Media filtrasi merupakan material yang pada saat kondisi operasi sebuah filter memiliki sifat mampu alir terhadap fluida tertentu dan juga memiliki sifat tidak mampu alir terhadat zat-zat pengotor tertentu. Filter tipe Deep-bed filtration memiliki media filtrasi berbentuk padatan granular seperti pasir maupun berupa lapisan serat alam, serat sintetis ataupun serat metal yang dipadatkan. Serat yang digunakan sebagai media filtrasi Deep-bed filtration bekerja dengan prinsip saat fluida mengalir melalui filter maka zat-zat partikulat pengotor tertahan dan terkumpul di sela-sela rongga pori-pori yang terbentuk diantara sekumpulan serat media filtrasi. Jumlah serat yang digunakan per satuan volume atau densitas media filtrasi menentukan nilai tahanan alir atau permeabilitas sebuah media filtrasi. Penelitian ini difokuskan dalam melihat karakteristik permeabilitas media filtrasi serat sabut kelapa berdasarkan jumlah kerapatan serat yang digunakan. Karakteristik permeabilitas media filtrasi sangat berpengaruh terhadap efisiensi aliran fluida dalam aplikasi filter pasir sumur minyak bumi. Karakteristik permeabilitas serat sabut kelapa diukur dengan cara membuat core spesimen uji diameter 3,8 cm, panjang 7 cm dan variasi massa serat sabut kelapa spesimen uji 7,5; 10; 15; 17,5 dan 20 gram. Kemudian masing-masing spesimen uji core diukur nilai permeabilitasnya menggunakan alat Permeability Meter AFS200. Hasil penelitian menunjukkan bahwa nilai permeabilitas serat sabut kelapa menurun seiring bertambahnya massa serat sabut kelapa yang digunakan untuk membuat core spesimen uji. Nilai permeabilitas paling rendah 8508 miliDarcy diperoleh dari spesimen uji dengan massa sabut 20 gram dan nilai permeabilitas paling tinggi 19.790 miliDarcy dihasilkan dari spesimen uji dengan massa sabut 7,5 gram.

Trade is a human effort to meet their needs. However, in trading someone wants instant results and doesn't want to lose, so they do various ways to fulfill their needs, such as using the best selling tattoo with verses from the Koran.

Oleh karena itu, media massa dikatakan tidak netral dan masih menggandeng pihak-pihak tertentu. Informasi tentang Papua masih dibatasi oleh mereka yang memiliki kekuasaan, maka masyarakat Indonesia pada umumnya tidak mengetahui apa yang terjadi di Papua dan sebaliknya, masyarakat Papua tidak mengetahui informasi tentang dunia luar. Penelitian ini akan membahas pemberitaan Tirto.id yang berjudul “Rekaman Kekerasan di Papua”. Penelitian ini dilakukan dengan menggunakan pisau analisis wacana kritis model Teun A. Van Dijk. Metode yang digunakan adalah deskriptif kualitatif. Objek penelitian ini berupa kata, frasa, kalimat atau wacana dalam berita “Rekaman Kekerasan di Papua”. Teknik pengumpulan data menggunakan teknik observasi dan teknik catat. Teknik analisis data menggunakan model Miles dan Huberman. Hasil penelitian ini menunjukkan bahwa analisis struktur teks yang dilakukan pada teks berita “Rekaman Kekerasan di Papua” sesuai dengan tiga struktur model analisis wacana Teun A. Van Dijk.Kata kunci: Analisis Wacana Kritis, Struktur Makro, Struktur Mikro, Struktur Super AbstractThe mass media has a very big role in spreading information and news. However, this mass media can also be used by certain parties to form an understanding or ideology for the public. Therefore, the mass media is said to be not neutral and still takes with certain parties.

This research will discuss the Tirto.id news entitled “Recording Violence in Papua”. This research was conducted using rhe critical discourse analysis knife of the Teun A. Van Dijk model. The method used is descriptive qualitative. The object of this research is a word, phrase, sentence or discourses in the news “Recording Violence in Papua”. The data collection technique used the observation technique and note-taking technique. The data analysis technique used the Miles and Huberman model. The results of this study indicate that the text structure analysis carried out on the news text “Recording Violence in Papua” is in according with the three structures of discourse analysis model Teun A.

Background: Diabetes mellitus (DM) was a condition of insufficient insulin because the pancreas was damaged or insulin could not be used effectively. DM was related to diet. Food for DM patients was important to monitor so the blood sugar would be controlled. Preliminary studies showed that 60% of patients had low levels of dietary compliance. This study aimed to look at the relationship of family support with hospital diet compliance in type 2 DM patients and see the relation between the knowledge levels with hospital diet compliance in type 2 DM patients in Surabaya Haji Hospital. Materials dan Methods: This research was an analytical study with a cross sectional approach. The research variables consisted of family support, the knowledge levels and hospital diet compliance. Respondents were type 2 diabetes mellitus patients in inpatient Hajj Surabaya Hospital with inclusion criteria: 1) without complications of type 2 diabetes mellitus patients; 2) able to communicate well; and 3) willing to become respondents by signing informed consent. Samples were obtained through simple random sampling. Data were analyzed using frequency distribution, cross tabulation, and chi-square statistical test to determine the effect of variables. Result: The results showed that almost all respondents with high family support had high dietary compliance (81.3%), the chi-square test results show that ρ value is 0.004 <α 0.05. That is, there is a relationship between family support and adherence to hospital diet in patients with type 2 diabetes in Surabaya Haji Hospital. The results showed that there were no DM sufferers who had good knowledge about DM patient diet. 75% of respondents with a low level of diet compliance had a low knowledge level, the chi-square test results showed that ρ value was 0.013 < α (0.05), which meant there was a relation between the knowledge level with hospital diet compliance in type 2 DM patients. Conclusion: Family support and knowledge levels about diet regulation would affect the compliance level of the hospital diet to respondents so the health education was needed for families who look after the hospital.
