Penggunaan Hukum Hagen-Poiseuille dalam Penentuan Koefisien Viskositas Zat Cair dengan Prinsip Kontrol Berat Berbantuan Software Logger Pro

Pengukuran koefisien viskositas zat cair menggunakan hukum Hagen-Poiseuille dengan metode Microcomputer Based Laboratory telah dilakukan. Viskositas merupakan ukuran penolakan fluida terhadap perubahan bentuk di bawah tekanan shear. Hukum Hagen-Poiseuille digunakan dalam penelitian ini karena zat cair yang digunakan merupakan zat cair Newtonian. Tangki viskometer kapiler yang dikaitkan ke sensor gaya diisi zat cair untuk kemudian dialirkan keluar melalui pipa kapiler dengan panjang (9,8±0,09)×10-2 m dan diameter dalam (2,1620±0,0096) ×10-3 m. Data penurunan massa zat cair direkam menggunakan sensor gaya buatan Vernier Tecnology dan analisis fitting data menggunakan software Logger Pro. Nilai karakteristik waktu diperoleh dari hasil fitting data digunakan untuk perhitungan koefisien viskositas zat cair menggunakan hukum Hagen-Poiseuille. Dari percobaan ini diperoleh nilai koefisien viskositas air sebesar (1,063±0,113) mPa.s yang sesuai dengan nilai acuan teori yaitu 1,002 mPa.s, oli SAE 10W-30 sebesar (79,01±8,90) Pa.s sesuai dengan nilai acuan teori 76,8 Pa.s, dan gliserin sebesar (593,4±56,7) mPa.s sesuai dengan nilai acuan teori 612 mPa.s.Measurement of liquid viscosity coefficient using Hagen-Poiseuille law with Microcomputer-Based Laboratory method has been done. Viscosity is the fluid declination measure of form changes under sheer pressure. Hagen-Poiseuille law is used in this study because the liquid used is a Newtonian liquid. Capillary viscometer tanks attached to force sensors are filled with liquid to be streamed out through capillary tubes of length (9.8 ± 0.09) × 10-2 m and the inner diameter (2.1620 ± 0.0096) × 10-3 m. Data on the mass degradation of liquids was recorded using a Vernier Technology force sensor while the data fitting analysis using Logger Pro software. The time characteristic values which obtained from the data fittings are used in the calculation of the liquid viscosity coefficient using Hagen-Poiseuille law. From this experiment, the obtained water viscosity coefficient value is (1.063 ± 0.113) mPa.s corresponds to the reference value of the theory is 1.002 mPa.s, the SAE oil 10W-30 is (79.01 ± 8.90) Pa.s corresponds to the reference value of the theory 76.8 Pa.s, and glycerin is (593.4 ± 56.7) mPa.s corresponds to the reference value of the theory 612 mPa.s

Socializing in emergencies—A review of the use of social media in emergency situations

AbstractSocial media tools are integrated in most parts of our daily lives, as citizens, netizens, researchers or emergency responders. Lessons learnt from disasters and emergencies that occurred globally in the last few years have shown that social media tools may serve as an integral and significant component of crisis response. Communication is one of the fundamental tools of emergency management. It becomes crucial when there are dozens of agencies and organizations responding to a disaster. Regardless of the type of emergency, whether a terrorist attack, a hurricane or an earthquake, communication lines may be overloaded and cellular networks overwhelmed as too many people attempt to use them to access information. Social scientists have presented that post-disaster active public participation was largely altruistic, including activities such as search and rescue, first aid treatment, victim evacuation, and on-line help. Social media provides opportunities for engaging citizens in the emergency management by both disseminating information to the public and accessing information from them. During emergency events, individuals are exposed to large quantities of information without being aware of their validity or risk of misinformation, but users are usually swift to correct them, thus making the social media “self-regulating”

LEAN HOSPITAL MANAGEMENT IMPLEMENTATION IN RURAL PRIVATE HOSPITAL: ITS EFFECT ON JOB SATISFACTION AND TURNOVER INTENTION

Abstract. Previous studies in Indonesia examining the effect of lean hospital management implementation on employee’s job satisfaction and turnover intention had not been done. Results from studies in other countries regarding the effect of lean hospital for employee’s wellbeing also point to contradictions, being positive or negative. The expected positive effect of lean hospital implementation for employee’s wellbeing is to encourage the sustainability of lean management implementation in hospital. Adina MC Hospital as a rural private hospital in Central Java has implemented the lean concept to improve the quality of hospital service in the last seven months. This study is aimed to determine the effect of lean hospital tools (Value Stream Mapping and 5S) to job satisfaction and turnover intention of hospital employees in the context of job demands as mediator and job resources as moderator. Questionnaires were given to 78 employees of Adina MC Hospital who had been working for more than one year. All data and hypotheses testing were analyzed using smartPLS. The findings show that the implementation of lean hospital tools (5S) is positively associated with job satisfaction. The influence of lean hospital tools' VSM could not be seen because it has been dropped out in reliability testing instruments. Job satisfaction was also found to be negatively associated with turnover intention. In the context of job resources, the findings show that job resources moderate the correlation between lean hospital tools (5S) implementation with job satisfaction, so lean hospital implementation could promote employee’s job satisfaction when supported by adequate job resources. Job resources are also not found to moderate the correlation between job demands with job satisfaction and both hypotheses of job demands mediate the correlation between lean hospital tools implementation with job satisfaction and turnover intention have been rejected.Keywords: lean hospital, job satisfaction, turnover intention, job demands, job resource
