use manual goods receipts. When checking the size or stock of goods for each product when purchasing at offline user sales, the user still has to wait to find out whether stock is still there or not and the high error rate that occurs. The Six Store store needs a way to solve the problems that occur, so the researchers created a system design using the System Development Life Cycle (SDLC) method. This method was chosen because SDLC can measure and improve the sales process more effectively, minimize operational costs and increase revenue throughout the day. While programmers use VB 6.0-based applications and Ms. Access. It can be concluded if there is progress produced by the news system. This proves that regular financial bookkeeping can affect the results of the sale itself. This News System is able to obtain sales reports per note, per item variant, per item and inventory reports in such a short time according to user needs. The results of the application of the Information System show an increase in turnover of 75% every year at the Six Store Probolinggo Store

Abstract

Stroke is a disease that can be suffered by anyone and its handling is not easy. Stroke sufferers need to undergo a therapeutic process so that the function of the limbs can be moved again, such as the feet, hands, and fingers. Based on this, a stroke therapy robot hand was built as a tool to carry out therapy for stroke sufferers. The stroke therapy robot hand consists of two parts, the gloves for the therapist and the hand frame for the sufferers. This tool uses Arduino Nano as a microcontroller base. This tool works by reading the value from the potentiometer in the therapist's hand, then the information is transmitted to the stroke therapy robot's hand via a wireless communication line using the nRF24L01 module which is then run using the Master-slave method. This data will drive five servo motors that are used to move the patient's fingers. From the test results show that the tool can work by calculating the movement of the finger that has moved successfully 98 out of 100 trials. This means that the success percentage of this tool is 98% with an error of 2%.

Abstract

Abstract The current increase in greenhouse gas emissions is a serious concern of various parties both from the community and the government. and one of the biggest contributors is from the transportation side, especially conventional land transportation made from fossil fuels. To deal with this situation, one solution is to switch to using electric vehicles. The Indonesian government itself is fully committed to reducing greenhouse gas emissions, one of which is by issuing Perpres No. 55 of 2019 concerning the development of battery-based electric vehicles. However, this effort is still not enough to attract consumers. This is very reasonable because of the lack of supporting facilities for the electric vehicle itself. one of them is the electric vehicle battery charging station (SPKLU). So that the need to increase the number of electric vehicle charging stations in order to attract consumer interest, with the increasing number of SPKLU will certainly increase the sense of security and comfort for electric vehicle users. Therefore, the purpose of this study is to determine the ideal location of public electric vehicle charging stations (SPKLU), especially in the East Java region and the application is carried out in the city of Probolinggo. The analysis method used in this research is factor analysis to determine the factors that influence consumers in choosing an electric vehicle charging station, then mapping the optimal alternative travel path in the East Java region using the Dynamic Programming method with the Backward Reqursive Equation procedure, then weighting each criterion using the Analytical Hierarchy Process method, and then determining the priority of the ideal SPKLU location using the Composite Performance Index method. The results of the calculation of this study obtained the ideal SPKLU location with the application in the Probolinggo city area, namely at Sukabumi Gas Station as the first priority in placing the location of the public electric vehicle charging station.

Abstract

This text discusses the importance of the electricity network in daily life, highlighting its uses in various activities such as lighting, cooking, and irrigation. It emphasizes the need to follow the standards of PUIL in installing the electricity network, particularly when operating water pumping equipment. The feasibility of the electrical network is crucial, with voltage drop being a major concern. Factors that can affect voltage drop include length, cross-sectional area, material type, load, and current. The research conducted utilizes quantitative research methods to collect and analyze data on the feasibility of the electrical network. The data, collected multiple times under different conditions, is analyzed to determine the percentage of voltage drop, with PUIL guidelines stating it should not exceed 5%. The study also compares measurements and calculations, revealing an average voltage drop percentage of 7.1% and an average voltage value of 15.7V, calculated from an initial voltage of 220V. The study concludes that the results are not feasible due to the high voltage drop percentage and a slight difference between measurements and calculations. Keywords: Feasibility, Network, Voltage, drop, Electricity.

Abstract

This research examines the performance of implementing Model Predictive Control (MPC) in the energy management system of fuel cell – battery hybrid electric vehicles. Three parameter variations were carried out on the MPC controller, namely variations in the horizon value, objective function, and weighting in the objective function. In testing variations in the horizon value of the designed MPC controller, it shows that the higher the horizon value used, the SOC and the final SOC are faster and closer to the optimal SOC determined by compensating for higher hydrogen consumption. Testing of objective function variations shows that the objective function implemented on the MPC controller influences the system response characteristics. It was found in objective function testing that optimal use of fuel cell power produces fuel cell power output with a working efficiency range of 57% - 60% when compared to other objective functions that work in the efficiency range of 49.2% - 57%. Finally, in testing variations in weighting values, it was found that the higher the weighting of an expression in the objective function, the more the optimizer will penalize the expression so that the solver will minimize the expression in the optimization process. Therefore, the MPC controller parameter values ​​need to be paid attention to so that the response characteristics are in accordance with the design. which are desired. It should be noted that this research does not use a speed prediction model so it is assumed that the speed is known without any uncertainty.

Abstract

This paper presents a novel full-wave rectifier to reduce an output ripple of DC wave. Several filter variations have been applied, but the filter output produces a ripple wave output. Therefore, variations of IC 7812, 7815, 7818 and 7824 are proposed to reduce the ripple wave output. The full wave rectifier circuit is designed to regulate the diode output voltage, output current, VRMS and DC motor rotation. The results of applying the IC show that the output ripple can be reduced based on the voltage variation settings on each IC. The greater the variation in IC output voltage, the greater the output voltage, current, VRMS and motor rotation. Meanwhile, the ripple output shows variations in values of 0.252, 0.023, 0.025 and 0.023. The input voltage does not affect the full wave rectifier circuit even though the diode output voltage, current, rpm, VRMS and output ripple vary.

Abstract

Kanker serviks adalah masalah serius dalam kesehatan wanita secara global, dengan tingkat insiden dan kematian yang tinggi. Deteksi dini sangat penting karena perkembangannya yang lambat dan seringkali tanpa gejala pada tahap awal. Salah satu metode yang digunakan untuk mendeteksi kanker serviks adalah klasifikasi melalui pendekatan data mining. Penelitian ini bertujuan untuk menerapkan algoritma K-Nearest Neighbor (K-NN) dan Regresi Logistik dalam klasifikasi deteksi dini kanker serviks, dengan menggunakan teknik pengujian percentage spilt dan k-fold cross validation. Tujuannya adalah untuk membandingkan dan menentukan metode klasifikasi kanker serviks yang paling tepat. Evaluasi dilakukan dengan menggunakan parameter presisi, recall, dan akurasi. Hasil penelitian menunjukkan bahwa hasil pengujian menggunakan validasi silang k-fold mampu bekerja lebih baik daripada persentase spilt. Berdasarkan kinerja algoritma, Regresi Logistik dalam penggunaannya dapat bekerja dengan baik dibandingkan dengan K-NN, dengan nilai presisi, recall dan akurasi masing-masing sebesar 83%, 82,5% dan 96%. Dengan demikian, dapat disimpulkan bahwa Regresi Logistik dengan teknik k-fold cross validation testing lebih efektif dalam mengklasifikasikan kanker serviks.

Abstract

Water is a fundamental human necessity, essential for daily activities such as drinking and cooking. However, access to water can be problematic, especially in areas where water sources are limited or groundwater is far from residential areas. Although various water pumps are now readily available, the challenge often lies in the availability of power sources. Fortunately, in tropical regions, sunlight is freely available year-round. To generate electricity, sunlight must first be converted through an energy conversion process before it can be used to power devices such as water pumps. Therefore, it is necessary to calculate the clean water needs for Tauno Village in Oba Tengah District, Tidore Kepulauan City, which has a population of 516 people. The daily water requirement per person is 60 liters, resulting in a total village water demand of 32,506.85 liters. The total water requirement for all public facilities is 90,037.385 liters. Consequently, a 7,500 W pump with a flow rate of 400,000 liters per day and a head of 10 meters is selected to meet the clean water needs of Tauno Village. To supply power to the pump, 16 photovoltaic panels, each with a capacity of 1,200 Wp, are required
