Bathymetry Mapping Using Landsat 8 Multyspectral Data of Bangsring Coastal Area

The bathymetry map provides information of the seafloor's profile that has diverse in structures, shapes, and topography. Nowadays remote sensing technology becomes more prevalent because it is one of the most effective and efficient methods for bathymetric mapping. This research was aimed to analyze the depth estimation from image processing of Landsat 8 satellite, and measured the water depth using an echosounder. The results showed that the depth of the water in Bangsring was between 0.39 meter and 96.05 meter, and the bathymetric profile continued to decrease with increasing distance. The coefficient determination (R2) and the coefficient correlation (R) were 0.81 and 0.90 respectively with error mean was 19.05%. Based on results, Landsat 8 satellite is suitable and recommended to be used to extract for bathymetric information

LATENT CONFLICT POSSIBILITIES OF MINORITIES UNDER THE SHARIA LAW

Aceh has authoritative legal privilege as it has a special autonomy in implementing sharia as the legal law. In the Islamic tenet, as the foundation of the Islamic law, harmony in society is one of the purposes of implementing sharia. Yet, upon the implementation of sharia in Aceh, several cases of violation interfered with the unity of people with different beliefs in Aceh. This study examined the issue of the scorching church in Singkil to portray intolerance from various perspectives. A qualitative approach utilizing an ethnographic study is implemented with observation and interviews of 25 respondents selected by purposive sampling. The result indicated that misunderstanding led by unharmonious communication and political influence triggered the religious-based conflict in Singkil. Mutual understanding through dialogue and rejuvenating local culture and wisdom are ways to build and maintain harmony among people with different beliefs upon implementing sharia in Aceh.Aceh has authoritative legal privilege as it has a special autonomy in implementing sharia as the legal law.

Operating organic light-emitting diodes imaged by super-resolution spectroscopy

Super-resolution stimulated emission depletion (STED) microscopy is adapted here for materials characterization that would not otherwise be possible. With the example of organic light-emitting diodes (OLEDs), spectral imaging with pixel-by-pixel wavelength discrimination allows us to resolve local-chain environment encoded in the spectral response of the semi-conducting polymer, and correlate chain packing with local electroluminescence by using externally applied current as the excitation source. We observe nanoscopic defects that would be unresolvable by traditional microscopy. They are revealed in electroluminescence maps in operating OLEDs with 50 nm spatial resolution. We find that brightest emission comes from regions with more densely packed chains. Conventional microscopy of an operating OLED would lack the resolution needed to discriminate these features, while traditional methods to resolve nanoscale features generally cannot be performed when the device is operating. This points the way towards real-time analysis of materials design principles in devices as they actually operateope

Distribution and Contamination Status of Heavy Metals in the Surface Sediments along Western Coast of Bali Strait, Banyuwangi

This study attempted to analyze the distribution and contamination status of heavy metals (Cu, Fe and Zn) along western coast of Bali Strait in Banyuwangi, East Java. Bali Strait is one of the many straits in Indonesia with high fisheries activities that could potentially contributed to high heavy metal pollution. There were five sampling areas from the north to south: Pantai Watu Dodol, Pantai Kalipuro, Ketapang Port, Pantai Boom and Muncar as the fish landing area. Heavy metal pollution in these locations comes from many different activities such as tourism, fish capture and fish industry and also domestic activities. Contamination factor (CF), geo-accumulation index (Igeo) and enrichment factor (EF) of each heavy metal were calculated to obtain contamination status of the research area. The concentrations of Fe were observed the highest (1.5-129.9 mg/kg) followed by Zn (13.2-23.5 mg/kg) and Cu (2.2-7.8 mg/kg). The distribution of Cu, Fe and Zn showed variability among the sampling locations in which high concentrations of Cu and Zn were higher in Ketapang Port, whereas high concentration of Fe was high in almost all sampling locations. According to the pollution index, contamination factors of Cu, Fe and Zn were low (CF < 1 and Igeo < 1). However, high index of EF (> 50) showed high influence of the anthropogenic activities to the contribution of the metals to the environment. This could also because of the high background value used in the calculation of the index due to the difficulties in finding background value from the sampling areas.Keywords: heavy metals, pollution index, contamination factor, geo-accumulation index, Bali Strai

A Skill Application Model to Improve Teacher Competence and Professionalism

Teacher professionalism is needed for quality education. The current practice for increasing teacher professionalism is to use skill applications. However, the implementation of skill applications has, in fact, not succeeded in significantly increasing teacher professionalism. This study aims to explain the importance of an effective skill application model coupled with a comprehensive approach to raise the level of teacher competence. This study is qualitative with its data derived from observations, interviews, and questionnaires. The paper's research findings show that existing programs are not sufficiently enhancing teacher competencies and professionalism. Various teacher professional development activities are conducted; however, there has been no continuous post-activity follow-up. These professional development activities tend only to fulfill the administrative requirements for teacher promotion. What is needed is a comprehensive and continuous teacher professionalism assessment model, which is underpinned by a system of mentoring. This study has implications for evaluating the teacher's professional competencies. More comprehensive skill applications need to be formulated as part of an integrated, sustainable, and mentoring [terpadu, sustainable, pendampingan-TSP] approach to develop teacher professionalism significantly
