Pada tambang terbuka batubara di daerah penelitian air tanah sengaja di dewatering untuk kestabilan lereng tambang dan tidak mengganggu pekerjaan, sehingga diperkirakan akan menurunkan zona jenuh air tanah. Tujuan penelitian ini yaitu untuk mengetahui lapisan batuan dan perubahan zona jenuh air tanah. Untuk mengetahui hal tersebuttelah dilakukan penelitianmenggunakan metode geolistrik resistivitas konfigurasi Wenner di dua lintasan dengan dua kali pengukuran (September 2011 dan Mei 2012). Dari hasil pengolahan data menggunakan Software Res2Dinv daerah penelitian tersusun dari batuan dengan resistivitas 0,72-21,7 ohm meter yaitu batuan lempung yang diperkirakan merupakan batuan zona jenuh dan batuan lainnya dengan resistivitas 21,8-2064 ohm meter yang terdiri dari batuan lempung pasiran, pasir, serta sisipan batubara. Penurunankedalaman lapisan zona jenuh air tanah berkisar 0,5-2,0 meter dan penipisan ketebalan 0,5-13,5 meter.

The international growth strategy has become increasingly important for small and medium-sized enterprises (SMEs) to enhance competitiveness and expand their market in the era of globalization. SMEs that want to start international expansion must consider several key factors, such as choosing the right products and markets, understanding legal requirements and regulations in the target country, selecting appropriate systems, and building a strong business network. There are also strategic steps that must be taken to improve the growth of small and medium-sized businesses. This research uses a literature review method by examining relevant journals related to the International Growth Strategy for Small and Medium Enterprises. The research is expected to increase knowledge and application in the business world for small and medium-sized enterprises

Pelatihan literasi digital di Desa Cipanas bertujuan untuk meningkatkan kesadaran masyarakat mengenai pentingnya perlindungan informasi pribadi dan penggunaan teknologi digital secara aman. Kegiatan ini diikuti oleh 46 peserta, dengan 27 di antaranya mengisi kuesioner evaluasi. Hasil evaluasi menunjukkan bahwa sebagian besar peserta telah memahami konsep dasar informasi pribadi dan menyadari pentingnya langkah-langkah perlindungan dalam era teknologi informasi modern. Sebagian besar peserta juga melaporkan menggunakan kata sandi yang berbeda untuk setiap akun online mereka serta menerapkan langkah keamanan tambahan, seperti verifikasi dua langkah. Namun, hanya sedikit peserta yang mengetahui keberadaan undang-undang perlindungan informasi pribadi di Indonesia, dan banyak di antaranya jarang membaca syarat dan ketentuan layanan digital. Berdasarkan temuan ini, tim pengabdian masyarakat merekomendasikan pengadaan pelatihan lanjutan yang berfokus pada privasi digital dan keamanan teknologi, serta menyarankan penyelenggaraan seminar dan pelatihan rutin untuk meningkatkan edukasi masyarakat secara berkelanjutan.

Mangrove ecosystem is a coastal wetland has biodiversities such as flora, fauna, and microorganisms. Microorganisms are an importants component in the mangrove ecosystem and have many roles, including source the nutrition, decomposer, and a source of biotechnology products. Cellulolytic bacteria are a group of cellulase-producing bacteria capable of breaking down cellulose into glucose monomers. This study aims to screen and determine the diversity of cellulolytic bacteria from the mangrove ecosystem. The research method has been experimental by exploring the cellulolytic bacteria in soil and sediment from the mangrove ecosystem. Three sampling locations were selected such as the litter soil, soil in the root, and soil in the tidal area. The screened of potential bacteria-producing cellulase was obtained by bacteria growth on Carboxy Methyl Cellulose (CMC) agar medium. The isolates were cultured for 48 hours at 37°C. Then, the bacteria that produced the cellulolytic activity were characterized by morphological and physiological characteristics. The results were adjusted according to Bergey's Manual of Determinative Bacteriology. The determination showed that six isolates had the same characteristics as Bacillus, Cellulomonas, Lactobacillus, and Micrococcus. The cellulolytic activity index showed that three isolates were sequentially MS06 (9,73), MS03 (6,30), and MS08 (5,41).

This research aims to explore and analyze the reformulation of school management strategies in improving the digital competence of teachers in private high schools. Digital competence is an urgent need in the era of educational transformation, especially for teachers as the main actors in the learning process. This study uses a qualitative approach with a case study design on two private high schools located in the Magetan area. Data were collected through in-depth interviews, participatory observations, and documentation studies, analyzed using the Miles and Huberman model which included data reduction, data presentation, and conclusions drawn. The results of the study show that private schools that implement HR strategies in a planned and contextual manner ranging from digital skill-based teacher recruitment, continuous training, digital platform-based performance evaluation, to providing digital innovation-based incentives are more successful in improving teacher competence. The transformational leadership of the principal is a key factor in the success of the strategy. These findings confirm the importance of a comprehensive school management reformulation to support the successful digital transformation of education in private secondary schools. This research provides theoretical and practical implications for school and foundation management in designing digital needs-based human resource strategies.

Pesatnya pertumbuhan sepeda motor di Indonesia telah membawa dampak signifikan terhadap keselamatan lalu lintas, terutama dengan meningkatnya angka kecelakaan akibat perilaku berkendara berisiko. Salah satu upaya mengontrol perilaku ini adalah melalui legalitas surat izin mengemudi (SIM) yang bertujuan memastikan pengemudi memiliki kompetensi yang memadai. Namun, sistem penerbitan SIM di Indonesia sering kali masih menghadapi tantangan berupa praktik percaloan yang memungkinkan pengemudi memperoleh SIM tanpa melalui prosedur resmi yang mencakup ujian kelayakan sesuai aturan. Penelitian ini bertujuan untuk mengevaluasi pengaruh legalitas SIM terhadap perilaku berkendara berisiko dan mengidentifikasi faktor-faktor lain yang relevan menggunakan kerangka extended theory of planned behavior (TPB). Dengan melibatkan 355 responden yang dipilih melalui purposive sampling, data dianalisis menggunakan partial least squares structural equation modeling (PLS-SEM) untuk unigroup dan multigroup. Analisis unigroup dilakukan pada satu kelompok sampel. Analisis multigroup dilakukan pada dua atau lebih kelompok sampel terpisah untuk membandingkan apakah model analisis atau hubungan di antara variabel berbeda secara signifikan antar kelompok tersebut. Hasil menunjukkan bahwa tidak ada perbedaan signifikan antara kelompok yang memperoleh SIM melalui jalur resmi dan calo dalam memengaruhi perilaku berkendara berisiko. Namun, variabel kebiasaan berkendara (KB), niat berkendara (NB), kontrol perilaku (KP), dan sikap (SK) tetap memiliki pengaruh signifikan terhadap perilaku tersebut, di mana kebiasaan berkendara menjadi faktor dominan. Temuan ini menekankan perlunya reformasi sistem penerbitan SIM dan penguatan pendidikan keselamatan berkendara untuk mewujudkan pengendara yang lebih bertanggung jawab dan mengurangi risiko kecelakaan.
