Design and Simulation of Low Power and Voltage Micro Photovoltaic Cell for Mobile Devices

In this study, designed and simulated a micro photovoltaic cell circuit which is part of smartphone battery charging system sensor. Problem discussed in this paper was that smartphone are still charging battery from PLN through a wall outlet, but smartphone would be better off if it had other charging alternatives, such as being able to charge anywhere or mobile. This paper proposed used photovoltaic cell that can convert sunlight into electricity and it can charge the battery on a smartphone. Photovoltaic cell were integrated with smartphone batteries in photovoltaic IC to form a battery charging system that can charge smartphone. The design of the micro photovoltaic cell sensor section is based on from the references paper. Micro photovoltaic cell was design by modifying the resistor value in the micro photovoltaic cell circuit, so the output low voltage and power be able to charge the smartphone battery. Designed and simulated micro photovoltaic cell circuits will be carried out using LTSpice. The results that achived in this research, when shunt resistance value was configure negative, the voltage value around 200mV, the power value around 1,48µW. When the shunt resistance value was configure positive the voltage value around 199mV, the power value around 1,44µW. Analysis was carried out by comparing voltage values obtained in this study with previous studies. In this study, a smaller voltage value was obtained by modifying the resistor value in the micro photovoltaic cell circuit. The circuit design will later be implemented in 0.35µm CMOS technology

Sosialisasi Pentingya Kreativitas dan Cara Meningkatkan Kreativitas di PAUD Nur Ilahi Buaran

Kreativitas merupakan salah satu hal yang penting bagi kehidupan manusia, Dengan kreativitas manusia akan lebih mampu untuk memecahkan segala persoalan yang muncul dalam hidupnya. Anak-anak memiliki potensi kreativitas yang tidak terbatas dan dapat dikembangkan dengan berbagai hal sederhana. Pengabdian Kepada Masyarakat (PKM) adalah salah satu program yang dilaksanakan di Universitas Pamulang. Tujuan dari Pengabdian Kepada Masyarakat tersebut adalah untuk terjun langsung ke tengah-tengah masyarakat dalam rangka membantu memecahkan masalah yang dialami di dalam masyarakat tersebut. Dalam hal ini kami memilih tempat Pendidikan Anak Usia Dini (PAUD) Nur Ilahi Buaran sebagai tempat dilaksanakannya kegiatan PKM tersebut. PAUD Nur Ilahi buaran adalah tempat sarana belajar bagi anak-anak usia dini sebelum mereka memasuki bangku sekolah dasar. Di PAUD Nur Ilahi Buaran kami memberikan sosialisasi tentang pentingnya kreativitas anak usia dini dan cara meningkatkan kreativitas anak, serta kegiatan yang kami lakukan disambut baik dengan antusias oleh para orangtua dan masyarakat dilingkungan PAUD Nur Ilahi Buaran. Kami harap dengan adanya kegiatan ini, maka para orangtua akan lebih menyadari tentang pentingnya kreativitas anak mereka dan akan lebih tahu bagaimana cara meningkatkan kreativitas anak mereka

Nurse Mental Workload and Completeness of Documentation in COVID-19 Isolation Rooms

Aims : This study is to find out the relationship between nurse mental workload and completeness of documentation in isolation rooms during the COVID-19 pandemic. Design : This research was correlational with a cross-sectional approach. Methods : The design of this study was a quantitative study with a cross-sectional approach. This study used primary data obtained through direct observation using a questionnaire consisting of patient demographic data, the mental workload was measured by NASA-TLX (National Aeronautics and Space Administration Task Load Index validity test obtained the value of r= 0,690 – 0,775 and reliability test Cronbach’s Alpha value of 0,797 and the completeness of documentation was measured using the standard instrument for standard documentation evaluation of the Ministry of Health. The research population was nurses who treated COVID-19 patients in Pontianak. Sampling was done using non-probability sampling using a purposive sampling technique with inclusion criteria, nurses who treat Covid-19 patients for at least 5 months. The number of samples was 30 nurses and 24 nursing care documents. Data analysis in this study used the bivariate Spearman's Rho test Results : The results of Spearman's rho analysis showed a significant value or Sig. (2-tailed) of 0.026. Because the value of Sig (2-tailed) 0.026 was < less than 0.05, there was a significant relationship between mental workload and the completeness of nursing care documentation. Conclusions : The increase in the number of patients makes the workload higher because it is not proportional to the ratio of nurses to patients
