Abstract

Distillation is a technique for extracting Atsiri oils from various plants, one notable example being the Serai Wangi plant (Cymbopogon nardus), a type of herb commonly used in medicine, beauty products, and even as an additive to fuel. Atsiri oils from Serai Wangi can be produced through various methods, such as extraction. The advantage of this method is that it does not require high temperatures, thereby preventing the oil from degrading easily. Consequently, this distillation equipment design was developed to assist farming communities in acquiring an efficient distillation machine. The design process began with a literature study related to the design of distillation equipment. It involved calculating the design of the device and testing the functionality of the distillation equipment. The parameters observed were the effective capacity of the device, its performance, and the yield results. The outcome of this Serai Wangi oil distillation equipment design, featuring an evaporation tank, is that the evaporation process, where the burning furnace heats the water in the tank and steam is directed to the condenser through a connecting pipe, operates efficiently and can produce Atsiri oils of high quality and quantity.

Abstract

Turbocharging system efficiency is a comparison between turbocharging efficiency and turbocharger efficiency. This study analyzes the performance of the ABB 140 and TCR 18 turbochargers on two JGS 620 series F111 gas engines for 3000 hours of operation. The analysis will be carried out based on the specific airflow consumption of the JGS 620 series F111 gas engine. The specific air flow consumption is obtained based on calculations, the ABB A140 turbocharger consumes an average of 0.2% more air than the TCR 18 turbocharger. This condition results in a higher output power on engine 2 on average of 2516.84 kW, compared to the output power engine 1 on average of 2402.72 kW. Based on the calculation of the conduction ratio, the average air consumption on engine 2 is less than engine 1 by 0.41%. The turbocharging efficiency value on the turbine engine 2 side is disrupted at 1700 and 2500 hours of operation. This is due to the disturbance on the turbocharger compressor side of the incoming airflow. The efficiency of the turbocharging system on engine 1 has a value of 79.77%, while on engine 2 it is 77.99%.

Abstract

This study aims to improve the learning outcomes of the basic underhand passing technique in volleyball through the play method for students of class VII.6 at SMP Negeri 3 Palembang. The method used is Classroom Action Research (CAR), conducted in two learning cycles that include planning, action implementation, observation, and reflection to evaluate and improve the learning process. The research subjects were all 30 students of class VII.6 with a Minimum Completeness Criterion (KKM) of 75. The results showed a significant improvement, with students achieving the KKM score increasing from 12 students (40%) in the pre-cycle, to 19 students (63.3%) in the first cycle, and 26 students (86.7%) in the second cycle. These findings prove that the play method effectively enhances the underhand passing technique while motivating students to learn more actively and enjoyably. Therefore, the play method is recommended as a learning strategy to improve the learning outcomes of the basic underhand passing technique in volleyball at school.

Abstract

Penelitian ini bertujuan untuk meningkatkan efektivitas produksi memanfaatkan hasil perhitungan nilai OEE (Overall Equipment Effectiveness). OEE adalah salah satu cara untuk mencari dan  memonitor efektivitas proses kerja dari suatu perusahaan.Setiap perusahaan menginginkan tingkat efektif yang tinggi dalam proses produksi yang dilakukannya. Salah satu upaya yang dilakukan guna menganalisa efektivitas proses produksi dalam hal ini adalah proses pada Paper Machine#3 di PT. XYZ. Dengan sistem TPM (Total Productive Maintenance), yaitu melibatkan operator sebagai pemeran utama untuk melakukan perawatan mesin, penelitian ini dimulai dengan mengidentifikasi kerugian peralatan (Equipment Losses) dan mengukur pencapaian nilai OEE satu lini produksi. Dari periode penelitian yang dilakukan pada Paper Machine#3 (Desember 2016 – July 2018) didapatkan nilai Availability 81,6%, nilai Performance 87,8%, Rate of Quality 92,65% dan nilai OEE 66,85%. Nilai ini masih dibawah nilai OEE standar yaitu  84%. Rata-rata losses terbesar pada Paper Machine#3 terdapat pada Equipment Failure yaitu 44,6%, Set-up & Adjust yaitu 19.05%, Reduce Speed Loss yaitu 12,5%  dan Rewinder Broke Loss yaitu 10,6%. Untuk meningkatkan nilai OEE ke nilai standar perlu diambil tindakan seperti membina kerjasama antar lini produksi dan manajemen agar terbentuk tim kerja yang solid. Perlunya dilakukan pelatihan guna meningkatkan kemampuan tim  maintenance dalam bertindak cepat dan tepat

Abstract

Renewable energy is a sustainable and inexhaustible energy source that can be obtained from water, wind, ocean waves, and solar radiation. Among them, solar energy is an abundant and underutilized resource. This study aims to investigate the heat transfer process from the evaporator pipe to the heated water and to analyze the performance of a horizontal-axis spiral-type solar collector. The results show that the collector effectively absorbs solar energy even under cloudy or rainy conditions, with the highest energy absorption of 35,700 J recorded between 12:00–13:00 WIB. Under cloudy weather, the maximum energy absorbed was 31,500 J between 15:00–17:00 WIB, while under hot conditions, the same energy value (31,500 J) was achieved between 11:00–17:00 WIB. This indicates that solar energy absorption largely depends on the temperature difference (?T) between the collector’s inlet and outlet water temperatures.
