“…In the middle of the river water sampling is done at the observation station TS7 which is one of the input sources (inlet) to the Jatibarang Reservoir. In the future, Jatibarang Reservoir water will function as a source of clean water for Regional Drinking Water Company Semarang City Semarang City (Hidayah et al, 2016). Based on the analysis of the water quality status of class I river designation, it shows that the condition of the river in TS7 has been lightly polluted.…”

Agricultural waste, especially from the use of fertilizers and pesticides, has become a serious problem in several countries because it has caused a decrease in river water quality. The land use and livelihoods of the people in the Kreo watershed are oriented towards agricultural activities. This study aims to (1) analyze the pattern of agricultural land use in the Kreo watershed and (2) analyze the impact of agricultural waste on river water quality in the Kreo watershed. The method used is descriptive quantitative. Analysis of the impact of agricultural waste on river water quality was carried out by laboratory testing of river water samples that referred to the criteria for water quality standards based on class according to Government Regulation of the Republic of Indonesia Number 82 of 2001 for class I river designation. Laboratory tests of water samples used parameters TSS, TDS, Nitrate, BOD, and COD. While the analysis of the status of water quality using the STORET method. The results showed that the pattern of use of rice fields was clustered upstream and in the middle, farmland was clustered in the downstream and mixed gardens were spread out in the upstream, middle, and downstream areas. The status of river water quality in the upstream and middle parts of the Kreo watershed has been lightly polluted, while the downstream still meets the quality standards. The river water will be harmful to human health if it is intended as a raw source of drinking water.

“…In addition, for the long-term plan the use of Jatibarang Reservoir water in the Kreo Watershed will be used as a source of clean water for Regional Drinking Water Company Semarang City (Hidayah et al, 2016). Therefore, studies related to monitoring the quality of river water in the Kreo watershed are very important to do.…”

“…Konsentrasi karbondioksida sangat erat pula hubungannya dengan konsentrasi oksigen terlarut dalam suatu perairan. Tingginya karbondioksida dalam perairan akan menyebabkan oksigen terlarut dalam perairan menjadi menurun sehingga akan menyebabkan kematian pada ikan,dan pH yang baik untuk peraiaran adalah standard pada kisaran nilai pH 7-8, kesalahan dari ketidakaturan pengukuran pH akan meningkat dengan meningkatnya nilai alkalinitas total [12] Pada penelitian ini didapatkan hasil kadar karbondioksida dalam mg/l. Untuk titik yang pertama yaitu didapatkan 50 mg/l.…”

“…Meskipun peranan CO 2 sangat besar bagi kehidupan organisme air, namun kandungan CO 2 bebas yang berlebihan sangat mengganggu, bahkan merupakan racun langsung bagi ikan. Daya toleransi ikan terhadap kandungan CO 2 bebas dalam air bermacam-macam tergantung jenisnya, tetapi pada umumnya bila lebih dari 15 mg/l dapat memberikan pengaruh yang merugikan bagi ikan [12] Perairan air tawar alami hampir tidak pernah memiliki pH > 9 sehingga tidak ditemukan karbon dalam bentuk karbonat. Pada air tanah, kadar karbondioksida biasanya sekitar 10 mg/l karena sifat air tanah cenderung alkalis.…”

Telah dilakukan penelitian tentang analisis kadar CO2 pada sungai Ampenan di Kota Mataram, Lombok, Indonesia. Tujuan dari penelitian ini untuk mengetahui kadar karbondioksida dalam air sungai. Penelitian ini dilakukan dengan mengambil sampel air pada 5 titik sampel pada sungai Ampenan dan satu kontrol yang diambil dari air yang secara fisik tidak mengalami pencemaran. Hasil pengamatan yang dilakukan secara fisik, sungai Ampenan mengalami pencemaran dari segi bau, warna dan suhu. Berdasarkan hasil analisis kadar CO2 diperoleh hasil pada kelima titik sampel adalah 50, 30, 15 dan 10 mg/l. Kadar CO2 pada sungai Ampenan berada dalam kategori tinggi di atas ambang batas 5-10 mg/l. Kadar karbondioksida pada sungai Ampenan tergolong tinggi karena masyarakat sekitar membuang sampah langsung ke sungai. Solusi untuk mengatasi tingginya karbondioksida adalah melakukan aerasi atau melakukan pengaturan sirkulasi air. Sirkulasi air bisa berjalan dengan baik dengan cara mengurangi sampah disekitar daerah aliran sungai Ampenan, dan diberikan sanksi tegas pada masyarakat yang membuang sampah/limbah ke aliran sungai.

Tilapia (Oreochromis niloticus) is an invasive fish species in Indonesia. A study on biological aspects is expected to be used as an assessment to implement fisheries mitigation, restoration, and enhancement. This study aimed to analyze the environmental conditions, biological aspects of the sex ratio, total length-weight relationship, maturity stages, and tilapia fecundity in the Jatibarang Reservoir. Fish samples were collected four times in July-October 2020 using gill nets (mesh size of 3 inches). The sampling sites were 2 stations located in Jatibarang Reservoir. Environmental parameters were measured, including water temperature, pH, and dissolved oxygen. Fish were measured for total length, weighed for gonads, and total weight. Water temperature, pH, and dissolved oxygen ranged from 28.0-31.9 oC, 6.41-6.70, and 6.04-7.39 mg/l, respectively. The sex ratio of tilapia was 1:1.9 (females: males). Total length ranged from 95 to 349 mm, and total weight ranged from 13 to 798 g. The growth pattern of tilapia was positive allometric. The condition factor of male and female fish was 0.94-1.16 and 0.95-1.21, respectively. 36.8% of the female fishes were ripe stage (IV), and 65.8% of the male fishes were immature stage (I). The fecundity ranged from 28 to 7,852 eggs.
