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

PEMBUATAN APLIKASI UNTUK PERENCANAAN TRAYEK ANGKUTAN KOTA DI KOTA MOJOKERTO

So far the process of public transportation route planning in Mojokerto City government doesn't integrated Some of process doing manually and other process has been Ilse supporting application, not special application that use for public transportation route planning. So we need an application of public transportation route planning and the proses has integrated on other application, so user didn't need to process separately. This research related to build an application of public transportation route planning based of transportation knowledge This application able to receive the data input of citizen. the data of region, the data of toad network, traject Bata and the data of home interview survey done by the Dinas Perhuhungan Mojokerlo.. Then process all input with four Step Transportation Planning Model ", include travelling generator. route distribution. route decision caul model decision. And we get new route and its evaluation, such as route lime ratio, route cost ratio, prosentase of use public transportation. and pangsa pasar for old route and new route this year and so on. Finally we get which route is better for every route public transportation

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

Changes and Existence of Cirebon's Rivers in 1900-1942

Pada masa Hindu-Budha hingga VOC peran sungai sangat penting, karena sungai merupakan jalan raya utama yang mudah ditemui dan dibutuhkan oleh masyarakat Cirebon sebagai alat transportasi untuk menghubungkan kawasan pantai (pelabuhan) dengan interior (pedalaman). Namun, pada masa Hindia Belanda keberadaan sungai di Kota Cirebon telah berubah. Perubahan keberadaan sungai adalah hal yang mendasar. Pertama, seiring dengan perkembangan zaman dan teknologi serta meningkatnya kebutuhan barang dan jasa terus berlanjut untuk kebutuhan eksploitasi daerah jajahan, serta untuk mengefisienkan pendistribusian barang dan jasa. Kemudian, pemerintah Hindia-Belanda melakukan peralihan dari moda transportasi sungai ke berbagai moda pembangunan transportasi darat, seperti jalan raya dan kereta api. Kedua, kondisi ekologi sungai yang tidak sehat turut memengaruhi, sehingga banyak orang yang sering terkena imbasnya oleh wabah penyakit akibat kondisi sungai yang tidak sehat dan ketika musim hujan tiba, sungai meluap dan menggenangi rumah penduduk. Faktor-faktor tersebut yang melatarbelakangi pemerintah Hindia-Belanda melakukan perubahan terhadap keberadaan sungai-sungai di Kota Cirebon, seperti pengerukan Sungai Lama "Kali Bacin", normalisasi Sungai Sukalila, normalisasi Sungai Sipadu dan pembuatan drainase

Effect of Indoor Environment on Occupant Air Comfort and Productivity in Office Buildings: A Response Surface Analysis Approach

Indoor air quality is a significant factor influencing occupant comfort, health and productivity. Indoor air comfort and its relationship to occupant comfort and productivity are widely documented. Statistical correlation between the two has been highlighted in scientific literature. This paper investigates any unique correlations between non-air quality parameters (such as lux level, temperature, and noise level) and indoor air comfort and presents a study investigating the effect of indoor environmental quality on occupant air comfort and productivity. This study was conducted by collecting data on indoor environmental parameters using remote sensors and an online survey for occupant responses for twelve months. Data analysis was performed using Response Surface Analysis to present mathematical relationships between indoor environmental quality parameters and occupant air comfort. Results show that carbon dioxide up to 600 ppm, VOC up to 25% (by volume) and humidity up to 60% have a positive impact on occupant air comfort and productivity. Our research highlighted that some non-air quality parameters, such as outdoor temperature and lux levels, affect occupant air comfort. These results would enable built environment professionals to design and operate offices (subtropical desert climate) conducive to occupant comfort and productivity
