Planning for the Construction of a Solar Power Plant in Vaname Shrimp Ponds in Sungai Kuruk III Village, Seruway District, Aceh Tamiang Regency

2024-06-10T15:21:05+07:00

The construction of a Solar Power Plant (PLTS) in the Vaname Shrimp Pond, Sungai Kuruk III Village is an efficient solution in overcoming excessive electricity consumption in vaname shrimp cultivation. With the majority of the population working as fishermen and shrimp farmers, shrimp farming requires significant electricity consumption for lights, water pumps and windmills. PLTS is an efficient and sustainable solution by utilizing abundant solar energy in coastal areas. This research uses 28 solar modules with a capacity of 500 Wp, 23 batteries, an inverter with a power of 3,000 watts, and a Solar Charge Controller (SCC) with a capacity of 350 A. Thus, the implementation of PLTS is expected to reduce dependence on PLN electricity while still increasing and maintaining energy productivity as well as maintaining environmental sustainability in vaname shrimp cultivation.

2024-09-06T21:57:34+07:00

To achieve stable internet communication services, it is necessary to have good internet service quality. The greater the transmission capacity and bandwidth used, the faster information can be accessed from the internet. Quality of Service (QoS) is a measurement method used to determine the capability of an internet network to provide better and planned network services to meet the needs of a service. In analyzing the Design of Fiber Optic Networks for Quality of Service (QoS) improvement between Gandul and Duren Tiga, two factors need to be known, namely the Fiber Optic network and several parameters such as throughput, packet loss, jitter, and delay. In the analysis of the Fiber Optic network, the focus is on reducing losses in the network, while for parameters such as throughput, packet loss, jitter, and delay, observations are conducted using standard telephony and Wireshark applications. The results of the analysis based on the triphone standard show that the quality of throughput speed in the Gandul and Duren Tiga areas is still subpar, especially in terms of throughput. To improve some of these inadequate/poor parameters, several steps are taken, namely by adding/installing a Small Form-Factor Pluggable (SFP). By installing a Small Form-Factor Pluggable (SFP), some of these parameters can be improved, specifically in terms of throughput in the Gandul and Duren Tiga areas.

Requirements Gathering for Building a Hospital Queuing Dashboard and Automatic Voice Dialing

2024-06-10T15:21:53+07:00

This research analyzes how the queuing process currently occurs at Porsea Hospital which still uses a manual system and to analyze how this system can influence the effectiveness of the queuing process between patients and the hospital administration. The focus of this research is to build a tool called the hospital queue dashboard and automatic voice dialing. Data collection was carried out using qualitative methods and through descriptive data analysis using archival research techniques. With archival research, ten journals were studied as references in building the system. The results obtained from the journals studied are that changes are still needed in the system used to overcome the current queues, considering that the tools used in the system are still less efficient in their use for patients and administration. Therefore, researchers will build a system called hospital queue dashboard and automatic voice dialing using components consisting of a 16 x 4 LCD as a dashboard to display queue numbers and patient queue status, an Arduino speaker as a caller for patient queue numbers and using buttons as buttons. the input that the patient will press to receive the desired output. which will be used to overcome queuing problems that occur in hospitals and overcome inefficient queuing processes. It is hoped that this system can be a solution in overcoming the queuing process in hospitals and can increase efficiency and comfort between patients and hospital administration in the queuing process.

20kV Cubicle Maintenance at PT PLN (Persero) APJ Banten Utara Rayon Prima Krakatau

2024-06-13T23:31:20+07:00

The disturbances that often occur in 20kV cubicles are those with low insulation resistance values caused by several factors such as environmental conditions, humidity levels, dust, temperature, water, pressure disturbances and other disturbances. If this disturbance is left unchecked, it can cause short circuits and electric current leaks. Another disturbance that is often experienced by 20kV cubicles is corona, where this disturbance causes a hissing sound in the cubicle and the appearance of rust on the indoor contact parts of the cubicle. If this condition occurs continuously it can cause serious damage to all 20kV cubicle components and cause losses for customers and PT. PLN (Persero). So to anticipate these problems, maintenance is required on 20kV cubicles. PT. PLN (Persero) carries out annual maintenance of 20kV cubicles to increase the insulation resistance value and overcome the problems of hissing and rust caused by corona events. This Industrial Practice assignment discusses the maintenance of 20kV cubicles in accordance with PT's SOP. PLN (Persero). After carrying out maintenance on the 20kV cubicle, the problems that occur can be resolved, such as increasing the insulation resistance value and the disappearance of the hissing sound and rust on the contacts of the 20kV cubicle.

Water Level Classification for Early Flood Detection Using KNN Method

2024-06-25T09:44:42+07:00

Floods occur when water levels exceed normal limits, causing rivers to overflow and inundate low-lying areas. Early warning systems for flood disasters are crucial to mitigate the damage caused, such as loss of life and property. A flood classification system can be developed by utilizing water level data from the Department of Water Resources to predict the likelihood of flooding using the K-Nearest Neighbors (KNN) algorithm. This study aims to determine the flood status classification based on water levels using the KNN method in the Ciliwung River. The research data were obtained from the DKI Jakarta open data site, consisting of 564 samples. The study evaluated K values ranging from 1 to 10. The average accuracy across all K scenarios was 99%, with the best K value being 1, which provided 100% accuracy, sensitivity, and specificity. These results indicate that the KNN method is effective in classifying flood status based on water level data, making it a reliable tool for early warning systems. This system is expected to help reduce the negative impacts of floods by providing accurate and timely information to the public and authorities. This research makes a significant contribution to the development of disaster mitigation technology, particularly in flood risk management in urban areas.

2024-09-06T17:24:54+07:00

Based on data from the national waste information system, total waste in Indonesia in 2022 will be 36.1 million tons per year. Referring to this data, there is still a lack of waste processing and requires quite large costs for waste processing resulting from the increase in population, changes in consumption patterns and people's lifestyles. As a solution, researchers have developed a tool to make 3D printing filament using used bottles as the main material. The tool is equipped with a stepper motor that controls the process of winding plastic bottle tape into 3D printing filament. Regulating the rotation of the stepper motor and controlling the tool as a whole uses an Arduino UNO microcontroller and a potentiometer.

2024-09-08T12:10:34+07:00

This paper proposes a novel control strategy for enhancing power quality through the implementation of an Interval Type-2 Fuzzy Logic Controller (T2FLC) for Shunt Active Power Filters (SAPF). The presented method effectively addresses harmonic distortions introduced by non-linear loads, a common issue in modern electrical systems. Extensive simulations conducted in MATLAB/Simulink demonstrate the T2FLC's ability to regulate the DC bus voltage while significantly reducing Total Harmonic Distortion (THD). The method achieves superior performance compared to both traditional passive and active filtering techniques, reducing THD within the limits specified by IEEE 519-2014 standards. The results confirm the robustness and adaptability of the proposed approach across varying load conditions, establishing it as a reliable and scalable solution for improving power quality in complex electrical networks.
