Abstract

Abstrak – Pemanfaatan energi listrik sebagai upaya menciptakan green energy memerlukan suatu tindakan yang mendukung produksi energi yang efisien dengan menggunakan satu atau lebih energi alternatif yang dapat digabungkan menjadi sumber energi terdistribusi. Permasalahan pokok permintaan sumber energi yang semakin meningkat adalah keandalan sistem dan kualitas daya. Kualitas daya berkaitan dengan pengurangan nilai rugi-rugi daya listrik, berkurangnya nilai jatuh tegangan serta kontinuitas penyaluran energi listrik yang baik. Penambahan distributed generation (DG) pada sistem eksisting dinilai mampu mengurangi permasalahan kualitas daya dan meningkatkan keandalan sistem. Penelitian ini membahas optimasi penempatan DG dengan menggunakan metode Cat Swarm Optimization dan Krill Herd Algorithm. Optimasi dilakukan dengan menginjeksi DG pada sistem eksisting. Dari proses optimasi dengan CSO diperoleh penurunan rugi daya sebesar 0,2 % sedangkan dengan KHA diperoleh penurunan 29,5 %. Perbaikan profil tegangan dengan metode KHA dinilai lebih baik dari CSO dengan nilai diatas 0,99 p.u sedangkan CSO 0,96 p.u. Penelitian ini mengindikasikan bahwa metode KHA lebih baik daripada metode CSO.Kata Kunci — Distributed Generation, Cat Swarm Optimization, Krill Herd Algorithm.

Abstract

Pembangkit listrik tenaga surya pada umumnya tidak dapat bekerja pada daya maksimum dengan sendirinnya, karakteristik tegangan PV pada umumnya mengikuti tegangan batarai atau beban yang terhubung langsung ke PV. Intensitas cahaya yang diterima oleh modul-modul PV pasti tidak semuanya mendapatkan iradiasi yang seragam, sehingga daya yang dihasilkan tidak optimal dan menimbulkan multi-peak. Untuk mengoptimalkan daya dari PV diperlukan sistem Maximum Power Point Tracking (MPPT). Namun metode yang sering digunakan masih sering terjebak dalam local peak dan waktu konvergen yang lama. jurnal ini membandingkan performa pelacakan dan waktu pelacakan menggunakan 2 metode, yaitu Ant Colony Optimization (ACO) dan Particle Swarm Optimization (PSO). Hasil percobaan menunjukkan algoritma ACO mempunyai efisiensi rata-rata keseluruhan yang lebih unggul 1,58% dari PSO, namun algoritma ACO lebih lambat dalam pelacakanya.

Abstract

The era of post-truth has caused many cases where politicians bring down their opponents in various ways to get pleasure. This pleasure is known as schadenfreude. This study aims to determine the description and factors that influence scadenfreude in politicians. The subjects in this study were regional-level politicians from one of the Z political parties in city X as many as three subjects. The research method used in this research is a qualitative research method with a phenomenological approach. The main data collection technique in this study used semi-structured interviews. The data analysis technique in this study used content analysis. Researchers used triangulation of data sources with significant persons to meet the data validity requirements. The findings show that there is schadenfreude in politicians. Schadenfreude's emotional appears to politicians because of competition and tend to favor their own party. Politicians expect their opponents to lose, so they are happy with their victory. The defeat received by an opponent with bad morals is deemed appropriate to feel happy if the opponent loses. This research is an illustration for politicians not to engage in behavior related to schadenfreude because it has a negative impact on the democratic process.

Abstract

 Social conflict in Indonesia is caused by stereotypes, social identity and prejudice. This issue prompts research aimed at developing a model for the intention of social conflict in urban communities with predictors of stereotypes, social identity, and prejudice as early warning systems. This research refers to both correlational and sequential models. The study subjects were high school students in Sebatik, Nunukan, North Kalimantan. The sampling technique employed was quota-cluster random sampling, resulting in the participation of 108 adolescents. Data collection utilized scales for stereotypes, social identity, prejudice, and social conflict intention. Data analysis was conducted using structural equation modeling, specifically confirmatory factor analysis. The results indicate that the model for the intention of social conflict in urban communities meets the criteria for goodness-of-fit statistics, as evidenced by the values of chi-square=44.1, df=59, P value=0.92543, and RMSEA=0.000. Based on the research findings, stereotypes and social identity shape prejudice, thereby reinforcing the intention of social conflict in urban communities.

Abstract

Nomophobia has become a worrying phenomenon among young people. Therefore, research is needed to understand this condition more deeply. This study explores cross-cultural differences in nomophobia, emotional dysregulation, self-control, and smartphone use among a sample of university students in Yogyakarta, Indonesia, and Pahang, Malaysia. In addition, it examines smartphone use as a mediator of the effects of emotional dysregulation and self-control on nomophobia. Currently, only a limited amount of research tests explicitly the nomophobia-mediated model across different countries. This study used a cross-sectional design that involved university students from Yogyakarta and Pahang, comprising 215 students from Yogyakarta and 211 from Pahang, resulting in 426 participants. Among these, 110 (25.8%) were female and 316 (74.2%) male, with an average age of 18 (SD = 3.4), who were recruited using purposive sampling. Manova and regression analyses were conducted to examine the hypotheses, with an initial assessment of data normality, multicollinearity, and homogeneity assumptions performed before the analysis. Data were collected using scales for nomophobia, emotional dysregulation, self-control, and smartphone use. The study results indicate that students from Pahang exhibit higher levels of smartphone use and nomophobia compared to those from Yogyakarta (mean: 37.03 vs. 52.137; F = 151.19, p = .000). Emotional dysregulation and smartphone use consistently demonstrate a significant positive role in nomophobia across national contexts (β = 0.191, p = 0.002), (β = -0.414, p = 0.000). At the same time, self-control does not have a significant direct influence on nomophobia. The findings indicate the significant role of emotional dysregulation and smartphone use in nomophobia, the management of which will have implications for mitigating nomophobia.
