Abstract

Makroalga sudah menjadi salah satu ciri khas komoditas perikanan budidaya di pesisir Kabupaten Kupang sejak insepsinya awal tahun 2000-an. Adapun tujuan review ini untuk untuk memberikan gambaran sosial dan ekonomi tentang praktek sukses maupun kegagalan budidaya rumput pesisir Kabupaten Kupang. Penelitian ini dilakukan di empat kecamatan pesisir Kabupaten Kupang, yakni Kupang Barat, Semau, Semau Selatan, dan Sulamu. Sembilan desa dan 27 responden terpilih secara acak untuk pengumpulan data melalui aplikasi Android ODK (Kobo Collect©). Secara umum, setelah dua dekade berjalannya budidaya rumput laut di Kabupaten Kupang ternyata telah memberikan kontribusi pada kesejahteraan bagi masyarakat pesisir. Masyarakat paling banyak memilih metode tali tunggal panjang (monoline/longline). Pada awalnya masyarakat pesisir menjadikan aktivitas ini sebagai alternatif saja, sekarang telah menjadikannya sebagai sumber pendapatan utama keluarga. Kecamatan Semau dan Kupang Barat tercatat sebagai daerah dengan produkktivitas paling tinggi pesisir Kupang berbanding terbalik dengan tingkat pendidikan yang lebih rendah di kedua kecamatan tersebut. Aktivitas padat karya dicirikan dengan lebih dari setengah keterlibatan anggota keluarga dalam proses budidaya. Tenaga kerja tergolong masih dalam usia produktif yaitu rata-rata 49 tahun bagi wanita dan 50 tahun bagi pria. Namun yang masih menjadi kendala adalah pemakaian repetitif propagul vegetatif serta pemakaian spesies tunggal.

Abstract

ABSTRACTAccurate and reliable identification of macroalgae has a crucial role in a range of research relating to the interaction and function of macroalgae in reef ecosystems. The dependency on identifying macroalgae on fresh samples places severe constraints on conducting this research leading to potential biases due to the selection of sites either close to shore or in the vicinity of fully equipped research stations. Therefore, this study aimed to determine if could reliably be used silica bead-dehydrated samples to identify genera characteristics that are only visible in sectioned material. Fresh macroalgal samples were collected at Nelly Bay, compared to Magnetic Island. Materials and sections were to previously collect macroalgal samples and sections dehydrated in silica beads while in the field and reconstituted in filtered seawater for identification. Each sample was identified using histological sections supported with visual tools (photograph, herbaria). In this study, macroalgal identified samples from all species to genus with characteristic features recognizable within both fresh and reconstituted samples. No artifacts were present in reconstituted macroalgal samples compared to freshly collected samples. Therefore, it is suggested that using silica beads as a preservation field method for collecting and identifying macroalgal samples is a suitable and accurate alternative method to the use of fresh samples, which eliminates the time and distance constraints associated with fresh samples.Keywords: Great Barrier Reef, Histological sectioning, Macroalgae identification, Silica-beads preservation, Reconstituted

Abstract

Abstrak – Potensi sumberdaya kelautan Indonesia sangatlah besar ditunjang oleh keanekaragaman biologi dan kimia (biochemo-diversity) untuk penemuan berbagai bahan alam yang dapat dimanfaatkan sebagai sumber bahan farmasi, nutrisi, maupun bahan baku industri lainnya. Tinjauan ini akan memaparkan sejarah bahan alam laut, lalu diikuti dengan deskripsi kekayaan biologi dan kimiawi Indonesia dari organisme laut, dan diakhiri dengan uraian tentang status dan potensi bahan alam dari makroalga Indonesia. Sudah terdapat minimal enam bahan alam yang sudah secara komersil sebagai antivirus, anti cancer, dan anti HIV. Sejak awal dekade 90-an, terdapat beberapa bahan alam laut Indonesia yang berasal dari organisme seperti, spons, intertebrata laut, maupun jamur. Makroalga laut masih menyimpan potensi lebih jauh karena eksplorasi yang masih terbatas pada zona intertidal. Kata Kunci: Bahan alam laut, Biokimia diversitas, Makroalga Abstract – The potential of Indonesia's marine resources is very vast, supported by biological and chemical diversity (biochemo-diversity), for the discoverying of various natural materials that can be used as a source of pharmaceutical, nutritional, and other industrial raw materials. This review will describe the history of marine natural materials, followed by a description of Indonesia's biological and chemical richness of marine organisms, and ends with a description of the status and potential of Indonesian macroalgae natural products. There are already at least six natural products that have been commercially used as antiviral, anti-cancer, and anti-HIV. Since the early 90s, there have been several Indonesian marine natural materials derived from organisms such as sponges, marine invertebrates, and fungi. Marine macroalgae still have further potential because exploration is still limited to the intertidal zone. Keywords: Biochemo diversity, Macroalgae, Marine natural products

Abstract

The research describes how molecular networking was used as a screening tool to prioritize the isolation workflow of 40 macroalgae sampled from West Timor waters, Indonesia, in addition to a Nuclear Magnetic Resonance-based (NMR) spectroscopy strategy. A mass spectrometry (MS) was employed to generate spectra that later be used as data to produce the molecular network with the Global Natural Product Social Molecular Networking (GNPS) website. The screening process used the molecular network, which assisted in the selection of six samples of macroalgae out of the 40 samples for further examination. Lastly, an NMR-based protocol was employed to choose the samples of interest to be investigated further. Six samples were shortlisted from the GNPS molecular network based on specimens, which were then validated with 1H NMR spectroscopy to finally prioritized three samples.

Abstract

Indonesia sebagai negara kepulauan sangat diuntungkan karena berada di posisi daerah dengan iklim tropis, sehingga terdapat banyak keanekaragaman hayati yang melimpah.Rumput laut Kappaphycus alvarezii merupakan salah satu jenis rumput laut penghasil karaginan jenis kappa yang cukup tinggi. Tujuan penelitian ini adalah untuk mengetahui presentasi rendemen karaginan rumput laut sentra produksi Kabupaten Maluku Barat Daya, Provinsi Maluku dan mengetahui jenis karaginan rumput laut sentra produksi Kabupaten Maluku Baraat Daya, Provinsi Maluku. Metode yang digunakan dalam penelitian ini adalah menggunakan metode survey di beberapa lokasi perairan di Kabupaten Maluku Barat Daya dengan cara mengambil sampel rumput laut. Proses ekstraksi rumput laut dilakukan dengan memasak sampel rumput laut kering dalam larutan KOH 4% sebanyak 3 ml dan dicampurkan dengan larutan aquades sebanyak 25 ml selama kurang dari 30 menit sampai rumput laut larut dengan suhu 70-90°C. Hasil penelitian menunjukan rendemen karaginanpada perairan Luang Timur dengan nilai 16,6% diikuti perairan Luang Barat 13,88%, dan perairan Ustutun dengan rendemen 5,76%. Hasil penelitian juga menunjukan hasil identifikasi gugus fungsional tersebut juga dapat disimpulkan bahwa jenis karaginan yang dihasilkan adalah jenis kappa karaginan karena mengandung gugus D-galaktosa-4-sulfat dan 3,6 anhidro-D-galaktosa serta tidak mengandung gugus D-galaktosa-2-sulfat dan gugus 3,6 anhidrogalaktosa-2-sulfat.Kata kunci : Rumput laut, Kappaphycus alvarezii, Karaginan, Ekstraksi, Rendemen

Abstract

One field of science that has been developing rapidly in recent decades is the field of bioinformatics. Advances in the rapidly growing field of information technology make it easier for someone to access and analyze information from several database sources that store biological data throughout the world via websites. Apart from that, the distribution of Bioinformatics Application programs via the internet can now help pupils, students, teachers, lecturers and researchers in solving biological problems by using various database sources and software for various needs, including learning needs. Community service activities in the form of training at SMAS Muhammadiyah Kupang were held on Saturday, May 18 2024. The methods used were presentation of material and training related to bioinformatics as well as pre-tests and post-tests to determine students' abilities.
