This community service initiative aims to apply biopore infiltration hole technology as a community-based flood mitigation solution in Labuhan Ratu District, Bandar Lampung City. This area faces major problems in the form of a high risk of waterlogging caused by low soil absorption, predominance of watertight surfaces, and suboptimal drainage systems. The program is carried out with a project-based community empowerment approach, where as many as 50 local residents are involved in each stage of the activity. These stages include environmental awareness campaigns, technical training on making biopore infiltration holes, providing equipment, and direct practice in the field. A total of 100 strategic points in the Dasawisma Palapa 6 environment are the locations for the implementation of biopores. The results of the activity show that this simple technology effectively improves the soil's ability to absorb water and reduce surface runoff, so that the risk of inundation can be reduced. In addition, this activity also encourages the formation of community groups that are tasked with maintaining biopores, in order to ensure the sustainability of long-term benefits. This program not only has a positive impact on the quality of the physical environment, but also strengthens the capacity of citizens to manage natural resources based on appropriate technology. The active participation of the community has proven to be the key to success, as it creates a sense of belonging while increasing ecological awareness at the local level. These findings confirm that the integration of simple technological innovations and community empowerment is an effective strategy in building sustainable environmental solutions, especially in the face of urban flood challenges.

Household waste management, especially organic waste, remains a major problem in many regions, including Pematang Guntung Village, Teluk Mengkudu District, Serdang Bedagai Regency. Improperly managed organic waste has the potential to cause unpleasant odors, environmental pollution, and become a source of disease. Therefore, an appropriate and environmentally friendly solution is needed to overcome this issue. This study aims to examine how the application of the biopore method can serve as a strategy to create a cleaner environment while simultaneously improving soil fertility. The research method used was qualitative, with data collection techniques including observation, interviews, and documentation. The data obtained were analyzed descriptively to illustrate the implementation of biopores in the community. The results showed that the application of biopores was able to significantly reduce the volume of household organic waste. Organic waste placed into biopore holes naturally decomposed into compost, which is beneficial as an environmentally friendly fertilizer. In addition, biopores improved soil water absorption capacity, which helps reduce waterlogging during the rainy season and maintain soil moisture. From a social perspective, biopores encouraged the development of new awareness among community members regarding the importance of waste management. This was demonstrated by the active participation of residents in creating, utilizing, and maintaining biopore holes sustainably. Thus, biopores function not only as a technical solution for organic waste management but also as an environmental education tool that strengthens community collaboration in maintaining cleanliness and enhancing soil fertility in their area.

Concrete roof tiles are an important material in building construction, particularly for roofing work, due to their advantages in terms of strength, durability, and material availability. This study aims to analyze two main physical characteristics of concrete roof tiles, namely bending load and water absorption, using a literature review approach from various previous studies. Bending load refers to the material's ability to withstand bending forces, while water absorption describes the material's capacity to absorb and store water through its pores. These two properties significantly influence the quality and durability of roof tiles in facing external environmental conditions, especially wet-dry cycles and mechanical loads. The results of the literature review indicate that the use of waste as an aggregate substitute in concrete mixes can significantly improve the performance of concrete roof tiles. For example, research using broken roof tiles and ceramic waste as aggregate substitutes successfully increased flexural strength to a range of 12.5–15.0 MPa. Meanwhile, variations in water absorption were recorded in the range of 4%–8%, depending on the material composition and production method. This proves that the use of recycled materials not only supports sustainability but also improves the mechanical and physical properties of concrete roof tiles. Overall, this study underscores the importance of material innovation in concrete roof tile production, particularly utilizing waste as an alternative aggregate. However, further research is needed to explore the best combination of materials and production techniques for producing high-quality, efficient, and environmentally friendly concrete roof tiles.

Iron deficiency is one of the main causes of anemia, especially in women of childbearing age who have higher iron requirements. Preventive efforts can be done through functional food innovations based on natural iron sources. Beetroot (Beta vulgaris L.) and red spinach (Amaranthus sp.) are known to contain iron in high amounts so they have the potential to be used as alternative raw materials in the manufacture of gluten-free noodles. This study aims to determine the effect of beetroot flour and red spinach flour formulations on the organoleptic properties (color, aroma, taste, and texture) and iron content of gluten-free noodle products. The study used an experimental method with a Completely Randomized Design (CRD) consisting of four treatments: F0 (control), F1 (50:50), F2 (75:25), and F3 (25:75). Iron content analysis was carried out using the Atomic Absorption Spectrophotometry (AAS) method, while the organoleptic test involved 25 untrained panelists who were women aged 15–24 years. The results showed that treatment F3 produced the highest iron content of 12.092 ± 1.658 mg/100 g, while F2 achieved the highest sensory acceptability. Nevertheless, formulation F3 was determined to be the best formulation due to its optimal iron content. This gluten-free noodle product based on beetroot and red spinach has the potential to be developed as a functional food to prevent iron deficiency anemia in women of childbearing age.

The use of organic materials as fertilizers is an important effort to improve soil fertility and crop productivity sustainably. Gliricidia sepium (gamal leaves) is a leguminous plant rich in nutrients such as nitrogen, phosphorus, and potassium, and contains bioactive compounds and microbes that support plant growth. Liquid organic fertilizer (LOF) made from fermented gamal leaves offers advantages including ease of application, high nutrient absorption by plants, and environmental friendliness compared to synthetic chemical fertilizers that may cause pollution and other negative impacts. This study aimed to evaluate the effect of LOF from gamal leaves on the growth and yield of Japanese cucumber (Cucumis sativus L.). The research was conducted at the Experimental Garden of the Faculty of Agriculture, UKI Toraja, South Sulawesi, from April to July 2025. The LOF was produced by fermenting gamal leaves for 15 days using EM-4 solution and palm sugar as activators. The LOF was applied three times at two-week intervals, starting at 7 days after planting (DAP), by soil drenching around the base of the plants. Observed variables included plant height, number of leaves, leaf area, stem diameter, number of fruits per plant and per plot, average fruit diameter and length, and fruit weight per plant and per plot. Data were analyzed using analysis of variance (ANOVA) and the Honestly Significant Difference (HSD) test at a 0.05 significance level. The results showed that application of LOF from gamal leaves at a dose of 300 ml per plant produced the best results across all observed parameters, including plant height, leaf number and area, stem diameter, fruit number, fruit size, and fruit weight per plant and per plot.

Vitamin A Deficiency (VAD) and iron deficiency anemia (IDA) are global nutritional issues affecting children, particularly in developing countries. The interaction between these two conditions can lead to a more complex condition known as Vitamin A Deficiency Anemia (VADA). This study aims to review the molecular relationship between Vitamin A deficiency and iron metabolism leading to VADA, as well as its impact on children's health. The methodology used in this article is a literature review of various clinical studies, epidemiological research, and relevant molecular experiments. The results show that VADA is primarily a functional iron deficiency, where iron absorption is impaired despite overall body iron levels not being critically low. This mechanism involves the regulation of hepcidin, redistribution of iron, and its effects on erythropoiesis. Additionally, therapy with Vitamin A supplementation has been shown to increase erythropoietin and hemoglobin production in children with dual deficiencies. The implications of these findings highlight the need for more integrated therapeutic strategies that consider both Vitamin A and iron status simultaneously. Further research is needed to understand the molecular mechanisms more deeply involved in this interaction and to develop more effective therapies for children with VADA.

Cassava (Manihot esculenta) is a staple food that is widely consumed by the Indonesian population, especially in rural areas. However, during post-harvest handling and storage, cassava is highly susceptible to contamination by microorganisms, particularly fungi. These fungi can cause damage to the food, reduce its nutritional quality, and even produce mycotoxins that are harmful to human health. The increased risk of contamination has become an important concern in efforts to improve the quality and safety of cassava food products. This study aimed to identify the morphology of fungal colonies and the characteristics of fungal cell walls isolated from cassava stored in open environmental conditions for several days. The methods used in this study included isolation using Potato Dextrose Agar (PDA) media, macroscopic observation of fungal colony morphology, including color, edge, elevation, and texture, as well as Gram staining to observe the fungal cell wall properties. The results of this study revealed a diversity of fungal colony morphology, with three dominant types suspected to belong to the genera Aspergillus, Penicillium, and Rhizopus. Gram staining showed that the three isolates were characterized as Gram-negative, indicated by the absorption of safranin as the secondary stain. This study provides an initial overview of the types of fungi that may develop on cassava during storage, and it offers a foundation for further studies on the toxicity and food microbiology applications related to cassava. Morphological identification and Gram staining play an essential role in the initial screening before molecular identification is performed.

Floods are one of the most common natural disasters and have a significant impact on the social, economic, and environmental aspects of society. This is particularly evident in the community of East Sorong District. East Sorong District is one of the areas frequently affected by floods, and this inevitably leads to numerous risks and consequences. There are several causes of flooding in the Sorong Timur District, including extreme rainfall, inadequate drainage systems due to trash blockages, uncontrolled land use changes resulting in overpopulation, and the loss of forest areas or green spaces that could function as water absorption zones. Additionally, the lack of flood control systems and weak oversight of development in flood-prone areas can exacerbate flood disaster risks. This study aims to analyze and measure the resilience of the Sorong Timur District in facing flood disasters through an evaluation approach focusing on infrastructure, service facilities, socio-economic factors, community capacity and preparedness, and institutional aspects. It was concluded that the infrastructure variable is still moderate, while the socio-economic variable, basic capacity, and community preparedness, as well as institutional capacity, are still low. Meanwhile, service facilities are also low. Overall, it can be concluded that the resilience of the Sorong Timur district in facing hydrometeorological disasters is weak.

Data analysis used a dummy variable multiple linear regression model using SPSS (Statistical Program Social Science) version 23. The results of this study indicate that the GRDP variables in the trade, manufacturing and service sectors together have a significant effect on the amount of labor absorption. The Trade Sector Variable partially has a significant positive effect on Total Labor Absorption. The Processing Industry Sector Variable partially has no significant effect on Total Labor Absorption. And the Service Sector Variable partially has a significant negative effect on Total Labor Absorption.

This study investigates the potential of Low-Density Polyethylene (LDPE) plastic waste as a partial substitute for sand in concrete block mixtures, focusing on its effects on compressive strength and water absorption. LDPE is a non-biodegradable plastic waste that poses significant environmental challenges. Its incorporation into construction materials offers a promising solution to reduce pollution while enhancing the performance of building components. The research employed LDPE substitution levels of 10%, 15%, 20%, 25%, and 30% by weight of sand, compared against conventional concrete blocks without LDPE. Experimental results revealed that the highest compressive strength was achieved with a 15% LDPE mixture, reaching 80.762 kg/cm² at 28 days of curing—an increase of approximately 40.8% compared to normal blocks, which recorded 57.359 kg/cm². LDPE additions up to 20% maintained favorable strength characteristics, while higher proportions (25% and 30%) led to a decline in mechanical performance. In terms of water absorption, the inclusion of LDPE demonstrated a decreasing trend, attributed to the hydrophobic nature of plastic, which enhances moisture resistance in the concrete blocks. These findings suggest that a 15% LDPE substitution represents an optimal formulation for producing eco-friendly concrete blocks with improved strength and reduced water absorption. The study highlights the dual benefits of waste management and material innovation, aligning with sustainable development goals. By repurposing plastic waste into construction applications, this approach not only mitigates environmental impact but also contributes to the advancement of green building technologies. Further research is recommended to explore long-term durability, thermal properties, and scalability of LDPE-based concrete products in real-world construction settings.

This study investigates the influence of economic growth, investment, and minimum wage on the open unemployment rate across districts and cities in East Kalimantan Province. The research employs a quantitative descriptive approach with panel data regression analysis, processed using EViews 13 software. Model selection was carried out through the Chow and Hausman tests, which identified the Fixed Effect Model (FEM) as the most appropriate estimation technique. The study utilizes secondary data from 2018 to 2024, obtained from the Central Bureau of Statistics (BPS) and the Investment and One-Stop Integrated Service Office of East Kalimantan Province. The empirical findings demonstrate that economic growth exerts a negative and statistically significant impact on the open unemployment rate, indicating that higher economic growth effectively contributes to reducing unemployment in the region. Foreign Investment (PMA) is found to have a negative but insignificant effect, suggesting that inflows of foreign capital alone do not directly translate into job creation unless accompanied by supporting policies and local labor absorption capacity. In contrast, Domestic Investment (PMDN) shows a positive yet statistically insignificant relationship with unemployment, reflecting the possibility that domestic investments may not always generate sufficient employment opportunities in the short term due to structural constraints or sectoral imbalances. Furthermore, the minimum wage variable has a negative and significant effect on the open unemployment rate, implying that increases in the regional minimum wage can stimulate greater employment absorption and improve labor market conditions. Overall, the results highlight the importance of fostering sustained economic growth and designing investment policies that are more labor-intensive to optimize employment creation. Additionally, the findings emphasize the strategic role of minimum wage policy in supporting job opportunities while safeguarding workers’ welfare.

Trace elements such as copper, zinc, selenium, and chromium play essential roles in various enzymatic reactions, antioxidant defense mechanisms, and overall metabolic regulation, making them crucial for maternal and fetal health. During pregnancy, the demand for these micronutrients increases significantly due to physiological changes and the needs of the developing fetus. Inadequate or excessive levels of these trace elements can lead to altered fetal development and may impact neonatal outcomes immediately after birth. Given the sensitive developmental window of gestation, the intrauterine environment—including micronutrient status—has been hypothesized to influence neonatal physiological parameters such as heart rate, respiratory rate, and Apgar scores, which are commonly used to assess neonatal wellbeing in the early minutes of life. This study attempts to explore the impact of maternal trace element status—specifically copper, zinc, selenium, and chromium—along with selected maternal parameters (BMI, parity, gravida) on indicators of neonatal wellbeing, including heart rate, respiratory rate, and 5-minute Apgar score. A cross-sectional study was conducted in the Delivery Room of the Obstetric Hospital in Al-Diwaniya City, Iraq, involving 50 mother-infant pairs. Data collection occurred from December 1, 2024, to February 10, 2025. Maternal blood samples were analyzed using atomic absorption spectrophotometry to determine serum concentrations of copper, zinc, selenium, and chromium. Neonatal outcomes were assessed via standard clinical evaluations: heart rate and respiratory rate were measured immediately postpartum, and Apgar scores were recorded at five minutes. Statistical analyses included Pearson correlation and multiple linear regression to assess associations between maternal factors and neonatal outcomes. Bivariate and multivariate analyses indicated limited but noteworthy associations. Maternal serum chromium levels were significantly associated with increased neonatal respiratory rate (p = 0.026), suggesting a possible stimulatory or stress-related effect.

This community service activity was carried out in Dahu Village, Pandeglang Regency, with the main objective of introducing and implementing biopore infiltration hole technology as a simple and environmentally friendly solution to address waterlogging and organic waste management. Biopores are small-diameter vertical holes dug into the ground and then filled with organic waste, such as dry leaves, vegetable scraps, or food scraps. This organic waste will naturally decompose through a decomposition process, producing compost that is useful for fertilizing the soil. Furthermore, the presence of biopore holes can improve the groundwater absorption capacity, thereby reducing the risk of waterlogging and minor flooding around residential areas. During the implementation, we as students not only provided theoretical explanations through socialization sessions but also actively participated directly in the field. Together with residents, we practiced making biopore holes, starting from the stages of preparing tools and materials, the process of drilling the soil, and filling the holes with organic waste. This practical activity was designed to help the community understand the steps for making biopores independently and utilizing them sustainably. The results of the activity showed an increase in community understanding and awareness of the importance of easy, affordable, and beneficial waste management. The community is beginning to realize that waste processing does not always require large costs or complicated technology. Biopore holes have been proven effective in accelerating rainwater absorption, reducing household waste volume, and improving soil fertility. Beyond the environmental impact, this activity also strengthens relationships between students and villagers through the collaboration established during the biopore construction process. Thus, this program is expected to be the first step towards a cleaner, healthier, and more sustainable village.

The data used in this research are secondary data obtained from the Revenue Department, the Central Bureau of Statistics (BPS) in the Sarbagita Regional Area, and the Central Bureau of Statistics (BPS) of Bali Province. The analytical tool used in this study is path analysis with the assistance of SPSS software. The results indicate that DAK does not have a positive and significant effect on employment absorption in the Sarbagita region. Investment has a positive and significant effect on employment absorption. Employment absorption has a negative and significant effect on poverty levels in the region. DAK does not have a significant effect on poverty through employment absorption, whereas investment does have a significant effect on poverty through employment absorption in the Sarbagita region.

The management of blood glucose levels in individuals diagnosed with diabetes mellitus is a multifaceted process that involves the integration of pharmacological therapy and evidence-based nutritional interventions. Among these strategies, nutritional therapy plays a pivotal role in achieving optimal glycemic control and preventing diabetes-related complications. The success of nutritional therapy is closely tied to the individual’s adherence to prescribed dietary guidelines and the ability to meet adequate protein intake as recommended by healthcare providers. Protein is essential not only for maintaining muscle mass and supporting metabolic functions but also for its role in stabilizing blood glucose levels through slower glucose absorption and enhanced satiety. This study was conducted to investigate the relationship between dietary adherence and adequate protein intake with fasting blood glucose (FBG) levels among outpatients diagnosed with type 2 diabetes mellitus at RSUD dr. Iskak Tulungagung. A quantitative research method with a cross-sectional design was employed, involving 26 respondents selected using a non-probability sampling technique. Data collection utilized structured questionnaires to assess dietary compliance, interview forms to capture dietary behavior and protein intake patterns, and medical record documentation to obtain accurate FBG measurements. Statistical analyses included Pearson correlation tests for normally distributed data and Spearman rho tests for non-normally distributed data, ensuring appropriate analytical rigor. The results indicated a significant negative correlation between both dietary adherence and adequate protein intake with fasting blood glucose levels. This finding suggests that individuals who consistently follow dietary recommendations and consume sufficient protein tend to exhibit lower FBG values, indicating better glycemic control. Such results underscore the importance of not only emphasizing dietary compliance but also ensuring protein adequacy in daily nutritional plans for type 2 diabetes patients. These findings have practical implications for diabetes management programs, highlighting the necessity of sustained patient education, regular counseling, and individualized meal planning.

Excessive fat consumption can lead to increased cholesterol levels in the body, which in turn can trigger various serious health problems, including heart disease, blood vessel blockage, and even stroke. Blood cholesterol consists of two main types: LDL (Low-Density Lipoprotein) cholesterol, often referred to as bad cholesterol, and HDL (High-Density Lipoprotein) cholesterol, which plays a role in transporting cholesterol from the blood vessels to the liver for excretion. Elevated LDL cholesterol levels can cause plaque buildup on blood vessel walls, which narrows blood flow and increases the risk of various cardiovascular diseases. One method considered effective for lowering LDL cholesterol levels in the blood is by consuming phytosterols, compounds found naturally in various types of plants. Phytosterols have a structure similar to cholesterol and can compete with cholesterol for absorption in the intestine. This results in a decrease in the amount of cholesterol entering the body, thereby reducing total cholesterol levels and especially LDL cholesterol in the blood. Research shows that giving food or supplements containing about 3 grams of phytosterols per day to human subjects can reduce LDL cholesterol levels by up to 15%. Furthermore, phytosterols directly isolated from plants, such as green beans, have also been shown to significantly lower LDL cholesterol levels. Studies in mice fed phytosterols isolated from green beans showed a reduction in blood LDL cholesterol levels of more than 30%. This demonstrates the potential of phytosterols as a natural ingredient that can be used to support cholesterol management in the body. Although phytosterols have significant potential in lowering cholesterol levels, it is important to remember that consuming supplements or foods containing phytosterols should be done under the supervision and recommendation of a medical professional, especially for individuals with certain medical conditions or who are taking medications.  

This study aims to determine the effect of adding EM4 probiotics in various doses to commercial feed on the growth of jatimbulan tilapia (Oreochromis niloticus L). Probiotics are known to play a role in increasing digestive efficiency, nutrient absorption, and maintaining the health of the fish's digestive tract, so they are expected to support optimal growth. The research method used was a Completely Randomized Design (CRD) with four treatments, namely: P0 (control/without probiotics), P1 (5 ml EM4/kg feed), P2 (7 ml EM4/kg feed), and P3 (11 ml EM4/kg feed), each with four replications. The parameters observed were the growth in length and weight of jatimbulan tilapia during the maintenance period. The results showed that the administration of EM4 probiotics at certain doses was able to provide a significant effect on the growth of tilapia compared to the control treatment. Treatment P2 (7 ml/kg feed) provided the best growth results compared to other doses, both in terms of increasing length and body weight. Meanwhile, administering probiotic doses that are too low (P1) or too high (P3) tends to be less effective in supporting optimal growth. This is thought to be due to the disruption of the microbial balance in the digestive tract when the probiotic dosage is incorrect. This research provides useful information for Jatimbulan tilapia cultivation practices, particularly regarding the use of probiotics to increase growth efficiency. Using the correct probiotic dosage can be a strategy to increase the productivity and sustainability of freshwater fish farming.
