Abstract

Sustainable Development Goals (SDGs) in protecting marine and coastal ecosystems and reducing the risk of natural disasters can be achieved through mangrove planting activities at Cemara Beach. Mangroves are useful in maintaining ecosystem balance, protecting the coastline from abrasion and absorbing carbon dioxide which can reduce the impact of climate change. Mangrove planting activities involve local communities in the planting and maintenance process, and contribute to improving community welfare and environmentally-based economic development. Mangrove planting activities use seedlings aged 3 to 6 months. Mangrove planting is in a location with a water depth of 10 to 50 cm. The size of the mangrove seedlings planted is 15 to 30 cm. The type of mangrove planted at Cemara Beach is Rhizophora. Mangrove planting activities support SDGs 13, 14, dan 15 tentang climate action, life below water, and life on land.

Abstract

Cold Emulsion Asphalt Mixture (CAED) uses unheated emulsified asphalt, thus reducing gas emissions and health risks for workers. Volumetric characteristics and aggregate gradation are very important to assess the quality of CAED. Therefore, the purpose of this study is to examine the volumetric characteristics of CAED, namely Void in Mix (VIM), Void in Mineral Aggregate (VMA), and Void Filled with Bitumen (VFB), with variations in filler (cement, lime) and aggregate gradation (dense, open). The study used a laboratory experimental method, including material preparation, sample preparation with five variations of filler, testing VIM, VMA, and VFB values, and data analysis. This study shows that the volumetric characteristics of CAED with closed and open gradations meet the VMA and VFB specifications, but the VIM value is only met in the closed gradation of CAED with a variation of 50% cement:50%. Better aggregate interlocking in closed gradations results in smaller air voids. Closed gradations are recommended for heavy traffic, while open gradations are suitable for well-drained roads and light traffic

Abstract

Final-year students of the Civil Engineering Department are the spearhead of the University of Mataram's output. They need to be provided with comprehensive academic knowledge and skills to enable them to adapt to a flexible workplace. This is especially true in the current era of drought, which is a significant concern, making it crucial to provide students with the efficient use of water for crop irrigation. Therefore, final-year students need to be encouraged to undertake field-level learning to complement their knowledge and skills before completing their studies. Therefore, it is necessary to mentor final-year students in the design and use of water-efficient drip irrigation systems at the field level for a specific period of time to improve their competency until they are able to use drip irrigation in agriculture. This activity aims to mentor final-year students in the design and use of drip irrigation systems at the dryland level in Pujut District, Central Lombok Regency. The mentoring activities include site preparation, network preparation, drip irrigation network testing, and the use of drip irrigation in the planting medium. The irrigation design uses ¾-inch and ½-inch PVC pipes, factory-made Netafim (NTF) drip pipes, a 600-liter water tank as the water source, and accessories. Students were mentored through the stages of creating a distribution network, designing a drip irrigation network, testing it, and implementing it on their planting areas. The mentoring program successfully guided four final-year students and local residents, and the students were able to construct a drip irrigation network on approximately one acre of land. The students have successfully implemented the drip irrigation system.

Abstract

School safety and how well buildings work are very important for creating good learning environments, especially in rural areas.  The goal of this community service program was to make SD 4 Lenek, East Lombok, a safer place for students by (1) fixing up the school buildings and (2) raising awareness about Occupational Safety and Health (K3) among teachers, staff, and students.  The activities included checking the facilities, making small repairs to the building, putting up safety signs, making evacuation routes, and an interactive K3 seminar given by the authors as guest speakers.  The evaluation results showed that building safety indicators had gotten better and that K3 knowledge among school stakeholders had grown. This was shown by a big jump in post-test scores.  This program stresses that combining physical revitalization with safety education is very important for making schools safer.

Abstract

Damage to road pavement construction before reaching its planned lifespan can be caused by asphalt being easily oxidized and vulnerable to sunlight exposure.  Therefore, materials resistant to high temperatures should be used. One effort that can be done is modifying asphalt with zeolite. Zeolite contains silica, which can increase the binding strength between asphalt and aggregate and reduce the sensitivity of asphalt to temperature. The aim of this study is to analyze the characteristics of zeolite-modified asphalt with 3%, 5%, and 7% of the modified asphalt weight and its performance when applied to hot-mix asphalt. Asphalt characteristic tests include penetration tests, softening points, flash points, ductility, loss on heating, and specific gravity. Hot mix asphalt tests include the ability of the mixture to withstand loading, melting, Marshall quotient, Marshall immersion, and retained stability index. Based on the analysis, it can be concluded that the use of zeolite as an asphalt modifier increases the resistance to temperature changes of modified asphalt. The performance of hot-mix asphalt improved when using zeolite-modified asphalt compared to traditional asphalt mixtures. The recommended percentage of zeolite is 5% of the weight of modified asphalt, and the residual strength index achieved is 91.1%.
