Penelitian ini bertujuan untuk mem-validasi hasil eksperimen pada uji ketangguhan retak material paduan aluminium di bawah pembebanan dinamik dengan simulasi atom. Model retakan yang digunakan adalah material Alumunium dengan orientasi atom [111], [110], dan [112] dengan jumlah atom 17.402 dan kondisi batas periodik untuk mempresentasikan kondisi regangan bidang. Hasil yang diperoleh menunjukkan beberapa dislokasi yang dipancarkan dari ujung retak, nukleasi dan pertumbuhan lubang kecil (micro void) terjadi di depan ujung retak. Lubang kecil dimulai dari inti dislokasi saat beban dijaga konstan yang tidak pernah bersatu dengan retak utama karena jarak antara lubang kecil dan celah utama terlalu jauh secara atom dan pertumbuhan lubang menjadi stabil. Validasi secara kualitatif dapat diberikan oleh simulasi atom ini.

Every organization have a goal. In the digital era, organization use automated information technology to process their information for better support for their goals, and risk management plays and important role to protect information assets of organization and for that purpose can be accomplished. An effective risk management process is an important component of the success of information technology security program. The principle objectives of an organization’s risk management should be protect organization and the ability to perform their purpose is not to protect information technology assets only. For this risk management process should not be treated purely as a function but the technique is the basis of the management functions of the organization.

Penggunaan pipa PVC dalam kehidupan sehari-hari untuk memenuhi kebutuhan air bersih telah menjadi kebutuhan yang tidak bisa diabaikan. Selain karena kemudahan dalam instalasi, pipa PVC juga dikenal kuat dan mempunyai daya tahan di lingkungan indoor dan outdoor. Walau demikian pipa PVC mempunyai batas kekuatan akan tekanan yang bekerja terutama dalam varian elbow PVC. Dalam tulisan ini penulis akan mencoba analisa perbandingan (rasio) kerugian aliran air perhitungan manual pada elbow dengan perhitungan menggunakan Computational Fluid Dynamics dengan variasi spasing mesh dan mode perhitungan. Kata kunci: pipa pvc, elbow, software, meshing

Kebutuhan Hidrogen sebagai solusi dari Sistem Energi Baru dan Terbarukan dari tahun ke tahun semakin meningkat. Indonesia yang berada di daerah katulistiwa dan sebagian besar wilayahnya berupa kepulauan mempunyai potensi yang sangat besar dalam menghasilkan hidrogen. Menjadi tantangan bagaimana kita dapat memanfaatkan hal tersebut dengan salah satu cara memproduksi hidrogen yang di integrasikan dengan pembangkit listrik tenaga air (Hydro Power) dengan varian teknologi elektrolisis yang tersedia. Hidrogen yang diproduksi oleh hydro-power dapat langsung digunakan dalam sistem pembangkit Fuel Cell, sehingga dapat menghasilkan listrik lebih besar. Penelitian dan pengembangan prototype jenis-jenis fuel cell sangat diperlukan untuk meningkatkan daya saing kita sebagai bangsa. Pemanfaatan sensor dan teknologi informasi dalam meningkatkan optimalisasi kerja fuel cell menjadi kebutuhan dalam era revolusi industri 4.0.

A steam power plant (PLTU) uses demin water to generate 3x350 MW of electrical energy. Reverse Osmosis Desalination system is used to treat the 190 m3/hour of desalinated water that is produced from seawater. Solar energy will replace the 225.41 kW of electrical energy required for the RO desalination pump in order to lessen pollution and the greenhouse effect caused by PLTU. The PLTU is situated in Pelabuhan Ratu Sukabumi, West Java. This region has a solar radiation potential of 3.189 kWp/day/m2 and a deployment space for PV modules of 6,167 m2, divided into two zones: the ground and the roof. The needs analysis is carried out by utilizing software simulations that estimate the power requirements of desalination pumps and the potential of electrical energy from solar radiation based on land availability. According to the modeling findings, PLTS can produce 1024 MWh/year of electrical energy with 1,458 pieces of 450 Wp PV modules and 5 units of 120 kW inverters.

Children who are in conflict with the law, even though they are suspectedof having committed a criminal act, still have the right to protection by the state,especially regarding their identity. The Supreme Court Decision Directory as asite that contains information about Supreme Court decisions, including asummary of decisions, legal considerations, and links to complete decisionsshould pay attention to the importance of not publishing the identity of children inconflict with the law when uploading copies of decisions. Publication of theidentity of children in conflict with the law can have a very bad impact onchildren, such as stigmatization and discrimination which can affect their future.The type of research used in this research is normative juridical legalresearch or can also be called doctrinal legal research. Normative juridical legalresearch is library legal research. The research uses qualitative analysis whichproduces descriptive data.From the results of this research, there are several main things that can beconcluded. First, the Law on the Juvenile Justice System stipulates that theidentity of children in conflict with the law must be kept confidential, both in printand electronic media, but in reality there are still many decisions that do notobscure the child's identity before being uploaded to the Supreme Court DecisionDirectory website. such as decision Number 18/Pid.Sus-Anak/2021/Pn Srg whichexplicitly shows the identity of the child as the perpetrator, the name of theparents, and the place of residence where the decision can be accessed by thepublic. Second, the Supreme Court Directory's information officer's mistake inpublishing a copy of the child's decision may result in administrative sanctions,but in enforcing these sanctions it does not provide a deterrent effect so thatcriminal regulations as an ultimum remedium or as a final resort in lawenforcement are expected to provide a deterrent effect for Directory officers. TheSupreme Court is responsible for the case.Keywords: Publications, Child Identity, Supreme Court Directory.
