Abstract

The use of delivering material to students. Students who carry out practicum in the Lab. chasiss Mechanical Engineering, State University of Surabaya still does not have a hydraulic power steering system trainer / trainer as a learning medium in chasiss technology courses and especially chasiss practice. The reason we designed the trainer was to improve the students' ability to understand the steering system, especially the type of hydraulic power steering appropriate media can determine success in learning. Learning media are almost never separated from being used by lecturers in. Some components are blocked or covered by other components, so it is quite difficult to learn. the trainer hydraulic power steering system. The results of the hydraulic power steering system trainer test are that when the steering is straight, turning right and left it is concluded that when the steering is straight the pressure on the hydraulic pump does not transmit fluid to the system at a specified rpm, and when the steering wheel turns right the hydraulic pump is fully distribute fluid to the system at rpm 1700 = 60 Psi, 1000 rpm = 30 Psi and 700 rpm = 20 Psi and at the steering wheel turn left 1700 rpm = 50 Psi, 1000 Rpm = 30 Psi and 700 rpm = 20 psi seen at the pressure gauge, The results of the frame vibration test are aimed at 700 = 0.53 m/s2 rpm and an increase at 1700 rpm = 3.53 m/s2. Keywords: Learning Media, Steering System, Hydraulic Power Steering.

Abstract

The control system trainer as a medium for students and lecturers to make communication and learning effective so that the teaching and learning process becomes more effective. There is still no instructional media trainer for learning in the chassis technology subject at the State University of Surabaya for the hydraulic power steering control system, which can easily be understood and studied by students, especially mechanical engineering. Therefore, the authors make learning media that discusses the workings of the power steering control system and can find out the pressure generated from the hydraulic power steering. R&D (Research and Development) method or experimental-based development design. With the aim of being able to determine the specifications of the main drive components that will be used in the design and build of a hydraulic power steering control system. The results of the analysis of the pressure test work show that the pressure generated from various speeds shows different results, so that it affects the weight of the steering system. For hydraulic power steering at low speed the steering will feel heavy but at high speed conditions the steering will feel light. The implication is that the pressure in the steering system is directly proportional to the speed of the vehicle. The results obtained from the power steering pressure when turning right with a speed of 700 rpm at 20 Psi, 1000 rpm at 30 Psi, 1300 rpm at 40 Psi and 1700 at 60 Psi. while when turning to the left, the results obtained at rpm 700 of 20 Psi, rpm 1000 of 30 Psi, rpm 1300 of 40 Psi and rpm 1700 of 50 Psi.

Abstract

UKM Jamu Bu Luluk merupakan industri rumahan yang bergerak di sektor minuman yang terletak di kelurahan Rungkut, Surabaya. Berdasarkan survey yang kami lakukan permintaan pasar akan produk jamu mencapai 250 botol/hari. Sedangkan UKM Jamu Bu Luluk hanya mampu memproduksi 50 botol/hari. Salah satu permasalahan pada proses pengisian minuman jamu masih menggunakan cara konvensional, yaitu dengan menggunakan corong dan gelas kecil sehingga membutuhkan waktu yang lama dan sering terjadi tumpah pada proses pengisian. Untuk mengatasi permasalahan diatas maka diperlukan suatu teknologi tepat guna berupa Mesin Pengisi dan Penakar Jamu Semi Otomatis berbasis timer dan sensor ultrasonik. Dalam penelitian ini penulis bertujuan hanya membahas desain sistem kontrol, keakurasian kinerja sensor ultrasonik dan keakurasian volume pengisian. Metode analisis data deskriptif kuantitatif diterapkan dalam perancangan ini yaitu dengan mendeskripsikan data secara sistematis faktual dan akurat, selain itu pemilhan komponen yang digunakan juga telah disesuaikan dengan kebutuhan yang ada. Pada bagian hadware, Arduino UNO digunakan sebagai kontrol utama alat dan sensor ultrasonik HC-SR04 sebagai sensor pendeteksi adanya sebuah botol. Berdasarkan dari hasil pengujian sensor ultrasonik HC-SR04 dan Kekauratan volume Pengisian didapatkan untuk rata-rata akurasi keberhasilan sensor yaitu sebesar 97,3% sedangkan untuk nilai keakuratan volume pengisian sebesar 99,59%. Kesalahan pengukuran umumnya disebabkan karena pengaturan delay waktu pada program yang kurang tepat. UKM Herbal Mrs. Luluk is a home industry engaged in the beverage sector, located in the Rungkut village, Surabaya. Based on the survey we conducted, the market demand for herbal products reached 250 bottles/day. Meanwhile, UKM Jamu Mrs. Luluk is only able to produce 50 bottles/day. One of the problems in the process of filling herbal drinks is still using the conventional method, namely by using a funnel and small glasses so that it takes a long time and often spills during the filling process. To overcome the above problems, an appropriate technology is needed in the form of a semi-automatic herbal filling and measuring machine based on a timer and ultrasonic sensor. In this study the authors aim to only discuss the design of the control system, the accuracy of the ultrasonic sensor performance and the accuracy of the filling volume. The quantitative descriptive data analysis method is applied in this design, namely by describing the data in a factual and accurate systematic manner, besides that the selection of components used has also been adapted to existing needs. In the hardware section, Arduino UNO is used as the main control tool and the HC-SR04 ultrasonic sensor as a sensor for detecting the presence of a bottle. Based on the test results of the ultrasonic sensor HC-SR04 and the accuracy of the filling volume, the average accuracy of the sensor success is 97.3% while the accuracy of the filling volume is 99.59%. Measurement errors are generally caused by improper time delay settings in the program.

Abstract

UKM Ibu ira merupakan usaha dagang yang memproduksi pentol bakso skala rumahan. Di dalam proses produksi Pentol bakso , UKM ini mengerjakan seluruh proses produksinya secara manual dengan alat-alat konvensional. UKM ini mengalami kesulitan pada proses penggilingan daging yakni waktu produksi melambat karena masih menggunakan cara konvensional, sehingga total pengilingan adalah sekitar 2 kg / 30 menit, maka total produksi pengilingan dalam sehari 2 kg dan lebih pada waktu hari raya. Padahal, UKM Ibu Ira sudah dikenal di daerah Krian Sidoarjo, jumlah permintaan pasarnya cukup banyak,sehingga UKM ini tidak mampu memenuhi permintaan pasar yang menyebabkan persebaran produk terhambat. Pada metode perancangan dilakukan dengan mendesain rancang bangun mesin pengiling Daging semi Otomatis.Adanya mesin penggiling Daging Semi otomatis digunakan untuk proses penggilingan Daging secara cepat dengan tingkat pengilingan yang tepat. Selain itu mesin ini di dilengkapi dengan motor bensin untuk pengerakkan alat supaya tidak dikerjakan secara bekerja secara manual. Adanya alat pengiling daging semi otomatis ini diharapkan mampu menjawab permasalahan yang dialami saat proses penggilingan dan akan dikomersilkan menjadi sebuah mesin yang utuh. Ibu Ira's UKM is a trading business that produces home-scale meatball sticks. In the meatball pentol production process, this UKM does the entire production process manually with conventional tools. This UKM has difficulty in the meat grinding process, namely the production time is slowing down because it is still using the conventional method, so the total grinding is about 2 kg / 30 minutes, so the total milling production in a day is 2 kg and more during holidays. In fact, Ms. Ira's SMEs are well known in the Krian Sidoarjo area, the number of market demands is quite large, so these SMEs are unable to meet market demand which causes product distribution to be hampered. Semi-automatic is used for the process of grinding meat quickly with the right level of grinding. In addition, this machine is equipped with a gasoline motor to drive the tool so that it is not done manually. The existence of this semi-automatic meat grinder is expected to be able to answer the problems experienced during the grinding process and will be commercialized into a complete machine.

Abstract

Suspension technology on the vehicle provides a comforting effect with shock absorbers and a safety effect in driving and reducing the accident rate. The suspension system was developed by changing the construction and mechanism as well as the addition of a control element. Variable Geometry Suspension (VGS) is the development of a suspension system by using an active actuator is Single-link which is used to change the geometry of the suspension. Geometry change can affect the performance of the suspension system, so a modeling approach is needed to analyze the performance of the VGS system. The VGS modeling uses a quarter-vehicle model and a multi-body model with an equation of motion system using a Kineto-dynamic model with a double-wishbone suspension type. The analysis method on the VGS uses input is bumpy-road to obtain system performance in body acceleration, suspension deflection, and tire deformation. The results of the VGS with the Kineto-dynamic model has a range of 2 mm in the variation of the single-link angle, the performance values ??in the body acceleration and tire deformation between the quarter-vehicle and multi-body models have the same oscillations until steady, while the suspension deflection in the Kineto-dynamic model differs in the first oscillation with a steady time of 1.6 seconds. Therefore, the Kineto-dynamic model can be used to approximate the actual system.
