The longhouse is a well-known traditional dwelling of many natives in Sarawak. A longhouse is a terraced street of separate dwellings covered by one roof. Each family who stay in the longhouse has their separate room. These houses are still in use today and are able to provide the basic shelter needs of the occupants. The use of local materials and the setting that create harmonization with the local environment and climate contribute to the provision of comfort to the occupants. However, the traditional longhouse today is a threatened typology as some of them either have disappeared, are no longer constructed, are tourism attractions or are being maintained as cultural artifacts only. There is a concern that someday the distinct identity of the longhouse might be lost. Therefore, knowledge of construction techniques, assessment of the materials used and typological characteristics of the traditional architecture need to be gathered to preserve the built heritage. A comprehensive document is essential for the preservation and conservation of the traditional longhouse. This paper presents the methodology used and data collected on the typology of the traditional longhouse and its construction method.

Fifteen years since the 2004 Indian Ocean tsunami, which caused massive destruction around the Andaman Sea, people have participated in efforts to reduce tsunami risks in Indonesia. However, the most important question continues to be on whether such efforts are sufficient in dealing with tsunami risks. Among the most striking challenges here is bridging the gap in tsunami risk reduction between the Sumatra mainland and among communities in several small islands. Thus, this research aims to investigate the recent conditions of selected towns/cities in tsunami-prone small islands and identify the impediments to their tsunami hazard preparedness. It focuses on comparing efforts in terms of available facilities for tsunami evacuation plans and the tsunami estimated time of arrival (ETA), which is computed based on deterministic tsunami propagation models. In this regard, five of the observed locations are classified as being in a critical tsunami preparedness condition, namely Balai island, Lahewa of Nias Island, Sabeugunggung of North pagai Island, Surat Aban of South Pagai island, and Enggano Island. Most of them have limited space for tsunami evacuation and a short tsunami ETA, which constitutes an extreme condition requiring immediate tsunami mitigation measures. One possible approach is to construct a vertical tsunami evacuation building or modify existing buildings that can be used for tsunami evacuation on the islands. This article also highlights societal aspects related to tsunami preparedness.

Power generation is a business that ought to satisfy industrial and consumer electrical power needs. Power generation technology has emerged from conventional power plants, which are mostly steam power plants, evolving into more complicated nuclear power plants. While the mechanical arrangements in the power plants are usually unique and distinct from one another, their electrical assemblies are almost the same; the major factor considered is sizing of the electrical equipments. The electrical generator is therefore one of the fundamental equipment that every power plant must have. In principle, the generator is crucial equipment that needs proper maintenance in order to produce steady output supply. The objective of this study is to is to conduct on-site partial discharge monitoring system of 3 unit generators stator winding at Tanjung Bin Power Plant, Johor, Malaysia as condition based monitoring (CBM) system. Partial discharge characteristics of unit 10, 20 and 30 generators stator winding were compared respectively. Software designed by Iris LP was used throughout these processes. The software-PDView demonstrates graphical view of the partial discharge occurrence in the generator stator winding. Compiled data were analyzed using Microsoft Excel in order to establish an evaluation of the generator stator winding. The analyzed results showed that all generators were in good condition.
