Abstract

A long series of earthquakes that lasted for almost a month with the biggest shock reaching 7 SR completely destroyed most of the houses in parts of Lombok and Sumbawa. Many residents were forced to evacuate because their homes entirely devastated. Some residents have returned to their homes, but many also have no place to return. So they need temporary shelter while rebuilding their houses gradually. There are many choices of designs that have been developed before. However, designing a temporary shelter that is truly in accordance with the needs of the community at the disaster site requires a comprehensive understanding of the local human characteristics and nature as well as the local environment. Including things that must be considered is the impact on the environment if the design involves locally available nature material. The design concept was based on the concept of a barn house with bamboo and spandex-plywood materials. The first concept is a bamboo barn shelter which adopts a traditional Lombok house with woven bamboo walls. The second concept is also based on traditional Lombok houses, but uses a different material which is spandek as the dominant material for the roof and plywood as the walls and doors. Both temporary shelter concepts have been successfully designed, built and applied.

Abstract

Wood products that are currently growing rapidly in many places in the world are laminated blocks (glulam). Laminate beam has many advantages in terms of size, strength and artistic. However, this laminated beam has a few drawbacks in terms of providing tools and materials for some areas. The laminated beam itself uses an adhesive material which is relatively expensive and requires a compression tool in its implementation. Therefore, an alternative is given in the form of composite beams. Composite beams that have developed so far use shear connectors in the form of bolts, nails, and pegs as the connecting tool. Meanwhile, shear connectors using drilling bolts have never been done. Therefore, based on this, it is necessary to research composite wood beams with an alternative, namely using drilling bolts as shear connectors in order to obtain the effect of variations in the distance of drilling bolts on the flexural strength of composite beams. The results of the flexural strength test obtained the strength of the composite beam with shear connectors with the largest distance of 3.125, followed by beams with shear connecting distances of 6.25 cm, 12.5 cm and 25 cm. This shows that the closer the shear connecting distance, the greater the strength obtained, with the percentage increase in variation of 31.5%, 38.737% and 46.072%, respectively.

Abstract

The Mandalika Special Economic Zone (KEK) is key to Indonesia's economic growth. Located in southern Lombok Island, it became a Tourism SEZ via Government Regulation Number 52 of 2014. However, infrastructure development in Mandalika SEZ faces challenges, notably low investment returns. Choosing the right roads is crucial, requiring effective decision-making to attract investors and promote regional development in Central Lombok. This research used literature review and data collection through interviews and questionnaires to assess road development criteria. The Analytic Network Process (ANP) and TOPSIS methods prioritized infrastructure development. Four key criteria were identified: Tourism Infrastructure, Costs, Investor Interest, and Average Daily Traffic. The study ranks road segments for Mandalika SEZ, with the Circuit's Southern Ring Road (P5 - I1) as the top priority. This MCDA-derived prioritization provides actionable insights for policymakers and investors, enhancing strategic infrastructure investments to boost economic impact and support sustainable tourism growth. The findings validate the integration of ANP and TOPSIS in regional development planning.

Abstract

The development of the Mandalika Special Economic Zone (SEZ) faces challenges related to infrastructure that has not been fully realized, which may affect the effectiveness of the area. Adequate infrastructure is essential to support the competitiveness and sustainability of the Mandalika SEZ as a leading tourism destination. This study aims to identify the factors that influence the urgency of infrastructure development, analyze the relationships among variables, and determine the infrastructure priorities that need to be addressed immediately. This study uses an explanatory quantitative approach through stakeholder surveys and Partial Least Squares Structural Equation Modeling (PLS-SEM) analysis. The exogenous variables include infrastructure-related factors, while the endogenous variables include socioeconomic benefits, sustainability, community welfare, and tourism attractiveness. The results of the analysis show that the priorities for infrastructure development are as follows: 1) regional supporting infrastructure, 2) electricity facilities, 3) SWTP, 4) infrastructure for surrounding communities, 5) clean water and irrigation systems, and 6) WWTP. Regional supporting infrastructure has the greatest influence on socioeconomic benefits and destination attractiveness. Infrastructure development in the Mandalika SEZ needs to prioritize a value-creating infrastructure approach to improve the competitiveness and sustainability of the region. These findings provide a scientific basis for more strategic and sustainable infrastructure development planning.

Abstract

Pakuan Village is a tourist village with the potential for waterfalls and road access through hilly areas that have high disaster vulnerability. Risks such as landslides, flash floods, and slippery roads threaten the safety of the public and tourists. The main problem is the low literacy of community disaster preparedness and the limited understanding of mitigation in road infrastructure. This service activity aims to increase knowledge and awareness through disaster mitigation education. The methods used include participatory socialization, material delivery, and evaluation through pre-test and post-test. The results show an increase in public understanding of the types of disasters, how they impact road infrastructure, and simple mitigation measures that can be taken. Mitigation education has proven to be effective in increasing community preparedness and is the first step in building a disaster awareness culture in the Pakuan Village tourist area.
