This study is motivated by the proliferation of regulations that facilitate the exploitative extraction of natural resources in Indonesia as a consequence of the penetration of neoliberal ideology, which deviates from the mandate of Article 33 of the 1945 Constitution of the Republic of Indonesia. The significance of this research lies in the strategic role of Muhammadiyah through the "Constitutional Jihad" movement in restoring state sovereignty over natural resources for the benefit of the public welfare. The study aims to analyze the philosophical foundations of Constitutional Jihad in reconstructing the vision of a Progressive Indonesia (Indonesia Berkemajuan) and to examine Muhammadiyah’s legal advocacy strategies in resisting the hegemony of liberal economic policies. The research focuses on how Muhammadiyah’s philosophical framework and litigation strategies are capable of correcting national energy policies, as reflected in Constitutional Court Decision Number 36/PUU-X/2012. This research employs a normative legal method using statutory, case, and theological-ideological approaches. The findings reveal that, philosophically, Constitutional Jihad represents the transformation of Al-Ma’un theology and the concept of Darul Ahdi wa Syahadah into a constitutional framework that integrates divine sovereignty with popular sovereignty. In terms of strategy, Muhammadiyah utilizes Public Interest Litigation supported by interdisciplinary expert collaboration and moral mobilization rooted in civil society. The analysis of Constitutional Court Decision No. 36/PUU-X/2012 demonstrates that Muhammadiyah’s advocacy successfully invalidated unconstitutional provisions of the Oil and Gas Law that had weakened state control, while simultaneously reaffirming the state's direct management function over natural resources. The study concludes that Constitutional Jihad constitutes an effective form of national ijtihad in reconstructing a progressive, sovereign, and socially just legal order in Indonesia.

Aromatherapy is the use of essential oils derived from natural materials to improve physical and psychological well-being. One of the most popular aromatherapy products is the aromatherapy candle, which provides relaxation while creating a comfortable atmosphere. This study aimed to develop aromatherapy candles based on agarwood (Aquilaria malaccensis) leaf extract, evaluate product quality, analyze public acceptance, and identify their potential as an entrepreneurial opportunity. This study employed an experimental method with a descriptive approach. The research stages included the extraction of agarwood leaves through a distillation process, the formulation of aromatherapy candles, product validation by three experts using sensory evaluation, and a public acceptance test involving 40 respondents using a Likert-scale questionnaire. The results showed that the third experiment produced the best extract characteristics, including a golden-yellow color, a stronger distinctive agarwood aroma, and an oily texture. The public acceptance test indicated that the average scores for color, texture, ease of use, and aroma were 3.16, 2.90, 3.42, and 3.02, respectively, which were categorized as good to very good. These findings demonstrate that agarwood leaf extract has the potential to be used as an alternative ingredient in the production of aromatherapy candles, in addition to receiving a high level of public acceptance, the product possesses economic value and can be developed as an innovative product and entrepreneurial opportunity in the beauty, spa, wellness, and creative industries.

This study examines the gap between Nestlé’s sustainability commitments and the reality of ecological damage caused by the use of unsustainable raw materials in its global supply chain. Using a descriptive qualitative approach based on literature reviews and case study analysis, this study evaluates various data sources, ranging from scientific journals and corporate reports to documentation from independent organizations such as Greenpeace and the Rainforest Action Network. Findings indicate that Nestlé’s procurement of key commodities such as palm oil, cocoa, soy, dairy products, and singleuse plastics significantly contributes to deforestation, systemic plastic pollution, water extraction in vulnerable regions, and greenhouse gas emissions exceeding 87.5 million tons of CO₂e per year. In Indonesia, these highrisk areas are evident in palm oil sourcing in Sumatra and Kalimantan and cocoa sourcing in Sulawesi. Theoretically, this study argues that Nestlé’s sustainability governance exhibits a pattern of strategic decoupling, where public reporting on progress in primary supply chains is deliberately used to mask ongoing environmental damage within their hidden supply networks. Thus, this article makes a critical contribution by integrating supply chain management theory, environmental accountability, and the governance of multinational corporations.

Stroke is a neurological disorder caused by impaired blood flow to the brain, resulting in brain tissue damage and various functional impairments. One of the common problems experienced by stroke patients is sleep disturbance, which may be influenced by neurological deficits, limited physical mobility, pain, and post-stroke anxiety. Persistent sleep disturbances can delay the recovery process and reduce patients’ quality of life. The long-term use of sleeping medications may lead to adverse effects; therefore, safe and easily applicable complementary therapies are needed. This study aimed to determine the effectiveness of peppermint oil aromatherapy in improving sleep quality among stroke patients in the working area of Barebbo Community Health Center, Bone Regency. The method used was the implementation of complementary therapy through the administration of peppermint oil aromatherapy to stroke patients experiencing sleep disturbances. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) before and after the intervention. The assessment results showed that before the intervention, patients experienced poor sleep quality, characterized by difficulty initiating sleep, frequent nighttime awakenings, insufficient sleep duration, and daytime fatigue. After receiving peppermint oil aromatherapy, patients demonstrated increased comfort, reduced anxiety, improved ability to initiate sleep, and better overall sleep quality compared to their condition before the intervention. Therefore, peppermint oil aromatherapy was found to be effective in improving sleep quality among stroke patients and can be used as a complementary non-pharmacological intervention in nursing care.

This article analyzes the recurring flash floods in North Konawe Regency which occurred in 2000, 2013, 2016, 2018, 2019, 2020, and 2021 as ecological disasters causally linked to three decades of natural resource exploitation through logging, oil palm plantations, and open-pit nickel mining. Using the dual framework of political ecology and environmental justice, this article argues that these disasters are not neutral natural events, but rather the product of a structured system of injustice: the indigenous Culambacu People and Tolaki People communities who were excluded from decision-making processes regarding extractive permits have borne the greatest burden of the destructive impacts of such exploitation. The most dramatic event was the 2019 flood that devastated Tapuwatu Village, causing losses amounting to Rp 674.8 billion and displacing 9,908 people. The findings demonstrate that the dominant government narrative framing the floods as “natural disasters caused by high rainfall” constitutes a strategic denial that obscures structural responsibility. Empirical data including rates of deforestation, exceeded river carrying capacity, and the chronology of concession expansion correlated with disaster escalation support the ecological disaster thesis. Persistent poverty amid abundant natural resource wealth confirms the condition of a “sacrifice zone,” characterized simultaneously by distributive, recognitional, and procedural injustices.

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.

This research analyzes the interconnection between energy geopolitics and global security through the case study of Venezuela, the country with the world's largest proven oil reserves. The background highlights that energy has become a strategic commodity driving geopolitical tensions in the international system. The objective is to answer three fundamental questions: why energy is critically needed, how the distribution of the world's oil reserves creates strategic inequality, and how the Venezuela case illustrates resource grabbing mechanisms. The method used is qualitative with a single case study approach, employing neorealism and dependency theory as analytical frameworks, with data sourced from official reports of international organizations (OPEC, IEA, IMF, EIA), news media, and academic literature. The findings reveal that the United States' escalating pressure on Venezuela from economic sanctions, maritime blockades, to military threats reflects a systematic pattern of resource imperialism disguised as counter-narcotics efforts. The impact on Venezuela includes GDP contraction of 4 percent, hyperinflation exceeding 530 percent, and 8 million people displaced. The implications underscore that the current global energy order remains dominated by zero-sum logic, requiring reform of international energy governance to be more just and sustainable.

This research critically investigates the circulation of disinformation concerning the instability of fuel prices on the digital platform X and its subsequent implications for the polarization of modern society. In an era where unverified economic news frequently dictates public reaction, fake news often acts as a potent catalyst for mass anxiety. By implementing a quantitative framework driven by lexicon-based computational sentiment analysis, this study effectively processed a dataset of 500 public opinion samples extracted via Google Colab spanning from April 2024 to April 2026. To ensure computational accuracy and eliminate textual noise, the data underwent a rigorous preprocessing phase encompassing case folding, alongside the systematic removal of URLs, account mentions, numbers, hashtags, and punctuation marks. The statistical outcomes revealed a highly disproportionate emotional landscape, overwhelmingly dominated by 451 negative reviews. In stark contrast, neutral observations and positive affirmations were nearly absent, recording only 40 and 9 instances, respectively. The data compellingly illustrates that the relentless influx of pessimistic narratives regarding economic instability directly induces financial panic, undermines rational discourse, and severely fragments cyberspace into deeply polarized factions.

This study is based on the increasingly rapid development of the knowledge-based economy, where human capital is now regarded as one of the important assets in creating a company’s competitive advantage, especially in the energy and oil and gas sectors in Indonesia. This study aims to determine the effect of human capital and labor intensity on corporate financial performance, which is proxied by Return on Assets (ROA) during the 2021–2024 period. The research method used is a quantitative approach with multiple linear regression analysis. The research data were obtained from sample companies selected using a purposive sampling technique. The results of the study show that human capital, proxied by Value Added Human Capital (VAHU), has a positive and significant effect on corporate financial performance. These findings indicate that good human resource management is capable of increasing the company’s profitability level. On the other hand, labor intensity is proven to have a negative and significant effect on financial performance. This indicates that a high level of company dependence on labor, without being balanced by operational efficiency, can reduce the company’s ability to generate profits. In addition, simultaneously both variables are able to explain 74.5% of the variation in Return on Assets (ROA), so it can be concluded that human capital and labor intensity have a considerable contribution to corporate financial performance. Based on these results, companies need to prioritize improving the quality and competence of the workforce rather than merely focusing on increasing the number of employees. This step is important to maintain the stability of corporate financial performance in the post-pandemic era. In addition, companies also need to effectively control labor costs so that a decline in net profit margins can be avoided.

This research aims to analyze: (1) the general characteristics of farmers who convert rubber land to oil palm plantations in Sungai Gelam District, and (2) the economic impact of this land conversion, particularly on farmers’ income. This study uses a quantitative approach with survey data collected from rubber and oil palm farmers. The results show that there are notable differences in farmer characteristics, including capital, labor use, and market access. The average income difference between rubber and oil palm farmers is IDR 2,712,000, indicating higher earnings from oil palm cultivation. Based on the BNT test, with a value of IDR 405,000, the average income difference exceeds the threshold, confirming that the difference is statistically significant. Furthermore, the calculated F value is greater than the F table value, which strengthens the conclusion that there is a significant difference in income between rubber and oil palm farmers. Therefore, land conversion contributes positively to farmers’ income improvement.

The plantation sector is one of the main pillars in Indonesia’s international trade.

This study aims to analyze the role of plantation commodity exports in Indonesia’s international economic performance and to identify the challenges faced. The method used is a descriptive qualitative approach through literature review from various scientific sources. The results indicate that plantation exports contribute substantially to economic growth, employment generation, and the stability of the trade balance. However, several challenges persist, including global price fluctuations, sustainability issues, and international trade barriers. Therefore, strategic policies are required to enhance the competitiveness of Indonesia’s plantation commodities in the global market.

The oil and gas industry requires efficient initial processing to separate reservoir fluids into oil, gas, and water phases. The Separator Unit is the main facility that plays a vital role in the surface facility production stage. This study aims to evaluate the type of separator used, identify control components, and understand the working principles and operational procedures of separators in the Main Production Facility (MPF) area. The methodology used is direct observation and literature studies during the implementation of practical work in July 2024 at PT. Citic Seram Energy Limited, Seram Non Bula Block, Maluku. The observation results show that the type of separator used is a Horizontal Three Phase Separator with tag codes 03-V-001A and 03-V-001B operating alternately. The separation process is carried out based on differences in fluid density utilizing gravity, supported by internal components such as deflector plates, mist extractors, weirs, and straightening vanes. Separator operation is maintained at an operating pressure of around 55 psig to ensure optimal separation efficiency and work safety. The conclusion of this study indicates that effective separator operation requires stable pressure and temperature control as well as routine maintenance to prevent sediment buildup and maintain product quality.

This research is motivated by the importance tank cleaning process on tankers to prevent cargo contamination, maintain cargo quality, and ensure crew safety. MT. Marina Prosperity, a chemical/oil tanker, uses the Butterworth system as the primary method for tank cleaning at every cargo change. However, in practice, technical and operational constraints are still found that affect the results of tank cleaning. The research method used is descriptive qualitative with data collection techniques through direct observation on the ship, interviews with the Chief Officer and Boatswain, and documentation studies in the form of log books and SOPs. Data were analyzed by focusing on three aspects, namely work efficiency, work safety, and operational procedures for using Butterworth. The results show that the use of Butterworth can increase time and energy efficiency compared to manual methods, with an average cleaning time of 2–4 hours per tank depending on the type of cargo. From a safety aspect, Butterworth reduces the need for crew to enter the tank, thereby reducing the risk of exposure to chemicals and hazardous atmospheres. However, work effectiveness and safety are greatly influenced by the condition of the equipment, the stability of water pressure, and the crew's discipline in implementing the SOP. On several occasions, steps such as nozzle cleaning, manual mopping, and safety meetings were not consistently performed, resulting in residual load in certain areas. With routine equipment maintenance, close supervision, and ongoing crew training, Butterworth can be optimized to produce more effective, safe, and standards-compliant tank cleaning process.

Generators are one of the important auxiliary aircraft needed on ships for power generation. During the operation of a diesel generator, continuous rotation occurs resulting in friction and erosion of the moving parts. The supporting factor for the smooth running of a diesel engine is a lubrication system that is supported by good lubricating oil quality, besides that it also needs to be supported by an adequate and good cooling system. The use of lubricants is one of the most important factors to ensure the performance of diesel engines. The lubricant is in charge of maintaining the condition of the engine so that it remains stable. This study aims to analyze the effect of using lubricating oil beyond the operating hours limit on engine heat. Furthermore, it also discusses steps to ensure diesel engine temperatures remain normal. This research was carried out during the practice of sailing on a ship for approximately one year. This study uses a descriptive quantitative research method. The primary data obtained directly utilizes observation methods, and documentation. Secondary data was obtained from existing articles and journals. The data analysis techniques used are descriptive analysis and inferential analysis. The results of this study show that the working hours of lubricating oil use have a significant influence on the increase in the temperature of diesel generator engines as evidenced by hypothesis tests on two engine units, namely AE1 and AE2. In the AE1 unit, a t-value of 18.467 with a significance of 0.000 was obtained, while in AE2 the t-value was 14.289 with a significance of 0.000. The significance value in both units is less than 0.05 so it can be concluded that the working hours of lubricated oil have a significant influence on the temperature of the genarato diesel engine on the ship.

Submarine pipelines are vital infrastructures in aviation fuel distribution, carrying high risks of operational disruption, safety issues, and environmental pollution. In 2025, the aviation fuel receiving submarine pipeline at Integrated Terminal Ampenan was deformed due to mechanical pulling by MT Anargya I, causing system shutdown. This incident created risks of seawater intrusion, marine pollution, and potential fuel shortages at Lombok International Airport. This study evaluates the effectiveness of applying a double-ended draining method combined with an oil bubble trap as a fast, safe, and sustainable solution for submarine pipeline repair. Using a case study and descriptive-analytical approach based on the Continuous Improvement Program (CIP), the research analyzed quality, cost, delivery, safety, environmental, and workforce aspects. The results showed the method effectively drained aviation fuel without seawater contamination, prevented marine spills, maintained fuel quality within specifications, and completed repairs before critical stock levels were reached. Additionally, it provided significant cost savings compared to emergency supply operations and achieved zero safety incidents and environmental pollution. The integration of double-ended draining and oil bubble trap proved to be an effective, adaptive innovation with strong potential for replication and standardization in other aviation fuel submarine pipeline systems.

This study aims to analyze the factors that influence the residential spatial system of the Marori and Mengge ethnic groups in Wasur Village, Merauke, South Papua, in the context of their involvement in the eucalyptus oil industry as a leading tourism product of Wasur National Park. A rationalistic qualitative approach is used with the main theory of behavioral setting to examine the relationship between behavior, local culture, and spatial structure. The results of the study indicate that houses not only function as domestic spaces, but also as places for the production of eucalyptus oil, especially at the packaging stage. The overlapping use of space causes space invasion, changes in function, and the emergence of high spatial flexibility. The space of the house undergoes a temporal functional transformation, adjusting to the intensity of economic activities and cultural rituals of the community. Private, semi-public, and spiritual spaces experience shifting boundaries, which have an impact on social relationship patterns and living comfort. This study also found that social structure, customary values (Boan/marga), and division of customary areas play an important role in the formation of the spatial system. These findings are expected to be an important contribution to the development of residential architecture based on behavior and local wisdom, as well as community-based conservation area management. This study also highlights the urgency of preserving the culture and existence of indigenous tribes amidst the current of modernization and the threat of extinction.

The purpose of this study was to determine how the application of Local Microorganisms (LOM) from stale rice and oil palm boiler ash impacts the growth and production of shallots (Allium ascalonicum L.) and to determine the interaction between the two treatments. Shallots are a horticultural commodity with high economic value, so efforts are needed to increase production through the use of environmentally friendly organic materials. The study used a factorial Randomized Block Design (RBD) with two factors and three replications. The first factor was LOM from stale rice with four levels (0, 20, 40, and 60 ml/L water/plot) and the second factor was oil palm boiler ash with four levels (0, 500, 1000, and 1500 grams/plot), resulting in 16 treatment combinations and 48 experimental plots. The parameters observed included plant height, number of leaves, number of tillers, fresh weight of bulbs, dry weight of bulbs, and bulb diameter. If there was a significant effect, the data were tested using analysis of variance (ANOVA). This research is expected to produce scientific data on the use of organic waste as an environmentally friendly fertilizer alternative.

Strawberries are horticultural commodities that are highly susceptible to postharvest deterioration due to their high respiration rate, microbial activity, and oxidative degradation, resulting in a relatively short shelf life. This study aimed to evaluate the effectiveness of edible coatings in extending strawberry shelf life through a systematic literature review (SLR) approach. Literature was collected from several scientific databases using keywords related to edible coating, shelf life, and strawberry, covering publications from 2019–2026. From an initial 109 articles, a selection process based on inclusion and exclusion criteria resulted in 35 articles specifically discussing the application of edible coatings on strawberries. The synthesis results showed that all studies reported an extension of shelf life after edible coating application, although the effectiveness was influenced by the type of material, formulation, and storage conditions. Chitosan was the most widely used coating material due to its natural antimicrobial activity and excellent film-forming ability. The incorporation of bioactive compounds such as essential oils, plant extracts, and phenolic compounds was proven to enhance antifungal and antioxidant activities. In addition, nanotechnology-based systems demonstrated better preservation performance compared to conventional systems. However, methodological standardization and industrial-scale validation are still required to support commercial implementation.

The practice of adulterating RON 92 (Pertamax) fuel has the potential to violate consumer rights and is contrary to applicable laws and regulations. The practice of mixing lower-quality fuel and then marketing it as RON 92 results in material and immaterial losses for users, including reduced vehicle performance and a loss of trust in business operators. This research aims to analyze the legal protections available to consumers regarding the practice of adulterating fuel based on Law Number 8 of 1999 concerning Consumer Protection and related provisions in Law Number 22 of 2001 concerning Oil and Gas. The research method used is normative legal research with a library research approach, through analysis of relevant laws and regulations, scientific literature, and secondary legal sources. The results indicate that the practice of adulterating fuel violates consumers' rights to comfort, security, safety, and accurate information as stipulated in Article 4 of the Consumer Protection Law, and violates the obligations of business actors as stipulated in Articles 7 and 8 of the Consumer Protection Law. Business actors can be held accountable for civil damages, dispute resolution through the Consumer Dispute Resolution Agency (BPSK), or subject to administrative and criminal sanctions in accordance with the Oil and Gas Law. Therefore, legal protection for consumers in cases of fuel adulteration requires an interconnectedness between effective government oversight, firm law enforcement, business actor accountability, and increased consumer legal awareness to ensure legal certainty and fairness in trade activities.
