Abstract

Cibeuteung River is one of the rivers that is used as a tourist destination. The Cibeuteung River is a potential natural resource that can be developed as an ecotourism object and attraction. So this study aims to determine the identification of the potential of Cibeuteung river resources for rafting ecotourism, which is focused on knowing the characteristics of the rafting path, river slope, water discharge, river width and accessibility. This research uses survey method. Data was collected by using field observation and documentation techniques. Data analysis with descriptive analysis. The results showed that the river rafting route in Cibeuteung River has a river width of about 68 m to 98 m, a river slope of 0.5% to 0.3%, with a maximum discharge of 169.79 m3/s and a minimum of 26.03 m3/s. s in the dry season. Based on time, the starting point of the white water rafting route is 30 km (55 minutes) from downtown Bogor and 19 km (53 minutes) from downtown Depok. As well as from the analysis results Cibeuteung River has a start and finish point location that is easily accessible.

Abstract

Problem utama jalan pedesaan di Indonesia adalah masih banyaknya jalan yang belum di aspal atau di beton karena keterbatasan dana. Akibatnya jalan desa tersebut seringkali mengalami kerusakan apalagi di musim hujan, sehingga menjadi penghambat transportasi dan kegiatan ekonomi. Salah satu solusi untuk mengatasi hal tersebut melalui inovasi pembuatan jalan dengan memanfaatkan soil stabilizer. Soil stabilizer adalah bahan aditif yang ramah lingkungan, dapat diaplikasikan untuk jalan desa. Campuran yang digunakan pada pekerjaan jalan desa adalah tanah dicampur semen kemudian ditambahkan soil stabilizer. Benefit soil stabilizer dapat meningkatkan kekuatan California Bearing Ratio(CBR) tanah dan mengurangi sweeling. Pada program Pengabdian masyarakat ini dilakukan Aplikasi soil stabilizer untuk jalan desa Kiarasari Kecamatan Sukajaya Kabupaten Bogor.

Abstract

The cement industry significantly contributes to CO2 emissions, releasing approximately 1 ton of CO2 for every ton of cement produced, which accounts for up to 40% of total global industrial emissions. This study aims to mitigate these emissions by utilizing Palm Oil Boiler Ash (POBA) as a clinker substitute, creating POBA Cement with substitution levels ranging from 10% to 30%. The POBA was sourced from the Cikasungka Palm Oil Plantation in Bogor, Indonesia and underwent analysis using X Ray Fluorescence (XRF) andScanningElectron Microscopy (SEM) to assess its chemical properties and microstructure. The findings revealed a decrease in compressive strength with increased POBA substitution levels; however, it maintained a pozzolanic effect that supported the crystallization process, albeit with a longer setting time compared to Ordinary Portland Cement (OPC). Notably, the addition of 1% nano-silica was found to enhance compressive strength more effectively than 3%. This research underscores the potential of POBA as an environmentally friendly clinker substitute for sustainable cement production.

Abstract

This study investigates the mechanical performance of sustainable concrete incorporating Palm Oil Boiler Ash (POBA) as a partial cement replacement. As the construction sector seeks to reduce CO₂ emissions and manage agro-industrial waste, POBA emerges as a promising supplementary cementitious material due to its pozzolanic potential and abundance in palm oil–producing regions such as Indonesia.Concrete specimens were prepared with POBA substitution levels ranging from approximately 10% to 30% by weight of cement, in combination with nanosilica and a polycarboxylate ether (PCE) superplasticizer to enhance performance. The mix design was developed in accordance with ACI 211 guidelines to maintain comparable workability across all mixtures.Compressive strength was evaluated at 3, 14, 28, and 56 days. Results indicate that while early-age strength decreases with increasing POBA content, an optimal replacement level of 19% demonstrated compressive strength comparable to the control mixture at later ages under the tested mix design conditions. The inclusion of nanosilica, based on prior experimental validation, is considered to have contributed to mitigating early strength reduction and supporting microstructural development. The study concludes that POBA, when applied at an optimal replacement level, can serve as a viable partial cement substitute for structural concrete applications, supporting environmental sustainability and low-carbon infrastructure development.
