Abstract

Port work areas are prone to potential hazards. This study aims to identify hazards and assess risks in the port work area, especially in the operational process of loading and unloading containers using the HIRADC method at five port work area locations in Padang City. The results show that there were 15 medium risk, 13 high risk observed. There is high risk of accidents in liquid bulk, dry bulk and container activity locations such as being crushed by containers, being hit in the container area, dust/noise and sea air pollution due to the process of loading/unloading liquid bulk and dry bulk area. The medium risk levels consist of being hit by lift transport, CO2 gas fumes and being crushed by material transport. To reduce and eliminate potential hazards, risk management is required by identifying and analysing potential hazards, assessing risks and recommending controls, one of which is the Hazard Identification Risk Assessment and Determining Control (HIRADC) method. Recommended controls include preparation of marine pollution control equipment (oil booms), operational maintenance of loading and unloading equipment, installation of signs indicating low to high hazard areas, provision of light fire extinguishers, administrative controls and use of personal protective equipment (PPE).

Abstract

This study examined the removal of nitrate from wastewater using column adsorption method with variations in the ratio of biochar and polyurethane foam, as well as variations in flow rate. The results showed that the highest adsorption capacity was obtained at a flow rate of 30 mL/min compared to other flow rate variations. At that flow rate, the nitrate sorption capacity reached 4.10 mg/g with biochar, 0.20 mg/g using biochar : polyurethane foam (1 : 1) media, and 13.12 mg/g using biochar : polyurethane foam (2 : 1) media. The biochar : polyurethane foam (2 : 1) media showed the highest nitrate adsorption capacity, which was caused by an increase in the contact time of the flow in the media due to more polyurethane foam volume. This study concludes that sufficient contact time between the contaminant and the adsorption media in the column is a key factor for nitrate removal optimization in addition to the adsorbent material used.Keywords: Adsorption, Biochar, Polyurethane foam, Nitrate ABSTRAKPenelitian ini mengkaji penyisihan nitrat dari limbah cair menggunakan metode adsorpsi kolom dengan variasi rasio biochar dan busa poliuretan, serta variasi laju alir. Hasil penelitian menunjukkan kapasitas adsorpsi tertinggi diperoleh pada laju alir 30 mL/menit dibandingkan variasi laju alir lainnya. Pada laju alir tersebut, kapasitas sadorpsi nitrat mencapai 4,10 mg/g dengan biochar, 0,20 mg/g menggunakan media biochar : busa poliuretan (1 : 1), dan 13,12 mg/g menggunakan media biochar : busa poliuretan (2 : 1). Media biochar : busa poliuretan (2 : 1) menunjukkan kapasitas adsorpsi nitrat paling tinggi, yang disebabkan oleh peningkatan waktu kontak aliran dalam media akibat kandungan busa poliuretan yang lebih banyak. Penelitian ini menyimpulkan bahwa waktu kontak yang cukup antara kontaminan dan media adsorpsi dalam kolom merupakan faktor kunci untuk optimasi penyisihan nitrat selain material adsorben yang dipakai.Kata kunci: Adsorpsi, Biochar, Busa poliuretan, Nitrat

Abstract

PT Semen Padang was the oldest cement industry in Indonesia located in Indarung, Padang City, West Sumatra. To protect the safety and health of workers, PT Semen Padang conducts an Occupational Health and Safety (OHS) Management System by controlling the Recordable Incident Rate (RIR) number. PT Semen Padang used Minister of Manpower Regulation No. 03 / Men / 1998 to calculate RIR numbers because it has more than 500 workers. The number of RIRs obtained from 2013-2017 experienced fluctuations. The highest RIR rate was 2.50 in 2016 and was above the target of PT Semen Padang, which amounted to 2.0. In suppressing the RIR figures, PT Semen Padang implemented an activity plan, in the form of inspection, socialization and information of OHS. Viewed from 2013-2017 the magnitude of the implementation of the activity plan had a significant effect on the decrease in the RIR rate in PT Semen Padang (p <0.05). The solution for RIR activity plan improvement can be in the form of increasing the frequency of inspections carried out in locations with high risk of accidents, socialization of OHS based on the type of dominant occupational accidents and proper placement of OHS information in the work area.

Abstract

Production processes in the palm oil industry pose hazards and risks of occupational accidents. PT XYZ's Palm Oil Mill (POM) unit recorded 15 accident cases in 2021-2023. This study aimed to identify occupational health and safety (OHS) hazards and assess risks at each stage of CPO production at PT XYZ's POM unit using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method. This study involved all workers at PT XYZ's POM unit. Primary data were collected through field observations and questionnaires, while secondary data were obtained from company documents. Data analysis included descriptive analysis and risk assessment using the HIRARC method. There were significant differences in risk levels between units. The Loading Ramp had the highest risk due to the intensity of activities, work at height, and heavy equipment movement. The Sorting, Sterilizer, Thresher and Digester, Press, Clarification, and Kernel units had medium risk, while the Weighbridge had the lowest risk. Human factors were the dominant cause of occupational accidents. Risk control recommendations were formulated based on the hierarchy of controls, including elimination, substitution, engineering controls, administrative controls, and the use of Personal Protective Equipment (PPE).

Abstract

University students are key agents in promoting environmental sustainability, making it essential to assess their level of knowledge, attitudes, and actions regarding environmental awareness. This study aims to evaluate environmental awareness among university students through a structured questionnaire survey. The instrument was distributed to 71 students across different academic levels at a university in West Sumatra Province. The results indicate that while most students possess a basic understanding of environmental issues, their ability to analyze, synthesize, and evaluate such issues remains limited. In terms of attitudes, students generally demonstrate positive dispositions, although further development is needed to foster active participation and social responsibility. Regarding environmentally conscious actions, students have not yet consistently adopted sustainable behaviors, particularly at the level of habitual and innovative practices. Key behaviors that require improvement include waste separation, refusal to use plastic bags, the use of reusable food containers, and recycling practices. These findings highlight the need for more practical and reflective environmental education at the higher education level. Keyword: university students, knowledge, attitude, action, environment

Abstract

Every year, the Bukik Gompong Organic Garden farmer group produces around 13 tons of coffee cherries along with waste in the form of coffee husks/cascara. The processing of coffee cherries into green beans is often delayed due to unstable weather conditions, which prolongs the drying process. In addition, the absence of roasting machines means that once the green beans are produced, they have to be roasted in Padang City, which is both time-consuming and costly. The farmers' group has not directly witnessed the coffee processing products consumed by the public, so a comparative study is needed to motivate them to produce high-quality coffee cherries. Therefore, the community service method in this study involves conducting a benchmarking study for the farmers' group to Rimbun Roastery in Padang City, providing short training on coffee cupping and roasting, assisting in the procurement of equipment for coffee drying using coffee husk waste, and the procurement of coffee roasting equipment.. The results of the community service initiative show that the farmers' group has benefited from the coffee taste testing and roasting training activities. The group has also gained an understanding that higher quality coffee commands higher prices, thereby motivating the farmers to produce high-quality coffee. Similarly, the provision of coffee drying equipment and roasting machines has benefited the farmers' group in terms of time and cost efficiency in coffee production. This community service activity has proven to have a positive impact on the Bukik Gompong farmer group.

Abstract

Penelitian ini bertujuan untuk mengevaluasi potensi filter biochar susunan seri dalam menyisihkan detergen dan fosfat dari air limbah artifisial. Filter yang digunakan terdiri atas media biochar dan busa poliuretan dengan perbandingan volume 2:1, disusun dalam dua kolom seri masing-masing setebal 40 cm. Proses filtrasi berlangsung selama 14 hari, dengan konsentrasi awal detergen sebesar 0,701 mg/L dan fosfat sebesar 1,303 mg/L. Hasil penelitian menunjukkan bahwa konsentrasi detergen pada efluen kolom seri 1 dan 2 masing-masing berkisar 0,21-0,43 mg/L dan 0,19–0,33 mg/L, dengan efisiensi penyisihan 39–70% dan 53–72%. Sementara itu, konsentrasi fosfat pada efluen kolom seri 1 berkisar 0,33–0,84 mg/L dengan efisiensi 35–74%, dan pada kolom seri 2 sebesar 0,14–0,66 mg/L dengan efisiensi 49–89%. Penyisihan yang lebih tinggi setelah melewati kolom seri 2 menunjukkan bahwa waktu retensi aliran berperan penting dalam meningkatkan efisiensi penyisihan kontaminan. Secara keseluruhan, penelitian ini menegaskan bahwa filter berbasis biochar berpotensi sebagai media ramah lingkungan untuk pengolahan air limbah yang mengandung detergen dan fosfat.
