The Relation Between Temperature and Time on the Application of Coconut Fiber Cement Panels as Potential for Wall Cover

This research is about coconut fiber material which has the potential to wall cover and the relationship between temperature and time of coconut fiber material in reducing temperature. The wall, as one of the building envelopes, endures high sun radiation. It needs the wall material that can reduce temperature to ensure thermal comfort inside the building. Gaining building thermal comfort requires architecture, knowledge, and skills as well as innovation.  Lowering temperature in the room can be done through wall modifications so that it can lessen the use of air-con. Thus, research on the use of natural materials such as coconut fiber for walls is needed. This study is using an experimental approach.  The coconut fiber was tested to measure the temperature reduction and study its linear equations from the relation between temperature and time given. The analysis is comparing two materials: (1) the mix of cement and sand without coconut fiber; (2) The mix of cement and coconut fiber material. The tests’ procedures are applying heat temperature to the side of the material and measuring the resulting absorbed temperature on the other side of both materials.  Both of the material were exposed to 35°C heat temperature for 150 minutes. The materials are set in a box. The tests use 3 thermal sensors are T1, T2 and T3 and one heater. This heater is connected to the power source and a device to control the temperature given called Ts controller. The test shows different results between the temperature of material with coconut fiber and material without coconut fiber. The coconut fiber material has a lower temperature than that of without coconut fiber. The linear equation of the coconut fiber material related to the time and temperature shows the longer time, the lower the temperature is. Thus, it indicates the potential of coconut fiber material used as cover for building walls

Behavioral Architecture Approach to Concept of Housing for the Face of Pandemic

One effect caused by a calamity is the psychological impact on the community. In December 2019 covid-19 viral infected many countries including Indonesia which later changed his status to make cause serious problems because there is no vaccine to prevent transmission of the virus. This condition requires every society to comply with government regulations as quarantine, PSBB, WFH, social distancing. The psychological impact that is often found in society is afraid of panic and other stress. Psychology is closely related to conducting this study will discuss architectural behavior that plays a role in the relationship between people and space. This research as if would explain what occurred in behavior and how your family made the architect can solve this problem by emphasizing psychiatric problems through the application for building design, occupancy of a room. The theory of architecture as a guide in determining objects for the attention that the occupants need through analysis of the type of activity and used before and during the pandemic. This approach asserts the need to understand the behavior and needs of the people living in the house in use. This research activity was carried out with space objects selected based on the similarity of form and design of the average home in Medan City. In activities, the research was conducted with a sample housing path in our name in “Villa Nusa Sempurna” with different types of houses, and various characters users and primary focus will also be on the type of house that is most in demand are in residential. Is a type of type 70 most interested in shape and arrangement with the most commonly found in residential of the town. The result of this research is designed products have been analyzed based on the assessment of behavior so that it can become a new alternative designing safe and comfortable housing for the face of a pandemic

EVALUASI BANJIR RANCANGAN DAS DELI DENGAN METODE HSS GAMA 1 DAN HSS SCS

Sungai Deli adalah salah satu sungai di propinsi Sumatera Utara, memiliki panjang 47 km dan luas DAS sebesar 402 km2. Sungai Deli ini tidak luput dari masalah banjir yang pada akhirnya dapat menyebabkan banyak kerusakan. Perencanaan pengendalian banjir, pengamanan sungai dan berbagai bangunan air di sungai Deli perlu dilakukan analisis hidrologi untuk mendapatkan besaran banjir rencana. Penelitian ini bertujuan untuk memperoleh besaran debit banjir rencana dan membandingkan debit banjir agar memperoleh perbandingan debit banjir rencana. Dalam penelitian ini digunakan metode Hidrograf Satuan Sintetik Gama I. Hasil perhitungan didapat debit banjir rencana HSS Gama 1 Periode ulang 2, 5, 10, 25, 50, 100 tahun adalah 151, 251, 347, 514, 679, 889 m3/det. Sedangkan HSS SCS Periode ulang 2, 5, 10, 25, 50, 100 tahun adalah 89, 149, 205, 304, 402, 526 m3/det. Perbandingan metode HSS Gama 1 dan metode HSS SCS adalah 1 : 1,69.Manfaat evaluasi banjir dapat memberikan informasi tentang penggunaan metode HSS Gama 1 dan HSS SCS dalam analisis banjir rancangan di DAS Del

MITIGASI BANJIR PADA SISTEM DRAINASE

Sistem Jaringan Drainase Mayor  umumnya dipakai dengan periode ulang antara 5 sampai 10  tahun sedang kan system jaringan Mikro Pada umumnya drainase mikro ini direncanakan untuk hujan dengan periode ulang 2, 5 atau 10 tahun tergantung pada tata guna lahan yang ada.Beberapa daerah diantaranya Kecamatan Medan Polonia, Medan Sunggal, Medan Petisah, Medan Tembung, Medan Barat, Medan Timur selalu terjadi banjir karena draina setidak mampu menampung lagi. Mengingat begitu banyaknya kerugian yang ditimbulkan oleh banjir atau genangan luas dan tinggi, maka penelitian berjudul “Mitigasi Banjir Pada Sistem Drainase” dengan tujuan untuk mengetahui penyebab debit banjir dari besaran hujan. Data yang digunakan data curah hujan dari BMKG selama 10 tahun, untuk menganalisa hidrologi menggunakan Metode Log Pearson III dan Analisa hidrolika menggunakan debit banjir. Mencari hujan rencana dengan kala ulang 2 tahun, 5 tahun, 10 tahun. Kemudian hasilnya dibuat dalam bentuk kurva. Selanjutnya perhitungan debit banjir periodic menggunakan Metode Rasional untuk research. Hasil yang ditargetkan dengan adanya karyai lmiah ini dapat digunakan oleh instansi yang bersangkutan.   metode log pearson type  III Intensitas curah hujan untuk periode ulang ulang 2 tahun adalah 83,83 mm/jam dan debit banjir rancangan untuk Q 2 Tahun adalah 2,885 m3/det. Hasil penelitian ini diharapkan dapat mengurangi risiko banjir
