Redesain Gerobak Martabak Menggunakan Antropometri dan Quality Function Deployment

Indonesia has many culinary business using carts, for example martabak. Cart used by the seller martabak is simple cart with stainless steel, aluminum, wood, glass, and made with the approximate size pickup without any consideration of the science. Through anthropometric approach and Quality Function Deployment (QFD), the design of the cart will be good and according to customer needs. Anthropometric approach used to design dimensions of the cart and QFD used to meet consumer needs for design of the cart. Anthropometric data used in the design of the cart are elbow span, fore arm span, high above hand grip, hip height. Consumer needs based on QFD is divided into four. Ergonomics, performance, materials, and designs. The consumer needs come from the questionnaire with consumers and will be processed in a House of Quality (HOQ). Carts design are made to be referring to the anthropometric dimensions and the voice of the customer in QFD. Martabak cart product prices can be determined by using the Cost of Production (HPP). Based on the HPP will know the price cost of sales is the reference price of one the martabak cart

Conductivity and quasinormal modes in holographic theories

We show that in field theories with a holographic dual the retarded Green's function of a conserved current can be represented as a convergent sum over the quasinormal modes. We find that the zero-frequency conductivity is related to the sum over quasinormal modes and their high-frequency asymptotics via a sum rule. We derive the asymptotics of the quasinormal mode frequencies and their residues using the phase-integral (WKB) approach and provide analytic insight into the existing numerical observations concerning the asymptotic behavior of the spectral densities.Comment: 24 pages, 3 figure

RESIKO RADIKALISME MENYASAR KALANGAN REMAJA MELALUI MEDIA SOSIAL

The purpose of this Community Service (PKM) is to train the youth of the Kademangan village as an effort to prevent the entry of elements of radicalism ideology through social media. The use of social media is an activity that is said to be an effort to fill free time for teenagers, the time to use social media access can exceed the usual during the Large-Scale Social Restrictions (PSBB) because social media can be a medium and solution in interactions that become a modern lifestyle. This PKM uses a Mapping scheme for the use of social media, the level of understanding of radicalism, and efforts to socialize youth assistance.

Antioxidant Activity of the Phenolic Leaf Extracts from Monechma ciliatum in Stabilization of Corn Oil

The total phenolic content and the antioxidan potential of methanolic extract (ME), ethyl acetate extract (EAE), and hexane extract (HE) from Monechma ciliatum leaves (MCL) were evaluated. The Folin-Ciocalteu, b-carotene bleaching, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and the accelerated oxidation methods were used for evaluation. Both the extraction yield and the antioxidant activity (AOA) were strongly dependent on the solvent. Among the extracts, ME exhibited highest total phenolic compounds (TPC) and IC50 values for DPPH, followed by EAE and HE, respectively. Peroxide value (PV), anisidine value (AV) conjugated dienes (CD), and thiobarbituric acid reactive substances (TBARS) were taken as the parameters for evaluation of stabilization efficacy of MCL extracts and results revealed MCL to be a potent antioxidant for the stabilization of corn oil. As a general trend, increased AOA was observed for increased extract concentration. The predominant phenolic compounds identified by HPLC-DAD in MCL extracts were p-coumaric acid, vanillin and ferulic acid

Efektivitas Kebijakan Asimilasi Terhadap Narapidana di Tengah Pandemi Covid-19

Penelitian ini membahas tentang Efektivitas Kebijakan Asimilasi Terhadap Narapidana di Tengah Pandemi Covid-19. Adapun yang menjadi pokok permasalahannya yakni bagaimana efektivitas kebijakan asimilasi terhadap narapidana di tengah pandemi Covid-19. Sehingga dari pokok masalah tersebut ditarik sub masalah yaitu 1) Bagaimana pemberian kebijakan asimilasi terhadap narapidana efektif dilakukan di tengah pandemi Covid-19? 2) Faktor-faktor apakah yang menghambat dalam pemberian kebijakan asimilasi narapidana di tengah pandemi Covid-19? Dalam menjawab permasalahan di atas, maka penulis melakukan penelitian yang tergolong penelitian pustaka (library search). Adapun sumber data yang digunakan yaitu sumber data primer yang merupakan dokumen peraturan seperti Peraturan Menteri Hukum Dan Hak Asasi Manusia Republik Indonesia Nomor : M.Hh.01.Pk.05.06 Tahun 2008 Tentang Perubahan Atas Peraturan Menteri Hukum Dan Hak Asasi Manusia Nomor M.01.Pk.04.10 Tahun 2007 Tentang Syarat Dan Tata Cara Pelaksanaan Asimilasi, Pembebasan Bersyarat, Cuti Menjelang Bebas, Dan Cuti Bersyarat, dan Surat Edaran Direktur Jenderal Pemasyarakatan Nomor : E.Pk.04.01-70 Tahun 1994 Syarat Substantif Yang Harus Dipenuhi Oleh Narapidana Yang Mendapat Asimilasi, Pembebasan Bersyarat Dan Cuti Menjelang Bebas yang bersifat mengikat, asli dan ditetapkan oleh pihak yang berwenang, data sekunder berupa pengumpulan data dari bahanbahan kepustakaan. Metode pengumpulan data yang digunakan yaitu cara identifikasi yakni mengelompokkan data atau mencari bahan-bahan kepustakaan yang sesuai dengan judul penelitian. Metode pengolahan dan analisis data yang digunakan yaitu analisis data kualitatif yaitu upaya yang dilakukan dengan cara mengumpulkan data, memilah- milahnya menjadi satuan yang dapat dikelola dan memutuskan apa yang dapat diceritakan kembali dengan data-data yang berasal dari literatur bacaan. Hasil penelitian menunjukkan bahwa (1) pemberian kebijakan asimilasi terhadap narapidana di tengah pandemi covid-19 sangat tidak efektif dikarenakan beberapa faktor diantaranya yang sangat menjadi ketakutan masyarakat yakni mereka dapat mengulang kembali kejahatan yang sama. Di sisi lain, dikhawatirkan narapidana yang bebas asimilasi tidak dapat diterima di lingkungan masyarakat (2) Adapun hambatan yang terjadi pada saat pemberian kebijakan asimilasi terhadap narapidana yakni mereka tidak tahu apa yang akan mereka lakukan jika bebas dari penjara dan juga lingkungan sosial yang tidak mendukung dengan kehadiran mereka. Adapun implikasi dalam penelitian ini yaitu 1) masyarakat juga ikut berkontribusi dengan bisa menerima narapidana yang telah bebas asimilasi di lingkungan sosial. 2) pihak aparat pun harus memberikan pemahaman kepada masyarakat tentang kebijakan asimilasi terhadap narapidana sehingga masyarakat memahami dan bisa menerima narapidana bebas asimilasi di lingkungan mereka. Sebab terjadinya kejahatan yang sama dilakukan oleh narapidana asimilasi disebabkan oleh masyarakat yang mengucilkan mereka salah satunya yaitu tidak mudah memberikan pekerjaan kepada narapidana tersebut

In vivo functional neurochemistry of human cortical cholinergic function during visuospatial attention

Cortical acetylcholine is involved in key cognitive processes such as visuospatial attention. Dysfunction in the cholinergic system has been described in a number of neuropsychiatric disorders. Levels of brain acetylcholine can be pharmacologically manipulated, but it is not possible to directly measure it in vivo in humans. However, key parts of its biochemical cascade in neural tissue, such as choline, can be measured using magnetic resonance spectroscopy (MRS). There is evidence that levels of choline may be an indirect but proportional measure of acetylcholine availability in brain tissue. In this study, we measured relative choline levels in the parietal cortex using functional (event-related) MRS (fMRS) during performance of a visuospatial attention task, with a modelling approach verified using simulated data. We describe a task-driven interaction effect on choline concentration, specifically driven by contralateral attention shifts. Our results suggest that choline MRS has the potential to serve as a proxy of brain acetylcholine function in humans

Vancomycin sensitivity of Staphylococcus aureus isolates from hospital patients in Karachi, Pakistan

Methicillin-resistant Staphylococcus aureus (S. aureus) (MRSA), resistant to all antibiotics including Vancomycin, has been reported in Japan, USA, Canada and Brazil. Hence, the main objective of this study was to evaluate the possible presence of Vancomycin resistant or intermediate S.aureus in Karachi. A total of 850 clinical isolates were collected from two civil hospitals in the city between February 2006 and January 2007. They were identified using standard bacteriological methods.Sensitivity to recommended antibiotics was determined by disc diffusion, agar dilution, and E-test quantitative minimum inhibitory concentration (MIC). Susceptibility to natural or semi-natural products was determined by the agar dilution method. Out of 850 isolates, 250 were MRSA, of which 22% were resistant to 4 µg/ml Vancomycin, 24% to 8 µg/ml, 15.2% to 16 µg/ml, 10% to 20 µg/ml, and 13.2% to 30 µg/ml; the remaining 15.6% were sensitive to all used concentrations. Although we did not detect any Vancomycin-resistant S. aureus (VRSA), we found that 13% of the strains were intermediates (VISA), i.e. resistant to 30 µg/ml of Vancomycin. Because of the continuously increasing prevalence of VISA, it is imperative to minimize the use of Vancomycin. Indeed, the drug should only be prescribed for the treatment of documented, culture-proven infections with MRSA that are not susceptible to routine or alternative agents. This should help avoid the consequences of the development of Vancomycin resistant S. aureus (VRSA) in our environment
