The purpose of this study was to (1) analyze the characteristics of fresh concrete with the addition of coconut shell waste (2) to analyze the compressive strength of concrete with the addition of coconut shell. The research location for making concrete was carried out at the Laboratory of the construction of the water resources and community development department of the Southeast Sulawesi provincial government. There were 24 specimens printed in the form of a cylinder with dimensions of 30cm x 15cm with the composition of adding 0%, 5%, 10%, and 15% coconut shell waste. Which was then tested for compressive strength at the age of 7, 14, and 28 days. Based on the compressive strength test with a quality plan of f'c 20 MPa, on the 28 day test with the addition of 0% is 23.71 MPa, the addition of 5% is 20.59 MPa, the addition of 10% is 19.97 MPa, and an additional 15% is 13.53 MPa. Coconut shell as a substitute for coarse aggregate for quality f'c 20 MPa can only be used under 10% of the amount of coarse aggregate.

The development of road infrastructure in Indonesia is currently increasing, starting with new road construction projects to road improvement projects. To prevent premature damage to road pavements due to loading and the influence of water, it is to improve the quality of asphalt as a binder material from aggregate in the composition of road pavements. especially for the Asphalt Concrete-Binder Course (AC-BC) mixture, the addition of human hair waste can be used as an added material to minimize the use of asphalt and overcome the weaknesses of asphalt and waste utilization.The objectives of the study were: (1) to analyze the characteristics of the modified asphalt mixture with the addition of human hair waste. (2) Analyzing the performance of modified asphalt mixture with the addition of human hair waste.The results of analysis and testing in the laboratory show that the modified asphalt mixture performance with the addition of hair will increase the density value up to 2,355 gr/cc, increase the stability value up to 1886,2 kg, increase the value of the asphalt filled cavity (VFB) up to 82.8% and increase the Marshall value. Quotient (MQ) up to 653.3 kg/mm, but will reduce the value of the melt (flow) up to 2.9 mm, reduce the value of voids between mineral aggregates (VMA) up to 15.8% and reduce the value of mixed air voids (VIM) up to 2.7% but still within the threshold of meeting specifications

Development in the field of structure is currently progressing very rapidly in various field so that concrete is one of the choices as a structural material in building construction, basically concrete is made by mixing portland cement, coarse aggregate, fine aggregate, and water as a binder for these materials. Due to the development of the issue of current resource limitations, the prevention is by innovating the manufacture of concrete using palm fiber waste as an added ingredient from sand and rice husk ash waste as an added ingredient from cement. The purpose of study was to (1) analyze the compressive strength of concrete with variations ini rice husk ash and palm fiber (2) analyze the addition of rice husk ash and palm fiber with different mixture variations that could affect the compressive strength of concrete. The result showed that normal concrete with an average compressive strength of 24.20 MPa and an increase in compressive strength with a mixture of 0.5% palm fiber and 5% rice husk ash with an average strength of 25.90 MPa without using superplasticizer, if the variation mixture exceeding the mixed variation of 0.5% palm fiber and 5% rice husk ash will deacrease

Indonesia yang telah memasuki era revolusi industri 4.0 yang menyebabkan penggunaan internet dan tehnologi digital terus berkembang pesat dalam kehidupan sehari hari. Di usia 15-17 tahun juga sudah menjadi usia yang cukup bagi mereka untuk memahami bagaimana mengakses internet untuk kebutuhan pendidikan, hiburan bahkan bersosialisasi dengan orang lain. Dengan pemahaman yang baik dalam mengakses internet ini, kadang mereka melupakan bahwa ada norma dan etika tersendiri di dalam penggunaan internet. Para remaja di SMA Swasta Iskandar Muda Aceh Utara tentunya sudah tidak asing dengan dunia digital. Pihak sekolah juga telah berupaya untuk mengedukasi peserta didik dalam etika digital. Namun demikian, pembahasan mengenai konsep Netiket atau Net Etiket atau Etika Digital belum dijelaskan secara detil dan terperinci di dalam muatan materi di sekolah. Maka dari itu yang manjadi permasalahan dalam pengabdian ini adalah bagaimana menimbulkan pemahaman dari minimnya pengetahuan remaja tentang penerapan digital etik dalam menggunakan sosial media. Kurangnya pemahaman mitra terkait dampak yang ditimbulkan dari penggunaan media sosial yang tidak menggunakan digital etik. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman para peserta didik yakni siswa SMA Swasata Iskandar Muda terhadap etika digital, sehingga berkontribusi dalam menumbuhkan tingkat kesadaran hukum bagi remaja, serta melakukan analisis terhadap jenis dan dampak dari penggunaan mendi sosial yang tidak mengedepankan digital etik. Metode yang digunakan dalam pelaksanaan pengabdian kepada masayarakat ini adalah dalam bentuk penyuluhan hukum berupa pemaparan materi dari narasumber serta diskusi tanya jawab dari peserta penyuluhan tentang pentingnya memahami digital etik dan perlunya menerap etika dalam bersosial media. Hasil yang di dapatkan dari pengabdian ini adalah siswa mengetahui bagaimana harus menghadapi orang-orang yang sudah terlanjut salah dalam menggunakan media sosial, siswa mengetahui sikap yang harus dilakukan apabila berada di lingkungan Sosial media. Siswa mengetahui perilaku baik dan buruk yang sepatutnya dihindari agar tidak terjerumus ke pengguanaan sosial media negatif. Siswa juga memahi aturan yang terkait dengan informasi dan teknologi baik dalam hukum nasional. Kegiatan pengabdian masyarakat di SMA Swasta Iskandar Muda Aceh Utara berjalan dengan baik dan mendapat respon positif dari para peserta. Penyuluhan ini merupakan suatau upaya preventif dalam mencegah para siswa/I kejahatan dimedia sosial dan menjadi jalan untuk meningkatkan kesadaran hukum bagi siswa/I dalam menggunakan media sosial.

This bibliometric analysis explores the scope and dynamics of Internet of Things (IoT) research with a focus on energy efficiency, environmental impact, and resource management. Using data sourced from Scopus and visualized through VOSviewer, the study maps out the evolution of research themes, highlights interdisciplinary collaboration, and discusses the integration challenges and policy implications of IoT technologies. The analysis identifies a significant shift from foundational technological issues to applications that enhance sustainable development and address global energy demands. Despite challenges such as implementation costs, security concerns, and environmental impacts associated with IoT devices, the potential of IoT in promoting energy efficiency and sustainability is profound. The study also emphasizes the need for robust policies and international cooperation to fully leverage IoT benefits in addressing environmental and energy management challenges. Future research directions are suggested to further explore the integration of IoT with renewable energy sources and to enhance the sustainability of IoT systems.

The principal plays an important role in influencing and directing existing school personnel. This is done so that the plans that have been determined can be carried out by involving all elements (cooperating) in achieving school goals. Teacher performance in the form of carrying out the task of educating students is determined by work motivation. Therefore, effective principal leadership can influence teacher work. This study aims to determine the effectiveness of the principal's leadership in managing conflicts that occur in SMPN X Banjar, South Kalimantan. This study uses a qualitative paradigm. While the approach is a case study. Methods of data collection using observation, interviews, and documentation studies. The results of the study show that democratic principal leadership (having principal competence) is able to minimize conflicts that occur within the school environment.
