Abstract

Wudu is a routine activity carried out by Muslims before performing the prayer, and mosques are the most frequently visited places for performing prayers. A mosque is a social facility of a city or region. The comfort of a mosque is an important factor in seeing the comfort of a city or region. The wudu facility is the main facility in a mosque that needs attention, an ergonomic wudu facility will provide comfort for visitors. The city of Banda Aceh, as the capital of Aceh province, holds the status of an Islamic Sharia region, it is important to provide social facilities such as a mosque that provide a sense of comfort for its residents and visitors. The wudu facility from mosques in the city of Banda Aceh is relevant to be researched and discussed to see the level of comfort. From 20 samples of mosques in Banda Aceh City that has observed, it was found that in general the mosques in the city of Banda Aceh do not yet have wudu facility that meet design standards in accordance with the ergonomic concept. There are only 2 mosques (10%) found where wudu facility meets the standard ergonomic design, and even then, it is only for the standing position of wudu facility. In general, the dimensions of the wudu facility that meet the ergonomic design standards are the height of the faucets from the floor, while the distance between the faucets and the distance between the faucets and the standing / sitting position does not meet the standard. This is a note for the Banda Aceh City Government to pay more attention to the services of social facilities in its region, so that improvements can be made in the future.

Abstract

Some of the characteristics of virgin coconut oil are to produce products with lower water and acid content, clear color and have a long shelf life of 12 months. Pure coconut oil is growing rapidly not only for household needs, but is widely used for cosmetics and medicine. From an economic point of view, virgin coconut oil has a higher selling price than coconut oil which is traditionally processed by heating coconut milk or depositing coconut milk for a long time, resulting in a rancid odor and poor quality due to high water and free fatty acid content. Therefore, research on the heating process was carried out to obtain virgin coconut oil with lower water content and free fatty acids according to SNI. There are 3 methods of making virgin coconut oil, namely the method of fermentation, inducement and heating. The method used in this research is the gradual heating method, the heating method is tested with gradual heating or one heating, for gradual heating, preheating is carried out at a temperature of 60-110°C with 9 hours of drying time and final heating with a temperature variation of 60°C ( sample A), 70°C(sample B), 80°(sample C) and drying time of 5 hours, 4 hours and 3 hours. The results showed that the drying air temperature had an effect on product quality and drying time. The results of calculations and tests show that the most effective treatment is sample A with the lowest water content and free fatty acid content reaching 0.08% and 0.10%.

Abstract

Load loading activity is a work condition where heavyweight causes excessive energy on working position so that the potential of musculoskeletal complaints and early fatigue disorder occur. Early fatigue can possibly cause illness and accidents which lead to disability and perhaps death. This study aims to produce a supporting design tool for work on load loading activities based on biomechanics and physiology methods regarding workers of the Serikat Pekerja Seluruh Indonesia (SPSI) Banda Aceh, Indonesia. A normal lift restriction is provided by the National Institute of Occupational Safety and Health (NIOSH) consist of a range of aspects of biomechanics and physiology. Biomechanical limitations include the magnitude compression force at 3.4 kN (770 lbs) and physiological limitations include the energy expenditure to a maximum of 2.2 to 4.7 kcal/minutes. Steps and stages processes are taken in the physiology method begun by recording workers’ heart rate/pulse before work while working and at rest. The next stage was calculated workers’ energy expenditure, at the time before work it was at 2,815 kcal/minutes while working at 8.194 kcal/min, and while at rest it was at 5.58 kcal/min. The researcher also calculated the energy consumption of each worker in about 2,614 kcal/min. The measurement of biomechanics method is the measurement of the Recommended Weight Limit (RWL) origin and destination absence supporting tools, and then calculated the lifting index (LI) origin and destination value without supporting work tools. The LI origin was 2.9 and 2.3 to 2.6 destination. So according to LI criteria values were above 1 point which indicated that works were not safe and potentially could cause injury. The value of RWL origin and destination using supporting tools able to count the LI origin and destination value on the condition of using supporting tools, a value obtained was 0.825 LI origin and destination 0.38 to 0.44. It showed the workers were safely done. The conclusion of all stages test conducted in this study is to provide design support tools as a solution for load loading work which allows the slider conveyor concept to move materials from the place of its origin to its destination.

Abstract

Penggurdian merupakan salah satu proses pemesinan yang umum digunakan pada industri manufaktur. Pada proses gurdi gaya potong sangat mempengaruhi hasil dari penggurdian tersebut. Semakin tinggi gaya potong maka semakin besar getaran dan gesekan yang terjadi sehingga dapat menyebabkan kekasaran pada benda kerja dan keausan pada pahat potong. Penelitian ini mempelajari tentang pengaruh parameter pemotongan dan metode Minimum Quantity Lubrication terhadap gaya potong pada proses gurdi. Pengukuran gaya potong menggunakan dynamometer semi konduktor sebagai alat untuk mengukur gaya tekan/gaya potong pada saat proses penggurdian berlangsung. Proses pembuatan lubang ini menggunakan dua jenis metode Minimum Quantity Lubrication yaitu dengan laju aliran 300 ml/jam dan 500 ml/jam, beberapa parameter pemotongan yaitu dengan kecepatan pemakanan (100, 120, 140) mm/min kemudian putaran spindle yang digunakan (800, 1000, 1200) rpm. Berdasarkan hasil pengujian menunjukkan bahwa gaya potong terendah diperoleh pada putaran spindel 1200 rpm dan laju pemakanan 100 mm/min dengan laju aliran 500 ml/jam didapatkan gaya potong 303,50 N, gaya potong tertinggi diperoleh pada putaran spindle 800 rpm dan laju pemakanan 140 mm/min tanpa menggunakan media pendingin didapatkan gaya potong 539,34 N.
