Through out the 80% of children AIDS victim has a prenatal infection from their mother. The aim of this study is to know the relationship between CD4 value and HIV stadium at pregnant mother infected by HIV/AIDS. A descriptive method was applied in this experiment. The sample obtained, from 22 pregnant mothers victims diagnosed of HIV/AIDS infection in Posyansus RSUP. H. Adam Malik Medan since January 2012 until June 2013. Data obtained by measuring CD4 value before and after ARV theraphy, then statisticallyÂ analyzed. The result out showed that 12 of samples (55%) have low CD4 value before ARV theraphy below 200 m3. Than, CD4 value were increased after ARV theraphy not affected by the stadium status. CD4 value before and after ARV theraphy has a negative linear corellation with HIV stadium (r = -0,743) it can be conclude that increased of CD4 value give an indirect contribution to HIV stadium victims.

Every object is always moving, and movement of an object can occur at any time. The value of the motion which produced from an object can be very small to very large, and the impact of the movement can be at risk until very risky. For this reason, the movement of objects at risk must be observed whenever changes and observations for data retrieval can be done remotely. The purpose of this research to design an Internet of Things (IoT) devices that can observe and detect changes in the motion of an object. Â The device is designed to be small, around 44 x 48 millimeters with very low power consumption. The design phase begins with recording motion data using the MPU6050 accelerometer sensor as a motion detector, arduino nano as a control device, WiFi ESP8266 as a communication medium for sending data from a receiver apllication motion data with UDP protocol. The test results show that this device is very sensitive to detect changes in the motion and angle of X, Y and Z of an object.

Automatic fruit detection utilizing computer vision techniques has been carried out to help the agriculture and plantation industries. This study researches smart systems to detect bananas and ripeness classification utilizing residual neural networks. The method used to detect bananas is transfer learning from pretraned Model VGG-19. Whereas, in the bananas ripeness classification process, residual neural networks, which are trained from the start, are used. Sliding Windows is used to detect the position of bananas followed by Non-Max Suppression to summarize the results of several detected bananas. Previous studies were limited to the level of ripeness, but in this study, bananas are detected and followed by the level of bananas ripeness (raw, ripe, and overripe). This studyâ€™s data uses bananas which were mixed with other kinds of fruit. There two kinds of bananas detection architecture used in this study, VGG-19 and Restnet. After they were used to detect bananas, it was found that VGG-19 was more suitable. The results of this study are very satisfying as it is seen from the bananas detection testing percentage using VGG-19 architecture which shows 100% ripe bananas, 99 % raw bananas, and 100% overripe bananas.Keywords:Â Detection of banana, banana ripeness, Non-Max suppression, residual block.

Published: February 2023

Decisions are made by those who are authorized and responsible decision makings for an institution or organization. Many decisions involve stakeholders who are individuals and organizations who can be affected by the future consequences of these decisions, including decision-making on Internet data quota assistance distributed by the Ministry of Education and Culture to support students' online learning from home (LFH). This Assistance Policy is very appropriate and well provided during the Covid-19 Pandemic. However, in an effort to optimize and objectify distribution so that it is right on target, this research is proposed solutions for applying the analysis decision-making mode using Multi-criteria Decision-making (MCDM). The criteria used include the amount of internet data consumption, Academic credits, courses, and student's economic capacity. The criteria weighting method uses Rank-order Centroid (ROC) and reference point MOORA for determining the best alternative. Â The results showed that the implementation of the MCDM ROC-Reference MOORA method affected the preference value and alternative ranking of internet data quota assistance. This shows that the criteria weight value and the analysis method are critical aspects in decision-making. Differences in weight, even the slightest change in weight, can drastically change the final decision

Published: February 2023

The fifth generation (5G) technology offers high speed communication systems and requires a multi input and multi output (Multiple Input Multiple Output / MIMO) antenna system to increase customer capacity. This research proposes a microstrip antenna design for a fifth-generation (5G) communication system that works at a frequency of 3.5 GHz. The antenna was designed using the RT-Duroid R5880 substrate type with dielectric constant (Îµr) = 2.2, thickness (h) = 1.57 mm and loss tan (tan Î±) = 0.0009. To produce optimal parameter, the antenna is optimized using slit on the edge with a total of 2 pairs. The addition of an inset aims to reduce the reflection coefficientÂ of the proposed antenna. From the simulation results, the reflection coefficient value is -25 dB at a frequency of 3.5 GHz with a bandwidth of 220 MHz. The gain of the proposed antenna is 10 dB at a frequency of 3.5 GHz. The isolation coefficient obtained is -70 dB with a distance between (d) = 43 mm. The application of the MIMO antenna increases the gain by 49.52% compared to the single element microstrip antenna.

Published: February 2023

The government and the house of representatives of the Republic of Indonesia have approved the establishment of new autonomous regions namely South Papua Province, Central Papua Province, and Papua Mountains Province. The plenary meeting of parliament was set up on 30 July 2022. This establishment of 3 (three) provinces is accommodated in Law Number 2 of 2021 concerning special autonomy for Papua. Before the law was revised, the authority to form a new autonomous region was proposed by The Papuan People’s Assembly or Majelis Rakyat Papua and The Papuan People’s Representative Council or Dewan Perwakilan Rakyat Papua. This research aims to study the government’s communication strategy in conveying the goals of establishing the new autonomous regions in Papua. This study uses a descriptive analysis approach. Data was collected through interviews with informants involved in the formation of new autonomous regions and Papua community leaders. Secondary data was collected from media publication, official government websites, scientific publication, and reports. Laswell’s communication model is used for the evaluation of the government’s communication strategy. The study recommends that the government’s communication strategy should be more intensive through the ministry of home affairs to local government affected by the establishment new provinces, group communication between government and indigenous group, and interpersonal communication among Papuan’s elites who can influence public perception
