Abstract

Along with the increase in the production of broilers, the amount of liquid waste produced will increase. Liquid waste resulting from chicken slaughterhouse activities will cause odor pollution and aquatic pollution. Chicken slaughterhouse wastewater (CSWW) is suitable for use as a raw material for Liquid Organic Fertilizer (LOF) production, based on nutrient analysis results of waste samples collected from a facility in South Jakarta. According to the results of the analysis, the Biochemical Oxygen Demand (BOD) was measured at 214.52 mg/L, and the Chemical Oxygen Demand (COD) was significantly higher at 2310 mg/L. Furthermore, the samples contained 37.39 mg/L of oil and fat, and an ammonia (NH3) concentration of 37.39 mg/L. The presence of high concentrations of organic substances, such as protein, oil, and fat, confirms the potential of CSWW as a valuable raw material to produce LOF. To facilitate this study, bioconversion, the fermentation method was employed. In this study, four formulations of (LOF) were prepared using varied concentrations of a carbon source (sucrose) and Effective Microorganisms 4 (EM4) solution bacterial inoculum. The efficacy of these formulations was subsequently evaluated via a bioassay on land kangkong (Ipomoea reptans Poir). The results revealed that the greatest positive effect on plant growth was achieved by the LOF variation, which incorporated 150 g of sucrose and 0.05 L of EM4 solution. Samples of plants that were given the addition of LOF showed the highest number of leaves, as many as 24 strands and the highest plant height value of 18 cm.

Abstract

This study aims to analyze the influence of reverse logistics on consumer satisfaction with cosmetic products at PT Nectars Natura Karya. Reverse logistics, which involves the management of product returns for recycling, repairs, or waste handling, is a crucial element in enhancing sustainability while meeting the expectations of modern consumers. The study employs a simple linear regression analysis method to understand the relationship between reverse logistics as the independent variable and consumer satisfaction as the dependent variable. Data were collected through questionnaires distributed to consumers of PT Nectars Natura Karya's best-selling product, Tamanu Daycream. Based on the simple linear regression test results, the simple linear regression equation obtained is Y = 0.666 + 0.464X, indicating that if the reverse logistics variable is zero or constant, consumer satisfaction increases by 0.666 units. The coefficient value for the reverse logistics variable is 0.464, meaning that a one-unit increase in reverse logistics will increase consumer satisfaction by 0.464 units or 46.4%. Furthermore, the R value (correlation coefficient) is 0.876, signifying a very strong relationship between reverse logistics and consumer satisfaction. The R2 value (coefficient of determination) is 0.767, indicating that 76.7% of the variation in consumer satisfaction can be explained by reverse logistics in the model, while the remaining 23.3% is explained by other factors outside the model. With an R2 of 0.767, the model is categorized as substantial, implying a very strong relationship between reverse logistics and consumer satisfaction. In the hypothesis testing, the t_calculated value of 17.778 far exceeds the t_table value of 1.664. Thus, H0 is rejected, and Ha is accepted, confirming that the relationship between reverse logistics and consumer satisfaction is highly significant.

Abstract

Heavy fuel oil utilization via combustion leads to negative impacts towards the environment. A cleaner way of heavy fuel oil utilization should be implemented, gasification is one. Gasification process can convert heavy fuel oil feed into valuable gas like hydrogen. Based on the simulation result, hydrogen purity (on dry basis) was obtained at 98,02% (volume). Study on temperature and addition of gasifying agent was also done. At high gasification temperature, more hydrogen tends to be produced. Steam addition also gives positive effect on hydrogen yield. Environmental impacts evaluation using life cycle assessment method has been performed. Based on the simulation, this process significantly contributes to climate change with the score of 2.630 kgCO2eq. Carbon dioxide utilization via enhanced oil recovery can overcome this problem. From economical point of view, annual net income after tax is at Rp 45.956.031.943,16 with the annual return on investment rate of 59,46%, which is economically justified.

Abstract

The production of crude palm oil was highly dependent on the operational efficiency of the digester unit, in which improper control of temperature, material level, and stirring speed often resulted in reduced productivity and unstable operating conditions. This study aimed to address these issues by developing an automated control system to improve digester performance through integrated sensing and motor control. An automation system based on a microcontroller was designed and simulated using multisensing technology, including temperature monitoring within an optimal range of 90–95 °C, material level detection with a minimum threshold of 75%, and direct current motor speed regulation through a motor driver module. System logic and operational behavior were evaluated using Proteus simulation software prior to hardware implementation. The simulation results showed that the proposed system was able to automatically stop the digester motor when the operating temperature exceeded 95 °C or when the material level dropped below the predefined threshold, thereby preventing unsafe operating conditions and potential equipment damage. The automated response ensured more stable digester operation and reduced the risk of process inefficiencies. The overall findings indicated that the proposed low-cost automation system effectively enhanced process control and operational reliability. Furthermore, the implementation of this system demonstrated a potential improvement in production efficiency of approximately 20–30%. These results confirmed that microcontroller-based automation with multisensing integration provided a practical and efficient solution for optimizing digester operations in crude palm oil processing plants.

Abstract

Singapore's declaration to participate as a pioneering country in the energy shift and become the first Southeast Asian country to implement a carbon pricing scheme on January 1, 2019, by imposing a carbon tax has led several major players in this business to divest their terminals or refineries in the Singapore area or shift their businesses to green energy, such as Shell and Advario. This phenomenon, however, does not eliminate dependence on fossil fuels. Therefore, demand for storage tank rental and bunkering services will remain and continue to increase, especially in the Strait of Malacca. This creates an opportunity for Pulau Sambu Fuel Terminal to become an alternative storage location, strengthened by its strategic location in the Singapore Strait and its currently unutilized condition. Regulatory challenges related to tax regulations directly impact the competitiveness of Pulau Sambu, which becomes less attractive when compared to existing terminals in Singapore and Malaysia. This research uses a mixed-methods approach, combining qualitative methods as well as analysis of secondary data. This research is structured using several analytical frameworks such as PESTLE analysis, Porter's Five Forces, VRIO, and the SWOT-TOWS matrix to obtain a comprehensive picture of internal and external conditions as part of an effort to obtain precise business and marketing strategies. Finally, this research gives a clear visual across both academic literature and industrial practices. For practitioners, the findings offer a blueprint for a phased business model, uniting investment strategies along with government engagement.

Abstract

Goods sorting (shiwake) activities at the Shimohana Logistics warehouse in Atsugi, Japan, constitute the focus of this study, which aims to identify potential hazards, assess risk levels, and evaluate the implementation of occupational health, safety, security, and environmental (HSSE) practices. A qualitative descriptive approach was employed through direct observations, interviews, and documentation review, with risk analysis conducted using the Job Safety Analysis (JSA) method and risk assessment based on likelihood and severity parameters aggregated using the geometric mean. The results identified 11 potential hazards encompassing mechanical, ergonomic, and environmental aspects, with risk levels ranging from low to extreme. The highest risk (RR = 16) was associated with forklift traffic interactions in the sorting area, while other high risks (RR = 9-12) were linked to non-ergonomic postures, repetitive manual handling, and prolonged exposure to cold temperatures. Moderate and low risks were found in manual trolley usage, unstable stacking conditions, and exposure to scanner lighting. The application of JSA integrated with HSSE principles enables a structured and systematic approach to hazard identification and risk control. The findings indicate that, despite efficient warehouse operations, significant risks remain in sorting activities, particularly in worker–equipment interactions and cold environment exposure. Therefore, targeted mitigation strategies including segregation of forklift and pedestrian pathways, ergonomic improvements, workload regulation, and the use of cold-resistant personal protective equipment are recommended. These measures are expected to enhance workplace safety, reduce accident risks, and support continuous improvement toward a safer and more sustainable warehouse operation aligned with the zero-accident principle.

Abstract

As an archipelagic nation, Indonesia holds tremendous potential for the development of renewable energy, one of which is ocean current energy, recognized for its stability, cleanliness, and sustainability. Pesisir Barat Regency in Lampung Province is a coastal region rich in marine resources, yet it still faces challenges related to dependence on fossil fuels and limited electricity infrastructure, particularly on Pulau Pisang. Despite being a world-class tourism destination, Pulau Pisang remains off-grid and relies solely on diesel generators. This study aims to address these issues by conducting hydrodynamic modeling using Delft3D software across 11 coastal districts and mapping the potential of Ocean Current Power Plants. The simulation results highlight the Pulau Pisang strait, the strait between Pulau Pisang and the mainland, as the most promising location. This area features mixed semidiurnal tidal characteristics, with average current velocities reaching 0.52 m/s and peak velocities up to 5.40 m/s. Based on the hydrodynamic profile and energy conversion efficiency, the Gorlov turbine is identified as the most suitable technology, with an estimated maximum energy output of 94,647.79 kW. The generated energy is intended to supply Pulau Pisang, supporting its transformation into an energy-independent and sustainable tourism zone, and paving the way for a clean energy-driven local economic transition.

Abstract

The demand for electrical energy in aquaculture, particularly in Pangkep Regency, continues to increase due to the need for nighttime illumination to ensure security and maintain fish activity. However, the geographical location of fish ponds, which are often situated far from the state electricity grid (PLN), creates a significant energy supply challenge. This study aims to design, construct, and analyze the performance of a standalone (off-grid) Photovoltaic (PV) system to supply electrical energy to a 4000 m² fish pond located in Bori Appakah Village. The research methodology includes site assessment, mathematical sizing of system components, system assembly, PVsyst 7.4.8 simulation, and empirical field testing conducted over three days. The total daily energy demand was calculated to be 1,560 Wh/day. The designed system integrates a 400 Wp monocrystalline PV module, a 12 V 300 Ah lead-acid battery bank, a 45 A MPPT solar charge controller, and a 1000 W pure sine wave inverter. Simulation results showed a Performance Ratio (PR) of 66.71% and a Solar Fraction of 93.56%, with an estimated annual energy yield of 554.44 kWh. Field measurements demonstrated that the system was capable of stably supplying power to 13 LED lighting points for 12 hours, with the PV module producing a peak output power of 150 W under fluctuating solar irradiance conditions. The study concludes that the proposed PLTS system is technically feasible and provides a reliable alternative energy solution for remote aquaculture operations.
