Abstract

Kenyamanan audial merupakan salah satu faktor dalam perencanaan bangunan, khususnya bangunan ibadah seperti gereja. Dalam mencapai kenyamanan audial ruang, arsitek hanya mengacu pada standar yang telah direkomendasikan oleh para ahli tanpa mengetahui pendapat dari pengguna ruang tersebut. Tujuan penelitian ini adalah untuk mengevaluasi dan menyajikan saran desain agar kenyamanan audial pada ruang gereja bisa tercapai. Metode penelitian kuantitatif dengan menganalisis data secara statistik-deskriptif. Alat Sound Level Meter digunakan untuk mengetahui distribusi tingkat tekanan bunyi dalam ruang gereja dan bising latar belakang yang dapat mengganggu suasana khidmat gereja. Waktu dengung dihitung dengan rumus Sabine, redesain dilakukan dengan simulasi menggunakan program Autodesk Ecotect Analysis 2011, serta kuesioner diolah dengan menggunakan program IBM SPSS Statistics 25. Hasil penelitian menyimpulkan bahwa distribusi tingkat tekanan bunyi telah merata, sedangkan bising latar belakang dan waktu dengung dalam ruang gereja masih melebihi standar. Namun secara keseluruhan, pengguna telah merasa nyaman dengan kondisi audial ruang gereja tersebut. Selanjutnya, jarak dari sumber bunyi dapat mempengaruhi tingkat tekanan bunyi, kebocoran suara dapat mempengaruhi bising latar belakang, serta penggunaan material dan perabot dapat mempengaruhi nilai waktu dengung ruang. Penelitian ini diharapkan dapat menjadi acuan dalam mendesain gereja selanjutnya atau bangunan sejenisnya.

Abstract

Thermal comfort is always associated with the climatic situation. Thermal comfort, known as a sense of comfort in thethermal situation in the surrounding environment, is also a necessity for space users. Open space is a place for spaceusers who must be able to create a comfortable situation, one of which is thermal comfort. Temperature, humidity, windvelocity, and radiation intensity are elements of the thermal environment, as well as human metabolism and clothinginsulation as human physical and physiological factors, are the six parameters of outdoor thermal comfort levelaccording to ASHRAE Standard. This research is a type of descriptive research that aims to explain the thermalconditions felt by the perpetrators of activities in one of the open spaces in the Soppeng Regency, the Ompo LakeTourism Area. The results obtained were from 349 respondents and as many as 216 respondents felt comfortable in themost comfortable temperature conditions in the range of 27.1 - 31˚C, with humidity > 70%, wind velocity 0.2 – 0.5 m/s,and radiation intensity <150 W/m2. Activity with a relaxed sitting (1 met) and moderate tropical clothes (0.3 – 0.5 clo).

Abstract

the potential to be a composite reinforcement and increase sound absorption through the Chemical Pulping process. This study aims to investigate the alleged influence of the use of matrix type on the strength of sound absorption in chicken feather fiber composites. The research method used is experimental research with the manufacture of composite specimens that vary the volume fraction of composite fibers with various types of matrices. Sound absorption testing using impedance tubes. Data analysis techniques in this study use descriptive data analysis. The results of this test show the effect of using matrix type on increasing the absorption coefficient of SBA composites. The maximum absorption coefficient is found in the SBA-K composite (Chicken Feathers – Kanji).
