Abstract

This study aims to analyze the influence of Teacher Discipline and Transformational Leadership on Teacher Job Satisfaction and Teacher Professionalism in schools. Using a quantitative approach with path analysis, the results of the study indicate that Teacher Discipline has a significant influence on Teacher Job Satisfaction and Teacher Professionalism, both directly and through job satisfaction channels. In addition, Transformational Leadership also has a significant influence on both variables, although slightly lower than teacher discipline. Teacher Job Satisfaction acts as a mediator between teacher discipline and transformational leadership with teacher professionalism. This finding confirms the importance of the role of discipline and transformational leadership in improving teacher professionalism through increasing job satisfaction. This study suggests that schools focus more on developing supportive discipline and leadership and creating a work environment that improves teacher satisfaction and professionalism.

Abstract

Background: The Indonesian Carbon Exchange (IDX Carbon) has emerged as a critical mechanism for carbon trading, introducing carbon units as securities rather than commodities. Despite this development, challenges remain in ensuring the integrity of carbon markets, including issues of double counting, manipulation of carbon unit measurements, and regulatory gaps. Objective: This study aims to examine the implementation of Carbon Emission Disclosure on Market Reaction with Green Investment as a mediating variable in companies listed on IDX Carbon. Methods: This study employed a quantitative research approach using SmartPLS with PLS-SEM. Hypothesis testing applied a t-statistic threshold of 1.96 and a significance level of α = 5% (p-value < 0.05). Results: All variables had Cronbach's Alpha values above 0.95 and AVE values above 0.66, indicating high reliability and validity. The R² value of Green Investment (Z) was 0.983 and Market Reaction (Y) was 0.925, indicating strong predictive relevance. Hypothesis testing revealed: (1) Green Investment significantly affects Market Reaction (t = 9.422, p = 0.000); (2) Carbon Emission Disclosure significantly affects Green Investment (t = 6.017, p = 0.000); (3) Carbon Emission Disclosure significantly affects Market Reaction (t = 2.655, p = 0.000); and (4) Carbon Emission Disclosure significantly affects Market Reaction through Green Investment as a mediating variable (t = 8.672, p = 0.000). All four hypotheses were accepted. Conclusion: Carbon Emission Disclosure has a significant direct effect on both Green Investment and Market Reaction in IDX Carbon-listed companies. Green Investment also serves as a significant mediating variable between Carbon Emission Disclosure and Market Reaction, highlighting the importance of transparent carbon emission reporting in supporting sustainable finance in Indonesia.

Abstract

Kerajinan batik merupakan aset budaya dan aset pariwasta yang dapat dikembangkan di Desa Perkebunan Tanjung Kasau Kabupaten Batu Bara yang cukup edukatif dan aplikatif yang ditunjukan dengan seni batik yang dapat membantu kunjungan pariwisata. Peluang Usaha UMKM Batik di Desa Perkebunan Tanjung Kasau memiliki banyak potensi untuk memperoleh tingkat keuntungan yang cukup tinggi. Namun, disayangkan potensi yang ada belum dapat maksimal dilakukan, hal itu disebabkan kurangnya sumber daya manusia yang menjadi regenerasi sebagai pengrajin batik dan juga kurangnya minat masyarakat sekitar untuk memakai produk batik tulis dan cap yang memiliki karya seni tinggi, masyarakat lebih memilih memakai batik yang dijual lebih murah dan sudah siap pakai. Kelompok UMKM batik ini memanfaatkan media sosial Instagram sebagai media untuk berpromosi. Permasalahan dari pembatik pada kelompok UMKM ini belum mengoptimalisasikan pemanfaatan media sosial Instagram sehingga engagement rate yang didapatkan masih terbilang rendah. Oleh karena itu pelaksanaan pengabdian ini bertujuan untuk dapat mengoptimalkan penggunaan media sosial khusunya Instagram agar mampu meningkatkan upaya promosi sehingga berdampak pada peningkatan penjualan batik.

Abstract

Emas merupakan aset lindung nilai (save haven) yang banyak digunakan investor untuk meengurangi risiko ketidakpastian ekonomi dan geopolitik. Namun,pergerakan harga emas yang cenderung volatile dan tidak stabil menyebabkan proses peramalannya menjadi kompleks. Penelitian ini bertujuan untuk menganalisis kemampuan model hibrida ARIMA-GARCH dalam meramalkan harga emas selama periode ketidakpastian global. Data yang digunakan berupa harga penutupan emas harian (XAU/USD) dari Januari 2020 hingga Maret 2025. Hasil penelitian menunjukkan bahwa model ARIMA (2,1,22) memiliki nilai Akaike Information Criterion (AIC) terendah, tetapi tidak memenuhi asumsi stasioneritas karena nilai modulus autogressive yang tidak stabil. Pengujian lebih lanjut menunjukkan adanya efek ARCH pada residual, sehingga diperlukan permodelan GARCH. Model GARCH (0,1,2) dengan komponen rata-rata MA(2) dipilih sebagai model terbaik karena mampu mengatasi heteroskedastisitas yang ditunjukkan oleh hasil uji ARCH dengan nilai probabilitas lebih besar dari 0,05. Evaluasi kinerja model menghasilkan nilai Mean Absolute Percentage Error (MAPE) sebesar 18,37%, yang menunjukkan tingkat akurasi peramalan yang baik. Hasil penelitian mengindikasikan bahwa model ARIMA-GARCH cukup efektif dalam memprediksi harga emas pada periode volatilitas tinggi dan dapat digunakan sebagai alat pendukung pengambilan keputusan investasi

Abstract

This study aims to analyze the influence of Financial Influencers and Social Media Algorithms on stock investors’ Fear of Missing Out (FOMO) through Financial Literacy as an intervening variable. The development of digital social media has transformed investor behavior in making investment decisions, particularly due to the influence of financial influencer content and social media algorithm systems that intensively display investment-related information to users. This study employed a quantitative approach using the Structural Equation Modeling–Partial Least Square (SEM-PLS) method with SmartPLS 4 software. The research sample consisted of 200 stock investors selected using purposive sampling techniques. Data collection was conducted through questionnaires using a Likert scale. The results showed that Financial Influencers and Social Media Algorithms had a positive and significant effect on Financial Literacy and stock investors’ Fear of Missing Out (FOMO). In addition, Financial Literacy also had a positive and significant effect on Fear of Missing Out (FOMO). The indirect effect testing demonstrated that Financial Literacy significantly mediated the influence of Financial Influencers and Social Media Algorithms on stock investors’ Fear of Missing Out (FOMO). This study proves that the development of the digital social media ecosystem plays an important role in shaping modern stock investor behavior, both from rational and psychological investment perspectives.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh kepemimpinan, komunikasi, dan pengembangan karir terhadap produktivitas kerja karyawan Bank BPR NBP 18. Penelitian dilatarbelakangi oleh belum tercapainya target produktivitas kerja Account Officer selama periode Juli–Desember 2025, yang menunjukkan perlunya identifikasi faktor-faktor yang memengaruhi produktivitas kerja. Penelitian menggunakan pendekatan kuantitatif dengan metode survei. Populasi penelitian terdiri atas 36 Account Officer Bank BPR NBP 18, dengan teknik pengambilan sampel menggunakan metode sensus sehingga seluruh populasi dijadikan responden. Data dikumpulkan melalui kuesioner dan dianalisis menggunakan regresi linear berganda yang didahului dengan uji validitas, reliabilitas, dan uji asumsi klasik. Hasil penelitian menunjukkan bahwa kepemimpinan berpengaruh positif dan signifikan terhadap produktivitas kerja (t = 2,109; p = 0,043), demikian pula komunikasi yang berpengaruh positif dan signifikan (t = 2,355; p = 0,025). Sebaliknya, pengembangan karir tidak berpengaruh signifikan terhadap produktivitas kerja (t = 0,402; p = 0,691). Secara simultan, kepemimpinan, komunikasi, dan pengembangan karir berpengaruh signifikan terhadap produktivitas kerja (F = 15,741; p < 0,001) dengan koefisien determinasi sebesar 59,6%, yang menunjukkan bahwa ketiga variabel mampu menjelaskan sebagian besar variasi produktivitas kerja. Penelitian ini menyimpulkan bahwa peningkatan produktivitas kerja di Bank BPR NBP 18 lebih dipengaruhi oleh kepemimpinan yang efektif dan komunikasi organisasi yang baik, sehingga kedua aspek tersebut perlu menjadi prioritas dalam pengelolaan sumber daya manusia.
