Abstract

Optimum conditions help us think and work better. Thermal comfort in lecture buildings is important to maintain students’s comfort and help them concentrate on study. The fastest way to achieve expected thermal comfort inside the lecture room is using air conditioner, however, compensation on high electricity bills and degradation of the environmental quality has to be made. Therefore, the aim of this paper is to find and promote several environmental friendly strategies which can provide comfort to users in one hand, but also can reduce energy consumption in another hand. There have been several strategies in records to increase thermal comfort in buildings. To select the best and the most appropriate alternative, Analytical Hierarchy Process method was used by setting the criteria, sub-criteria, and alternatives to increase thermal comfort in lecture buildings of Andalas University. To test the selected alternative, thermal comfort inside two lecture rooms were evaluated experimentally. The comfort level was evaluated using PMV (Predicted Mean Vote) and PPD (Predicted Percentage Dissatisfied) model. For all experimental conditions, PMV and PPD results and individual thermal vote results showed a good match statistically meaning that the PMV and PPD models could predict thermal condition inside the lecture rooms. Results also showed that the presence of natural vegetation infront of glass windows of the lecture rooms statistically improved thermal comfort sensations of students under natural ventilation mode and reduced thermostat setting under air conditioning mode.

Abstract

Nowadays, developers of residential houses often neglect to pay attention about the air circulation as one of the factors that affects thermal comfort zones inside the room environment. In general, people overcome the thermal discomfort using mechanical ventilation such as a fan or Air Conditioning (AC).This study measured the comfort zone of 32 row houses in the Batam city with two types of floor area (LT ≤ 36 m2 and LT > 36 m2). Other variables include Ceiling Height (Tpi), Aperture Area (Vi), Wall Materials (Bhi) and Orientation (Ori) were also considered in this measurement. The results show that thermal comfort zone was influenced by the wall material (Bh1) made from brick, aperture area (V2) > 20% of the floor area, and ceiling height (Tp2) > 3 m. While the house orientation variable can still be received by utilizing the architecture techniques to reduce direct solar radiation. This study also formulated three models of row house design with ergo-ecological concept, which are Ree = f {Lti, Bh, V, Tp2, Ori} atau Ree = f {Lt2, Bh, V, Tp1, Or2} atau Ree = f {Lt1, Bh, V, Tp1, Or1}.

Abstract

PT. X is one of the companies located in Dumai Industrial Region, produces fertilizer. This company has three production plants. The production capacity of the first plant is 450 tons/day, the second plant produces 750 tons/day and the third plant produces 700 tons/day. PT. X is supported by 2 sub companies, they are PT. A and PT. B. PT. A operates 5 bagging lines and PT. B operates 3 bagging lines. The fertilizer bagging process has three steps where each step has its own work station: putting the labeled sack to the hook followed by filling the sack with fertilizer, installing the tie cable, and sewing the fertilizer filled sack. From the initial survey, it was found that the processing time is not optimal to reach production target. PT. A and B have to set 24 working hours per day to run the target resulting on frequent over time, excessive fatigue and the negative impact of physically and mentally for the workers. Author’s hypothesis is the current condition has been one of the reasons for a decline of the production output. Therefore, the purposes of the research are to find the impact of current working hours and shift work pattern on the physical and psychological response of the workers and to calculate the standard time required to complete one cycle of bagging process. This standard time is very crucial to determine production target thus determine the optimal working hours and shift rotation. Measuring of heart rate are collecting results of a questionnaire of NASA-TLX are the parameters used to evaluate the physical and psychological response of workers. Two workers from different group worker, different shift work, from PT. A and PT. B were selected as samples to evaluate their heart rate pattern. The questioner spread out to all workers. Time standard was determined by observing and taking data of 40 bagging cycles for each shift work. The results show that shift work affecting the physiological response of workers in PT. B in the category between moderate to extreme especially for working element of arranging fertilizer sack to the pallet. This result was found for the two group workers. Frequent short rests between times are required to provide quick recovery for the workers and reduce excessive fatigue. Average standard time complete one bagging cycle was 0.12 minutes and 0.13 minutes for PT. A and PT. B, respectively. These standard times can be used to set the production output target for the two companies. Last, short rotation shift work with an additional number of workers is recommended for the shift pattern

Abstract

This research aims to determine thermal conditions and sensation of thermal comfort in classrooms of high schools in Padang. This study was conducted in 11 State Senior High School (SMA) represented 11 districts in Padang. About 10% of total student body in each schools were participated in this study to vote thermal comfort questioners. To determine thermal comfort level in this study, PMV (Predicted mean Vote) and PPD (Predicted Percentage of dissatisfied) method were used according to standard of thermal comfort in ASHRAE 55-2005 and ISO 7730. PMV method is used to determine scope of situation in the environment that scaled from +3 for very hot until -3 for very cold, and PPD is a method to calculate the number of human (in percentage) dissatisfied with the environment. Calculated PMV and PPD were compared with PMV and PPD resulted from individual vote from questionnaires. Result showed that in general, thermal conditions in classrooms had air temperature and radiant temperature from 27oC – 30oC, air humidity from 68% - 80%, and wind speed of 0 m/s. Calculated PMV from this condition were ranging from +1 slightly warm) until +2 (warm) while PPD calculated greater than 20%. Compared with calculated PMV and PPD values, the individual vote showed values from +0,5 (neutral) until +1 (slightly warm) while PPD values of individual vote greater than 20% except for SMA 2 and SMA 11 Padang. It is concluded that improvements of indoor thermal conditions have to make inside classrooms as well as landscape outside in order to improve thermal comfort level of students during learning and teaching.

Abstract

Industri makanan olahan Indonesia, khususnya UMKM, berkembang pesat seiring meningkatnya permintaan rendang sebagai produk khas Sumatera Barat yang berpotensi ekspor, namun partisipasi UMKM dalam perdagangan internasional masih rendah akibat kompleksitas standar dan persyaratan ekspor. Penelitian ini bertujuan merumuskan strategi pemenuhan standar dan persyaratan ekspor bagi UMKM rendang di Sumatera Barat dengan menggunakan data hasil wawancara pelaku UMKM eksportir, instansi pendukung ekspor, analisis regulasi, serta kuesioner terbuka yang dianalisis menggunakan pendekatan Grounded Theory, yang terdiri atas tahapan open coding untuk identifikasi tema, axial coding untuk menghubungkan kategori dan subkategori, serta selective coding untuk merumuskan kategori inti sebagai dasar penyusunan strategi pemenuhan standar dan persyaratan ekspor. Hasil penelitian menunjukkan bahwa hambatan yang dihadapi oleh UMKM rendang dalam memenuhi standar dan persyaratan ekspor bersumber dari lima kategori utama, yaitu kurangnya pendampingan dan sosialisasi, kompleksitas dokumen dan teknis, keterbatasan infrastruktur dan peralatan, tantangan teknis produksi dan higienitas, serta hambatan finansial. Kondisi ini membentuk suatu rantai hambatan sistemik yang saling memperkuat dan mempersulit kesiapan ekspor pelaku usaha kecil. Strategi yang dirancang untuk menjawab permasalahan tersebut mencakup lima pendekatan utama, yaitu peningkatan pendampingan dan sosialisasi regulasi ekspor, pemenuhan infrastruktur dan alat produksi sesuai standar, pengurangan beban biaya sertifikasi dan pengujian melalui kolaborasi lintas lembaga, peningkatan kemampuan teknis dan dokumentasi ekspor, serta standarisasi proses produksi dan praktik higienitas. Validasi oleh para ahli menunjukkan bahwa meskipun sebagian strategi telah dijalankan oleh instansi terkait, implementasinya belum terstruktur secara berkelanjutan dan belum menjangkau seluruh UMKM.
