Abstract

Antioxidants and lipid markers have gained significant attention in recent decades for their pivotal role in promoting overall health and well-being. On other hand, the improper disposal of industrial effluents has emerged as a major environmental challenge leading to contamination of water sources that subsequently impact public health. Estimation of the effect of contaminated water by the residents of brick kilns on the level of antioxidants (CAT, GPX, and SOD), lipid peroxidation MDA, and lipid profile (TC, HDL, LDL, and TG). A total of 30 surface water samples were collected from the areas near the brick kilns located in Al-Hai, Al-Kut, and Badra cities into labeled plastic containers. Then, overall 60 rats were divided equally into two groups; the 1st was given tap water (negative control), and the 2nd was given the contaminated water (experimental). After 75 days, blood was collected from all animals to obtain the sera that tested using the specific species quantitative enzyme-linked sorbent assay (ELISA) kits to measure the concentration of antioxidants, lipid peroxidation and lipid profile. In comparison to values of control group, results of antioxidants including CAT (5.419 ± 0.363 pg/ml), GPX (24.533 ± 1.317 IU/ml) and SOD (4.013 ± 0.479 U/ml) were reduced significantly; while significant increases were shown in results of lipid peroxidation MDA (187.333 ± 10.402 ng/ml), as well as in LDL (641.611 ± 54.809 ng/ml). However, insignificant variation between the values of experimental and control groups was seen in values of TC (3.528 ± 0.332 nmol/ml), HDL (36.283 ± 1.881 ng/ml), and TG (567.556 ± 72.724 ng/ml).

Abstract

Flooding is one of the causes of environmental damage worldwide. Several things that can affect flooding in urban areas, Palembang experiences periodic flooding problems, especially every rainy season. The data in this article consists of primary data obtained from location surveys in retention ponds, including: documentation, topography, depth of retention ponds and secondary data from related agencies, including: location maps, climatology, regional topography. Palembang City has varying levels of flood vulnerability: high (Jakabaring, Kertapati, Plaju, and Seberang Ulu), medium (Ilir Barat and Sukarame), and low (Alang-Alang Lebar). Lowland areas with poor drainage systems require more attention. Retention ponds play an important role in managing rainwater runoff, such as the Jakabaring Sports Hall (200,000 m²), Ogan Permai Indah (22,217 m²), and Brimob Demang Lebar Daun (30,000 m²). The city's topography, which is mostly flat and low, especially around the Musi River, further increases the risk of flooding.

Abstract

Forest fires are a common ecosystem disturbance globally and have a significant impact on the environment and human life. Ecologically, fires result in decreased land productivity, loss of forest economic value, and threats to biodiversity. The study was conducted quantitatively and qualitatively with secondary and primary data. The data shows fluctuations in the number of hotspots and the area of burned land from 2019 to 2024. Major fires occurred in 2019 and 2023, while a significant decline was seen in 2020 and 2024. This decline reflects the effectiveness of fire mitigation involving the government and the community. Efforts that have been made to reduce the risk of forest and land fires in OKI Regency include peatland rewetting, community education, peatland-based economic empowerment, joint patrols, and the active role of the Fire Aware Community (MAPI) group. The use of satellite-based monitoring technology is also an important step in fire monitoring and mitigation. Preventing forest and land fires in the future requires a comprehensive and sustainable approach, including law enforcement against illegal land burning, increasing patrols, and strengthening community education. Collaboration between stakeholders such as BPBD, local governments, communities, and the private sector is very important to maintain the stability of forest and land fire reduction in the OKI region.

Abstract

The present research determines the financial practicality of skipjack tuna (Katsuwonus pelamis) fishing unit establishments located in the Flores Sea portion of South Sulawesi. A survey-based research project took place between September and December 2024 to obtain data from Bulukumba and the Selayar Islands regencies through random sampling procedures. The research relied on interview sessions together with questionnaires and observations as well as literature review for data collection. The financial assessment performed a cost breakdown followed by income evaluation using NPV with IRR and Net B/C and PP calculations. The skipjack tuna fishing businesses employing purse seine gear in the Flores Sea operate at a profitable level. Financial analysis demonstrates profitability and sustainability potential because the regencies achieved positive NPV and IRR exceeding interest rates together with Net B/C Ratio values higher than one and PP that lasts for less than three years. The research results validate ongoing support for the skipjack tuna fishing industry throughout the region.

Abstract

Processing potatoes into flour is one way to reduce the risk of damage and extend the shelf life of potatoes. Potato flour has high absorption, fine texture, sweet taste, and a distinctive fragrant aroma. Cookies are dry baked goods produced by baking dough made from wheat flour, either with or without substitutes, along with oil or fat, and optionally incorporating other food ingredients and approved additives. Based on this, it is necessary to conduct research on potato flour formulations in cookies with organoleptic tests to determine the best formulation for making cookies from potato peel flour, obtaining the best formulation it can reduce the dependence of the community and industry on the use of wheat flour. The research used a Completely Randomized Design (CRD) with four formulations (0%, 25%, 50%, and 75% potato peel flour substitution) and two repetitions. Organoleptic testing, including hedonic and hedonic quality assessments, was conducted to evaluate panellists' preferences for colour, texture, taste, and aroma. The results showed that cookies with 25% potato peel flour substitution (F1) were the most preferred, achieving the highest scores in all sensory attributes. However, increasing the substitution level resulted in a darker colour, firmer texture, and a more pronounced bitter taste, affecting overall acceptability.

Abstract

Green mussel (Perna viridis) is a marine organism that is widely cultivated and considered a leading commodity in the fisheries sector. The increase in mussel production has resulted in a significant amount of shell waste. Improperly managed mussel shell waste can have a negative impact on the environment. However, green mussel shell waste has great potential for reuse, one of which is as a composite material in fiberglass manufacturing. The high calcium content in mussel shells can serve as an additional reinforcement in fiberglass composites. The wood crisis as a raw material for boat construction, which also contributes to environmental deforestation, has led to the consideration of alternative materials such as fiberglass for boat building. This research is an experimental study on the utilization of green mussel shell (GMS) waste as a fiberglass mixture material for boat construction. An ideal composition between the GMS waste powder and fiberglass material is expected to enhance the mechanical strength of fiberglass fishing boats. The study shows that the addition of 20% GMS powder in fiberglass lamination improves mechanical properties, with a maximum tensile stress value of 113.23 MPa. Meanwhile, the maximum flexural strength is observed at 15% GMS powder composition, reaching 192.38 MPa. The addition of GMS powder has the potential to strengthen fiberglass, making it suitable for applications such as fishing boat hulls. However, adding more than 30% GMS powder decreases the material’s strength, particularly in tensile testing. Further research is needed to explore the use of GMS powder for waste reduction and to provide insights into its applications in fiberglass boat manufacturing.

Abstract

The urgency of this research lies in the need for a scientific-based solution in understanding the pattern of runoff and flood inundation to support effective mitigation planning. This study aims to analyze the characteristics of the Tallo River runoff before and after infrastructure development; identify the main factors causing flood inundation in the affected area and develop flood mitigation strategies based on hydrological and hydraulic modeling. The methods used include data collection using 15 years of rainfall data (2010–2024), topographic maps (DEM), and land use information; hydrological analysis by calculating the design flood discharge using the Rational and Nakayasu methods; hydraulic modeling with HEC-RAS 2D flood inundation simulation to understand the pattern of inundation distribution due to increasing runoff discharge; evaluation of the impact of development by comparing the runoff discharge before and after development and identifying its contribution to flood risk and mitigation strategies by compiling technical recommendations such as raising the embankment, improving drainage, and increasing the elevation of the affected area. The results of the study indicate that flooding in the Tallo River is mainly caused by the river's inability to accommodate the runoff discharge and the backwater effect of the urban drainage system. The increase in discharge due to the construction of a shopping center was recorded as very small (0.84 m³/second) and was not significant to the occurrence of flooding. The proposed mitigation strategies include building a 2.5-meter high embankment, increasing drainage capacity, and regulating the elevation of the affected area.
