Judul: Formulation of Indoor Air Comfort Index for  in The District Kebumen Gymnasium
Abstrak: Kenyamanan pengguna gedung olahraga menjadi faktor yang perlu diperhatikan dalam pembangunan gedung olahraga. Penelitian ini bertujuan menyusun formulasi indeks kenyamanan ruang pada gedung olahraga dengan memperhitungkan kondisi intensitas cahaya, kebisingan, suhu udara ruang, kebauan, dan kelembaban relatif. Metode kuantitatif dan metode kualitatif digunakan pada penelitian ini. Metode kuantitatif didasarkan pada pengukuran lima parameter di gedung olahraga dan metode kualitatif didasarkan pada pengisian kuesioner oleh responden. Formula indeks kenyamanan udara dalam ruang (KUR) diperoleh dari total perkalian antara nilai bobot masing-masing parameter dengan indeksnya. Berdasarkan hasil pengisian kuesioner yang diisi oleh 75 responden diperoleh nilai bobot untuk intensitas cahaya sebesar 0,27, suhu sebesar 0,22, kelembaban relatif sebesar 0,18, kebisingan sebesar 0,17, dan kebauan sebesar 0,16. Pengukuran pada delapan gedung olahraga mendapatkan nilai rata-rata suhu sebesar 28,4 ℃, kebisingan sebesar 65,7 dB(A), kebauan sebesar -0,1, kelembaban relatif sebesar 89,1 %, dan intensitas cahaya sebesar 36,6 lux. Berdasarkan hasil penelitian, kedelapan gedung olahraga di Kabupaten Kebumen berpredikat cukup nyaman dengan nilai indeks KUR 2,1-2,5., In constructing a gymnasium, the comfort of gymnasium users should be a considered factor. This study aims to obtain a spatial comfort index formulation in a gymnasium by considering the conditions of light intensity, noise, temperature, odor, and relative humidity. Quantitative methods and qualitative methods are used in this study. Five parameters measured in the gymnasium are used in the quantitative method. Meanwhile, questionnaires filled by respondents are used in the qualitative method. The equation for indoor air comfort index (KUR) is obtained from the total multiplication between the weight values of each parameter and its index. Based on the filled out questionnaires conducted by 75 respondents, the weight value for light intensity is 0,27, the temperature is 0,22, relative humidity is 0,18, noise is 0,17, and odour is 0,16. Measurements at eight gymnasia obtained an average temperature value of 28,4 ℃, noise of 65,7 dB(A), the odour of -0,1, relative humidity of 89,1 %, and light intensity of 36,6 lux. This study showed that the eight gymnasia in Kebumen Regency were considered quite comfortable with a KUR index value of 2,1-2,5.

Judul: Formulation of Indoor Air Comfort Index for Sukaraja Sub-district Office, Bogor Regency
Abstrak: Faktor yang perlu diperhatikan dalam perancangan dan pembangunan gedung kantor adalah kenyamanan pekerja terhadap gedung tersebut. Penelitian ini dilakukan untuk memformulasikan suatu indeks kenyamanan udara dalam ruang (KUR) dengan mempertimbangkan parameter temperatur, kelembaban relatif, kebisingan, intensitas cahaya, dan kebauan. Pengukuran yang dilakukan yaitu temperatur, tingkat kebisingan dan intensitas cahaya, sedangkan untuk mengukur kesan bau digunakan skala hedonisme kebauan. Pembobotan dilakukan untuk mengetahui tingkat pengaruh dari masing-masing parameter berdasarkan 58 responden. Diperoleh faktor pembobot untuk temperatur 0.28, kelembaban relatif 0.16, kebisingan 0.19, intensitas cahaya 0.22, dan kebauan 0.15. Formula indeks KUR merupakan total perkalian antara indeks masing-masing parameter dan nilai faktor pembobotnya. Indeks KUR ditetapkan lima tingkatan, dari sangat nyaman hingga tidak nyaman. Berdasarkan hasil perhitungan, Ruang Camat dan Ruang Sekretaris Camat mendapatkan indeks KUR 4.1 (sangat nyaman), Ruang Pemerintahan dan Ruang Ekonomi Pembangunan mendapatkan indeks KUR sebesar 3.0 dan Ruang PKK mendapatkan indeks KUR 2.6 (cukup nyaman), serta delapan ruangan lainnya mendapatkan indeks KUR berkisar 3.1-3.8 (nyaman)., The factor that needs to be considered in the design and construction of an office building is worker comfort. This research was conducted to formulate the indoor air comfort index (IAC) by considering the parameters of temperature, relative humidity, noise, light intensity, and odour. Measurements taken are temperature, noise level and light intensity, while to measure odour impression, odour hedonism scale is used. Weighting is carried out to determine the level of influence of each parameter based on 58 respondents. The weighting factors were obtained for temperature 0.28, relative humidity 0.16, noise 0.19, light intensity 0.22, and odour 0.15. The IAC index formula is the total multiplication between the index of each parameter and the weighting factor value. The IAC index is set at five levels, from very comfortable to uncomfortable. Based on the results of the calculation, Sub-district head’s room and Secretary’s room obtained an IAC index of 4.1 (very comfortable), Government’s room and Economic Development’s room obtained an IAC index of 3.0 and PKK room got an IAC index of 2.6 (quite comfortable), and ten other rooms got an IAC index ranging from 3.1-3.8 (comfortable).

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
