No full textPada suatu sistem distribusi tenaga listrik, tingkat keandalan merupakan hal yang sangat penting karena untuk menjamin kontinuitas suplai tenaga listrik kepada konsumen. Keandalan sistem distribusi merupakan tingkat keberhasilan suatu sistem untuk periode waktu yang ditentukan dan dibawah kondisi operasi yang telah ditentukan, dalam pengertian ini tidak hanya kemungkinan kegagalan tetapi juga besarnya durasi dan frekuensi itu penting. Indeks keandalan pada dasarnya adalah suatu angka atau parameter yang menunjukan tingkat pelayanan serta tingkat keandalan dari suplai tenaga listrik sampai kepada konsumen. Indeks-indeks keandalan yang sering dipakai dalam suatu sistem distribusi adalah SAIFI (System Average Interruption Frequency Index), SAIDI (System Average Interruption Duration Index) dan CAIDI (Customer Average Interruption Duration Index). Setelah melakukan pengambilan data, penulis membuat one line diagram penyulang BDKR menggunakan aplikasi ETAP 16.0.0 lalu menjalankan simulasi model reliability assesment dan perhitungan manual sehingga mendapatkan hasil indeks keandalan penyulang BDKR. Hasil simulasi diaplikasi ETAP 16.0.0 pada penyulang BDKR mendapatkan nilai indeks keandalan sistem ditribusi SAIFI 1.33 kali/pelanggan/tahun, SAIDI 8.62 jam/pelanggan/tahun, dan CAIDI 6.48 jam/frekuensi/tahun. Dan hasil perhitungan manual mendapatkan nilai indeks keandalan sistem distribusi SAIFI 1.14 kali/pelanggan/tahun, SAIDI 8.34 jam/pelanggan/tahun, dan CAIDI 7.31 jam/frekuensi/tahun.

In a power distribution system, the level of reliability is very important because it is to ensure the continuity of electricity supply to consumers. The reliability of a distribution system is the success rate of a system for a specified period of time and under predetermined operating conditions, in this sense not only the possibility of failure but also the magnitude of duration and frequency are important. The reliability index is basically a number or parameter that shows the level of service and the level of reliability from the supply of electricity to the consumer. Reliability indices that are often used in a distribution system are SAIFI (System Average Interruption Frequency Index), SAIDI (System Average Interruption Duration Index) and CAIDI (Customer Average Interruption Duration Index). After taking data, the author makes one line diagram of BDKR feeder using the ETAP 16.0.0 application and then runs a simulation model of reliability assessment and manual calculation so that it gets the reliability index results of the BDKR feeder. The simulation results applied by ETAP 16.0.0 on BDKR feeders get the SAIFI distribution index value of 1.33 times / customer / year, SAIDI 8.62 hours / customer / year, and CAIDI 6.48 hours / frequency / year. And the results of manual calculations get the reliability index value of the SAIFI distribution system 1.14 times / customer / year, SAIDI 8.34 hours / customer / year, and CAIDI 7.31 hours / frequency / year

Selecting Hormonal Contraceptives in Women Taking Antiepileptic Drugs : Review of Literature and Practical Recommendations
No full textContraception is a very important issue in women with epilepsy, since very broad questions taken in applying it to prevent unplanned pregnancy. The choice of contraceptive methods must be related to how the mechanism of action of antiepileptic drugs (AEDs), the contraceptive itself, and both interactions. Hormonal contraception can induce metabolism of AEDs and lead to increasing of seizure frequency, and in the other hand AEDs may decrease the blood levels of hormonal contraception. Therefore, physician must consider the type of contraception being used before prescribing AEDs. Additionally, they should emphasize the interaction between them in counseling, to assure that women with epilepsy have time to decide which type will be best use for them. This challenging matter needs better recommendation for practice, both neurologist and gynecologist.

Premature Ovarian Failure and Epilepsy
No full textPremature ovarian failure (POF) or premature menopause refers to development of amenorrhoea due to cessation of ovarian function before the age of 40 years. The diagnosis is based on elevated FSH levels in menopausal range (usually above 40 IU/l) detected on at least two occasions a few weeks apart. The term “epilepsy†defines a group of disorders characterized by an enduring predisposition of the brain to produce seizures. The hypothalamic-pituitary-ovarian axis regulation is affected by the abnormal neurophysiology of seizures, and the hypothalamic-pituitary-ovarian associated hormones are affected by medications used to treat seizures in women with epilepsy. Ictal and interictal discharges can disrupt the normal activity of brain structures, including the limbic system, amygdala, hypothalamus, and pituitary gland. Management of epilepsy in women requires not only knowledge of epilepsy, but also recognition of the various roles and priorities women have in their lives (education, career development, child rearing, the role as carer within the extended family), and attention to gender-specific issues and their impact on patients’ wellbeing throughout life.

Nudging Green Preferences: Evidence from a Laboratory Experiment
No full textEnvironmental degradation has been one of the major global concerns in the last few decades. Efforts are made to improve our environment including how to alter consumers' preferences toward the use of environmental-friendly products. We conduct an online laboratory experiment to investigate the effectiveness of information and nudges regarding green products using social (cultural) identity-specific campaigns. Our study shows that information and green nudges are unable to alter subjects' risk aversion and time preference. However, green nudges are effective to motivate subjects to allocate more to green product and that differs the effectiveness between information and green nudges in our context. Lastly, we find that some green perceptions are associated with subjects' willingness to pay for green products and characteristics. We conclude with a discussion of how to effectively deliver nudges in promoting green consumption

An experiment on bribery, tenure duration, and punishment severity in the Indonesian public finance context
No full textAgainst the backdrop of increasing concern over corruption, this study delves into a laboratory experiment investigating the intricate dynamics of bribery concerning the duration of official tenures and the efficacy of punitive measures. Experimental methods prove pivotal in unraveling the complexities inherent in corrupt behaviors. The study unfolds a compelling pattern, shedding light on the interplay between public officials and civilians, particularly emphasizing the impact of officials' tenure duration on bribery. It brings forth a crucial correlation between familiarity with officials and a heightened likelihood of bribery, with extended tenures amplifying this susceptibility. The concept of "fixed pairing" accentuates the role of prolonged official incumbency in influencing bribery tendencies. Additionally, introducing punitive measures with financial repercussions proves effective in curbing bribery incidents and associated givebacks, particularly when applied to bribe recipients, suggesting heightened stakes public officials face. The study demonstrates the potential of dual treatments involving random pairings and punitive approaches to reduce the magnitude of bribes and givebacks. This study underscores the necessity of curtailing prolonged official tenures to mitigate bribery tendencies, offering insights into enhanced governance and ethical conduct through strategic rotational shifts and robust penalties. These comprehensive findings contribute valuable perspectives to addressing corruption and enhancing ethical standards within public institutions

Hydrogenolysis of furfuryl alcohol to 1,2-pentanediol catalyzed by first row transition metal salts
No full textThe growing and relatively large market share of 1,2-pentanediol (1,2-PeD) has attracted attention of researchers to find effective and economically viable catalysts. One type of catalyst that can be used for synthesizing this compound is transition-metal-based catalysts, employed in the hydrogenolysis of furfuryl alcohol (FOL). In this study, the hydrogenolysis of furfuryl alcohol were performed with 2-propanol as the hydrogen source and transition metal salts as the catalysts. The used catalysts include first-row early and late transition metals, i.e., ZrOCl2·8H2O, VOSO4·H2O, FeSO4·7H2O, CuSO4·5H2O, NiCl2, Al(NO3)3·H2O, CoCl2, FeCl3·6H2O, and Zn(NO3)2·6H2O. It was found that ZrOCl2·8H2O, VOSO4·H2O, and FeCl3·6H2O demonstrated superior catalytic activity compared to the other catalysts. Optimal reaction conditions for these three catalysts were achieved at 150 °C for 1 hour, using 2-propanol as the hydrogen source. Under these reaction conditions, the ZrOCl?·8H?O catalyst achieved 95.5% conversion of FOL and 30.3% yield of 1,2-PeD, while the VOSO?·H?O catalyst attained 80.5% conversion of FOL and 36.9% yield of 1,2-PeD. Both results were obtained with a low catalyst concentration of 0.6 mmol%. Meanwhile, the FeCl3·6H2O catalyst converted 94.9% of FOL and yielded 30.9% of 1,2-PeD, using a lower catalyst concentration of 0.4 mmol%. Kinetic studies suggested that the reactions likely follow pseudo-first-order kinetics with experimental activation energies (Ea) of 65 kJ/mol, 55 kJ/mol, and 37 kJ/mol for ZrOCl?·8H?O, VOSO?·H?O, and FeCl?·6H?O catalysts, respectively. These findings highlight the potential of transition-metal-based catalysts in achieving high efficiency with low loading, emphasizing their suitability for industrial applications
