Judul: Indeks Kenyamanan dan Tingkat Konsumsi Energi Listrik di Rumah Sakit Azra, Bogor
Abstrak: Indoor air comfort is affected by temperature, relative humidity, lighting, and noise. This study aimed to determine comfort index and its relationship with electrical energy consumption at Azra Hospital, Bogor. Measurement was done in rooms which represented different function or units. The temperature and RH measurement were conducted using thermometer (dry and wet bulb) and psychrometric chart. Light intensity measurement refers to SNI 16-7062-2004 about Light Instensity Measurement at Workplace whereas noise level measurement refers to KEP-48/MENLH/11/1996 about Noise Level Standard. Another related regulation is Kep. Men. Kes. RI No. 1204/MENKES/SK/X/2004 about Health Regulation of Hospital Environment. The result of study shows that only dental clinic and High Care Unit (HCU) that complies with regulation, meanwhile according Temperature Humidity Index there are 23 rooms that can be classified in comfort category. The rooms that has light intensity complied with regulations are CT Scan, radiology, kitchen, and lobby toilet. The rooms that has noise level complied with regulation are kitchen, laundry, and dental clinic. Electrical energy consumption for air conditioning of four different care rooms is 7.32 kW. Energy management should be improved at rooms that does’t comply with regulations.

Judul: Penentuan Indeks Kenyamanan Udara dalam Ruang Berdasarkan Temperatur, Kelembaban Relatif, Kebisingan, Kebauan dan Intensitas Cahaya
Abstrak: Beberapa penelitian menunjukkan bahwa bekerja dengan kondisi lingkungan yang baik akan meningkatkan produktivitas. Penelitian ini dilakukan untuk memformulasikan suatu indeks kenyamanan udara dalam ruang dengan mempertimbangkan kondisi temperatur, kelembaban relatif, kebisingan, kebauan, dan juga intensitas cahaya. Penelitian ini dilakukan dengan metode kualitatif dan kuantitatif. Pengukuran yang dilakukan antara lain: pengukuran temperatur, pengukuran tingkat kebisingan dan pengukuran intensitas cahaya, sedangkan untuk mengukur kesan bau digunakan skala hedonisme kebauan. Pembobotan dilakukan untuk mengetahui tingkat pengaruh dari masing-masing parameter berdasarkan 117 responden, dan diperoleh faktor pembobot sebesar 0.28 untuk temperatur, 0.16 untuk kelembaban relatif dan kebisingan, serta 0.20 untuk intensitas cahaya dan kebauan. Indeks kenyamanan udara dalam ruang ditetapkan 5 tingkatan, yakni tidak nyaman (1), kurang nyaman (2), cukup nyaman (3), nyaman (4), dan sangat nyaman (5). Berdasarkan hasil perhitungan, Lab. Lingkungan, ruang kuliah dan asrama mendapatkan indeks kenyamanan udara dalam ruang berkisar 2.3-2.9 (kurang nyaman), sedangkan Lab. Komputer sebesar 3.0 (cukup nyaman), serta UPT FATETA sebesar 3.4 (cukup nyaman).

Judul: Penyusunan Overlap Graph menggunakan Suffix Tree pada DNA Sequence
Abstrak: The DNA sequence assembly is very important in genome analysis. This step aims to reconstruct contigous DNA fragment (contigs) from short fragment by concatenating fragments based on the overlap region among them. This method employs overlap graph for solving the problems. In this graph, nodes represent fragments and edges represent overlap. This research developed a software for constructing overlap graph using suffix tree. The evaluation was conducted by measuring the number of nodes, number of edges, and the execution time in many values of minimum overlap. The minimum overlap is defined as the minimum length of substring which is considered as the overlap region between two fragments. The evaluation results showed that the number of nodes, the number of edges, and the execution time were increased with the decreasing of the minimum overlap value.
