Abstract

Penjadwalan proyek sebagai alat untuk menentukan kapan mulai dan selesainya kegiatan-kegiatan proyek. Penjadwalan pada proyek, secara umum terdiri dari penjadwalan waktu, tenaga kerja, material, peralatan dan anggaran. Teknik yang digunakan para manajer proyek untuk memprioritaskan aktivitas proyek. Metode CPM bisa membantu mereka menemukan tenggat waktu yang penting agar bisa dipastikan tugas tersebut selesai tepat waktu. Hal tersebut dapat diaplikasikan dalam penjadwalan pembangunan sebuah minimarket yang sudah memiliki penjadwalan waktu oleh departemen proyek untuk mengetahui durasi waktu pelaksanaannya. Dengan metode PERT didapatkan tambahan waktu dikarenakan adanya jam kerja tambahan (lembur) dari asumsi perhitungan metode CPM terlebih dahulu. Perhitungan waktu yang diinginkan untuk pembangunan proyek minimarket dikarenakan target dari perusahaan, bahwa pembangunan toko baru harus selesai terlebih dahulu sebelum toko lama ditutup, dimaksudkan untuk mengejar jatuh tempo masa kontrak toko lama berakhir. Durasi waktu normal pembangunan proyek minimarket selama 23 minggu dengan anggaran Rp.742.704.911,-. Setelah percepatan, durasi proyek tersebut menjadi 17 minggu dengan perhitungan anggaran yang bertambah menjadi Rp. 825.124.139,-.

Abstract

This research aims to analyze the influence of profitability, asset structure, sales growth, and interest rates on stock prices with capital structure as an intervening variable. The research object takes companies that are included in the LQ45 index. The sampling method used is purposive sampling. With the established criteria, 16 companies were obtained as the research sample. The variables used are profitability proxied by Return On Equity (ROE), asset structure, sales growth, interest rates proxied by Bank Indonesia Certificates (SBI), capital structure proxied by Debt to Equity Ratio (DER), and stock price. The data analysis technique used is path analysis.Based on the research results, it shows that partially only profitability affects stock prices. Simultaneously, profitability, asset structure, sales growth, and interest rates together affect stock prices by 12.3%, while profitability, asset structure, sales growth, and interest rates simultaneously affect capital structure by 15.6%. Based on path analysis, capital structure weakens the effect of profitability on stock prices, capital structure weakens the effect of asset structure on stock prices, capital structure weakens the effect of sales growth on stock prices, and capital structure weakens the effect of interest rates on stock prices.

Abstract

The fossil fuel crisis in Indonesia, which contributes 85% of the national energy mix, has driven the need to utilize renewable energy sources, one of which is exhaust wind as industrial waste energy that has high speed (5-7 m/s) and good flow continuity. This study developed a vertical Savonius turbine with variations in exhaust-turbine distance (20, 30, 40 cm) and measured wind speed (5.3, 6, 6.4 m/s) to optimize the utilization of this energy. The results showed that the 20 cm configuration produced the best performance with a maximum power of 5.98 watts at a speed of 6.4 m/s and a Coefficient Performance (CP) of 0.16, which is 31% more efficient than a distance of 40 cm, proving the potential of exhaust wind as a renewable energy solution that is applicable in industry with a payback period of less than 3 years and the potential for reducing the load on the electricity network by up to 15%.

Abstract

Warehouse management in large industries and SMEs (Small and Medium Enterprises) in Indonesia is a critical aspect that must be addressed seriously. Most warehouse systems still rely on manual processes, such as checking humidity, temperature, and gas levels in the storage area. This approach is inefficient as it requires significant time and manpower for regular monitoring. Manual operations using human resources have limitations in terms of labor, time efficiency, accuracy, and operational costs, such as employee wages. To address these challenges, this study proposes the development of an automated system based on the ESP32 microcontroller, which serves as a full controller, utilizing the DHT-11 sensor for temperature and humidity measurement, and the MQ-135 sensor for gas detection. Additionally, Python programming is implemented for data visualization, allowing real-time display on a laptop or computer to facilitate warehouse monitoring. The system developed is designed to read, control, and transmit sensor data. It can measure humidity, temperature, and gas concentration (PPM) and control actuators, such as a relay to activate a buzzer or light, according to the algorithm programmed into the ESP32. The results indicate that the system is capable of reading temperature and humidity with a data error rate of 6%, and gas concentration with an error rate of 2%. Additionally, the data transmission and visualization are functioning properly, in real-time

Abstract

This research was conducted at PT. XYZ is engaged in the textile industry. The problem was experienced due to defects in the Rayon Fiber production process. The purpose of the study was to determine the Rayon Fiber production process at PT. XYZ, to determine the factors causing defects using the Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA) methods, and to provide suggestions for improvement to reduce product defects. The results of the observation showed that there were three types of defects, including White Brightness, Yellow Brightness, and Damaged Wrapping. Of the three aspects, the most dominant types of defects were White Brightness, and Damaged Wrapping seen in the production process in December with a percentage of defects of 14.8%. From the Pareto diagram, it is clear that three problems cause defective goods. To reduce the number of faulty goods, the most common issues - namely, damaged wrapping and white brightness defects - must be addressed by fixing the most defective goods using the 80%/20% approach. After obtaining the severity, occurrence, and detection values related to window product defects, the RPN value will be calculated by multiplying the values above (RPN = S x O x D). By doing the repairs, it resulted in improvements marked by a decrease in the RPN value from 1290 to 553 or 42.8%. The root cause of the problem was because the operator did not follow the existing work standards and did not use the navigation system during the production process. From the results of the study, several suggestions for improvement were obtained, namely conducting periodic supervision and providing re-training to operators regarding the importance of working according to SOP.
