Performance Analysis of 4x4 MIMO and 8x8 MIMO Antena Implementation of Private 5G Networks in Industrial Area

Private 5G represents a promising wireless network technology that offers a wide range of opportunities for mobile operators. It enables them to meet the increasing data demands of their customers and provide enhanced capacities and user experiences. However, before deploying Private 5G, it's crucial to prepare the foundation properly, especially when choosing the right antena and Radio Frequency (RF) band. This research project focuses on evaluating the implementation of 4x4 MIMO and 8x8 MIMO antenas in the Greater Jakarta industrial area, covering a 35 km2 area, operating at a frequency of 2300 MHz with a 40 MHz bandwidth. The study involved data rate measurements and determined the number of required sites based on different modulation schemes. The findings revealed that using an 8x8 MIMO antena resulted in a data rate twice as high as that achieved with a 4x4 MIMO antena and required only a quarter of the sites. Additionally, simulation results demonstrated that the 8x8 MIMO antena provided better SS-RSRP and SS-SINR values compared to the 4x4 MIMO antena, with values of -91.51 dBm and 8.52 d

Construction of BPJS National Health Insurance Membership Regulations in Indonesia

The issuance of the BPJS National Health Insurance Law was a government effort to enhance the welfare of citizens by making it mandatory for them to become BPJS health insurance participants, with a deadline set for January 2019. However, as of May 2022, around 13.79% (according to Worldometer) or 12.26% (according to the Home Ministry) of citizens have not yet joined, due to various factors, including issues related to the BPJS health insurance membership regulations. This paper aims to provide clarity on the construction of health insurance membership regulations as outlined in Law Number 24 of 2011 concerning the Social Security Agency connected to the National Social Security System. The research utilized a descriptive analysis with a statutory approach, along with secondary data obtained through a library study to collect data, and systematic and teleological analysis to analyze the data. The results of the study indicate that the construction of BPJS health insurance membership regulations follows the Stufen theory, which is in accordance with the hierarchy of occupying concrete norms (Hans Kelsen) or formalgezets (Hans Nawiasky).

Studi X-ray Diffractometry pada Struktur Coating Alumunium yang Dipreparasi Denganmetode Mechanical Alloying

X-RAY DIFFRACTOMETRY STUDY ON STUCTURE OF ALUMINUM COATING PREPARED BY A MECHANICAL ALLOYING METHOD. Aluminum (Al) coating was successfully deposited on the surface of low carbon steel by using a mechanical alloying method. After coating deposition, the aluminum coating was annealed in vacuum furnace of 5.6 Pa at elevated temperatures of 600 oC, 700 oC and 800 oC. Phase transformation and structure changes in aluminum coating at varying curing temperatures ware studied by means of X-ray diffraction (XRD). The presence of Al (111) diffraction peak from the results of XRD characterization indicates thatAl coating was deposited on the surface of low carbon steel. On the other hand, the results of XRD characterization show the phase transformation and structure changes of Al coating due to the effect of annealing temperature. It was indicated by the presence of diffraction peaks of Al3,2Fe, Fe3Al, dan Fe0,8Al0,2 after annealing.An increase in annealing temperature leads to decrease in d-spacing, lattice parameter, and lattice constant Fe0,8Al0,2(110). However, the lattice strain and dislocation density are likely to increase. Structure coating evolution occurred due to the diffusion of aluminum to the substrate of low carbon steel

The Risk Quotient of Sulfide Hydrogen Toward Lung Vital Capacity of People Living Around Landfill Area

Waste is one of factors causing air pollution in Palembang City. Volume of waste that should be processed increases every day, while condition of waste management service is still 70% of the total volume. The waste processing is managed by using open dumping system, which affects on the increase of air pollution. One of gases that exist as effect of the process of organic compound decomposition of anaerobic bacteria from garbage is sulfide hydrogen (H2S) pollutant which can promote health disorders, especially respiratory system. This study aimed to analyze correlation between characteristics (age, sex, nutritional status, smoking, and living distance) and the risk quotient of sulfide hydrogen concentration in air ambient to the lung capacity of people around landfillarea. This study used cross-sectional design with the sample of 78 people around landfill area. Data analysis used double logistic regression. Results showed that nutritional status (p value = 0.022, OR = 12.085) and RQ (p value = 0.016; OR = 7.547) significantly related to lung vital capacity of people around landfill area. People around landfill area having worse nutrition and lower RQ than the median were potential to have lung vital capacity disorder. The dominant variable significantly influencing to lung vital capacity of people living around Sukawinatan Landfill is nutritional status

Interferon-mediated intracellular signalling Modulation of different phospholipase activities in Burkitt lymphoma cells

AbstractThe effect of interferon-α on Daudi lymphoma cells either sensitive or resistant to the action of this cytokine has been analysed in terms of phospholipase C (PLC) and D (PLD) activities. Results have shown a combined modulation of PIP2-specific phospholipase C and phospholipase D. In particular, a decreased activity of PIP2-specific PLC has been found, concomitant to a PLD-mediated phosphatidylcholine hydrolysis, suggesting that the intracellular signaling activated by interferon in Daudi cells involves a phospholipase D/phosphohydrolase pathway
