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.

Abstract

Indonesia is one of the largest rice producing countries in the world (6,905,612,600 tons with a harvested area of 1,344,552,400 Ha). Rice is a national strategy commodity and is consumed by most of the Indonesian population. Rice consumption continues to grow along with population growth. Therefore, rice production must also increase according to the demand for rice needs. The increase in rice production has generally been successful, but the added value obtained has not been fully enjoyed by farmers, especially the high yield loss. The purpose of this research is to make/build a rice thresher machine with a capacity of 100 kg/hour and to get a value for the production capacity of a rice thresher machine with a 6.5 HP machine. This research uses the Research and Development (R&D) method or experimental-based development research, namely by developing a rice thresher machine (thresher).
