Oil spills during exploration and transportation can pollute the land and water environment. Oil Spill Dispersants (OSD) are needed to disperse petroleum spills, thus facilitating the subsequent handling process. Bio-OSD is an environmentally friendly product because it uses surfactants derived from palm oil. This study aims to obtain information about the marketing strategy for Bio-OSD products by considering market potential and marketing risks as one of the important stages in the commercialization process. The research was carried out by analyzing the needs and availability, form of the market, and conditions of competitors for the Bio-OSD product and designing a risk-based marketing strategy through a mix between Segmenting, Targeting, Positioning (STP), and Product, Price, Place, Promotion (4P), as well as risk analysis. They were using the House of Risk (HOR) method. As a comparison, commercial OSD products were used. The results showed that the Bio-OSD product gave positive and superior values in terms of quality and price parameters compared to commercial OSD products, so it was feasible to be commercialized. The B2B marketing strategy design results in segmentation and target markets aimed at PT Pertamina (Persero) subsidiaries, as well as product positioning as a diversified product. The marketing mix design resulted in products that meet the needs standards, with a price range of IDR 50,000-IDR 80,000/L, target sales in Java, and promotions carried out both online and offline. The marketing risk management plan indicates three priority risk mitigation actions namely; regular monitoring and analyzing of marketing data, training and development for improving workers capability, and expanding promotional media. Keywords: OSD, surfactant, palm oil, risk, marketing

Amid the development of blockchain technology in various sectors, this research proposes a novel Integrated Assessment Model to evaluate readiness for implementing blockchain-based systems. This research was carried out in stages using a modified project evaluation system approach, which includes a series of processes such as systematic literature review, observation and interviews, and case study assessment using BDD and SEM-PLS. A comprehensive literature review reveals several important areas for assessing blockchain technology adoption readiness: technical maturity, domain suitability, regulatory landscape, and stakeholder dynamics. Based on these findings, the proposed model is organized into five layers: technology, business, data, regulations, and user interface. As a follow-up research on the development of analysis and design of a blockchain-based traceability system in Kintamani coffee, BDD confirmed stakeholder engagement. In addition, user readiness to change using a blockchain-based system is determined primarily by technology compatibility (TC) based on SEM-PLS and IPMA results. The main contribution of this research is to blockchain adoption by proposing a comprehensive and practical framework - the Integrated Assessment Model. It is recommended that future research be directed at developing models for more specific case contexts, expanding suitability for emerging blockchain frameworks, focusing on specific regions, and longitudinal research in terms of adoption trends and barriers. Keywords: assessment model, implementation readiness, blockchain, traceability system, agri-food supply chains

The lack of proper planning and scheduling in the shipping process within the rice flour supply chain has resulted in various challenges, including missed products for consumers. This issue is particularly concerning due to the delicate nature of rice flour, which has a limited shelf life. Implementing a contract-based supply chain information system has proven to be beneficial in improving transparency and facilitating clearer information on product specifications to customers. The contract played an essential role because of the ability to adjust the description of a specific goal, enabling each supplier to customize the contract according to their needs. This customization includes specifying the duration of the product delivery process and the timeline for when consumers can expect to receive the product, thereby ensuring clarity and mutual understanding between all parties involved. Therefore, this research aimed to design business processes within the rice flour supply caused by using a contract, with a focus on minimizing distance and delays in routing and scheduling. Furthermore, it integrates the results of scheduling and routing with a contract in the form of invoices. The saving matrix method was used to calculate efficient shipping routes for distribution activities, resulting in a refined contract design tailored for rice flour transactions. The stakeholders included were the shipper manager, marketing department, and customers. By applying the saving matrix, this research effectively planned shipment scheduling and routing, optimizing the entire logistic process in the industry, and a prototype invoice design was developed for rice flour customers.

The integration of internet of things (IoT) with unmanned aerial vehicle (UAV) or drone, for precision agriculture (PA) in rural tea plantations is required to ensure optimal outcomes. However, rural settings presents exceptional challenges for data transmission, particularly in maintaining effective communication between drone and ground control stations (GCS). Therefore, this research aimed to develop a payload metadata identification model using long range (LoRa) technology, known for robust IoT capabilities of the model. LoRa was used to transmit drone data packets to GCS, including image data computations and onboard sensor information. Additionally, the research proposed IoT-drone trajectory planning model, specifically designed for PA in rural tea plantations. This model incorporated LoRa technology for data transmission, leveraging the effectiveness of the model in remote areas. Edge computing was also integrated into model to classify the suitability of tea plantation picking areas based on image captured with drone. An important component of the research was trajectory planning system, which optimized drone flight paths by considering location data, throughput data, battery energy consumption, and the computation of suitable picking locations. Finally, experimental results showed the effectiveness of the proposed model in identifying payload metadata, monitoring drone trajectory, and optimizing picking location paths in rural tea plantations.

A study was conducted to determine Jatropha fruits ripening uniformity on its tree and bunches characteristics. To get more information about its ripening off, the tree characteristics a respiration pattern was determined. The data were collected on ﬁ ve trees for each ten selected accessions (n=50) for fruit ripening uniformity on its trees study and ﬁ fteen bunches for each seven selected accessions (n=105) for fruits bunches ripening uniformity study at two jatropha pilot projects at Sabah state of Malaysia at the end of March 2009 when the trees were exactly one year old. This study conﬁ rmed that heterogeneous ripening occured in all jatropha accessions and within individual jatropha bunches. Respiration tests conﬁ rmed that jatropha is a climacteric fruit. The results showed an upsurge in CO2 production at the end of ripening and at the beginning of senescence. This study has revealed indications of the possibility to harvest jatropha fruit in bunches rather than harvesting individual ripe fruit, which could potentially improve harvest efﬁ ciency by reducing harvesting time and drudgery. Keywords: ripening, respiration rate, post-harvest, climacteric

Catalytic cracking is a conversion process by cutting the carbon chains of oil molecules into simple hydrocarbons. The process ofbreaking the hydrocarbon chain could be conducted by chemical means using a catalyst and hydrogen gas. The types of catalystscommonly used in the chemical industry are metals such as nickel (Ni), zinc (Zn), and cadmium (Cd). The metal can be used asa catalyst directly, but during the catalytic cracking process, the catalyst will thicken than it is imposible to re-use the catalyst.Therefore, the metal catalyst must be impregnated into a carrier material such as zeolite. The research is aiming for analyzing thecharacteristics of active natural zeolite catalyst with nickel-metal impregnation (ZAA/Ni), which consisted of surface area analysis,XRD, FTIR, and morphological analysis best catalyst. The zeolite used in this research is originated from Bayah Banten, whichhas been activated. The function of the catalyst can be improved by the presence of a carrier, namely nickel metal. The role of thecarrier is as a place for the active nucleus to spread, which can increase the effectiveness of the catalyst so that the catalyst can beused repeatedly. Results show the highest Si/Al ratio is 6.66, an intermediate catalyst with a Si/Al ratio = 2−10. The widestsurface area of the catalyst is at ZAA/Ni 3% of 974.44 m2/g; the crystallinity value the largest was 70.09%. Zeolite fromBayah Banten, impregnated with nickel-metal, can be used as a catalyst for upgrading bio-oil with a concentration of 3% ZAA/Niand 2% AA/Ni.

This study designs and evaluates a cultural narrative feature in a food recommender system to enhance emotional engagement and cultural relevance while preserving usability. The feature uses progressive disclosure and is implemented as a modular interface component that embeds local food stories within recommendation cards. Fifteen users participated in a task-based, triangulated UX evaluation (usability testing, heuristic evaluation, and thematic analysis). Although only 25% of participants interacted with the narrative element, those who did spent more than twice as long engaging with the content. Heuristic findings indicated issues in system-status visibility and visual transition, while thematic insights showed curiosity, emotional recall, and cultural identification. The results suggest that optional, contextual narratives can enrich recommender-system UX and can be integrated as maintainable modular components for iterative refinement

Oil-based soil pollution is a pressing global environmental issue and has serious impacts on ecosystems and human health. Hydrocarbon compounds, especially heavy fractions, are persistent and difficult to decompose naturally in a short time, thus requiring intervention to accelerate the environmental recovery process. This research focuses on developing strategies to increase the effectiveness of oil-contaminated soil degradation. The development of a palm oil-based oil spill dispersant (Bio-OSD) combined with bacterial endospores of Bacillus pseudomycoides RAY21 offers an innovative approach to bioremediation. This particular bacterial endospore was selected for its capacity to sustain the viability of a potent biological agent until the point of application. The bacterial growth process was monitored to determine the optimal harvesting time by measuring optical density (OD600) at hourly intervals using a spectrophotometer until the stationary phase was reached. Following the harvesting of bacterial cells, various stressors were applied to stimulate sporulation, which included high-temperature incubation (80°C), nutrient deprivation, and their synergistic combination. The efficacy of the sporulation process was validated through endospore staining with malachite green. The resultant endospore pellets were integrated into the Bio-OSD and subjected to viability assessments every three days over a 24-day period using the Total Plate Count (TPC) method. The biodegradative capacity of the Bio-OSD containing endospores was evaluated through the analysis of Total Petroleum Hydrocarbon (TPH) degradation in artificially contaminated soils (3%) across a 28-day incubation. Findings indicated that optimal bacterial cell production occurred in Nutrient Broth, with peak harvesting at 40 hours. Moreover, the most effective sporulation was attained under combined stress conditions specifically, exposure to high temperature (80 °C for 24 hours) concomitant with nutrient deprivation (NaCl 0,85%) as demonstrated by the presence of green-stained endospores. This study provides evidence that Bio-OSD functions effectively as a stable carrier medium for bacterial endospores over a period of up to 24 days. The Bio-OSD formulation incorporating Bacillus pseudomycoides RAY21 endospores demonstrated the capability to degrade 78% of Total Petroleum Hydrocarbons (TPH) in petroleum-contaminated soil after 28 days of incubation. This degradation efficiency was significantly superior to that of the control treatment, which achieved a mere 32% degradation under the same laboratory conditions. To enhance the understanding and application of this approach, further investigations are recommended to be conducted on a larger scale, along with optimization analyses, to facilitate the development of more sustainable environmental remediation.

The palm oil industry is a major agricultural sector in Indonesia. This sector produces a significant amount of biomass, including palm kernel meal (PKM), which has tremendous potential as a sustainable feedstock for second-generation bioethanol production. This review aims to explore the enzymatic conversion of PKM to bioethanol as an environmentally friendly and feasible alternative to fossil fuels. The scope of the study covers pretreatment, enzymatic saccharification, fermentation, and purification technologies, with an emphasis on strategies that optimise sugar release and ethanol yield. A literature review method was used, analysing publications from 2010 to 2025 sourced from Google Scholar and Web of Science, filtered based on their relevance to PKM utilisation and bioethanol production. The results show that PKM, which is rich in cellulose and hemicellulose, can be effectively hydrolysed using enzyme consortia that include endomannanase, β-mannosidase, and cellulase, achieving high sugar conversion rates. Pretreatment methods including autoclaving and hot water were found to increase enzyme accessibility, while fermentation through simultaneous saccharification and fermentation (SSF) showed higher ethanol yields compared to separate hydrolysis and fermentation (SHF). In addition, bioethanol purification through a combination of distillation and adsorption achieved a fuel purity of 99.5%. Overall, the enzymatic conversion of PKM into bioethanol not only provides renewable energy but also contributes to waste reduction.
