Penelitian ini bertujuan untuk mengkaji nilai evaporasipotensial (Etc) tanaman kelapa sawit dan tanaman hutan konversi dengan menggunakan model perubahan neraca air menurut Mather (1957) dan Blaney-Criddle pada perkebunan kelapa sawit dengan lahan hutan konversi. Lokasi penelitian terletak di PTPN IX Danau Salak, Kecamatan Astambul Kabupaten Banjar. Hasil penelitian menunjukkan bahwa nilai curah hujan peluang kejadian terlampaui 75% selama 10 tahun terlihat bahwa curah hujan tertinggi diperoleh pada bulan Januari sebesar 249,6 mm/bulan, sedangkan curah hujan terendah diperoleh pada bulan September yaitu sebesar 66,5 mm/bulan. Nilai evapotranspirasi potensial (ETc) rata-rata di lahan kebun sawit adalah 129,96 mm, sedangkan evapotranspirasi aktual (ETA) adalah sebesar 174,23 mm. Nilai kandungan air tanah (KAT) rata-rata sebesar 66,68 mm dengan surplus air sebesar 14,06 mm. Nilai evapotranspirasi potensial (ETc) rata-rata di lahan hutan konversi (karet) sebesar 122,97 mm, sedangkan evapotranspirasi aktual (ETA) sebesar 174,23 mm. Nilai kandungan air tanah (KAT) rata-rata sebesar 66,68 mm, dengan rata-rata surplus air sebesar 21,05 mm. Terdapat perbedaan antara lahan hutan konversi dengan lahan yang sudah dikonversi menjadi perkebunan kelapa sawit. Perubahan ini menyebabkan penurunan nilai surplus air yang ada sekitar 9 mm per tahun dengan perhitungan nilai surplus pada hutan konversi sebesar 1.569 mm per tahun menjadi 1.560 mm per tahun pada lahan perkebunan. Penurunan ini akan berakibat pengurangan pada debit air yang berakibat pengurangan nilai air tersedia yang mampu dimanfaatkan oleh stakeholder pengguna air, dan salah satunya adalah sektor domestik. This study aims to assess the potential evaporation value (Etc) of oil palm and conversion forest plantations using the water balance change model according to Mather (1957) and Blaney-Criddle on oil palm plantations with conversion forest land. The research location is PTPN IX Lake Salak, Astambul District, Banjar Regency. The results showed that the probability of rainfall being exceeded by 75% for 10 years showed that the highest rainfall was obtained in January of 249.6 mm/month, while the lowest rainfall was obtained in September of 66.5 mm/month. The average potential evapotranspiration (ETc) in oil palm plantations is 129.96 mm, while the actual evapotranspiration (ETA) is 174.23 mm. The average value of soil water content (KAT) is 66.68 mm with a surplus of 14.06 mm. The average potential evapotranspiration (ETc) in conversion forest land (rubber) is 122.97 mm, while the actual evapotranspiration (ETA) is 174.23 mm. The average value of soil water content (KAT) is 66.68 mm, with an average surplus of 21.05 mm. There is a difference between conversion forest land and land that has been converted to oil palm plantations. This change causes a decrease in the value of the existing surplus of water by about 9 mm per year with the calculation of the surplus-value in conversion forests from 1,569 mm per year to 1,560 mm per year on plantation land. This decrease will result in a reduction in water discharge which results in a reduction in the value of available water that can be utilized by water user stakeholders, and one of them is the domestic sector.

Sungai Jaing merupakan salah anak Sungai Tabalong yang memiliki manfaat sebagai sumber air baku PDAM bagi masyarakat Kabupaten Tabalong dan habitat untuk budidaya ikan. Di sisi lain, Sungai Jaing juga menerima beban limbah dari berbagai aktifitas rumah tangga, industri dan pertanian/perkebunan. Hasil pantau Dinas Lingkungan Hidup Kabupaten Tabalong tahun 2018 - 2020, terdapat kecenderungan penurunan kualitas air Sungai Jaing yang disinyalemen karena meningkatnya beban pencemaran air. Pengukuran kualitas air dan debit aliran dilakukan pada Februari 2020 dan Oktober 2020 di segmen hulu, tengah, dan hilir badan Sugai Jaing. Hasil perhitungan indeks pencemaran (IP) pada pengukuran Februari 2020 pada ketiga segmen sungai menunjukkan kondisi cemar sedang dengan IP = 5,732 – 7,300 (6,608±0,58). Parameter yang memberi kontribusi besar pada nilai IP adalah DO, Cu, Sulfida, Fenol, Fe, Zn, Detergen dan BOD. Hasil perhitungan IP pada pengukuran Oktober 2020 memperlihatkan seluruh segmen sungai berada pada kondisi cemar ringan dengan IP = 2,694 – 3,378 (3,106 ±0,36). Parameter yang memberi kontribusi besar pada IP adalah Fosfat, BOD, COD, Fe, Cd, detergent, E.Coli dan Coliform. Cu, Fe, dan Zn adalah parameter logam yang memiliki kecenderungan melampaui daya tampung beban pencemaran air. Parameter DO melampaui daya tampung beban pencemaran air di semua lokasi pengukuran dan BOD pada lokasi pengukuran segmen hilir. Parameter BOD dan COD cenderung menunjukkan penurunan DTBPA pada bagian hulu dan hilir, sedangkan parameter DO terdapat kecenderungan penurunan nilai DTBPA pada segmen tengah. Nilai IP dan DBPA lebih buruk pada periode pengukuran Oktober 2020 dibandingkan hasil pengukuran bulan Februari 2020 The Jaing stream is a tributary of the Tabalong River which has benefits as a source for Clean Water Plant of Local Company (PDAM) Tabalong Regency and a habitat for fish farming. On the other hand, the Jaing River also receives a load of waste from the various household, industrial and agricultural/plantation activities. The results of monitoring the DLH Tabalong in 2018 - 2020, there is a tendency to decrease the water quality, which is caused by the increasing load pollution capacity. Measurement of water quality and the flow rate was carried out in February 2020 and October 2020 include the upstream, middle, and downstream segments of the Sugai Jaing watershed. The results of the pollution index (IP) in February 2020 measurements in the three river segments showed moderately polluted conditions with IP = 5.732 – 7,300 (6.608±0.58). The greatly contributed parameters to the IP value were DO, Cu, Sulfide, Phenol, Fe, Zn, Detergent, and BOD. The results of IP calculations in October 2020 show that all river segments are in a lightly polluted condition with IP = 2.694 – 3.378 (3.106 ± 0.36). The greatly contributed parameters to IP were Phosphate, BOD, COD, Fe, Cd, detergent, E.Coli, and Coliform. Cu, Fe, and Zn are metal parameters that have a tendency to exceed the water pollution load capacity. The DO parameter exceeds the water pollution load capacity at all measurement locations and BOD at the downstream segment measurement locations. The BOD and COD parameters tend to show a decrease in pollution load capacity (PLC) in the upstream and downstream sections, while the DO parameter has a tendency to decrease in the middle segment. The IP and PLC values were worse in the October 2020 measurement period than the February 2020 measurement results
