Food industries in a country depend on the packaging system to preserve the product commonly use the plastic based material. Generally, commercial plastic type for packaging in Indonesia are Polystirine (PS) and Polyvinyl Chlorida (PVC). One of problem in home industries (UKM) especially in food sectoris to find the appropriateand particular packaging for their food products. Vacuum Thermoforming machines commonly used by industries to provide the packaging product. However, the forms and materials for the product are too general. In order to provide specific forms for definite products, small-scale vacuum forming machines produced by other countries can be found in the market. Nevertheless, the price still considered high for a home industrial entrepreneur. This study investigates the appropriate automatic control system for the designed small-scale industrial vacuum forming. The control decision achieved via a software based on LabView through a laptop. Thus, it can be displayed, monitored and also being recorded continuously. The test shows that the heater stable at 20 minutes meanwhile the plastic sheet can be shapedafter 15 minutes heating process.Keywords: Plastic, vacuum forming, home industry, automatic.ABSTRAKIndustri makanan yang jumlahnya cukup besar di Indonesia tidak dapat lepas dari proses pengemasan terutama penggunaan kemasan plastik. Jenis plastik yang banyak digunakan untuk kemasan makanan adalah Polystirine (PS)dan Polyvinyl Chlorida (PVC) yang umumnya dijual bebas di pasar/ toko dengan ukuran yang sudah spesifik. Masalah yang banyak dihadapi oleh industrik kecil menengah (UKM) umumnya adalah kesulitan dalam penggunaan kemasan yang sesuai baik ukuran maupun bentuk dari produknya. Mesin Vacuum Thermoforming seperti yang dimiliki oleh industri untuk produk kemasan umumnya memiliki skala yang besar dan memiliki jenis serta bentuk standar. Sementara mesin dalam skala kecil masih dirasa cukup mahal dari segi biaya karena produk dari negara luar. Karenanya mesin Vacuum Forming otomatis skala UKM dengan biaya yang ekonomis ini sangat penting. Penelitian ini ditujukan untuk melakukan otomatisasi dari karakter pemanas yang digunakan dengan mempertimbangkan posisi optimal agar dicapai unjuk kerja yang optimal dari system yang sudah dibuat. Keputusan dari pengendalian alat dilakukan menggunakan software LabView melalui laptop. Oleh sebab it, data dapat ditampilkan, dimonitor serta disimpan secara langsung dan terus-menerus. Hasil uji fungsi menunjukkan bahwa pemanas bekerja dengan stabil setelah 20 menit sedangkan obyek plastik dapat dibentuk setelah dipanaskan selama 15 menit.Kata kunci: Plastik,,Vacuum Forming, UKM, otomatis.
A braking system is an essential value in a vehicle particularly for a safety precaution. The higher number rate of traffic accidents mostly in Indonesia shows that the dominant cause of accidents is due to the human factor. The physical condition such as tired or sleepy during driving is the primary problem according to the survey. In order to assist a person when driving a vehicle, an artificial intelligence method is necessary to be integrated to ensure the safety of surrounding people inside and outside the vehicle. This study focuses on implementing the method of identifying object and distance to provide an indicator for braking action. Images from a stereo camera is processed by a neural network technique via a mini computer to classify as well as the distance of objects. Furthermore, selection of priorities are done to obtain the intensity of braking action. The result shows that process of classification and measurement requires period around 200 ms. Furthermore, braking action done by fuzzy controller sub-system shows that the intensity has smoother signal with the object distance variation compare to the direct method. Objects are firstly identified by the presence of a stereo camera, later on the decision of braking intensity is generated by two processing unit namely conventional and fuzzy unit. This is achieved by processing the data saved from the object detection using two system via MATLAB software. The object identification result, distance measurement and the period of object detection is presented. Moreover, the response of braking intensity using data is processed with both conventional and fuzzy unit systems are also presented. he implementation of this study is for the heavy vehicle such buses or trucks that requires higher safety during the journey.
Research related to the magnetization of fossil fuels is currently believed to be able to improve the quality of combustion due to the cluster decluster effect on the fuel. Fossil fuels are finite and non-renewable. Meanwhile, non-fossil energy, especially bioethanol, despite having more environmentally friendly exhaust gas emissions and higher octane rating than gasoline, has a lower calorific value than gasoline. To overcome this deficiency, the fuel magnetization of a mixture of gasoline and bioethanol is carried out. The fuel is used in 4 stroke injection motorcycles. Furthermore, the performance of the 4-stroke injection motorcycle was observed. the fuel mixture without magnetization was used as a control variable. The intensity of the electromagnetic field used is less than 2,000 Gauss, this is different from previous analysts. As a result, the magnetized motorcycle experienced an increase in torque of 4.48 – 7.30%, power of 4 – 9.90%, and a decrease in SFC of 6 – 9.20%.
Pengabdian Kepada Masyarakat merupakan salah satu poin penting Tri Darma Perguruan Tinggi. Jurusan Teknik Mesin, Politeknik Negeri Jakarta, tahun 2019 ini mengadakan program Pengabdian Kepada Masyarakat dengan mengangkat tema “Alih Teknologi Perawatan Otomotif Untuk Meningkatkan Life Skill Mekanik Sepeda Motor di Kampung Pulo Geulis, Kelurahan Babakan Pasar, Kecamatan Bogor Tengah, Kota Bogor.” Perawatan dasar sepeda motor memang dibutuhkan bagi setiap yang memilki kendaraan. Akan tetapi tidak semua yang memiliki kendaraan bermotor bisa memilki kemampuan memperbaiki sepeda motornya. Tujuan dari pengabdian masyarakat ini adalah untuk membekali para peserta agar memiliki keahlian dalam merawat sepeda motornya, khususnya untuk perawatan dasar. Selain itu, tujuannya agar para peserta memilki pekerjaan yang berkaitan dengan otomotif. Jurusan Teknik Mesin, Politeknik Negeri Jakarta memberikan pelatihan sekaligus menghibahkan seperangkat peralatan (toolbox) untuk perawatan sepeda motor dengan memanfaatkan alat dan bahan yang relatif mudah diperoleh. Pertimbangannya, jika para peserta tidak dibekali peralatan perawatan sepeda motor, para peserta akan kesulitan untuk terus menggali mengaplikasikan ilmu yang diperoleh selama pelaksanaan pembejkalan. Metode yang digunakan untuk mencapai tujuan adalah dengan cara: 1) pembekalan teori tentang perawatan dasar sepeda motor. 2) praktik perawatan dasar sepeda motor. 3) bantuan perangkat perawatan dasar sepeda motor. 4) pendampingan. Hasil kegiatan dapat disimpulkan yakni kemampuan peserta tentang perawatan dasar sepeda motor meningkat setelah mengikuti kegiatan pelatihan ini. Hal tersebut dikarenakan pelatih menggunakan metode teori-praktik, dan peserta dibekali peralatan dan bahan untuk mempraktikkan sendiri sepeda motornya. Sehingga antusiasme peserta untuk mempraktikkan ilmu perawatan dasar sepeda motor juga meningkat.
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.
