Studi Distribusi Udara Pada Ruang Ber-AC Untuk Mencapai Tingkat Efisiensi Energi yang Optimal

Penggunaan energi listrik bangunan di Indonesia didominasi oleh pemenuhan kebutuhan AC. Salah satu upaya untuk mengoptimalkan kinerja AC adalah dengan memperhatikan pola distribusi aliran udaranya. Saat ini, di pasaran terdapat 3 tipe pola distribusi udara AC, yaitu (1) perfect mixing, (2) displacement, dan (3) radiant cooling. Penelitian ini menguji pengaruh tipe-tipe distribusi AC tersebut terhadap konsumsi energi pendinginan dengan metode studi literatur, perhitungan matematis, dan simulasi komputer. Adapun kriteria kenyamanan yang digunakan bersumber dari SNI 03-6572-2001 dengan besaran suhu udara 24oC sebagai titik tuju (setpoint) AC dari kondisi awalnya 28,1oC. Sedangkan perhitungan tingkat konsumsi energi didapatkan dari lamanya waktu mencapai setpoint. Perhitungan menggunakan skema tiga skenario beban kalor diasumsikan menjadi lamanya waktu mesin AC saat jeda (idle), yaitu; (a) beban kalor besar, waktu jeda 30 detik, (b) beban kalor sedang, 60 detik, dan (c) beban kalor kecil, 90 detik. Dengan waktu operasional 300 jam per bulan, hasil perhitungan konsumsi energi pola displacement sesuai skenario adalah; (a) 148,4 kWh/bulan, (b) 116,6 kWh/bulan, dan (c) 96 kWh/bulan. Sedangkan perfect mixing; (a) 160,9 kWh/bulan, (b) 132,8 kWh/bulan, dan (c) 113,1 kWh/bulan, serta radiant cooling; (a) 191,5 kWh/bulan, (b) 180,5 kWh/bulan, dan (c) 170,6 kWh/bulan.Kata kunci: efisiensi energi, pengkondisian udara, pola distribusi udara

KINERJA STRUKTURAL INTERLOCKING COMPRESSED EARTH BLOCK (ICEB) DENGAN SERAT IJUK SEBAGAI STABILISATOR

Bahan bangunan berbentuk blok modular sudah cukup dikenal di dunia rancang bangun lingkungan binaan di Indonesia. Dalam bentuknya yang paling sederhana, blok modular ini dikenal dengan nama bata, bata merah, batako, conblock, atau lainnya. Unitnya yang modular memberi kemudahan dalam pembuatan, aplikasi dan transportasinya. Kekurangannya, blok ini umumnya dibuat melalui proses yang boros energi dan polutif (pembakaran bata, pemanasan semen dan kapur di tanur / kiln). Dalam perspektif lingkungan binaan yang berkelanjutan dan ramah lingkungan, kekurangan ini perlu diperbaiki agar jejak karbon habitasi manusia dapat ditekan. Tantangannya adalah mendapatkan blok modular yang hemat energi, tetapi dapat mencapai stabilitas dan performa struktural yang sesuai standard. Dalam penelitian ini, benda uji berbahan tanah dibuat dengan tanpa melalui proses pembakaran atau pemakaian semen dan kapur. Serat ijuk digunakan sebagai pengganti semen dan kapur yang selama ini dikenal sebagai stabilisator pilihan dalam pembuatan blok modular. Untuk melihat kinerja strukturalnya, benda uji utama dan pembandingnya diuji pada mesin uji tekan (compressive testing machine). Pengujian dilakukan dengan menggunakan benda uji pembanding berupa blok modular dengan bentuk, dimensi dan cara pembuatan yang serupa, dengan perbedaan pada komposisi bahannya. Sebagai rujukan, digunakan SNI 15-2094-2000 (Indonesia) dan IS 1077 : 1992 (India) tentang klasifikasi kuat tekan bata merah bakar.

Ruang publik merupakan ruang untuk melakukan kegiatan sosial, ekonomi, dan budaya. Selain ruang terbuka hijau, ruang sepanjang sungai juga mempunyai potensi untuk dijadikan sebagai sebagai ruang publik. Faktanya ruang sepanjang sungai hanya digunakan untuk permukiman liar dan tidak ada penyediaan ruang publik di dalamnya. Penelitian akan berfokus pada penentuan kriteria yang dibutuhkan untuk membentuk ruang publik di sekitar bantaran sungai dalam mendukung aksesibiltas dan peningkatan aktivitas. Teori yang akan digunakan ialah prinsip kawasan terintegrasi sungai (Charles A. McLaren - A Guide to Riverfront Development) dan teori Public Space oleh Stephen Carr dan Carmona. Tapak yang akan di analisis adalah ruang publik di Kawasan Kalijodo yang berbatasan langsung dengan air. Berdasarkan kedua teori yang digabungkan, kriteria yang akan digunakan dalam menganalisis objek studi adalah kenyamanan, aktivitas, sosiabilitas dan yang ditekankan ialah akses, meliputi titik akses pedestrian, tipe dan distribusi akses universal, dan prioritas pedestrian. Berdasarkan penelitian dapat disimpulkan akses secara fisikal sudah terpenuhi dengan adanya tangga dan jembatan penghubung dari sungai, namun harus mempertimbangkan akses secara visual, menambahkan program yang spesifik agar pemetaan merata dan ditunjang dengan vegetasi yang lebih rapat untuk mendukung kenyamanan.Kata kunci: aktivitas, aksesibilitas, ruang publik, bantaran sungai Title: Relation of Activity and Connectivity of Kalijodo as a Public Space Public space is a place for social, economic and culture activity.

KONSEP EKOLOGIS DAN BUDAYA PADA PERANCANGAN HUNIAN PASKA BENCANA DI YOGYAKARTA

Hunian bantuan pasca bencana biasanya didesain dengan desain yang hanya mempertimbangkan kecepatan konstruksi dan efisiensi biaya pembangunan dengan kurang mempertimbangkan kekhasan budaya lokal serta kondisi lingkungan suatu kawasan. Bila hal ini terjadi secara terus menerus, maka arsitektur lokal yang merupakan wadah dari budaya lokal dan bentuk respon masyarakat terhadap kondisi lingkungan sekitar secara perlahan akan terancam hilang bersamaan dengan adanya bencana, yang kemudian akan tergantikan dengan bentuk-bentuk hunian yang hampir seragam disemua tempat. Penelitian ini bertujuan untuk mengidentifikasi konsep ekologis dan budaya pada perancangan hunian paska bencana di desa Ngibikan yang berhasil menjawab kebutuhan penghuninya dan menyatu dengan kehidupan masyarakatnya. Metode yang digunakan adalah metode kualitatif deskriptif untuk menggali konsep ekologi dan budaya pada perancangan di desa Ngibikan.Berdasar hasil penelitian didapatkan bahwa penerapan konsep ekologis dan budaya pada perencanaan desain hunian paska bencana di desa Ngibikan turut mempengaruhi keberhasilan desain dalam menjawab kebutuhan penghuni dan merespon kondisi alamnya. Diharapkan proses rekonstruksi pemukiman paska bencana di desa Ngibikan ini dapat menjadi contoh bagi proses rekonstruksi dimasa mendatang agar proses rekonstruksi tidak hanya berupa upaya memenuhi kebutuhan hunian bagi korban bencana namun juga suatu upaya melestarikan arsitektur lokal yang merupakan wadah dari budaya lokal dan bentuk respon masyarakat terhadap kondisi lingkungan di suatu kawasan.Kata kunci: hunian, paska bencana, rekonstruksi, ekologis, budaya lokal Title: Ecologicals and Culture Concepts in Post-Disasters Housing Design Post-disaster housing is usually designed with a design that considers only the rapidity of development and cost efficiency without thinking of local cultural and environmental conditions of an area. If this happens continuously, then the local architecture which is a container of local culture and the form of community response to the surrounding environment will slowly be threatened to disappear along with the disaster, which will then be replaced by almost uniform shelter in all places. This study aims to identify ecological and cultural concepts on post-disaster residential design in Ngibikan village that successfully responds to the needs of its inhabitants and blends with the lives of its people. The method used is descriptive qualitative method to explore the concept of ecology and culture on the design in Ngibikan village. Based on the results of the research, it is found that the application of ecological and cultural concepts in the design of post-disaster residential design in Ngibikan village also influenced the success of the design in responding to the needs of the residents and responding to the natural conditions. It is expected that the post-disaster reconstruction process in Ngibikan village can serve as an example for the reconstruction process in the future so that the reconstruction process will not only be an effort to fulfill residential needs for disaster victims but also an effort to preserve local architecture which is a container of local culture and form of community response to the condition environment in an area. Keywords: housing, post-disaster, reconstruction, ecological, local cultural
