Abstract

Introduction: The incidence of malaria infection is influenced by several factors, including micronutrient intake. Micronutrient intake is essential for maintaining normal nutritional status and maintaining a healthy immune system. Vitamin A, zinc, and iron are micronutrients that function to boost the immune system. This study aims analyze the relationship between micronutrient intake and the incidence of malaria infection at the Paguat Community Health Center.Method: This study used a cross-sectional study method with an analytical observational approach. The population in this study consisted of 37 people obtained from the medical records of the Paguat Community Health Center for the period January-July 2025, using total sampling techniques. The study used primary data in the form of questionnaires and 3x24-hour food recall interviews. The 3x24-hour food recall method was calculated using the Nutrisurvey application to determine the nutritional content of each food item. Data analysis was performed using univariate, bivariate, and multivariate methods.Results: Bivariate analysis showed that micronutrient intake such as vitamin A (P-value = 0.680) and iron (P-value = 0.080) had no significant association with malaria infection. Meanwhile, zinc micronutrient intake (P-value = 0.030) had a significant association with malaria infection. Based on multivariate analysis, P-value of 0.025 (P 0.05) was obtained, with a confidence interval (95% CI: 0.035–0.798). Zinc micronutrient intake has a significant effect on the incidence of malaria infection.Conclusion: The analysis shows no statistically significant relationship between vitamin A and iron intake with malaria infection. Zinc intake is statistically significantly associated with malaria infection. Keywords: Anopheles sp., malaria, nutritional status, Plasmodium sp.

Abstract

The use of skincare products among teenagers is increasing alongside the growing trend of beauty, the influence of social media, and the need to maintain appearance and skin health. However, the high level of interest among teenagers in skincare is not always accompanied by adequate knowledge of cosmetic safety, particularly in identifying products containing harmful ingredients such as mercury. The purpose of this community service activity is to raise awareness of safe and mercury-free skincare products through education on cosmetic safety. The target audience for the activity is 32 SMKN 1 Boalemo students. The method of implementation involves the delivery of materials by the speaker on the subject of skincare for teenagers that is free of mercury, the dangers of mercury to health, the importance of BPOM approval, reading product labels, and critical thinking about cosmetic claims. The activity continued with a question-and-answer session and a practical demonstration through a video of cosmetics containing mercury and their impact on health. The results of the activity show that education on mercury-free skincare contributes to increasing students’ knowledge and understanding regarding the importance of choosing skincare products that are safe, legal,suited to their skin’s needs, and not easily swayed by viral products or claims of rapid skin whitening. Visual media, such as informational materials and practical demonstration videos, helped participants understand the risks of mercury-containing cosmetics in a more concrete way. This activity serves as a preventive measure to shape high school students into more critical, informed, and responsible teenage consumers when using skincare products. Thus, mercury-free skincare education is essential in school settings to strengthen cosmetic safety literacy from a young age.

Abstract

Thermochemistry is frequently regarded as difficult because students must connect observable heat phenomena, particle-level energy changes, and symbolic enthalpy calculations. This study aimed to analyze students’ thermochemistry concept understanding based on the consistency of their answers using a parallel three-tier diagnostic test. The research used a descriptive qualitative approach at SMA Negeri 1 Kabila during the odd semester of the 2025/2026 academic year. The subjects were 135 grade XI students. The instrument consisted of 20 parallel three-tier multiple-choice items arranged in 10 pairs that measured the same concepts through answer choices, reasoning choices, and confidence levels. Instrument quality was examined through expert validation and empirical testing using the Rasch model. The data were analyzed by calculating answer consistency and classifying students into knowing concept, misconception 1, misconception 2, misconception 3, and not understanding concept categories. The results showed that the average consistency of students’ concept understanding was only 29.48%, whereas inconsistency reached 70.52%. The average knowing concept category was 51.19%, followed by misconception 1 at 11.19%, misconception 2 at 16.84%, misconception 3 at 10.04%, and not understanding concept at 10.85%. These findings indicate that students’ thermochemistry understanding was not yet stable, especially for Hess law, calorimetry, and bond energy concepts.

Abstract

Occupational accidents in the coconut flour industry in Gorontalo Regency remain a serious threat to workers, with an increasing incidence rate and a high risk of causing permanent disability. This study aims to analyze the risk factors for work-related accidents leading to disability among workers in the coconut flour industry of Gorontalo Regency. This research is a qualitative study utilizing a case study approach. Data collection was conducted through in-depth interviews, field observations, and documentation. The informants consisted of workers with disabilities resulting from occupational accidents, the person in charge of the Occupational Health and Safety Management System (OHSMS), and OHS practitioners. Data analysis was performed using the Miles and Huberman model. The results indicate that accidents leading to disability are dominated by the sheller unit. These incidents are triggered by the interaction between unsafe actions and unsafe conditions. Behavioral factors include low OHS knowledge, rushed work attitudes to meet production targets, and non-compliance with the use of standardized Personal Protective Equipment (PPE). These conditions are exacerbated by substandard physical work environments, characterized by high room temperatures (32.3°C–33.7°C) and dim lighting (132–176 Lux), which significantly reduce worker concentration. Furthermore, the suboptimal implementation of OHSMS policies and management supervision increases the risk of fatalities.

Abstract. Rumape O, Kilo A, Ischak NI. 2022. Amethyst leaf extract as pest control and fertilizer for soybean plants. Biodiversitas 23: 3355-3363. Amethyst (Datura metel L.) is a plant that grows and develops in the Gorontalo area, and people use it as traditional medicine. This plant has a natural insecticidal activity that is not yet known by the general public. So far, the results of research on natural insecticides from amethyst have only been tested on a small scale in the laboratory, not yet applied on a large scale in the garden. The purpose of this study was to extract amethyst leaves and apply it as an inhibitor of feeding activity and insect mortality in both the laboratory and soybean gardens. Amethyst leaves were extracted in the laboratory using methanol, n-hexane, and ethyl acetate. The extracts were tested phytochemically to determine the type of secondary metabolite, before applying it. Phytochemical test showed amethyst leaves contain alkaloid, flavonoid, terpenoid, and saponin. The application treatment for the bioactivity used variations in the concentration of amethyst leaf extract of the fractions (methanol, ethyl acetate and n-hexane), namely 1.0, 2.5, 5.0, 7.5, 10%; and 0% as control. In the laboratory, the treatment was applied by contact to 5 insects Spodoptera litura instar III for each concentration treatment with 3 replications. Observation parameters were the percentage decrease in feeding activity and mortality of Spodoptera litura larvae. In the garden, the extracts with varying concentrations of the same as in the laboratory, were applied to soybeans treated with the pest Spodoptera liturain a closed container, and the other was sprayed on plants that were left exposed. The results showed that the three extracts could kill pests, but n-hexane extract was the most effective compared to ethyl acetate and methanol extracts. Amazingly, soybean plants whose yellow leaves turn green after being given the extract. This indicates that the secondary metabolites of amethyst are not only used as insecticides to control pests, but also as plant fertilizers.

Abstract

This study aimed to develop a Higher Order Thinking Skills (HOTS)-based formative test instrument on chemical equilibrium material and to analyze the quality of the instrument based on validity, reliability, difficulty level, discrimination power, and distractor effectiveness using the Rasch Model. This study employed a Research and Development method involving 564 students as research subjects. The developed instrument consisted of HOTS multiple-choice questions at cognitive levels C4, C5, and C6. Instrument validity was analyzed through expert validation, while empirical analysis was conducted using Winsteps and Microsoft Excel. The results showed that the instrument obtained a validity percentage of 88.95%, categorized as very valid. Rasch Model analysis indicated that all items met the item fit criteria with a Cronbach Alpha reliability value of 0.78, categorized as good. The item difficulty levels consisted of easy, moderate, and difficult categories, with moderate items being dominant. All items demonstrated good discrimination power as indicated by positive Pt Measure Corr values. In addition, most distractors functioned effectively because they were selected by students. The distribution of HOTS items consisted of 44.44% C4 level, 33.33% C5 level, and 22.22% C6 level. Therefore, the HOTS-based formative test instrument on chemical equilibrium material was considered feasible for measuring students’ higher-order thinking skills.
