Abstract

Indonesia is maritime country surrounding by Wide Ocean. Two seasons that always happened in this area have been influence to the situation of oceanography and fisheries zone. The seasons which happened because influence by wind of monsoon, which are West Monsoon, East Monsoon, and the transition condition among both. The fishing ground information used Geography Information System (GIS) and remote sensing (RS) software and can be used for specific purpose. The most fundamental application is for dynamics population and distribution of fish in the ocean ecosystem. Environmental characteristics such as: temperature, thermo clines, salinity, ocean currents, and depth is identify potential fishing use technology of image satellite represent the way of identifying indirectly. From satellite data far identified by interconnected oceanography parameters sliver with fish habitation or potential schooling fish. Between oceanography parameter having relation with life of pelagic fish is water temperature go out to sea and fertility of territorial water area. Map of conducive satellite data, sea surface temperature ( SST) and content of chlorophyll-a the can be obtained by information about oceanography phenomena specially front thermal and upwelling representing potency area as fishing indicator. Fishing vessel usually leave fishing base without exactly knowing location of fishing ground so it always stay in uncertainty potential location of fishing ground, therefore its haul also becoming not surely. Meanwhile, in consequence of uncertainty fishing location, resulted fishing ship passing many time and fuel to looking for location of fishing ground. Successfully of the fishing operation is not depend by experience of fishing master but there are must be have the data where fishing ground located. And application of semi active fishing gear much help fisherman salary and require following by other sub-province especially at the west season, but having to limit by usage mesh size enabled by law or regulation so that small fish do not follow to be caught.

Abstract

The problems which arise in every rainy season in Singaraja are flood and the back up of water. They are caused by the inability of totally functioning drainage system. The lack of awareness and participation of the society in maintaining the drainage system nearby causes clogging in the drainage system caused by industrial garbage or those come from houses. This research is aimed at knowing the suibility of the debit capacity of drainage system and the factors causing flood in drainage system III in Singaraja city. The reason why the analysis of flood was conducted is because flood often appears in this location, and in this city there are also : (1) area of water source called Mumbul (source of fresh water or municipal waterworks). If the flood flows into this area, it will be worrying that the water will be polluted and the water pump will be broken, (2) market, (3) shopping area, and (4) housing. This research was conducted since March until June 2008 at drainage system III in Singaraja city around Tasbih street, Anggrek street, Leli street, Kenanga street, Flamboyan street, Tukad Mumbul, and A.Yani street. To know the debit capacity of the drainage system (Qs) and factors causing flood in drainage system III in Singaraja city, the analysis using mathematical model was conducted, in this case drainage dimension, debit surface running of water (Qp), and flood debit (Qb) were used as the input. Meanwhile, the factors influencing why the society threw garbage into the drainage were analyzed based on the descriptive method. The result of the research shows that the capacity the debit at Tasbih street, Leli street, Anggrek street, A. Yani Street, Flamboyan street, as well as Tukad Mumbul have been over the capacity, while the capacity of drainage debit at Anggrek and Kenanga Street have matched with planned condition (environment condition), with the Qs=74,66 m3/second; Qp=115,68 m3/second; Qb=6,79 m3/second. From the mathematical model analysis we got contribution of debit caused by change of environment (Ql)=45,27 m3/second and the debit caused by social behavior (Qm)=6,35 m3/second. The act of society that brings effect to flood is the act of throwing garbage in disposal area and this causes the increase of water debit until 3,37 m3/second; keeping the garbage in an empty place causes the increase of 0,56 m3/second; and directly throwing garbage into the drainage (upper course) causes the increase of 2,25 m3/second. Factors affecting society throwing garbage into drainage are : lack of disposal area, no punishment for those who break the rule (28,57%), the society’s view on dirty place of drainage system (71,43%) and the permissive society to the rule of throwing garbage (71,43%).

Abstract

Jakarta Bay lies in the north of Jakarta and receives freshwater run off from thirteen rivers that run through the Jakarta metropolitan area, a conurbation that is home to some 20 millions people. Total discharges of organic water pollution have experienced a rapid increase from 214 tones per day in 1980 to over 537 tones per day in 1993. This is resulted to the high nutrient levels and eutrophication of coastal waters. Input pollutant in Jakarta Bay change the natural environment condition. Eutrophication has severe local impacts in the Jakarta Bay (GEF, 2008). Study of TSM in Jakarta Bay was conducted during September 2008 to June 2009. The aims of this research were to investigate the transportations of TSM in Jakarta Bay MODIS satellite data was used and the current pattern circulation in Jakarta Bay. Methods applied were MODIS satellite data analyses from 2003 to 2005 and numerical model 2-dimensional, for the in-situ data of total suspended matter secondary data from LIPI in September 2004 was applied. To validate the result regression method was used. Validation research results using MODIS satellite analysis showed the regression coefficient is R=0.72. Vector of current in Jakarta Bay in September 2004 experienced of the change direction and speed at each condition during spring condition at flood tide 1.23 m/s, highest tide 0.77 m/s, ebb tide 0.83 m/s, and lowest tide1.31 m/s and during neap condition at flood tide 0.71 m/s, highest tide 0.69 m/s, ebb tide 0.90 m/s, and lowest tide 0.34 m/s. Transportation of TSM in Jakarta Bay are dynamic, in dry season transportation of TSM higher than rain season.

Abstract

The process of urbanization has changed the face of the landscape, not only in urban environments, but it also has expanded the areas around it. The changes in land use are increasing not only occurs in areas formerly categorized a semi-intensive, such as agricultural lands, but also in extensive and protection areas. However, in some periphery still characterizes the function of a good environment; especially in rural areas the changes that occurred were limited to their own needs (subsistence), as in Mount Walat, Sukabumi. This study aims to identify and analyze the tropical agro-forestry efforts and to provide landscape ecological pattern in order to preserve the environment and social culture. The method used in this study was a site survey method with focusing on the biophysical condition of the site and analysis of reports or other sources regarding the management processes undertaken. Mount Walat ± 359 Ha area of forest is guided by land use pattern that is divided into four characters, i.e., forest ecosystem, opened forest, ownership land, and countrified. Its area of ± 70 Ha was managed as agro-forestry land. The form of tropical agro-forestry in the country side around the site consists of yard and mixture garden, while in the arable land is a mixture garden. In order to prevent of destruction, then the manager invites Hegarmanah villagers to cooperate in maintaining its sustainability by allowing land to cultivated in Mount Walat agro-forestry, with the terms agreed by both parties, without damaging the forest ecosystem. The study was suggested that the community structures and developmental pathways which arised across a gradient of disturbance frequencies can provide models for alternative agro-forestry solutions. Addressing multiple objectives and sustainability in a complex biophysical and socioeconomic system ought to be a challenging and exciting enterprises.

Abstract

Sedimentation is one of coastal dynamic processes. Sedimentation in the mud volcano of Porong at Sidoarjo is an important phenomena to be known as a reference to find out a good solution in the tragedy of mud volcano eruption. Observation of the sedimentation process in the mud volcano eruption of Porong Sidoarjo needs in situ data and data processing technique to know of more details about sedimentation process and the main cause of the sedimentation and the large mud volcano eruption. Therefore, studying of sedimentation process needs the quick timing and high accuracy method. One of the technique which can be used is remote sensing method compared with numerical model and in situ data oservation. Study area is in the Regency of Porong Sidoarjo Province of East Java on August 2008 in position of 7°30’ S - 7°40’ S and 112° 30’ E - 113°30’ E. The aim of this study is to know the pattern of TSM distribution from satellite image using the algorithm which was introduced by Zhou and Kutser. The pattern of TSM from the Landsat and Modis satellite images show that the TSM distribution from the porong river, will then accumulate to the estuary. But, the concentration will decrease in the area that is far from the estuary. This is caused by the influence of the tide current in the Madura strait.From the simulation model was shown that the sediment distribution is influenced by pattern of current generated by tide. High tide where the current move to the upstream sediment in the porong estuary, the sediment was then accumulated in the estuary area. However, at low tide where the current move to the downstream, sediment transportation will move out from the estuary at the maximum level. The pattern of current shows that the moving is to the south direction in the porong coastal that will cause the sediment concentration that out from the porong estuary willgo to to the south direction. The water flow in front of the mouth of porong estuary maybe one of the cause why the sediment distribution tend to move to the south direction.

Abstract

The exploitation and management of water resource be more beneficial, if preceded by study which includes biological aspect besides physics and chemical parameter of waters. The biological aspects study can be conducted by monitoring the change of ecosystem (biomonitoring). One of study that entangles biomonitoring is the research concerning change of marine plants. Marine plants consists of seagrasses and seaweeds. Using ALOS/AVNIR-2 data in this research because it has 3 visible bands (blue, green, and red) with 10 meter spacial resolutions can penetrate into water column. Aims of research were (1) to know combinations of bands in ALOS/AVNIR-2 data was better in Lyzenga method applying to mapping marine plants, (2) to know the general species of marine plants in north coastal area of Sumbawa regency. Lyzenga method was used in image processing process to know the combination of bands which have better for mapping marine plants. Preliminary steps of image processing were image cropping, geometric correction and radiometric correction. Water column effect was reduced by Lyzenga algorithm. Six classes were determined by multispectral classification process i.e. seagrass, seaweeds, coral, hard sand and rubble of coral, and substratum. Field surveys has done to identify the accuracy level. The accuracy method by Lillesand and Kiefer (1990) was used in this research.The result of accuracy test show for image band 1 and band 2 combination given better visual object benthic than another combinations of bands, with overall accuracy was 86.67%. Seagrass found in north coastal area of Sumbawa regency consist of four species there were Cymodocea rotundata, Enhalus acoroides, Syringodium isoetifolium, and Halophila ovalis with width equal to 835.37 ha, while seaweeds were found equal to five species there were Euchema cottoni, Euchema cottoni ssp sakul, Halimeda sp, Padina sp, and Sargasum duplicatum with width equal to 269,16 ha.
