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.

Sweet orange peel (Citrus x aurantium L.) is an agricultural by-product rich in bioactive compounds including flavonoids, phenolics, terpenoids, and vitamin C with antioxidant and moisturizing potential. This study aimed to formulate and evaluate a body lotion using 15% ethanol extract of sweet orange peel obtained by maceration with 96% ethanol. Evaluations included organoleptic, homogeneity, pH, adhesion, spreadability, viscosity, irritation, cycling test, cream type, and DPPH antioxidant activity assessments. The preparation was semisolid, yellow, with a characteristic herbal aroma, homogeneous, pH 8, adhesion time of 4.10 seconds, spreadability of 9.9–11.1 cm, and acceptable viscosity. The preparation caused no skin irritation, remained stable through six cycling test cycles, and formed an oil-in-water (O/W) emulsion. Antioxidant activity showed an IC₅₀ of 284.6 ppm (weak category) compared to vitamin C as positive control (IC₅₀ 4.2 ppm). It was concluded that ethanol extract of sweet orange peel can be formulated into a stable and safe body lotion, though further optimization is needed to enhance its antioxidant activity.

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.

This study aims to analyze the impact of middlemen on the price of Fresh Fruit Bunches (FFB) of oil palm received by farmers in Lambur I Village, Tanjung Jabung Timur Regency, from a sharia economic perspective. This study also examines the FFB marketing patterns carried out by farmers and the factors that influence farmers in choosing where to sell their harvest. The method used is a qualitative approach with a case study research type. Data were obtained through in-depth interviews, field observations, and documentation to understand FFB marketing practices and the socio-economic relationships between farmers and middlemen. The results show that FFB marketing in Lambur I Village is carried out through three main channels: middlemen, the Marketing Chain of Trust (RAM), and palm oil processing factories. Most farmers choose to sell FFB to middlemen because the transaction process is easier, payments are fast, and transportation costs are not required. In addition, urgent financial needs, limited transportation facilities, and long-standing socio-economic relationships also influence farmers' dependence on middlemen. In practice, middlemen play a dominant role in determining prices, deducting approximately Rp 250–Rp 300 per kilogram from the factory price. From a sharia economic perspective, marketing practices through middlemen are essentially permissible as long as they are carried out with mutual consent and do not contain elements of usury, gharar, or injustice. However, the dominance of middlemen in determining prices indicates a bargaining imbalance that could potentially harm farmers, thus not fully reflecting the principle of justice in sharia economics

This study examines the role of the Lubuk Intan Village Unit Cooperative (KUD) in assisting in managing oil palm sales for smallholder farmers in Peninjau Village, Batanghari Regency. The background of this study is based on the suboptimal distribution of economic benefits to farmers, despite increasing sales through the cooperative. This situation indicates the need to strengthen the role of cooperatives in the harvest marketing system. This study used a qualitative approach with descriptive methods. Thirteen informants were interviewed: three administrators and ten members of the Lubuk Intan KUD in Peninjau Village, Batanghari Regency. The results indicate that the Lubuk Intan KUD plays a role in facilitating collective sales, providing price information, and creating certainty and transparency in the weighing and recording of harvests. This role has been able to improve marketing efficiency and member trust. However, its implementation still faces obstacles such as limited human resources, limited operational capital, and inadequate member participation.

The steering gear is a vital component in ship operations, functioning to control the ship’s direction accurately. The reliability of this system highly depends on the performance of the hydraulic system, where the mechanical seal plays a key role in maintaining system pressure and preventing oil leakage. This study aims to identify the main factors causing mechanical seal damage and analyze its impact on the performance efficiency of the steering gear AHTS Logindo Stamina. Qualitative data were obtained through participatory observation and in-depth interviews with the second engineer. Meanwhile, quantitative data were gathered by measuring technical parameters such as oil pressure, operating temperature, and rudder movement time, which were then compared with SOLAS standards. This damage results in oil leakage through the mechanical seal gap, abnormal noise in the hydraulic system, and a significant decrease in working pressure of -25,86%. The operational impacts include the occurrence of steering gear failure alarms, decreased hydraulic efficiency of 25.87%, and the risk of system failure that could endanger ship maneuverability. This study recommends preventive maintenance through oil quality monitoring, environmental condition control in the steering gear room, and periodic mechanical seal replacement in accordance with operational standards to maintaining optimal steering system performance.

Pregnancy is a period marked by significant emotional challenges for expectant mothers, with stress and anxiety being common issues that may adversely affect maternal well-being and fetal development. The limited availability of safe treatment options for pregnant women, particularly concerning pharmacological interventions, has prompted the exploration of more natural and non-invasive therapeutic alternatives. One increasingly popular method is aromatherapy, which utilizes essential oils to stimulate the limbic system in the brain, thereby promoting relaxation and reducing anxiety. This study aims to explore the effects of aromatherapy in lowering stress and anxiety among pregnant women through a literature review. The method employed involves collecting and analyzing findings from previous studies regarding the use of aromatherapy in pregnancy. Based on the available evidence, aromatherapy—particularly with lavender essential oil—has been proven effective in lowering levels of stress and anxiety in pregnant women. Several studies report a reduction in anxiety levels of up to 40% following the inhalation of lavender oil. However, factors such as the type of essential oil used, the method of application, and individual sensitivity may influence therapeutic outcomes. Despite its potential benefits, the safety of aromatherapy use remains a concern, particularly regarding essential oils that may be unsafe for use during pregnancy.

Introduction: The incidence of ARI in children is estimated at 0.29 cases per child/year in developing countries and 0.05 cases per child/year in developed countries. There are 156 million cases of ISPA and most of them occur in India (43 million), China (21 million) and Pakistan (10 million) as well as Bangladesh, Indonesia and Nigeria with 6 million cases each. Of all ISPA cases that occur in the community, 7-13% are serious cases and require serious cases and require hospital treatment. Method: This research is a pre-experimental research with one group pre-post test design.Results: The results of the study showed that there was an effect of giving water vapor therapy and eucalyptus oil on reducing the frequency of ineffective airway clearance in children at RSIA Sitti Khadijah, Gorontalo City because it was found that the average frequency of coughing was 10.33 times per day before and after giving honey. Of 2.5 cc every day for 3 days, it was found that the average cough frequency decreased to 5.73 times per day so it can be seen that the difference between the cough frequency before and after was 4.6 times per day. Therefore, giving water vapor therapy and eucalyptus oil to children who are experiencing airway clearance is not effective in reducing the frequency of coughing.Conclusion: The conclusion of this study is that there is an effect of giving water vapor therapy and eucalyptus oil on ineffective airway clearance in children at RSIA Sitti Khadijah, Gorontalo City with a significant value of 0.000.

Injectable contraception remains one of the most widely used family planning methods among couples of reproductive age. However, the success of this method is strongly influenced by the level of knowledge and attitudes of acceptors, which in practice are often still inadequate. This study aimed to evaluate the effectiveness of injectable contraceptive educational videos in improving the knowledge and attitudes of injectable contraceptive acceptors at TPMB Siti Juhariyah. The study employed a quantitative approach with a quasi-experimental one-group pretest–posttest design. A total of 30 injectable contraceptive acceptors were selected as samples using purposive sampling techniques. The intervention consisted of providing an educational video on injectable contraception, followed by the assessment of participants’ knowledge and attitudes before and after the intervention using structured questionnaires. Data were analyzed using statistical tests to determine differences between pretest and posttest scores. The results showed a significant increase in acceptors’ knowledge, which shifted from moderate and low categories to a good category after the educational video intervention. In addition, the acceptors’ attitudes toward the use of injectable contraception also demonstrated a significant positive change. Based on these findings, it can be concluded that injectable contraceptive educational videos are effective in improving the knowledge and attitudes of acceptors. Therefore, educational videos can be utilized as a supportive counseling medium in family planning services to enhance the quality of contraceptive care in independent midwifery practices.

This study aims to analyze the impact of the geopolitical conflict between the United States, Israel, and Iran in 2026 on global macroeconomic stability and climate change dynamics. Using a qualitative approach through a Systematic Literature Review (SLR), this research synthesizes findings from various international journal articles, reports, and academic sources. The results indicate that the conflict has significantly disrupted global energy markets, leading to a sharp increase in oil and gas prices. This energy shock has triggered global inflationary pressures, reduced purchasing power, and increased economic uncertainty across both developed and developing countries. Furthermore, monetary tightening policies implemented to control inflation have created trade-offs with economic growth, increasing the risk of global recession. On the fiscal side, government interventions such as energy subsidies have helped mitigate short-term impacts but have raised concerns about long-term fiscal sustainability. In addition, the energy crisis has slowed the transition toward renewable energy, thereby exacerbating climate change risks. The study highlights the interconnectedness between geopolitical conflict, macroeconomic instability, and environmental sustainability. Therefore, coordinated global policies and integrated economic strategies are essential to address these multidimensional challenges effectively.

This study aims to (1) describe the marketing channels of fresh fruit bunches (FFB) of oil palm under partnership and independent (self-managed) schemes in Merlung District, Tanjung Jabung Barat Regency; (2) analyze marketing margins, farmer’s share, and marketing efficiency for each scheme; and (3) compare differences in marketing margins and farmer’s share between single-level marketing channels in both business schemes. The research was conducted in 2025 using a survey method with simple random sampling techniques. The data used consisted of primary data obtained through direct interviews with farmers and marketing institutions, as well as secondary data from relevant agencies. Data analysis was carried out using descriptive analysis, marketing margin analysis, farmer’s share, marketing efficiency analysis, and Multivariate Analysis of Variance (MANOVA). The results show that there are two types of marketing channel patterns, namely single-level and two-level channels. The single-level marketing channel has lower marketing margins, higher farmer’s share, and better marketing efficiency. In addition, there are significant differences between single-level marketing channels in both business schemes. These findings imply that shorter marketing channels are more efficient and provide a greater share of the selling price to smallholder oil palm farmers

This study aims to determine the effect of palm oil fiber (PFFE) (Borassus flabellifer Linn.) levels in egg yolk citrate diluent (C-EY) on the quality of frozen semen from landrace crossbred boar. The material used was fresh semen from 3 landrace crossbred pigs aged 2-3 years. The experimental method was a Completely Randomized Design consisting of five treatments and five replications.

The cosmetic industry continues to grow rapidly along with the increasing demand for natural-based body care products, one of which is massage oil. Essential oils such as lavender, citronella, and chamomile are known to have synergistic effects as relaxation agents, anxiety reducers, and anti-inflammatory agents. To support the safety and effectiveness of their use, the selection of appropriate carrier oils, such as olive oil, almond oil, and virgin coconut oil (VCO), is required due to their good penetration ability and moisturizing properties. This study aimed to determine the effect of variations in carrier oils on the physical and sensory characteristics of aromatherapy massage oil preparations and to identify the most optimal formulation. The research was conducted experimentally by formulating three massage oil formulations using a combination of lavender, citronella, and chamomile essential oils with different carrier oil compositions. The evaluations included organoleptic tests, pH, viscosity, specific gravity, stability, irritation tests, and hedonic tests. The results showed that all formulations were liquid, homogeneous, stable for 28 days, had pH values within the normal skin pH range, met the required viscosity and specific gravity standards, and did not cause skin irritation. Based on the hedonic test, formulation F2 was the most preferred by respondents and was determined to be the best formulation due to its most favorable aroma, texture, and comfort during use. Therefore, variations in carrier oils influence the characteristics of massage oil preparations and enable the determination of the optimal formulation

This study aimed to form late and evaluate a natural massage oil preparation using a combination of lavender, citronella, and chamomile essential oils with olive oil as the carrier oil. The background of this research was based on the increasing public demand for natural body care products that are safe, non-irritating to the skin, and provide relaxation effects. The three essential oils used possess therapeutic activities, including relaxation, antimicrobial, anti-inflammatory effects, as well as the ability to relieve stress and muscle tension. The study employed three formulation variations (F1, F2, and F3) with different compositions of essential oils. The evaluation of the preparations included organoleptic tests, pH measurement, viscosity, specific gravity, physical stability testing, hedonic testing, and irritation testing. The organoleptic test results showed that all formulations had a liquid form, a deep light-yellow color, and a characteristic aroma corresponding to the dominant essential oil in each formulation. The pH values of all formulations were stable at 5, indicating safety for skin application. Viscosity values were within the ideal range for massage oil, between 4.124–4.735 cPs, and specific gravity values were within the standard range. Stability testing over 28 days revealed no significant changes in color, aroma, pH, or viscosity. The irritation test indicated that none of the formulations caused skin irritation in panelists. Hedonic testing showed that formulation 2 was the most preferred in terms of aroma, while formulation 3 was preferred for texture. Overall, all three formulations were considered stable, safe, and well accepted by consumers, indicating their potential use as natural massage oil products.

Independent plantations are a favorite in the Jambi Regional economy, as they are a source of economic growth, employment, exports, and foreign exchange for the region. Despite their relatively low productivity, oil palm plantations in Jambi Province have a major competitive advantage compared to other commodities. This study aims to describe, analyze competitiveness, analyze policy impacts, and conduct sensitivity tests on independent oil palm plantations. The research location was in Merlung District, selecting three sample villages: Tanjung Paku Village, Merlung Village, and Lubuk Terap Village purposively, with a total sample of 43 farmers. The data analysis method used the (PAM) method. The results of the analysis show that independent farmers still have relatively low productivity. The DRCR value is 0.379 (<1) and the PCR value is 0.368 (<1) which indicates savings in the use of domestic resources by 37.9% and 36.8%. These results indicate a comparative and competitive advantage. The divergence impact shows a negative impact, meaning that government policies are not distorted properly, as indicated by an NPCI value of 1.18 (> 1) and an NPCO value of 0.87 (< 1). Sensitivity tests show that independent oil palm plantations still have competitiveness (< 1), despite experiencing policy distortions such as input price increases (11% and 25%) and a decrease in FFB prices (45%).
