This study was conducted based on the crucial role of diesel generator engines as the primary source of electrical power on board ships, making their operational reliability essential. One of the factors influencing generator engine performance is lubricating oil temperature. Excessive lubricating oil temperature may reduce lubrication effectiveness, increase friction between moving components, and lower engine efficiency. Therefore, this research aimed to identify the causes of high lubricating oil temperature in diesel generator engines and determine appropriate corrective actions. The study employed a descriptive quantitative approach. Data were collected through direct observation, interviews, and documentation during sea practice aboard MV. CL FLANDERS from 4 July 2024 to 5 July 2025. The data were analyzed using simple linear regression to examine the relationship between generator load and lubricating oil temperature. The findings revealed that generator load had a significant effect on the increase in lubricating oil temperature. Under normal operating conditions, the lubricating oil temperature ranged from 60°C to 72°C, while under abnormal conditions it increased to between 68°C and 81°C. The abnormal rise in temperature was mainly caused by cooling system problems, particularly a dirty LO cooler, scale deposits on the sea water pump impeller, and blockage in the cooling capillary pipes. The regression equation under normal conditions was Y = 45 + 0.30X, whereas under abnormal conditions it was Y = 53.5 + 0.30X. Elevated lubricating oil temperature resulted in lower oil viscosity, higher fuel consumption, and reduced diesel generator engine performance. Therefore, regular maintenance of the LO cooler, sea water pump, and continuous temperature monitoring are necessary to maintain optimum engine performance.

Travertine is a non-marine carbonate rock precipitated from calcium- and bicarbonate-rich waters, commonly associated with hot springs, streams, and lakes in tectonically active regions. This study presents a systematic literature review of travertine deposit characteristics, encompassing mineralogical composition, geochemical signatures, petrographic textures, morphological types, isotopic properties, biotic–abiotic controls on formation, early diagenesis, and petrophysical implications. The synthesis indicates that travertine is predominantly composed of calcite, with aragonite forming under conditions of elevated temperature, high Mg/Ca ratios, and rapid CO₂ degassing. Travertines display exceptional textural diversity, ranging from abiotic crystalline crusts to microbially mediated fabrics such as shrub, peloidal, and stromatolitic structures. Major morphologies include fissure ridges, mounds, terraces, cascades, and slopes, strongly governed by tectonic setting, topography, hydrology, and substrate geology. Stable isotopes (δ¹³C and δ¹⁸O), strontium isotopes, trace elements, and REE patterns effectively constrain fluid provenance and distinguish thermogene from meteogene travertines. Microbial activity plays a crucial role in biomineralization, influencing precipitation rates, crystal morphology, and lamination patterns. Early diagenetic processes occurring during active deposition may significantly modify primary fabrics and geochemical signals. Travertine petrophysical properties exhibit distinctive porosity–velocity relationships, making them valuable analogues for subsurface carbonate reservoirs. This review highlights that travertines record complex interactions among physical, chemical, biological, and geological processes and hold significant value for paleoenvironmental reconstruction and carbonate reservoir studies.

Facies analysis and thin-section petrography are complementary and essential approaches for determining the lithological characteristics of deep-water deposits. Deep-water sediments are formed by diverse depositional processes such as turbidity currents, debris flows, slumps, and pelagic suspension settling, producing a wide range of lithofacies with distinctive textural, compositional, and sedimentary structural attributes. This literature review synthesizes studies that apply facies analysis and thin-section petrography to characterize deep-water deposits across various basins and geological ages worldwide. Field-based facies analysis emphasizes lithology, sedimentary structures, bed geometry, and vertical–lateral facies relationships to reconstruct depositional environments. In contrast, thin-section petrography provides microscopic insights into mineral composition, grain texture, cement types, porosity, and diagenetic features that are not observable in the field. The integration of these methods, often combined with advanced techniques such as XRD, SEM, and geochemical analyses, has proven effective in distinguishing lithofacies, understanding sedimentary processes, and evaluating reservoir quality. The review highlights that grain size, sorting, cement type, pore-throat size, and diagenetic processes are key controls on lithological characteristics and reservoir potential in deep-water systems. Therefore, the combined application of facies analysis and thin-section petrography provides a comprehensive framework for interpreting deep-water sedimentary systems.

Cholelithiasis is the formation of hardened bile deposits within the gallbladder due to an imbalance in the chemical composition of bile, which can cause symptoms ranging from abdominal pain to serious complications such as cholecystitis, biliary obstruction, and gallbladder infection. This study aimed to determine the relationship between patient characteristics and the length of hospital stay in cholelithiasis patients at Cut Meutia General Hospital. This study used an analytical observational design with a cross-sectional approach and a retrospective study, employing a total sampling technique with 50 patients. The results showed that most patients were female (52.0%), with the largest age group being late elderly (28.0%). The most common surgical technique was laparoscopic cholecystectomy (42.0%), and the majority of patients received surgical management (60.0%). Bivariate analysis using the Chi-Square test showed significant relationships between age (p=0.000), gender (p=0.044), surgical technique (p=0.029), and management (p=0.045) with the length of hospital stay in cholelithiasis patients. The conclusion of this study is that there is a relationship between patient characteristics and the length of hospital stay in cholelithiasis patients.

The global energy crisis and climate change are driving the development of biodiesel as a renewable energy source. Graphite as an additive shows significant potential in improving the efficiency and reducing emissions of biodiesel. This study maps graphite-biodiesel research in Southeast Asia using a meta analysis of systematic reviews of 68 publications from Scopus, Web of Science, and ScienceDirect from 2015-2024. The results show that Malaysia leads in publication contributions (32%), followed by Thailand (28%) and Indonesia (18%). The optimal graphite concentration of 50 ppm increases brake thermal efficiency by 8.3% and reduces CO (15.7%), HC (12.4%), and smoke (18.9%) emissions, although there is an increase in NOx (6.8%). Palm oil methyl ester dominated the research (56%). Indonesia has strategic opportunities with abundant feedstock and graphite deposits, but faces challenges in research infrastructure, limited international collaboration, and the absence of an integrated national roadmap. Infrastructure investment, human resource strengthening, and industry academia collaboration are needed to accelerate national biodiesel research.

The Special Region of Yogyakarta (DIY) is characterized by high seismic activity due to its proximity to the subduction zone and the presence of active fault systems, particularly the Opak Fault. The 2006 Yogyakarta earthquake revealed significant vulnerability in local building structures and highlighted the complex geological conditions governing seismic wave propagation. This study aims to calculate and map the Peak Ground Acceleration (PGA) distribution in Prambanan District, Klaten Regency—one of the areas closest to the 2006 earthquake source. PGA values were estimated using the McGuire attenuation relationship, based on a moment magnitude of Mw 6.3 and the hypocentral distance to 88 observation points distributed at approximately 900-meter intervals. The resulting PGA map indicates values ranging from 26.7 to 31.7 gal, with a clear spatial trend showing increasing intensity from the northern to the southern parts of the study area. Higher PGA values occur in regions near the Opak Fault and in areas dominated by unconsolidated volcanic deposits of the young Merapi formation. These loose sediments amplify seismic waves, resulting in stronger ground motion compared to areas composed of more compact sedimentary rocks. The spatial pattern of PGA corresponds well with the distribution of structural damage recorded during the 2006 earthquake. The findings emphasize the significant role of local geology and fault proximity in shaping seismic hazard levels. Consequently, this study provides essential insights for disaster mitigation strategies, land-use planning, and structural vulnerability assessment within the Prambanan area.

The 2006 Yogyakarta earthquake, with a magnitude of 6.3 Mw, caused severe structural damage and significant casualties, highlighting the high seismic vulnerability in the Special Region of Yogyakarta (DIY). Tectonic activity in this region is strongly influenced by the subduction of the Indo-Australian Plate beneath the Eurasian Plate and the presence of active faults, particularly the Opak Fault. Local geological conditions dominated by young volcanic deposits and unconsolidated alluvial sediments further enhance seismic wave amplification. This study aims to estimate the Peak Ground Acceleration (PGA) in Prambanan District using the empirical McGuire (1977) attenuation relationship based on parameters from the 2006 earthquake. Analysis was conducted on 113 observation points to map the spatial distribution of ground acceleration. The results indicate that PGA values range from 29.2 to 35.6 gal, with the highest values concentrated in the southern and southeastern parts of Prambanan, characterized by alluvial deposits of the Opak River. In contrast, lower PGA values occur in the northern area underlain by more consolidated young volcanic materials. These findings emphasize the significant influence of lithology and geomorphology on local site response to seismic shaking. The results provide an important basis for seismic hazard assessment and mitigation planning in Prambanan and surrounding areas.

This research seeks to define polycyclic aromatic compounds, which are chemical compounds consisting of fused aromatic rings that do not contain heteroatoms or substituents. Many of these compounds are known to be carcinogenic and are primarily produced through the incomplete combustion of carbon-containing fuels such as wood, coal, diesel, grease, and tobacco. Pure polycyclic aromatic compounds generally appear as colorless, white, or pale green solids that often develop a yellowish tint over time. These substances are commonly found in coal tar, crude oil, creosote, and tar deposits in industrial and urban environments. Despite their widespread occurrence and potential health risks, only a limited number of polycyclic aromatic compounds are utilized in industrial applications, including the manufacture of medicines, dyes, plastics, and pesticides. Furthermore, this research examines the distribution, persistence, and accumulation of these compounds in the environment, as well as their toxicological effects on human health, ecosystems, and long-term environmental sustainability.

This material provides an in-depth overview of the fundamental distinctions between Islamic banks and conventional banks, covering their underlying principles, contract types, operational mechanisms, legal frameworks, and organizational structures. Islamic banks operate based on Islamic values derived from the Qur’an, Hadith, and the rulings of the National Sharia Council (DSN-MUI), emphasizing strict prohibitions on riba, gharar, and maysir. Contracts such as wadiah, mudharabah, musyarakah, murabahah, ijarah, salam, and istishna’ are applied to promote fairness and profit-sharing. In contrast, conventional banks rely on positive law and interest-based systems as their primary source of income. Legally, Islamic banks are supervised by the Sharia Supervisory Board (DPS) to ensure compliance with sharia principles, while conventional banks adhere solely to general financial regulations set by authorities like the Financial Services Authority (OJK) and Bank Indonesia. The operations of Islamic banks include fund mobilization, financing, and financial services without the use of interest, whereas conventional banks earn revenue from the interest spread between deposits and loans. Although both bank types share a similar organizational structure, Islamic banks incorporate an additional layer of sharia oversight. Overall, Islamic banks aim to balance profitability with ethical and spiritual values (falah), while conventional banks primarily focus on maximizing financial returns. This material highlights Islamic banking as an ethical alternative within modern financial practices, promoting justice, sustainability, and broader economic well-being.

This study examines how the profit-sharing system is implemented in the Easy Mudharabah Savings product at Bank Syariah Indonesia (BSI) Cimahi Branch Office in accordance with Statement of Financial Accounting Standards (PSAK) 405 about Mudharabah Accounting. This study combined field observation and literature review in a descriptive qualitative manner. Interviews, documents, and literature reviews on the National Sharia Council's (DSN-MUI) fatwa on the mudharabah contract were used to gather the data. The findings demonstrate that the Easy Mudharabah Savings program at the BSI Cimahi Branch has been appropriately and sharia-compliantly executed in conformity with PSAK 405 regulations. Customer deposits, as opposed to the bank's permanent liabilities, are recorded as Temporary Syirkah Funds. Based on the agreed-upon nisbah and the average daily balances of the clients, the profit-sharing method is used to calculate the profit-sharing. Furthermore, PSAK 405 is followed in the presentation and disclosure of financial statements, while there is still opportunity to further customer information transparency. All things considered, the results of this study show that the Islamic banking profit-sharing system's implementation of PSAK 405 upholds the values of equity, cooperation, and openness.

Left ventricular hypertrophy (LVH) can be identified through both electrocardiography (ECG) and echocardiography, with echocardiography recognized as the gold standard for the assessment of LVH. This imaging modality determines the presence of LVH by evaluating the left ventricular mass index (LVMI). For diagnostic purposes, LVH is defined in males as a left ventricular mass index greater than 115 g/m² and in females as greater than 95 g/m². Despite the high accuracy of echocardiography in diagnosing LVH, access to this examination is not universal across all healthcare facilities. Consequently, electrocardiography, a widely available, non-invasive, and cost-effective diagnostic tool, serves as an alternative for the diagnosis of LVH. Several criteria exist for the electrocardiographic assessment of LVH, including the Sokolow-Lyon and Cornell voltage criteria. However, the sensitivity of these electrocardiographic methods remains relatively low, with reported sensitivities of 17% for the Sokolow-Lyon criteria and 35% for the Cornell criteria. In left ventricular hypertrophy, the interstitium experiences changes characterized by fibrosis and other deposits. These alterations can reduce the expression of hypertrophic myocardial tension and limit the diagnostic capabilities of surface electrocardiograms. Additionally, several factors influence electrical tension, including variations in chest wall thickness, heart muscle activity, the distance of the electrode from the left ventricle, and lung activity. The presence of these limiting factors can increase the rate of false negatives in diagnosis. In 2017, Peguero and Lo Presti introduced novel criteria for the diagnosis of LVH, defined by evaluating the deepest S wave and summing it with the S wave in lead V4. According to these new criteria, LVH is identified as ≥ 2.8 mV in men and ≥ 2.3 mV in women. The Peguero-Lo Presti criteria demonstrate improved sensitivity when compared to traditional criteria such as Sokolow-Lyon and Cornell, offering enhanced diagnostic accuracy.

This study aims to describe the management of the Keceme Drinking Water Supply System SPAM as an effort to overcome drought in Waru Hamlet, Girisekar Village, Panggang District, Gunungkidul Regency, Special Region of Yogyakarta. The drought problem in the area has been going on for a long time, thus demanding a sustainable solution to meet the community's clean water needs. This study uses a qualitative approach with data collection techniques through observation, in-depth interviews with SPAM managers and the community, and documentation. Data analysis was carried out with reference to George R. Terry's management theory which includes four management functions, namely planning, organizing, actuating, and controlling. The results show that the existence of the Keceme SPAM greatly helps the community in obtaining access to clean water, although various obstacles still exist. The main obstacles include planning that is mostly not documented in writing, limited number and capacity of human resources in management, technical problems in the form of lime deposits that disrupt water flow, and high operational and maintenance costs of the network. However, the existence of social capital in the form of a spirit of mutual cooperation among the community, as well as policy support and facilities from the village government, are important factors driving the sustainability of SPAM management. This research is expected to provide practical contributions as a reference for other regions facing similar challenges, particularly in optimizing the use of local water sources as a sustainable drought mitigation strategy.

The Waste Bank is an initiative born out of public concern for the environment, particularly in addressing the growing waste problem. The problem faced by the Seruni Waste Bank Association is that the management of waste deposit data is still carried out using conventional bookkeeping, which often results in errors in recording the nominal amount of waste deposits. This error results in losses for the Waste Bank Association and a lack of transparency between officers and members and customers. The purpose of this study is to help create a waste bank management system so as to reduce losses for the association. The research methodology employed is the waterfall methodology, which involves a research design comprising needs analysis, system design, implementation or coding, program testing and evaluation, and maintenance. The definition of users obtained from the results of observations and interviews resulted in two levels of users: owner and junior. System testing includes blackbox testing with test cases that are all accepted or valid, and user acceptant testing with results that are strongly agreed to be accepted by the association. This system has proven effective in helping officers manage waste bank data, especially in reporting waste deposit transactions, thereby improving the performance and transparency of Seruni waste bank operations.

The background of this research is the importance of pursuing knowledge based on good morals. The formation of Islamic character based on good morals is an important aspect that needs to be emphasized in students' lives, both in the school environment and in society. This is because good character is a reflection of the success of education, especially education based on Islamic values. However, at SMP Ma'arif NU 2 Kemranjen, several student behavioral problems were still found that indicate the suboptimal formation of Islamic character. Some students appeared unprepared when submitting memorization targets (deposits), were still outside the classroom when learning began, and arrived late to participate in the 0-hour habituation program. These problems indicate the importance of evaluating the effectiveness of the 0-hour habituation program that has been implemented by the school as an effort to form Islamic character. Therefore, this study aims to determine whether there is an effect of the 0-hour habituation program on the formation of students' Islamic character. This study used a quantitative approach with a descriptive survey method. The population in this study were all 107 eighth-grade students of SMP Ma'arif NU 2 Kemranjen from three classes. Data collection techniques were conducted through documentation of the 0-hour habituation program scores given by teachers and the Islamic character formation questionnaire completed by students. The data analysis technique used was descriptive statistics, with the calculation of averages, percentages, and data categorization. The results of the study indicate that the 0-hour habituation program did not have a significant impact on the formation of students' Islamic character. Nevertheless, this program is still being implemented because it is believed to have various benefits that can support the long-term character education process. This research contributes to schools in evaluating and developing more effective strategies for forming students' Islamic character.

The results of the evaluation of the rationality of drug use for hyperuricemia and gout arthritis showed that patients who were given several versions of drugs with the xanthine oxidase inhibitor group 64% were allopurinol with patients with the most appropriate indications, the right patient, and the right dose of 96%.

Financing in Indonesia, especially banks, is very important, especially for business actors, this is a natural thing considering that banks have a strategic role in national development in order to realize a just and prosperous Indonesian society. Regulations regarding Sharia financing are regulated in Law No. 10 of 1945 and Article 1 number 2 of Law No. 10 of 1998 concerning amendments to Law No. 7 of 1992 concerning Sharia Banking (hereinafter referred to as the banking law) defines a bank as a business entity that collects funds from the community in the form of deposits and distributes them back to the community in the form of credit and/or in the form of claims in order to improve the standard of living of the people, but there is an inconsistency in the regulation in terms of guarantees. This legal provision continues until the implementation of the Sharia Banking Law, because there are no legal regulations governing sharia guarantees, therefore in terms of sharia banking practices, the guarantee procedures used by conventional banking are still applied, namely fiduciary guarantees and mortgage rights.

Afghanistan, often called a "geological treasure trove," is richly endowed with vast mineral deposits worth over $3 trillion. The minerals, including copper, lithium, iron, gold, and rare earths, can be used to resurrect the nation's economy, reduce dependence on foreign aid, and bring about political stability. However, three decades of conflict, political turmoil, corruption, and inadequate infrastructure have been a hindrance to the effective exploitation of the resources. This paper examines the role of mining in Afghanistan's economic and political development, distilling the opportunities and challenges in the industry. Drawing on comparative case studies from resource-rich countries like Botswana and Chile, the study highlights the importance of open government, robust regulatory institutions, and strategic foreign partnerships. The evidence suggests that an efficiently operated mining sector would be a driver of sustainable development, provided that Afghanistan addresses deep-seated systemic evils in the form of corruption, insecurity, and environmental degradation. The research concludes with policy imperatives aimed at maximizing the contribution of the sector to national development.

The aim of this activity is to be able to understand gouty arthritis and the practice of making non-pharmacological drugs from pineapple juice and honey to reduce uric acid levels in the body. This health education can increase the knowledge of Purwodadi village residents to do their best to treat gout arthritis using traditional medicine. Health education for residents can increase knowledge and skills in using simple traditional medicines

The aim of this research is to analyze the influence of the exchange rate and BI rate on deposits. The population in this study is all exchange rate data, BI rate and deposits from commercial banks in Indonesia. Sampling was taken by taking monthly data from the exchange rate, BI rate and deposits available from January 2014 to December 2023. The results of hypothesis testing show that hypothesis 1 (H1) that the exchange rate has a negative effect on deposits is proven and can be interpreted as meaning that an increase in the exchange rate will reduce amount of deposits at commercial banks in Indonesia. Hypothesis 2 (H2) that the BI rate has a positive effect on deposits is proven and can be interpreted to mean that an increase in the BI rate will increase the number of deposits at commercial banks in Indonesia.
