Macro and Micro Algae in Pollution Control and Biofuel Production – A Review

Fish waste is attracting growing interest as a new raw material for biopolymer production in different application fields, mainly in food packaging, with significant economic and environmental advantages. This review paper summarizes the recent advances in the valorization of fish waste for the preparation of biopolymers for food packaging applications. The issues related to fishery industry waste and fish by-catch and the potential for re-using these by-products in a circular economy approach have been presented in detail. Then, all the biopolymer typologies derived from fish waste with potential applications in food packaging, such as muscle proteins, collagen, gelatin, chitin/chitosan, have been described. For each of them, the recent applications in food packaging, in the last five years, have been overviewed with an emphasis on smart packaging applications. Despite the huge industrial potential of fish industry by-products, most of the reviewed applications are still at lab-scale. Therefore, the technological challenges for a reliable exploitation and recovery of several potentially valuable molecules and the strategies to improve the barrier, mechanical and thermal performance of each kind of biopolymer have been analyzed.

Recent Applications of Biopolymers Derived from Fish Industry Waste in Food Packaging.

Sustainable Development Goals are international agreements of many countries under UN initiation that have certain goals and targets. Achieving these goals and targets of the SDG requires a broad and focused effort from various sectors including higher education. Some of the goals associated with higher education are education, sanitation, innovation and global partnership. Given that higher education is one of the main drivers of the progress of a country, it gives university opportunities to play a bigger role. In addition, the rapid development and changes that occur today also require universities to respond quickly and appropriately. This can be done by developing university management based on the principle of SDG. This paper provides a brief description of the strategies that higher education institutions can take, particularly in responding to the changing world and in achieving the target of the SDGs. Five strategis for the university to encourage faster achievement of the targeted SDGs are proposed, i.e. Improvement of higher education quality, improvement of higher education equity, improvement of sanitarian and environment, improvement of research and innovation, and global partnership.

Sustainable development goals as the basis of university management towards global competitiveness

Desa Mororejo memiliki kawasan mangrove yang belum dimanfaatkan secara optimal. Salah satu upaya yang dapat dilakukan untuk mengoptimalisasi adalah dengan menjadikan kawasan ekowisata. Penelitian dilaksanakan dari bulan Agustus-November 2014 yang dilakukan melalui survei yang dilanjutkan dengan kegiatan pengamatan kondisi fisik kimia dan biologi kawasan, inventarisasi keanekaragaman fauna, analisis vegetasi, serta pengambilan data persepsi masyarakat lokal. Analisis data menggunakan analisis kesesuaian wisata mangrove dan analisis SWOT (Strengths–Weakness–Opportunity–Treats). Berdasarkan hasil penelitian, kawasan mangrove Desa Mororejo didominasi oleh tiga jenis mangrove yaitu Rhizophora mucronata,  Rhizophora stylosa, dan Avicennia marina. Fauna yang ditemukan antara lain burung, ikan, dan crustacea. Indeks kesesuaian untuk kegiatan wisata mangrove termasuk kategori sesuai bersyarat (63.24%). Strategi alternatif pengelolaan ekowisata mangrove yang diprioritaskan meliputi: melibatkan masyarakat lokal dalam kegiatan ekowisata (skor 2,834); meningkatkan peran serta Dinas terkait (skor 2.517); dan adanya zonasi wilayah supaya tidak terjadi gesekan dengan berbagai pihak (skor 2.25).  Mangrove areas at Mororejo village have not been optimally utilized. One effort to accelerate the optimalization of the area is by empowering its ecotourism. The study was conducted in August-November 2014 using a survey method, inventory of assorted fauna, vegetation analysis, and data collection of local community perception. Data analysis was conducted by feasibility analysis and SWOT (Strengths–Weakness–Opportunity–Treats) analysis to determine the alternatives strategy in exploring the potency of eco-tourism. Based on the result of this study, mangrove areas in Mororejo were dominated by three types of mangrove, i.e. Rhizopora mucronata, Rhizopora stylosa, and Avicennia marina. Fauna found in the areas were birds, fish, and crustacean. Feasibility index for mangrove tourism at mangrove areas at Mororejo village fell to category of conditionally feasible (63.24%). The alternative strategy in managing mangrove ecotourism at Mororejo village should involve the local community in handling ecotourism activities such as fishing activitity, birdwatching, and mangrove conservation (score 2.83); and also empower the related department (score 2.52), and zonation based areas should be implemented, therefore horizontal conflict could be avoided (score 2.25).

-Activities of aquaculture and industry which is directly adjacent to an aquatic environment may potentially result in increasing organic matter and causes a decreasing quality of water in it. Macrobenthos can be used as an bioindicators to detect environmental disturbances occur in the aquatic environment. This study aims to determine the level of environmental disturbance in aquatic environments using macrobenthic assemblages and their application in the abundance and biomass curves and it was compared to the values of diversity and similarity indices. Locations of this study is polyculture ponds and coastal of PT. Kayu Lapis Indonesian located in Mororejo Village, Central Java. Based on the abundance of macrobenthos results shows that in coastal area of PT. Kayu Lapis Indonesia is dominated by Cirratulidae (60%) from Polychaeta while in polyculture ponds is dominated by Potamididae (58%). Based on the abundance and biomass comparison (ABC) curves, the polyculture ponds were categorized as undisturbed area, whereas the coastal area of PT. Kayu Lapis Indonesia was categorized as moderately polluted for the second sampling time. Whilst the values of diversity (H’) and similarity (e) indices indicated low for all stations, the ABC curve of macrobetnhic assemblages is effective to  demonstrate the level of environmental disturbance occurs in aquatic environments.

Assessment of Water Quality Using Macrobenthos as Bioindicator and Its Application on Abundance-Biomass Comparison (ABC) Curves

Buku ini terdiri dari 9 Bab, membahas secara mendalam tentang peranan penting makrobenthos sebagai hewan invertabrata yang hidup di habitat dasar perairan. Pada tiga bab pertama membahas definisi, identifikasi serta interaksi antara makrobenthos dengan struktur sedimen, responsnya terhadap gangguan lingkungan, sehingga sesuai sebagai bioindikator perubahan lingkungan perairan, khususnya pengkayaan organik akibat aktivitas budidaya perikanan (aquakultur). Selain itu juga dibahas peranan ekologisnya dalam pembentukan habitat sedimen, antara lain menstimulasi dan meningkatkan proses mineralisasi materi organik, dan meningkatkan pertukaran partikel dalam lapisan batas antara air dan sedimen, sehingga berperan penting dalam rantai makanan melalui transfer karbon organik kembali ke ekosistem pelagis.
Bab IV khusus membahas teknik pengambilan sampel makrobenthos dengan beberapa alternatif alat yang umum digunakan (core sampler maupun grabs), desain eksperimen , dan untuk selanjunya dilakukan fiksasi, preservasi, sortasi, dan identifikasi serta enumerasi. Bab-bab berikutnya khusus membahas aplikasi pemanfaatan struktur makrobenthos dalam menentukan tingkat gangguan lingkungan, khususnya pada area budidaya, melalui analisis struktur dengan pendekatan univariat, multivariat, dan metode grafis serta indeks multimetrik. Pendekatan ini telah banyak diterapkan sebagai salah satu kriteria utama dalam menentukan kualitas lingkungan untuk manajemen akuakultur di berbagai negara. Sebagai sebuah buku ilmiah, ulasan dalam buku ini dapat menjadi salah satu referensi berharga bagi pemangku kepentingan mulai dari para aktivis do bidang perikanan, kelautan, teknik lingkungan, ilmu biologi terapan, sains terapan, pemerhati lingkungan, penentu kebijakan, pemda, para praktisi pembudidaya perikanan, serta masyarakat pada umumnya.
