Websites are usually used as a means of conveying or searching for information, for example in the field of borrowing library books. In the development of technology, students are not enough just to be users but must understand more or less how to create websites. Currently, the Medan 4 Methodist school has never implemented practical learning in creating websites, they have only studied Microsoft Office. With the development of technology, schools should have introduced ways of creating websites at the high school level which can later be applied to the school environment and outside the school environment. After holding discussions with the Medan Methodist 4 High School, they needed a complete briefing on the basics of creating a website. This Community Service is a solution to answer the challenges posed by the Medan 4 Methodist High School. This service will provide training to several high school students to become proficient in creating websites. The priority issues include improving skills in website applications, creating students who are skilled in creating website applications. This training can increase students' knowledge regarding creating library websites which can later be improved to create a book lending website at the Medan 4 Methodist School library. This should be overcome with a website-based library information system, because with a website-based information system library data management can be more effective so that the circulation of book loans can be well documented and more effective. With this training, students will be able to contribute a website to the school as their creation.

Assessment of building conditions is a method of evaluating a building objectively in the form of a scale of 1-100 based on the performance of the building system that composes it. The purposes of this assessment are (1) Knowing the condition of the building; (2) Reconstructing the maintenance planning strategy to reduce the amount of damage in the following evaluation period (3) Re-assessing the impact of operational damage on the work environment. The research phase begins with (1) grouping buildings that have the same function; (2) Determining the range of data and categorization; (3) Conducting inspections and data collection; and (4) Data analysis. Before an appraisal of a building, the appraiser needs the initial cost of the building during the construction process. If the initial cost of the building is not well documented, the cost of building construction is obtained by calculating estimates. Through estimation calculations, appraisers can determine the factors that can affect the evaluation process of a building. Determination of the initial cost is calculated based on a sample that has been grouped by function and purpose. The results obtained will be able to assist in making decisions for scheduling maintenance and inspections, functional and re-design of buildings, or OHS (Ocupational Health and Safety) evaluation reviews.

Authors: Florencia Leona Denada
Published: March 2024

Latent Tuberculosis Infection (LTBI) is as a condition when Mycobacterium tuberculosis (MTB) persists in the body without causing symptoms while maintaining viability with the possibility to become active tuberculosis in the future. The detection of LTBI is an important strategy from WHO to end the chain of tuberculosis. LTBI can be diagnosed by using the IGRA test. IGRA uses specific antigens of MTB, early antigenic target-6 (ESAT-6), to induce interferon-gamma production by antigen-specific T cells. In the IGRA test, the cut-off value is explicitly needed to distinguish healthy people from LTBI patients. This study aimed to find IGRA's adjusted cut-off value in Indonesia. The subjects were 150 people, which were 50 healthy people, 50 subjects with active TB, and 50 with suspected LTBI. Isolated Lymphocytes derived from PBMC sand were cultured in a complete RPMI medium and induced by Esat-6 for six days. IFN-g levels were assayed from supernatants by the sandwich Elisa technique. Statistical analysis was used to determine cut-off values for IFN-g derived from healthy and diseased patients. The highest aptitude index (κ value) that could discriminate between healthy and LTBI groups was 0.925 at a concentration of 0.792 ng/ml of IFN-g, hence the cut-off value to diagnose LTBI was 0.792 ng/ml of IFN-g. Based on this value, out of 40 suspected cases of LTBI, up to 17 (42.5%) and 23 without LTBI (57.5%) were found. So, the conclusion was that the adjusted cut-off value for IFN-g to diagnose LTBI in Indonesia was 0.792 ng/ml.

Natural adsorbents such as chitosan can be effective adsorbents used to reduce heavy metal concentrations in the environment. One of the weaknesses of chitosan is the strength of the mechanical structure and low stability. Therefore, crosslinking modifications were carried out to improve the mechanical structure and reduce solubility. This study aims to determine the effect of sodium tripolyphosphate on the process of making chitosan shrimp shell-sodium tripolyphosphate adsorbent and to determine the optimum conditions of the variation of the adsorbent and the mass used. The research variables used were the sodium-tripolyphosphate concentration of 0.25%; 0.50%; and 1.00%, the mass of the adsorbent in the column was 5 grams and 7.5 grams, and the sampling times were 20 minutes, 40 minutes, 60 minutes, 80 minutes, 100 minutes, 120 minutes, 140 minutes and 160 minutes. The results showed that the 1% chitosan-sodium tripolyphosphate adsorbent with a mass of 7.5 grams was the most optimal in reducing the content of Fe by 92% and Mn by 93%.

There are several methods used to calculate the level of reliability of a distribution system, such as the Section Technique method and the Reliability Index Assessment (RIA) method, by considering reliability index values such as the System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI), and Customer Average Interruption Duration Index (CAIDI). This study analyzed the reliability of the 20kV distribution system in the Prajurit feeder at the Balaraja main substation. Based on the analysis using the Section Technique method, the reliability index values for the Prajurit feeder were obtained at 2.1876 for SAIFI, 20.9624 for SAIDI, and 9.5823 for CAIDI. The analysis using the RIA method showed reliability index values of 2.2025 for SAIFI, 21.3445 for SAIDI, and 9.6910 for CAIDI. The reliability of the distribution system was also tested using computer simulation, and the reliability index values were found to be 1.5697 for SAIFI, 18.6939 for SAIDI, and 11.9092 for CAIDI. Therefore, based on the analysis, simulation, and reliability index standards stated in SPLN 68-2: 1986, the electric power distribution network in the Prajurit feeder can be categorized as a reliable network.

Based on the data obtained, 1.3 billion tons of food waste are generated annually worldwide. This amount constitutes one-third of the food successfully produced for human consumption. And Indonesia has succeeded in becoming the second largest producer of food waste in the world. In this study, observations will be made of the effect of the mixture composition on food waste originating from Jambangan TPS on BSF larvae bioconversion. The research was conducted on a field scale with a running time of 12 days. Data analysis carried out included waste reduction index, efficiency conversion of digestive feed, biomass weight gain, compost yield testing and protein content in larvae. Compost results will be compared with SNI 19-7030-2004 concerning Compost Specifications from Domestic Organic Waste. And the results of the protein content in the larvae will be compared with SNI (8290.1: 2016) concerning laying hen feed (production period) and with conventional chicken feed. The results showed that the highest percentage of reduction ability was from the food waste and amino acid reactor which managed to reach 80%, and the final weight of the larvae touched 0.2-0.3 gr. The laboratory test results stated that the compost and protein content complied with the existing SNI. Meanwhile, the palatability test states that fresh maggot has the best value. But the drawback of fresh maggot is that it can cause damage to the digestive tract, besides that it also has low shelf life..

One source that contributes greatly to urban air quality is traffic. The proximity of schools to vehicles will put students at greater risk of exposure to high concentrations of particulate matter. SMP Negeri 1 Jambi City is an education center located in an urban area and adjacent to a busy road. CFD models are good at modeling the movement of pollutants in urban areas by taking into account the influence of buildings. The purpose of this study is to determine the concentration of PM10, PM2.5, PM1, and PM0.1 at SMPN 1 Jambi City based on direct measurement results and CFD modeling results and then see how accurate the modeled PM concentrations are when compared to the results of direct measurements. The results showed that the average concentrations of PM10, PM2.5, PM1, and PM0.1 from direct measurements were 20.66 µg/m3, 11.79 µg/m3, 8.74 µg/m3, and 1.96 µg/m3, respectively, while the modeling results showed lower average concentrations. The ratio of the difference between the measured and modeled PM concentrations is in the range of 11.67 - 233.45% and with the percentage of RMSPE obtained >30% (invalid), where the requirement for a modeling to be valid so that the results can be trusted in explaining the actual phenomenon is when the validity percentage is <30%.

Leachate, a byproduct of water entering landfills, contains high amounts of organics, acids, metals, and dissolved salts, posing environmental risks. Due to leachate can be hazardous and there are few remediation alternatives, researchers are exploring leachate reduction methods using decomposing organisms like Black Soldier Fly (BSF) larvae. This research investigates BSF larvae's ability to decompose leachate, determines the quality of the final residue and analyzes the growth of the larvae. BSF larvae were grown for 12 days on a mixture of substrate and leachate. The variations used are the solvent content of the leachate solution (75%, 50%, 25%, and 0% solvent) and the type of substrate (bran, tofu dregs, or a mixture of tofu bran-dregs). Using leachate in raising BSF larvae effectively degrades leachate and creates standardized organic fertilizer. The substrate type and solvent content of the leachate solution affect media reduction. As the solvent gets smaller or the leachate concentration increases, the medium shrinks more. The highest media shrinkage of 58.83% is achieved by combining bran and tofu dregs with 0% leachate solution solvent concentration.

Leachate is a liquid containing extracted, dissolved, and suspended materials from waste in a landfill. Leachate from Klotok landfill contains pollutant loads that do not meet the water quality standards, necessitating treatment. In this study, parameters considered were COD, TSS, and TN. Anoxic-Oxic Moving Bed Biofilm Reactor (MBBR) was chosen due to its compact footprint, low sludge production, ability to handle high COD loads, and not requiring periodic backwash. Variations including media type, media volume, and Hydraulic Retention Time (HRT) were applied to reduce pollutant parameter concentrations. The experiment was conducted in batch-continuous mode. The derived parameter concentrations yielded promising results using a biocube/sponge media in the reactor, constituting 50% of the leachate volume, with an HRT of 45 hours. Upon continuous operation under the best variations for parameter reduction, COD, TSS, and TN values were achieved as 160 mg⁄L, 132  mg⁄L, and 31.5  mg⁄L, respectively. Meanwhile, the average removal percentages for COD, TSS, and TN were 87%, 50%, and 87% respectively. Additionally, microorganism identification was performed in the anoxic-oxic moving bed biofilm reactor, revealing the presence of microorganisms such as coliforms, Bacillus sp., and Pseudomonas sp.

Garbage is something that is produced from human activities and then it is not used and then thrown away. Coastal waste has become a global problem and is an issue that is being widely discussed. This is because coastal waste has an impact on the environment, economy and human health. In addition, the behavior of the community in disposing of waste on the coast is also a habit that can have a negative impact. To be able to overcome the waste problem, three aspects are needed, namely the government, society, and waste management procedures. This study aims to determine the impact of waste disposal on the coast to the surrounding environment. The type of research used in this study is a descriptive research type with a qualitative approach that refers to data in the form of words that have clear and definite characteristics. The results of this study also show that the behavior of coastal communities influences environmental damage. This is also influenced by the low level of public education about the Mola coastal area. The government can work together with the community to save Mola Beach from environmental damage caused by people's behavior.
