Abstract

Flood risk assessment plays a crucial role in determining flood hazard zones and formulating effective mitigation strategies. Using a multi- criteria decision support system, this study focuses on evaluating the flood risk index within the Bolon Watershed (DAS Bolon). Geographic Information Systems (GIS) were employed as an effective disaster mitigation tool to provide comprehensive geospatial data. The research integrates the Cellular Automata–Markov Chain (CA–MC) model using the MOLUSCE plugin in QGIS to spatially project land-use change analysis, the Analytical Hierarchy Process (AHP) to determine variable weights influencing flood risk, and Weighted Multi-Criteria Analysis (WMCA) for spatial flood zonation assessment. Between 2017 and 2021, significant land-cover changes occurred in the Bolon Watershed, with 67.55 km² converted into residential areas. Forest deforestation began in 2017 and is projected to continue until 2033, potentially disrupting the hydrological cycle and intensifying flood-prone zones. As a result, the flood-prone residential area increased markedly from 1.4% (2017) to 2.89% (2021) and is projected to reach 4.74% by 2033, with an average annual increase of 0.21%. This study underscores the importance of improved land-cover management to mitigate flood zonation in the Bolon Watershed. It also emphasizes the need for strict enforcement of spatial planning and zoning regulations, as well as enhanced monitoring and legal measures against land-use conversion particularly in flood-prone and water recharge areas.

Abstract

Plantation crops remain a central choice for many farmers because of their promising yields, and clove is among the most valued due to its strong market demand. Despite this potential, clove cultivation frequently faces constraints, particularly sudden stem bud decline and disease susceptibility. These problems often arise from land that does not meet the crop’s ecological requirements, yet many farmers still find it difficult to obtain reliable and timely information on land suitability. Spatial data offers an effective solution because it provides rapid and up to date insights into environmental conditions without requiring farmers to visit each site. When combined with big data and smart farming technologies, spatial information becomes even more useful, since farmers can monitor climate patterns, soil temperature and soil texture more easily.This study aims to generate accurate information on land suitability for clove cultivation through spatial big data and to demonstrate the role of smart farming systems in detecting suitability levels. Using a quantitative approach, land conditions were classified into four suitability categories which include very suitable, suitable, marginal and not suitable. Landsat imagery from Sinjai Regency in 2024 identified approximately 24,566 pixels or 2,282 hectares of land used for clove cultivation. These areas were concentrated in South Sinjai, Central Sinjai, Sinjai Borong and West Sinjai. Additional land cover classes consisted of primary forest, rice fields, settlements, secondary forest, annual crops and mixed plantations. The classification results were supported by categorical accuracy testing, highlighting the need to evaluate each land use type individually to ensure the reliability of the spatial interpretation.

Abstract

This study aims to evaluate the effect of adding green mussel shell powder (CKH) on the fire resistance of Fiberglass composite materials used in fishing vessel hulls under 5 GT. The composite was made using the hand lay-up method with variations in CKH composition of 0%, 10%, 20%, 30%, 40%, and 50%. Testing was carried out using the ASTM D635 standard to determine the burning rate. Statistical analysis using logistic regression to determine the linear relationship between variables. Statistically, logistic regression states a p-value <0.05 and is suitable as a reference model to determine the value of CKH powder composition with the burning rate of the material. This study shows that specimens with the addition of 20% CKH increase fire resistance by 8.56% (13.10 mm/min), while the addition of 50% CKH increases up to 19.92% (11.47 mm/min). So that the more CKH composition additions can increase the fire resistance of the material. These results indicate that CKH waste has the potential as an environmentally friendly additive that improves ship safety.

Abstract

The challenge faced by fishermen involved in lobster fishing is the decline in population due to overfishing and unsustainable practices. Intensive lobster fishing can disrupt the balance of the ecosystem, especially if the fishing gear used is not environmentally friendly. Lost fishing gear can continue to catch lobsters and other species unintentionally, a phenomenon known as ghost fishing. The methods applied in this research include literature review and experimental design. The literature review was conducted by examining data and the development of lobster traps from research publications and various books related to fishing. The analysis of the development of existing trap designs before the modification process is a key factor in selecting the standard trap design. This aims to develop lobster traps that are selective for legal sizes. The tiered wall trap has two entrances, one at the top in the shape of a cylinder with a width of 15 cm and a length of 20 cm, cylindrical in shape and without any hole patterns. It is expected that the trapped lobsters will not be able to escape because the length of the entrance itself is longer than the leg size of the catchable lobsters, where lobsters with a carapace length of 8.3 cm have a front leg length of 8 cm, making it impossible for the caught lobsters to climb out. The design of the tiered wall trap with a perforated pattern on the base of the trap at 8 cm is expected to allow catchable lobsters to climb into the trap's mouth. The tiered walls help lobsters to easily climb up to the mouth, thereby increasing the effectiveness and selectivity of the trap for catchable-sized lobsters. However, this design still needs to be tested in lobster catching areas or in laboratory scale.

Abstract

The rearing of Mojosari ducks in Indonesia has become increasingly important as an alternative source of animal protein. However, the high cholesterol content in duck meat presents a challenge to its consumption. This study aims to evaluate the effect of turmeric supplementation in feed on cholesterol levels in the liver, blood, and meat of Mojosari ducks, as well as the organoleptic quality of the resulting meat. The experiment utilized a factorial Randomized Completely Block Design (RCBD), where ducks were divided into four treatment groups based on turmeric dosage: 0%, 6%, 8%, and 10%. Parameters measured included cholesterol levels in the liver, blood, and meat, as well as organoleptic assessments of taste, aroma, texture, color, and tenderness of the meat. The results indicated that turmeric supplementation significantly reduced cholesterol levels in the liver, blood, and meat of the ducks, with the 8% and 10% turmeric groups showing the lowest cholesterol levels. Turmeric supplementation also improved the tenderness and color quality of the duck meat, although no significant differences were observed in taste and aroma. The reduction in cholesterol levels suggests the potential of turmeric as an effective feed additive for producing healthier duck meat that is more appealing to consumers. These findings have implications for the development of feed based on natural ingredients that can enhance duck meat quality and support the sustainability of the duck farming industry in Indonesia.

Abstract

In 2021, the service coverage of PDAM Tirtanadi’s water supply system reached 73.3%. To further improve the service capacity, a new raw water source was developed through the construction of the Mebidang Regional Water Supply System (SPAM), which draws water from the Bingei River in Binjai City. The PDAM Tirtanadi branches directly affected by this change in raw water source include the Sei Agul and Diski branches. This study aims to evaluate customer satisfaction levels with the water product quality and service performance of the Mebidang SPAM at PDAM Tirtanadi. The methods employed include the Customer Satisfaction Index (CSI) and Importance and Performance Analysis (IPA). Data were collected through questionnaires distributed to both existing customers and new service connections at the Diski and Sei Agul branches of PDAM Tirtanadi. The results showed that customer satisfaction levels were as follows: long-term customers at the Diski branch scored 83.56%, new connections at Diski 83.57%, long-term customers at Sei Agul 82.78%, and new connections at Sei Agul 92.26%. These results indicate that both long-term and new customers at the Diski and Sei Agul branches are generally satisfied with the overall service quality. Based on the IPA results, the main priority for improvement at the Diski branch concerns the imbalance between the cost paid by customers and the volume of water received. Meanwhile, for the Sei Agul branch, variables categorized as low performance and low importance but still of lower priority include PDAM’s responsiveness to customer requests, such as for new connections or meter repairs.

Abstract

Indonesia, as an archipelagic country, holds great potential in marine and fisheries resources. Whiteleg shrimp (Litopenaeus vannamei) is one of the most economically valuable aquaculture commodities, with production reaching 5,812.2 thousand tons in 2020, an increase of 52.8% compared to 2015. However, disease outbreaks remain a major challenge in shrimp farming. One common disease is vibriosis, caused by Vibrio sp., an opportunistic, highly virulent, Gram-negative and facultative anaerobic bacterium. Therefore, early detection of Vibrio abundance is essential for prevention and control efforts. This Final Internship Project (KPA), titled “Abundance of Vibrio Bacteria in Whiteleg Shrimp Culture Media,” aimed to determine the abundance of Vibrio sp. in shrimp ponds and analyze the influence of water quality parameters (NH₃, NO₂, and plankton). The internship was conducted from February 6 to April 17, 2025, at PT Parigi Aquakultura Prima, Central Sulawesi. Activities included water sampling, NH₃ and NO₂ testing, plankton density measurement, sterilization, TCBS media preparation, bacterial inoculation, and enumeration. Observations were carried out in six pond plots with weekly sampling from Day of Culture (DOC) 9 to 79. The regression model obtained was Y = 164.808 + 153.951X₁ + 2092.103X₂ + 0.000X₃, indicating that increasing NH₃ and NO₂ levels positively contribute to Vibrio abundance, each raising bacterial numbers by 153,951 and 2,092,103 units per one-unit increase, respectively. Plankton showed no significant effect. Thus, NH₃, NO₂, and plankton have partial influence on Vibrio abundance, although plankton contributes minimally.

Abstract

The Medan City Government plans to make infrastructure changes by building underpass at the existing signalized intersection between Road Ir. H. Juanda and Road Brigjend. Katamso to reduce traffic congestion. In recent years, vehicle emissions have become a global concern due to their significant impact on public health and environmental quality. As road traffic and vehicle numbers continue to grow, transportation has become a key contributor to air pollution from vehicle exhaust emissions. Consequently, it is essential to assess whether the infrastructure changes from signalized intersection to underpass have an impact on vehicle exhaust emissions. The impact analysis of infrastructure changes on vehicle exhaust emissions is evaluated through traffic simulation using PTV Vissim software with two scenarios, namely the do nothing scenario (existing signalized intersection) and the do something scenario (underpass) ), focusing on CO, NOx, and VOC emissions. The comparative results indicate substantial changes: CO emissions declined by 42.5% (from 40,991 grams to 23,567 grams), VOC by 37.1% (from 9,500 grams to 5,975 grams), while NOx emissions increased by 23.3% (from 7,075 grams to 8,725 grams). These findings suggest that the infrastructure changes from signalized intersection to underpass can positively influence air quality by reducing specific pollutants. However, further studies are necessary to examine its broader impact on other types of vehicle exhaust emissions using diverse emission categories, multiple calculation approaches, and various analytical methods for comprehensive comparison.

Abstract

The potato processing industry in Indonesia continues to face high market demand, while domestic production remains insufficient (reaching only 1.22 million tons in 2023), resulting in dependence on imported raw materials. The expansion of industrial potato cultivation in medium-altitude regions offers considerable potential due to land availability; however, it is constrained by high-temperature stress, requiring varieties that are both tolerant and high yielding. This study aimed to evaluate the growth response and yield performance of three industrial potato varieties Ventury Agrihorti (local), Atlantik (introduced), and Bliss/Chitra (introduced) under two contrasting altitude conditions: medium altitude (600 masl) and high altitude (1500 masl). The experiment employed a Split Plot Design, with observations covering growth parameters, yield components, and tuber quality indicators, including tuber specific gravity (SG). The results revealed a significant interaction between altitude and variety on several parameters, such as plant height, specific leaf weight, number of tubers, and tuber weight per plant. At medium altitude (600 masl), the Atlantik variety demonstrated the best performance, achieving a productivity of 40.39 t/ha with the highest tuber weight. However, Atlantik produced a high proportion of oversize tubers (41.97%), which does not meet industry grading standards. Conversely, at high altitude (1500 masl), Bliss/Chitra showed superior yield performance with a productivity of 42.96 t/ha, followed by Ventury at 38.46 t/ha. Ventury and Bliss/Chitra also excelled in tuber size distribution, producing the majority of tubers (approximately 94–95%) within the Normal category (Ø 4.5–9 cm), which aligns with industrial processing requirements in both altitude conditions. The specific gravity (SG) values of all three varieties ranged from 1.08 to 1.09, indicating compliance with the minimum quality threshold for potato processing industries (>1.08).

Abstract

The circular economy has emerged as an important approach to enhancing agribusiness sustainability by shifting production systems from linear models toward regenerative processes that preserve resource value. This study identifies and evaluates the implementation of an integrated livestock farming system in agribusiness micro, small, and medium enterprises through a case study of CV Mitra Tani Farm, an integrated livestock-based enterprise in Indonesia. Circular agribusiness practices were identified using the 9R principles, and the analysis employed the Triple Bottom Line framework to assess sustainability performance across economic, environmental, and social dimensions. The identification results indicate that the integrated farming system implemented at MT Farm operationally reflects the core principles of the circular economy. The evaluation further shows that circular practices such as waste-to-resource conversion, integrated farming systems, and product diversification effectively reduce operational waste, improve resource efficiency, and maintain ecological balance. Socially, these practices promote employment creation, partner capacity building, and the strengthening of rural collaboration. From an economic perspective, circular practices enhance business resilience; however, the economic potential of waste-based activities has not yet been fully optimized, indicating the need for further development to enable the circular economy to play a more effective role in supporting the transformation toward sustainable agribusiness.
