Abstract

Seagrass transplantation in the large-scale requires a large number of seagrass individu from donor ecosystem. This may give negative impact as damage and reducing the number of seagrass in donor ecosystem. One of methods to overcome this case is by developing transplants using seagrass nut as source for seed. Substrate is one of factors that influence the growth of seagrass. The aim of this study was to compare the effect of differences in substrate composition on morphologi and growth of Enhalus acoroides seeds. Observations were carried out by treatment using mud, sand and mixed substrates sand with mud. The survival rate of Enhalus acoroides seeds was quite high of 100% but it had a lower value of 93.30% on sand substrate. The longest leaf is on the mud substrate with a length of 5.9 cm, the leaf width has the same size in each substrate with a value of 0.4 cm, the highest number of leaves were found in the sand and mixture substrate with 5 strands, the longest root size was in the mixed substrate with a length of 5 cm. The growth of Enhalus acoroides seagrass seeds did not show any significant difference. The highest growth was found in the mud substrate with a value of 0.10 cm/day. Keywords: Enhalus acoroides, seagrass,seed, substrate, transplantation

Abstract. The richness of biological diversity is an asset for the development and prosperity of the nation, but human needs and environmental pressure increased, especially marine biological resources, it has resulted in a decline in the population of several marine life. This causes several marine life to be rare and endangered. Conservation efforts need to be carried out covering aspects of preservation, protection, and utilization. Another preventive way that can be done is providing education to the community, especially in the elementary school young generation. Given that education related to the preservation of marine biodiversity is important to learn as early as possible, elementary school young generation are the main target for socialization about protected marine life to create a sense of care, willingness, and knowledge so that marine wealth can be preserved. Introduction of protected marine life in the Riau Islands region with participants of grade VI students at the State/Public Elementary School (SDN) 06 Gunung Kijang, Bintan Regency. The activity is carried out in several stages, namely pre-test knowledge of protected marine life, education of protected marine life in the Riau Islands region (video and pocketbook containing short stories and information on protected marine life in Riau Islands), and post-test to know enhancement of student knowledge of protected marine life. The level of understanding increased from a range of poor-moderate understanding by pre-test correct answers (47% -79%) to a moderate-high range of understanding by post-test correct answers (74% -100%).             Abstrak. Kekayaan keanekaragaman hayati menjadi aset bagi pembangunan dan kemakmuran bangsa, namun dengan meningkatnya kebutuhan manusia dan tekanan terhadap lingkungan khususnya sumberdaya hayati laut, mengakibatkan terjadinya penurunan populasi beberapa biota perairan. Hal ini menyebabkan beberapa biota perairan menjadi langka dan terancam punah. Upaya konservasi perlu dilakukan yang meliputi aspek pelestarian, perlindungan, dan pemanfaatan. Cara preventif lain yang dapat dilakukan adalah pemberian edukasi kepada masyarakat khususnya anak-anak sekolah. Mengingat pendidikan terkait kelestarian keanekaragaman hayati laut penting untuk dipelajari sedini mungkin, maka anak-anak sekolah dasar menjadi sasaran yang tepat untuk dilakukan sosialisasi mengenai biota-biota laut yang dilindungi agar terwujudnya rasa peduli, kemauan, serta ilmu pengetahuan sehingga kekayaan laut dapat terjaga. Pengenalan biota laut dilindungi di wilayah Kepulauan Riau dengan peserta siswa-siswi kelas VI di Sekolah Dasar Negeri (SDN) 006 Gunung Kijang, Kabupaten Bintan. Kegiatan dilaksanakan dalam beberapa tahap, yaitu pre test pengetahuan tentang biota laut yang dilindungi, edukasi biota laut yang dilindungi di wilayah Kepulauan Riau (media video dan buku saku yang berisi cerita pendek serta keterangan biota laut dilindungi yang ada di Kepulauan Riau), dan post test pengetahuan tentang biota laut yang dilindungi. Tingkat pemahaman meningkat dari rentang pemahaman yang kurang sampai sedang dilihat dari persentase jawaban benar pre-test sebesar 47%-79% menjadi rentang pemahaman sedang sampai tinggi dengan hasil jawaban benar post-test sebesar 74%-100%.

Abstract

Siput gonggong, Laevistrombus turturella termasuk komoditas perikanan laut yang memiliki nilai ekonomi tinggi di Pulau Bintan Provinsi Kepulauan Riau. Hemolim pada siput berperan penting dalam sistem pertahanan tubuh dan reproduksi. Penelitian ini bertujuan untuk mengetahui total hemosit dan diferensial hemosit pada siput gonggong asal Pulau Bintan. Penelitian dilaksanakan pada bulan Juli-Agustus 2021. Sampel siput gonggong berasal dari perairan laut Kampung Madong dan Lobam. Hemolim diambil dari otot kaki gonggong untuk pemeriksaan total hemosit dan diferensial hemosit. Data dianalisis secara deskriptif. Hasil penelitian menunjukkan total hemosit, persentase hyalin dan sel granular siput gonggong dari Kampung Madong dan Lobam relatif sama dan dalam kisaran normal (< 1,0 x 106 sel/mm3). Jumlah total hemosit siput gonggong asal Kampung Madong dan Lobam secara berturut-turut adalah berkisar antara 77.000-166.600 sel/mm3 dan 71.000-165.000 sel/mm3, persentase sel hyalin berkisar antara, 58%-80% dan 52%-70%, serta persentase sel granular berkisar antara 20%-42% dan 30%-48%. Oleh karena nilai total hemosit dan diferensial hemosit relatif sama maka siput gonggong asal Kampung Madong disarankan sebagai kandidat calon induk karena memiliki ukuran tubuh 6,52 ± 5,61 cm lebih besar dibandingkan asal Lobam 5,27 ± 0,40 cm.Gonggong conch, Laevistrombus turturella is a marine gastropod highly valued as a seafood commodity in Bintan Island Riau Islands Province. The farming technology of the species is currently not available due to limited information on its biology including its immune system and reproduction. Hemolymph in conchs plays an important role in gonggong conch body’s defense system and reproduction. This study aimed to determine the total haemocytes and hemocytic differential of gonggong conchs originated from Bintan Island. The research was conducted between July-August 2021. The gonggong conch samples were collected from the coastal waters of Kampung Madong and Lobam. Hemolymph was taken from the gonggong conch leg muscles for examination of total hemocytes and hemocytic differential and analyzed descriptively. The results showed that the total hemocytes, percentage of hyaline and granular cells of gonggong conchs from Kampung Madong and Lobam were relatively similar and within the normal range (< 1.0 x106 cell/mm3). The total number of haemocytes of gonggong conchs from Kampung Madong and Lobam ranged from 77,000-166,600 cells/mm3and 71,000-165,000 cells/mm3; respectively, while the percentages of hyaline cells ranged between 58%-80% and 52%-70%, respectively, and the percentage of granular cells ranged between 20%-42% and 30%-48%. Gongong conch from Kampung Madong had a body size of 6.52 ± 5.61 cm which was larger than that of Lobam with body size of 5.27 ± 0.40 cm. Because both had relatively similar values of total haemocytic and haemocytic differential, the gonggong conch from Kampung Madong was suggested as the best candidate for broodstock.

Abstract

Sea cucumbers which have the scientific name Holothuroidea are fishery commodities that have high economic value and are in great demand in the global market. Sea cucumbers are the main commodity of Benan Village which is the outermost island of Lingga district. Most of the people in Benan Village work as sea cucumber fishermen. As an aquatic resource owned by the village, sea cucumbers are still constrained in terms of handling so that it reduces the selling value of the dried sea cucumbers produced. Therefore, it is important to empower the people of Benan Village regarding the postharvest handling of sea cucumbers which aims to improve the quality as well as directly increase the selling value of that resources. Community empowerment activities are expected to add insight and improve the ability of the Benan Village community in handling sea cucumbers post-harvest. Empowerment was carried out through three methods, namely the distribution of questionnaires and discussions in the form of questions and answers with the Benan Village community group regarding the problem process in handling post-harvest sea cucumbers, which was carried out after distributing questionnaires to the sea cucumber aquaculture community, then education and discussion on good procedures were carried out in post-harvest handling. To improve the quality of this sea cucumber commodity, then in the third stage, mentoring and practice regarding the correct handling of sea cucumbers is carried out to produce good quality sea cucumbers from washing to packaging. The selection of discussion methods, lectures/education, and direct practice is considered effective in increasing public knowledge about the process of handling sea cucumbers postharvest properly and correctly, considering that the target stakeholders are sea cucumber farmers.

Abstract

Salah satu penyakit yang menyerang udang vaname adalah penyakit White Spot yang disebabkan oleh White Spot Syndrome Virus (WSSV). Dibutuhkan upaya untuk mencegah penyebaran dari WSSV pada budidaya udang yang efektif, salah satunya adalah dengan pemberian pakan mengandung ekstrak G. verrucosa. Penelitian ini bertujuan untuk menguji pengaruh pakan mengandung ekstrak G. verrucosa dengan dosis yang berbeda terhadap kelangsungan hidup udang vaname yang diinfeksi WSSV. Penelitian ini terdiri dari enam perlakuan dosis G. verrucosa dan masing-masing tiga ulangan, yaitu KN (tanpa ekstrak), KP (tanpa ekstrak + infeksi WSSV), A (ekstrak 2.000 mg/kg + infeksi WSSV), B (dosis 3.000 mg/kg + infeksi WSSV), C (dosis 4.000 mg/kg + infeksi WSSV), dan D (dosis 5.000 mg/kg + infeksi WSSV). Udang vaname dengan bobot 6-10 g/ekor dipelihara dalam akuarium dengan ukuran (60×30×30) cm dengan padat tebar 10 ekor/akuarium. Udang diberi pakan (protein 32%) yang mengandung ekstrak G. verrucosa dengan feeding rate 3% dari bobot biomassa sebanyak tiga kali sehari selama 14 hari. Pada hari ke-15 diuji tantang dengan WSSV dengan dosis 0,1 mL/ekor secara intramuskular. Hasil penelitian menunjukkan bahwa pakan mengandung ekstrak G. verrucosa mampu meningkatkan kelangsungan hidup udang vaname secara signifikan dibanding perlakuan kontrol positif. Kelangsungan hidup terbaik pasca uji tantang pada perlakuan C (4.000 mg/kg), yaitu 56,67±5.74%. Disimpulkan bahwa dosis 4.000 mg/kg pakan memberikan hasil terbaik untuk meningkatkan kelangsungan hidup udang vaname yang diinfeksi WSSV.
