Abstract

Trade and tourism activities in Telaga Kumpe can increase the input of organic matter into the waters which results in increased fertility, decreased function and changes in water quality so that it has an impact on the community structure of plankton as one of the aquatic organisms. This study aims to determine the abundance, diversity, uniformity and dominance of plankton before sunrise (morning) and after sunrise (afternoon) as well as differences in the ratio of plankton abundance before sunrise and after sunrise (afternoon) in Kumpe Lake. . The research was carried out at three sampling points, namely at the inlet, in the middle of the lake and at the outlet. The main parameters measured included the number of individuals and plankton species, while the supporting parameters included physico-chemical factors in the waters, namely water temperature, light intensity, depth, pH and TDS levels. The results showed that the highest abundance of phytoplankton were Microcystis aeruginosa and Mougeotia viridis, while the highest abundance of zooplankton were Diaptomus siciloides and Cyclops vicinus. The diversity of plankton in the morning is included in the medium category, in the afternoon the low to moderate category. The uniformity of plankton in the morning and afternoon is in the low to high category. The plankton dominance index value in the morning indicates a dominant species, whereas during the afternoon it does not indicate a dominant species. The dominating species are Microcystis aeruginosa, Mougeotia viridis, Diaptomus siciloides and Cyclops vicinus. The results also show that the abundance of phytoplankton is higher during the day, and the abundance of zooplankton is higher in the morning

Abstract

Pestisida merupakan zat kimia yang digunakan oleh bidang pertanian untuk melindungi tanaman dari serangan hama. Namun, kehadiran pestisida memiliki dampak negatif bagi lingkungan, kesehatan manusia, dan organisme yang hidup di sekitar tempat yang terpapar pestisida secara jangka panjang. Pada lahan pertanian, penggunaan pestisida menyebabkan residu pestisida terakumulasi di air sungai. Sehingga hanya organisme tertentu saja yang dapat bertahan hidup, salah satunya fungi. Penelitian menggunakan air sungai yang diambil sebagai sampel dan dilakukan isolasi untuk mendapatkan fungi yang berpotensi untuk mendegradasi pestisida. Uji potensi fungi dilakukan dengan penanaman fungi hasil isolasi dan pemurnian ke campuran media PDA (Potato Dextrose Agar) dan klorpirifos, pengukuran diamater koloni yang tumbuh pada media tersebut, dan identifikasi fungi sampai tahap genus yang memiliki potensi besar dalam mendegradasi pestisida. Lokasi pengambilan sampel berada di enam titik stasiun Sungai Mengaji dan Prukut Kabupaten Banyumas. Lokasi analisis sampel berada di Laboratorium Mikologi dan Fitopatologi Fakultas Biologi Universitas Jenderal Soedirman. Tujuan dilakukannya penelitian ini adalah memperoleh isolat fungi dari sungai Mengaji dan Prukut Kabupaten Banyumas, mendeteksi kemampuan fungi dalam mendegradasi pestisida, dan mengetahui genus isolat terbaik dalam mendegradasi pestisida. Isolat fungi yang diperoleh dari keenam stasiun Sungai Mengaji dan Prukut Kabupaten Banyumas terdiri dari 25 isolat yaitu F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12, F13, F14, F15, F16, F17, F18, F19, F20, F21, F22, F23, F24, dan F25. Isolat fungi asal Sungai Mengaji dan Prukut Kabupaten Banyumas yang memiliki kemampuan tinggi dalam mendegradasi pestisida antara lain F12, F21, F24, dan F25. Genus isolat terbaik dalam mendegradasi pestisida setelah dilakukan identifikasi secara makroskopis dan mikroskopis adalah Trichoderma sp.

Abstract

River Mengaji originates from a water source on the southern forest slopes of Mount Slamet. Gastropods are important biotic components in river ecosystems and can be used as bioindicators due to their sensitivity to water quality changes. Gastropod abundance is closely related to the physical and chemical parameters of water quality. This study aimed to determine the abundance of gastropods, water quality, and the relationship between gastropod abundance and water quality in River Mengaji, Banyumas Regency. Species gastropod identified samples collected. The relationship between gastropod abundance and water quality was analyzed using Spearman's Rank Correlation. The result showed that the gastropods found in Sungai Mengaji consist of five species, namely Melanoides tuberculata, Sulcosprira testudinaria, Radix rubiginosa, Tarebia granifera, and Filopaludina javanica. The highest abundance of gastropods was observed at Station IV, followed by Stations II, III, and I. Water quality conditions were generally good enough, except for temperature and BOD at Station IV. The high abundance of F. javanica at Station IV is related to the high temperature and BOD conditions in Sungai Mengaji, Banyumas Regency.

Abstract

Discussions related to the implementation of Corporate Social Responsibility (CSR) programs are often not accompanied by the impact produced, this often makes the implementation of CSR only limited to charity activities without having an impact on the community in a sustainable manner. The empowerment-based CSR approach model is one of the options in the implementation of programs that are considered to be able to increase the role of the community and make it a subject and not just an object. This research is a qualitative research by taking primary data through observation and interview activities, while secondary data is sourced from supporting documents found in the field. Using an environmental ecology approach, this study looks not only at natural phenomena, but also investigates how human activities can affect the balance of ecosystems and the quality of the environment. The results of this study show that the CSR program has had an impact on 4 main dimensions, namely: the natural dimension, the economic dimension, the social dimension and the wellbeing dimension.

Abstract

The Sebuku River has an important role for the life of flora, fauna, and local communities in Nunukan Regency, North Kalimantan Province. Mining activities in this area raise concerns about potential water pollution. This study aimed to evaluate the impact of mining activities on the water quality of the Sebuku River. Sampling was carried out by purposive sampling at five observation stations between ST-1 and ST-5 based on predetermined coordinate points. The parameters tested included temperature, TSS, pH, DO, BOD, COD, NO₃, PO₄, CN⁻, and fecal coliform. The analysis method referred to SNI and the results are compared with class II river water quality standards in Appendix VI of Government Regulation of the Republic of Indonesia Number 22 of 2021. The results of the analysis showed that the TSS level of all stations exceeded the quality standard as the majority of respondents who stated that it was cloudy, but the level tended to decrease downstream. The highest COD parameters were detected in ST-2. This is supported by the value of the Pollution Index (PI) that indicated it as the primary pollution source from mining activities. The rest of the parameters are still within the permissible limits. Overall, the water quality of the Sebuku River is still classified as moderate based on the value of the Water Quality Index (WQI).
