Fire is one of the hazards that may affect urban areas with high density settlements. Thus, research on fire mitigation is important to be conducted. This paper examines the behavior and preparedness of occupants in high density settlements towards fire risks in urban area. The case study is located at Kelurahan Sukahaji, Kecamatan Babakan Ciparay, Bandung that has very high density settlement as well as prone to fire hazards. This study assess 232 respondents in the study areas on information related to demography, understanding about fire, behavior and preparedness. The respondents understanding on the types of fire sources are still low. Similarly, the behavior related to the activites using fire are still dangerous because some activities are conducted with other activities which make people less aware of the fire hazards. Nevertheless, their knowledge on how to extinguish fires are quite good. This paper recommends more trainings on knowledge of fire source and behavior to be conducted to occupants living in high density settlements in order to reduce fire disaster risk.

Selo, a small agricultural-based village in Boyolali, Central-Java, Indonesia has initiated small-scale rural biogas adoption as it presumably reduces the consumption of LPG, firewood, chemical fertilizer and (womenâs) overall workload, which especially suitable due to the relatively high use of cattle in that area As environmental problems such as global warming from fossil fuel consumption and land degradation from deforestation and overuse of chemical fertilizers, and socio-economic problems as gender empowerment and self-sufficiency are becoming more pressing, it is useful to analyse the benefits of biogas as an alternative renewable energy technology (RET) provision in rural areas. This paper aims to assess the benefits of rural biogas adoption from an economic perspective, through calculating the direct and indirect benefits obtained from biogas adoption in Selo. For this, a field survey was carried out in Selo to ask questions to biogas users (N=21) and non-users (N=5) on their energy and fertilizer consumption, as well as emissions reductions resulting from biogas adoption. Based on the analysis, oon average, a household with biogas saves 490 kWh monthâ1, 20,000 IDR monthâ1,185 kg CO2e monthâ1.Chemical fertilizer consumption remains remarkably high, which may due to a lack of awareness on the potential of digester slurry by the farmers, for indeed, reduction of chemical fertilizer use would help address some environmental problems. Biogas quality of one household has also been determined by comparing its heating value to that of methane; the methane percentage (MP) was approximately 31%. The quality is considerably lower than expected from the literature (i.e. around 60%), which may be due to the farmers neither mixing nor supplying water to the dung. Trainings providing methods for improving digester overall effectiveness to particularly the women-folk may enhance digester management and thus biogas production, as they form the main primary operatives. Despite the room for improvement, the existing results clearly show that biogas adoption significantly reduces greenhouse gas (GHG) emissions, household energy costs, workload, improves environmental conditions and generates income through carbon credit exchange. Therefore, under the notions of sustainable development, environmental preservation and self-sufficiency, policy makers and NGOs should expedite their support in biogas development, e.g. by providing subsidies and awareness raising.

Population living in highly densed settlements in urban area is considered vulnerable to earthquake risk due to limited space exists in the area. To reduce population risks to aftershock earthquake in highly dense settlements, this paper applied simple simulation based on supply-demand concepts in order to understand carrying capacity of current open space for people to evacuate. The case study takes place in one of the most densed populated areas in Bandung City under aftershock earthquake.. The research integrates multi-sources of data: sattelite image, building footprint and GPS field survey to produce detailed landuse. The results show that open spaces that exist in the study area is not able to contain all residents when an aftershock occurs. Finally, this paper recommends some strategies that are necessary to reduce the risks in highly densed urban areas.

Abstract. This study was aimed at evaluating the pedestrian environment walkability from a residential area to a commercial area in Amherst, New York. An audit tool to record data of physical built environment elements was developed and tested. Data collection is integrated taking advantage of geo-spatial technology, so that pedestrian environment characteristics can be presented spatially. In this study, the Pedestrian Environmental Data Scan (PEDS) instrument was adopted to evaluate walkability in pedestrian environments. Thirteen variables were adopted to be used in this study: (1) segment type; (2) land use in the given segment; (3) slope; (4) segment intersection; (5) types of pedestrian facilities; (6) path condition; (7) number of trees shading walking areas; (8) crosswalks; (9) roadway/path lighting; (10) segment attractiveness for walking; (11) segment attractiveness for cycling; (12) segment safety for walking; and (13) segment safety for cycling. To collect and examine the data, the study integrated the audit tool with ArcGIS Online developed by ESRI. Overall, the selected road segments have the characteristics of a walkable environment between a residential area and a commercial area. The most convenient pedestrian environment was identified within the residential area because the sidewalks are attractive, are built on flat slopes, planted with dense shade trees, and have low-volume traffic. In the commercial area, the pedestrian environment is less attractive due to a lack of trees and less safety due to the mixed use of pedestrian pathways for store entrance. The results reflect the need for improvement of the audit tool in future studies.Keywords. walkability, GIS, environment audit, residential, commercial.Abstrak. Penelitian ini bertujuan untuk mengevaluasi pejalan kaki lingkungan pejalan kaki dari daerah pemukiman ke daerah komersial di Amherst, New York. Alat audit telah dikembangkan dan diuji untuk mencatat data unsur lingkungan fisik. Pengumpulan data terintegrasi dengan keuntungan teknologi geo-spasial untuk mengelola analisis, sehingga karakteristik lingkungan pejalan kaki akan disajikan secara spasial. Dalam studi ini, instrumen PEDS (The Pedestrian Environmental Data Scan) diadopsi untuk mengevaluasi walkability di lingkungan pejalan kaki. Tiga belas variabel diadopsi dari PEDS yang akan digunakan dalam penelitian ini, sebagai berikut 1) jenis segmen; 2) penggunaan lahan di segmen tertentu; 3) kemiringan lereng; 4) segmen persimpangan; 5) jenis fasilitas pejalan kaki; 6) kondisi jalan; 7) jumlah pohon yang menaungi area jalan; 8) penyeberangan; 9) penerangan jalan / jalan; 10) daya tarik segmen untuk berjalan; 11) daya tarik segmen untuk bersepeda; 12) keamanan segmen untuk berjalan; dan 13) keamanan segmen untuk bersepeda. Untuk mengumpulkan dan memeriksa data, studi ini mengintegrasikan alat audit dengan ArcGIS Online yang dikembangkan oleh ESRI. Secara keseluruhan, ruas jalan yang dipilih memiliki karakteristik untuk lingkungan walkable antara kawasan perumahan dan kawasan komersial. Lingkungan pejalan kaki yang paling nyaman diidentifikasi di daerah pemukiman karena trotoarnya menarik, dibangun di lereng datar, ditanami pohon teduh yang lebat, dan memiliki lalu lintas dengan volume rendah. Di kawasan komersial, lingkungan pejalan kaki kurang atraktif karena minimnya pepohonan dan kurang aman karena penggunaan jalan pejalan kaki yang beragam karena pintu masuk toko. Hasilnya mencerminkan kebutuhan perbaikan alat bantu audit di masa depan.Kata Kunci: ramah bagi pejalan kaki, GIS, audit lingkungan, hunian, komersial
