Published: October 2019

Abstract
The increase in CO2 in the air has caused global warming, the impact of which is felt by everyone in the world. One way to control climate change is to reduce greenhouse gas emissions by maintaining the integrity of natural forests and increasing the density of trees outside the forest. Mangrove forests have a role as absorbers of CO2 from the air, and save more carbon than most tropical rainforests. The purpose of this study was to determine the biomass, stock carbon and CO2 uptake of mangrove Sonneratia alba in the Passo coastal waters, Inner Ambon Bay. Sampling of mangrove S. albaby belt transect method with a belt width of 10 m. Data collected included the number of trees, diameter (DBH) and area of observation. Biomass analysis and carbon content of S. albatrees were carried out in a nondestructive way (without damaging plants), which was using biomass estimation allometric equations. Carbon (CO2) uptakein S. alba is 564.48 tons.ha−1 which is stored on above of the ground at 111.50 tons.ha−1 and below the ground at 42.31 tons.ha−1. Total stock carbon of 153.81 tons.ha−1 were converted from total biomass of 327.26 tons.ha−1. High carbon sequestration and storage is supported by high biomass and high biomass is supported by a high number and diameter of trees.

Authors: Rahmawati S , Irawan A 
Published: October 2019

Abstract
Seagrass bed is one of important ecosystems usually located adjacent to coral reefs and serves several important ecological roles such as feeding and nursery ground for several marine biotas. Physically, seagrass bed protects the reef from inland sedimentation. The status of seagrass beds, therefore, becomes an important thing in protecting the coral reef ecosystem. The study was conducted on July 2018 with the objective to analyze the current status of seagrass bed at Coral Reef Rehabilitation and Management Program (COREMAP) site in Ternate Island. Ten stations were chosen for this study and linear transect method was used to analyze species composition and canopy coverage. The result showed that there are 8 species found in this area with 5-7 species commonly found at each station. Among 8 species found, Thalassia hemprichii being the most common species inhabiting all of the sites. Average canopy coverage in seven stations was below 59.9% which considered as less healthy, whilst at other three locations was below 29.9% which considered as poor status. Overall, the status of seagrass beds in this area is less healthy with moderate canopy cover. This status has remained the same since 2015 to the present time.

Abstract
Sea turtles are one of those protected animals according to government regulation no. 7 1999. Living turtle migrates along area the Pacific Ocean, the Indian Ocean, and Southeast Asia Ocean including Sea of Halmahera. In Indonesia, there are 6 species of 7 species of sea turtle in the world and 3 of them are in The Meti Island namely the green sea turtles (Chelonian mydas), hawksbill sea turtle (Eretmochelys imbricata) and olive ridley sea turtle (Lepidocheys olivacea). All species of sea turtles in Indonesia categorized as a protected animal, but until now the exploitation of sea turtle still widely practiced by the community of The Meti Island. The objective of this study, therefore, was to analyze the knowledge and community understanding of existence and the utilization of the sea turtle. The data was taken through observation of sea turtle existence and interview with The Meti Island community. The result showed as 68.15 % of respondents knows about the existence of sea turtle, 37.5 % know about the impact of utilization to its sustainability but 43 % still harvesting and using sea turtle as a consumption and trade. This shows the lack of awareness in the community about the sustainability of sea turtle around The Meti Island. The high level of utilization of sea turtle shows the weakness of the function in the monitoring and supervision by the regional government against the utilization of an animal that should have to be protected.

Data analysis on sea water quality data in Jakarta Bay using Principal Components Analysis (PCA) method during transitional monsoon 2012
Authors: Martina A , Radjawane I M 
Published: October 2019

Abstract
To get a conclusion from a data matrix consisting of 3 individuals and 2 variables is relatively easy. However, it is very difficult to understand the large amount of data. Therefore, it requires data analysis methods for an easier representation. Based on sea water quality data in Jakarta Bay from BPLHD DKI Jakarta (Jakarta Environmental Management Board), there are 24 biological, physical, and chemical parameters in 23 stations. Based on the quality and quantitative of data, we use only one set data on October 2012 as representative of the Second Transition monsoon. Analysing was conducted for 10 parameters namely turbidity, total suspended solid (TSS), temperature, pH, salinity, dissolved oxygen (DO), biological oxygen demand (BOD), methylene blue active substances, phenol, and zinc (Zn) at 23 stations. Consequently, in this paper, we get a conclusion from the data using principal component analysis (PCA) method for its application in data analysis. The method of PCA is used to analyse the data matrix from a similarity point of view between stations and correlation between parameters. The result of PCA is four principal components i.e. PC 1 (27.73% of the variance) is mainly related to TSS, temperature, salinity, and DO. PC 2 (16.33% of the variance) is mainly related to BOD. PC 3 (12.39% of variance) is mainly related to MBAS, phenol, and zinc. PC 4 explains 11.09% of variances related mainly to turbidity.
Response of upwelling variability to the local and remote forcing in the Banda Sea
Authors: Rachmayani R , Ningsih N S , Februarianto M , Abdullah F A R 
Published: October 2019

Abstract
The Banda Sea experiences a strong upwelling between April and November associated with the seasonal strengthening of the trade winds. Data of surface wind, sea surface temperature (SST) and salinity in the period of 1990-2008 were used to further study the response of upwelling to the local and remote forcing in the Banda Sea. A local forcing (Ekman Pumping) during Southeast Monsoon plays role in contributing the upwelling intensity indicated by shallower thermocline and colder SST. In addition, this study exhibits that the upwelling strength is controlled remotely by El Ñino Southern Oscillation (ENSO) where during El Niño (La Niña) periods in Southeast Monsoon, the upwelling weakens (strengthens) in the Banda Sea.
Variability of sea surface topography in coastal area (study case: Indonesia)

Abstract
The deviation of the sea surface from the geoid reference surface is known as the Sea Surafce Topography (SST). SST is caused by several physical phenomena such as ocean wave, tides, current and atmospheric pressure loading, and the main application of SST is to determine ocean circulation. To get the SST, we use Sea Surface Height (SSH) and Mean Dynamic Topography (MDT) based on 30 years of sea-level data derived from multi-mission of satellite Altimetry and geoid height (Undulation) from Global Gravitation Model EGM-2008. Indonesia is an archipelagic country in the equatorial region that lies between Indian and Pacific oceans. Its geographical setting will affect variability of Sea Surface Topography (SST) in the Indonesian Sea. The anomaly from SST is one of the oceanic parameters that play a crucial role in the ocean dynamic and its possible hazards. We found that the characteristics differ considerably from one place to another, depending on the bathymetric depth and type of sea. The mean SSH varies from about 40 meters and rises to the east up to a height of 80 meters. Likewise, the MDT value increased from 0.5 meters to the east to a height of 1.2 meters. In closed, narrow and shallow seas, the long time-series of those surfaces are less sensitive to the effects of El Niño and La Niña as well as global sea level rise. On the other hand, global sea level rise significantly affects the characteristic of both surfaces over open and deep seas. We hope by using more spatially dense data from multi-mission satellite altimetry, we can see more detail about the local phenomena that influence SST. By studying the variability of SST from more than one cycle (18.6 years) it is expected that it can be used to understand the dynamics of the coastal area in Indonesia.

Published: October 2019

Abstract
Ship engine power is estimated at initial design process to satisfy the required speed. This ship parameter is determined by computation of ship resistance and propulsion parameter from any existing methods or executing ship model test. In fact, the results of ship model tests do not satisfy those of the existing methods. However, for initial design approach this may be used to estimate the engine power. This approach is used in design process for many ships but some methods are not suitable for certain type of ships. Three type of ships were developed and evaluated to prove this issue. They were fishing ship, passenger-cargo coaster and semi-displacement ship. The resistance and propulsion parameters of those ships were determined by the existing methods. Three models of those ships were tested in the towing tank to validate the results of the resistance from existing methods. The results of computation and model test were presented and analyzed. It was found that there were difference between the results of computations and those from model tests for three ships. Some recommendations were stated at this paper concerning the application of the results for such ships.
Prevalence of hypertension and efforts to develop a monitoring system for hypertension in community living in the coastal areas of Noloth and Itawaka Village, Saparua Island, Central Maluku District
Authors: Que B J , Ihalauw C Y , de Lima F 
Published: October 2019

Abstract
Hypertension is a chronic medical condition due to the increased blood pressure. Uncontrolled hypertension might cause several complications, including stroke, heart and kidney disease. More complex problems for patients and families emerge when complications occur. The 2014 Health Profile of Maluku Province reported that the prevalence of hypertension in population aged 18 years or above was 457,152 people and only 50.74% had their blood pressure measured. This prevalence rate was low compared to the prevalence reported by The 2013 Basic Health Research (Riskesdas). The low prevalence rate was due to the shortage of facilities and medical personnel to conduct hypertension examinations, in addition to the low motivation of the community to have a regular blood pressure check. In 2014, the number of non-communicable diseases in Central Maluku was considered high but the incidence rate of hypertension was low. However, most of the non-communicable diseases were associated with hypertension. This study was aimed to develop a monitoring system in dealing with hypertension patients of Itawaka and Nolloth village. From secondary data obtained in 2015, there were 4.2% of 8.660 individuals from East Saparua who suffer from hypertension. It was also found that regular checkup of patients and their compliance on taking hypertension drug was low. We propose a monitoring mechanism as follows: screening patients with hypertension, mapping their location, develop patient forms on application in smartphone, filling out patients’ record according to their residence, assigning health workers responsible in the specified area and on a weekly basis monitor blood pressure and their compliance with taking anti hypertensive drugs.
Hybrid solar-wind-diesel power plant for small islands in Maluku Province
Authors: Pelupessy D , Manuhutu F 
Published: October 2019

Abstract
Maluku Province is an archipelagic province consist of 1,340 islands mostly classified as small island and has the total area of 712,479.69 km2 of which 658,331.52 km2 (92.4%) are marine and only 54.15 km2 (7.6%) are terrestrial. This geographic condition causes high insularity and approximately 34% of villages in Maluku are without electricity and it is highly impossible to provide every remote small island with the power supply. Solar and wind penetration into existing diesel systems can be considered as a breakthrough to meet the need for power supply for these remote islands. A techno-economic analysis is applied to perform a design of an optimal hybrid solar-wind-diesel power plant to serve the load of the villages at these remote islands. The hybrid plant can reduce cost about 20% as well decrease of greenhouse gas emissions of diesel generator alone. Based on the result obtained, the villages in Maluku Province particularly those at the remote area are the potential candidate for deployment of the proposed hybrid solar wind-diesel power plant for electricity generation.

Abstract
Lermatang Village is situated at Southwest Maluku Regency and is known as a producer of seaweed. Generally, the seaweed produced in this village belongs to Eucheuma cottonii, which is a source of carrageenan and has high economic value. Carrageenan is known as raw material for the pharmaceutical, cosmetic, food and other industries, as gelling agents, material binders, emulsifiers, and stabilizers. The most common problem faced by the seaweed grower was they haven’t been able in optimizing the processing technologies yet. The seaweed farmer is still selling the seaweeds in form of dry seaweed without further processing and this cause a low price. The aim of this research was to study the physicochemical properties of carrageenan of Eucheuma cottonii originated from Lermatang Village fo Southwest Maluku Regency. Seaweed was extracted by using sodium hydroxide then physicochemical properties of carrageenan were observed. The results showed that physicochemical properties of carrageenan were indicated by yield 34.50 – 44.25 g, gel strength 500 - 850 g/cm2, viscosity 35.2- 40.89 cP, water content 14.32-25.73%, ash content 21.34-22.62% and sulphate content 14.85-16.50%.

Published: October 2019

Abstract
Fish is very perishable, soon after caught and death, deterioration took place quickly especially in a high-temperature environment. Quality control is a necessity to keep the freshness of fish and the prime nutritional quality. In this study interview and observation were done on the focus group to investigate quality control activities carried out by the artisanal fisher community. In many places in Maluku, small pelagic fish caught by using purse seine net. The fishing ground is relatively close to the landing site at the coastal area and landed in 1-2 hours after death. Shortly after landed ice treating is applied on the fishes with the ratio of ice to fish roughly 1:2 and also a small amount of clean sea water added onto the fish-ice mixture in order to chilling fish and keep it fresh. Most fish are transported to the central market in town by using cars which takes one to two hours, and the rest taken by the small retailers and distribute to the closest markets in the village. If lots of fish harvested, some retailers will sell it on foot from house to house. The small-scale fishermen and retailers know very well the necessity of maintaining the freshness of fish, so it will be in good quality when delivered the consumer hands and the high price.

Published: October 2019

Abstract
Dried anchovy is a prospecting product from Buru Island Maluku which is produced traditionally by spreading on the ground under the sun with a used net as a base. Effort to develop that method is needed to meet the increasingly stringent standard of sanitation and hygiene food products, especially for modern and export markets. Three types of solar drying equipment as the traditional method development were applied to produce dried anchovy and the product characteristic was investigated. The two enclosed solar dryers walled and roofed using plastic with multilevel racks and drying space forms a tunnel dryer system. One of them using transparent plastic and another using blue plastic. The third equipment is “para-para” (local called for bamboo or wood arranged side by side horizontally with an altitude roughly 1.25 meter above the ground) roofed using blue tarpaulin plastic. The characteristics of dried anchovy produced by using solar dryer equipment are better than traditional drying method product, especially organoleptic, insoluble acid ash content and total bacterial. Dried anchovy with the better quality characteristic will be reach the wider distribution and higher segment market.
