Over the past few years, as computer acquisition technology has grown, conventional diagnostic medical imaging modalities have increasingly been replaced by digital imagery. Computed radiography (CR) is one of radiographic image acquisition using computers. CR images could be either .jpg files or DICOM files. We exposed some wrenches which diameter of 5.68 mm; 3.99 mm and 3.2 mm as well as a bottle and a circular cork. We use Siemens mobile x-ray to expose the objects and DroidRender 3D DICOM Viewer as the DICOM viewer. We got two images which are .jpg file and DICOM file respectively. We adjust WW and WL parameters in order to optimize the image of the DICOM file. The results are WW = 2833 and WC = 2170.Abstrak: Citra medis yang dihasilkan oleh sistem radiografi pada dasarnya adalah pemetaan dari berkas sinar-X yang diteruskan yang dinyatakan melalui hukum penurunan intensitas sinar-X. Selama beberapa tahun terakhir, dengan semakin berkembangnya teknologi akuisisi komputer, modalitas pencitraan medis diagnostik konvensional semakin digantikan oleh citra digital. Computed radiography (CR) merupakan salah satu teknologi akuisisi komputer pengolah citra radiografi. Hasil citra radiografi pada CR dapat berbentuk file .jpg ataupun DICOM. Untuk membaca file DICOM harus digunakan DICOM viewer yang dapat diunduh secara gratis dari internet.

The purpose of this study are: a) Knowing the mechanism of the Inquiry Method can be used to improve critical thinking skills, b) Knowing the steps of critical thinking, c) Knowing the characteristics of critical thinking, d) Knowing the supporting components of the increasing critical thinking skills by applying inquiry method, and e) Knowing the role of supporting components and their influence in improving critical thinking skills by applying inquiry methods. The results of the study revealed that critical thinking consisted of six sub-abilities which became the core of critical thinking skills, namely interpretation, analysis, evaluation, inference, explanation, and self-regulation. The steps of the Inquiry method are the foundation for critical thinking and can be used as a \"thinking map\". The process of reasoning in a systematic, logical and deep manner accompanied by scientific arguments along with evidence in the form of accurate data/information so that conclusions can be used to train critical thinking. The dominant supporting component that can influence the increase in critical thinking skills using inquiry methods is motivation and learning environment.Abstrak: Penelitian ini mengkaji hal-hal mendasar pada Metode Inkuiri yang dapat digunakan untuk meningkatkan kemampuan berpikir kritis.

Hasil penelitian mengungkapkan bahwa berpikir kritis terdiri dari enam sub-kemampuan yang menjadi inti kemampuan berpikir kritis yaitu interpretasi, analisis, evaluasi, inferensi, eksplanasi dan regulasi diri. Langkah-langkah metode Inkuiri merupakan landasan untuk berpikir kritis dan dapat digunakan sebagai “peta berpikir”. Proses penalaran secara sistematis, logis dan mendalam yang disertai argumentasi ilmiah beserta bukti berupa data/informasi yang akurat sehingga diperoleh kesimpulan yang dapat dipertanggungjawabkan dapat digunakan untuk melatih berpikir kritis.

Regions that have good wind speeds, one of which is West Nusa Tenggara (NTB). West Nusa Tenggara is an area that is crossed by monsunal wind patterns and is an island surrounded by beaches so that the West Nusa Tenggara region receives high winds. This can potentially be installed by wind turbines to be able to convert wind energy into electricity. Wind direction and speed data obtained from satellites are processed into average data then adjusted to the wind speed threshold that can rotate wind turbines. The results obtained are mapped using the GrADS application to determine the potential area for horizontal axis type wind turbine installation at a height of 10 meters based on monsunal pattern direction and wind speed. This study will provide recommendations on potential areas of wind energy and predictions of electrical power that will be generated from the use of these maps. The results of the study show that the West Nusa Tenggara region by utilizing wind energy can create electricity in a year totaling 14067.4026 kWh.Abstrak: Lembaga Penerbangan dan Antariksa Nasional (LAPAN) per 18 Juli 2017 merilis data bahwa dari 166 lokasi yang diteliti, terdapat 35 lokasi yang mempunyai potensi angin yang bagus dengan kecepatan angin diatas 5 meter perdetik pada ketinggian 50 meter. Daerah yang mempunyai kecepatan angin bagus tersebut, salah satunya adalah wilayah Nusa Tenggara Barat (NTB). Nusa Tenggara Barat merupakan wilayah yang dilintasi oleh pola angin monsunal dan merupakan pulau yang dikelilingi oleh pantai sehingga wilayah Nusa Tenggara Barat menerima hembusan angin yang cukup tinggi. Hal ini dapat berpotensi untuk dipasang turbin angin untuk dapat mengkonversi energi angin menjadi energi listrik. Data arah dan kecepatan angin yang diperoleh dari satelit diolah menjadi data rata-rata kemudian disesuaikan ke dalam batas ambang kecepatan angin yang dapat memutar turbin angin. Hasil yang diperoleh tersebut dipetakan dengan menggunakan aplikasi GrADS guna menetukan wilayah yang berpotensi untuk pemasangan turbin angin jenis sumbu horizontal pada ketinggian 10 meter berdasarkan arah dan kecepatan angin pola monsunal.

Area of coral reef in Indonesia known as the “Coral Triangle”. This ecosystem has high ecology and economic value. The existence of the coral reefs is the main attraction for a tourism destination. However, the function and role of these ecosystems are decreasing due to natural factors and artificial factors. One of the natural factors is due to the influence of global warmings, such as sea surface temperature (SST), causing damage and coral death, known as coral bleaching. The purpose of this study was to identify the potential for coral bleaching in Indonesian waters using SPL anomaly analysis obtained from monthly AVHRR POES in the morning and night. This research used hotspots data (HS) by calculating the average of data anomaly difference with a maximum monthly average data during 10 years (2006 - 2017). The results obtained show that areas that have the potential to become coral bleaching in Indonesian waters are quite varied. In general, it covers the northern coast of Banten, DKI Jakarta, West Java, Central Java, East Java, the northwest coast of Lampung, Pekanbaru, and Riau, the northwest coast of Papua Island, and North Natuna waters. The results also showed that sea surface temperatures in Indonesian waters were quite influential on coral bleaching.Abstrak: Indonesia merupakan negara penyumbang terumbu karang terbesar  yaitu 18% dari total dunia. Wilayah terumbu karang di Indonesia dikenal dengan wilayah “Coral Triangle”. Ekosistem ini memiliki nilai ekologis dan ekonomis yang tinggi. Keberadaanya merupakan daya tarik tersendiri untuk dijadikan lokasi wisata. Namun, fungsi dan peranan ekosistem ini menurun akibat faktor alam dan faktor buatan. Salah satu faktor alamnya diakibatkan pengaruh pemanasan global yaitu naiknya suhu permukaan laut (SPL) sehingga menyebabkan kerusakan dan kematian karang atau dikenal sebagai pemutihan karang. Tujuan penelitian ini adalah mengidentifikasi potensi terjadi pemutihan karang di wilayah perairan Indonesia menggunakan analisis anomali SPLyang diperoleh dari POES AVHRR pagi dan malam bulanan. Metode yang diugunakan mencari data hotspot (HS) dengan melakukan  perhitungan rata rata selisih data anomali dengan data rata rata maksimum bulanan selama 10 tahun (2006 - 2017). Hasil yang didapat menunjukkan bahwa wilayah yang berpotensi menjadi pemutihan karang  di perairan Indonesia cukup beravariasi. Secara umum meliputi meliputi pesisir utara dari Provinsi Banten, DKI Jakarta, Jawa Barat, Jawa Tengah, Jawa Timur, pesisir barat laut Lampung ,Pekanbaru dan Riau,  pesisir barat laut dari Pulau Papua, dan perairan Natuna Utara. Hasil penelitian juga menunjukkan bahwa suhu permukaan laut di perairan Indonesia cukup mempengaruhi pemutihan karang.","PeriodicalId":117408,"journal":{"name":"Prosiding SNFA (Seminar Nasional Fisika dan Aplikasinya)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128523581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
