Sponge makin banyak menarik perhatian para ilmuwan di seluruh dunia bukan karena potensi bioekologisnya saja tetapi juga karena potensi kosmetik dan biomedis dari molekul-molekul bioaktif maupun biomaterial sponge. Sangat disayangkan, pengetahuan tentang diversitas sponge di wilayah dengan biodiversitas tertinggi di dunia seperti Sulawesi Utara dan Wallacea pun masih sangat miskin dengan sebagian informasi diversitas sponge wilayah-wilayah ini tersebar dalam literatur-literatur ilmiah yang sudah usang dan terfragmentasi. Studi ini bertujuan untuk meningkatkan pengetahuan taksonomi dasar sponge di Sulawesi Utara khusunya di perairan Tahuna Kepulauan Sangihe sekaligus memberikan gambaran umum tentang distribusi dan potensi farmakologis dari sponges yang umum ditemukan di perairan Tahuna. Menggunakan metode acid digestion dan kombinasi mikroskop cahaya dan Corel Draw, kami mengidentifikasi tujuh spesies umum di terumbu karang Tahuna yaitu Agelas nakamurai, Clathria reindwardtii, Ircinia strobilina, Melophus sarasinorum, Speciospohongia vagabunda dan Xestospongia testudinaria. Selain menyentil tentang molekul-molekul bioaktif, tulisan ini juga secara singkat membahas tentang penyebaran ketujuh jenis sponge itu terutama di kawasan Asia Tenggara, selatan Jepang dan Australia untuk memperlihatkan sebaran sekaligus potensi kandungan bioaktif dan biomaterial dari sumberdaya laut amat berharga tetapi terabaikan dalam berbagai program monitoring dan konservasi terumbu karang di Indonesia ini. Sementara M. sarasinorum, S. vagabunda C. reinwardti, dan X. testudinaria terlihat memiliki distribusi sangat luas di wilayah Indo Pasifik, Agelas nakamurai dan I. strobilina sejauh ini baru dilaporkan di perairan Okinawa, Asia Tenggara dan Wallacea meskipun spesies serupa dari kedua genus itu terdistribusi hampir di seluruh Australia. Artikel ini mewakili laporan pertama tentang diversitas, kandungan molekul dan sebaran geografis sponge umum dari perairan Kabupaten Sangihe. Sponges have attracted considerable attention not only because of their bioecological but also due to cosmetical and medical potentials of bioactive compounds and biomaterials from sponges. Unfortunately, the basic knowledge of this impressive marine invertebrate, even in rich biodiversity region such as North Sulawesi, remains poorly known with such information scattered in old and fragmented literatures. This research aimed to increase the basic taxonomic knowledge and medical potential of seven sponges in Tahuna’s coral reefs Sangihe Islands as an step to encourage monitoring and concervation of this key species in coral reef in Sangihe Islands. Using acid digestion method and combination of light microscope and Corel Draw, we identified seven common species in Tahuna’s coral reefs namely reinwardti, Ircinia strobilina, Melophus sarasinorum, Speciospongia vagabunda and Xestospongia testudinaria. In addition to providing a quick review on the distribution of these species especially in South East Asia, southern Japan and Australia, the authors also touched on bioactive compounds produced by these animal isolated by one of the authors either from Sangihe Island’s sponges or sponges from other locations to give an overview of the bioactive potential and geographical distributions of the impressive but ignored marine resource in coral reefs’ monitoring and conservation programs in Indonesia. While sepecies such as M. sarasinorum, S. vagabunda C. reinwardti, and X. testudinaria seem to well distributed in Indopasific, A. nakamurai and I. strobilina are distributed only in south Japan and Wallacea regions although the sibling species of the two sponges have been well reported throughout Australia. This article represents the first report on biodiversity, distribution and bioactive molecules of sponges from Sangihe Islands.

Masyarakat Kelurahan Santiago Kecamatan Tahuna Kepulauan Sangihe merupakan daerah yang penduduknya mayoritas bermata pencaharian sebagai nelayan. Kurangnya pengetahuan tentang penanganan hasil perikanan secara efektif dan efisien membuat hasil tangkapan masyarakat nelayan kelurahan Santiago mengalami penurunan kualitas dan itu sangat berpengaruh pada penurunan harga jual. Akibatnya pendapatan dan tingkat kesejahteraan menurun. Kegiatan ini bertujuan untuk memberikan pengetahuan kepada masyarakat nelayan dalam menemukan pemecahan masalah di kelurahan Santiago Kecamatan Tahuna Kepulauan Sangihe. Nelayan harus dibekali dengan pengetahuan bagaimana menangani hasil-hasil tangkapan agar memperolah nilai jual yang relatif tinggi. Salah satu usaha agar produk hasil tangkapan tetap berkualitas adalah penanganan dengan sistem rantai dingin (Cold Chain System) mulai dari pasca panen sampai pada konsumen. Metode yang dilakukan yaitu pelatihan melalui ceramah dan diskusi memberikan pandangan kepada masyarakat akan pentingnya penanganan pasca tangkap untuk mempertahankan mutu dalam keadaan dingin sehingga tidak mudah busuk.

Kolam terpal merupakan wadah budidaya ikan yang tepat untuk pembesaran ikan nila karena berbagai keunggulannya seperti kemudahan memindahkan, keramahan terhadap konstruksi tanah, kesesuaian dengan karakteristik ikan nila, kemudahan membersihkan kolam dan memanen ikan. Kegiatan pengabdian kemitraan masyarakat ini menyasar kelompok-kelompok masyarakat di Kampung Tariang Lama, Kecamatan Kendahe yang masyarakatnya sulit mendapatkan ikan disaat cuaca buruk di laut. Pengabdian kepada masyarakat ini mencakup kunjungan lapangan (survei), penyuluhan, pelatihan, evaluasi, dan pemantauan pasca penyuluhan dan pelatihan. Sejauh ini, kelompok masyarakat sasaran pengabdian di Kampung Tariang Lama sudah mampu merancang, membuat sendiri kolam, dan mampu membudidayakan ikan nila menggunakan kolam terpal. Selanjutnya, hasil evaluasi dan pemantuan menunjukan bahwa masyarakat Tariang Lama tidak menghadapi kendala berarti dalam membudidayakan ikan di kolam terpal. Sebagian dari mereka bahkan berusaha merancang dan membangun sendiri kolam terpal secara mandiri hal ini merupakan indikasi kuat dari keterbukaan dan penerimaan masyarakat Tariang Lama terhadap penerapan teknologi budidaya ikan yang masih relatif baru untuk masyarakat Tariang Lama ini. Tarp-typed pond or tarpaulin pond is an appropriate medium for cultivation of Nile tilapia because of its many advantages including (1) easily moved from one place to another,(2) friendly toward soil construction, (3) suitable with tilapia’s characteristics and (4) very convenient forcleaning and harvesting. This community service focused on societal groups in Tariang Lama Village, Kendahe district whose society normally have difficulty in obtaining fish during stormy sea. This community service consisted of (1) field survey, (2) mentoring, (3) training and (4) evaluation/monitoring. The targeted societal groups in Tariang Lama were already capable of designing, building their own tarp-typed pool and cultivating Nile tilapia with tarpaulin pond. In addition, evaluation and monitoring showed that the people of Tariang Lama had no problem in adopting fish cultivation technique with tarpaulin pond. Many of them even designed and built their own tarp-typed pond, strongly suggesting the openness and acceptance of the people of Taring Lama towards the implementation of the relatively new fish farming technique.
