Abstract

Sepeda motor merupakan salah satu alat transportasi yang banyak digunakan oleh penduduk Indonesia. Alasannya sepeda motor lebih praktis dan lebih hemat jika dibandingkan angkutan umum. Dalam beberapa tahun terakhir, energi merupakan salah satu permasalahan yang krusial, dikarenakan nilai produksi minyak bumi berbanding terbalik dengan nilai konsumsinya serta semakin menipisnya deposit sumber cadangan minyak dunia. Tujuan penelitian ini untuk mempelajari tentang pemanfaatan hydrocarbon pada bahan bakar dengan cara dipecah menjadi atom hydrogen (H2) dan carbon (C) menggunakan pipa katalisator yang dipanaskan terhadap unjuk kerja motor bensin SupraX 125. Bahan bakar dipanaskan menggunakan katalis yang memiliki panjang 20 cm dengan pengaruh diameter annulus konsentris pada HCS (Hydrocarbon Cracking System). Hasil dari penelitian menyebutkan metode HCS (Hydrocarbon Cracking System) sangat efektif digunakan sebagai power suplemen untuk menghemat bahan bakar. Selisih nilai SFCe bahan bakar premium terhadap variasi perlakuan HCS sebesar 0.5 kg/HP.Jam. Pemasangan HCS mempengaruhi terjadinya penguraian atom Hydrogen (H) yang membuat pembakaran lebih cepat. Hasil uji emisi secara keseluruhan menunjukkan peningkatan kualitas pada emisi gas buang. Prosentase CO menurun yang diakibatkan peningkatan O2 dalam pembakaran yang sesuai dengan penurunan kadar HC. CO berkurang pada ruang annulus konsentris yang semakin besar. Ini menunjukkan adanya masalah pada mesin yang dikarenakan adanya ketidaktepatan waktu penyalaan bahan bakar. Kata kunci : katalis, annulus konsentris, dan HCS (Hydrocarbon Cracking System).

Abstract

Efficiency and effectiveness are indispensable things in the production process. Accurate use of existing resources and the shorter cycle time of production are of particular concern to optimize the production process. This research aims to implement automation to a conventional blow molding. An advanced attempt was carried out to use the Internet of Things (IoT) to increase its efficiency while maintaining the quality of the products. The use of the nodeMCU microcontroller and the blynk application allows the operator to operate the machine without having to come into or having direct contact with the machine. The performance of automation and IoT were tested by examining the products using Taguchi design using quality criteria of nominal the best. The efficiency of the system was also considered by comparing the cycle production time. S/N ratio of Taguchi analysis showed that the optimum volume of the bottle would be achieved when applying the temperature, injection time, and holding time of 190 oC, 14 minutes, and 5 minutes respectively. The error or deviation is only 0.41%. The application of the IoT system takes 34.45 seconds for a cycle time production, which is 3.76 seconds faster than a conventional system.

Abstract

Since 2006 Indonesia has become the world's largest producer of Crude Palm Oil. Also, palm oil is a strategic commodity both as food (cooking oil). The need for self-cooking oil every day is increasing, causing businessmen who plunge not only to have significant capital but many from SMEs and MSMEs who start a cooking industry in the home industry. In the home industry for cooking oil packaging, the manual method is still used, which is to drain oil from the reservoir to the package through a pipe that is given a tap to open and close. This study studied PLC-based cooking oil filling machines using a timer and timer method to improve efficiency, charging speed, errors as small as possible and to increase production capacity. The test results showed that the cooking oil filling process using the measuring method had an average of 159,478 (g / dt) with an average oil yield of 689.2 grams with an error rate of 0.23%. While the timer method has an average filling speed of 164.336 (g / dt) with an average oil yield of 692.08 grams with an error of 0.336%. The timer method has a faster-charging speed compared to the measuring process, but for the error rate, the purpose is better than the timer method. This is due to the way of using the rotary encoder sensor when charging, so the time required for charging is a little long but with a small error rate. While the timer method uses a timer sensor that is on the PLC to make charging directly into the bottle but has a more significant error compared to using the measuring process. For engine capacity, it is better to use a timer method that produces 5145 liters/day while the gauge method is only 4984 liters/day. whereas for efficiency, it is better the process of measuring is 99.68%, and the timer method is 99.27% Keywords: Timer Method, Measuring Method, Cooking Oil Filling Machine and PLC
