Abstract

Increasing heat and vapor transfer between air and product to be dried is animportant issue in drying of Refuse Derived Fuel (RDF) and agricultural products. Generally, manual mixing is used in order to increase the contact area between air andproduct to be dried. The applications of vibration system on dryer machine can be used todry RDF and agricultural products. Even if the use of dryer machines has been widely usedto dry RDF and agricultural products with avoiding the heat loss needs to be verified. Theobservations shown that the using of vibration system for moving RDF and agriculturalproducts were on the shelf could not be moved optimally. The previous study found that thespring load on dryer machine was too large and most of the surface of RDF and agriculturalproducts were on the shelf could not get hot air flow. That’s why the spring used as pedestalof shelves would be broken fast and on a specific moment RDF and agricultural productsmust be taken out of the drying chamber to be manually moved. To solve the problems andto develop the results of previous study, then it needs to do the study about analysis,simulation and experimental of vibration. In this study, vibration was analyzed to having aninsight on suitable condition of the dryer machine for use in drying RDF and agriculturalproducts. Beside that the study only uses an unbalance mass and it does not use a pistonengine, so spring load would be smaller. The objectives of the study is to perform analysis,simulation and experimental of vibration in order that the RDF and agricultural products areon the each shelf can be dried fast and moved optimally. The study use observation,literature study, analysis, simulation and experimental methods and cashew nuts as thematerial tested on the each shelf. The study results show that the condition of vibrationapproached resonance cause cashew nuts placed on the each shelf could be moved optimally,therefore the surface of RDF and agricultural products were on the shelf could get hot airflow. The final moisture content of vibrated samples was lower than the samples withoutvibration.

The final moisture content of vibrated samples was lower than the samples without vibration.

Abstract

Heat exchanger is an equipment designed to exchange heat between two fluids by applying heat transfer by convection and conduction without mixing the two fluids. heat exchangers are used in the gold mining industry in the gold elution process stage with the type of alat penukar kalor pelat datar(PHE) UFX-42H to reheat the eluate (water) using glycol as the heating fluid. The PHE has a leak on the back base plate. This report aims to analyze the comparison of the effectiveness and LMTD of PHE between specification data and operational data at the time of leakage. The calculation off effectiveness requires the suhue, mass flow rate, and specific heat of the fluid. The results obtained were the effectiveness of the specification data is 0.83 and the mean of operational data is 0.71. The results of LMTD specification data is 23.91 and the mean of operational data is 28.1.

Abstract

Kebutuhan pompa dikalangan industri berperan penting dalam proses produksi, penggunaan yang meluas menyebabkan faktor permasalahan efesiensi, pengeluaran dan maintenance menjadi topik yang akan dipecahkan. Efesiensi yang dihasilkan dari kalangan peneliti sebelumnya mencapai 47%, masih dapat dikembangkan dan biaya pendapatan maupun pengeluaran belum dapat disimpulkan. Penelitian ini, meningkatkan efisiensi penggunaan solar cell pada pompa dan biaya pengeluaran diselidiki. Penerapan metode eksperimen dilakukan pada perancangan solar cell sebagai sumber data intensitas cahaya diselidiki. Melakukan analisis perhitungan daya pompa, daya solar cell, perbandingan dari segi ekonomi penggunaan solar cell dan genset. Data primer dan suplai energi genset menjadi bagian pembanding dalam penerapan metode simulasi desain. Hasil pengujian solar cell pada penelitian ini yang tertinggi pada sudut 35° sebesar 1,93 kWh/m², menunjukan bahwa efisiensi mengalami kenaikan 52.41% dibandingkan dengan peneliti sebelunya efisiensi sebesar 51.61%.

Abstract

Baterai merupakan salah satu komponen terpenting pada kendaraan listrik. Dari beberapa jenis aki yang ada di pasaran saat ini, Indonesia harus bisa mengkolaborasikan antara ketersediaan bahan baku dan teknologi pembuatan dan perakitan baterai tersebut agar jenis baterai yang dikembangkan efektif dan mampu bersaing di pasaran. Penelitian ini dilakukan untuk mensimulasikan baterai Lead Acid, Nickel Metal Hydride (NiMH), dan Lithium-ion (Li-ion). Data yang dihasilkan merupakan hasil kajian literatur dengan menggunakan metode weighted objective dengan membandingkan kriteria yaitu kepadatan energi, emisi baterai, proses manufakturing, ketersediaan bahan baku utama, dan fasilitas daur ulang dari baterai. Data yang diperoleh untuk setiap kriteria digunakan sebagai dasar pembobotan dengan menggunakan metode weighted objective. Hasil perhitungan dari metode tersebut jenis baterai Li-ion memperoleh nilai 280, NiMH memperoleh nilai 270, dan lead acid memperoleh nilai 220. Nilai tersebut dapat dijadikan referensi sebagai tingkat kelayakan untuk implementasi baterai kendaraan listrik roda empat di Indonesia.
