Sea cucumbers are an essential fishery resource. Therefore, effective aquaculture methods should be developed to achieve their optimal production. Sea cucumbers are susceptible to various environmental factors, one of which is water quality. Monitoring water quality based on physical and chemical parameters should be useful to the rearing system in aquaculture. In practical use, farmers usually monitor only temperature, salinity, and pH, neglecting the essential role of chemical parameters. This review focuses on and urges the monitoring of physical and chemical parameters. We explored the water quality parameters that may be crucial to the sea cucumber rearing system, including temperature, salinity, pH, dissolved oxygen, ammonia, turbidity, particulate organic matter, total nitrogen, nitrate, nitrite, ammonium, silicate, and phosphate. Furthermore, this paper presents a practical way to monitor the aquaculture or rearing system of sea cucumbers. It is suggested that temperature and salinity are the crucial physical parameters, while the essential chemical parameters are phosphate, nitrate, and ammonia.

Siak River is one of the biggest rivers and the deepest in Riau Province in Indonesia with its 20-30 depth and depth 370 kilometers. The Siak River used for bathing, washing, dumping industrial palm oil, plantation, domestic waste, and port so it has an impact on water quality changing. This study analyzed the water quality and distribution spatial physical and chemical parameters the river around in Pekanbaru city, using Principal Component Analysis (PCA), this study used laboratory in situ and ex situ water quality measurement instruments. Water sampling each station done three times in two weeks during October to November 2019. The results obtained from this study shows the water quality of these 6 stations in the category of bad and the water quality from headwaters to downstream river influenced by organic parameter as a dominant pollutant. The correlation of water quality characteristic was 74.4% main factor 1 (F1) 47.4% and main factor 2 (F2) 26.7% with main characteristics fecal coliform, phosphate, and nitrate. Grouping these characteristics through a dendrogram showed three levels of relationship based on the characteristic parameter. The first group stands for station 1,2, and 4 have higher brightness and Dissolved oxygen (DO) parameters than other stations. The second group stands for stations 3 and 5 that have relatively high in parameter phosphate and nitrate. The third group is station 6 (river estuary) which results in shows high of fecal coliform proportional to pollution. The study can be concluded that three groups heavily contaminated. Each group has different parameters that show influence upland and waters activities.Keywords: Distribution of spatial, The quality of water, Siak River, Physical and Chemical Parameters, PCA ABSTRAKSungai Siak merupakan salah satu sungai terbesar di Provinsi Riau dan terdalam di Indonesia, dengan kedalaman sekitar 20-30 meter dan panjang 300 kilometer. Sungai siak masih dimanfaatkan oleh masyarakat sebagai sarana Mandi Cuci Kakus (MCK), tempat buangan limbah industri kelapa sawit, perkebunan, rumah tangga dan pelabuhan, sehingga berdampak pada perubahan kualitas perairan. Penelitian dilakukan untuk menganalisa kualitas dan distribusi spasial karateristik fisik-kimia perairan Sungai Siak di sekitar Kota Pekanbaru, dengan menggunakan Principal Component Analysis (PCA). Kajian menggunakan instrument pengukuran kualitas air in situ dan ex situ di laboratorium. Pengambilan sampel air pada masing-masing stasiun dilakukan sebanyak tiga kali setiap dua minggu selama bulan Oktober hingga November 2019. Hasil yang diperoleh dari kajian ini adalah kualitas air di keenam stasiun masuk dalam katagori buruk dan mengalami penurunan kualitas dari hulu ke hilir yang disebabkan bahan organik. Korelasi karakteristik kualitas air sebesar 74,3%, faktor utama 1 (F1)  47,4% dan faktor utama 2 (F2) 26,7% dengan penciri utama fecal coliform, fosfat dan nitrat. Pengelompokan stasiun pada dendogram klarifikasi hierarki menunjukkan adanya tiga tingkat hubungan kekerabatan berdasarkan parameter pencirinya. Kelompok satu terdiri dari stasiun 1, 2 dan 4 memiliki hasil relatif tinggi pada parameter kecerahan dan oksigen terlarut (DO) dibandingkan dengan stasiun lainnya. Kelompok dua terdiri dari stasiun 3 dan 5 memiliki hasil relatif tinggi pada paramter nitrat dan fosfat dibandingkan dengan stasiun lainnya. Kelompok tiga adalah stasiun 6 (muara sungai sail) dengan parameter fecal coliform relatif tinggi yang berbanding lurus dengan tingkat pencemarannya. Berdasarkan hasil kajian dapat disimpulkan bahwa tiga kelompok sama-sama tercemar berat, namun masing-masing kelompok memiliki perbedaan parameter pencirinya yang memperlihatkan pengaruh berbagai aktifitas di darat maupun di perairan itu sendiri.Kata kunci: Distribusi spasial, Kualitas air, Sungai Siak, Parameter fisika dan kimia, PCA

This service aims to provide information about the value of good water quality and demonstrate directly the tools used to measure it which aim to cultivate Batak fish based on biological, physical and chemical parameters such as temperature, dissolved oxygen, carbon dioxide, pH, and provide information on the names of measuring devices. . This service has been carried out in Gorat Village, Toba Samosir Regency with the method of counseling and material discussion (exposure and question and answer), as well as the practice of measuring water quality externally and analyzing the results of its value. The results of the counseling show that many fish farmers do not understand the value of good water quality for batak fish cultivation and not many know the equipment that can be used to check water quality. From this counseling, it can be seen that the interest of fish farmers and the community is very high, and they become more aware of the value of good water quality for fish farming and know the equipment. Abstrak Pengabdian ini bertujuan untuk memberikan penyuluhan tentang nilai kualitas air yang baik dan mendemonstrasikan langsung alat yang digunakan mengukurnya yang bertujuan untuk membudidayakan ikan batak berdasarkan parameter biologi, fisika dan kimia seperti suhu, oksigen terlarut, karbondioksida, pH, serta memberikan informasi nama alat-alat pengukurnya. Pengabdian ini telah dilakukan di Desa Gorat, Kabupaten Toba Samosir dengan metode penyuluhan dan diskusi materi (paparan dan tanya jawab), serta praktek pengukuran kualitas air secara eksitu dan menganalisis hasil nilainya. Hasil penyuluhan menunjukan bahwa banyaknya petani ikan yang belum paham tentang nilai kualitas air yang baik untuk budidaya ikan batak serta belum banyak yang mengetahui peralatan yang dapat digunakan untuk memeriksa kualitas air. Dari penyuluhan ini terlihat animo petani ikan dan masyarakat sangat tinggi, dan mereka menjadi lebih paham tentang nilai kualitas air yang baik untuk budidaya ikan serta mengetahui peralatannya.
