Indonesia merupakan negara beriklim tropis dengan temperatur dan kelembaban yang tinggi di beberapa kota termasuk di Timika. Hal ini menyebabkan kondisi termal yang tidak nyaman serta penggunaan standar kenyamanan ruang yang ada sering berbeda dengan persepsi penghuni sehingga mengakibatkan pemborosan energi pendingin ruang.Penelitian ini bertujuan: (1) mengetahui kenyamanan termal adaptif pada penghuni rumah tinggal sederhana berventilasi alami di kota Timika, yakni kenetralan, keberterimaan dan preferensi termal penghuni, dan (2) mengetahui perilaku adaptif penghuni dalam pencapaian kenyamanan termal individu. Penelitian ini dilaksanakan di salah satu rumah tinggal berventilasi alami pada salah satu perumahan di daerah urban dan suburban di kota Timika. Digunakan pengukuran empat parameter lingkungan, yakni suhu, kelembaban, kecepatan udara, dan mean radiant temperature (MRT).Data diperoleh melalui pengisian kuesioner kepada seratus responden di daerah urban dan suburban.Data kenetralan termal dianalisis dengan analisis regresi menggunakan software SPSS 19, sedangkan keberterimaan dan preferensi termal serta perilaku adaptif dianalisis berdasarkan hasil dari jawaban kuesioner. Hasil penelitian menunjukkan bahwa kenetralan termal yang tinggi, yaitu 30.560C Top pada daerah urban dan 30.170C Toppada daerah suburban. Lebih dari 90% responden dapat menerima kondisi termal setempat.Akan tetapi, lebih dari 50% menginginkan kondisi termal menjadi lebih sejuk.Perilaku yang paling sering dilakukan responden dalam mencapai kenyamanan termal individu, yakni menyalakan kipas angin.

Shopping centers construction have to do a good building management so it would have a comfort for visitors. One of comfort things that should get the attention is audial comfort. In Gorontalo City, Most of the electricity users choose to use electricity from Generator set supply, this results an increase in noise. The rotors of the electrical generators basically can be controlled by the use of box silent that has been specially designed so that it can prevent noise. In addition on the control of noise to the same type of chambers electrical generators may also be convened with arranging in layer interior of the same type of chambers with the material acoustic absorbed sound. The use of acoustic material sound-absorbent can work effectively with right material, in accordance with the degree of hardness sound taking place in the room. This research takes the generator chamber in one of shopping centers in Gorontalo. Generator chamber in this study has been tasted in two treatment tests of space generator. In first test, the wall of the coated material dampers from Styrofoam with thickness 2 cm, and obtained percent reduction noise of 8,32 % , While in the second test by using layers Styrofoam and rugs are able to reduce noise into 17,58 %. The final result of the research found is that the previous noise of 95db can be reduced to 78,3db.

To get good quality learning, a comfortable study room is needed both visually, audally and thermally. Thermal comfort is greatly influenced by the climatic conditions of a region. In areas with high daily air temperature, high humidity and low air velocity, it is difficult to produce thermal comfort with natural air conditioning. Jayapura City is one of the cities in Indonesia with daily air temperature and high humidity and low air velocity. Therefore, adaptive processes are needed to achieve thermal comfort in spaces, including study rooms. Each human's adaptive thermal comfort is different according to local climatic conditions. The purpose of this study was to determine the adaptive thermal comfort of students in naturally ventilated classrooms at the Jayapura University of Science and Technology (USTJ) in the city of Jayapura, Papua, namely students 'neutrality, acceptance and thermal preferences, as well as students' adaptive behavior in achieving thermal comfort. This research was conducted in one of USTJ's classrooms in Jayapura, Papua. Four environmental parameters were measured, namely temperature, humidity, wind speed, and mean radiant temperature (MRT). The data were obtained through filling out a questionnaire to 100 USTJ students during the space measurement. Thermal neutrality data were analyzed using regression analysis using SPSS software, while thermal acceptance and preference and adaptive behavior were analyzed based on the results of the questionnaire answers. The results showed that USTJ students' thermal neutrality was at 29.°C Ta or 29.55°C Top. all students can accept the thermal conditions of the room, but 59% of students choose to want the room to be cooler due to their thermal preferences. The adaptive behavior that is carried out is turning on the fan, picking up objects to be used as a fan, leaving the room and drinking more often.

Kenyamanan termal suatu ruang kuliah diperlukan untuk mendukung proses penerimaan pembelajaran oleh mahasiswa. Penelitian ini bertujuan untuk mengetahui kenyamanan lingkungan termal pada ruang kuliah (C4) Fakultas Teknik Universitas Ichsan Gorontalo dengan menggunakan sistem penghawaan buatan (AC). Kuisioner dibagikan kepada 30 mahasiswa Teknik Arsitektur dengan menggunakan sensasi termal ASHRAE, penerimaan kondisi termal serta preferensi termal. Bersamaan dengan itu dilakukan pengukuran lapangan untuk mengetahui temperatur udara (Ta), kelembaban relatif (RH), Mean Radiant Temperature (MRT) dan kecepatan udara (Va). Hasil penelitian menunjukkan bahwa 50% mahasiswa memilih agak dingin pada sensasi termalnya sedangkan 97% dapat menerima keadaan termal ruang, dan hampir 70% mahasiswa tidak menginginkan perubahan kondisi termal pada ruangan tersebut.
