Abstract

Temperatur udara ambient berpengaruh pada performa turbin gas. Temperatur yang tinggi mengakibatkan masa jenis udara menjadi rendah sehingga pada laju aliran udara masuk kompresor lebih sedikit. Teknologi untuk memitigasi permasalahan ini adalah penggunaan Turbine Inlet Air Cooling (TIAC) pada inlet air system turbin gas. Penelitian ini bertujuan untuk mendesain air cooler dengan tipe staggered continous finned tube compact heat exchanger pada turbin gas Lm6000 milik PT.X di Karawang. Proses perancangan air cooler dilakukan dengan  menggunakan perhitungan Kern. Data yang dibutuhkan dalam penelitian ini adalah data dimensi maksimum air cooler, data temperatur air pendingin, data pengoperasi turbin gas dan data bahan bakar yang diambil sebelum dan sesudah pemasangan TIAC menggunakan beban turbin gas yang sama yaitu 22 MW. Hasil yang didapat dari proses perancangan air cooler adalah desain air cooler dengan 187 tube bundle dan nilai koefisien konveksi keseluruhan sebesar 35,4 W/m²°C. Analisis performa turbin gas menunjukkan bahwa temperatur inlet low pressure compressor mengalami penurunan rata-rata sebesar 3,5°C, sementara efisiensi siklus rata-rata meningkat sebesar 1,65%. Adapun peningkatan daya bersih rata-rata sebesar 0,496 MW karenanya dapat menghasilkan  penghematan biaya bahan bakar sebesar Rp1.554.257.011 per tahun.

Abstract

Ban adalah salah satu komponen penting dalam pertambangan khususnya alat angkut/alat berat pada PT SBI. Guna memenuhi tuntutan produksi diperlukan jam kerja yang tinggi dari alat angkut, menyebabkan kinerja dari ban semakin berat dan berisiko untuk mengalami kerusakan. Kondisi yang terjadi saat ini dari tidak langsung terdatanya penggantian ban serta kurang efisien karena diperlukan dua tahapan dan dilakukan oleh orang yang berbeda dalam melakukan inspeksi harian dan bulanan sehingga memerlukan waktu lebih. Hal tersebut dapat menyebabkan peramalan menjadi tidak maksimal, akibatnya terjadi downtime karena menunggu part ban. Oleh karena itu solusi diberikan dengan membuat aplikasi sistem manajemen ban berbasis web yang dapat mempermudah memasukkan dan memonitoring data ban menggunakan database online. Diharapkan dengan digitalisasi ini dapat menciptakan efisiesi waktu dan efektif serta dengan jangkauan kerja yang luas. Proses ini akan dilakukan menggunakan aplikasi web yang telah dirancang menggunakan metode perancangan dengan UML, Laragon, dan pengembangan aplikasi menggunakan framework Laravel. Dengan aplikasi ini pekerjaan pendataan dan monitoring menjadi lebih cepat sebesar 99,4%, terjadinya paperless, lokasi akses yang luas, dan dapat mencegah risiko lost cost akibat downtime, Serta didapatkan hasil implementasi aplikasi beserta semua fiturnya yang sesuai harapan dengan hasil kuesioner adalah 80-100% atau sangat setuju dengan pertanyaan yang diajukan pada responden.

Abstract

Implementation of software design for vacuum forming machines is the focus of this paper. This vacuum forming machine will be used for small and medium industries (IKM) in food in Indonesia, where the packaging process is essential. Packaging materials in the food business are polystyrene plastic (PS) and polyvinyl chloride (PVC), which are generally sold freely in specific sizes. The problem that arises in SMEs is the packaging that does not fit, both the size and shape of the product. On the other hand, small-scale packaging machines are still quite expensive in terms of cost because the machines do not originate domestically. Therefore, an IKM scale Vacuum Forming machine with economical costs is needed for the IKM business. Testing software for vacuum forming machines has been running using Labview and Arduino by utilizing serial USB communication with NI-Visa. The experimental results of the designed system have been successfully implemented to the sensors and actuators via the Arduino Uno, indicating that temperature control can stabilize the heat after 3 minutes of heating. Meanwhile, the software that has been designed has been successfully implemented on LabView can monitor and help operators to use the machine easily. Keywords: vacuum forming, food industry, automatic, LabView, pvc.

Abstract

Currently, the application of control systems has been applied in various scientific fields including mechatronics and robotics. Applications in the branch of robotics are also growing day by day not only with conventional controls but also with intelligent systems. An autonomous robot in carrying out certain missions in an unknown environment requires information about the location itself and the environment through the map. A process to identify a position without a map is called a localization function on the robot. Mobile robots building maps and localization are two fundamental tasks when mobile robots work in indoor environments. With 2D laser scanning (LiDAR) data obtained in real-time, the robot can calculate the area of ​​all empty spaces in a room, then can choose the center of the room as its position for map building. The objective of this research is to implement a two-dimensional mapping method using LiDAR. The algorithm used in this study is the Gmapping Technique on ROS. The main purpose of this research is to map mobile robots with LIDAR sensors using the Robot Operating System for navigation and positioning of mobile robots. Through the actual experimental results, the mobile robot will move with a 2-dimensional mapping process.

Abstract

Pada penelitian ini dipaparkan tentang konversi yang dilakukan dengan mengubah kendaraan konvensional berbahan bakar bensin dengan listrik. Penggantian dilakukan dengan melepas Engine penggerak dan menggantikannya dengan motor penggerak yang secara otomatis ditambahkan dengan Baterai sebagai sumber energi. Selanjutnya dari hasil konversi tersebut dilakukan pengujian torsi dan rpm melalui Dynotest yaitu suatu metode pengujian performa mesin kendaraan (motor listrik) dengan cara melihat tenaga (power) dan torsi (torque). Torsi adalah kemampuan mesin untuk menggerakkan atau memindahkan kendaraan listrik dari kondisi diam hingga berjalan dan ketika berjalanpun ada variasi antara kecepatan dengan perubahan gigi yang dilakukan . Selain itu juga dengan Dynotest akan diketahui titik tertinggi nilai Torsi pada setiap gigi. Pada pengujian yang dilakukan didapatkan nilai perubahan gigi yang didapat dari gigi-1 kecepatan maks 20 km/jam, gigi-2 kecepatan maks 40 km/jam, gigi-3 kecepatan maks 60 km/jam dan gigi-4 kecepatan maks 80 km/jam. Pada kendaraan listrik ini pengukuran pada Ampere dan voltase dilakukan guna mengamati performa motor dan baterai sebagai komponen utama dan didapatkan nilai lonjakan pada setiap pergantian gigi.Lonjakan tersebut terjadi akibat dari kombinasi pijakan gas ,rem dan kopling yang bergantian guna mendapatkan nilai akselesari yang nyaman.

Abstract

Electric bicycles with two wheels are increasingly popular as a convenient mode of short-distance transportation. To enhance mobility and promote the use of eco-friendly energy around campus areas, conventional bicycles can be transformed into electric ones using a conversion kit. The main challenge lies in creating a design that is easy to install (plug-and-play) and compatible with various bicycle models. Moreover, monitorized battery condition is an advantage to inform the user. A key advantage of this concept is the inclusion of a universal battery pack equipped with an IoT-based monitoring system. This study aims to design an IOT based battery pack conversion kit powered by a 576 Wh of LiFePO₄ lithium-ion battery type. Experiment results indicate that battery pack of 50 cm × 16 cm × 14 cm dimension with the total weight of 4.5 kg can perform as the energy storage for a converted two-wheeled electric vehicle. The test achieves the speed of 500rpm with 1A current.
