Abstract

Design is a form of plan, which can be proposals, drawings, models, or descriptions in order to produce an object, system, component, or structure. Designing is the first step in the manufacture of the product. Springbed is one type of bed that is widely used by the public, especially the middle class and above. Consumer needs continue to increase so that the required design new products that can meet the dynamic needs of consumers at PT. XYZ which springbed product’s sales decreased by 10 %. This study is intended to determined quality desain product according to consumer needs. Quality Function Deployment (QFD) is a method which translates customer needs to technical characteristics that can be intervened by the company. The relation of customer needs and technical characteristics is clarified by using Analytic Network Process (ANP). QFD-ANP method used to get a clear picture of the needs of consumers and more objective so as to look for factors that need to be repaired or upgraded. QFD-ANP approach result show that the technical characteristics of the mattress’s thickness, the size of the coils/spring, mattress’s brightness color are important technical characteristics to be improved with the degree of importance respectively 23,83 % , 23,42 % , and 20,33 % .

Abstract

Fasilitas kesehatan masyarakat adalah komponen dalam mempercepat peningkatan derajat kesehatan masyarakat. Rumah sakit sebagai sarana kesehatan memiliki peran yang sangat strategis dalam memberikan layanan berkualitas sesuai dengan standar yang ditetapkan dan dapat menjangkau seluruh masyarakat. Satu instalasi yang membutuhkan peningkatan kualitas adalah instalasi Hemodialisis. Jumlah pasien meningkat setiap tahun harus diikuti dengan peningkatan kualitas layanan instalasi. Meningkatkan kualitas pelayanan rumah sakit tidak dapat dipisahkan dari setiap instalasi atau bagian yang terdapat di rumah sakit, salah satunya adalah fasilitas hemodialisis. Penelitian ini berfokus pada kebutuhan emosional operator mesin hemodialisis (perawat) untuk desain mesin hemodialisis melalui Kansei Engineering.

Abstract

Some flower pots are made of plastic materials. Plastic waste is a global environmental issue with varying quantities and types in different countries. One source of plastic pollution is low-durability plastic pots, commonly used for seeding in agriculture, horticulture, and forestry. Waste from these plastic pots is difficult to decompose by soil microbes, thus posing an environmental contamination risk. Life Cycle Analysis (LCA), also known as life cycle assessment, is a method to measure the environmental impacts of products, such as biofuels. In LCA, researchers prepare an inventory of the resources used (e.g., fossil fuels and raw materials) and substances produced (e.g., greenhouse gases, solid waste, and other pollutants) throughout the full life cycle of production, transportation, and use of the product in question. From this inventory, researchers conduct impact assessments that estimate the final effects on human health, ecosystem function, and depletion of natural resources. This study aims to assess the life cycle analysis of plastic flower pot products from  their initial material stage to their disposal as waste, in order to gain insights into the potential  for minimizing their environmental impact. The results of research where the production of 600 ml plastic flower pot bottles required 28 grams of plastic resin per bottle, as well as energy for the production and transportation processes. Plastic packaging production produces defective products.

Abstract

The business of making chips has two main products namely peyek chips and banana chips. Making peyek chips and banana chips is done manually using a very simple production facility. The process of frying chips requires a long time because the craftsman only has 1 stove and 1 pan so that the frying process is carried out alternately between peyek and banana chips. This has an impact on a limited quantity of projects so that often customer requests cannot be fulfilled. The quality of chips produced sometimes does not satisfy consumers because it is not crispy if stored for a period of time. This is because the crafters use thin plastic and the process of adhesion to the packaging activities is carried out using candles and kerosene lamps. In addition to not sticking to plastic, there is also a hollow plastic package so that air can get into the chips. The dedication team provided solutions to increase production in the form of 2 units of high pressure cookers, 1 unit of furnace, 3 units of iron frying pan, 1 unit of plastic packaging adhesive (sealer), 1 unit of mechanical sweet potato slicer, 1 unit of semi-mechanical banana slicer, procurement brands and thick plastic. Utilization of these production facilities results in the addition of the types of products produced, namely tojin beans, sweet potato chips, pan flowers and rengginang. Increasing the quality and quantity of products has an impact on increasing the market so that it has been marketed to simple housing, medium housing complexes and now modern outlets are willing to accept the products produced.

Abstract

Aqila Wash Station is a micro business that washes motorcycles, mats and carpet in Deli Tua, a sub-district in North Sumatra province. Washing motorcycle may consume a large amount of time and this decreases customers’ satisfaction. The whole process is performed manually using very simple tools and this tires the workers quickly, which results in a decrease in their work quality. The most common problem that workers face is soap depletion. The next problem is compressor machine becomes hard to initiate, which makes the washing duration longer and may even cause customers to go to another motorcycle wash station. This service activity helps the wash station by providing a compressor machine and a set of hydraulic tools to raise and lower the motorcycle. The floor, where the motorbike is washed, is leveled, and then a steam machine and soap are provided. This service activity also includes giving assistance to the workers, rotating the material given, providing internships chance to students, and teaching few concepts of science and technology. It is expected that workers effectiveness will improve the work quality of Aqila Wash Station.

Abstract

This community service activity brought about a change in the process of cutting “kerupuk jangek” by providing a mechanical cutting tool powered by a dynamo, along with an adjustable cutting size capacity of 200 kg/hour. Previously, the production process of “kerupuk jangek” was done manually, but the cutting process was time-consuming. Craftsmen used to cut the skin while sitting on a 45 cm high wooden bench. Their right hand continuously operated the knife with the right shoulder raised, while the left hand held the sheet of skin and the neck was bent. Every day, the craftsmen manually cut 240 sheets of shin with a knife for 3 hours of work. The manual process often resulted in tired fingers and accidents where their fingers came into contact with the knife blade due to fatigue and the absence of a barrier between their finger and the knife blade. The delayed cutting process also affected the drying process, preventing the “kerupuk” from expanding properly during frying and causing a defect rate of more than 5%. The method used in this activity is providing information, training and assistance in using ergonomic work facilities. The use of the mechanical cutting tool resulted in a shorter buffalo skin-cutting process, and craftsmen were fed from bodily discomfort and potential injuries caused by contact with the knife blade.
