Abstract

Clean water is the primary need of living things because water plays an important role in the process of life. The quality of raw water from various sources has different quality and quantity characteristics, which means that not all regions have a clean water supply that can be processed into water suitable for consumption in accordance with clean water standards that meet clean water requirements. Therefore, in processing and utilizing overflow of Sahang River water, the WTP (Water Treatment Plant) system is to remove metals, organic substances and bacteria in accordance with clean water quality standards of the Ministry of Health of the Republic of Indonesia. The stages in the processing and utilization of the Sahang River water overflow are preliminary analysis of samples in the intake, sedimentation and reservoir tanks. Then to ensure the results of processing and utilization of the Sahang river water overflow, we took a comparative sample, namely PDAM Tirta Musi Palembang water. Analysis of physical, chemical and biological parameters. In the analysis test, the physical parameters of clean water include temperature, color, turbidity, dissolved solids (TDS), smell and taste. In the analysis of clean water chemical parameters, including pH, hardness, chloride, organic substances, ammonia, sulfate, nitrite, nitrate, chromium, cadmium, iron, manganese, copper, aluminum, zinc and lead. Meanwhile, the biological parameter analysis test includes the analysis of E-Coli bacteria. The results of the water quality analysis test for WTP (Water Treatment Plant) have been proven to comply with SNI quality standards for clean water with the optimum results obtained in the addition of a coagulant with a concentration of 75 ppm. However, there are parameters that have decreased and increased levels in each type of parameter such as parameters Turbidity (4.27 NTU), pH (7.01), TDS (24.1 ppm), NaCl (49.7 ppm), DO ( 6.95 ppm), Conducto (1.6211 µs) and hardness (13.29 ppm), but it is still within the standard of clean water quality, which means that the Water Treatment Plant (WTP) system is proven to be implemented especially for water purposes. Laboratory of the Department of Chemical Engineering, State Polytechnic of Sriwijaya and generally for the needs of the community at an economical price and good quality

Abstract

When testing the loading of an electric machine, we often experience problems in finding a tool to see the precision of the connection between the shaft of an electric machine. Shaft connections that are not straight and not right in the middle can damage the shaft of the rotating engine and the engine being rotated. This research is the development of previous research that uses Android phone as a tool. By reading the value of the orientation sensor on an android phone, we can measure the angle of rotation on the x, y and z axes. The Watpasdroid application will display the value on each axis. This application has also been used in the Electric Driving Laboratory at the Surabaya State Electronic Polytechnic (PENS), to check the connection (coupling) between an electric motor and a magnetic load (dynamo meter). The size of a cellphone that is still too large is sometimes become a problem  if the surface being measured is narrow. So we uses a wristband-shaped watch module that already has a gyro sensor and can be programmed according to our need. The size is almost 1/12 of ordinary cellphones. The M5Stick-C module is used to compare the gyro reading value displayed by the wristband. To test the quality of motor joint which  flatness checks have been assisted by using a wristband, a thermal observation camera is used. This application, does not rule out, can be used in other laboratories for the purpose of checking the plane levelness or equality in two dimensions or three dimensions.

Abstract

Risk Assessment is systematic way of carrying out activities in laboratory, identifying the potential emergence of hazards and other worst possibility, and also the decisions to control and prevent the accidents. This research is a qualitative descriptive research with a case study method.  Data obtained through observation, interview, and study documents at Laboratory of Tarbiyah Faculty UIN Sunan Ampel Surabaya. The purpose of this study is to provide an understanding for laboratory users about the importance of implementing occupational safety and health in the laboratory. The result show that there were 14 potential hazards that arose which were divided into four variables, they are handling and storage of materials, design of workshop/laboratory, Facilities, and activities in laboratory. Risk assessment result of 14 potential hazards found that, 43% are low risk, 14% are moderate risk, 43% are high risk, and 0% are extreme risk. The effort to implementing occupational health and safety (K3) have not been fully carried out optimally. To control or push down the potential of hazards are (1) Arranging SOP for implementation of K3, (2) provide Material Safety Data Sheet (MSDS), (3) maximize utilization of personal protective equipment, (4) provide enough first aid and eyewash, (5) provide fire extinguishers (APAR).

Abstract

Borax is a carcinogenic compound which is dangerous to the body. The flame method is one of the qualitative laboratory testing that usually used to determine the Borax compound in food. The method not only needs H2SO4, methanol, furnace equipment which is prices, but also needs long time because of the graying process. The research aims to make a simple borax test kit (simple method) by extracting anthocyanin substances on the skin of purple sweet potatoes and testing the borax compound in food samples. Materials and tools used are purple sweet potato skin, 96% ethanol, filter paper, knives, cutting boards, measuring cups, beaker glass, food scales and petri dishes. The results of the borax test kit that have been made are then tested using the borax standard as the gold standard and it showed that there was color changing of the test kit, i.e from pink to blue. The borax test kit was also tested on four food samples that possibly contained borax, i.e gendar crackers, white tofu, meatballs and noodles. Gendar crackers was the only food sample that contain borax. Therefore, it was concluded that the borax test kit made from filter paper containing anthocyanin can be used as an alternative tool in qualitatively testing of borax in food

Abstract

Pyrolysis of latex gloves waste has been carried out without catalyst at 200°C for 2 h, producing 15.9% liquid, 45.35% gas, and 38.75% residue from 2000 g of waste, where the liquid product contained wax. The liquid product composed of 94.3% hydrocarbon and 5.71% chlorine compound. This research was focused on the removal of wax and chlorine compound in the purpose of increasing  the calorimetric value of the product. Filtration using activated zeolite and distillation at 90ᵒC were choosen to purify the liquid product. The lowest content of wax and chlorine was achieved using filtration techniques. The decrement of wax and chlorine compound in the liquid product increased its physicochemical properties, where the highest calorimetric value was achieved through filtration using activated zeolite, with the calorimetric value of 10715 cal/g.

Abstract

The Skills Lab is a facility where students can practice the skills they need, which is not a real context between doctor and patient. Practicum in the Clinical Skills Laboratory and OSCE uses non-infectious non-medical consumables. The stages of making modification props are carried out in several stages including: collecting and sorting non-infectious non-medical consumables. Disinfection of non-medical consumables that are non-infectious with antiseptics. The produced props include gloves used as prepuce in circumcision beads. Modified infusion plastic bottles resemble human nails we use for nail extraction skills. The IV line can be modified as a vein in the bead, this is used for the sexy vein skill in the beaded IV. Abocart needle (neddle) is used for NGT or usually called sonde for experimental animals. Rubber infusion hose is used as an LED tube rubber ball in Clinical Pathology practicum.
