PENGOPERASIAN SISTEM TENAGA LISTRIK DENGAN PENEMPATAN SLACK BUS DI TIGA GARDU BERBEDA PADA SISTEM KELISTRIKAN SULSELBAR 56 BUS
Get PDFKontinuitas energi listrik tidak terlepas dari keandalan gardu induk. Slack bus digunakan untuk mengalihkan fungsi dari gardu induk yang satu ke gardu induk yang lain jika terjadi gangguan. Slack Bus dipersiapkan untuk memenuhi perbedaan antara beban yang terjadi dengan daya pembangkitan yang disebabkan oleh losses pada jaringan. Pada penelitian ini, dilakukan simulasi pengoperasian sistem tenaga listrik dengan penempatan slack bus pada tiga gardu yang berbeda, yaitu pada bus-1 (Bakaru), bus-31 (Punagaya), dan bus-37 (Sengkang). Pada sistem kelistrikan SULSELBAR 56 bus tahun 2022, simulasi dilakukan dengan menggunakan software MATLAB 2013a. Hasil simulasi total losses terkecil terjadi saat Bus Sengkang dipilih menjadi slack bus dengan total losses sebesar 123.11 MW dan 499.72 MVAr
Monitoring Kinerja Jaringan Kampus 2 Politeknik Negeri Ujung Pandang Menggunakan Aplikasi Solarwinds
Get PDFThe internet network on campus 2 of the Ujung Pandang State Polytechnic (PNUP) often experiences interference with the internet network so that it becomes a complaint from students, lecturers and staff on campus. the network on campus is often down and it is difficult to access internet services to access the internet. So this study aims to measure the parameters of the internet network on campus using the solarwinds application. to analyze the results of monitoring network performance based on the parameters measured. To be able to determine the performance of the campus network 2 PNUP, it is necessary to analyze it by measuring the parameters of network latency, packet loss, throughput and bandwidth usage. Based on the measurement results on holidays in all buildings, the network latency and packet loss results were in very good condition, as well as the throughput and bandwidth were in good condition. By obtaining the overall condition is good. Whereas on the active day of lectures in all buildings, the results showed that network latency was not good and packet loss was in good condition, although there was often an increase in packet loss at certain hours of 100% but it returned to stability, and throughput and bandwidth were in poor condition. By obtaining the overall condition that is not good
Analisis Sistem Security Information and Event Management (SIEM) Aplikasi Wazuh pada Dinas Komunikasi Informatika Statistik dan Persandian Sulawesi Selatan
Get PDFThe South Sulawesi Communication Informatics Statistics and Standardization Office is an implementer of government affairs that assists in carrying out government affairs in the fields of communication, informatics, statistics, and signage. Currently, agencies are utilizing technological developments to maximize their performance, such as the use of web servers to provide information and provide services. But of course this can cause problems such as data theft. Because of the many threats that can attack at any time. Therefore, an application is needed that can prevent this from happening. In order to overcome this, a monitoring system is implemented using the Wazuh application which is an application of SIEM. to find out how this application works in the event of an attack, testing will be carried out using 2 types of attacks, namely Distributed Denial of Service (DDoS) Slowloris and Brute Force. In this test, data will be taken in the form of application responses, namely the response time of the Wazuh application and the classification of the Wazuh application level against DDoS and Brute Force attacks which will be displayed on the Wazuh application Dashboard. Based on the test results, the wazuh application successfully detects DDoS Slowloris and Brute force attacks and can classify these two attacks at levels 3 to 10
The quality of liquid organic fertilizer made from moringa leaf stems as influenced by the concentration of microbes and the duration of fermentation
Get PDFLiquid organic fertilizer from moringa leaf stems was produced through a fermentation process. In this study, moringa leaf stems were utilized by adding banana stems and EM4. The use of moringa leaf stems and banana stems in liquid organic fertilizer was expected to enhance macro-nutrients in the soil, such as nitrogen, phosphorus, and pH. The objective of the research was to determine the optimum conditions for producing liquid organic fertilizer. The experimental variables included adding EM4 starter concentrations of 1%, 3%, and 5% (v/v) to the fermentation substrate and fermenting it for 7, 14, and 21 days. The analysis results indicated that the nitrogen, phosphorus, and pH content of the liquid organic fertilizer met the standards. The optimum conditions were achieved during a 14-day fermentation period with a 5% concentration of EM4, resulting in nitrogen content of 10.06%, phosphorus content of 2.05%, and pH level of 7.5
Rancang Bangun Turbin Angin Sumbu Horizontal 3 Blade Menggunakan PVC
Get PDFWith the increasing need for electrical energy today, resulting in the use of fossil fuels also increasing and in line with its development, the use of fossil fuels will experience shrinkage, therefore other alternative energy is needed to overcome the decreasing fossil fuels. One form of energy that exists in nature is wind. Therefore, wind turbines are starting to be used as alternative energy. The purpose of this design is to determine the performance of a 3-blade horizontal axis wind turbine and to determine the effect of wind speed on turbine rotation, output power and efficiency generated by the wind turbine. The design method is to design a horizontal axis wind turbine using 3 blades of PVC material with a diameter of 182 cm. The results of the wind turbine design show the theoretical data at the highest wind speed of 7.3 m/s with 606.92 watts of wind power generated. In these conditions it can be seen that the wind speed and blade diameter greatly affect the output power of the design results
RANCANG BANGUN ALAT UJI PERKOLASI TANAH BERBASIS ARDUINO
Get PDFWater absorption testing through soil percolation test is mostly handled manually. During the testing process, it still requires many people to supervise it, and the reading error rate is still high. Therefore, a measuring instrument that works automatically is needed that can more specifically read the rate of water absorption into the soil accurately. In this final project, the tool is made using Arduino Mega, HC-SR04 ultrasonic sensor, 128x64 LCD, buzzer, NEO6MV2 GPS Module, RTC (Real Time Clock), push button, and Lithium-Ion Battery. The result of this final project is a soil permeability measuring instrument that can accurately measure the rate of water infiltration. Based on the results of design, testing and analysis of the design results, a soil permeability measuring instrument is obtained that can properly measure the rate of water infiltratio
Simulasi Trajectory Robot Asisten Medis berbasis Odometry dengan Matlab SIMULINK
Get PDFTeknologi robotika semakin berkembang dan diterapkan diberbagai bidang seperti pendidikan, industri, rumah tangga, kesehatan, dan lain-lain. Saat ini dunia dilanda wabah Corona Virus Disease (COVID-19) sebuah penyakit menular dengan gejala umum infeksi seperti flu, demam dan sesak napas. Berdasarkan data World Health Organization, ‎(2020), virus ini sudah menyebar dan melanda banyak negara di dunia dan mempengaruhi berbagai aspek kehidupan. Salah satunya pada sektor pelayanan kesehatan. Dimana untuk mencegah penularan virus ini harus meminimalisir kontak fisik pada orang yang terjangkit virus ini (Baloch et al., 2020). Untuk itu diperlukan sebuah solusi yang dapat meminimalisir terjadinya kontak fisik antara tenaga medis dengan pasien. Robot mobile adalah salah satu teknologi robotika yang dapat memberikan solusi untuk mengatasi masalah tersebut. Pada penelitian ini dirancang pemodelan pergerakan dari robot asisten medis berbasis prinsip odometry. Simulasi dilakukan dengan Matlab Simulink. Dari hasil simulasi dapat dilihat bahwa kombinasi nilai Kp=10, Kd=2 dapat memberikan respon output yang lebih baik karena selisih yang kecil (-/+ 10 rad) ini menunjukkan jika nilai Kp diperbesar dan nilai Kd diperkecil, maka akan memperbaiki respon output sehingga robot dapat bergerak sesuai dengan trajectory yang diinginka
