Abstract

The COVID-19 pandemic has introduced significant behavioral changes driven by adopting health protocols known as the 5M measures—mask-wearing, handwashing, maintaining physical distance, limiting mobility, and avoiding crowds. This study evaluates the implementation of the 5M health protocols in Trenggalek and Bendungan Districts, representing urban and rural areas, respectively. Utilizing the Unified Theory of Acceptance and Use of Technology (UTAUT) model, modified with Clean and Healthy Behavior (PHBS) constructs, this research examines community awareness and adherence to 5M protocols. A survey involving 758 respondents from both districts was conducted during the pandemic to assess factors influencing compliance. The findings highlight that social influence through counseling, advertisements, and posters plays a pivotal role in shaping behavioral intentions related to protocol adherence. Furthermore, these intentions directly influence actual behavior, reinforcing sustained compliance with the 5M measures. Notably, urban and rural contexts demonstrated similar patterns, underscoring the universal impact of social influence regardless of geographic setting. This study concludes that strengthening community engagement and targeted social campaigns can enhance public health resilience and preparedness for future pandemics by fostering sustainable health-conscious behavior.

Abstract

The rapid development of technology in Indonesia significantly impacts various aspects of life, including the industrial sector. One of the negative impacts on this sector is the occurrence of work accidents that cause injury and death. This is due to the low implementation of Occupational Health and Safety (K3) culture in the industrial world. PT XYZ, a company engaged in the hot rolling coil industry in Sidoarjo, implements a K3 system. However, based on initial observations, there are still obstacles, especially the lack of understanding of human resources regarding Standard Operating Procedures (SOP). This study aims to identify the factors causing work accidents and outline corrective steps to reduce the risk. Using the Job Safety Analysis (JSA) method, this study found that in 2022, there were 43 cases of work accidents, while in 2023, the number decreased to 41 cases. As a result of these accidents, in 2022, there was a loss of 21 working days per 1,000,000 working hours/person, while in 2023, the loss of working days decreased to 18 days for the same period. The accident indicator also showed a decline, from 0.47 in 2022 to 0.38 in 2023. Recommendations to prevent work accidents at PT XYZ include reading the safety board, attending briefings before work, doing work according to the job description, and using personal protective equipment such as safety shoes and work helmets.

Abstract

This study aims to determine the best composition related to the proportion of wheat flour and mocaf in processing crispy ginger and developing gluten-free food products. The study used factorial experiments with the first factor being proportion of mocaf and wheat flour (P1) consisting of three treatment levels are P1 (mocaf: wheat flour= 50:50), P2 (mocaf: wheat flour= 75:25), and P3 (mocaf: wheat flour= 100:0). The second factor was the concentration of ginger extract (J), consisting of three treatment levels are J1 (ginger extract concentration 20%), J2 (ginger extract concentration 30%), and J3 (ginger extract concentration 40%). The results of the study showed that the proportion of mocaf and wheat flour decreased protein, fat, and water content, but increased carbohydrate and antioxidant content in the crispy ginger. The concentration of ginger extract increased protein, fat, water, and antioxidant content but decreased carbohydrate content in the crispy ginger. Organoleptic testing showed that colour, aroma, taste, and texture were undesirable. The findings of this study indicate that the production of crispy ginger has potential, but improvements are needed for colour, aroma, taste, and texture parameters. The selected treatment alternative was the P2J2 treatment.

Abstract

The manufacturing industry faces many challenges in continuing to compete with its competitors. These challenges come from various aspects, namely economic, social, and environmental. One approach to fixing this problem is to use effective SCOR, AHP, and OMAX methods. PT XYZ is a sugar company that has never measured sustainable supply chain performance. In connection with this, many studies have measured the performance of the sustainable supply chain. This research aims to improve the performance of Sustainable Supply Chain Management (SSCM) in production activities carried out by PT. XYZ so that the production process runs well and still pays attention to the sustainability aspects that must be implemented. A total of nineteen key performance indicators (KPIs) were generated by the five SCOR models used in data processing (plan, source, make, deliver, and return). There are seventeen key performance indicators with green indicators and two yellow indicators. With a final score of 8,022 on the sustainable supply chain performance level, this value is included in the green category which shows the company has successfully implemented the concept of sustainability in its business line.

Abstract

Indonesia is a country with the highest biodiversity, especially in mangrove ecosystems, with a total of around 89 species. The mangrove ecosystem includes Rhizophora (mangrove), Avicennia (api-api), Sonneratia (pedada), Bruguiera (tanjang), and Xylocarpus (nyirih). Mangrove propagules are the fruits of mangroves in the form of hypocotyls that function to store food when the propagules germinate and grow. Secondary metabolites from plants have bioactivity, so it is important to identify them using specific reagents known as phytochemical screening. The group of secondary metabolite compounds is classified based on their chemical structure, consisting of flavonoids, tannins, phenols, alkaloids, steroids, and triterpenoids. This study aims to determine the content of flavonoid, tannin, and phenol compounds in Bruguiera sp. propagules. The method for extracting tannins, phenols, and flavonoids from mangrove propagules can be performed using the Microwave Assisted Extraction (MAE) method. The raw material is 3 kg of Bruguiera sp. mangrove propagules from Kutawaru Village, which are then cut into small pieces and dried using an oven at 105°C for 3 hours, subsequently ground, and sieved with a 60 mesh size. The extraction process of the mangrove propagule powder was weighed at 15 grams using 250 ml of ethanol as the solvent. The results of the phytochemical test on the Bruguiera sp. mangrove propagule extract were positive for flavonoids, tannins, and phenols.
