Studi Kuat Tekan Beton Geopolimer dengan Menggunakan Rasio Aktivator 2
Get PDFBeton geopolimer merupakan beton dalam produksinya tidak memakai semen biasa (Portland). Dengan memanfaatkan reaksi kimiawi dan tidak dengan hidrasi reaksi sama halnya beton biasa, yang mana macam - macam bahan aktif pada beton geopolimer dengan senyawa yang terdapat dalam bahan sumber dan komponen lainnya haruslah sesuai sehingga dapat terjadi reaksi kimia. Perawatan dalam pembuatan beton geopolimer ini menggunakan sistem pengovenan dengan suhu rata – rata yakni 60˚C, kemudian didiamkan di tempat terbuka selama 28 hari yang selanjutnya dilanjutkan dengan pengujian tekan. Maka dengan kuat tekan, diperoleh kuat tekan rata – rata fcr beton geopolimer lebih sedikit dari mutu rencana dan lebih sedikit dari kuat tekan rata – rata fcr beton biasa yang telah di uji, rendahnya kuat tekan tersebut karena dipengaruhi oleh jumlah molaritas dari NaOH dan rasio aktivator

JARINGAN SYARAF TIRUAN PADA PT. PLN (PERSERO) ULP PANAKKUKANG
Get PDFThe increase in electricity demand in Indonesia, triggered by rapid population growth, necessitates efficient planning to ensure all citizens can meet their energy needs. PT. PLN (Persero) ULP Panakkukang responds to this challenge by forecasting electricity load using Artificial Neural Network (ANN) method through the Matlab application. Daily electricity load data from the Pengayoman substation in March, April, May, and June 2023 served as the basis for calculations. The research results indicate that the forecasting process using ANN successfully provides values close to the actual load of PT. PLN (Persero) ULP Panakkukang, with low average errors of 0.022%, 0.03%, and 0.018% for May to July, respectively. These efforts are expected to help optimize electricity capacity in the future, considering the uncertainty in predicting electricity demand precisel

Logistic Supply Chain Management System Modeling Using Blockchain
Get PDFIndonesia's economic growth in the logistics sector is becoming increasingly significant, alongside the rising demand for goods. However, the complexity of logistics supply chain management in Indonesia still faces challenges, including security, human error, and lack of transparency. This research proposes the use of blockchain technology for a logistics supply chain management system, which is capable of storing transaction data in a decentralized and distributed manner. Ganache is used as a local blockchain server, Metamask for transactions, and smart contracts to manage user flows on a web3 dapps-based website. The research procedure includes literature study, design, development, and system testing. The test results indicate that all features and functions of the system operate as expected. The system not only successfully handles high demand and transaction spikes but also demonstrates enhanced data security, improved transparency through real-time tracking, and robust performance under high workloads. Overall, this blockchain-based logistics supply chain management system effectively secures and manages transaction data while enabling data tracking and tracing, thereby increasing transparency and handling high concurrent transactions efficiently
Assessment of wind power plant performance using turbine performance and power curves: a case study of PLTB TOLO I Jeneponto
Get PDFJeneponto Regency in South Sulawesi possesses significant wind potential, making it an ideal location for the development of Wind Power Plants (WPP). However, these WPPs are intermittent due to the inconsistent nature of wind energy, presenting challenges that affect the performance and efficiency of turbines in generating electricity. Therefore, this study aims to evaluate the performance of the SWT-3.6-130 wind turbines at the Tolo 1 WPP in Jeneponto to determine their capability in converting wind energy into electrical energy at specific wind speeds. The evaluation results indicate that the performance of the SWT-3.6-130 wind turbines at the Tolo WPP in February 2022 was not optimal. The maximum output power generated by these turbines approached the maximum capacity of 3.6 MW, with Turbine 06 producing 3.57 MW at a wind speed of 13.07 m/s, Turbine 09 producing 3.57 MW at a wind speed of 12.27 m/s, and Turbine 013 producing 3.58 MW at a wind speed of 12.11 m/s. Although the power generated was close to the maximum capacity, the performance variation among turbines indicates the need for further evaluation to address factors reducing efficiency. Power coefficient analysis shows that Turbine T13 exhibited the best performance, with the fewest instances of power coefficient values not meeting standards. This study provides crucial insights for improving performance and preventing failures at the Tolo WPP in the future
Analisis Kinerja Keuangan Dengan Metode Economic Value Added (Eva) Dan Financial Value Added (Fva): (Studi Kasus pada PT Semen Tonasa)
Get PDFThe company's performance could be assessed through the profit it earned, but profit did not always reflect positive financial performance. This study was motivated by a decrease in profit experienced by one of the largest cement producers in Eastern Indonesia, which was PT Semen Tonasa. The purpose of this study was to measure the financial performance of PT Semen Tonasa from 2018 to 2022 using the Economic Value Added (EVA) and Financial Value Added (FVA) methods. This study used a descriptive quantitative approach. Data collection techniques involved document studies and interviews. The results showed that in 2018, the company recorded negative EVA and FVA values, indicating poor financial performance. This reflected that operational activities during that period were unable to create value for the company. In contrast, from 2019 to 2022, the company obtained positive EVA and FVA values, indicating good financial performance. This reflected that operational activities during this period were able to create value for the company.Keywords: Financial Performance, EVA, FV
