Abstract

Tujuan dari peneltian ini untuk melakukan uji dampak Sistem informasi dan Teknologi atas Kinerja di Pt.Sarana Sirkuitindo Utama. Maka pada pelaksanaannya digunakan metode deskriptip, melakukan uji (butir pernyataan, korelasi, regresi simpel dan ganda, determinan, serta parsial, simultan). responden menurut lama kerjannya yaitu 8 orang bekerja selama 1-5 tahun dengan porsentase 12,70%, 2 orang bekerja selama 6-10 tahun dengan porsentase 3,17%, 11 orang bekerja selama 11-15 tahun dengan porsentase 17,49%, 31 orang   bekerja selama 16-20 tahun dengan porsentase 53,95%, 2 orang bekerja selama 21-25 tahun dengan porsentase 3,17% dan 6 orang bekerja selama 26-30 tahun dengan porsentase 9,52%. Sehingga rata-rata responden yang telah mengisi kuesioner telah bekerja selama 16 tahun lebih. Dari hasil itu diharapkan hasil tanggapan yang diperoleh akan lebih objektif. Penelitian ini menggunakan pendekatan kuantitative , hasil penelitian ada impak antara sistem informasi terhadap kinerja karyawan kemudian ada impak antara teknologi   terhadap kinerja karyawan dan juga ada impak antara sistem informasi dan teknologi   terhadap kinerja karyawan secara bersama –sama atau secara simultan  Dari hasil uji koefisien determinasi di ketahui bahwa nilai Rsquare yaitu 0,313 atau sama dengan 31,3 % yang berarti bahwa variabel sistem informasi dan teknologi memberikan kontribusi atau pengaruh terhadap variabel kinerja karyawan sebesar 31,3%. Keterbatasan penelitian ini hanya mencakup area dengan variabel sistem informasi dan teknologi, yang saat ini jauh lebih berkembang, sangat terbuka untuk dilakukan penelitian lebih lanjut di masa mendatang.

Abstract

Fenomena pesatnya Transformasi Digital (TD) telah mengubah cara startup Indonesia mengakses pasar internasional. Namun, masih terdapat kesenjangan dalam pemahaman mengenai bagaimana teknologi digital benar-benar berperan dalam mempercepat proses internasionalisasi. Masalah utama penelitian ini adalah terbatasnya kajian empiris yang menjelaskan mekanisme penggunaan teknologi digital—seperti e-commerce, media sosial, big data analytics, dan cloud computing—dalam mengatasi hambatan geografis, sumber daya, serta regulasi yang dihadapi startup di negara berkembang. Penelitian ini bertujuan untuk menganalisis peran TD dalam membentuk strategi Akses Pasar Internasional (API) bagi startup Indonesia serta mengidentifikasi faktor-faktor kunci yang mendukung dan menghambat proses tersebut. Metode yang digunakan adalah pendekatan kualitatif melalui kajian pustaka (literature review), dengan menganalisis berbagai sumber ilmiah terkini (2020–2025) dari jurnal nasional dan internasional yang relevan dengan topik TD dan internasionalisasi startup. Data dianalisis secara deskriptif-kualitatif dengan mengelompokkan literatur berdasarkan tema utama dan mensintesis temuan untuk memperoleh pemahaman yang utuh. Hasil penelitian menunjukkan bahwa TD berperan signifikan sebagai akselerator dalam proses internasionalisasi digital. Tiga tema utama yang ditemukan adalah: (1) Internasionalisasi Berbasis Platform, yang memungkinkan startup menembus pasar global tanpa infrastruktur fisik di luar negeri; (2) Pengembangan Kapabilitas Dinamis Digital, yang memperkuat kemampuan adaptasi terhadap perubahan teknologi dan pasar; serta (3) Navigasi Tantangan Ekosistem, yang mencakup keterbatasan talenta digital, infrastruktur, dan regulasi lintas negara. Kesimpulannya, TD tidak hanya menjadi alat operasional, tetapi juga fondasi strategis dalam membangun keunggulan kompetitif global. Startup yang adaptif, inovatif, dan berbasis data memiliki peluang lebih besar untuk sukses di pasar internasional. Penelitian ini memberikan implikasi praktis bagi pembuat kebijakan dan pelaku industri untuk memperkuat kebijakan dan ekosistem digital yang mendukung internasionalisasi startup di Indonesia.

Abstract

The 2.3 GHz frequency band is one of the recommended spectrums for 5G deployment due to its favorable propagation characteristics and capability to support high data throughput. However, microstrip antennas operating in this band often suffer from limited bandwidth and radiation efficiency. This research aims to design and implement a 2×2 MIMO microstrip antenna using a square patch with a U-slot and an inset-feed technique to enhance bandwidth and radiation performance for 5G applications. The initial antenna dimensions were calculated using standard microstrip theory, followed by modeling and optimization using CST Microwave Studio Suite 2019. The optimized antenna was then fabricated and tested using a Vector Network Analyzer (VNA) and radiation pattern measurements. Experimental results show that the antenna operates around 2.3 GHz with bandwidth values ranging from 61 to 65 MHz, VSWR below 1.2, and an axial ratio of 1.23 dB, indicating circular polarization. Additionally, the measured gain reaches 6.98 dB. These results demonstrate that the U-slot modification combined with inset-feed implementation effectively improves antenna performance, making the design suitable for MIMO systems in 5G networks.

Abstract

Introduction: Dental caries is a significant global health concern. Factors such as socioeconomic status, diet, oral hygiene, and access to dental care influence its prevalence. Limited information exists on dental health in remote sea-floating villages. This study aimed to analyze the correlation between demographic and environmental factors and dental caries prevalence in a sea-floating community. Methods: This cross-sectional study was conducted in Malahing Village, a sea-floating village located adjacent to the Makassar Strait, 4 km east of Bontang city. Seventy-two respondents aged 5–59 years were examined for the DMFT index, while intrinsic factors (demographic and dental health behaviors) and extrinsic factors (environmental and dental health services) were collected via questionnaires. Data were analyzed using descriptive univariate analysis to determine variable characteristics and Spearman’s correlation analysis. Results: Dental caries prevalence was 98.61%, with a DMFT index of 10.01. Age (r=0.564, p=0.001), education (r=0.370, p=0.002), and occupation (r=0.273, p=0.020) showed strong, moderate, and weak positive correlations, respectively. Rainwater exposure (r=-0.353, p=0.003) showed a moderate negative correlation. Sex, dental health behaviors, water source, and dental visits were not significantly correlated with caries prevalence. Adults showed highest prevalence (66.67%) but low DMFT index (1.00). Government employees had high DMFT scores (4.61). Twice-daily brushing was uncommon (66.67%) among individuals with high DMFT scores (6.15). Patients who never visited a dentist (44.44%) showed high DMFT scores (8.33). Conclusions: In this underserved coastal community, demographic disadvantages and environmental exposures, particularly water sources, combined with limited dental care contribute to an elevated caries burden compared to the national and international levels. Despite complex associations with environmental factors, rainwater exposure showed negative correlation with caries prevalence, highlighting measurement challenges. The high proportion of patients never visited a dentist, low oral health awareness, and nonstandard water management highlight critical service gaps.

Abstract

Background: Pregnancy involved physical, emotional, and social changes, making spousal support crucial in reducing stress, anxiety, and improving maternal quality of life. However, participation of mothers and husbands in prenatal classes in Indonesia remained low. A hybrid education model (online and face-to-face) had the potential to address these limitations.Objective: This study aimed to assess the effectiveness of a digital-based hybrid companion class on improving the quality of life of pregnant women in Magelang City.Methods: This was a quasi-experimental study with a non-randomized pretest-posttest with control group design. The sample consisted of 60 couples of reproductive age (30 intervention, 30 control) selected through simple random sampling. The hybrid class intervention included modules, educational videos, and mentoring through WhatsApp, conducted in four sessions. Quality of life was measured using WHOQOL-BREF at three time points and analyzed with GLM-RM.Results: The intervention significantly improved the quality of life of pregnant women in the psychological domain (p = 0.001; η² = 69.3%), social domain (p = 0.021; η² = 34.2%), and environmental domain (p = 0.001; η² = 65.7%), while the physical domain was not significant (p = 0.510).Conclusion: The digital-based hybrid companion class was effective in improving the quality of life of pregnant women in psychological, social, and environmental aspects. Integration of the program into antenatal services was recommended to enhance the role of husbands in pregnancy care.
