Peluang dan Ancaman Disruptif Digital untuk Negara Berkembang

2022-11-17T10:06:09+00:00

This research study aims to analyze digital disruptive opportunities and threats for the Indonesian state and nation. The method used in this research is qualitative analysis with a literature study approach. There are a number of digital economy practices that have caused Indonesia to lose potential state revenues. The interesting phenomenon of the case of Chinese tourists in Bali with WeChat Pay and Alipay has cost Indonesia foreign exchange, and is detrimental because the transactions are not recorded. The polemic about taxes on electronic transactions is still limited to tax collection in the e-commerce sector, while social media (Medsos) and over-the-top services (OTT) are still a polemic. This section also discusses mastery of data and transaction flows in the digital economy. The recommendations in this chapter focus on how Indonesia can address this “leakage”. One of them is through tax reform for e-commerce actors, equal level playing with businesses in Social Media, and other digital transactions.

Determinasi Pengetahuan Ibu dan Pengaruh Rokok terhadap Kejadian ISPA pada Balita

2023-01-30T19:37:18+00:00

ISPA disease occurs in toddlers because the child's immune system is still low. ISPA disease can be transmitted through saliva, sneezing, breathing air that contains germs that are inhaled by healthy people through their respiratory tract. Based on data from the Banjit health center, ARI is included in the 10 highest diseases in the working area of the Banjit health center, in 2022 ARI cases totaled 1184 cases. There were 371 cases in toddlers with ARI cases. The risk of smoking inside the house, residue can stick to curtains, sofas, roofs, even children's toys. Parents' smoking habit in the house makes toddlers passive smokers who are always exposed to cigarette smoke. The aim of the study was to determine (title) the factors associated with ARI in toddlers in the Banjit Health Center Work Area in 2022. using a quantitative cross-sectional method using the Simple Random Sampling technique. Data analysis looked for a relationship (title) using the chi square test, with independent variables and dependent variables (Knowledge, smoking habits, ARI under five). The study population was taken from 103 toddlers who were sick with ISPA from September to December 2022. With a sample of 84 toddlers. The results showed that there was a relationship between mother's knowledge (p-value = 0.002), smoking habits of family members (p-value = 0.004) and ARI in toddlers. The conclusion in this study is that there is a relationship between the determination of mother's knowledge and the effect of smoking on the incidence of ARI in toddlers. As an act of controlling ISPA in the working area of the Banjit Public Health Center, two risk factors are the top priority. Community support in creating a healthy living community movement (Germas) is especially sought not to smoke near toddlers.

The main reason people are still reluctant to eat or process milkfish is the large number of spines that are difficult to clean, this reduces their interest in eating milkfish. In this era of globalization, the entry of foreign cultures into Indonesia has had an impact on lifestyles and eating patterns as well as people's culture giving rise to many kinds of food that are unique, practical but still nutritious enough. From the circumstances and opportunities we try to solve social problems while simultaneously wanting to access large market opportunities. This study uses quantitative methods based on systematic facts or characteristics of certain populations factually and carefully. We have created a product that is liked by various groups and utilize social media to attract enthusiasts. Looking at cities in Indonesia where the density is dominated by youth, they are the biggest contributors to urban development in all sectors. The two conditions above are what underlies the birth of this Milkfish Mci business, namely by producing modern processed milkfish products and utilizing social media to attract youth. With the existence of processed milkfish products that are in accordance with the interests of the target market. Because milkfish contains higher nutrition, it is of interest to the general public. For transactions that themselves use the method commonly used by the public. Marketing information uses media that is often found by the target market with the online platform services available in today's digital era. Especially milkfish which is abundant in the East Java area.

Analisis dan Simulasi Efisiensi Kinerja Sepic Konverter Berbasis Kontroler Konvensional

2024-04-07T08:24:20+00:00

The technology of components and electronic hardware has evolved to be able to produce a DC/DC current system for power, which is achieved by converting the DC power to higher or lower voltage. This DC voltage variable is commonly called the DC-DC Converter. This final task aims to find out the performance of the DC-DC Sepic Converter series design. The simulated testing of the system using SIMULINK/MATLAB software is subsequently obtained from the data analysis of the theoretical output voltage data and the monitoring of measurements that can be analyzed to determine the error level as well as the level of efficiency of the design of the sepic converter. The test was conducted by setting a constant input voltage of 12 V, a frequency of 50 kHz, with a duty cycle variation of 5% to 65% and a given load of 20 Ω. The result of the design of the Sepic Converter at the time of open loop mode with the value of duty Cycle of 5% produces a minimum voltage that is 0,38 V. Subsequently, when given the duty cicle value of 65%, the maximum voltage is 21,22 V error with the highest error rate of 1 V obtained at the 13th data trial. The average error value is 0,642 V and the standard deviation value is 0,453 V, the greatest efficiency point is 78,50% at the moment of the cycle duty value of 65. While the results of the testing of the Set of Sepic Konverters at the close loop mode, the input tension is given constantly 12 V. The configuration for the parameter value of PI is also constant, namely at the set point of 22,22 V, it is 21,97 V with an error difference 0,25 V.
