Abstract

Lighting planning in a laboratory room is one of the factors in designing to produce good and energy efficient lighting. To carry out all activities in the room of a laboratory, sufficient lighting intensity is needed, so that it can be carried out optimally, especially with regard to practicum work carried out in the laboratory for the benefit of the learning process. In terms of quality, lighting in a room is in the form of strong lighting or illumination level. The purpose of this research is to design, identify and evaluate the recommended lighting intensity / quality with the lighting standards from the existing lamp data installed in the electrical and measurement laboratory. The results of the measurement research for the Electrical Machinery and Measurement Laboratory obtained that the average light intensity for the work point of the practicum table is 127 lux, so that the light intensity is still low according to the SNI 16 - 7062 - 2004 standard with a measuring point of even lighting distribution obtained by 137 lux. If the light intensity of a laboratory is not fulfilled, it will result in inconvenience for students in carrying out the measurement practice, especially for practicum electrical circuits by calculating the value of the ring resistor. For this reason, the intensity of lighting in the laboratory room must be designed to meet the recommended lighting standards for a laboratory, namely 300 lux, namely by adding the number of 8 points of TL Philips Lifemark 36W / 54-765 lamps,or 8 points of 25 W / 2600 lumens LED lamps, or 6 Philips CLF 55 W / 3465 lumen type light point.

Abstract

The limitations of the production laboratory in the form of providing tools can hinder turning activities. Based on the competency test scores in the basic machining practicum for the 2018/2019 academic year, it was found that there were still many UPI FPTK DPTM students who did not pass the competency test by 82% (23 people). This indicates that students still have difficulty turning. Student difficulties include the ability to produce work objects that do not exceed tolerance limits and the ability to take the time set in each turning work. The purpose of this study is to design a tool called Emergency Stick Level (ESL) which is used in the basic plus type 100809 lathe. The design of the Emergency stick level (ESL) includes the manufacture of butterfly nuts, stick level stoper), springs (springs), ESL housing (ESL body) and connecting nuts (extention nut). Aluminum was chosen as the basic material for making Emergency stick level (ESL) because it is easy to shape and corrosion resistant. The conclusion is that the presence of the Emergency stick level (ESL) makes it easier for UPI FPTK DPTM students to turn

Abstract

Sulfur dioxide (SO2) is an irritant gas at concentrations above 250 g/m3 which can cause respiratory problems. Sources of SO2 come from burning fuel containing sulfur. Measurement of SO2 levels in the air using the Tetrachloromercurate (TCM)/Pararosanilin method. PT "B" is a processed wood product company with production using sodium metabisulfite as a mixture for making glue for one type of process product. The purpose of this study was to study the interference of sodium metabisulfite in the measurement of SO2 in the air using the Tetrachloromercurate (TCM)/Pararosanilin method. This research is descriptive observational to explain the phenomena found in monitoring the concentration of SO2 based on SNI 7119-7:2017. The SO2 concentration in the 2017 – 2019 RKL-RPL monitoring results at the glue mixing location was 7-191 g/m3. In the second semester of 2020 measurement, the SO2 concentration was measured at the glue mixing location when the product used sodium metabisulfite as an additive. The activation of SO2 is as follows: activation of the mixer after the process is 646 g/m3, filling the glue mixer is 291 - 314 g/m3, the activity without the use of sodium metabisulfite is 11 - 13 g/m3. The results showed that the concentration of SO2 when the product used a mixture of sodium metabisulfite was higher than the concentration of SO2 when the product did not use sodium metabisulfite. Based on the results and analysis, it can be said that there is an interference of metabisulfite compounds in SO2 measurement due to the absorption of sodium metabisulfite by TCM. This research is helpful for contamination parameters in the workplace  and the threshold determination and reducing the accident and occupational illness caused by exposure to chemicals through controlling and controlling potential hazards.
