Abstract

A plastic extrusion machine is a tool that can be used to process plastic waste into plastic pellets which can be reused to produce plastic products. Therefore, learning and applying these tools is useful for reprocessing plastic waste which is currently increasing. However, it is a shame that the tools currently on the market are relatively uneconomical for institutional scale processing, because the majority of tools on the market are intended for industrial scale. The output of this design produces a prototype tool with dimensions of 1005x350x830 mm and a capacity of 376 grams/hour. Maximum total energy consumption is less than 1 kW. The design of this plastic extrusion machine uses a screw conveyor, a 200Watt band heater and has 2 functions in 1 machine. The first function is to extrude chopped PET plastic and the second function is to cut the extrusion product so that the output of this machine is plastic pellets.

Abstract

Perkembangan kendaraan listrik sebagai solusi transportasi ramah lingkungan mendorong inovasi dalam desain kendaraan ringan, termasuk mobil golf yang digunakan di lingkungan terbatas seperti kampus. Penelitian ini bertujuan untuk merancang dan menganalisis chassis mobil golf yang sesuai untuk digunakan di lingkungan Universitas Muhammadiyah Jember. Desain dilakukan dengan tipe ladder frame menggunakan dua jenis material baja karbon rendah, yaitu AISI 1015 dan AISI 1020. Proses desain dan simulasi dilakukan menggunakan software SolidWorks 2018 dengan fokus pada tiga parameter utama: tegangan (stress), perpindahan (displacement), dan faktor keamanan (Factor of Safety/FOS). Desain chassis diuji menggunakan beban statik yang merepresentasikan penumpang dan komponen kendaraan. Hasil simulasi menunjukkan bahwa desain terbaik diperoleh pada material baja AISI 1020, yang menghasilkan nilai tegangan maksimum sebesar 111,924N/mm², displacement maksimum 0,934mm, dan FOS sebesar 3,1. Penelitian ini menunjukkan bahwa pemilihan desain dan material sangat berpengaruh terhadap performa struktural chassis, serta menegaskan bahwa SolidWorks dapat digunakan secara efektif untuk simulasi awal dalam pengembangan kendaraan ringan.

Abstract

Limbah batang tembakau memiliki potensi sebagai bahan baku alternatif untuk produksi bio-oil melalui pirolisis. Pirolisis adalah metode termokimia yang mengubah biomassa menjadi bio-oil, biochar, dan gas pirolitik, dengan suhu yang berbeda memengaruhi karakteristik produk. Namun, kualitas bio-oil yang dihasilkan bergantung pada parameter proses, terutama suhu pirolisis, yang memengaruhi tingkat pH, Total Padatan Terlarut (TDS), dan kadar alkohol. Penelitian ini bertujuan untuk mengevaluasi pengaruh variasi suhu pirolisis terhadap karakteristik bio-oil yang berasal dari limbah batang tembakau guna mengoptimalkan pemanfaatannya sebagai bahan bakar alternatif. Eksperimen dilakukan dengan menggunakan suhu pirolisis 290°C, 390°C, dan 490°C selama 60 menit, kemudian dianalisis sifat bio-oil melalui pengukuran pH, TDS, dan kadar alkohol. Hasil penelitian menunjukkan bahwa peningkatan suhu pirolisis menyebabkan peningkatan keasaman bio-oil, yang membatasi penggunaannya pada mesin konvensional namun membuatnya cocok untuk pembakaran langsung di boiler. Tingkat TDS meningkat hingga suhu 390°C sebelum sedikit menurun pada 490°C, yang mengindikasikan degradasi termal senyawa terlarut pada suhu tinggi. Selain itu, kadar alkohol dalam bio-oil menurun seiring meningkatnya suhu pirolisis karena volatilitas yang lebih besar pada tingkat panas yang tinggi. Penelitian ini memberikan wawasan mengenai karakteristik bio-oil dari pirolisis batang tembakau, yang dapat menjadi referensi dalam mengoptimalkan teknologi konversi biomassa untuk aplikasi energi yang lebih efisien dan berkelanjutan.

Abstract

The engine pump is used to move fluids by converting mechanical energy into fluid energy and pressure, then transporting the fluid through the piping system. The use of pumps to meet clean water needs. The method with the working principle or how the pump flows fluids or provides fluid power, the results of the study show that the pump capacity with a water discharge of 15 L / m, the total head is 4.807 m, and after knowing the curve where there is an increase in pressure at the outlet (discharge pressure) there will be a decrease in the amount of flow and the higher the amount of flow that comes out, the higher the pressure capacity of the fluid. In the demin water transfer pump, it is known that the available NPSH (6.7 meters) is greater than the required NPSH (6.2 meters), so the pump can. So to fill the water reservoir at the Permanent Nursery Service, the pump operates for 8.5 hours per day. Data analysis and discussion can be concluded that the pump capacity with a water discharge of 15 L/m, the total head is 4.807 m, In the demin water transfer pump it is known that the available NPSH (6.7 meters) is greater than the required NPSH (6.2 meters), so the pump can work without experiencing cavitation. So to meet the needs of the water reservoir in the Permanent Nursery Division, the pump operates for 8-5 hours per day.

Abstract

Indonesia is a country that has a tropical climate, so the content of water vapour in the air is very high, therefore many industrial products are damaged due to high humidity, such as products with hygroscopic material characteristics, for example powder products, medicine tablets, sugar, fertilisers or products with other similar applications. The product will experience clumping so that the resulting product quality is not optimal. On the other hand, high air humidity in a controlled room is certainly very detrimental to the continuity of the production process as well as in clean room applications. Effervescent’s production room at PT Marin Liza Farmasi is an example of a clean room with temperature and RH controlled at 23°C and a water vapour content of 3.47 g/kg with RH less than 20%. If the temperature and water vapour content are not met, production cannot be carried out. The room is positively pressurised with 1177 CFM of fresh air. Damper in pre-cooling is a part that is very influential on the performance of desiccant dehumidifier. Pre-cooling dampers with openings of 10% - 100% openings will affect the value of the bypass factor and air contact factor against the evaporator cooling coil on the pre-cooling AHU, this will also affect the amount of water vapor partial pressure which is influenced by the large temperature coming out of the pre-cooling AHU due to the influence of the evaporator coil temperature. Each damper opening will be tried and analyzed to get the best water vapor content out of the dehumidifier without disturbing the performance of other systems. The damper openings selected for the Effervescent production clean room project at PT Marin Liza Farmasi are the 50% and 60% openings that produce the best dehumidifier performance without interfering with the performance of other systems, which at these openings produce a dehumidifier outlet water vapor content of 1.12 g/kg at the 50% opening with a bypass factor in pre-cooling of 12.26% and 1.2 g/kg at the 60% opening with a bypass factor in pre cooling of 12.90%.
