Abstract

Macroalgae is one of the marine biological resources that has a potential to be utilized further by humans. This research aims to study macroalgae diversity and utilization potency by humans in the coastal area of Tunda Island. The study was conducted at 4 stations using the belt transect method. Results of this study indicated that there were 15 species of macroalgae found that came from 3 macroalgae classes, they were chlorophyceae, phaeophyceae, and rhodophycea. Macroalgae species that are often found are Padina minor, Halimeda macroloba, and Gracilaria salicornia. The highest macroalgae diversity was found at station 3 with a value of 2.44. Based on the type of macroalgae found in the field there are several macroalgae species that can be utilized, and the lack of information causes the low macroalgae utilization by the local community.

Abstract

Salvinia molesta is an aquatic weed having very high growth rate. The high abundance of this species biomass could be utilized as a source of alternative energy. This research was aimed to utilize S. molesta as a substrate for biogas production using batch system in order to reduce euthrofication effect in a lake. Cow manure was used as starter for anaerobic process because containing bacteria. Proximate test was conducted to analyze the chemical characteristics of the aquatic weed. Chemical oxygen demand, total solid, and total volatile suspended solid of weed and manure were analyzed according to the APHA 2012 method. Biogas composition was analyzed with gas chromatography. The results showed that the S. molesta contained high lignin content and low C:N ratio. Hydrolisis and acidification process occured very rapid, resulting in an increase of the weed and manure mixture COD. In the other hand, the decreased of COD removal was caused by the massal death of methanogenesis bacteria. The total solid and total volatile suspended solid content were not significantly decreased. Potential biogas production from S. molesta was 58.16 L.kg-1 with 318.29 mL.gram VS-1day-1 of methane production. This production value was still low or compared to that of cow manure which have been established as biogass materials and need modification to improve the biogas production.

Abstract

The existence of reef fish is certainly closely related to the existence of reefs coral because the ecosystem is a habitat for reef fish. Coral reefs are ecosystems that are commonly found on small islands in the tropics including the Seribu Islands. The Seribu Islands are a group of 110 islands located off the coast of Jakarta and up to 80 kilometers north of the Java Sea. In this study, we examined the species distribution and diversity of reef fish species on two different distance location in Jakarta Bay using environmental DNA (eDNA) metabarcoding analysis from two sites which are Untung Jawa Island and Harapan Island. The 4L eDNA seawater samples were collected at a depth of 8-9 meters at each site and then analysis using specific primer (MiFish U) of 12S rRNA. Overall, the higher species richness was found on Harapan Island (52 species) followed by Untung Jawa Island (11 species). The Shannon-Wiener Index also showed Harapan Island has higher reef fish diversity based on three taxonomic level (family, genus, and species). There were only five mutual reef fish species found in the two locations, namely Atherinomorus aetholepis, Auxis thazard, Cephalopholis sexmaculata, Epinephelus chlorostigma, and Plectropomus areolatus. The results of these findings in this current study are in line with anthropogenic pressure different where Untung Jawa Island is the closer one to Jakarta Bay than the Harapan Island that located relatively far from Jakarta Bay.

Abstract

There are many species of macroalga grow in marine ecosystem and potentially as raw material for bioethanol resource. Bioethanol is a conversion result of carbohydrate, one of macroalgae biomass content. The exploration of macroalgae require information about  growth rate ability to determine availability in the nature. This research analyze growth rate and carbohydrate content of marine macroalga Gelidium latifolium on cultivation using varied injection of carbon dioxide and aeration. The treatments were control (K), 2000 cc CO2 injection and aeration (P1), 3000 cc CO2 injection and aeration (P2), 2000 cc CO2 injection without aeration (P3), and 3000 cc CO2 injection without aeration (P4). Samples weight were 3 gram in early cultivation on laboratorium scale for 42 days observation. The results showed that the daily growth rate Gelidium latifolium during the study ranged from 0.02-1.06%. The highest daily growth rate was 1.06±0.14% (P2). Carbohydrate yield was 18.23% in early cultivation then 19.40% (K and P2), 20.40% (P1), 16.87% (K3), and 16.40% (P4) after cultivation. The high of carbohydrates value may not guarantee the sustainable Gelidium latifolium biomass utilization as raw material for bioethanol production because of the low growth rate, thus it is necessary to modified and encourage cultivation method effectively.

Abstract

Kondisi oseanografi dan pemilihan lokasi adalah faktor penting dalam keberhasilan dan keberlanjutan kegiatan budidaya lobster laut menggunakan sistem keramba jaring apung. Salah satu kendala budidaya lobster adalah belum adanya aturan khusus mengenai kriteria kesesuaian lokasi budidaya. Tujuan dari penelitian ini adalah untuk menentukan kriteria dan lokasi yang sesuai untuk budidaya lobster di sekitar perairan Teluk Pidada. Dasar kriteria yang digunakan adalah kesesuaian kondisi oseanografi dan kualitas air laut terhadap konstruksi keramba jaring apung dan habitat alamiah lobster. Metode analisis spasial menggunakan sistem informasi geografi dengan sistem pembobotan digunakan dalam penentuan lokasi yang sesuai untuk budidaya, yang mencakup kecerahan, kekeruhan, TSS, klorofil-a, DO, nitrat, fosfat, amonia, pH, TOM, dan salinitas. Hasil penelitian menunjukkan bahwa 9 dari 15 parameter memiliki kondisi yang sangat sesuai. Hasil studi analisis kesesuaian wilayah memperlihatkan bahwa 78,8% perairan atau seluas 2.890,8 ha dalam kategori sangat sesuai, kemudian hanya 21,2% perairan atau seluas 755,2 ha yang tergolong sesuai, dan tidak ditemukan kategori tidak sesuai di perairan Teluk Pidada. Hampir sebagian besar wilayah teluk sesuai untuk budidaya lobster, namun sebagian titik berlokasi agak menjauh dari daratan karena tingginya nutrien dan run-off kurang sesuai untuk kegiatan budidaya.

Abstract

Lampung Bay is an important water crossing in South Sumatra that is greatly influence by anthropogenic activities and oceanographic characteristics. This study characterized and estimated the spatial and temporal Primary Productivity (PP) in the three sections of the bay: head, middle, and mouth. The PP was modeled by using Sea Surface Temperature (SST), chlorophyll-a, Primary Productivity, and Photosynthetically Active Radiation (PAR) collected from remote sensing data and field measurements. Primary productivity was modeled with a Vertically Generalized Production Model (VGPM), and data validation was done using the Root Mean Square Error method. The distribution of PAR in Lampung Bay ranged from 35–52.50 E/m2/day. The distribution of SST ranged from 28.5–31.50°C. The highest distribution of chlorophyll-a was at the hHead of the bay with a range of 0.30-12 mg/m3. Correlation analysis shows that chlorophyll-a had the highest influence on PP (R2=0.99). While the middle and outer areas of the bay have a low average with values of 122.65 and 101.84 gC/m2/year. Our models show that there is high primary production at the Head of the bay, reaching eutrophic and mesotrophic levels. The middle and outer areas of the bay show productivity levels corresponding to mesotrophic and oligotrophic levels.

Abstract

The mangrove ecosystem is a coastal ecosystem that is important for humans. Mangroves absorb carbon in the atmosphere and store it in biomass or sediment. So, in other words, mangroves play a significant role in mitigating global climate change. This study aimed to examine the structure of the mangrove ecosystem composition and estimate standing carbon stocks on Sangiang Island, Banten. The data taken was for the categories of trees, saplings, and seedlings (consisting of mangrove species, DBH, and height). The study was conducted at three stations with three replications for each station. The allometric formula obtained the estimated carbon stock from the stand biomass value. The results showed that 11 species of mangrove species were found with an average density of 1266 ind/ha (trees), 3733 ind/ha (saplings), and <70% (seedlings). Then the estimated average carbon stock in Sangiang Island, Banten is 271.29 tons/ha.
