Pengaruh Polutan Taklarut terhadap Ketahanan Isolator (Studi Kasus Pltu Molotabu)

Penelitian ini bertujuan untuk memperoleh informai mengenai tegangan lewat denyar dan arus bocor yang diakibatkan oleh iklim serta polusi pembakaran batu bara yang menyebabkan adanya pelapisan polutan dipermukaan isolator. Metoda pemberian lapisan polutan pada permukaan isolator dengan cara menyemprotkan polutan pada permukaan isolator dengan beberapa kondisi pengujian. Metode pegujianya dengan cara diberikan tegangan tinggi sampai terjadi tegangan lewat denyar. Data hasil pengukuran memperlihatkan bahwa, terdapat hubungan yang signifikan antara polutan yang dilapisi pada permukaan isolator dan ESDD yang melekat pada permukaan isolator. Hasil penelitian dapat disimpulkan bahwa dari beberapa kondisi pengujian, maka pada kondisi kering takberpolutan nilai tegangan lewat denyar paling tinggi dan pada kondisi basah perpolutan nilai tegangan lewat denyar paling renda

Acupressure and Aromatic Ginger Herb for a Migraine

Background: a Migraine is a headache with pain attacks lasting 4 - 72 hours. Pain is usually unilateral, it is pulsating, the intensity of pain is moderate to severe and aggravated by activity, and can be accompanied by nausea, vomiting, photophobia, and phonophobia. Headaches are one of the most common disorders of the nervous system. It has been estimated that 47% of the adult population experience headaches at least once in the past year in general. According to TCM, headache is a disease with a headache accompanied by a variety of symptoms, where the cause is an external pathogen and causes in the body. Acupressure is one form of traditional treatment skills by suppressing acupuncture points with emphasis on using fingers or blunt objects on the surface of the body, in order to support promotive, effective, rehabilitative efforts. In addition to acupressure, herbal drinks can also be used to reduce pain, namely aromatic ginger. Purpose: Knowing the effect of acupressure and aromatic ginger herbs (Kaempferia galangal Linn.) combination therapy in reducing migraine complaints. Methods: Acupressure at Fengchi point (GB20) 50 times, Taiyang (EX-HN5) 50 times, Sanyinjiao (SP6) 30 times, Taichong (LR3) 50 times and aromatic ginger herbs (Kaempferia galangal Linn.) 15 grams for 28 days. Results: Migraine complaints decreased from 5 times a month to 3 times a month. No more complaints of nausea, hypochondrium pain, diarrhea, and insomnia. Conclusion: Acupressure at Fengchi point (GB20) was 50 times of the pressure, Taiyang (EX-HN5) was 50 times of the pressure, Sanyinjiao (SP6) was 30 times of the pressure, Taichong (LR3) was 50 times of the pressure and the aromatic ginger herbs (Kaempferia galangal Linn.) As much as 15 grams for 28 days could reduce migraine complaints

The Multiplicity of M-Dwarfs in Young Moving Groups

We image 104 newly identified low-mass (mostly M-dwarf) pre-main sequence members of nearby young moving groups with Magellan Adaptive Optics (MagAO) and identify 27 binaries with instantaneous projected separation as small as 40 mas. 15 were previously unknown. The total number of multiple systems in this sample including spectroscopic and visual binaries from the literature is 36, giving a raw multiplicity rate of at least $35^{+5}_{-4}\%$ for this population. In the separation range of roughly 1 - 300 AU in which infrared AO imaging is most sensitive, the raw multiplicity rate is at least $24^{+5}_{-4}\%$ for binaries resolved by the MagAO infrared camera (Clio). The M-star sub-sample of 87 stars yields a raw multiplicity of at least $30^{+5}_{-4}\%$ over all separations, $21^{+5}_{-4}\%$ for secondary companions resolved by Clio from 1 to 300 AU ($23^{+5}_{-4}\%$ for all known binaries in this separation range). A combined analysis with binaries discovered by the Search for Associations Containing Young stars shows that multiplicity fraction as a function of mass and age over the range of 0.2 to 1.2 $M_\odot$ and 10 - 200 Myr appears to be linearly flat in both parameters and across YMGs. This suggests that multiplicity rates are largely set by 100 Myr without appreciable evolution thereafter. After bias corrections are applied, the multiplicity fraction of low-mass YMG members ($< 0.6 M_\odot$) is in excess of the field.Comment: 25 page

Imaging protoplanets: observing transition disks with non-redundant masking

Transition disks, protoplanetary disks with inner clearings, are promising objects in which to directly image forming planets. The high contrast imaging technique of non-redundant masking is well posed to detect planetary mass companions at several to tens of AU in nearby transition disks. We present non-redundant masking observations of the T Cha and LkCa 15 transition disks, both of which host posited sub-stellar mass companions. However, due to a loss of information intrinsic to the technique, observations of extended sources (e.g. scattered light from disks) can be misinterpreted as moving companions. We discuss tests to distinguish between these two scenarios, with applications to the T Cha and LkCa 15 observations. We argue that a static, forward-scattering disk can explain the T Cha data, while LkCa 15 is best explained by multiple orbiting companions.Comment: SPIE conference proceedin

Biometric Identification and Authentication Providence using Fingerprint for Cloud Data Access

The raise in the recent security incidents of cloud computing and its challenges is to secure the data. To solve this problem, the integration of mobile with cloud computing, Mobile biometric authentication in cloud computing is presented in this paper. To enhance the security, the biometric authentication is being used, since the Mobile cloud computing is popular among the mobile user. This paper examines how the mobile cloud computing (MCC) is used in security issue with finger biometric authentication model. Through this fingerprint biometric, the secret code is generated by entropy value. This enables the person to request for accessing the data in the desk computer. When the person requests the access to the authorized user through Bluetooth in mobile, the Authorized user sends the permit access through fingerprint secret code. Finally this fingerprint is verified with the database in the Desk computer. If it is matched, then the computer can be accessed by the requested person
