tersebut penting untuk memahami aspek kualitas bahan bakar yang digunakan pada suatu unit pembangkit. Kualitas batubara yang kurang baik akan berpengaruh terhadap nilai heat rate, specific coal consumption dan efisiensi. Oleh karena itu perlu dianalisis bagaimana pengaruh perubahan kualitas batubara terhadap variabelvariabel tersebut. Dengan menggunakan kualitas batubara yang sesuai dan pe…
Potential heat is wasted from AC condenser (Air Conditioner) is currently only a waste of energy that is exposed to the surrounding environment. This waste heat has the potential as an energy source that can be used for the drying process. If seen from the potential heat generated by a condenser that is quite large (greater than 3 times the electric power of the compressor and hot air temperatu…
Composite materials are materials that are currently being developed and their use has been widespread in various industrial and household sectors. Composite is a material formed by combining several materials into one and has new mechanical properties as well. In general, composites are composed of binding materials (matrices) and reinforcing materials which are also called fillers. This resea…
Stainless steel AISI 304 merupakan campuran dari berbagai jenis logam yang memiliki kandungan unsur kromium, nikel, fosfor, mangan, karbon, sulfur, silikon, dan nitrogen. Yang menjadikan stainless steel lebih tangguh dan kuat terhadap karat atau tidak cepat mengalami korosi. Penelitian ini bertujuan untuk mengetahui pengaruh kekuatan logam yang di panaskan dengan terperatur tinggi dan di dingin…
Ginger (Zingiber officinale Rosc) is a type of herb and medicinal plant that has high economic value and has been widely known by the people of Indonesia. Ginger water content at harvest ranges from 85% - 91% wet base. High levels of water cause ginger to be easily damaged if not immediately processed or dried. The purpose of this study was to determine the analysis of variations in air tempera…
Teknologi elektronika dapat diterapkan dalam setiap bidang kehidupan sehari hari, contohnya dalam budidaya jamur merang, untuk mendapatkan hasil panen yang optimal dibutuhkan alat untuk monitoring kestabilan suhu dan kelembaban, yang pada prinsipnya suhu normal yang di butuhkan adalah 30℃sampai 32℃ dan kelembaban udara 83 – 85 % di dalam kumbung. Diperlukan suatu alat yang da…
Drying is one way of post-harvest handling to extend the shelf life, especially of agricultural crops. In general, post-harvest drying is only done naturally by drying using heat from solar energy or commonly called conventional drying. In the research on the grain drying process using a fluidized bed drying method in which the drying device was modified by the addition of heat exchanger pipes.…
In the industrial world, heat exchangers have an important role in helping the production process, especially in PT. Amman Mineral Nusa Tenggara. This is because in operation the heat exchange device serves to cool the lubricant on the bearings in the Ball Mill. Heat exchangers (shell and tube type) greatly affect the overall success of the series of processes, because the failure of operations…
The need for energy consumption nowadays becomes very important things, especially the need for electrical energy. Technology to convert heat into electricity directly can be conducted using thermoelectric generators. Thermoelectric generator can convert waste heat to be DC electric. Thermoelectric generator is one of the green technologies needed as an alternative energy. This research uses mo…
Proses perpindahan kalor pada dunia industri pertambangan pada saat ini, merupakan proses kunci kerja dalam suatu mesin, karena semua mesin bekerja dalam temperatur yang cukup tinggi. Salah satu alat penukar kalor (Heat Exchanger), yang digunakan untuk menukar kalor antara fluida kerja yang memiliki perbedaan temperatur. Oleh karena itulah penggunaan heat exchanger perlu diperhatikan perform…
