Abstract

This research was done on March-April 2014 at village of Akudiomi that was wellknown as Kwatisore in Nabire Regency at Papua Province. The research aimed to determine species composition, length-weigh relationship, local fishermen inventarization and mapping lobster fishing ground. Method used was descriptive with observation techniqu, sampling and interview. Also, the mapping and identification the correlation between physical oceanography parameters (temperature, salinity, depth and pH) on the fishing ground of lobster was to know the effect on the lobster availability. Resuls showed that during field observation, three species of lobsters were caught by fisheremen in Akudiomi that are P. versicolor for 111 individu, P. longipes and Thenus spp was 1 individu consecutively. The prediction of lobster growth pattern only done for P. versicolor as the dominant species caught in Akudiomi, that P. versicolor’ carapace length 8-13 and weight 250-1,097 gr/individu. Correlation between carapace length and weight of P.versicolor indicated positive with the same direction at 0.8636, (near 1). Analysis growth pattern P. versicolor showed , thus means or allometric negative (the growth of length faster than weight). Regression analysis indicated that temperature, depth, salinity and pH significantly affected the yield of lobster caught by fishermen in Akudiomi. Morevoer, oseanography aspects that had significant effect to caught of lobster temperature, salinity and pH.

Abstract

Tidal waters are very important for port interests, sea transportation, fisheries industry, coastal engineering and coastal area mitigation. Tidal height formed is a superposition of tidal amplitude due to the gravitational pull of the sun, moon and earth. The Tidal components are K1, O1, P1, S2, M2, K2, M4, MS4. This study aims to determine the components and types of tides in the shipping channel of Manokwari-West Papua using the admiralty method. Formzahl 0.732 number means the type of tidal that is formed is mixed tide prevailing semidiurnal, two high and low tide, two high and one low tide or two times low tide one high tide in a day. Mean Sea Level (MSL) was caused by water conditions, coastlines and bathymetry, the gravitational forces of the moon and sun. The MSL was obtained 98 cm. large tidal range occurs during full moon conditions and low tides occur during perbani (1.62-2.44 m). The amplitude Mean High Water Level level reaches 279 cm and Mean Low Water Level reaches -83 cm.

Abstract

The construction of bridges and the Trans Papua Mameh-Bintuni road section of West Papua Province crosses rivers (Mothy-I Bridge), (Mothy-II Bridge), and (Yuki-II Bridge). The impact of this development is estimated to affect a decrease in river water quality and pollution. River water quality criteria are determined based on the pollution indicator. Water quality samples were taken from rivers directly affected by bridge construction activities and the Trans Papua Mameh-Bintuni road preservation. Water quality parameters and river water sampling refer to SNI 6989.57:2008. Water sampling was carried out after the construction activities were completed. The results showed that the water quality in the three rivers met the class II river water quality standards according to Government Regulation No. 22 of 2021. The Pollution Index of rivers (Mothy-I Bridge), rivers (Mothy II Bridge), and rivers (Yuki Bridge II) each has a Pollution Index value of 0.769; 0.816; and 0.770. This value describes the water quality in the three rivers in the excellent category, qualify environmental quality standards. Biological, chemical and physical indicators are in the natural concentration value, thus the bridge construction activities and the preservation of the Mameh-Bintuni road in West Papua Province that have been carried out do not have a negative impact on changes in river water quality.

Abstract

The rise of global surface temperature is predicted to increase the rainfall and runoff. Long-term changes in rainfall will affect the water resource, thus also influencing the fisheries and maritime sector. Understanding the global climate change and their effects, especially in Indonesia as one of the environmental condition parameters, is a part of the strategy for mitigation and adaptation towards climate change, and it is important to do early to support the sustainable development of Indonesia. Magicc-Scengen v5.3 is one of the widely-used climate models. Magicc is used in the projection of sea level and temperature, while Scengen is used to produce the regional climate change scenario with the resolution of 2.5°×2.5° latitude and longitude. This study aims to determine the climate change level especially the air temperature and rainfall in Indonesia using Magicc-Scengen model (global circulation model UKHADCM3 and UKHADGEM) using A1-BAIM and B2-MES scenarios. According to the Magicc-Scengen simulation model, in the year 2100, the global temperature will change from 2.5°C (B2-MES) towards 3°C (A1-BAIM). In Indonesia, the maximum change of temperature will occur on the A1-BAIM scenario, which is 2.12°C, distributed across Sumatra and Kalimantan. Moreover, on B2-MES scenario, the maximum temperature change is 1.88°C. The simulation results also show a rainfall escalation, from 25.4 towards 26.2%, in March-April-May (MAM) period. The A1-BAIM scenario determines that the highest rainfall will occur in MAM (for the year of 2050 and 2100), while B2-MES scenario determines that the rainfall pattern varies widely, in which the highest of it in 2050 will occur on December-January-February (DJF). However, for the year 2100, the highest rainfall will occur on MAM.
