Abstract

The purpose of this study was to determine the condition of water quality and water pollution conditions in the Pundul River, Kutasari. The research location, namely station 1 is at coordinates -7.363170 LS and 109.335832 BT, station 2 -7.364296 LS and 109.337737 BT, station 3 -7.366209 LS and 109.338324 BT, station 4 -7.368257 LS and 109.340588 BT, and station 5 -7.369092 LS and 109.340915 BT. The data collection method used is the observation method with a quantitative approach (using the STORET and CCME-WQI methods) and qualitative (comparison of sample data with PP No.22 of 2021). The parameters used are temperature, pH, DO, COD, BOD, and total coliform. Parameters that do not meet the class III quality standards are pH with results ranging from 5.37-6.37 and total coliform with a range of 3,500 - 2,400,000 MPN / 100 ml. The data analysis used is the STORET and CCME-WQI methods. Based on the results of the pollution analysis, the Pundul River flow is in the moderately polluted category with a value of -17 and the most polluted station is at station 2 due to direct waste discharge from vermicelli noodle producers. The results of the analysis of the water quality standard status in the Pundul River flow are still in the less category with an average value of 54.14, so it is still in poor condition for tilapia fish farming activities in Kutasari District, Purbalingga.

Abstract

Stunting menjadi salah satu masalah gizi utama di Indonesia yang berdampak pada pertumbuhan fisik, perkembangan kognitif, dan kualitas sumber daya manusia di masa depan. Salah satu strategi pencegahan stunting adalah melalui peningkatan konsumsi ikan sebagai sumber protein hewani yang berkualitas. Tim pengabdian Universitas Tidar melaksanakan kegiatan “Penyuluhan dan Demo Masak dalam Upaya Gerakan Makan Ikan (GEMARI) untuk Mencegah Stunting di Desa Bandongan, Kabupaten Magelang”. Kegiata ini bertujuan untuk meningkatkan pengetahuan masyarakat mengenai pentingnya konsumsi ikan serta memberikan keterampilan praktis dalam mengolah ikan menjadi produk bergizi. Metode pelaksanaan meliputi ceramah interaktif, diskusi kelompok, serta demonstrasi pengolahan ikan menjadi produk samosa. Evaluasi keberhasilan kegiatan dilakukan melalui pre-test dan post-test untuk mengukur peningkatan pengetahuan peserta, serta observasi selama kegiatan berlangsung. Hasil evaluasi menunjukkan adanya peningkatan pengetahuan yang signifikan melalui hasil post-test menunjukkan 100% peserta memahami pentingnya konsumsi ikan dan cara pengolahannya dengan benar. Selain itu, peserta menunjukkan antusiasme tinggi dalam mengikuti demo masak dan menilai kegiatan ini bermanfaat bagi upaya pencegahan stunting. Kegiatan ini berpotensi untuk direplikasi secara berkelanjutan dengan melibatkan berbagai pihak guna memperluas dampak dalam mendukung upaya penurunan angka stunting.

Abstract

Eels are catadromous fish that utilize river systems, especially estuaries, as migration corridors from marine to upstream habitats. This study assessed the abundance potential and spatial distribution of eels in the Luk Ulo River, Kebumen Regency, to support conservation efforts. Sampling was conducted at 10 stations from upstream areas to the estuary. Analyses included morphometric identification, spatial distribution, length–weight relationships, growth modeling, Principal Component Analysis, and cross-correlation with environmental parameters. A total of 30 individuals were collected, consisting of two species: Anguilla bicolor bicolor (22 individuals) and A. marmorata (8 individuals). Most specimens (93.54%) were in the yellow eel phase, indicating a growth stage dominance, while 6.45% were elvers. The mean length was 49.90 cm (SD = 34.95 cm), with non-normal distribution (p < 0.05) and dominance in the 32–48 cm size class. Growth followed a negative allometric pattern (W = 0.00083L2.87), where length increases faster than weight, with a high determination coefficient (R² ≈ 0.93), indicating a strong relationship between length and weight. The population structure suggests that the Luk Ulo River primarily functions as a growth habitat with stable environmental conditions. Cross-correlation analysis showed strong positive relationships between eel abundance and salinity (r > 0.81), total dissolved solids (r > 0.79), and phosphate (r > 0.61), indicating that higher values of these parameters are associated with increased eel presence.
