EFEKTIVITAS PENCAHAYAAN PADA RUANG BACA DAN RUANG PERKULIAHAN DI GEDUNG BUNG HATTA PROGRAM PASCASARJANA UNJ MENGGUNAKAN SOFTWARE DIALUX EVO 8.2

This research aims to produce of illumination the appropriate lighting in the reading room and lecture room. Because sometimes in the construction of a building, there are still many techicians who have not followed the rules that have been set for appropriate illumination lighting in the reading room and lecture rooms. In this research using a quantitative approach with a descriptive engineering method engineering by utilizing three phases i.e manual measurement, manual calculations and simulated of Dialux Evo 8.2. The manual measurement uses Luxmeter as a measurement to get the value of the measured illumination in the reading room and lecture rooms based on the Standar. The manual calculation uses the calculation method according to SNI. The simulation uses Dialux Evo 8.2 software to optimize the value of the lighting which should be used in the reading room and lecture rooms. The results showed that illumination values were produced in the reading room and the lecture rooms still did not meet the specified Standars. Research do 3 design scenario improvements. The first scenario in the reading room and the lecture room was obtained average optimization percentage of 72% and 57% in the second scenario obtained the optimization percentage 20% s/d 88%, in the third scenario of the light point added, changing the lamp and changing the wall character obtained an optimization percentage of 23% s/d 89%. It can be concluded that the scenario of two is done to Linux obtained some illumination results that conform to the Standars set in the reading room and the lecture room and the value of the deviation generated between the room that is not exposed to sunlight and the room that is exposed the sunlight has a nearby deviation. Abstrak Penelitian ini bertujuan untuk menghasilkan kuat penerangan yang sesuai pada ruang baca dan ruang perkuliahan. Karena terkadang dalam pembangunan sebuah gedung, masih banyak beberapa teknisi yang belum mengikuti aturan yang telah ditetapkan untuk penerangan yang sesuai pada ruang baca dan ruang perkuliahan. Pada penelitian ini menggunakan pendekatan kuantitatif dengan metode deskriptif rekayasa Teknik dengan memanfaatkan tiga fase yaitu pengukuran manual, perhitungan manual dan simulasi Dialux Evo 8.2. Pengukuran manual menggunakan Luxmeter sebagai alat ukur untuk mendapatkan nilai kuat penerangan yang terukur pada ruang baca dan ruang perkuliahan berdasarkan Standar. Perhitungan manual menggunakan cara perhitungan menurut SNI. Simulasi menggunakan Software Dialux Evo 8.2 untuk mengoptimalkan nilai kuat penerangan yang seharusnya digunakan pada ruang baca dan ruang perkuliahan. Hasil penelitian menunjukkan bahwa nilai kuat penerangan yang dihasilkan pada ruang baca dan ruang perkuliahan masih belum memenuhi standar yang ditentukan. Peneliti melakukan 3 skenario desain perbaikan. Desain perbaikan skenario pertama pada ruang baca dan ruang perkuliahan diperoleh rata-rata presentase optimalisasi 72% dan 57%, pada skenario kedua diperoleh presentase optimalisasi 20% s/d 88%, pada skenario ketiga titak lampu ditambah, merubah lampu dan merubah karakter dinding diperoleh presentase optimalisasi sebesar 23% s/d 89%. Maka dapat disimpulkan bahwa skenario dua yang dilakukan untuk pengoptimalisasian didapatkan beberapa hasil kuat penerangan yang sesuai dengan standar yang telah ditetapkan pada ruang baca dan ruang perkuliahan dan nilai simpangan yang dihasilkan antara ruangan yang tidak terkena cahaya matahari dan ruangan yang terkena cahaya matahari memiliki simpangan yang tidak jauh.

Method engineering to increase labor productivity and eliminate downtime

Purpose: The purpose of this work is to present a method based on the application of method engineering, in order to eliminate downtime and improve the manufacturing cell.Design/methodology/approach: The research strategy employed was a case study applied to a manufacturing company to explore the causes of excessive dead time and low productivity. The methodology used was divided in five steps. The first corresponds to the analysis of the lathe and grinding process; the second is the elaboration of the man-machine diagram to identify dead times; the third is the application of the improvement proposal; the fourth is the redistribution of the cell to optimize the process; the fifth is to conclude from the results obtained.Findings: With the proposed method, the downtime was reduced by 41% and only 50% of the available labor is required, therefore, it is concluded that the method can be used to redesign manufacturing cells.Research limitations/implications: This research was limited to analyzing and improving human-machine interaction, since work is not just the machine, or the individual alone, or the individual manipulating the machine, therefore, no other tools were used to improve the time of machines operation.Practical implications: Designing a manufacturing cell that allows the operator to do his job with less fatigue and not adapt the operator to the job, as commonly happens.Social implications: Companies must show a greater interest in occupational health by including human capital in their optimization plans to avoid future harm to workers.Originality/value: The key contribution of this paper focused on developing a novel and practical methodology to design or re-design manufacturing cells to improve productivity considering the human factor, inspired by the main concepts of method engineering.
