Abstract

Plankton serves as a bioindicator that can be used as a marker for water quality related to water saprobity index. Way Awi River is a river flowing from the Susunan Baru area, passing through the Tandjungkarang region, and reaching the Garuntang area. Liquid waste from households is often directly discharged into the river, without passing through a containment system such as a septic tank, resulting in river pollution. To understand this relationship, this research was conducted to determine the biological condition of the Way Awi River based on plankton community structure, including abundance index, diversity index, evenness index, and dominance index, as well as its correlation with water quality using Pearson correlation test. The research was conducted in the Way Awi River with sampling taken at five different stations from October to December 2023. Water samples were analyzed using physical parameters including water temperature and turbidity, while chemical parameters observed were pH, DO, BOD, and COD. Based on the analysis of plankton community structure, it was found that the water of Way Awi River is in a moderately polluted condition.

Abstract

This study aims to analyze the effect of liquid organic fertilizer (POC) from tofu waste on the growth of tomatoes (Solanum lycopersicum Mill.). The study was conducted in September - December 2024 at the Green House of the Faculty of Science and Technology, Universitas PGRI Palembang. Data were analyzed at the Biology Laboratory of the Business Science Center, Universitas PGRI Palembang. Data were obtained quantitatively using analysis of variance (ANOVA). The experimental design used was a Completely Randomized Design (CRD) with 6 treatments and 4 repetitions. The treatments in this study were the administration of liquid tofu waste fertilizer with concentrations of 0%, 5%, 10%, 15%, 20%, and 25%. The research data obtained were analyzed using Analysis of Variance (ANOVA) at the 5% level, and significantly different treatments were further tested with BNJ at the 5% level. carried out with Honestly Significant Differences (BNJ) at the 5% level. The results showed that liquid organic fertilizer (POC) from tofu liquid waste had no significant effect on the growth of plant height, number of leaves, stem diameter, and wet weight of tomato plants (Solanum lycopersicum Mill). The application of liquid organic fertilizer (POC) from tofu liquid waste with P4 treatment was the best result in all parameters, producing an average plant height of 7.15 cm, number of leaves 5 strands, stem diameter 0.05, and wet weight of tomato plants 0.22 grams.

Abstract

The city of Banjarmasin is highly vulnerable to flooding due to its low-lying geographical conditions, numerous rivers, and significant projections of sea level rise. This study aims to examine the geographical and hydrological factors contributing to flood vulnerability in Banjarmasin, analyze the impacts and flood-affected areas, and evaluate sea level rise projections and the flood management strategies that have been implemented. The research employs a descriptive qualitative method to investigate the causes of flooding and the corresponding mitigation strategies. The findings indicate that flooding is caused by both natural factors and human activities, such as river pollution due to waste and poor drainage systems. Community participation remains low and tends to be seasonal. Flood mitigation efforts need to be strengthened through improved infrastructure, continuous public outreach, and active community involvement.

Abstract

This study aims to analyze the exposure time of the Extremely Low Frequency 300 μT magnetic field on the electrical conductivity of the tempoyak fermentation process. The research method is the experimental method. The research sample was divided into two groups, namely the control group which was not exposed to magnetic fields and the experimental group, namely the group that was given exposure to the Extremely Low Frequency 300 μT magnetic field with a time of 20, 40, and 60 minutes. The data obtained were analyzed by the F test, if the exposure time of the Extremely Low Frequency 300 μT magnetic field had a significant effect, then continued with the BNT test. The results showed that the electrical conductivity value in the experimental group was higher than the control group. The value of electrical conductivity in the control group is 1147 μS/cm, the value of electrical conductivity at 20 minutes exposure is 1156 μS/cm-1268 μS/cm, 40 minutes exposure is 1177 μS/cm 1275 μS/cm, and 60 minutes exposure is 1187 μS/cm-1331 μS/cm. The longer the exposure time to the 300 μT Extremely Low Frequency magnetic field, the higher the tempoyak electrical conductivity value. From the F test that has been carried out, it is found that the exposure time of the Extremely Low Frequency magnetic field significantly affects the value of the tempoyak electrical conductivity (FCount = 26,839 > FTabel = 4,76) with a significant 5%.

Abstract

The Pinus Ciherang area, located in Sukamukti Village, Cisayong District, Tasikmalaya Regency, at the foot of Mount Galunggung, holds great tourism potential, particularly with the presence of beautiful pine forests and the waterfalls Curug Badak and Curug Ciherang. However, this exceptional potential has not been well managed, mainly due to the local community's lack of awareness about the valuable assets in their surroundings. As a result, the area has not developed optimally. To realize this potential and address the issue of unorganized management, a holistic development strategy needs to be implemented. The objective of this study is to formulate a sustainable development strategy for the Pinus Ciherang nature tourism area through the identification of local potentials, community empowerment based on Community Based Tourism (CBT), and the application of the 4A concept (Attraction, Accessibility, Amenity, and Ancillary) along with digital innovation to enhance the local economy. This study uses a literature review method. The approach involves applying the 4A strategy and the principles of Community Based Tourism (CBT). Through the 4A strategy, natural attractions such as pine forests and waterfalls can be optimized, accessibility to the location improved, supporting facilities for tourists provided, and appropriate service institutions established.

Abstract

fisheries are the mainstay of the coastal community's economy, and Sondong fishing gear is still commonly used. Although Sondong is considered effective, it raises ecological concerns because it risks damaging the seabed habitat and produces high bycatch. This study aims to describe fishing communities' perceptions of Sondong fishing gear regarding its effectiveness and impact on fish resources and the environment. The study employed a quantitative descriptive approach with purposive sampling of active fishermen in Sungsang, conducted in November 2024. The results show that fishermen have a strong understanding of Sondong because it has been widely used and passed down informally. They perceive Sondong as an effective and profitable tool, though this perception is changing as catches decline. The ecological impact has not been widely recognized, and regulations tend to be rejected due to economic dependence. As fishermen's perceptions are more oriented toward the economy than ecology, an educational approach is needed to encourage the transition to more sustainable fishing gear.

Abstract

Rivers are vital freshwater ecosystems that play an essential role in maintaining environmental balance and supporting aquatic life. The benthic and planktonic communities serve as bioindicators of water quality and form integral components of the aquatic food web. This study aims to analyze the structure of benthos and plankton communities in the Jemile River, Muara Enim Regency, South Sumatra, and to evaluate their relationship with water quality parameters. The findings revealed the presence of Baetidae larvae, indicating clean and well-oxygenated waters, alongside Chironomidae, which tolerate organically enriched substrates. Among plankton, Brachionus was found as an indicator of eutrophic conditions, and Gyrosigma served as a primary producer. The diversity of organisms observed suggests habitat quality variations influenced by domestic, agricultural, and mining activities around the river. This study highlights the complex ecological dynamics of the Jemile River and underscores the need for continuous monitoring to support sustainable water resource management.
