The need for digitally scanned documents has become a public need these days. Furthermore, smartphone usage with supporting applications to scan barcodes and documents digitally has become a trend. The problem that often occurs when scanning documents is the instability of the hand-held document. In addition, the 3-axis coordinate determination of a smartphone is also not easy to control. Therefore, tools are needed to speed up and simplify the scanning process. This research aims to create a tool that can increase work productivity when scanning documents using a smartphone. Market analysis, engineering planning, and prototypes have been carried out to learn what will decide mass production and sale in general. The data analysis method used a full factorial design, using gender as a factor and preparation time and data scanning time as levels. The initial preparation time to retrieve photo and PDF documents from the initial preparation and scanning results on average takes 4.357 minutes with Std. Deviation 1.739 minutes. As for the following scan with the same paper size, it only takes 1.242 minutes with Std. Deviation 0.201 minutes. The production cost of this prototype is 126.22USD with Std.Deviation 11.36USD. Even though the production cost is the highest, it has a TKDN value of 100% and the application of PBL by students who can carry it out well.

The working principle of CNC Milling machine is the machine rotates and contacts with the workpiece so that erosion and cutting occur. The machining process affects the mechanical properties of the material, so it needs to conduct a study to determine changes in the character of the material due to the machining process. This research was conducted to determine the effect of the number of 2 flutes and 4 flutes on the workpiece surface roughness using PMC-5VT20 CNC Milling machine. Specimens test use 304 material stainless steel that has strength and resistance to the corrosive. The research method was carried out experimentally using 304 stainless steel material which had been done with a finishing process using an endmill cutter with 2 flutes and 4 flutes. The roughness of specimens were tested using surface roughness tester to determain the effect of flute number on the surface roughness. The result of testing shows that the number of flutes affects the roughness of the machining process. The roughness value using 2 flutes is lower than the use of 4 flutes.

Molding is a process utilized by industries to shape plastic products. One of the plastic molding processes involves injection molding. Injection molding is a procedure where plastic pellets are placed into a hopper or channel and subsequently fed into a barrel. The injection is propelled by a screw mechanism through a machine nozzle and a sprue bushing enters the mold cavity. All of this occurs within a closed mold. A flashing defect in a product refers to an excess material flaw located at the product's edges. To identify the causes of flashing defects in shaving tools, a fishbone diagram is employed, categorizing factors into five: machine factors, material factors, method factors, human factors, and mold factors. The identification results show that flashing defects in shaving tools are primarily attributed to mold factors, where 37 cavities exhibit flashing defects.

The objective of this study is to assess the influence of utilizing flashcards on vocabulary mastery among sixth-grade students at SDN 1 CISANGU. The research methodology employed was a pre-experimental design involving a one-group pretest-posttest approach. The sample size consisted of one class comprising a total of 26 students. The data for this study were derived from the pretest and posttest results, which were conducted in the format of written tests. The data analysis process involved utilizing the t-test formula. The results of this study for the t-test obtained t arithmetic t table or 5,956 >1,708 then H0 is rejected and H1 is accepted. Thus, it can be concluded that there is an influence of flashcard media on the vocabulary mastery of sixth-grade students of SD Negeri 1 Cisangu. The N-gain test with a result of 0.68 is in the medium category, which means that the utilization of the use of flashcard media is influenced by vocabulary mastery.

Penelitian ini bertujuan untuk mengetahui bagaimana bentuk pertanggungjawaban notaris terkait adanya dugaan pidana menempatkan keterangan palsu dalam akta authentik dan bagaimana pertanggungjawaban pidana bagi penghadap yang membuat keterangan palsu dalam pembuatan akta yang dibuat oleh notaris. Jenis metode penelitian yang digunakan penulis adalah metode penelitian hukum normatif yang disebut juga dengan penelitian yuridis teoritis atau penelitian hukum doktrinal karena tidak mengkaji pelaksanaan atau implementasi hukum. Penelitian ini dilakukan dengan cara mengkaji bahan-bahan pustaka, perundang-undangan dan putusan pengadilan berkaitan dengan permasalahan yang akan dikaji. Sebagaimana telah diatur dalam Yurisprudensi Putusan Mahkamah Agung No. No.702K/Sip/1973 Keterangan palsu yang disampaikan oleh para pihak adalah menjadi tanggung jawab para pihak. Hasil penelitian ini menunjukkan bahwa yang dapat diminta pertanggungjawaban pidana kepada notaris adalah apabila perbuatan pidana seperti penipuan atau tipu muslihat itu bersumber dari notaris sendiri. Namun apabila keterangan palsu dituangkan dalam akta autentik atas keterangan penghadap tanpa diketahu kepalsuannya oleh notaris maka pertanggungjawaban pidananya dikenakan pada penghadap dan tidak dapat dikenakan pada notari.

The digital transformation in education has encouraged the adoption of computer-based tests (CBT) using video content, which demands stable and efficient network performance. This study aims to evaluate the performance of two queue management algorithms, namely Random Early Detection (RED) and Per Connection Queue (PCQ), in maintaining the quality of service (QoS) of school networks during online video-based examinations. A case study approach was applied using a real network topology in a school environment, and QoS parameters such as throughput, delay, packet loss, and jitter were measured. The implementation was conducted using a MikroTik RB450Gx4 router configured with simple queue settings for each algorithm. The results show that PCQ provides more consistent performance under high user loads, achieving an average throughput of 56,482 bps and lower delay compared to RED. Conversely, RED performs better in scenarios with a small number of users. The study recommends using PCQ for networks with dynamic and dense user environments, while RED is more suitable for low-traffic conditions where latency stability is crucial. These findings offer practical guidance for managing bandwidth and improving the quality of CBT delivery in educational settings.

This research aimed to investigate non-English major students’ perceptions of mobile language applications in supporting their autonomous learning. 36 non-English major students from the Faculty of Economics and Business at Universitas Sultan Ageng Tirtayasa participated in this research. Quantitative and qualitative methods (mixed methods) were used to conduct the study. By implementing an explanatory sequential design with a Likert scale questionnaire and semi-structured interviews, the research data were collected. The quantitative data were analyzed using descriptive statistics, and the qualitative data were analyzed based on Miles and Huberman’s theory. The Data Analysis feature of Microsoft Excel was also employed to process the quantitative data. The results showed that the Duolingo application is the most frequently used mobile language application by non-English major students; 91.7% (33 non-English major students) chose this app. They also expressed positive perceptions of using mobile language applications to support their autonomous learning, despite several challenges and technological limitations, such as poor internet connections, lack of interaction, and restrictions in the free features. Moreover, non-English major students reported in the interviews that mobile language applications often provide only brief explanations or feedback, and the lack of interaction and supervision can sometimes lead to reduced motivation to learn. Therefore, it can be concluded that technological advancement cannot replace the role of English teachers in providing detailed explanations, motivation, and emotional support to learners
