Abstract

Penyu merupakan reptil berpunggung keras, hidup di air laut dan berkembang biak secara bertelur. Penyu tergolong hewan yang dilindungi dengan kategori Appendix I CITES (Convention on International Trade in Endangered Species), sehingga segala bentuk pemanfaatan dan peredarannya harus mendapat perhatian secara serius. Lokasi peneluran penyu merupakan daerah pantai berpasir yang luas dan landai dan terletak di pantai bagian atas. lokasi peneluran penyu di Kabupaten Halmahera Utara diantaramya adalah Pulau Meti dan Pulau Pasir Timbul. Penelitian ini bertujuan mengetahui pengaruh struktur pasir dan rona lingkungan terhadap penentuan lokasi peneluran penyu. Penelitian menggunakan metode purposive dilakukan secara sengaja berdasarkan informasi yang diperoleh dari masyarakat. Data apendik menyangkut struktur pasir, suhu, kadar air liang peneluran serta dokumentasi vegetasi dilakukan secara langsung di lapangan. Hasil analisa substrat liang peneluran pada Pulau Meti pada lokasi LP1 didominasi dengan kategori butiran 0.425-1 mm sebanyak 33.45%, 0.25-0.425 mm sebanyak 27.09% dan 0.125-0.25 mm sebanyak 24.62%. Lokasi LP2 didominasi dengan kategori butiran 0.425-1 mm sebanyak 31.47%, 0.25-0.425 mm sebanyak 28.46% dan 0.125-0.25 mm sebanyak 20.07%. Lokasi LP3 didominasi dengan kategori butiran 0.425-1mm sebanyak 34.41% dan 0.25-0.425 mm sebanyak 31.95%. kisaran suhu liang peneluran LP1 berkisar antara 29.2-31.2°C, LP2 berkisar antara 29.9-31.9°C dan LP3 berkisar antara 30.4-32.1°C. Kadar air sarang liang peneluran LP1 berkisar antara 8.4-10.3°C, LP2 berkisar antara 8.2-9.7°C dan LP3 berkisar antara 6.5-8.9.Vegetasi laut lokasi peneluran terdiri atas Enhalus acoroides dan Sargasum arnaudianum yang merupakan habitat yang cocok untuk daerah pembesaran tukik. Kemiringan pantai lokasi peneluran LP1 dan LP2 memiliki kemiringan 35°, sedangkan LP3 memiliki kemiringan pantai bervariasi 350-450 dan bahkan ada bagian pulau LP3 memiliki kemiringan mencapai 900 diakibatkan oleh abrasi sehingga menjadi barrier bagi penyu mencapai lokasi peneluran. Vegetasi darat lokasi LP1 dan LP2 didominasi oleh tumbuhan besar berbentuk pohon sedangkan lokasi LP3 didominasi oleh tumbuhan perdu dan merayap.

Abstract

Lingkungan perairan mempengaruhi tipe pertumbuhan (Lifeform) karang. Untuk mengetahui jenis dan tipe pertumbuhan karang di perairan Pulau Meti Kecamatan Tobelo Timur Kabupaten Halmahera Utara, penelitian ini dilakukan pada bulan April ? Juni 2016 dengan menggunakan metode Line Intercept Transec (LIT) dan metode Photo Line Intercept Transec (PLIT). Hasil pengamatan menunjukkan bahwa tipe pertumbuhan karang yang ditemukan di perairan Pulau Meti sebagian besar didominasi oleh karang dengan tipe pertumbuhan non acropora sebanyak 8 tipe pertumbuhan dan 5 tipe pertumbuhan karang acropora. Kondisi ini disebabkan karena perairan Pulau Meti merupakan tipe perairan terbuka dengan kecepatan arus dan gelombang yang cukup tinggi serta fluktuasi perubahan kualitas air yang terjadi dengan cepat.

Abstract

Tiga dari enam jenis penyu di Indonesia yaitu; Penyu Hijau (Chelonia mydas), Penyu Sisik (Eretmochelys imbricata) dan Penyu Abu-abu (Lepidocheys olivacea) dapat ditemukan di Pulau Meti. Ketiga jenis penyu ini dapat ditemukan pada 2 lokasi yang berbeda di pulau ini pada akhir bulan Maret hingga Juni setiap tahun. Penelitian ini bertujuan untuk mengetahui persepsi masyarakat Pulau Meti terhadap larangan dan pelestarian penyu. Penelitian dilakukan selama bulan Juni 2019 di Pulau Meti sebagai lokasi peneluran dan penetasan penyu. Penelitian ini menggunakan metode survey dengan pemilihan responden untuk wawancara dilakukan secara purposif (Purposive Sampling) yang difokuskan pada kelompok nelayan. Jumlah responden sebanyak 30 orang, data yang diperoleh diolah dengan menggunakan metode deskriptif kualitatif. Hasil penelitian menunjukkan bahwa 42.15% responden mengetahui tentang larangan penangkapan penyu dan pengambilan telur penyu oleh pemerintah, namun masih dilakukan secara sembunyi-sembunyi. 31.40% dari responden mengaku tidak peduli dengan larangan pemerintah.  15.7% responden tidak tahu tentang larangan eksploitasi penyu, 8.26% responden pernah dengar tentang larangan eksploitasi penyu, 2.48% responden baru tahu tentang larangan eksploitasi penyu menunjukkan masih kurangnya sosialisasi tentang larangan ini kepada masyarakat. 55.71% responden sangat setuju dan 2.86% setuju pelestarian penyu perlu lebih diperhatikan, 11.9% responden tidak setuju untuk dilakukan pelestarian penyu sedangkan 21.9% responden tidak peduli tentang pelestarian penyu. Sikap masyarakat “asal tidak ada yang tahu”, “asal tidak ada yang lapor”, “asal petugas tidak tahu” harus diubah. karena itu, kegiatan sosialisasi dan monitoring serta penerapan sanksi perlu dilakukan bagi yang melanggar peraturan.

Abstract

The Aim of this research was to describe the profile of freshwater aquaculture, identify external and internal factors and formulate a strategy for developing freshwater aquaculture. The research was conducted at freshwater aquaculture locations in West Kao and Tobelo. The method used purposive sampling methods, observation, and interviews, data analysis used qualitative descriptive methods and SWOT. The results showed that human resources and skills in cultivating fish, availability of land, water sources and locations, the existence of Balai Benih Ikan Lokal are strength factors, while capital and experience, quality and quantity of seeds are weaknesses that affect the development of freshwater aquaculture. On the other hand, threats such as the lack of government guidance and assistance, weather, location security are obstacles in taking advantage of opportunities consisting of opening employment opportunities, developing cultivation technology including Minapadi, selling prices, and marketing. The strategies used to formulate the development of freshwater aquaculture in West Kao and Tobelo are increasing the role of the government through outreach activities, increasing the quality and quantity of fish cultured by BBIL, developing an integrated aquaculture system, improving the safety system of aquaculture sites and increasing knowledge about hatchery techniques to cultivators.

Abstract

Human activities in coastal waters such as transportation, industry, tourism, settlements, and agriculture are the main factors that cause changes in water quality. Changes in water quality can be the beginning of pollution if the value of the water quality parameter has exceeded the seawater quality standard. One form of marine pollution is heavy metal pollution, and the metal most commonly found in coastal waters is lead (Pb). Therefore, the purpose of this study is to analyze the content of lead (Pb) on the coastal of Kupa Kupa Village, South Tobelo District, North Halmahera Regency. In this study, sampling was carried out using the purposive sampling method, where the water samples used were taken at predetermined points along the coastal waters of Kupa Kupa Village, South Tobelo District, North Halmahera Regency. Sampling of seawater was carried out using a sampling pole with a water depth of 5 m, then the samples were analyzed according to SNI 6989.8.2009. The results of the analysis are then described qualitatively. The results showed that the quality of the coastal waters of Kupa Kupa Village ranged from 32 – 34°C, salinity 27 – 34 ppt, pH 8.9 – 9.3, DO 7.88 – 7.91 mg/l, brightness 1 – 5.9 m, and current 0.05 – 0.12 ms-1. Meanwhile, the concentration of lead (Pb) in water in the coastal waters of Kupa Kupa Village, South Tobelo District, which is in the range of 0.50-0.78 mg/L, where this concentration has exceeded the seawater quality standards. Thus, the coastal waters of Kupa Kupa Village have been contaminated with lead metal which will be threatening for the life of marine biota and will also have an impact on human health.

Abstract

Mangrove ecosystems have potential both ecologically, economically, physically, and chemically, but pressure from anthropogenic activities has resulted in increased degradation of mangrove ecosystems. Poka Village has several mangrove areas that have been damaged either by land clearing or by industrial waste. Therefore, ecosystem restoration was carried out in the coastal waters of Poka Village using biodegradable materials (BESE-Elements), where this activity is a community service activity, in collaboration with the Maritime Center of Pattimura University and Wardeenburg Ecology - The Netherlands. This activity was carried out for 2 days, where the seeds and propagules used came from the nursery center in Passo Negeri, the BESE-Element used was a product brought from the Netherlands, the planting was carried out by groups of students, lecturers, and the Wardeenburg team, which consisted of the preparation stage BESE-Element, making layouts for planting points, planting seeds and propagules, and installing protective nets. The result of the activity is that mangrove ecosystem restoration is carried out in semi-enclosed areas using 10 BESE-Element. Each BESE-Element was planted with 10 mangrove seedlings consisting of 5 seedlings and 5 propagules with an average height of 30-40 cm, the spacing between BESE-Element was 60 cm. The types of mangrove species planted were Bruguiera gymnorrhiza, Rhizophora apicutala, and Rhizophora stylosa. Around BESE-Elements planted seedlings and mangrove propagules as a control for mangroves in BESE-Elements. The results of this activity are expected to be able to overcome the degradation of the mangrove ecosystem that has occurred in the coastal area of ​​Poka Village and have good implications for improving the condition of the mangrove ecosystem both physically, ecologically, and economically.
