“…Although fishing operations were high so that it can threaten mackerel populations. The environment of sea on the islands of Morotai, Bacan and Ternate that has not been polluted (Marasabessy et al, 2010;Edward, 2015;Najamuddin et al, 2020), provides the opportunity for the presence of mackerel to make it a food area. Scientific approach was carried out such as reducing fishing effort in order to obtain maximum profit, but it still leads to fishing that is already large (Prahadina et al, 2015).…”

High exploration activity is feared to have an impact to mackerel populations. A sustainable management approach should be taken to provide information about the status of mackerel populations. Study of mackerel population status can be carried out through genetic information. The DNA of the fish samples were collected at traditional fish markets (Morotai, Bacan and Ternate). Laboratory works such as extraction, amplification, electrophoresis and DNA sequencing were analysis at the Indonesian Biodiversity Laboratory (Bionesia). The molecular characteristics of Rastrelliger kanagurta were 374 base pairs (bp). The composition of nucleotides showed the similarity of frequencies between species. Phylogenetic relationship of R. kanagurta in North Maluku Sea suggested that there was any differentiation. The genetic diversity of R. kanagurta was high with a total number of haplotypes and diverse nucleotide diversity. The minimum spawning networks (MSN) found 5 haplotype networks from a total of 12 samples. Morphological measurements of standard length, head height, body width, pectoral fin length and tail were found to have variable values. The length of the weight of the fish is obtained of b = 3, indicating that the growth pattern was isometric or weight gain was equivalent to the growth of the fish length.Keywords: Biodiversity, conservation, ecology, morphology, species

“…Salinitas perairan Teluk Manado bervariasi dari waktu ke waktu dan dari lokasi ke lokasi dalam teluk, tergantung pada faktor alam utama yaitu curah hujan dan masukan air dari sungai-sungai yang mengalir ke Teluk Manado. Menurut Mansyur (2008) sebaran salinitas di laut juga dipengaruhi oleh berbagai faktor seperti musim, sirkulasi air, penguapan, curah hujan, dan aliran sungai. Salinitas suatu perairan penting artinya dalam ekologi perairan karena berkaitan dengan parameter fisika kimia perairan dan keberadaan organisme air.…”

The city of Manado is famous for its fishery products, but human activities also cause problems of seawater pollution and a decrease in water quality. This study aims to examine the water quality around Malalayang Beach Walk in Manado City with a focus on physical and chemical parameters. The study was conducted at five stations with three repetitions at high and low tide. The results showed that the water temperature was relatively homogeneous, with a range of 30.02-30.29oC at high tide and 30.39-30.81oC at low tide. Turbidity is in the range of 20.1-22.5 NTU at high tide and 16.0-21.7 NTU at low tide, exceeding the quality standard. DO values conform to quality standards (5.46-8.07 mg/L at high tide and 5.69-6.32 mg/L at low tide), but TDS reaches 23900-28600 mg. L at high tide and 26600-28600 mg/L at low tide, far from the common values of 1500 mg/L. Salinity values range from 25.02-30.29 ppt at high tide and 30.35-30.50 ppt at low tide. Pollution and degradation need to be better controlled and monitored. Keywords: Water quality, Temperature, Turbidity, Dissolved oxygen (DO), Total dissolved solids (TDS), Salinity. Abstrak Kota Manado terkenal dengan hasil perikanannya, namun aktivitas manusia juga menyebabkan masalah pencemaran air laut dan penurunan kualitas perairan. Penelitian ini bertujuan untuk mengkaji kualitas perairan di sekitar Malalayang Beach Walk Kota Manado dengan fokus pada parameter fisika dan kimia. Penelitian dilakukan di lima stasiun dengan tiga kali pengulangan pada saat air pasang dan surut. Hasil penelitian menunjukkan bahwa suhu perairan relatif homogen, dengan rentang nilai 30,02-30,29oC saat pasang dan 30,39-30,81oC saat surut Kekeruhan berada pada rentang 20,1-22,5 NTU saat pasang dan 16,0-21,7 NTU saat surut, melebihi standar baku mutu. Nilai DO sesuai dengan standar baku mutu (5,46-8,07 mg/L saat pasang dan 5,69-6,32 mg/L saat surut), namun TDS mencapai 23900-28600 mg/L saat pasang dan 26600-28600 mg/L saat surut, jauh dari nilai umum 1500 mg/L. Nilai salinitas berkisar antara 25,02-30,29 ppt saat pasang dan 30,35-30,50 ppt saat surut. Pencemaran dan penurunan kualitas perlu dikendalikan dan dipantau secara lebih baik. Kata Kunci: Kualitas air, Suhu, Kekeruhan, Dissolved oxygen (DO), Total dissolved solids

“…According to Najamuddin [62], the condition of Ternate waters has decreased in quality with a lightly polluted status (see Table 2), which is believed to have been caused by an increase in anthropogenic activity as a result of the waterfront city development. It has also been shown that there was an increase in the level of pollution in Ternate waters, specifically nitrate, which experienced a significant increase that exceeded the quality standard (0.008 mg/l).…”

Indonesians had lived a lifestyle in the past that was very harmonious with their environment. Almost all tribes and communities had policies for preserving and managing their surroundings based on local wisdom that was passed down from previous generations. However, due to the increase in the development of modern cities, this knowledge began to erode. Therefore, this study aims to analyze the impact of waterfront city development on coastal resources and local wisdom in relation to the preservation of sustainable environments in the archipelago city of Ternate. This study was performed through a literature review, field observations, and interviews with 250 respondents. The results show that the increase in waterfront development activities can reduce the potential of coastal resources as well as have an impact on changes in regional characteristics and features of local wisdom in coastal areas due to reclamation. The conservation of environmental resources and the management of coastal areas based on local wisdom and sustainable development can improve the value of the environment and reduce the pressure on coastal resources. The findings of this study can improve insight into the importance of sustainable waterfront development based on local wisdom, specifically in archipelagic cities.
