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.

In the operation and maintenance of reverse osmosis (RO) systems, various challenges arise. One common issue faced is pressure fluctuations that can affect the quality of the produced water, shorten the lifespan of the membrane, and lead to system failure. This study aims to evaluate the performance of thin film composite spiral wound RO membranes in reducing Chloride ion (Cl-) and Total Dissolved Solids (TDS) levels in brackish water using low pressure. The RO membrane used in this research is made of polysulfone (PSF) with a thin film composite spiral wound type. The variables analyzed are the flow rate (Q) ranging from 1,000 to 2,000 mL/minute and the operational pressure (P) between 3.5 and 5 bar. The research results show that the RO membrane can reduce the Cl- level by 99.79% and TDS by 99.92% at a flow rate of 2000 mL/minute with an operational pressure of 5 bar. From the research findings, it can be concluded that an increase in operational pressure enhances the efficiency of reducing Cl- and TDS levels. This is due to the strong push on the feed that accelerates the salt penetration process through the membrane, which is then expelled through the retentate or wastewater stream. Abstrak Selama pengoperasian dan pemeliharaan sistem reverse osmosis (RO), berbagai tantangan muncul. Masalah yang umum terjadi adalah fluktuasi tekanan yang dapat mempengaruhi kualitas air yang dihasilkan, memperpendek umur membran dan menyebabkan kegagalan sistem. Penelitian ini bertujuan untuk mengevaluasi kinerja membran RO tipe thin film composite spiral wound dalam mengurangi kadar ion klorida (Cl-) dan TDS (Total Dissolved Solid) dalam air payau dengan menggunakan tekanan rendah. Membran RO yang digunakan dalam penelitian ini terbuat dari polysulfon (PSF) dengan jenis thin film composite spiral wound. Variabel yang dianalisis adalah laju aliran (Q) antara 1.000–2.000 mL/menit dan tekanan operasional (P) antara 3,5–5 bar. Hasil penelitian menunjukkan bahwa membran RO mampu mengurangi kadar Cl- sebesar 99,79% dan TDS sebesar 99,92% pada laju aliran 2.000 mL/menit dengan tekanan operasional 5 bar. Berdasarkan hasil penelitian, dapat disimpulkan bahwa peningkatan tekanan operasional meningkatkan efisiensi pengurangan kadar Cl- dan TDS. Hal ini disebabkan oleh dorongan kuat pada umpan yang mempercepat proses penetrasi garam melalui membran, yang kemudian dikeluarkan melalui aliran retenate atau air buangan.

Litopenaeus vannamei farming intensively cannot be separated from various problems. One of the problems faced by farmers is the availability of seeds in terms of quantity and quality. Therefore, this study aims to determine the production techniques of L. vannamei shrimp nauplii produced from the mass spawning process to support the increase in the number of L. vannamei shrimp production. Mass spawning has an impact on the number of nauplii produced and the effectiveness of broodstock maintenance. This study was carried out in Banten, Indonesia. This study was conducted by surveying and observing the stages of broodstock management, spawning, nauplii harvesting, and the production of nauplii. The results of the study showed that several aspects must be considered: (1) broodstock management that includes feeding and monitoring water quality, (2) mass spawning, and (3) harvesting and production of nauplii. During the rearing period, feed, such as pellets, marine worms, and squid, was administered to accelerate the gonad maturation process, and water quality was controlled. The results of mass spawning were obtained Maturation Rate ranges 12.66 - 21.66%, Matting Rate (MR) ranges 40 - 85%, Fecundity ranges 231,951 – 486,250 eggs/shrimp, Fertilization Rate (FR) ranges 60.45 – 72.37%, and Hatching Rate (HR) ranges 71.66 – 87.24%. Total nauplii production was 4.996.398 shrimp for 28 days. Total production was slightly lower than previously reported, which was caused by an inaccurate matting process.
