The research aims to determine the effect of wound care education using virtual reality media on wound care knowledge among patients' families. This study used a pre-experimental design with a one-group pre-test-post- test. The sample was 32 respondents from families of patients with post-operative wounds. The sampling technique used purposive sampling. The research instrument used a wound care knowledge questionnaire developed from standard wound care operating procedures. The results were analyzed using the marginal homogeneity test. The level of knowledge before education was mostly inadequate for 20 respondents (62.5%), and after education, it increased to sufficient for 22 respondents (68.75%). The marginal homogeneity test yielded a p-value of 0.000, indicating an effect of wound care education using virtual reality on wound care knowledge among patients' families. Education using virtual reality effectively improved wound care knowledge among patients' families.

Muhammad Kurniawan — 2026-03-10

This research aims to design and realize a prototype of a coconut milk machine based on Outseal PLC that integrates the grating and squeezing processes in one automatic system. The system uses Outseal Mega V.2 PLC as the main controller with Arduino Uno support for sensor reading. A load cell sensor is used to detect the weight of 1 kg of grated coconut as a parameter for the process transfer to the squeezing stage. The test results show that 1 kg of grated coconut produces approximately ½ liter (500 ml) of coconut milk. An ultrasonic sensor is used to detect the height of the coconut milk surface in the container, which is approximately 14.8 cm at a volume of 500 ml as the system's stop limit. The process of making coconut milk using the machine takes approximately 40 minutes, faster than the manual process which takes approximately 60 minutes. The results of the study indicate that the tool is able to increase time efficiency and reduce manual work processes in making coconut milk.

KOMUNIKASI MASSA DALAM PROGRAM NTV MORNING: RESPONS STASIUN TV NTV TERHADAP TANTANGAN KONVERGENSI MEDIA

Suardin Ndruru — 2026-03-10

The transformation of digital technology has fundamentally changed the pattern of mass communication, from a one-way linear model to a two-way interactive model. This change requires broadcasters not only to convey information through television broadcasts but also to be able to adapt to the behavior of digital audiences who access information through various online platforms. In this context, Nusantara TV, through its NTV Morning program, faces the challenge of media convergence, which requires the integration of technology, content, and distribution strategies across channels. This study aims to analyze how the NTV Morning program responds to the challenges of media convergence through the implementation of a multiplatform production strategy. The study uses a qualitative approach with data collection techniques such as observation, in-depth interviews, documentation, and triangulation. The research informants consist of three key parties directly involved in the production of the NTV Morning program. The study found that the production process of the NTV Morning program takes place in three main stages: pre-production, production, and post-production, which are carried out simultaneously and collaboratively. This program implements the convergence of technology, content, and industry, and develops a distribution strategy based on an analysis of digital trends and audience preferences on television, YouTube, TikTok, Instagram, WhatsApp Channel, Facebook, and X (Twitter). NTV Morning not only upholds the principles of conventional journalism but also integrates one-way and two-way mass communication practices. This makes the program an adaptive news production model relevant to the digital media ecosystem.

Pengaruh Campuran Fly ash dan Variasi Kapur terhadap Daya Dukung Tanah Bekas Tambang di Gunung Sarik

Ereza Apriyani — 2026-03-13

The limited availability of land suitable for development has encouraged the utilization of alternative land, one of which is ex-mining land. Soil in ex-mining areas generally has low bearing capacity and therefore does not meet the technical requirements for construction subgrade. This study aimed to analyze the effect of adding fly ash and lime on increasing the bearing capacity of ex-mining soil in Gunung Sarik Village, Kuranji District, Padang City. The soil damples used were disturbed soils collected from the ex-mining area. Fly ash was obtained from the Teluk Sirih Steam Power Plant, West Sumatra, while quicklime was sourced from the Bukit Tui Factory, Pdang Panjang City. The research was conducted through laboratory testing including physical properties analysis, Proctor compaction test, and California Bearing Ratio (CBR) laboratory testing based on ASTM D 1883-67 standards. The mixture variations consistes of 5% fly ash combined with 0%, 4%, 8%, and 12% lime. The addition of fly ash and lime positively influenced the increase in soil bearing capacity. The CBR value of native soil, Which was 10,37%, increased across all mixture variations. The highest increase was achieved with the combination of 5% fly ash and 12% lime, reaching a CBR value of 19,16%, followed by the mixture of 5% fly ash and 8% lime at 14,43%, and 5% fly ash with 4% lime at 14,21%. These results indicate thet the addition of fly ash and lime is effective in increasing the bearing capacity of ex-mining soil through the stabilization process, making the soil feasible for consideration as construction subgrade.
