Abstract

Achievement emotions are recognized as key factors influencing students' success in mathematics. However, no Achievement Emotions Questionnaire for Mathematics (AEQ-M) specifically tailored for Indonesian senior high school students has been developed. This study aims to translate the 68-item AEQ-M into Indonesian and validate its use for senior high school students in Indonesia, termed AEQ-M-SHS-I. A purposive cluster sampling method was used to select 198 tenth and eleventh-grade students in West Java, Indonesia. Data analysis included descriptive statistics, item analysis, and reliability testing. Structural, convergent, and discriminant validity were assessed using confirmatory factor analysis (CFA). All of data analyses were supported by SPSS 26.0 and AMOS 26.0. The Indonesian AEQ-M-SHS-I consists of ten factors and 68 items, all demonstrating good discriminant validity. CFA showed good structural model fit indices (e.g., X²/df = 2.245, CFI = 0.937, TLI = 0.950, SRMR = 0.059, RMSEA = 0.079). Moreover, all of ten emotions in the AEQ-M-SHS-I had ideal convergent validity. Additionally, the tool exhibited high internal consistency (? = 0.868). These results indicate that the AEQ-M-SHS-I is a valid and reliable instrument for assessing achievement emotions in mathematics among Indonesian senior high school students.

Abstract

Abstrak Revisi Undang-Undang Cipta Kerja (Omnibus Law) melalui UU No. 6 Tahun 2023 telah memicu gelombang demo buruh nasional, khususnya aksi Konfederasi Serikat Pekerja Indonesia (KSPI) di Cikarang pada 2024, bersamaan dengan sengketa Upah Minimum Provinsi (UMP) 2025 yang digugat ke Mahkamah Konstitusi (MK). Pasca-Pemilu 2024, ketidakpastian regulasi ini mengancam stabilitas industrial relation dan target ekonomi RPJMN 2025-2029. Penelitian ini bertujuan menganalisis dinamika yuridis konflik tersebut, mengidentifikasi kelemahan hukum ketenagakerjaan, serta merumuskan rekomendasi reformasi. Penelitian menggunakan pendekatan yuridis normatif-empiris dengan analisis kualitatif. Data primer bersumber dari UU No. 11/2020, Putusan MK No. 90/PUU-XXI/2023, dan dokumen Kemnaker; data sekunder dari laporan KSPI, BPS, serta wawancara mendalam dengan 15 responden (pakar hukum UI, aktivis buruh, dan pejabat Kemnaker). Teknik analisis: deskriptif-komparatif dan content analysis. Demo KSPI mencatat 1.200+ kasus mogok kerja (2024), dipicu ketidakseimbangan hak buruh (Pasal 28 UU Cipta Kerja) versus fleksibilitas investor. Sengketa UMP 2025 menunjukkan kegagalan tripartit nasional, dengan inflasi 3,5% tidak tercermin dalam kenaikan upah riil. Konflik ini berpotensi rugi ekonomi Rp 50 triliun akibat downtime produksi. Hukum ketenagakerjaan pasca-omnibus law memerlukan reformasi melalui penguatan Dewan Pengupahan dan klausul mediasi wajib. Penelitian merekomendasikan revisi UU untuk harmonisasi hak mogok dan investasi berkelanjutan. Kata Kunci: Omnibus Law, UMP 2025, demo buruh KSPI, konflik ketenagakerjaan, judicial review MK, industrial relation, pasca-Pemilu 2024.   Abstract The revision of the Job Creation Law (Omnibus Law) via Law No. 6 of 2023 has triggered nationwide labor demonstrations, particularly the Indonesian Confederation of Trade Unions (KSPI) actions in Cikarang in 2024, coinciding with disputes over Provincial Minimum Wage (UMP) 2025 challenged at the Constitutional Court (MK). Post-2024 Election, this regulatory uncertainty threatens industrial relations stability and the 2025-2029 RPJMN economic targets. This study aims to analyze the juridical dynamics of these conflicts, identify weaknesses in labor law, and formulate reform recommendations. The study employs a normative-empirical juridical approach with qualitative analysis. Primary data are sourced from Law No. 11/2020, MK Decision No. 90/PUU-XXI/2023, and Ministry of Manpower documents; secondary data from KSPI reports, BPS statistics, and in-depth interviews with 15 respondents (UI legal experts, labor activists, and Manpower officials). Analysis techniques: descriptive-comparative and content analysis. KSPI demonstrations recorded over 1,200 strike cases (2024), driven by imbalances in workers' rights (Article 28 of the Job Creation Law) versus investor flexibility. The UMP 2025 dispute highlights tripartite mechanism failures, with 3.5% inflation not reflected in real wage increases. These conflicts risk Rp 50 trillion in economic losses from production downtime. Post-omnibus law labor regulations require reform through strengthened Wage Councils and mandatory mediation clauses. The study recommends UU revisions for harmonizing strike rights and sustainable investment. Keywords: Omnibus Law, UMP 2025, KSPI labor demonstrations, labor law conflicts, MK judicial review, industrial relations, post-2024 Election.

Abstract

Abstrak Good governance dalam dunia bisnis merupakan prinsip fundamental yang berorientasi pada terciptanya tata kelola perusahaan yang transparan, akuntabel, bertanggung jawab, independen, dan berkeadilan. Penerapan prinsip tersebut menjadi kebutuhan penting dalam menghadapi perkembangan dunia usaha modern yang semakin kompleks dan kompetitif. Dalam sistem hukum indonesia, undang-undang perseroan terbatas berperan sebagai instrumen hukum yang mengatur struktur, mekanisme, serta tanggung jawab organ perseroan guna mendukung pelaksanaan good governance dalam kegiatan bisnis. Penelitian ini bertujuan untuk menganalisis hubungan antara undang-undang perseroan terbatas dengan penerapan prinsip-prinsip good governance dalam dunia bisnis, serta mengkaji sejauh mana pengaturan dalam uu pt mampu menjadi landasan hukum bagi terciptanya tata kelola perusahaan yang baik. Penelitian ini menggunakan metode yuridis normatif dengan pendekatan perundang-undangan (statute approach), pendekatan konseptual (conceptual approach), dan pendekatan perbandingan (comparative approach). Bahan hukum yang digunakan terdiri atas bahan hukum primer, sekunder, dan tersier yang dianalisis secara deskriptif kualitatif. Hasil penelitian menunjukkan bahwa undang-undang perseroan terbatas secara substansial telah mengadopsi prinsip-prinsip good governance, terutama melalui pengaturan mengenai transparansi informasi perusahaan, akuntabilitas direksi dan dewan komisaris, tanggung jawab sosial perusahaan, independensi organ perseroan, serta perlindungan hak pemegang saham dan pemangku kepentingan lainnya. Pengaturan tersebut menunjukkan bahwa uu pt memiliki hubungan yang erat dengan upaya mewujudkan tata kelola perusahaan yang sehat, profesional, dan berkelanjutan dalam dunia bisnis. Namun demikian, implementasi good governance dalam praktik masih menghadapi berbagai kendala, seperti lemahnya pengawasan, konflik kepentingan, rendahnya kepatuhan hukum, dan budaya perusahaan yang belum sepenuhnya menjunjung prinsip tata kelola yang baik. Oleh karena itu, diperlukan penguatan penegakan hukum, peningkatan efektivitas pengawasan perusahaan, serta internalisasi nilai-nilai good governance dalam budaya korporasi agar penerapan tata kelola perusahaan yang baik dapat berjalan secara optimal dan memberikan kepastian hukum dalam dunia bisnis. Kata kunci: good governance; undang-undang perseroan terbatas; tata kelola perusahaan; hukum bisnis.   Abstract Good governance in the business sector constitutes a fundamental principle aimed at creating corporate management that is transparent, accountable, responsible, independent, and fair. The implementation of these principles has become increasingly important in response to the growing complexity and competitiveness of the modern business environment. Within the indonesian legal system, the limited liability company law serves as the primary legal instrument governing corporate structure, mechanisms, and the responsibilities of corporate organs in supporting the implementation of good governance in business activities. This study aims to analyze the relationship between the limited liability company law and the implementation of good governance principles in the business world, as well as to examine the extent to which the provisions of the company law provide a legal foundation for the realization of sound corporate governance. This research employs a normative juridical method using statutory, conceptual, and comparative approaches. The legal materials used consist of primary, secondary, and tertiary legal sources analyzed through descriptive qualitative methods. The results of the study indicate that the limited liability company law substantively accommodates the principles of good governance, particularly through regulations concerning corporate information transparency, accountability of directors and boards of commissioners, corporate social responsibility, independence of corporate organs, and protection of shareholders’ and stakeholders’ rights. These provisions demonstrate that the company law has a close relationship with efforts to establish healthy, professional, and sustainable corporate governance in the business sector. However, the implementation of good governance in practice still faces several challenges, including weak supervision, conflicts of interest, low legal compliance, and corporate cultures that do not fully uphold the principles of good governance. Therefore, strengthening law enforcement, improving the effectiveness of corporate supervision, and internalizing good governance values within corporate culture are necessary to ensure the optimal implementation of good corporate governance and to provide legal certainty in the business world. Keywords: good governance; limited liability company law; corporate governance; business law.

Abstract

The vegetable creamer-based food industry produces a large amount of waste that has not been optimally utilized, reaching more than 1.4 tons per month and accumulating up to 17 tons in a period of 10 months. Disposal of this waste also requires considerable costs, so a more sustainable alternative utilization is needed. This study aims to assess the effect of applying vegetable waste creamer solution as liquid organic fertilizer on the growth and yield of mustard greens (Brassica rapa var. Parachinensis L.). The treatments used consisted of four solution compositions: 0% (control), 10%, 30%, and 50%. Parameters observed included plant height, number of leaves, and plant wet weight. The results showed that the treatment with 10% concentration gave the most optimal results on plant height and wet weight, while the highest number of leaves was obtained from the 0% treatment. High concentrations (30% and 50%) actually inhibited growth and caused plant death. These results indicate that waste creamer has potential as a liquid organic fertilizer if used in the right composition.   Keyword: Vegetable Creamer, Industrial Waste, Organic Fertilizer

Abstract

This research is motivated by the importance of the role of Islamic Religious Counselors as agents of change in community empowerment, which until now has tended to be understood normatively and has not been studied in depth from a social perspective. This study aims to analyze the role of Islamic Religious Counselors in community empowerment in Enrekang Regency. Theoretically, this research benefits from enriching sociological studies, while practically, it serves as evaluation material for policy makers. This research uses a descriptive qualitative approach with a case study design conducted at the Ministry of Religious Affairs Office in Enrekang Regency for three months. The main instrument is the researcher with the support of interview guidelines, observation, and documentation. Data were collected through in-depth interviews, participatory observation, and documentation using primary and secondary data sources. Data analysis uses the Miles and Huberman model, while data validity is tested through triangulation and member checking. The results show that Islamic Religious Counselors play a role as facilitators, mediators, and motivators in community empowerment through a participatory and contextual approach. The implications of this research emphasize the importance of strengthening the capacity of counselors and institutional support to increase the effectiveness of their role in encouraging sustainable social change.

Abstract

Purpose – Teacher competency assessments often emphasize technical performance and administrative compliance while paying limited attention to ethical and religious value frameworks that shape professional identity in faith-based schools. In Muhammadiyah education, Al Islam and Kemuhammadiyahan (AIK), integrating Islamic teachings and institutional values, guides teachers’ professional conduct and educational practice. However, these values have rarely been operationalized within empirically validated teacher competency frameworks. This study develops and validates a teacher competency assessment model integrating AIK values into professional standards for Muhammadiyah elementary school teachers. Design/methods/approach – This research employs a research and development framework with a sequential mixed methods design, combining qualitative exploration, expert validation, and quantitative testing involving 343 teachers. AIK values were translated into observable behavioral indicators across four competency domains: pedagogical, professional, social, and personality. Psychometric evaluation assessed content validity, internal consistency reliability, and construct validity using factor-based model testing. Findings – The final instrument comprises 30 items representing the four competency domains integrated with AIK values. Results demonstrate strong content validity and high reliability, with composite reliability ranging from 0,787 to 0,893. Construct validation shows acceptable model fit (RMSEA = 0,074; SRMR = 0,073), supporting the structural coherence of the AIK integrated competency model. Research implications/limitations – This study offers an empirically grounded framework linking Islamic educational values with psychometric assessment, although broader cross-regional validation is recommended. Originality/value – This research bridges Islamic educational philosophy with contemporary psychometric practice and provides a model for value-embedded competency assessment applicable to other faith-based or culturally specific educational contexts.

Abstract

Zakat produktif sebagai instrumen pemberdayaan ekonomi Islam bertujuan meningkatkan kemandirian mustahik secara berkelanjutan, di mana kualitas peran amil menjadi faktor penentu keberhasilan setiap tahapan pemberdayaan.Penelitian ini bertujuan menganalisis peran amil dalam pemberdayaan ekonomi mustahik melalui penyaluran zakat produktif di BAZNAS Kabupaten Jember, sekaligus mengidentifikasi langkah-langkah optimalisasi peran amil yang dilakukan oleh BAZNAS kabupaten Jember. Penelitian menggunakan pendekatan kualitatif melalui wawancara mendalam, observasi, dan dokumentasi, dengan informan terdiri dari amil BAZNAS Kabupaten Jember dan mustahik penerima zakat produktif. Hasil penelitian menunjukkan bahwa amil BAZNAS Kabupaten Jember telah menjalankan peran fasilitatif, edukatif, dan representatif sesuai teori peran pekerja sosial Jim Ife. Namun, peran teknis belum optimal akibat tidak adanya mekanisme pelaporan perkembangan usaha mustahik yang sistematis. Untuk mengoptimalkan peran amil di tengah keterbatasan sumber daya, BAZNAS mengembangkan dua strategi yakni pembagian wilayah menjadi empat zona geografis dengan rotasi monitoring terstruktur, serta penggabungan kegiatan monitoring dan penyaluran bantuan untuk efisiensi operasional. Penelitian ini menyimpulkan bahwa penguatan peran teknis amil melalui sistem pelaporan yang lebih terstruktur merupakan langkah krusial agar pemberdayaan ekonomi mustahik melalui zakat produktif dapat berjalan secara optimal dan berkelanjutan.

Abstract

Introduction: Nanoparticles ranging from 1-100 nm in diameter can be synthesized using green synthesis methods, which utilize environmentally friendly, non-toxic, economical, and easily manageable resources to promote sustainable nanotechnology development. Pegagan contains saponins, triterpenoids, flavonoids, and tannins that serve as antioxidants for the skin, offering anti-inflammatory and anti-aging benefits. This study aims to synthesize and characterize gold nanoparticles using pegagan leaf extract, and evaluate its potential as an inhibitor of the tyrosinase enzyme involved in melanin formation in human skin. Methods: Synthesis was conducted by mixing HAuCl4 at a concentration of 2 mM with liquid extract of pegagan leaves. The synthesized products were characterized using UV-Vis spectrophotometer, spectrofluorometer, and Particle Size Analyzer to observe the characteristics of the formed nanoparticles. Additionally, the inhibition activity of the tyrosinase enzyme was tested using a microplate reader at a maximum wavelength of 490 nm. Results: During the synthesis of gold nanoparticles, there was a color change in the solution from yellow to purple. Measurements using UV-Vis spectrophotometer showed a spectrum with a peak wavelength at 533 nm, but no fluorescence was observed. Gold nanoparticles measured using PSA ranged in size from 24.36 to 91.28 nm. The inhibition activity test of the CA-AuNPs solution yielded an IC50 of -2,286.202 µg/ml, while the positive control solution using kojic acid showed an IC50 of 31.615 µg/ml. Conclusion: Gold nanoparticles can be synthesized using pegagan extract as a reducer, but they do not exhibit potential as inhibitors of the tyrosinase enzyme.
