Abstract

The tidal dynamics of water affect not only the layers on the surface of the seas but also the entire water mass. The Tabanio River is a tidal-influenced water area with the highest utilisation level in Tanah Laut. Water quality at the estuaries of Tabanio and Panjaratan River is affected by various human activities, such as fishing, plantations, transportation, and waste disposal. This study aims to compare water quality at high and low tides and test the relationship between tidal changes and fluctuations in water quality parameters in both locations. The data used are the results of measurements on July 3 and July 22, 2024, during high and low tide conditions. The relationship between water quality values and tides was analyzed descriptively, then compared with water quality standards according to Government Regulation of the Republic of Indonesia Number 22 of 2021 class 1 and continued with the ANOVA test. Low tide conditions bring to increase in the parameters of conductivity, current, temperature, pH, salinity, and TDS at all locations, while turbidity is only in the estuary. Tidal conditions influence oxygen deficits in all sites, while nitrite and nitrate tend to increase. TSS parameters exceed quality standards in Panjaratan, while Cu and COD exceed quality standards in Tabanio.

Abstract

Penggunaan teknologi saat ini sudah banyak dilakukan dan disemua bidang, dan mendukung banyak kegiatan masyarakat. Pembelajaran di era merdeka belajar bisa dilakukan tanpa terbatas ruang, waktu, dan wilayah. Kegiatan pengabdian ini dilakukan untuk mensosialisasikan penggunaan internet sebagai media pembelajaran di masyarakat sebagai bagian pendidikan di rumah dan lingkungan. Kegiatan pengabdian kepada masyarakat dilaksanakan di Desa Karang Indah Kecamatan Mandastana Kabupaten Barito Kuala. Pada kegiatan disampaikan beberapa aplikasi online yang bisa digunakan sebagai media pembelajaran bagi masyarakat baik penggunaan individua tau sebagai orang tua. Kegiatan ini juga memberikan pengetahuan penggunaan internet sebagai media sosial dan dampak positif atau negatif dari internet. Kegiatan diikuti oleh unsur desa dan masyarakat Desa Karang Indah, dan hasil yang dicapai adalah masyarakat semakin mengetahui dan memahami internet sebagai media pembelajaran dengan berbagai aplikasi seperti canva dan media-media sosial lainnya.

Abstract

Plastics become debris in the ocean that can be broken down into tiny particles of micro size (<5 mm) and scattered into columns to the bottom of the water. Its very small size makes it easily accessible to various aquatic organisms, such as plankton, crustacean, and mussel. There have been many studies use mussel as a bioindicator for microplastic pollution but no one has observed the effect of microplastic exposure to mussel mortality. The aim of study was to examine the effect of microplastic on mussel mortality. Green mussels were collected from Mandalle Waters, Pangkep Regency (Pangkajene Kepualauan) then were exposed to microplastic polyethylene originating from shieving of scrub soap. The exposure was carried out for 7 days with microplastic concentrations of 0.05 (A), 0.5 (B), and 5 (C) g/L. Statistical test results showed the treatment B and C were not significantly different, but the two treatment were significantly different from treatment A. The percentage of green mussel mortality during the experiment increased with increasing microplastic concentrations with the percentage of mortality exceeding 80% at treatment C.
