Selar termasuk komoditas ikan laut yang bernilai ekonomis karena permintaan pasar yang tinggi dan didukung oleh ketersediaan populasi di alam sepanjang tahun. Truss morfometrik ikan merupakan salah satu karakter terukur yang umum diterapkan dalam studi morfologi ikan sebagai potensi pembeda seksual ikan pada spesies tertentu. Tujuan penelitian ini adalah menyajikan informasi mengenai morfologi, menentukan rasio truss morfometrik terhadap panjang tubuh total yang dapat dijadikan karakter pembeda seksual, serta membandingkan pola pertumbuhan Selar crumenophthalmus jantan dan betina. Jumlah sampel sebanyak 100 ekor dikumpulkan secara random di Tempat Pendaratan Ikan Tenda Kota Gorontalo selama dua hari penangkapan pada bulan Juni 2022. Hasil pengamatan morfologi menunjukkan bahwa bentuk tubuh S. crumenophthalmus adalah kompres dengan tipe sisik sikloid. Bagian dorsal tubuh berwarna biru gelap kehijauan, bagian ventral berwarna silver cenderung putih, terdapat area tipis berwarna kuning membujur dari batas operkulum sampai batang ekor pada sisi lateral tubuh yang terletak di atas linea lateralis, sirip kaudal berbentuk cagak dan simetris, memiliki rumus sirip DIX, 24-27 dan AIII, 21-23. Terdapat 14 truss morfometrik yang dapat dijadikan sebagai ciri pembeda S. crumenopthalmus jantan dan betina yaitu 1 karakter pada bagian kepala (A4), 6 karakter pada tubuh bagian anterior (B1, B2, B4, B5, B6, B9), 3 karakter pada tubuh bagian posterior (C2, C5, C6), dan 4 karakter pada bagian ekor (D1, D2, D3, D5). Adapun pola pertumbuhan spesies jantan dan betina pada sampel riset ini sama-sama bersifat allometrik positif. Selar is a marine fish commodity that has economic value due to high market demand and is supported by the availability of natural populations throughout the year. Fish morphometric truss is one of the measurable characteristics that is commonly applied in the study of fish morphology as a potential sexual differentiation of fish in certain species. The aim of this research is to present information regarding morphology, determine the ratio of morphometric truss to total body length which can be used as a sexual distinguishing character, and compare the growth patterns of male and female Selar crumenophthalmus. A total of 100 samples were collected randomly at the Gorontalo City Tent Fish Landing Site during two days of fishing in June 2022. The results of morphological observations showed that the body shape of S. crumenophthalmus was compressed with cycloid scale type. The dorsal part of the body is dark greenish blue, the ventral part is silver, and tends to be white, and there is a thin yellow area stretching from the border of the operculum to the caudal peduncle on the lateral side of the body which is located above the linea lateralis, the caudal fin is forked and symmetrical, has the fin formula DIX, 24-27 and AIII, 21-23. There are 14 morphometric trusses that can be used as distinguishing characteristics of male and female S. crumenopthalmus, namely 1 character on the head (A4), 6 characters on the anterior body (B1, B2, B4, B5, B6, B9), 3 characters on the body the posterior (C2, C5, C6), and 4 characters in the tail (D1, D2, D3, D5). The growth patterns of male and female species in this research sample were both positive allometric.

This study presents a comprehensive checklist of sea cucumber species found in Biluhu Timur waters, Tomini Bay, Gorontalo, Indonesia, across the new moon and full moon lunar phases. The survey identified eight species across five genera, including Actinopyga miliaris, A. mauritiana, Holothuria scabra, and H. leucospilota, noting significant distribution patterns influenced by lunar cycles and different biomes at three stations. Actinopyga miliaris and A. mauritiana, both classified as Vulnerable, were more active in the seagrass biome of Station I during the full moon. H. leucospilota, classified as Least Concern, was highly prevalent in the sandy substrate biome of Station II during the new moon, indicating a strong ecological association with that habitat. Stichopus horrens, classified as Data Deficient, showed notable activity in the coral reef biome of Station III. Environmental parameters such as water temperature, salinity, and pH were measured at each station to understand the conditions influencing these species. This study highlights the importance of lunar phases, biomes, and environmental variables on sea cucumber distribution. The findings underscore the need for conservation efforts that consider these factors to protect species vulnerable to overfishing and habitat degradation. Further research should include genetic analysis and expanded temporal and spatial scales to develop effective conservation strategies and sustainable management practices

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.
