Abstract

Sampah yang tidak dikelola dengan baik dapat merusak dan mencemari lingkungan. Pembuatan kompos menjadi salah satu metode pengelolaan sampah organik yang dapat dilakukan pada tingkat rumah tangga. Penelitian bertujuan menganalisis pengaruh variasi campuran serbuk kayu, sampah sayuran dan kotoran kerbau terhadap waktu pengomposan dan kadar C-organik, Nitrogen total, Phosfor, Kalium (CNPK) kompos. Penelitian Quasi Experiment dengan rancangan Post Test Only Desain. Percobaan dilakukan dengan tiga variasi perlakuan (komposisi tiga jenis bahan) yang ditentukan berdasarkan C/N rasio awal, yaitu 30:1, 35:1, dan 40:1. Keseluruhan percobaan dilakukan dengan lima kali pengulangan (n= 15). Pengukuran pH dan suhu dilakukan selama percobaan dan dihentikan setelah mendapatkan tingkat kematangan kompos yang diinginkan (dinilai dari warna, bau, dan tekstur kompos), selanjutnya dianalisis kadar CNPK. Data dianalisis dengan uji Manova (Multivariate Analysis of Variance) untuk mengetahui perbedaan bermakna dari variasi perlakuan terhadap lama waktu pengomposan dan kadar CNPK, pada tingkat kepercayaan 95%. Hasil penelitian menunjukkan pengaruh variasi campuran perlakuan terhadap waktu pengomposan dan kadar CNPK kompos (P < 0,05). Dari tiga variasi, perlakuan ketiga (40:1) menunjukkan hasil terbaik dengan lama waktu pengomposan selama 16 hari, serta kadar NPK yang memenuhi standar yang ditetapkan (N= 1,19%, P= 0,4%, dan K= 2,32%). Namun, ketiga perlakuan mendapatkan kadar C-organik melebihi standar yang ditetapkan (> 32%). Percobaan telah membuktikan pengaruh variasi campuran serbuk kayu, sampah sayuran dan kotoran kerbau terhadap waktu pengomposan dan kadar CNPK kompos. Keseragaman jenis kayu serta penurunan kuantitas serbuk kayu menjadi rekomendasi penelitian selanjutnya.

Abstract

The cleanliness of the hands of food handlers is a major factor in preventing the spread of disease. The study aims to analyze the effect of using starfruit juice hand sanitizer on the bacteria in the hands of food handlers. The study used a Pretest Posttest with a Control Group Design, conducted in Yogyakarta from March to May 2024. The study involved 24 food handlers. The study used starfruit juice as the basic ingredient for hand sanitizer in three concentration variations (25%, 30%, and 35%). Sampling of hand bacteria was carried out before and after each treatment using the swab method, then incubated for 24 hours at 37°C. Data were analyzed using the Shapiro-Wilk test, One Way ANOVA, and Tukey HSD with a confidence level of 95%. The study results found that starfruit juice hand sanitizer can reduce the number of hand germs (P = 0.001). A concentration of 25% was able to reduce 65.06% (2.29 x 104 to 8.22 x 104 CFU/cm2), a concentration of 30% reduced 69.79% (from 2.09 x 104 to 6.15 x 104 CFU/cm2), and a concentration of 35% reduced up to 85.53% (from 2.72 x 104 to 3.99 x 103 CFU/cm2). The study results also found that more than 85% of respondents liked the color, smell, viscosity, and texture of the hand sanitizer. In addition, the hand sanitizer did not change even though it was stored for up to 28 days (12-140C). Star fruit has the potential to be used as a basic ingredient for making hand sanitizers. In addition to being easy to obtain and cheap, hand sanitizers made from star fruit juice have been proven to be effective as antiseptic.

Abstract

Groundwater serves as the primary source of potable water globally, including in Indonesia. Unfortunately, the presence of fluoride concentrations in groundwater, whether in ideal, insufficient, or excessive quantities, can have either beneficial or detrimental effects. Presently, the inhabitants of Jakarta persist in relying on groundwater as their primary source of clean water, which presents an escalating peril to public well-being as a result of increased domestic activities. Regarding the situation, this research aims to analyze the temporal trends and spatial distribution of fluoride concentration in groundwater and its potential consequences for public health risks in Jakarta. A total of 1,418 fluoride and temperature data from the Jakarta Environmental Agency was used for spatial-temporal analysis of 2016–2019 trends. We applied Microsoft Excel 2021 and ArcGIS Pro 3.2 for statistical and spatial data analysis. The result indicated that the fluoride concentration in groundwater was 72.14% below the minimum recommended value of 0.5 mg/L, mostly in the southern part of Jakarta. However, the average fluoride concentration for all seasons per year is consistently increasing, specifically in the northern part of Jakarta. Based on this research's findings, we concluded that the deficiency of fluoride concentration in groundwater is the majority problem in Southern Jakarta and could potentially cause dental caries if the groundwater is used as the daily source of clean water. This information is very useful for the government and public health authorities to further mitigate and protect people in Jakarta who still rely on groundwater as the source of clean water.

Abstract

The microbiological quality of indoor air is still a signifikans concern because it causes mortality and morbidity. This study aims to analyze the effect of green betel leaf extract (Piper betle L.) on reducing the bactherial in the air. Quasi-research using the One Group Pretest Posttest design, conducted in March-May 2024. Betle leaves were extracted using the maceration method using 96% Ethanol solvent, then diluted with distilled water to obtain a concentration of 15%. Three volume variations (0.5 ml, 1.0 ml, and 1.5 ml) were put into a humidifier and applied to a nine-square-meter bedroom for three hours, with six replication. Sampling was carried out before and after the experiment. All data (N= 48) were analyzed using the One Way ANOVA and Tukey tests at CL 95%. The study results found a decrease in colonies in the treatment with a volume of 1.0 ml and 1.5 ml: 39.3% (from 36.2 to 22.3 CFU /m3) and 17.6% (from 49.2 to 37.0 CFU /m3). The treatment with a volume of 0.5 ml did not show a decrease. The statistical analysis showed a significant effect of betle leaf extract on reducing the bacteria in the air (P= 0.020). The study results have proven that green betle leaf extract can be used as a disinfectant to reduce the bacteria in the air. However, safe use must be applied by paying attention to the air humidity level.

Abstract

Tofu industry workers are at risk of experiencing Low Back Pain (LBP)   because they work with heavy loads and risky work postures for a continuous period of time. The study aims to analyze the relationship between work posture, work period, and knowledge with LBP.: Descriptive analytical research with a cross-sectional design, conducted in Palembang City from March to April 2024. The study involved 40 participants. Data collection was carried out by observation and interviews. Work posture was assessed using the Rapid Entire Body Assessment (REBA) method, while the variables of length of service, knowledge, and LBP   were obtained from interviews. All data were analyzed using the Chi-Square test and Prevalence Odds Ratio (POR) at a 95% confidence level. The study found that 17 (42.5%) respondents experienced LBP, 13 (32.5%) had risky work postures, and 22 (55%) respondents had a work period of 6-10 years. The analysis results found that there was a significant relationship between work posture (P= 0.007) and work period (P= 0.010). At the same time, knowledge did not show a significant relationship with LBP   (P= 0.167). Risk factors for LBP in tofu industry workers are work posture (POR= 9.524) and work period (POR= 9.750). The study results found that LBP is closely related to work posture and work period. Muscle stretching, getting enough rest, and using ergonomic work tools are research recommendations.

Abstract

Disposing of domestic waste into the river remains a common practice among the majority of residents along the Kahayan River in Palangka Raya City impacting pollution, flooding, and public health. This study aims to analyze variables influencing people's intention to support domestic waste management activities. The study was conducted in Mendawai and Flamboyan Bawah, densely populated settlements on the banks of the Kahayan River in Palangka Raya City. One hundred respondents were selected with a non-probability technique and interviewed to obtain information on infrastructure (X1), economy (X2), location (X3), institutions and regulations (X4), and waste management information (X5) aspects. Descriptive statistics was utilized to understand respondent characteristics and Structural Equation Model-Partial Least Square (SEM-PLS) was applied to determine the effect of each variable. This study found that the majority of respondents were women (n = 44), housewives (n = 40), and over 35 years old (n = 46). The analysis results show that increasing the information aspect of waste management will increase the community's intention to support domestic waste management activities by 40.1% (P = 0.001). Meanwhile, increasing the institutional and regulatory aspects has an effect of 29.2% (P = 0.002). The other three variables did not show significant results (P > 0.05). The results of this study reveal that the community's intention to support domestic waste management activities is influenced by the informational, institutional and regulatory aspects. Establishing community-based institutions that able to provide ongoing support presents a viable strategy for promoting sustainable behavioral change.

Abstract

Stunting among infants and toddlers in Sungai Landas Village, Banjar Regency, remains above the national target. Access to clean water and healthcare services plays a crucial role in preventing stunting, but the relationship between these two factors in this area has not yet been studied simultaneously. The study aim to analyze the association between access to clean water and access to healthcare services with the incidence of stunting among children under five in Sungai Landas Village. A quantitative cross-sectional study was conducted involving 30 children under five selected through purposive sampling. Data were obtained using an adapted Indonesian Nutritional Status Survey (SSGI) questionnaire, which assessed water source quality and the frequency of access to healthcare services. Stunting status was determined by measuring height-for-age according to Regulation of the Minister of Health No. 2 of 2020. Bivariate analysis was run with Fisher’s Exact test to assess the association between access to clean water and healthcare services and stunting incidence. Bivariate analysis revealed no significant association between access to clean water and stunting (p = 0.267), nor between access to healthcare services and stunting (p = 0.469). There is no significant association between the type of drinking water source or the frequency of healthcare service access and stunting among children under five in Sungai Landas Village. Other factors, such as a balanced diet and hygienic practices, also play a role. Recommendations include strengthening education on water treatment and family nutrition, improving the quality of healthcare services, and implementing multisectoral programs for more effective stunting reduction.

Abstract

Considering the highly detrimental future impacts of stunting, a risk map is needed. It will serve as a basis to design stunting control strategies. This study aims to determine stunting risk areas by combining the Analytical Hierarchy Process (AHP) and Geographic Information System (GIS). This study used ecological design, with a case being studied was Pesawaran Regency, Lampung Province. All secondary data were aggregate, and used sub-districts as spatial boundaries. Study variables comprised access to safe drinking water, healthy sanitation, exclusive breastfeeding, complete immunization, diarrhea, number of health facilities, fourth visit during pregnancy (ANC-K4), and child growth and development monitoring. The map was developed by employing Weighted Sum Overlay (WSO) technique. Determining weights involving multiple criteria was conducted by using AHP. The AHP yielded weighted values for each variable, namely exclusive breastfeeding (22.9%), ANC-K4 (14.4%), monitoring of child growth and development (11.7%), access to safe drinking water (11.0%), diarrhea (10.8%), number of health facilities (10.1%), complete basic immunization (10.1%), and healthy sanitation (9.0%). WSO technique revealed that three out of eleven sub-districts were included in the high-risk category for stunting (Tegineneng, Kedondong, and Padang Cermin). Meanwhile, the remaining areas were included in the medium category (Way Khilau, Marga Punduh, and Punduh Pedada) and low category (Negara Katon, Gedong Tataan, Way Lima, Way Ratai, and Teluk Pandan). GIS and AHP methods were applied to determine stunting risk areas. Areas with a high risk of stunting category are Tegineneng, Kedondong, and Padang Cermin. Suggested fundamental programs to control stunting are improvement in exclusive breastfeeding, ANC-K4 visit, monitoring of children growth and development, access to drinking water, and prevention of diarrhea.

Abstract

Oil palm shells are solid waste generated from the palm oil industry. The processing of oil palm shells into activated charcoal has not yet been optimized, despite the high demand for activated charcoal in various industries, such as desulfurization in gas purification and LNG processing, as well as filtration processes. Therefore, the quality of activated charcoal depends on the carbonization and activation process. This study aims to determine whether oil palm shells can be converted into activated charcoal using H₃PO₄ as an activating agent at concentrations of 8%, 9%, and 10%, and soaking times of 20, 22, and 24 hours, by the Indonesian National Standard (SNI) for activated charcoal. This study employs a pre-experimental, one-shot case study design. The treatment applied includes the independent variables of H₃PO₄ concentrations (8%, 9%, 10%) and soaking durations (20, 22, 24 hours). The carbonization temperature for all samples was 450–500°C for 0.5 hours. The dependent variable is the resulting activated charcoal powder that meets SNI standards. Activated charcoal with an 8% H₃PO₄ concentration and a 20-hour soaking time yielded the following results: a moisture content of 10.64%, an ash content of 2.66%, and a calorific value of 3,678.43 cal/g. With 9% H₃PO₄ and 20-hour soaking: 9.88% moisture, 2.95% ash, and 4,955.1 cal/g. With 10% H₃PO₄ and 20-hour soaking: 8.21% moisture, 3.53% ash, and 6,190.58 cal/g. The best result, according to SNI 1683-2021 "Wood Charcoal", was achieved at 24 hours of soaking and a 10% H₃PO₄ activator concentration, with the following values: 8.21% moisture, 3.53% ash, and 6,190.58 cal/g calorific value. It is therefore recommended for activated charcoal production.
