Ekosistem mangrove memiliki sejumlah manfaat dan jasa ekosistem, namun keberadaannya terus memperoleh tantangan dan tekanan akibat aktivitas di wilayah pesisir. Penelitian ini bertujuan menganalisis kondisi ekosistem mangrove dan konsekuensinya terhadap jasa ekosistem di kawasan ekosistem Mangrove Angke Kapuk Teluk Jakarta. Kondisi ekosistem dianalisis dengan mengkaji tutupan lahan dan tingkat kekritisan lahan mangrove menggunakan citra SPOT 6 dan Sistem Informasi Geografi, sedangkan konsekuensinya terhadap jasa ekosistem dikaji dengan analisis deskriptif. Hasil analisis menunjukkan luasan ekosistem Mangrove Angke Kapuk sebesar 291,17 ha dengan tingkat kerapatan 272,79 ha jarang, 16,83 ha sedang dan 1,54 ha lebat. Ekosistem mangrove yang masih terlihat terjaga sebagian besar berada pada kawasan Suaka Marga Satwa Muara Angke dan Hutan Lindung Angke Kapuk, meskipun demikian posisinya sangat dekat dan berada diantara kawasan permukiman dan infrastruktur lainnya. Kondisi kawasan ekosistem Mangrove Angke Kapuk berdasarkan tingkat kekritisan lahan mangrove terkategori rusak 272,79 ha dan 18,38 ha terkategori tidak rusak. Kawasan ekosistem Mangrove Angke Kapuk berpotensi terus mengalami tekanan terutama disebabkan aktivitas dari area terbangun di sekitarnya. Kondisi tersebut juga akan berkonsekuensi terhadap menurunnya jasa ekosistem yang tersedia. Jasa ekosistem mangrove yang sediakala masih dirasakan menjadi semakin berkurang atau bahkan hilang sehingga pada akhirnya dapat menyebabkan ketidaknyamanan, kerugian ekonomi dan ancaman bencana. Keberadaan kawasan ekosistem Mangrove Angke Kapuk di pesisir utara Jakarta perlu mendapat perhatian karena masih berkontribusi memberikan jasa ekosistem dan menjaga kelestarian lingkungan.

Saponins are compounds derived from plants that are currently widely used in aquaculture for aquatic pest control. In this study, potential saponin components extracted from fish poison tree (Barringtonia asiatica), which is widely dispersed in tropical areas worldwide, were characterized. Saponin properties were obtained from seeds and leaves by extraction and spectrophotometric methods. To test its properties, four different concentrations of saponin extracts, namely 10 ppm, 20 ppm, 30 ppm, and 40 ppm, were applied in four trials containing 20 tilapias each. An unexpected result was obtained and proved that the saponins extracted from the seeds of the fish poison tree proved to be significantly more effective than the saponins extracted from the peel of its fruit to eradicate pest in pond. The results also revealed that the lethal dose of saponins reached higher level at a concentration of 40 ppm. It can be concluded that fish poison tree as a poisonous tree plays an important role in ensuring the sustainability of saponin stocks. The use of natural materials such as fish poison tree as a biopesticide has the potential to minimize environmental damage and reduce costs for aquaculture.

Daun kelor (Moringa oleifera) merupakan bahan baku lokal yang memiliki kandungan protein nabati sebesar 21,49% sehingga dapat dijadikan alternatif dalam penyusunan formulasi pakan buatan. Potensi penggunaan daun kelor sebagai bahan baku dalam formulasi pakan dapat dilakukan dalam bentuk silase. Penelitian ini bertujuan mengetahui pengaruh penggunaan dan persentase silase daun kelor dalam formulasi pakan terhadap efisiensi nutrient dan pertumbuhan ikan nila (Oreochromis niloticus). Penelitian dilakasana dengan menggunakan metode Rancangan Acak Lengkap dengan 4 perlakuan dan 3 kali ulangan. Penelitian dilakukan dengan mengindetifiksi potensi silase daun kelor, persiapan pakan perlakuan dan uji biologi terkait efesiensi nutrient dan pertumbuhan ikan nila. Hasil penelitian menunjukan pemanfaatan silase daun kelor memiliki potensi yang sama seperti pakan komersial terhadap efisiensi nutrient dan pertumbuhan ikan nila. Nilai efisiensi nutrient tidak menunjukan perbedaan signifikan antara pakan formulasi silase dan tanpa silase daun terhadap rasio konversi pakan dan retensi energi (P>0.05), sebaliknya mengalami perbedaan signifikan terhadap rasio efisiensi protein (P<0.05). Pertumbuhan ikan nila yang diperoleh tidak menunjukan perbedaan signifikan antara formulasi silase dan tanpa formulasi terhadap pertumbuhan bobot mutlak, Laju Pertumbuhan Spesifik (LPS) dan tingkat kelangsungan hidup (P>0.05), hal ini menujukan bahwa kualitas pakan formulasi silase sama dengan pakan tanpa formulasi tapi memiliki tingkat rasio efisiensi protein yang rendah.
