Abstract

Proses pemancangan seringkali mengalami kendala dalam mengantisipasi keberadaan rongga ataupun gua dalam tanah yang akan mempengaruhi kegagalan daya dukung friksi atau bahkan kegagalan daya dukung ujung pada tiang pancang. Komposisi batuan yang berada pada pondasi tiang bor dan tiang pancang yang memiliki karakteristik batuan gamping terumbu yang cenderung porous dan berongga perlu mendapat perhatian khusus. Penyelidikan dengan menggunakan geolistrik membantu proses identifikasi secara cepat untuk mengetahui kondisi tanah dan batuan yang berada pada lintasan-lintasan tertentu ada posisi pier dan abutmen yang ditengarai menembus lapisan tanah dan batuan berongga dan dikhawatirkan akan berada di lapisan yang berongga atau goa kapur. Pengujian geolistrik dilakukan dengan menggunakan 3 lintasan pengukuran yang masing-masing berada pada lajur centre line, sisi kiri dan sisi kanan grup tiang. Hasil pengukuran disandingkan dengan hasil pengeboran menunjukkan bahwa posisi rencana tiang pancang berdiri pada lapisan tanah dan batuan yang masif dengan komposisi batuan gamping terumbu berselang-seling dengan rekahan dan rongga, clayshell dan marmer atau batuan intrusi yang keras. Sementara rongga dengan diameter yang lebih besar dan terindikasi sebagai goa juga ditemukan pada beberapa tempat di sekitar rencana penempatan tiang bor/tiang pancang.

Abstract

Soil is one of the factors that has the most important role because it bears the burden of all the constructions that stand on it. Based on this very important role of soil, prior to the start of construction in a location, a soil investigation must be carried out first to find out the condition of the subgrade at the construction site. One of the most frequently used soil investigation methods is Cone Penetration Test (CPT). The purpose of this study includes two things, namely to determine the soil profile at the CPT test location, and to determine the correlation between the data from the Cone Penetration Test results with soil parameters (Soil Volume Weight, Cohesion, and Internal Shear Angle). The method used in this study is to analyze the data from the Cone Penetration Test using the results of the research that has been carried out as a basis for determining the soil profile and the required soil parameters. The results obtained are, the first is based on the data plot on the soil type graph at the Cone Penetration Test (CPT) test location spread over 4 zones, namely Zone 3, Zone 4, Zone 5, and Zone 6. The second is the correlation between soil unit weight and Conus Resistance values are directly proportional, as are Cohesion and friction angles. In addition, the equations used in this paper cannot be used as the main reference, but only used to predict soil parameters when in the field

Abstract

Building Information Modelling (BIM) adalah sebuah pendekatan untuk desain bangunan, konstruksi, dan manajemen. Software Tekla merupakan revolusi baru dalam bidang rekayasa struktur yang memiliki beberapa keunggulan dibanding program aplikasi lainnya. Tekla Structures merupakan perangkat lunak Building Information Modelling (BIM) yang memungkinkan untuk membuat dan mengelola data secara akurat dan rinci, serta dapat membuat model struktur 3D tanpa melupakan material dan struktur yang kompleks. Penggunaan BIM di Indonesia masih hanya sebatas menjawab persoalan bagaimana mengefisiensikan kebutuhan tenaga kerja, waktu dan uang. Jika kita berkaca pada bagaimana pengaplikasian metode BIM di negara lain, potensi yang dicapai dari pengaplikasian metode BIM di Indonesia masih jauh dari kata maksimal. Tantangan selanjutnya adalah bagaimana mengenalkan teknologi aplikasi BIM ini dan mendorong penerapan BIM ini ke seluruh pihak stakeholder sektor konstruksi yang terkait. Maka dari itu, kegiatan pengabdian pada masyarakat ini bertujuan untuk memberikan pengenalan tentang Building Information Modelling dan memberikan keterampilan dasar dalam penggunaan aplikasi teknologi BIM dengan software Tekla Structures. Kegiatan ini dilaksanakan di Departemen Teknik Sipil, Universitas Hasanuddin yang dihadiri oleh 35 peserta yang berasal dari kalangan praktisi dan akademisi. Tahapan kegiatan pengabdian meliputi kegiatan sosialiasi ke stakeholder melalui mitra Lembaga Pengembangan Jasa Konstruksi Provinsi Sulawesi Selatan (LPJKP Sul-Sel), pengumpulan data berupa shop drawing, pembuatan modul, pemodelan dan laporan berupa quantity dan gambar kerja.

Abstract

Kerusakan jalan sebagian besar disebabkan oleh rendahnya kapasitas dukung dari lapisan pondasinya dalam menerima beban kendaraan yang melintas diatasnya. Hal ini tidak lepas dari sifat material timbunan yang digunakan, baik itu sirtu, kerikil, maupun tanah. Material timbunan yang baik adalah material yang mempunyai daya dukung tinggi namun tidak menjadi beban untuk lapisan dibawahnya. Material timbunan ringan merupakan solusi untuk mereduksi kerusakan jalan akibat lapis pondasi pada konstruksi jalan. Penelitian ini bertujuan mengembangkan material timbunan geokomposit ringan dengan mengganti sebagian tanah lempung dengan expanded polysterene (EPS) yang distabilisasi dengan limbah aspal buton (LAB). Variasi limbah aspal buton yang digunakan sebesar 3%,5%,7% dan 9%, sementara variasi EPS yang diberikan sebesar 0,1% dan 0,2%. Pemeraman benda uji dilakukan selama 7 dan 28 hari. Hasil pengujian menunjukkan bahwa subtitusi tanah dengan EPS mampu mereduksi kepadatan sebesar 20% hingga 30%, adapun nilai CBR meningkat sebesar 7 kali pada EPS 0,15% dan 4 kali pada EPS 0,30%. Berdasarkan hasil tersebut, maka geokomposit ringan tanah-EPS stabilisasi LAB dapat dijadikan sebagai timbunan alternatif baik sebagai lapis pondasi bawah (LPB) pada jalan maupun backfill dibelakang dinding penahan tanah.

Abstract

The National Community Empowerment Program's village and sub-district officials who oversee development financing must execute Technical Guidance in the context of creating a Draft Cost Budget for the construction of Highways, Civil Works, and Water Resources. To help the Construction Development Institute teach and provide technical advised to all village fund managers so they can stay on task and prevent the misuse of state financial management, academics are needed. The purpose of this activity is to provide understanding to village and sub-district officials so that they prioritize planning activities, budget calculations, material needs to implementation in accordance with quality standards and good accountability. All officials throughout Maros Regency are invited to attend or send their envoys as Technical Guidance participants. Subsequently, a coaching clinic method was implemented, wherein the Construction Cost Estimate (RAB) was prepared in an intense manner to maximize training outcomes right away. This method allows us to directly examine participants' comprehension of AHSP and RAB compilation, as well as directly rectify the way participants begin calculating. From the post-test results, data on the understanding of village staff on AHSP has reached 73% and understanding in preparing the RAB has exceeded 60%. Keywords: Technical Guidance, National Community Empowerment Program's, AHSP, RAB compilation, coaching clinic.

Abstract

Makassar is one of the cities in Indonesia that is unlikely to be free from natural disasters. The problem is that the community, especially school-age children, is not yet responsive and alert and does not understand disaster preparedness's importance. Low knowledge, lack of information provision, and disaster risk management can increase the number of victims. Athirah Islamic School, one of the partners in this service, provides facilities for Psychoeducation activities for students. From this problem, a solution for disaster risk reduction is needed by giving psychoeducation (disaster mental health) and disaster preparedness around general reactions (behavior, emotion, cognition, and physical). Psychoeducation materials will be delivered by the Bosowa University psychology team, also partners in this Service activity. The implementation method of this service program includes mentoring and disaster preparedness training from a psychological perspective. The research method used in this service is experimental with a pretest-posttest design approach. The statistical analysis results showed a difference in student knowledge regarding disaster preparedness before and after participating in psychoeducation with a sig <0.05. This service concludes that the training provided to Athirah Bukit Baruga Islamic Middle School students positively impacts students' disaster preparedness knowledge.

Abstract

This research examines coastal erosion in North Galesong, Indonesia, by validating longshore sediment transport (LST) equations and predicting shoreline changes over ten years. To evaluate sediment movement and coastline alterations, it integrates field data on sediment grain size and wave characteristics with numerical modeling techniques, including the CERC equation and finite difference methods. Sieve analysis revealed a range of sediment textures (D50: 0.17–0.65 mm), predominantly medium-fine sand. Wave analysis indicated a dominance of moderate energy southwesterly waves (1.5 m height, 6.39 s period) that aid sediment transport. The empirical LST models, calibrated with local data, closely matched numerical simulations (error <20%), predicting an annual net northward sediment transport of 406,869 m³. Shoreline analysis across 15 segments showed significant spatial variability: severe erosion occurred in Cell 4 (Δy = -0.82 m), while Cell 3 saw accretion (Δy = +0.68 m), influenced by wave direction, sediment supply, and coastal morphology. This study underscores the value of hybrid empirical-numerical methods in data-scarce regions and emphasizes the need for local model calibration to enhance coastal resilience. The findings inform sustainable management practices, promoting adaptive strategies to address sediment imbalances and hydrodynamic changes due to climate factors.

Abstract

This study investigates the combination of Fly Ash (FA), Bottom Ash (BA), and Soil (S) as a potential bottom liner in landfills. It is expected to cover the need for sustainable environmental technology, maintain structural strength, and prevent heavy metal pollution in rapidly urbanizing areas, while considering problems related to urban waste management. Aim: Evaluate FABA-Soil mixture as an alternative bottom liner material in landfill by assessing geotechnical performance and Cadmium (Cd) adsorption capacity. Methodology and results: The research explores two issues: mechanical stability (specific gravity, void ratio, compaction, and permeability) and mitigating Cadmium contamination from landfill leachate. Four mixture compositions (FBS1-FBS4), 15%, 30%, 50%, and 65% FABA content, were tested. Laboratory tests are conducted, including compaction, permeability, and adsorption continuous column tests. The results showed that intermediate FABA content (FBS2 and FBS3) may have stronger mechanical stability compared to others. For permeability, all values exceeded the regulatory standard. In the case of adsorption capacity, all compositions effectively removed Cd from the leachate. Conclusion, significance, and the impact study: Results on void ratio (e) and maximum dry density (MDD) suggested that a suitable mixture design may enhance long-term mechanical performance under a normal urban landfill loading situation. The FABA-soil mixture shows promise as an alternative landfill liner in moderate proportions and demonstrates excellent adsorption of heavy metals. All the attributes support general objectives of sustainable urban development and circular resource management, align with sustainable cities and communities, and responsible consumption and production.
