Dua muara utama lokasi kemunculan ikan nike di Perairan Gorontalo adalah Muara Bone dan Muara Paguyaman yang secara administratif masing-masing terletak di Kota Gorontalo dan Kabupaten Boalemo, Provinsi Gorontalo. Tujuan penelitian ini adalah membandingkan karakter morfometrik serta menentukan sebaran frekuensi panjang, pola pertumbuhan, dan faktor kondisi ikan nike yang ditemukan di Muara Bone dan Muara Paguyaman. Total sampel secara random sebanyak 700 hingga 2275 ekor dikumpulkan dari perairan dengan menggunakan tagahu dalam dua musim penangkapan, yaitu Juli dan September 2021. Sampel diawetkan dengan menggunakan es batu dan segera dilakukan pengukuran panjang total, panjang standar, tinggi badan, lebar badan, diameter mata, diameter kepala, dan bobot tubuh. Hasil penelitian selama dua musim penangkapan menunjukkan bahwa ukuran morfometrik ikan nike di Muara Paguyaman relatif lebih besar dibandingkan dengan nike yang ditemukan di Muara Bone. Sebaran frekuensi panjang nike per hari kemunculan mengindikasikan schooling nike yang ditemukan pada setiap musim penangkapan tersusun dari populasi multi kohort. Pola pertumbuhan nike selama penelitian adalah alometrik positif dan alometrik negatif. Adapun kisaran nilai faktor kondisi rata-rata ikan nike di Muara Bone dan Paguyaman masing-masing adalah 0,970-1,044 dan 0,888-1,431.The two main water areas in Gorontalo for the emergence of nike fish are Bone and Paguyaman Estuaries. Each ecosystem is administratively located separated in Gorontalo City and Boalemo Regency, Gorontalo Province. The research aimed to compare the morphometric characters and to determine the distribution of length frequencies, growth patterns, and condition factors of the nike found in those estuaries. A total random sample of 700 to 2275 individuals were caught from the waters using tagahu during fishing seasons, July and September 2021. The samples were preserved using ice cubes and immediately measured for total length, standard length, body height, body width, eye diameter, head diameter, and body weight. The data showed that the morphometric size of the nike in the Paguyaman Estuary was relatively larger compared to those found in the Bone Estuary. The length frequency distribution per day of nike appearance indicates that schooling from each season was composed of a multi-cohort population. Nike's growth pattern during the study was positive allometric and negative allometric. The range of condition factor values for the average nike fish in Muara Bone and Paguyaman were 0.97 – 1.044 and 0.888 – 1.431, respectively.

Activities around Bone River, one of the largest rivers in Gorontalo Province, include agriculture, settlement, gold mining, sand excavation, industry, and illegal logging. This research aimed to report the water quality status of Bone River using the STORET method as an index commonly used for measuring pollution levels in a water body, which the Indonesian government regulates, as stated in the Decree of the Minister of Environment, No. 115, 2003. This work involved data from 2021-2023 along the upstream to downstream of the river. There were 12 water quality parameters measured: temperature, TSS, DO, pH, COD, BOD, nitrate, phosphate, ammonia, and the heavy metals (Pb, Cd, and Hg) concentration. This study revealed that parameters met water quality standards for class I and class II: temperature, pH, DO, Pb, and Cd. The index scores ranged from -96 to 0. The upstream area was categorized as good, and the midstream to downstream was recognized as heavily polluted. This pollution level is dominated by organic waste from agricultural and domestic household activities. The concentration value consistently exceeds the quality standard in all data from St 5 to St 12. These two parameters are enough to significantly cause worsening water quality based on the STORET with a total score contribution of -40. BOD and COD parameters contribute the most to the river pollution level.Keywords:Water qualityPollutionSTORETBone River

Latar belakang: Sungai merupakan ekosistem perairan yang penting dalam siklus hidrologi, berfungsi sebagai daerah resapan air bagi lingkungannya. Habitat fisik dan kondisi kesehatan perairan sungai sangat dipengaruhi aktivitas antropogenik serta karakteristik lingkungan sekitar. Sungai Bone yang menjadi pusat aktivitas masyarakat di Gorontalo sangat rentan terhadap pencemaran. Makroinvertebrata potensial dijadikan sebagai alat pemantauan pencemaran di sungai karena karakteristik komunitas penyusunnya, yang ditandai dengan perilaku menetap, mobilitas terbatas, dan sensitif terhadap kondisi perairan. Penelitian ini bertujuan untuk menilai kualitas perairan Sungai Bone berdasarkan kondisi habitat fisik dan keanekaragaman makroinvertebrata.Metode: Penilaian terhadap kondisi habitat fisik dan kualitas perairan dilakukan pada 12 stasiun pengamatan yang mewakili aliran utama hulu-hilir Sungai Bone. Penentuan kondisi habitat fisik sungai didasarkan pada pemeriksaan dan penilaian terhadap kriteria tingkat kesehatan habitat sungai dimana parameter yang diamati berupa indikator karakteristik substrat dasar, indikator faktor gangguan, parameter fisika-kimia air. Struktur komunitas makroinvertebrata dianalisis melalui perhitungan keragaman famili makrozoobentos secara keseluruhan, persentase kelimpahan EPT, nilai indeks keanekaragaman (H’), dominasi (D’) serta keseragaman (E’). Penentuan kualitas perairan dilakukan berdasarkan pendekatan Biotilik.Hasil: Hasil penelitian ini mengungkapkan variasi spasial dalam komunitas makroinvertebrata, parameter kualitas air (terutama BOD, COD). Semakin ke hilir kondisi habitat fisik, dan kualitas perairan Sungai Bone cenderung mengalami penurunan.Simpulan: Kualitas perairan Sungai Bone berdasarkan hasil penelitian terbagi menjadi tiga kategori kelompok tercemar yaitu tidak tercemar-sehat (bagian hulu), tercemar ringan-kurang sehat (bagian tengah), dan tercemar ringan-tidak sehat (bagian hilir). Kondisi tercemar di Sungai Bone, terutama di bagian tengah hingga hilir, kemungkinan besar disebabkan oleh pencemaran yang berasal dari aktivitas antropogenik masyarakat. ABSTRACT Title: Physical Habitat Conditions and Macroinvertebrate Diversity as Indicators of Pollution in the Bone River, GorontaloBackground: Rivers are water ecosystems that are important in the hydrological cycle, functioning as water catchment areas for the environment. Anthropogenic activities and the characteristics of the surrounding environment greatly influence the physical habitat and health conditions of river waters. The Bone River, which is the center of community activity in Gorontalo, is very vulnerable to pollution. Macroinvertebrates have the potential to be used as a tool for monitoring pollution in rivers because of the characteristics of their constituent communities, which are characterized by sedentary behavior, limited mobility, and sensitivity to water conditions. This research aims to assess the water quality of the Bone River based on physical habitat conditions and macroinvertebrate diversity.Method: Assessment of physical habitat conditions and water quality was carried out at 12 observation stations representing the main upstream and downstream streams of the Bone River. The evaluation of the river's physical habitat condition was based on the examination and assessment of criteria related to river habitat health, with observed parameters including substrate characteristics, disturbance indicators, and physicochemical water parameters. The structure of the macroinvertebrate community was analyzed by calculating the overall diversity of macrozoobenthos families, the percentage of EPT (Ephemeroptera, Plecoptera, Trichoptera) abundance, and indices of diversity (H’), dominance (D’), and evenness (E’). The water quality assessment was conducted using the Biotilik approach.Result: The results of this study revealed spatial variations in macroinvertebrate communities, water quality parameters (especially BOD, COD). The further downstream the physical habitat conditions, the water quality of the Bone River tends to decline.Conclusion: Based on research results, the water quality of the Bone River is divided into three categories of polluted groups: not polluted-healthy (upstream part), lightly polluted-unhealthy (middle part), and lightly polluted-unhealthy (downstream part). The polluted conditions in the Bone River, especially in the middle to downstream parts, are most likely caused by pollution originating from the community's anthropogenic activities.

The Bone River faces potential pollution due to human activities around it. To ensure this, macrozoobentos are used as bioindicators by utilizing the characteristics of their constituent communities that exhibit sedentary behavior, limited mobility, and sensitivity to aquatic conditions. This study aims to examine the abundance and diversity of macrozoobentos in the Bone River and Bolango River, Gorontalo Province. The research was conducted from May to August 2023 at several observation stations on both rivers. The identification results showed a total of 127 macrozoobentos individuals consisting of 72 individuals in the Bone River and 55 individuals in the Bolango River, with the dominance of the Baetidae (PlatyBaetis) and Hydropsychidae (Cheumatopsyche and Hydropsyche) families that are widespread in both locations. A low dominance index indicates the absence of a single species that dominates significantly, while the fairly diverse distribution of taxa reflects relatively good water quality conditions in both rivers. These findings serve as an important basis for the sustainable monitoring and management of aquatic resources in the region.

Judul : Level Kualitas Perairan Bagian Hilir Sungai Paguyaman, Gorontalo, Indonesia: Suatu Kajian Berdasarkan Distribusi Mikroalga dan Indeks SaprobikLatar Belakang: Sungai Paguyaman membentang sepanjang 136,25 km dan merupakan daerah aliran sungai terbesar kedua di Provinsi Gorontalo. Bagian hilir sungai ini bermuara di Teluk Tomini dan berada di perbatasan antara Desa Girisa Kecamatan Paguyaman Kabupaten Boalemo dan Desa Bilato Kecamatan Boliyohuto Kabupaten Gorontalo. Bagian hilir sungai ini menjadi sumber penghidupan bagi masyarakat di sekitarnya, namun kualitas perairannya terancam akibat pencemaran organik yang berasal dari aktivitas domestik dan pertanian. Tujuan dari penelitian ini adalah untuk mengidentifikasi jenis dan distribusi mikroalga, dan menilai kualitas perairan menggunakan indeks saprobik di wilayah hilir Sungai Paguyaman, Gorontalo.Metode: Pengambilan sampel dilakukan pada empat stasiun dengan masing-masing tiga ulangan, dimulai dari stasiun 1 tepat di bibir muara sungai, kemudian disusul stasiun 2 hingga 4 dengan jarak antar stasiun 3-4 km. Mikroalga yang diamati mencakup mikroalga planktonik (fitoplankton) dan mikroalga yang melekat pada substrat batu (perifiton). Sementara parameter fisik perairan mencakup kedalaman air, suhu, kecepatan arus, kecerahan, dan substrat dasar, serta parameter kimia perairan mencakup pH, oksigen terlarut (DO), dan salinitas.Hasil: Hasil penelitian menunjukkan bahwa mikroalga yang ditemukan di wilayah hilir Sungai Paguyaman berasal dari 10 kelas yang terdiri dari 101 spesies dan 45 genus. Komposisi terbanyak berasal dari kelas Bacillariophyceae.Simpulan: Berdasarkan nilai indeks keanekaragaman (H'), indeks dominansi dan indeks keseragaman mikroalga, perairan secara umum berada dalam kategori komunitas stabil dengan keberadaan atau kepadatan biota yang merata. Nilai indeks saprobik (SI) 1,64 dan nilai indeks keadaan trofik (TSI) 0,65 menunjukkan bahwa tingkat saprobitas wilayah hilir Sungai Paguyaman saat ini berada pada tingkat Oligo/b-mesosaprobik yaitu termasuk pada kategori tercemar ringan. Temuan ini mengindikasikan bahwa perairan di hilir sungai mengalami penurunan kualitas yang dapat berdampak pada kesehatan ekosistem dan masyarakat. ABSTRACT Background: Paguyaman River stretches for 136.25 km and represents the second largest drainage basin in Gorontalo Province. Its downstream area of the river empties into Tomini Bay and is located on the border between Girisa Village, Paguyaman Subdistrict, Boalemo Regency, and Bilato Village, Boliyohuto Subdistrict, Gorontalo Regency. This regions constitutes a vital source of livelihood for the local community. However, organic pollution from domestic and agricultural activities threatens the quality of its waters. The objective of this study is to identify the types and distribution of microalgae and assess water quality using saprobic index in the downstream area of Paguyaman River, Gorontalo.Method: Sampling was conducted at four stations with three replications per station. The sampling began at station 1, located at the river mouth, and continued to stations 2 through 4, with a distance of 3-4 km between stations. Microalgae observed included planktonic microalgae (phytoplankton) and microalgae attached to rock substrates (periphyton). The physical parameters included water depth, temperature, current velocity, brightness, and bottom substrate, while the chemical parameters included pH, dissolved oxygen (DO), and salinity.Result: The findings revealed that microalgae in the downstream area of the Paguyaman River came from 10 classes of 101 species and 45 genera. The most significant composition comes from the Bacillariophyceae class. Conclusion: According to the diversity index (H'), dominance index, and uniformity index of microalgae, the waters are generally classified as stable communities, characterized by the presence or density of biota that are evenly distributed. The Saprobic Index (SI) value of 1.64 and the Trophic Status Index (TSI) value of 0.65 indicate that the saprobity level of the downstream area of the Paguyaman River is currently at the Oligo/b-mesosaprobic level, which is included in the lightly polluted category. This finding indicates that the river downstream is experiencing degrading, potentially affecting the health of the ecosystem and the surround community.
