Abstract: Pangandaran is a district with a coastline of 91 Km, so this district has the potential for coastal tourism that needs to be developed. As a new regency of regional autonomy, demands to carry out construction of facilities and infrastructure to support tourism need to be increased. This study aims to determine the distribution of facilities and infrastructure that need to be developed and to know the factors that influence the determination of the construction of facilities and infrastructure. This research uses qualitative method, data collection is done through literature review and interviews. The results of the study indicate that the factors affecting the distribution of infrastructure include land use, population density, tourism objects, land slope and disaster vulnerability. The analysis shows that the distribution of villages suitable for the development of infrastructure includes the villages of Wonoharjo, Babadan, Pananjang and Pangandaran Village.Keyword: tourism, facilities and infrastructure, thematic maps. Intisari: Pangandaran merupakan kabupaten dengan garis pantai sepanjang 91 Km, sehingga kabupaten ini memiliki potensi pariwisata pantai yang perlu dikembangkan. Sebagai Kabupaten yang baru melakukan otonomi daerah, tuntutan untuk melaksanakan pembangunan sarana dan prasarana guna mendukung pariwisata perlu ditingkatkan. Kajian ini bertujuan untuk untuk mengetahui sebaran sarana dan prasarana yang perlu dikembangkan serta mengetahui faktor-faktor yang mempengaruhi penentuan pembangunan sarana dan prasarana. Penelitian ini menggunakan metode kualitatif, pengumpulan data dilakukan melalui kajian pustaka dan wawancara. Hasil kajian menunjukkan bahwa faktor-faktor yang mempengaruhi sebaran sarana prasarana meliputi penggunaan lahan, kepadatan penduduk, obyek wisata, kemiringan lahan dan kerawanan bencana. Dari hasil analisis menunjukkan bahwa sebaran desa yang sesuai untuk pengembangan sarana prasarana meliputi Desa Wonoharjo, Babadan, Pananjang dan Desa Pangandaran.Kata kunci: pariwisata, sarana dan prasarana, peta tematik.

New Device

The article describes the design of the device for determining the fiber content in individual plants of flax, which is a special torsion scales of the new design. The principle of operation of the device is based on the transformation of the free end of the cantilever-mounted flat spring, to which the object of suspension is suspended, in the rotation of a mirror that reflects the laser diode beam on the scale. The device can be used in fibe flax breeding.

Introduction. Radio Boekoe as a community that affected by the determination of information technology, adapts through the deconstruction process of information dissemination access points by utilizing hybrid media. This study aims to discuss the deconstruction process of information dissemination access points on Radio Boekoe.Research methods. This research used a qualitative method with case study approach. The process of collecting data involved observations, interviews, and documentation studies. The informants are the founder, manager and volunteer of Radio Boekoe.Data Analysis. The research data was analyzed with the stages of reduction, display, and drawing conclusions.Results and Discussion. The deconstruction process of information access points on Radio Boekoe occurred through the use of hybrid media. The deconstruction process of the information access point was expanded to the process of adding information access capacity in the form of Bale Black Box co-working space.Conclusions. The process of deconstruction of information access points on Radio Boekoe occurs through the shifting of local access points in the form of the Gelaran Iboekoe to global hybrid media-based access in the form of internet radio. Furthermore, it is recommended to conduct a research to examine the effectiveness of using hybrid media to expand information access points.

The main purpose of the present study is to assess the usefulness of filter cartridges from end-of-life biological and chemical protection masks, for other applications (with increased added value) instead of landfill deposition. Filters with different ages up to fifty years, were dismantled and divided in their components. Physico-chemical characterisation of each filter cartridge component was performed using different techniques such as: optical microscopy, Fourier transform infrared spectroscopy, pyrolysis, particle size distribution by laser diffraction, surface area determination from the nitrogen adsorption isotherms at 77K, determination of open porosity by helium pycnometry, and dynamic mechanical thermal analysis in the temperature range from -100°C to 200°C. It is shown that the loss of resilience of the rubber sealant is the main factor that controls the shelf life of filter cartridges. On the other hand, most of the charcoal in the activated carbon cloth remains active and can be useful for other less severe applications such as the removal of dissolved components from freshwater and/or marine systems.

Qualitative Analyses

Abstract A quantitative and a qualitative method for the determination of acetone peroxides were subjected to collaborative study. Quantitative analyses are based upon liberation and titration of hydrogen peroxide from acyclic peroxides and hydroperoxides by dilute sulfuric acid and standardized potassium permanganate, respectively. Single determination of 6 samples (varying in per cent levels of peroxide equivalent) each of baking premixes and milling premixes produced very good collaborative results. Qualitative analyses, achieved by comparing infrared spectra of acetone-extracted organic peroxides with acetone-extracted organic peroxides from a reference premix, gave peaks characteristic of the premixes. No interferences were seen from various starch blanks. Both the quantitative and the qualitative methods are recommended for adoption as official, first action.
