Abstract

In the industry, savings in water use are needed, so that the output water from the condenser will be recirculated for reuse so that it does not need new water. The output of the condenser, which is hot water with a temperature of 45 °C, needs to be conditioned to a normal temperature. So they designed a cooling tower to reduce the temperature of the hot water through direct contact with the air. Filling material is a component that is very influential on the performance of the cooling tower because, in this material, there is direct contact between hot water and dry water in opposite directions. The purpose of this study was to determine the height of the PVC plate filling material that has adequate effectiveness so that the hot water in the cooling process runs optimally. In this study, several tests were carried out that showed the performance of the cooling tower, including range, approach, cooling effectiveness, cooling capacity, and the rate of evaporation of water into the air. So from this research, it was found that the optimal height of fill material is 20 cm, which has the highest relative humidity (RH) of the outgoing air, which is 87.2%, and the lowest exit air temperature of 29.3°C

Abstract

Di bidang ektraksi LPG perlu adanya peralatan handal yang dipergunakan di stasiun gas, salah satunya dengan penggunaan Flow Computer Omni 6000 yang berfungsi sebagai kalkulator gas flowrate yang ditransmisikan, serta dapat mengetahui komposisi gas yang ditransmisikan ke konsumen. Penggunaan teknologi Flow Computer dalam memonitor laju aliran pada proses industri menjadi alternatif yang efektif karena mampu memberikan pengukuran yang lebih akurat, cepat, dan terpercaya. Flow Computer dapat menghasilkan pengukuran data yang akurat dan terus menerus, sehingga dapat membantu meningkatkan efisiensi produksi dan mengurangi kerugian produksi. Oleh karena itu, penulis tertarik untuk mengambil judul “Keakurasian sistem monitoring Flow Rate menggunakan Flow Computer OMNI-6000 di PT. Energi Nusantara Perkasa” dan melakukan sistem monitoring laju aliran gas dibutuhkan data-data yang akurat agar memperoleh hasil yang sesuai dengan kondisi lapangan.

Abstract

Indonesia is an agricultural country with a broad forest area with agricultural areas everywhere and evenly distributed. The Cepu Subdistrict area has fairly broad and has not been fully utilized maximally. The main priority faced by consistent water needs to maintain soil fertility. Solution This need is needed a good irrigation system during the dry season. Conventionally the use of diesel water pumps with fuel for agricultural irrigation systems is needed expensive and ineffective. The utilization of solar power for water pumps is one of the alternatives to reliable, efficient, effective, and efficient solutions to keep the irrigation system running well during the dry season. This service has successfully implemented the use of solar panels of 200WP to run a submersible pump with a depth of ± 4 meters infiltration well. This applied technology uses a timer automation system that runs pump performance during the day. For irrigation systems, implement an automation system in water with 2: 1 where 2 hours of watering and 1-hour filling water reservoir. This application can improve the planting results from farmers around Perhutani land. The land that is originally difficult with water will guarantee the water needs during the dry period.
