Stroke patients often experience mobility impairments, which increase the risk of developing pressure ulcers (decubitus). Pressure ulcers are a common complication for patients with limited mobility, especially in the ICU. One intervention that can be used to reduce the risk of pressure ulcers is back massage using olive oil. This study aims to analyze the effect of back massage using olive oil on reducing the risk of pressure ulcers in stroke patients in the ICU at Sultan Agung Hospital. This study used a pre-experimental design with a one-group pretest-posttest approach, involving 17 respondents who received back massage using olive oil. The results showed that most respondents were aged 56-65 years (35.3%), the majority were male (70.6%), with comorbidities such as diabetes mellitus (52.9%), and the length of hospitalization was 3-5 days. Before the intervention, most respondents were categorized as being at moderate risk based on the Braden scale; however, after the intervention, the majority were no longer at risk of pressure ulcers. The Wilcoxon test showed a p-value of 0.001, indicating that back massage using olive oil had a significant effect on reducing the risk of pressure ulcers. In conclusion, back massage using olive oil is effective in reducing the risk of pressure ulcers in stroke patients in the ICU. Therefore, this technique can be used as an alternative intervention to prevent the occurrence of pressure ulcers in stroke patients.

This study aims to analyze the effect of transformer oil purification on oil breakdown voltage and evaluate its benefits in maintaining transformer performance and reliability. Oil purification is a crucial preventive maintenance step to preserve insulation quality and prevent operational failures caused by reduced dielectric properties. The study was conducted through several stages, including data collection, oil purification, measurement of breakdown voltage before and after purification, and evaluation of results. Data collection involved measuring the oil’s electrical properties according to SPLN 49-1:1982 and observing results using a Break Down Voltage (BDV) test. Purification of a Trafindo 400 kVA transformer was performed through visual inspection, connecting the inlet and outlet hoses to the purification machine, and circulating the oil until the breakdown voltage met the required standards. Results indicated that the oil breakdown voltage before purification was below standard due to reduced insulation quality caused by water contamination, charcoal particles, thermal degradation, and dissolved gases that weakened dielectric properties. Additional factors such as electrical stress, mechanical stress, and excessive loading also contributed to insulation deterioration. After purification, the oil breakdown voltage increased significantly to meet the standard of >30 kV/2.5 mm, demonstrating that purification effectively restores the oil’s insulating capacity and supports optimal transformer performance. Analysis confirms that the transformer oil remains suitable for use, and routine annual purification is recommended to maintain reliability, efficiency, and operational performance. This study highlights oil purification as an effective preventive measure for transformer stability, extending operational life, and reducing the risk of insulation failure. The findings provide valuable guidance for transformer maintenance in the electricity industry, ensuring safe and optimal long-term operation.

This study examines two main issues related to palm oil trading transactions in Kuala Keritang Village, Indragiri Hilir Regency, Riau Province. The first issue concerns the analysis of pricing mechanisms in palm oil trading, while the second focuses on the review of Islamic business ethics in such transactions. The objective of this research is to understand in detail how the price determination system operates in the local palm oil market and to assess the extent to which these trading practices align with the principles of Islamic business ethics. To address these issues, a qualitative descriptive method was employed. This approach was chosen because it allows for a comprehensive description of facts, data, and trading mechanisms while providing space for critical analysis in relation to Islamic values. Data were obtained through observation, interviews, and documentation, which were then described, analyzed, and discussed in order to answer the research questions thoroughly. The findings indicate that, in general, palm oil trading practices in Kuala Keritang Village are similar to other common trading systems, but they differ in terms of price-setting mechanisms. In practice, the price of palm oil is largely determined by buyers based on market conditions, which often creates injustice for farmers as sellers. From the perspective of Islamic business ethics, this practice does not fully comply with the principles of fairness, honesty, and mutual benefit, which are essential foundations of Islamic economic transactions. The study concludes that violations of Islamic business ethics principles, particularly regarding fairness in pricing, still occur in palm oil trading within the village. Therefore, improvements are needed in the transaction system so that palm oil trading in Kuala Keritang can be carried out in accordance with sharia principles, ensuring justice and mutual benefit for both sellers and buyers.

This study presents a modal analysis of Pertamina EP Cepu’s closed drain pump 510-P9002, which operates in the condensate–water treatment unit of the Jambaran Tiung Biru field. Field vibration measurements conducted in August 2024 indicated a fundamental frequency of 25 Hz, corresponding to 1×RPM of the driving motor, with maximum amplitudes reaching 13.46 mm/s. Such excessive vibration poses risks of mechanical damage, reduced equipment service life, and potential operational failure. To address this issue, finite element analysis (FEA) was employed to examine the dynamic response of the pump, determine its natural frequencies, and identify possible resonance conditions. A CAD model of the pump–vessel assembly was developed, meshed, and analyzed under actual boundary conditions. The results showed several natural frequencies ranging between 23.16 and 26.65 Hz, which are close to the excitation frequency, suggesting a very high likelihood of resonance. Various structural modifications were then evaluated, including a half casing and two types of full casings. Among these, the full casing B design provided additional stiffness in the motor support area; however, none of the modifications effectively reduced vibration within the internal components. Based on these findings, the study recommends the implementation of a dynamic vibration absorber (DVA) tuned to the excitation frequency, along with the redesign of structural components to shift natural frequencies away from operating excitation. These solutions are expected to improve operational stability, extend equipment lifespan, and enhance overall system reliability. The outcomes of this research provide important insights for managing vibration issues in pump systems operating under similar conditions, particularly in the oil and gas industry where continuous, stable operation is critical.

An oil spill at sea is the release of oil, either directly or indirectly, into the marine environment originating from shipping activities, oil and gas business activities, or other activities. In order to handle and prevent pollution due to oil spills, the IMO (International Maritime Organization) has made regulations that must be implemented in the world of international shipping. MARPOL Regulation 73/78 Annex 1 is a regulation issued to overcome this. In implementing this regulation, ships are required to have equipment in the form of an Oil Discharger Monitor (ODM). This tool functions as a monitor of activities in the process of disposing of waste into the sea by ships. So in this study the researcher wants to discuss the role of ODM (oil discharger monitor) in preventing marine pollution in accordance with MARPOL 73/28 Annex I standards.

Reservoir heterogeneity has long been recognized as a critical factor influencing the efficiency of enhanced oil recovery (EOR) methods. Among the techniques applied, cyclic waterflooding is considered one of the promising approaches due to its relatively simple operational design and potential to improve sweep efficiency. This method involves alternating water injection in specific cycles to mobilize trapped oil and redistribute reservoir pressure. However, the variation in geological properties such as porosity, permeability, and fluid saturation creates challenges in achieving uniform displacement, especially in reservoirs with high heterogeneity. Understanding the role of heterogeneity is therefore crucial for optimizing cyclic waterflooding applications. This study applies a literature review approach by synthesizing findings from previous experimental and field studies that evaluated cyclic waterflooding under different reservoir conditions. The analysis compares the performance of cyclic water injection periods across reservoirs characterized by varying levels of heterogeneity. Parameters such as injection rate, water breakthrough time, and oil recovery factor were considered in evaluating the effectiveness of this method. The results highlight that reservoirs with high heterogeneity often experience uneven fluid distribution, leading to early water breakthrough and reduced oil recovery. In contrast, reservoirs with relatively low heterogeneity tend to respond better to cyclic waterflooding, resulting in improved sweep efficiency and higher incremental recovery. Moreover, the optimization of cycle timing and water injection intervals appears to significantly mitigate the negative effects of heterogeneity. In conclusion, the study emphasizes that reservoir heterogeneity plays a decisive role in determining the success of cyclic waterflooding. Tailoring injection strategies based on geological variability is essential to maximize recovery efficiency. Future research should focus on integrating advanced reservoir characterization techniques with adaptive cyclic flooding models to further enhance oil production outcomes.

This study analyzes the effectiveness of implementing predictive maintenance (PdM) on the final drive components of the Komatsu PC200-8 unit at PT. Antareja Mahada Makmur, Site PT. Multi Harapan Utama, East Kalimantan, in an effort to reduce downtime and operational losses. Before the implementation of PdM in 2022, there were 12 repair cases for the final drive with a total downtime of 772.1 hours, repair costs amounting to IDR 310.6 million, rental income loss of IDR 208.03 million, and total losses of IDR 518.63 million. In 2023, during the PdM transition phase, the number of cases decreased to 4, with a total loss of IDR 252.05 million, although downtime remained high (714.6 hours) due to the limited scope of PdM implementation on certain units and components. In 2024, with full PdM implementation, the number of repair cases decreased to 5, with total downtime of only 96 hours and losses of IDR 45.75 million. The cost of PdM implementation for the year was only IDR 21.9 million. As of July 2025, no further damage to the final drive has been recorded, demonstrating a significant improvement in equipment reliability. The reduction in total losses from 2022 to 2024 amounted to IDR 472.88 million, indicating PdM’s effectiveness in avoiding significant costs through condition monitoring methods such as oil analysis, magnetic plug rating, thermal inspection, and oil leak testing (floating seal). The findings of this study confirm that PdM is effective in reducing downtime, repair costs, and enhancing asset management in the mining sector. It also improves equipment reliability and overall operational efficiency, proving PdM to be a successful strategy in reducing losses, increasing productivity, and supporting the sustainability of company operations.

The Terminal Loading Area (TLA) API at PT Pertamina Hulu Mahakam functions as a facility for processing oily water before being discharged into the environment. One of the main issues faced is the accumulation of thick floc (oil clumps) due to high emulsions in crude oil, along with the malfunctioning water spray valve on line 1, causing operators to resort to manual spraying using hydrant water. This increases the risk of exposure to hazardous chemicals such as Benzene, Toluene, and Xylene (BTX), which poses a health threat to workers. Therefore, improvements to the water spray system are needed to reduce BTX exposure and enhance the effectiveness of oil-water separation. This study aims to analyze the effectiveness of proposed improvements to the water spray system to reduce BTX exposure and improve the efficiency of oil-water separation. The methodology used includes literature review, field study, and technical testing. Proposed solutions include replacing or repairing the damaged water spray valve, adding piping networks to compartment 2 to distribute water more evenly, and using treated water (produced water) to optimize the system and reduce reliance on hydrant water. The results of the study indicate that replacing or repairing the water spray valve, adding piping networks, and using produced water effectively reduce BTX exposure while maintaining oil recovery effectiveness. The trials also showed that using the Oil Pump (P-3230 & P-3235) provides optimal pressure (8–9 barg) for water spray, compared to the less effective Water Pump (P-3200 & P-3205). Implementing these solutions is expected to reduce BTX exposure for workers, improve oil-water separation efficiency, and contribute to a safer and more efficient working environment.

Elevated blood cholesterol levels are known to be a major risk factor for cardiovascular disease. Hypercholesterolemia can trigger atherosclerosis, which in turn increases the risk of coronary heart disease and stroke. One approach to managing cholesterol levels is through the use of natural ingredients with antihyperlipidemic activity. White turmeric (Curcuma zedoaria Rosc) is an herbal plant long used in traditional medicine and contains bioactive compounds such as curcuminoids and essential oils. These compounds are reported to have antioxidant and anti-inflammatory activities, as well as potential as agents for lowering blood lipid levels. Herbal-based therapies are increasingly considered as safe alternatives to synthetic drugs in managing hyperlipidemia. This study aims to evaluate the effectiveness of a microencapsulated preparation of white turmeric ethanol extract in reducing total cholesterol levels in male rats (Rattus norvegicus) induced by a high-fat diet. The study was conducted experimentally using 25 rats divided into six treatment groups. The groups consisted of normal controls, negative controls, positive controls using simvastatin, and three treatment groups given white turmeric extract microcapsules at concentrations of 0.25%, 0.50%, and 0.75%. The microencapsulation technique was applied to improve the stability and bioavailability of the turmeric extract. Cholesterol levels were measured before and after treatment. The results showed that the treatment group with the 0.25% concentration produced the most significant cholesterol reduction, from 110 mg/dL to 59 mg/dL. These findings indicate that even at a relatively low concentration, microencapsulated turmeric extract can significantly reduce cholesterol levels in vivo. Therefore, it can be concluded that white turmeric extract in microcapsule form is effective in lowering total cholesterol levels, especially at the 0.25% dose. This suggests that Curcuma zedoaria microcapsules hold promise as a natural therapeutic option for managing hypercholesterolemia and reducing cardiovascular risk.  

The use of palm oil waste as boiler fuel is one of the innovative solutions in supporting the use of renewable energy while reducing the environmental impact of palm oil industry waste. Waste such as palm shells, mesocarp fibers, and empty oil palm bunches have high energy potential through direct combustion and other thermal technologies. This study aims to evaluate the potential use of palm oil waste as boiler fuel based on its calorific value, combustion efficiency, and environmental impact. The methods used include analysis of the physical and chemical characteristics of waste, boiler performance tests, and exhaust gas emission evaluation. The results show that palm oil waste has a high calorific value (15–20 MJ/kg), which makes it an efficient alternative fuel. In addition, the use of this waste is able to reduce dependence on fossil fuels while minimizing carbon emissions, thereby supporting the greenhouse gas emission reduction target. From an operational perspective, the use of palm oil waste in industrial boilers can increase combustion efficiency by up to 75–85%, depending on fuel conditions and boiler design. This makes palm oil waste not only economically valuable, but also strategic in supporting the transition to clean energy. Another advantage is that waste management becomes more targeted, because solid waste that is usually only an environmental burden can be reused as an energy source. However, some of the challenges that need to be considered include relatively high ash levels, the potential for corrosion in boiler equipment, and the need for emission control technology to comply with environmental standards. With the right mitigation strategy, palm oil waste can be processed into sustainable and environmentally friendly energy.

The relationship between Indonesia and Singapore has deep historical roots, tracing back to the ancient kingdoms. In the 7th century, the Strait of Singapore was part of the Srivijaya Empire. Later, in 1365, the Javanese hymn Nagarakretagama, written during the Majapahit era, mentioned a settlement on the island called Temasek, highlighting the long-standing connection between the two regions. Trade between Indonesia and Singapore has grown significantly over the years, reaching S$36 billion (US$29.32 billion), with Singapore being the largest foreign investor in Indonesia, having invested US$1.14 billion across 142 projects. Additionally, trade between the two nations surged to approximately $68 billion in 2010, with Indonesia's non-oil and gas exports to Singapore reaching their highest levels. The two countries have established robust cooperation in various sectors, including tourism, security, counter-terrorism, and environmental concerns. However, the relationship is not without its challenges. One significant issue is Singapore's role as a haven for Indonesian corruptors, with many fugitives from corruption cases seeking refuge there. This has led to tensions, particularly regarding the extradition of individuals convicted of corruption. To address these challenges, both nations must enhance the implementation of bilateral agreements, especially in political and security matters. There is a need to accelerate the technical finalization of military training areas as part of the defense cooperation agreement. Additionally, executing the extradition agreement and updating the memorandum of understanding between the Attorneys General of both countries would be crucial steps in addressing these issues and improving bilateral relations. In conclusion, while Indonesia-Singapore relations are multifaceted, with both cooperation and challenges, mutual commitment to resolving issues through diplomatic and legal means will be key to strengthening their ties in the future.

The purpose of this study is to analyze the influence of the work environment, work pressure, and social support on the performance of employees at the palm oil processing factory of PT. Tani Prima Makmur. This research was conducted at the office of the palm oil processing factory located in Lerehoma, Anggaberi District, Konawe Regency. A questionnaire was used as the primary tool for data collection, with a Likert scale employed to measure the responses to various statements related to the work environment, work pressure, social support, and employee performance. Multiple linear regression analysis was applied to examine the relationships between the independent variables (work environment, work pressure, and social support) and the dependent variable (employee performance). The results of the t-test revealed that the significance value of the work pressure variable (X2) is 0.000, which is smaller than the 5% threshold (0.000 < 0.05), indicating that work pressure significantly affects employee performance. Similarly, the significance value for the social support variable (X3) is 0.000, which is also smaller than 0.05, suggesting that social support has a significant impact on employee performance. In contrast, the significance value for the work environment variable (X1) is 0.615, which is greater than 0.05 (0.615 > 0.05), indicating that the work environment does not significantly affect employee performance in this case. These findings suggest that while work pressure and social support are crucial factors influencing employee performance, the work environment may not play as significant a role in improving performance at PT. Tani Prima Makmur. The study highlights the importance of providing adequate support and managing work pressure to enhance employee productivity in the palm oil processing industry. Further research may explore other potential factors that could contribute to improving employee performance in similar contexts.

Worm infestation due to Soil-Transmitted Helminths (STH) infection remains a public health problem, especially among elementary school children who frequently interact with contaminated soil. This condition is a major concern because it can cause long-term health problems, particularly in terms of physical growth and development of children. This study aims to identify the presence of STH worm eggs and larvae in soil and fecal samples of children in Bekoso Village, Pasir Belengkong District, Paser Regency, East Kalimantan. This study used a descriptive approach with a cross-sectional design. The samples used consisted of 23 soil points taken from oil palm plantations with sandy and loose soil criteria, as well as 16 fecal samples from elementary school children. Fecal examination was carried out using the Kato-Katz method to detect worm eggs, while the soil was examined using the Baermann technique to detect worm larvae. The results showed that 25% of children's fecal samples were infected with worm eggs, with 12.5% containing hookworm eggs, 12.5% Taenia sp. eggs, and 6.25% Ascaris lumbricoides eggs. In soil samples, 60.87% tested positive for Strongyloides stercoralis larvae and 26.09% tested positive for Ascaris lumbricoides eggs. These findings indicate a high risk of STH infection in children in the area. Environmental factors such as soil moisture, soil texture suitable for worm breeding, and poor personal hygiene practices are suspected to be the main causes of the spread of infection. This study emphasizes the importance of education on clean and healthy living behaviors (PHBS) and improving environmental sanitation to reduce cases of worm infection, especially in endemic areas such as Bekoso Village. More comprehensive prevention efforts are urgently needed to address this problem and improve public health, especially among elementary school children.

This study aims to investigate the sensory characteristics and nutritional content of macarons with the addition of kecombrang flower essential oil (Etlingera elatior). The research was conducted to determine the effects of various concentrations of kecombrang flower essential oil (3%, 5%, and 7%) on macaron quality. The sensory attributes evaluated included color, aroma, taste, texture, and overall preference, while nutritional analysis focused on key macronutrients such as carbohydrates, sugar, fat, protein, and ash content. The sensory evaluation utilized a single-factor ANOVA and Duncan's multiple range test to compare the effects of the different concentrations of essential oil. The results indicated that the addition of 5% kecombrang essential oil yielded the most favorable sensory scores, with the highest ratings in color (4.20) and texture (4.29). Furthermore, aroma and taste were rated highly, confirming that this concentration enhanced the overall quality of the macarons. Although the likeability score did not show significant statistical differences between treatments, all treatments were generally categorized as “liked” by the panel. For the nutritional content analysis, the macaron sample with 5% essential oil was selected for testing through a proxy method. The results indicated that the macaron had a carbohydrate content of 46.31%, sugar content of 31.62%, fat content of 3.05%, protein content of 19.08%, and ash content of 0.14%. These findings are noteworthy, as the macaron with kecombrang flower essential oil showed lower carbohydrate and fat content compared to a typical macaron, while it exhibited higher protein content. These results suggest that macarons with kecombrang essential oil may offer a healthier alternative to conventional macarons, particularly for those seeking lower sugar and fat content in their diet.

Pine soda is a natural fermented liquid from pine needles (Pinus merkusii) which has a distinctive aroma and contains bioactive compounds with potential as antimicrobial agents. This study aims to determine the antibacterial activity of pine soda against Staphylococcus aureus using the disc diffusion method and to compare its effectiveness with the antibiotic ampicillin as a positive control. The process of making pine soda is carried out through simple fermentation of Pinus merkusii pine needles under certain conditions to produce a fragrant liquid. Furthermore, qualitative tests are carried out to identify the content of bioactive compounds, such as flavonoids, phenols, and essential oils, which are known to have antibacterial properties. In the antibacterial activity test, paper discs that have been soaked in pine soda solutions with graded concentrations (2%, 4%, 6%, 8%, and 10%) are placed on agar media that have been inoculated with S. aureus. The results of the observation showed the presence of inhibition zones in each treatment with varying sizes. The largest inhibition zone was obtained at a concentration of 10% with a diameter of 10 mm, which is included in the medium inhibition category. As a comparison, ampicillin produced an inhibition zone of 26.3 mm, while distilled water, the negative control, showed no inhibition zone. These findings indicate that the antibacterial activity of pine soda is influenced by its bioactive compound content, although its effectiveness is still lower than that of standard antibiotics. This potential opens up opportunities for developing pine soda as a safe natural antibacterial agent, whether in the form of health products such as antiseptics, natural cleaners, or functional beverages that support body health. Further research is needed to optimize the fermentation process, increase the concentration of active compounds, and test its effectiveness against various types of pathogenic bacteria.

Background: Pregnancy is a physiological process experienced by every woman, but it can be accompanied by various discomforts, both physical and psychological. In the third trimester, hormonal, physical, and emotional changes often trigger complaints such as anxiety, difficulty sleeping, and discomfort. These conditions, if not managed, can negatively impact the health of the mother and fetus, including increasing the risk of pregnancy complications. One non-pharmacological approach that is increasingly in demand to address these problems is aromatherapy, namely the use of essential oils from plants as a complementary therapy. Objective: This literature study aims to explore the effectiveness of aromatherapy in reducing anxiety levels and improving sleep quality in pregnant women, especially in the final trimester. Methods: A narrative literature review was conducted by analyzing ten national journal articles published between 2014–2024. Articles were selected through a purposive sampling method based on the suitability of the topics with aromatherapy, pregnancy, anxiety, and sleep quality. Results: Most studies show that aromatherapy, especially with lavender, orange, and chamomile essential oils, has a positive effect in reducing anxiety levels and improving sleep quality. The mechanism of action of aromatherapy is thought to involve stimulation of the limbic system in the brain via the olfactory pathway, which plays a role in regulating emotions, inducing relaxation, and reducing sympathetic nervous system activity. These effects help reduce tension and facilitate better sleep in pregnant women. Conclusion: Aromatherapy has been shown to be a safe, easy-to-implement, and effective complementary intervention for addressing anxiety and sleep disturbances in pregnancy. Healthcare providers, particularly midwives, are advised to integrate this therapy into holistic antenatal care to support the overall well-being of pregnant women.

This research is motivated by the phenomenon of scarcity of 3-kilogram LPG (Liquefied Petroleum Gas) occurring in several sub-districts within Kudus Regency. This scarcity is frequently caused by misdirected distribution, wherein the subsidized gas, which pursuant to Article 3 Paragraph (1) of Presidential Regulation of the Republic of Indonesia Number 104 of 2007, is intended for low-income households and micro-enterprises, is instead accessed by middle-to-upper class individuals and sold at prices exceeding the government-mandated retail price (Harga Eceran Tertinggi/HET). The purpose of this study is to examine the implementation of the aforementioned Presidential Regulation in the distribution of 3-kg LPG within a specific sub-district of Kudus Regency, and to identify the inhibiting factors affecting its execution. This research employs a descriptive qualitative method using a field study approach. Data were collected through observation, in-depth interviews with LPG base outlet operators, sub-district government officials, and subsidy recipient residents, as well as through documentation of policies and distribution reports. The findings indicate that the implementation of the 3-kg LPG distribution policy in the field has not been conducted optimally. Many base outlets continue to sell subsidized LPG to retailers or to non-target consumers for the sake of higher profit margins, compounded by weak regulatory oversight. The impeding factors in policy implementation include: lack of understanding of the regulations by distribution actors, insufficient governmental outreach and socialization efforts, weak oversight and evaluation from Pertamina (the state-owned oil and gas company), and the absence of firm enforcement measures or sanctions against violations, which further exacerbate the problem.

The war between India and Pakistan has had a devastating impact on the economies of both the countries directly involved and those indirectly affected. The economic impacts of this armed conflict include significant infrastructure damage, reduced production capacity, soaring inflation, rising unemployment, and reduced investment flows. This geopolitical instability has also fueled uncertainty in global financial markets, triggering a "flight to safety" phenomenon, a shift in capital and investment to countries or instruments perceived as safer, such as US government bonds or gold. For Indonesia, this situation has the potential to significantly disrupt national economic stability. One impact is a reduction in foreign direct investment (FDI) inflows, as investors tend to hold back or relocate their investments to more geopolitically stable countries. Furthermore, pressure on the rupiah exchange rate could increase due to global financial market volatility and a decline in international investor confidence. The conflict could also hamper Indonesia's export traffic, particularly to countries with close trade ties with India and Pakistan. Furthermore, these tensions could disrupt global supply chains, particularly for energy and food commodities, many of which pass through strategic trade routes. If the conflict drags on, the price of crude oil and other raw materials could potentially rise sharply, which in turn would increase domestic production costs. This would have a direct impact on inflation and public purchasing power. This situation further complicates the management of Indonesia's monetary and fiscal policies, which currently face significant challenges, such as the imminent maturities of large government debt and a still-widening state budget deficit. The government must take strategic steps to maintain domestic economic stability, strengthen foreign exchange reserves, and encourage export market diversification to reduce over-reliance on conflict-prone countries.

The Cargo oil pump is one of the auxiliary units on board a ship, used to transfer cargo from one location to another during loading and unloading operations. On the MT Pangrango vessel, an issue occurred with the cargo oil pump: its performance declined, resulting in slow suction during the unloading process. This problem hindered efficient cargo operations, as the pump was not functioning properly.This study aims to identify the contributing factors, impacts, and countermeasures for the decreased performance of the cargo oil pump. The research methodology applied in this thesis involved a descriptive approach combined with Miles and Huberman’s analytical method, with data validity tested via triangulation. Data collection techniques used to identify the problem included observation, interviews, documentation, and literature review.The results revealed that the pump’s shaft was worn due to excessive friction, and the ball bearing s exhibited wear and disintegration caused by lack of lubrication (grease). The recommended corrective actions were to add material to the shaft , perform realignment to correct any shaft misalignment, and implement routine maintenance—specifically, monthly grease lubrication. These measures, when properly applied, can significantly reduce the risk of Cargo oil pump damage.

Virgin Coconut Oil (VCO) is a high-quality coconut oil that is extracted from fresh coconut meat without the use of high heat or chemicals, preserving its natural nutrients and beneficial properties. The demand for VCO has increased in recent years due to its various health benefits, such as boosting the immune system, improving digestion, and providing antimicrobial effects. The oil is rich in medium-chain fatty acids, particularly lauric acid, which is known for its positive effects on cholesterol levels and cardiovascular health. This study focuses on the production of VCO using a natural fermentation method, a traditional technique that is gaining attention for its simplicity and environmental friendliness. In this method, mature coconut meat is grated and squeezed to extract the coconut milk, which is then fermented at room temperature for 24–48 hours. The fermentation process allows the separation of the oil from the milk, forming a clear oil layer on top, which retains the characteristic aroma of coconut. The quality of the produced VCO was analyzed by determining its acid value and saponification number. The saponification value, which indicates the amount of alkali required to saponify the fat, was found to be 50.49. The acid value, which reflects the free fatty acid content, was measured at 5.61. These results suggest that the VCO produced through natural fermentation is of relatively good quality, with a favorable acid value indicating lower rancidity. Overall, the study demonstrates that natural fermentation is an efficient, eco-friendly, and cost-effective alternative for VCO production. This method not only preserves the natural properties of the coconut oil but also offers a sustainable approach to producing high-quality oil for various health and cosmetic applications.
