Abstract

Petroleum industry activities produce waste such as petroleum hydrocarbons which damage to the soil environment due to changes in soil physical, chemical and biological properties. Oil Spill Dispersant (OSD) is a product that can break down waste of oil into small parts so that it can be dispersed naturally. Laboratory experiments aimed to find out optimize and performance test of OSD in the process of bioremediation with using bio-slurry technique on contaminated soil with heavy oil was carried out at Laboratory of Surfactant and Bio-energy Research Center (SBRC), Research and Community Service Institute of Bogor Agricultural University on January - August 2018 using contaminated soil with heavy oil. The experiment used Response Surface Method (RSM) with two factors, namely the incubation time factor (X1) and the Dispersant to oil ratio (DOR) (X2). The observed variables were soil Total Petroleum Hydrocarbons (TPH), pH, total microbes, and Chemical Oxygen Demand (COD) at soil solution. The results showed that the treatment of incubation time and its combination with DOR significantly reduced soil TPH, increased soil acidity, and increased soil total B. megaterium, but did not significantly affect on COD in soil solutions. Optimization of OSD with RSM showed that the higher DOR of OSD and the longer the incubation time, the higher also the rate of biodegradation of TPH. The optimum conditions were reached at DOR of 1.16:1 and incubation time of 7 days which were able to degrade soil TPH of 54.30%. The optimum conditions of soil pH (8.825) was reached at DOR of 1:1 and incubation time of 5 days, as well as the optimum conditions of B. megaterium (8.35 log CFU g-1) was reached at DOR of 0.86:1 and incubation time of 7 days. Oil spill dispersant (OSD) increased COD in soil solution in both uncontaminated and contaminated soils with heavy oil.

Abstract

Bilih fish is a freshwater fish endemic at Lake Singkarak, West Sumatra, and can be processed to increase this added value. The development of the fishery industry provides significant economic benefits and contributes to environmental impacts. This research aimed to assess the life cycle of crispy balado bilih fish products from Tujuh Muaro (TM) micro-enterprise and regular fried bilih fish products from Tabiang Biduak Lestari (TB) microenterprise using the Life Cycle Assessment (LCA) method. The scope of this study is cradle-to-grave, covering bilih fish fishing, transportation of raw materials and packaging, production processes, and distribution, with a functional unit of 100 g/package of bilih fish product. The impact analysis was conducted using SimaPro software, based on the CML 2001-IA baseline method for impact categories, including Global Warming Potential (GWP), Acidification (AP), and Eutrophication (EP). The micro-enterprises generated GWP impacts with normalised values of TM 6.51E-14 and TB 1.28E-14, AP 3.86E-14 and 1.19E-14, EP 5.81E-13, and 7.96E-14 person equivalents, respectively. Improvement scenarios at the production unit were carried out by substituting frying methods to reduce cooking oil usage, which lowered impacts with GWP reductions of 84.85% (TM) and 51.93% (TB), and AP reductions of 52.63% and 17.86%, EP reductions of 96.08% and 81.35%. In the transportation unit, selecting packaging suppliers closer to TM reduced impacts by 94.22% for GWP, 94.23% for AP, and 94.25% for EP. Utilising waste oil as biodiesel further reduced GWP impacts by 90.48% (TM) and 82.87% (TB), AP by 97.50%, and 94.78%, EP by 98.80%, and 98.14% respectively.

Abstract

The growing productivity of the Sanjai chips agro-industry contributes to increasing emissions along the production process. This study aims to evaluate the environmental impact of Sanjai chips production using the Life Cycle Assessment (LCA) method. The assessment follows LCA stages: goal and scope definition, life cycle inventory, and impact assessment. The system boundary is gate-to-gate, focusing on the production stages: peeling, washing, slicing, frying, seasoning preparation (balado), mixing, and packaging. The functional unit is 1 kg of Sanjai chips. For each kilogram of product, inputs include 2.01 kg of cassava, 0.35 liters of cooking oil, 9.63 liters of water, and 2.61 kg of firewood, with 9.63 liters of wastewater produced. Environmental impacts were analyzed using SimaPro 9.4.2 software and the CML-IA Baseline method. Results show that 1 kg of Sanjai chips contributes to Global Warming Potential (GWP) of 1.3619 kg CO₂ eq, Acidification Potential (AP) of 0.0131 kg SO₂ eq, Eutrophication Potential (EP) of 0.0740 kg PO₄ eq, and Ozone Layer Depletion Potential (ODP) of 8.09E-07 kg CFC-11 eq. The frying stage is the primary hotspot, contributing 78.7% of total impacts, mainly due to cooking oil use. It is recommended that future research expand the system boundary to a cradle-to-grave scope and include social and economic dimensions to achieve a more holistic sustainability assessment.

Abstract

Due to the harmful effects of air pollution on health, outdoor air pollution standards are getting stricter. Because of environmental changes, the Minister of Environment and Forestry Regulation No. 14/2020 must reevaluate the concentration limits for ISPU parameters. This study aimed to examine the concentration ranges and ISPU values for SO2, NO2, CO, O3, and PM10 in industrial estates on Java Island, and set concentration limits for five relevant ISPU parameters based on the results of monitoring, sampling, and toxicity studies. A drop in the average concentration of the five ISPU parameters in 2022 compared to monitoring from 2015 to 2019 shows that the air quality in industrial estates on Java Island is improving. The ISPU values between 10 and 56 are in the good-to-moderate range, which means that the air quality is still good enough for the health of humans, animals, and plants. The relevant concentration limit recommendations for ISPU in good-to-moderate categories for SO2, NO2, CO, O3, and PM10 were 42–77 μg/Nm3, 29–120 μg/Nm3, 3519–5037 μg/Nm3, 33–97 μg/Nm3, and 29–82 μg/Nm3, respectively. The results of this study can be used to improve Indonesia’s ambient air quality index system (ISPU).

Abstract

Banana chip processing in Lampung province uses two different frying methods, namely conventional frying and vacuum frying. The objective of this study was to compare the number of impact emissions generated from the banana chip production process in banana chip agro-industries in Lampung. This research was conducted based on the Life Cycle Assessment (LCA) method to assess the environmental impact emissions from the banana chip industry in Lampung, focusing on the impacts of Global Warming Potential (GWP), Acidification Potential (AP) and Eutrophication Potential (EP) with a function unit of 250 g/pack. Analysis using SimaPro 9.4.2 software. Analysis using the CML-IA Baseline method shows that the banana chip industry has a significant environmental impact with the largest impact by the industry, where the conventional frying method produces a GWP impact of 1.16 kg CO2 eq/package, EP 2.08E-2 kg PO4 eq/package and AP 3.6E-3 kg SO2 eq/package, while in the vacuum frying method, the GWP is 6.3E-1 kg CO2 eq/package, AP 2.3E-3 kg SO2 eq/package and EP 6,1E-3 kg PO4 eq/package. The calculated normalization data shows that the total impact of producing banana chips per package in conventional frying is 1.9E-12 person equivalent/package with the frying stage contributing 85.45% and in vacuum frying is 6.7E-13 person equivalent/package with the frying stage contributing 77.70%. The resulting emission impact value shows that the emission impact of conventional frying is higher than the emission impact of vacuum frying. However, an economic and social assessment of both frying methods needs to be done to see the sustainability index of both. Keywords: banana chips, LCA, simapro, vacuum frying

Abstract

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.

Abstract

Indonesia's coffee production will reach 774.6 thousand tons in 2021, an increase of 2.75% from 2020, which was 753.9 thousand tons, and is the highest in the last decade and is expected to increase threefold in 2050. Hence, the evaluating environmental performance of the coffee agroindustry is essential if it is to become a more sustainable agroindustry. This paper aims to assess environmental performance (energy footprint, water footprint, and carbon footprint) in Gayo Arabica coffee green bean production with different agro-industry models. The method to evaluate environmental performance that can be used to identify indications of sustainability is Life Cycle Assessment (LCA) Method. The study was conducted on coffee production and exporter cooperatives in Central Aceh. Primary data were obtained through interviews with farmers, collectors, huller owners, and cooperative administrators. Secondary data comes from cooperative reports. The LCA study is described in two product systems, the model of 2015 and the model of 2016. The LCA model of 2015 is based on the green bean production system carried out in 2015 which includes water treatment, pulping, collecting, drying, hulling, finishing, and transportation. The LCA model of 2016 is based on the green bean production system carried out in 2016 until now which includes sub-processes for water treatment, pulping, collecting 1, hulling, collecting 2, finishing, and transportation. The results show that the energy footprint of the 2016 model (2.5128 MJ per f.u) is greater than that of the 2015 model (1.2336 MJ per f.u), the water footprint of the 2015 model is the same as the water footprint of the 2016 model product system, namely 0. 0086 m3 per f.u., and the carbon footprint of the 2016 model (1.93 kg CO2-eq per f.u) is greater than that of the 2015 model (1.48 kg CO2-eq per f.u). The cooperative initiative (in the model of 2016) is for the purpose of process improvement but cannot reduce carbon emissions. To reduce emissions from the use of fossil fuels, it is necessary to optimize land transportation routes and energy efficiency.

Abstract

Human Resources have an important role and become the key to success in carrying out activities to achieve the vision and mission of the organization. HR problems in Government Agencies are not only in HR Professionalism. In addition, organizational changes need to be made to face national development and global competition. In organizational changes, employee placement based on qualifications, competencies and performance needs to be done properly so that employee professionalism is maintained. The purpose of this study is to find employee placement strategies based on the merit system at the Directorate of Health Worker Development and Supervision to run optimally. This study used a descriptive method of qualitative approach with data collection using observation, interviews, and documentation. The number of informants in this study was 5 people with data analysis techniques using data reduction, data presentation, and conclusions. The results of this study state that the placement of employees based on the merit system has not run optimally, there are still problems including there are employees who have not been improved in competence, performance appraisals have not been consistently carried out based on organizational and employee performance targets, and have not carried out competency development mapping based on performance and competency gaps. The age factor is still a consideration in employee placement so that the application in the concept of performance achievement has not been carried out optimally. The resulting strategy is by mapping and improving competency development based on competency and performance gaps, conducting objective and measurable performance appraisals based on organizational and employee performance goals, changing organizational culture and implementing talent management in accordance with applicable regulations.

Abstract

The Radial Basis Function (RBF) neural network has been widely applied for approximating nonlinear systems and improving control robustness, particularly in uncertain conditions such as dynamic shifts in the quadrotor’s Center of Gravity (COG). However, initial weight estimation errors can degrade transient responses, reducing tracking performance. This study proposes a novel RBF-based control scheme integrated with a performance-bound mechanism to enhance quadrotor stability under COG uncertainty. The performance bound ensures that the quadrotor’s motion remains within a defined region around the reference trajectory, thereby minimizing steady-state and transient errors. The RBF network is trained online to estimate the system’s dynamic changes, and the controller is designed using a Lyapunov-like function to ensure stability. Simulation results show that the proposed controller achieves better tracking accuracy and significantly lower energy usage, with total force and moment values reduced compared to the standard RBF controller. Specifically, the proposed controller uses 3010.7 N of force and 2.2427 Nm of moment, while the standard controller requires 3150.2 N and 15.197 Nm. These results confirm that the proposed method provides improved performance and energy efficiency. This research highlights the potential of integrating performance bounds in neural network control for robust quadrotor navigation. Future work includes real-world experiments to validate performance under varying COG perturbations.
