Abstract

Performance of Hollow Asphalt Mixtures Using Empty Palm Oil Bunches Waste Based on Road Engineering Association of Malaysia (Ream) Specifications. One of the road pavement technologies currently being developed is porous asphalt. One of the materials used in flexible pavement mixtures is filler, one of which is ash. stone, which is in limited supply and relatively expensive. One alternative solution is to use empty oil palm fruit bunches. waste as an alternative material in the asphalt mixture. The aim of this research is what is the microstructure of asphalt mixtures that use empty oil palm fruit bunches as filler. This research uses the specifications of the Road Engineering Association of Malaysia (REAM, 2008). From the results of the research carried out, it can be concluded that the use of stone ash filler from empty palm fruit fruit bunches in hollow asphalt mixtures with variations of 2.5%, 5% and 7.5% shows that the granules are dense with voids that cover each other with varying sizes. This is in line with the stability value obtained from the Marshall test. Which has increased due to interlocking of interlocking grains. Meanwhile, from the EDS test results on the composition of chemical elements, it is known that the element contained in the hollow asphalt sample mixed with ash from burning empty oil palm fruit bunches with the highest compound composition is the element Boron at 66.55%, which is different from the chemical composition test for burning ash from bunch waste. The highest compound composition based on atomic percentage is Potassium (K) at 31.6%.

Abstract

Concrete is the main material in infrastructure development throughout the world. Its high mechanical strength and durability make it the main choice in various construction applications, from roads to high-rise buildings. However, behind its benefits, concrete production also triggers serious environmental problems. Natural aggregates such as river sand are used on a large scale. One of the materials that can be used as a substitute for fine aggregate is iron ore sediment waste. This study aimed to analyze the characteristics of fresh concrete using iron ore sediment waste as a substitute for fine aggregate using experimental methods. This study aimed to analyze the characteristics of fresh concrete using iron ore sediment waste as a substitute for fine aggregate using experimental methods. From the results of testing iron ore sediment waste aggregates such as the characteristics of iron ore sediment waste aggregates, 71% met the requirements as a material for making concrete, except for the mud content and organic content so special treatment is needed, namely the iron ore sediment waste material must be washed clean before use. The characteristics of iron ore sediment waste concrete have requirements from the average slump test value of 9 cm and there is no segregation and bleeding in the fresh concrete mixture.

Abstract

Indonesia faces significant challenges regarding energy consumption in the building sector, which continues to rise alongside urbanization and economic growth. Energy use in commercial buildings, particularly office and educational facilities, significantly contributes to the national total energy consumption, with HVAC (Heating, Ventilation, and Air Conditioning) systems being a major component of building energy consumption. By modeling HVAC systems, natural lighting, and thermal insulation, Building Information Modeling (BIM) can help optimize energy usage and reduce operational costs in buildings. However, despite the proven benefits of BIM in energy analysis and thermal comfort, challenges remain in its implementation. Many construction projects still rely on traditional methods that are less effective in integrating data and analysis. Additionally, a lack of understanding about BIM usage among construction professionals also hinders the achievement of optimal energy efficiency.

Abstract

Concrete, as one of the main elements in construction, has received special attention and is commonly used in infrastructure development in various countries in the world. High-quality concrete is increasingly needed along with the increasing need for infrastructure, such as towers, high-rise buildings, and long-span bridges. This type of concrete is made with a low amount of FAS; FAS or water-to-cementitious ratio is the ratio of the total weight of water to the total weight of cement in the concrete mixture. The purpose of this study is to analyze the water absorption of concrete using palm shells as a substitute for fine aggregate using an experimental method by curing. From the results of testing palm shells such as the water absorption value which is directly proportional to the increasing percentage of CKS use as a substitute for fine aggregate, it show that the use of CKS as a substitute for fine aggregate in normal concrete increases the water absorption of concrete, the higher the percentage of palm shell substitution, the higher the percentage of absorption value obtained.

Abstract

This study aims to estimate tsunami arrival times and wave heights at Ujung Bulu Beach and Bira Beach, Bulukumba Regency, using numerical simulations with the Cornell Multi-grid Coupled Tsunami Model (COMCOT). Two potential tsunamigenic earthquake scenarios were considered: the West Nusa Tenggara segment of the Flores Back-Arc Thrust (Mw 7.5) affecting Ujung Bulu District, and the eastern segment of the Selayar Fault (Mw 7.2) impacting Bira Beach in Bontobahari District.Modeling results indicate that tsunami arrival times at Ujung Bulu range from approximately 46 minutes at the coastline to 56 minutes inland, with modeled wave heights varying between 0.02 and 1.96 m. In contrast, Bira Beach experiences significantly shorter arrival times, ranging from 3 to 6 minutes, with wave heights between 0.10 and 10.00 m. The reported tsunami heights represent the maximum modeled water surface elevation above mean sea level at each location.These results highlight the near-field tsunami hazard at Bira Beach and the moderate but widespread inundation potential in Ujung Bulu District. The findings provide important implications for disaster risk reduction in Bulukumba Regency, including improvements in early warning dissemination, evacuation planning, and community preparedness. Nevertheless, the results are subject to uncertainties associated with earthquake source parameterization, bathymetric resolution, and numerical modeling assumptions.

Abstract

Permasalahan sampah rumah tangga masih menjadi isu penting di kawasan perkotaan, termasuk di Kelurahan Borong, Kecamatan Manggala, Kota Makassar. Kelurahan Borong merupakan salah satu wilayah administrasi di Kecamatan Manggala yang tercatat memiliki 65 RT dan 12 RW, sehingga aktivitas rumah tangga masyarakat berpotensi menghasilkan sampah domestik dalam jumlah cukup besar. Urgensi kegiatan ini juga didukung oleh Satu Data Kota Makassar yang mencatat timbulan sampah harian Kecamatan Manggala pada tahun 2024 sebesar 116,52 ton per hari Daga, R., Haya, R., Agriyani, D., & Suyuti, N. F. (2025).. Kondisi tersebut menunjukkan perlunya edukasi dan pendampingan masyarakat dalam pengelolaan sampah berbasis sumber agar tidak seluruh sampah rumah tangga berakhir di tempat pembuangan akhir. Kegiatan Pengabdian kepada Masyarakat ini bertujuan untuk meningkatkan pengetahuan, kesadaran, dan keterampilan warga Kelurahan Borong dalam menerapkan pengelolaan sampah terpadu limbah rumah tangga. Metode kegiatan dilakukan melalui sosialisasi, penyuluhan, diskusi partisipatif, demonstrasi pemilahan sampah, serta praktik sederhana pengolahan sampah organik dan anorganik. Daga, R. (2021) jenis sampah, pemilahan sampah dari sumber, penerapan prinsip 3R yaitu reduce, reuse, recycle, pengolahan sampah organik menjadi kompos, serta pemanfaatan sampah anorganik yang masih memiliki nilai guna dan nilai ekonomi. Prinsip 3R sejalan dengan pendekatan pengelolaan sampah ramah lingkungan yang menekankan pengurangan, penggunaan kembali, dan pendaurulangan sampah. Hasil kegiatan menunjukkan bahwa masyarakat mulai memahami pentingnya pemilahan sampah sejak dari rumah tangga sebagai tahap awal pengelolaan sampah terpadu. Peserta kegiatan memperoleh pemahaman bahwa sampah organik, seperti sisa makanan dan daun kering, dapat diolah menjadi kompos, sedangkan sampah anorganik, seperti botol plastik, kardus, dan kemasan bekas, dapat dipilah untuk dimanfaatkan kembali atau disalurkan melalui mekanisme bank sampah. Kegiatan ini juga mendorong perubahan cara pandang masyarakat bahwa sampah bukan hanya limbah yang harus dibuang, tetapi juga sumber daya yang dapat dikelola secara produktif apabila dilakukan secara sistematis dan berkelanjutan. Dengan demikian, pengelolaan sampah terpadu limbah rumah tangga di Kelurahan Borong Kota Makassar dapat menjadi strategi pemberdayaan masyarakat dalam mendukung kebersihan lingkungan, pengurangan timbulan sampah, dan peningkatan kesadaran ekologis warga. Program ini perlu dilanjutkan melalui pendampingan berkala, pembentukan kelompok pengelola sampah, penguatan bank sampah, serta kerja sama antara masyarakat, pemerintah kelurahan, dan instansi lingkungan hidup. Penguatan kelembagaan pengelolaan sampah juga sejalan dengan ketentuan nasional bahwa pengelolaan sampah harus dilakukan secara sistematis, menyeluruh, dan berkesinambungan, termasuk melalui peran masyarakat dan pengelolaan bank sampah.
