Abstract

Respiratory complaints are a health problem that can be experienced by construction workers, especially welding workers, primarily due to exposure to Carbon Monoxide gas. This study aims to analyze the relationship between carbon monoxide (CO) gas exposure and respiratory Personal Protective Equipment (PPE) usage behavior with respiratory complaints among welding workers. This research is an analytical observational study with a cross-sectional design conducted at PT. X in Batam City, Riau Islands from February to July 2024. The entire population of 35 welding workers was taken as a sample through the total sampling method. Based on the research results, the chi-square statistical test shows a p-value of 0.030 < α = 0.05 for the relationship between CO gas exposure and respiratory complaints, so Ho is rejected and Ha is accepted. This means that there is a significant relationship between exposure to carbon monoxide (CO) gas and respiratory complaints in workers. Furthermore, the chi-square statistical test for the relationship between PPE usage behavior and respiratory complaints resulted in a p-value of 0.046 < α = 0.05, so Ho is rejected and Ha is accepted, which means there is a significant relationship. The results of this study show that 74% of workers were exposed to CO gas above the threshold limit value (25 ppm), 60% used respiratory PPE, and 63% experienced respiratory complaints. Suggestions for the company include evaluating working hours, periodic health monitoring, improving ventilation, optimizing PPE usage, and further research on lung function disorders using spirometry.

Abstract

Abstrak Kegiatan pengabdian ini bertujuan untuk meningkatkan pemahaman dan kapasitas dosen dalam menyusun proposal penelitian dana hibah yang berkualitas. Sejak berdirinya Fakultas Teknik dan Rekayasa (FTR) diketahui bahwa dosen penerima dana hibah penelitian sangat minim. Dosen Fakultas Teknik yang pertama menerima dana hibah diketahui dimulai tahun 2024 yaitu sebanyak 2 orang sebagai ketua tim peneliti. Setelah dilakukan observasi, ditemukan berbagai kendala dalam menyusun proposal penelitian hibah seperti ketidaktepatan perumusan masalah, ketidaksesuaian metodologi, ketidakjelasan luaran, serta kesalahan umum seperti administrasi yang dapat mempengaruhi kelayakan proposal. Dalam mengatasi masalah tersebut, dilakukan kegiatan yang berbentuk sosialisasi dan Sharing Session dengan pendekatan edukatif dan partisipatif sehingga terjadi diskusi dan interaksi dua arah dengan peserta. Kegiatan pengabdian ini diikuti oleh 15 peserta yaitu dosen yang tersebar di Fakultas Teknik dan Rekayasa. Hasil evaluasi kegiatan ini menunjukkan peserta mengalami peningkatan pemahaman di keempat aspek tersebut. Perbaikan secara signifikan terjadi pada aspek administrasi, substansi dan luaran khususnya pada format penulisan, referensi, RAB, latar belakang, rumusan masalah, tujuan dan keterukuran luaran serta pemilihan rumah jurnal. Sementara itu, parbaikan pada aspek metodologi memiliki kecenderungan bersifat penyempurnaan sehingga perubahan yang terjadi relatif lebih sedikit meskipun tingkat pemahaman sangat tinggi. Secara keseluruhan, kegiatan pengabdian ini efektif dalam mendorong peserta untuk merefleksikan dan memperbaiki kualitas proposal penelitian yang disusun. Pendekatan sosialisasi dan Sharing Session terbukti mampu meningkatkan pemahaman dan kesadaran peserta terhadap aspek-aspek penting dalam penyusunan proposal penelitian, sehingga berpotensi mendukung peningkatan kualitas pengajuan penelitian pada periode selanjutnya. Kata kunci: pengabdian kepada masyarakat; proposal penelitian; pendampingan dosen; peningkatan kapasitas; evaluasi proposal. Abstract This community service activity aims to enhance lecturers’ understanding and capacity in preparing high-quality research grant proposals. Since the establishment of the Faculty of Engineering, the number of lecturers who have successfully obtained research grants has been very limited. Records indicate that the first lecturers from FTR to receive research funding only emerged in 2024, involving two lecturers serving as research team leaders. Preliminary observations revealed several common obstacles in proposal preparation, including inaccurate problem formulation, inappropriate methodological design, unclear and unmeasurable research outputs, as well as administrative deficiencies that may affect proposal feasibility. To address these challenges, this community service program was implemented through socialization activities and Sharing Sessions using an educational and participatory approach. This approach facilitated two-way discussions and active interactions between the facilitators and participants. The activity was attended by 15 lecturers from various departments within the Faculty of Engineering. Evaluation results indicate an overall improvement in participants’ understanding across four key aspects: administration, substance, methodology, and outputs. Significant improvements were observed in administrative, substantive, and output aspects, particularly in writing format, referencing, budget planning (RAB), background formulation, problem identification, research objectives, output measurability, and journal selection. Meanwhile, methodological improvements tended to involve refinement rather than major changes, reflecting a high level of initial understanding. Overall, this community service activity was effective in encouraging participants to reflect on and improve the quality of their research proposals and is expected to support higher-quality research submissions in future funding periods. Keywords: community service; research proposals; lecturer mentoring; capacity building; proposal evaluation.

Abstract

Oil palm fruit production in East Kalimantan continues to increase in line with high market demand. This situation demands efficient transportation facilities to transport the harvest from plantation areas. Furthermore, annual forest fires, particularly in peatland areas, are often difficult to manage due to limited land access. Based on these two challenges, this study proposes the design of a multipurpose vessel capable of both transporting oil palm fruit and supporting firefighting. The vessel is designed with main dimensions of L = 20 m, B = 4.9 m, H = 2 m, T = 1.5 m, and an operating speed of 8 knots. The cargo hold has a carrying capacity of 67.3 tons with a single trip distance of 12.3 km. The main innovation developed is a conveyor belt with hydraulic arms to increase the efficiency of the oil palm fruit loading and unloading process in the plantation area. Furthermore, the vessel is equipped with an external firefighting system with a capacity of 90 m³/hour with a horizontal spray range of 30 meters and a vertical height of 20 meters. The fire monitor operates using 7 kW of power to generate sufficient pressure to extinguish fires in areas difficult to reach from the riverbank. This multipurpose vessel is designed to provide an integrated solution for the oil palm plantation logistics chain while improving the response to forest fires in the Muara Kaman District.

Abstract

Longitudinal strength is a fundamental aspect of barge structural safety because variations in loading magnitude and load position may significantly affect the global hull girder response. This study evaluates the longitudinal strength of a cargo barge based on shear force and still water bending moment under several loading conditions, with reference to the applicable BKI Rules for longitudinal strength assessment. The object of the study is a cargo barge with principal dimensions of 330 ft × 90 ft × 21 ft and a lightship weight of 1802.9 metric tons. Six loading conditions were investigated, namely lightship, fully loaded, partially loaded at 50% with homogeneously distributed cargo, and three crane-shift positions at the aft, midship, and fore sections. The net load distribution was obtained from the difference between distributed weight and buoyancy, and then integrated to determine the shear force and still water bending moment along the hull. The results show that the fully loaded condition produced the most critical structural response, with a maximum shear force of 0.385 × 10³ metric tons at Frame 50 and a maximum still water bending moment of -6.212 × 10³ metric ton·m at Frame 35, indicating a dominant sagging condition. The governing case reached only 32.49% of the allowable shear force and 33.58% of the allowable still water bending moment, confirming a substantial safety margin. The crane-shift analysis further demonstrates that movable concentrated loads can shift critical internal force locations, which may be overlooked in standard cargo distribution analysis. All evaluated loading conditions remained below the permissible limits, indicating that the barge is structurally acceptable under the investigated still-water loading scenarios.

Abstract

The Polbeng Research Vessel is a small research ship developed by Politeknik Negeri Bengkalis (Polbeng) in collaboration with CV. Fatih Bahari Engineering. The vessel is constructed from High Density Polyethylene (HDPE) and has principal dimensions of 9 m length overall (LOA), 2.2 m breadth, and 1.2 m depth, powered by an 85 HP outboard engine. This study aims to evaluate the seakeeping and motion comfort performance of the vessel to support research activities involving personnel and onboard equipment. The seakeeping analysis is conducted using a frequency-domain approach based on Response Amplitude Operators (RAOs), where ship motions are evaluated under regular wave conditions. Four operational cases are considered, involving two wave heights (0.2 m and 0.4 m) and two wave encounter directions, namely beam seas (90°) and head seas (180°). Three ship motions are analyzed: heave, roll, and pitch. The results indicate that roll motion in beam seas conditions exhibits the most significant response compared to other motions, which is consistent with the theoretical characteristics of small vessels having shorter restoring arms for roll motion. Overall, the vessel’s motion responses remain within acceptable limits and satisfy established comfort criteria based on NORDFORSK 1987, STANAG 4154, U.S. Coast Guard (USCG), ISO 2631/1, ISO 2631/3, and BS 6841:1987 standards. The findings provide technical insight into the seakeeping behavior and comfort performance of HDPE-based small research vessels and serve as a reference for the design, evaluation, and development of environmentally friendly research and working vessels to enhance operational safety and effectiveness.
