Instrumen Lagrangian telah banyak digunakan untuk pengumpulan data arus laut dan observasi di perairan Indonesia membutuhkan data yang langsung dapat diketahui (real time). Kajian ini menekankan pada pengembangan GPS Drifter Combined (GERNED) dari sisi desain dan sistem pengukuran. Hasil pengujian menunjukkan bahwa GERNED dapat digunakan di danau, perairan dangkal, dan laut terbuka. Konstruksi terdiri dari bahan akrilik, Polyethylene, dan aluminium. Desain konstruksi terdiri dari bagian atas sebagai penutup dan juga tempat sensor udara dan lampu indikator, bagian tengah yang merupakan pusat mikro-kontroller, catu daya, sensor-sensor, penyimpanan data manual dan pengiriman data via satelit. Biaya yang dibutuhkan untuk membuat alat ini sekitar 15.000.000 (lima belas juta rupiah) dengan biaya terbesar adalah kontrol pengiriman data. Pada bagian bawah merupakan baling-baling statik. Pengujian yang dilakukan di laboratorium untuk melihat posisi lokasi sudah menunjukkan data yang sama dengan data lapangan sedangkan untuk pengujian lapangan yang dilakukan di pulau Untung Jawa menunjukkan bahwa arah dan pergerakan GERNED sama dengan pergerakan float tracking umumnya.

Understanding the physio-chemical oceanic and atmospheric processes is critical in monitoring climate change. Archipelagic and Small Island countries are vulnerable to the detrimental effects of climate change, and open access oceanic databases can solve data limitations leading to further development of action plans and government policies. A website was developed (www.isea-podc.org) to distribute and augment free oceanographic data based on various in-situ sampling instruments. Oceanographers review the data collected and stored in the portal. It is led by the Marine Research Laboratory (MEAL), Padjadjaran University, in partnership with Marine Science Institute (MSI), University of the Philippines. This framework supplements information that can support marine ecosystems, fisheries, and climate science studies. Furthermore, all data are accessible to not only the academe but also decision-makers in all aspects. The data sources are student research and the new instruments (RHEA and ARHEA) developed by MEAL. In the future, the portal will be integrated with other government institutional data to provide other functional features and can yield network-wide analyses. In the next phase, collaboration from ASEAN countries should be conducted to gain more impact and provide robust datasets.

This study aims to examine the pattern of microplastic waste movement of Pacific Garbage Patch (PGP) that has the potential to enter the north of Indonesia sea. This study very important because microplastic affected the regional tourism activities, water pollution, and economics of fisherman and local society. The impact is very widerange to local and national economics. The method used is a simulation and descriptive analysis. The simulation method used is hydrodynamic simulation and trajectory of particles conducted for 365 days in 2016. The study areas in this study include eastern Indonesia, the Philippines, and the Pacific Ocean. The data used are wind, tidal, bathymetry, microplastic weight, and microplastic flux. The simulation results show the movement of microplastic at point source 1 tends to the northeast with a clockwise circular motion. The simulation results at source point 2 indicate that the microplastic movement tends to revolve around the source point in a clockwise circular motion. The result of simulation of source point 3 shows that the microplastic movement tends to the north with the circular motion and left-right movement. The displacement of microplastic particles within a year is only 0.11 - 8.94 km from the source point. This study showed that within a year, microplastic waste from PGP does not have the potential to enter the waters of Indonesia.

Morotai Island is developing district located in the North of North Halmahera and one of the areas that has potential source from ecosystem biodiversity. This biodiversity is very unique related to ocean condition such as ocean currents and other properties. This research used survey data in 2015 and other data from satellite and database insitu. The results showed that the Sea Surface Temperature (SST) ranges from 26.7 0C to 32.8 0C and the salinity ranges from 33.48 to 36.8 psu characterized by open ocean. The ocean currents patterns different in surrounding area due to variety of depth, tide effect, monsoonal situation, and local aspects. The mangrove area mostly located in the south, while coral reef stands in the almost coastal area. This region is mostly influenced by monsoons and also the Indonesia throughflow. From the results, the location in the southern part is very suitable for marine culture and tourism, while in the northern region it is very suitable for tourism, conservancy, and fishing. These activities will lead Morotai as an important area for enhancing the local revenue

Seagrasses are an essential component of the coastal environment with provide many ecosystem services beneficial to humans. Understanding the pattern of dispersal of segrasses is important for conservation management. The aimed of this research was to analyze the seed dispersal of the seagrass Enhalus acoroides in the Marine Protected Area of Biawak Islands, Indramayu, based on hydrodynamic modelling. Oceanographic data were downloaded from several open acces website and location of seagrasses based one insitu observation. Then, oceanographic parameters and seed traits were used to develop the particle trajectory model. Our analysis showed that the seafloor’s depth around the islands varied, ranging from 8 m to 48 m. The seed dispersal was strongly influenced by alternating tidal currents (reversing current). The particle trajectory showed that most of the seeds would be transported outward away from each source in the islands, and they settled in deeper areas further from the coast of the islands. This result indicates that the seagrass population in Biawak Islands might depend predominantly on vegetative recruitment, which is slow. This may be related to the low seagrass canopy cover in Biawak Islands.

Abstract. At present, marine debris is an important issue in Indonesia. Due to the complex pattern of ocean currents, research on the distribution of marine waste in Indonesia is still very lacking. This study aims to determine the movement of microplastic particles at the Savu Sea National Marine Park. The method used was to simulate the hydrodynamic model and particle trajectory. Data used were wind, tides, bathymetry, coastline, weight of garbage, and garbage fluxes. Analysis was carried out on physical data visualization, hydrodynamic models, and particle trajectory models. The hydrodynamic model simulation shows if the average current velocity ranges from 0,0002 m/s to 0.35 m/s. The particle trajectory showed that microplastic particle movements tend to move to the south, where some of them move west and east of the Savu Sea. Besides being affected by tides, microplastic particle movements in the Savu Sea National Marine Park are also influenced by various currents that pass through the Savu Sea waters, especially by Indonesia Troughflow.Keywords: ocean model, particle pathways, microdebris, Savu Seas, Indonesia Troughflow Abstrak. Saat ini, sampah laut merupakan salah satu isu kemaritiman di Indonesia. Karena pola pergerakan arus yang kompleks, penelitian mengenai distribusi sampah laut di Indonesia masih sangat kurang.

Oil bodies play an important role in storing energy in plants and animals. The structure of oil bodies consists of triacylglycerol surrounded by a layer of phospholipids and bound by unique proteins. Oil bodies are widely found in various organisms such as algae, soil plant, water seeds plants, flowers, pollen, and animals. Mangrove seeds, also known as "bakau" plants, are a unique aquatic plant that can grow in water bodies throughout the world, including Indonesia, which has a high oil content of 40-70%. Mangrove seeds are a potential alternative biomass that can be used for biodiesel material. Therefore, the aim of this community service is to provide education on the oil bodies found in mangroves and the conservation of mangrove seeds, in the form of mangrove mitigation on Pramuka Island. This outreach program can provide knowledge to the community, particularly mangrove farmers on Pramuka Island, on how to utilize mangrove seeds as alternative food and biofuel sources to improve their future economic income. This outreach program also educates the local community to preserve the mangrove seeds for their sustainability in the future.
