Abstract

Mangrove areas are widely reported as a place of abundance of microalgae producing omega-3 docosahexaenoic acid (DHA) and other bioactive materials of high economic value from the genus Aurantiochytrium. The search for microalgae was carried out in the mangrove area of Pari Island, Seribu Islands, Jakarta, in April 2022 and identified at the Biology Education Laboratory, FKIP UHAMKA. The purpose of this study is part of the long-term goal of collecting new strains or isolates from the genus Aurantiochytrium and other members of the family Thraustochytriidae from forests in Indonesian mangroves. This research was conducted by isolating microalgae with the pure streaking method and identifying them morphologically. This study succeeded in obtaining eight isolates (UHA1, UHA3, UHA5, UHA6, UHA10, UHA11, UHA12, and UHA13) which in the appearance of colonies and microscopic morphology lead to the species Aurantiochytrium sp. One of the isolates obtained (UHA12) was cultivated by batch culture for five days in an Erlenmeyer flask using glucose, yeasts extract, and seawater as a medium. The result is that the dry biomass obtained is almost equivalent to that of the Aurantiochytrium sp. other famous

Abstract

Thrautochytrids are often called heterotrophic microalgae that have a lot of omega-3 docosahexaenoic acid, or DHA. These microbes are found in many mangrove forest areas, including Indonesia, which has the biggest mangrove forests in the world. Indonesia is also beginning to look for useful microbes in these environments. The goal of this study was to find and identify a type of Thrautochytrid called Aurantiochytrium sp. in the mangrove forests of Tidung Island, part of the Thousand Islands near Jakarta. This area has never been studied for this type of microbe before. The study found two isolates of Thrautochytrids, named Aurantiochytrium sp. PTD5 and PTD6. These were identified by looking at the phylogenetic tree made from 18S rRNA sequences. The phylogenetic tree shows that PTD5 and PTD6 are closely related to other Aurantiochytrium strains like SR21 and BL10, which are widely used in research for making omega-3 DHA lipids.

Abstract

Abstrak: Masyarakat pulau Pari sudah tidak lagi membudidayakan rumput laut karena keadaan perairan yang semakin tidak kondusif. Alternatifnya, masyarakat saat ini menekuni pariwisata dan penginapan di pulau Pari. Salah satu keanekaragaman hayati yang terdapat di pulau Pari dan kurang disadari adalah kelimpahan dan potensi mikroalga. Masyarakat belum menyadari bahwa di pulau Pari terdapat mikroalga yang bernilai ekonomi tinggi yang memerlukan terobosan dalam pemanfaatannya dan juga pelestarian ekosistemnya. Pemandu wisata yang menjadi bagian dari masyarakat pulau diharapkan dapat mengedukasi jenis mikroalga dan manfaatnya terhadap warga lainnya maupun pengunjung pulau. Kegiatan pengabdian ini dilakukan dengan sosialisasi pemberian materi tentang mikroalga terhadap 21 warga pemandu wisata yang tergabung dalam ikatan Karang Taruna Unit 04 di Pulau Pari Kepulauan Seribu. Kegiatan diawali dengan pemberian soal pretest dan diakhiri dengan pemberian soal posttest. Perbedaan hasil dari skor yang diperoleh menjadi acuan dalam menentukan ada atau tidak adanya peningkatan pemahaman terhadap mikroalga ini. Angket pendapat diberikan demi mengevaluasi kegiatan untuk perbaikan ke depannya. Skor pretest yang diperoleh adalah 14,29 sedangkan posttest 20,95. Dengan demikian telah terjadi peningkatan pemahaman terhadap mikroalga. Harapannya dengan warga pemandu wisata yang memiliki wawasan terhadap mikroalga ini dapat mengedukasi masyarakat, wisatawan, dan pengunjung di pulau Pari akan pentingnya pelestarian perairan dan hutan mangrove sebagai habitat mikroalga serta membuka potensi peluang dalam mengembangkan produk berbahan dasar dari mikroalga.Abstract: The people of Pari Island are no longer cultivating seaweed due to increasingly unfavorable water conditions. As an alternative, people are currently pursuing tourism and lodging on Pari Island. One of the biodiversity found on Pari Island which is not recognized is the abundance and potential of microalgae. The community does not yet realize that on Pari Island there are microalgae that have high economic value which require a breakthrough in their utilization and also the preservation of their ecosystem. Tour guides, who are part of the island community, are expected to educate other residents and visitors about microalgae and their benefits. This community service activity involved providing outreach and training on microalgae to 21 tour guides from the Karang Taruna Unit 04 association on Pari Island, Seribu Islands. The activity begins with giving pretest questions and ends with giving posttest questions. The difference in the results of the scores obtained becomes a reference in determining whether or not there is an increase in understanding of this microalgae. Opinion questionnaires were given to evaluate activities for future improvement. The pretest score obtained was 14.29 while the posttest was 20.95. Thus there has been an increase in understanding of microalgae. The hope is that tour guides who have insight into microalgae can educate the public, tourists, and visitors on Pari Island about the importance of conserving waters and mangrove forests as microalgae habitats and open up potential opportunities in developing products made from microalgae.
