Cemaran logam berat seperti Cu dan Hg di Pantai Timur Surabaya (Pamurbaya) dikhawatirkan memberikan dampak terhadap kualitas perairan. Mangrove yang tumbuh di Pamurbaya dapat digunakan sebagai indikator cemaran logam berat. Kemampuan mangrove dalam mengakumulasi logam berat ditunjukkan melalui nilai bioakumulasi (BAF), biokonsentrasi (BCF), dan translokasi faktor (TF). Salah satu mangrove yang terdapat di Pamurbaya adalah R.mucronata. Mangrove inimemiliki akar penyangga, selain fungsinya untuk membantu tegaknya pohon, akar jenis ini juga dapat menahan dan memantapkan sedimen tanah, sehingga mencegahtersebarnya bahan pencemar ke area yang lebih luas. Penelitian ini bertujuan untuk mengidentifikasi bioakumulasi cemaran logam berat Cu dan Hg pada mangrove R. mucronata, air, dan sedimen di Pantai Timur Surabaya. Sampel penelitian diambil pada tiga lokasi melalui purposive sampling. Analisis logam berat Cu dan Hg menggunakan metode Atomic Absorption Spectroscopy (AAS) dan parameter fisika-kimia oseanografi diukur secara in situ dengan pengulangan sebanyak 3 kali. Hasil penelitian menunjukkan kadar logam berat Cu pada air lebih tinggi dibandingkan sedimen berturut-turut Stasiun 1>Stasiun 2>Stasiun 3. Hasil cemaran logam Hg pada mangrove R. mucronata, air dan sedimen menunjukkan nilai di bawah baku mutu dengan kisaran 0,0004< Hg<0,0006 ppm. Berdasarkan perhitungan nilai bioconcentration factor (BCF) dan translocation factor (TF), diketahui bahwa kemampuan mangrove R.mucronata sebagai tumbuhan excluder dan fitoekstraksi sehingga mampu mengurangi polutan logam berat dari lingkungan melalui proses penyerapan melalui akar dan translokasi menuju daun.

Mangroves are plants that can live in salty waters and areas tidal. Sediments store more than 50% of the carbon contained in the coastal ecosystem. This study aims to calculate the value of the content of carbon and soil density values. This research uses purposive sampling to determine the location and the LOI (loss on ignition) method to find out carbon content. Station 1 is located at Ecowista Mangrove, Station 2 is at ponds, and Station 3 on the coast. Sediment organic carbon percentage value Soil is obtained from the process of ashing soil organic matter. Average value the highest percentage of soil organic carbon content at all stations is located at a depth of 60- 100 cm, which is equal to station 1 (14.38%) and the estimated carbon The highest organic matter is located at station 1 at a depth of 60-100 cm (95,151 Mg/ha), for the highest overall organic carbon estimation is located at station 3 (252,900 Mg/ha). From the results obtained for the value of mangrove density and production Mangrove litter can be said to have a mutual influence on the carbon value organic sediment at a depth of 0-30 cm.

Mangrove forests are forests that are able to store carbon and absorb carbon dioxide with the best ability compared to other forests. This study aims to analyze the condition of the mangrove forest and to analyze the estimation of carbon stock and carbon dioxide uptake from tree stands and saplings in the Gunung Anyar mangrove forest. The main data needed in this research is the number of individuals and the amount of biomass of mangrove stands. The research method used is the survey method. Determination of the location and sampling technique was carried out by purposive sampling with 3 transect lines (Transect Line Plot). Estimation of carbon stock and carbon dioxide uptake was done by non-destructive method and allometric equation approach. The condition of the Gunung Anyar mangrove forest for tree stands was damaged, while the saplings were good, the dominant type of mangrove was Avicennia marina. The estimated carbon stocks of tree stands and saplings were 38.67 tons C/ha and 9.26 tons C/ha, respectively. The carbon absorption of tree stands and saplings was 71.25 tons CO2/ha and 34.99 tons CO2/ha.

One of the habits of the people that are difficult to get rid of is throwing garbage. The trash the community throws away will be exposed to seawater during high tide and spread widely. Plastic waste stuck in mangroves can also block the sunlight that mangroves need to grow even though the functions of mangroves are essential, such as preventing erosion, and abrasion, shelter for some biota, and many more. Based on this background, researchers wanted to know the effect of plastic waste on the abundance of mangrove seedlings. This study aimed to determine the effect of plastic waste cover on the growth of mangrove seedlings and the impact of plastic waste on the abundance of mangrove seedlings in Tambak Wedi Surabaya. The method used was sampling vegetation on a transect measuring 2x2 m for seedlings, 5x5 m for saplings, and 10x10 m for trees at different locations and calculating the area covered by plastic waste at each station. From the observations, data obtained at each station showed that the plastic waste covering the mangrove area, the amount of plastic waste at each station was 139.4 – 144.6 m2, the density of mangroves at three stations was 14,700 ind/ha, and for the average density of seedlings at each station of 26,666 ind/ha. When viewed from the standard criteria for mangrove damage, the density of mangrove seedlings in the Wedi Pond area is quite good.

Indonesia has the largest mangrove forest in the world. In addition, Indonesia is also a country with the largest number of mangrove species in the world. This creates a huge potential in the utilization of mangroves in many areas of life, one of them is in the health field. Where, the majority of the plants widely used in the health sector are land plants. Charcoal has been used in the field of health for thousands years. Charcoal generally utilized in the field of health in the form of activated charcoal. Activated charcoal or activated carbon is charcoal that has been through an activation process, chemical or physical. Activated charcoal can be made from any substance containing carbon. Given that wood is a renewable raw material, the use of wood as a material manufacture of activated charcoal is recommended. In this study, the material to be used in the manufacture of activated charcoal was wood from the mangrove plant Avicennia marina. The activation process used in this study was chemical activation using ZnCl2. This study included three stages: (1) carbonization; (2) activation of charcoal; (3) adsorption test of activated charcoal. The results showed that the higher the ratio of ZnCl2 mass / charcoal mass used in the activation process, the higher the adsorption capacity of activated charcoal produced. The highest % removal of CH3COOH was obtained at a ratio of ZnCl2 mass/charcoal mass of 2 which was 30.73%.

Biodiesel is a renewable clean bioenergy because it can be produced from vegetable oil. One of the efforts to increase energy independence in the marine sector (blue energy) is to prepare potential alternative fuels derived from microalgae. Microalgae have advantages over other types of plants, because the growth of microalgae is very productive and the growth rate is very fast and does not require fertile land, so it does not compete with food crops. Some microalgae have an oil content of up to 80% of their body mass. Aims to provide information about differences in extraction methods and identification of oil content with microalgae type Chlorella sp. which can be used as raw material for biodiesel. This research method uses FTIR (Fourier Transform Infrared) and GC-MS (Gas Chromatography-Mass Spectrometry) analysis. The results showed that the soxhlet extraction method was able to separate biodiesel and to identify biodiesel raw materials, the percentage of microalgae oil and compound content was obtained. The most dominant compounds are Linoleic Acid compounds, Palmitic Acid compounds, which are dominated by Stearic Acid compounds.
