Analisis Surface Roughness dan Material Removal Rate pada Proses Sinker-edm Menggunakan Elektroda Graphite

Electrical discharge machining (EDM) is a non-conventional machining process by feeding the workpiece material by means of an electric spark (spark) through the gap between the electrode and the workpiece containing a dielectric fluid. The EDM process is influenced by the material being processed, electrode material, discharge current, spark on time, spark gap, dielectric fluid and so on. The combination of these parameters will produce different machining characteristics. The purpose of this study was to determine the value of the material removal rate and surface roughness of the workpiece (Surface Roughnes), using graphite electrodes and using the Taguchi method to determine the optimal parameters by varying the current parameters 10A, 13A. , 16A, spark on time 210µ, 340µ, 400µ and gap 40, 45, 50

Use of Mung Bean Sprout (Tauge) as Alternative Fungal Growth Medium

Abstract Growth media are essential in mycological studies. Currently, laboratories are using ready-to-use media which are commercially available. However, the prices of such media are high and are a burden on low-funded laboratories. Mung bean sprout (tauge) has been used as a cheap alternative growth medium since 1974, but study comparing performance of the medium with its commercial counterparts has not been reported. This study was done to compare the performances of tauge extract with commercial Potato Extract and Yeast Extract for growing yeast and filamentous fungi. We also endeavoured to optimise the composition of the alternative media by statistical analysis. The results show that the tauge extract medium gave a significantly higher growth rate of Saccharomyces cerevisiae and a significantly lower growth rate of Kluyveromyces marxianus compared to the commercial media. On the other hand, the growth rates of Aspergillus oryzae and Trichoderma viride on all media are not significantly different. The optimum composition of tauge extract media for S. cerevisiae are 9.6 and 6.8 % (w/v) of tauge and sugar, respectively. For A. oryzae, maximum growth is predicted when the medium contains 11.2 and 7.4 % (w/v) of tauge and sugar, respectively.</jats:p

Transcatheter Closure of Perimembranous Ventricular Septal Defect Using the Lifetech Konar-Multi Functional Occluder: Early to Midterm Results of the Indonesian Multicenter Study

Background: The alternative device to close perimembranous ventricular septal defect (pmVSD) has been searched for better result, less complications and applicable for infants. However, the ideal device is still unavailable. We aimed to evaluate the effectiveness and outcome of transcatheter pmVSD closure using the KONAR-multi functional occluder (MFO). Methods: Clinical, procedural, follow-up data of pmVSD patients with symptom of heart failure or evidence of significant left to right shunt, growth failure, recurrent respiratory tract infection, and history of endocarditis who underwent transcatheter closure using the MFO were prospectively evaluated. Results: Between January 2016 and December 2017, there were complete records of 132 pmVSD children closed using MFO from eleven centers in Indonesia. The median of age was 4.5 (0.3-17.4) years; weight 14.8 (3.5-57) kg, defect size at the smallest part 3.4 (1.0-8.1) mm, flow ratio 1.6 (1.3-4.9), mean pulmonary artery pressure 18 (7-79) mmHg, fluoroscopy time 18 (3.8-91) and procedural time 75 (26-290) minutes. A retrograde approach was done in 41 (31%) patients. Procedures succeeded in first attempt in 126 (95.4%), failed in three and migration in three patients. Six of eight infants with congestive heart failure were closed successfully. Of 126 patients with successful VSD closure, 12 months follow-up were completed in all patients. The rate of complete occlusion at 1 month, 3 months, 6 months and 12 months after intervention were 95.2%, 97.6%, 99.2%, and 99.2%, respectively. New-onset aortic regurgitation and moderate tricuspid regurgitation developed only in five and three patients. Neither complete atrioventricular block, nor other complications occurred. Conclusion: Transcatheter closure of pmVSD using the MFO is safe, effective, and feasible in infants and children

Comprehension To Village

It has become very clear, where almost all “village” ontologies emphasize more on the existence of an area / region, as well as the recognition of values inherent in activities, and tend to be made different, especially administratively. We certainly do not deny that administratively the distinction between Village and non-village is needed to facilitate the identification and resolution of problems. But in fact, we find that many villages are more interpreted as something that is not the same as other regions in terms of socio-cultural economic justice and even public policy. So the administrative differentiation then decreases to the distinction between the attitudes of anyone trying to understand the village

Pemahaman Untuk Desa

Menjadi teramat jelas, di mana hampir semua ontologi “desa” menekankan lebih kepada keberadaan satu kawasan/wilayah, serta pengakuan akan nilai-nilai yang melekat pada aktivitas, dan cenderung dibuat berbeda khususnya secara administratif. Kita tentu tidak menolak bahwa secara administrasi kepemerintahan pembedaan antara Desa dengan bukan desa diperlukan untuk mempermudah identifikasi dan penyelesaian masalah. Namun pada faktanya, kita banyak menemukan bahwa desa lebih diartikan sebagai sesuatu yang tidak sama dengan wilayah lain dalam masalah keadilan sosial-budaya ekonomi dan bahkan kebijakan publik. Sehingga pembedaan adimistratif kemudian menurun kepada pembedaan penyikapan-penyikapan siapapun yang mencoba memahami desa
