Indonesia is a maritime country with two of the three area consists of sea with a very favorable potential of the Indonesian economy. However. many thefts occur in marine fish Indonesia. Each year, the state must lose up to 11.8 trillion as a result of illegal fishing in the Arafura Sea. he Government has attempted to reduce losses due to illegal fishing by deploying surveillance vessels to conduct surveillance, but the ship still has limitations on deadlines related to logistics and fuel oil. Therefore, research must be done to develop a system of unmanned ship for patrol boats to patrol autonomously without the use of fuel oil. The system consists of hardware and software. The hardware consists of sensors such as GPS and compass as a navigational reference, Sonar sensor for obstacle avoidance, ATMega 2560 as a microcontroller and motor driver as the actuator. The software is built using C with Arduino IDE compatible with AVR microcontroller. The system will read the GPS coordinates and compass direction in order to run unmanned. The system is also equipped with a transmitter to control the system manually. The results show the system is able to move the ship to navigate automatically. The system able to read the GPS coordinates and the reading direction of the compass well. The system also able to avoid obstacles that are in front of the system. The system is also able to be manually controlled and can transmit serial data to identify the condition of the system.

Illegal fishing carried out by foreign fishing vessels (Kapal Ikan Asing, KIA) and Indonesian fishing vessels (Kapal Ikan Indonesia, KII) in Indonesian waters also causes other crimes such as the entry of illegal immigrants to Indonesia. This writing aims to assess the relationship between illegal fishing and the entry of illegal immigrants as a form of transnational crime. The research method used is normative legal research. The sources of legal material used are primary, secondary and tertiary legal materials related to writing. The technique of collecting data through library studies and analyzed qualitatively. The results of the study show that Indonesia as the largest archipelagic country in the world with 17,504 large and small islands and a length of coastline of 81,700 km 2 makes Indonesia a country with abundant marine resource potential. For this reason, many foreign naval fleets have made Indonesian waters as the main destination for their capture fisheries. This capture fishery company has more foreign ownership, the exploitation of marine resources that we own both legally and illegally. Likewise, this also happened in the Moluccas territory. As a province of the archipelago with an ocean area of ​​658,295 km 2 with a coastline length of 11,000 km 2, the Maluku Sea holds abundant potential for marine wealth. Arafura Sea is one of the fisheries management areas which is often the main destination for foreign-owned fishing vessels. These fresh fish from the Moluccas are stolen and taken away in fresh condition directly to the area of ​​origin of the perpetrators. Illegal fishing activities not only make Indonesia economically disadvantaged, but there is another problem, namely the existence of other crimes that usually follow the illegal fishing activities. One of them is the entry of illegal immigrants into Indonesian territory.

This paper briefly describes the past development of the shrimp fishery in the Arafura Sea, including intensity of illegal fishing, and presents the impact of increasing fishing pressure on the quantity of catch and biomass. The maximum sustainable yield and the optimum fishing effort are estimated.

High Spatial Resolution Imaging

We have used high spatial resolution imaging secondary ion mass spectrometry (SIMS) to differentiate mineralogical phases and to investigate chemical segregations in fluidized catalytic cracking (FCC) catalyst particles. The oil industry relies on heterogeneous catalysis using these catalysts to convert heavy hydrocarbon fractions into high quality gasoline and fuel oil components. Catalyst performance is strongly influenced by catalyst microstructure and composition, with different chemical reactions occurring at specific types of sites within the particle. The zeolitic portions of the particle, where the majority of the oil conversion occurs, can be clearly distinguished from the surrounding silica-alumina matrix in analytical SIMS images.The University of Chicago scanning ion microprobe (SIM) employed in this study has been described previously. For these analyses, the instrument was operated with a 40 keV, 10 pA Ga+ primary ion probe focused to a 30 nm FWHM spot. Elemental SIMS maps were obtained from 10×10 μm2 areas in times not exceeding 524s.

The Right

Spanish and English speakers tend to conceptualize time as running from left to right along a mental line. Previous research suggests that this representational strategy arises from the participants’ exposure to a left-to-right writing system. However, direct evidence supporting this assertion suffers from several limitations and relies only on the visual modality. This study subjected to a direct test the reading hypothesis using an auditory task. Participants from two groups (Spanish and Hebrew) differing in the directionality of their orthographic system had to discriminate temporal reference (past or future) of verbs and adverbs (referring to either past or future) auditorily presented to either the left or right ear by pressing a left or a right key. Spanish participants were faster responding to past words with the left hand and to future words with the right hand, whereas Hebrew participants showed the opposite pattern. Our results demonstrate that the left-right mapping of time is not restricted to the visual modality and that the direction of reading accounts for the preferred directionality of the mental time line. These results are discussed in the context of a possible mechanism underlying the effects of reading direction on highly abstract conceptual representations.
