Abstract

Energi listrik merupakan kebutuhan primer dalam kehidupan sehari-hari. Perkembangan teknologi mengakibatkan meningkatnya kebutuhan energi listrik setiap tahunnya. Energi baru terbarukan memasok kebutuhan energi listrik nasional sebesar 14%. Di sisi lain, pemerintah mengharapkan komposisi energi baru terbarukan sebesar 23% hingga 31% pada tahun 2050. Hal ini menunjukan bahwa energi baru terbarukan masih memiliki gap yang cukup tinggi. Penelitian ini merupakan salah satu upaya dalam pengembangan energi baru terbarukan, terutama pada pembangkit listrik mikro-pico hidro. Penelitian ini dilakukan menggunakan metode Computational Fluid Dynamics menggunakan Aplikasi Ansys dengan CFX Solver. Penelitian dilakukan untuk mengetahui pengaruh jumlah sudu pada hidro-turbin cross-flow terhadap performa Coefficient of Power. Peneltian dilakukan pada rotor dengan dimensi diameter 80 mm, panjang 130 mm dan sudut sudu 15°. Variasi jumlah sudu dilakukan pada jumlah sudu 8, 12, 16, dan 20. Simulasi dilakukan pada steady state, dan menggunakan tipe turbulen Shear Stress Transport. Turbin cross-flow beroperasi pada kecepatan air 3m/s dengan kecepatan sudut pada interval 50 sampai 350 RPM.  Hasil menunjukan Coefficient of Power Maximum yang dihasilkan untuk sudu 8,12, 16 dan 20 adalah 10,8%; 14,1%; 16,8% dan 20,1%. Dari hasil tersebut menunjukan performa maksimal dihasilkan oleh hidro-turbin tipe cross-flow dengan jumlah sudu rotor 20.

Abstract

The method of producing items through synchronously depositing material level by level, based on 3D digital models, is named Additive Manufacturing (AM) or 3D-printing. Amongs many AM methods, the Fused Deposition Modeling (FDM) technique along with PLA (Polylactic acid) material is commonly used in additive manufacturing. Until now, the mechanical properties of the AM components could not be calculated or estimated until they've been assembled and checked. In this work, a novel approach is suggested as to how the extrusion process affects the mechanical properties of the printed component to obtain how the parts can be manufactured or printed to achieve improved mechanical properties. This methodology is based on an experimental procedure in which the combination of parameters to achieve an optimal from a manufacturing experiment and its value can be determined, the results obtained show the effect of the extrusion process affects the mechanical properties.

Abstract

This research was taken at one of the mechanical engineering companies produces customize spare parts, special purposed machinery, automation system integrator and robotic installation. The company has problem high cost operation warehouse, need space expanding production line, stockopname problem, picking failure, high cycle time operation, logistic efficiency, and inventory cost. These problems have impact to company performance which need cost down, increase efficiency and productivity with minimum defect. The data has shown company needs additional 157m2 to expanding new line, has 4% picking defect, there is 200 million operational cost over, 150sec cycle time, 7% lost part and risk cyber data security. Due to the importance of the problem, the company needs to evaluate and solve the problem which has impact to company performance, especially in the warehouse. DMAIC (Define Measure Analyze Improve and Control) approach is applied to comprehensively explore the problem and comes out with alternatives solution. Two alternatives were developed. The criteria for selection used were i.e. cost; accuracy, security, safety, productivity, cycle time, and minimize defect It was concluded that the application of automated storage and retrieval system (ASRS) was selected as it dominates in many aspects compare to expanding the current one. This implementation of ASRS approved that this new system answers the current warehouse problem

Abstract

Saat ini di indonesia sepeda motor merupakan alat tranportasi yang sudah di produksi massal. penggunaan sparepart sepeda motor antara yang merek satu  dengan merek yang lainnya sudah umum dilakukan dikarenakan komponen tersebut terkadang sulit didapatkan di pasaran. Entah karena sparepart sepeda motor tersebut tidak lagi diproduksi oleh pabrikan atau memang ada faktor-faktor lain yang mempengaruhinya. Poros adalah salah satu komponen sepeda motor , dimana poros  merupakan salah satu bagian yang terpenting dari setiap mesin. Peranan utama sebuah poros adalah untuk mentransmisikan daya dari satu elemen mesin ke bagian elemen mesin lainnya. Daya tersebut dihasilkan oleh gaya tangensial dan momen torsi yang hasil akhirnya adalah daya tersebut akan ditransmisikan kepada elemen lain yang terhubung dengan poros tersebut. Poros roda merupakan salah satu komponen yang saangat penting dari sebuah sepeda motor karena poros berfungsi untuk menopang body, beban kendaraan itu  sendiri maupun beban luar pada kendaraan dalam hal ini manusia atau barang muatan pada sepeda motor. Sehingga di perlukan  poros yang baik untuk mencapai fungsi dari poros tersebut. Dipenelitian ini akan  membahas tentang Poros dengan beban puntir dan lentur yang bertujuan untuk memberikan pengetahuan tentang poros depan, Lebih menambah wawasan pengetahuan dalam  bidang otomotif dan Mampu merencanakan secara sistematis elemen-elemen mesin yang ada pada system kerja poros. Perhitungan Beban Luar, Perhitungan Diameter Poros, Jadi hasil dari  perhitungan poros bahwa diameter 9.9 mm aman digunakan sesuai  dengan standard,  dengan diameter poros actual dilapangan yaitu 10 mm

Abstract

Almost every year, floods disaster becomes the scourge of many countries in the world, including Indonesia.  When the flood comes and submerges the houses, every item and household furniture in it will also be submerged in flood water. Furniture that is heavy and difficult to move, especially electronic equipment such as refrigerators, may be left by the owner when a flood occurs. To prevent the furniture from submerging, a lifting kit is needed. For this reason, the purpose of this work is to design a mechanical tool/kit that can lift or elevate the electronic furniture such as refrigerator to a higher position and avoid the damage caused by flood. The kit is expected to be able to cover a 100 x 80 cm base of the refrigerator with maximum load of 200 kg. The elevation of the lifting kit is set to be higher than 50 cm. Calculation for the stress and fatigue analysis is also performed to determine the strength of the structure. As a result, the obtained safety factors for the critical components under static and fatigue loading conditions show values of more than one, indicating the product is safe for real operation. In addition, the required torque to produce the elevation is also calculated and discussed.

Abstract

The need for sliced scallions is relatively large, so a tool that can assist in the slicing process is more effective both in terms of energy and time spent. Based on these problems, the idea was born to design a scallion slicing machine to help the community in slicing scallions, especially food sellers who need scallions such as egg martabak sellers, and food sellers.The method used is literature study (library), field observations, and problem-solving methods in the form of design which includes pre-planning in the form of machine sketches, machine concept planning, calculations, making working drawings, procurement of materials and components, toolmaking, assembly, and testing.The output of this final project is the manufacture of a scallion slicing machine that is simple and effective by not forgetting the safety and hygiene factors so that it can support the slicing process at the scale of traders and home industries. This tool has a capacity of 300 grams per minute using a DC 775 motor and is sourced from four 18650 li-ion batteries.
