"Penelitian ini bertujuan untuk menguji teori audience effect dan melihat apabila teori dapat direplikasikan dalam bermain permainan ponsel bernama Piano Tiles, sebagai sebuah cara untuk mengatasi krisis replikasi yang seringkali menjadi tantangan dalam bidang studi psikologi. Empat puluh mahasiswa dibagi menjadi dua grup independen: dengan audiens, dan tanpa audiens, dan diminta untuk bermain game Piano Tiles serta mengisi survey singkat tentang tingkat evaluasi. Skor peserta dalam permainan digunakan sebagai variabel dependen yang utama, dan survei tingkat evaluasi digunakan sebagai variabel dependen sekunder. Hasil penelitian menunjukkan bahwa peserta dalam grup dengan audiens mendapatkan skor yang lebih tinggi secara signifikan dari peserta dalam grup tanpa audiens, bertentangan dengan drive theory oleh Zajonc. Kedua grup tidak mencapai tingkat evaluasi yang signifikan, membuktikan bahwa theory Rosenberg tentang tingkat evaluasi tidak berlaku untuk situasi ini. Teori distraction-conflict serta keterbatasan pada penghitungan skor pada permainan muncul sebagai alasan potensial mengapa hipotesis tidak didukung. Hasil dan implikasi studi ini dapat digunakan landasan untuk penelitian lebih lanjut mengenai audience effect pada penggunaan ponsel.

This study was aimed to test the audience effect theory and see if the theory can be replicated in playing a mobile phone game named Piano Tiles, as a way to address the replication crisis that has been a challenge in psychology field of study. Forty university students were divided into two independent-groups: one with audience and one with no audience, and were asked to play Piano Tiles game and fill out a short survey about levels of evaluation. The participants` score in the game acted as primary dependent variable and levels of evaluation survey was the secondary dependent variable. The result shows that participants with audience condition scored significantly higher than no audience condition, contrary to Zajonc`s drive theory. Both groups did not attain a significant evaluation apprehension, suggesting that Rosenberg`s evaluation apprehension theory did not appear in this situation. Distraction-conflict theory as well as the limitation of the scoring system of the game emerged as potential reason of the rejected hypotheses. The result and implications of this study can serve as a base for further research regarding audience effect in using mobile phone."

"Teknologi telekomunikasi seluler berkembang sangat pesat, mulai dari diluncurkannya generasi pertama 1G pada tahun 1980 dimana teknologi masih berbasis analog, generasi kedua 2G pada tahun 1990 dengan peralihan dari analog ke digital, hingga sekarang sudah memasuki generasi kelima 5G. Perkembangan ini sejalan dengan meningkatnya kebutuhan masyarakat akan koneksi internet yang cepat dan availabilitas tinggi. Teknologi 5G yang identik dengan bandwidth yang besar, kecepatan yang tinggi, dan coverage luas merupakan solusi untuk mengatasi kebutuhan tersebut. Di dalam teknologi 5G terdapat sistem antena MIMO yang memungkinkan multi-antena untuk beroperasi secara simultan sehingga dapat mengurangi efek multipath fading, meningkatkan kapasitas bandwidth, dan kecepatan data. Penggunaan lebih dari satu antena yang berdekatan mengakibatkan efek mutual coupling yang dapat menurunkan kinerja antena. Pada penelitian ini telah dirancang antena MIMO menggunakan metode Defected Ground Structure (DGS) untuk menurunkan nilai mutual coupling. Antena yang beroperasi pada frekuensi 2,3 GHz dan 3,5 GHz ini dirancang pada bahan FR-4 dengan elemen peradiasi berbentuk rectangular dengan penambahan slot rectangular. Telah dilakukan 4 skenario penyusunan antena dengan hasil simulasi dan pengukuran terbaik adalah antena MIMO dengan peletakan port diputar 900. Hasil simulasi antena pada frekuensi rendah diperoleh nilai bandwidth 109 MHz dan mutual coupling dari -21,72 dB hingga -28,25 dB, pada frekuensi tinggi diperoleh nilai bandwidth 130 MHz dan mutual coupling dari -27,85 dB hingga -30,58 dB. Hasil pengukuran antena pada frekuensi rendah diperoleh nilai bandwidth 189 MHz mutual coupling dari -19,43 dB hingga -33,63 dB, pada frekuensi tinggi nilai bandwidth 144 MHz dan mutual coupling dari -21,72 dB hingga -30,58 dB.

Mobile telecommunications technology has developed rapidly, beginning with the launch of the first generation (1G) in 1980, where the technology was still analog-based. It then transitioned to the second generation (2G) in 1990 with the shift from analog to digital. As of now, we have entered the fifth generation (5G). This development aligns with the growing public demand for high-speed and highly available internet. 5G technology, capable of providing extensive bandwidth, high speed, and wide coverage, emerges as a solution to meet these demands. Within 5G technology, the MIMO antenna system stands out, allowing multiple antennas to operate simultaneously, thereby mitigating the effects of multipath fading and enhancing bandwidth capacity and data speed. The use of more than one nearby antenna results in mutual coupling effects that can degrade antenna performance. In this research, MIMO antenna has been designed using the Defected Ground Structure (DGS) method to reduce mutual coupling values. This antenna, operating at frequencies of 2,3 GHz and 3,5 GHz, is designed using FR-4 material with rectangular radiation elements and the addition of rectangular slots. Four scenarios of antenna configurations have been carried out, and the best and measurement results were achieved with the MIMO antenna with the ports rotated 900. The simulation results at low frequencies yielded a bandwidth value of 109 MHz, and the mutual coupling ranged from -21,22 dB to -28,25 dB. At high frequencies, the bandwidth value was 130 MHz and the mutual coupling ranged from -27,85 dB to -30,58 dB. The measurement results at low frequencies yielded a bandwidth value of 189 MHz and the mutual coupling ranged from -19,43 dB to -33,63 dB. At high frequencies, the bandwidth value was 144 MHz and the mutual coupling ranged from -21,72 dB to -30,58 dB. Improvements in mutual coupling at low frequencies range from 4,66 dB to 7,74 dB, while at high frequencies range from 4,20 dB to 5,84 dB."
