In this sense, advertisements are understood not merely as marketing strategies, but as communicative practices embedded with ideology. Through the messages they convey, the ads promote values of efficiency, frugality, and modernity, which ultimately influence the construction of consumer identity and behavior. The study applies Norman Fairclough’s Critical Discourse Analysis framework, which consists of textual analysis, discursive practice, and socio-cultural context. This approach allows researchers to explore how language in advertisements contributes to the construction of social reality, communicates particular perspectives, and encourages audiences to respond actively.

In recent years, the Indonesian government has actively promoted digital transformation in public service delivery, including in rural and remote areas. However, digital adoption among communities in these regions remains inconsistent and often hindered by infrastructural and socio-cultural constraints. This study aims to assess the digital readiness of rural communities in adopting mobile-based public service information systems, with a specific focus on understanding the social and technological dynamics that shape their engagement. Employing a mixed methods approach with an explanatory sequential design, the research began with a structured survey involving 150-200 respondents per location, followed by in-depth interviews with key informants such as village officials, service operators, and local users. The quantitative data were analyzed using SPSS to identify general patterns in digital readiness based on the Technology Readiness Index and the Digital Readiness Framework, while qualitative insights were thematically analyzed using NVivo to uncover contextual factors. The findings reveal that while some respondents exhibit a moderate level of digital optimism, barriers such as unstable internet access, limited digital literacy, and fear of misusing technology significantly affect adoption rates. Furthermore, social support from family members emerged as a critical facilitator in overcoming these challenges. This study contributes to the discourse on inclusive digital transformation by highlighting the importance of integrating community-based support mechanisms into system design and policy planning. The implications suggest that successful digitalization efforts in rural areas must go beyond infrastructure development and address the social readiness of users through culturally sensitive and participatory approaches.

This article is a literature review that examines Paul Ricoeur’s concept of narrative identity and its relevance to education. Ricoeur conceives human identity as a dynamic construction shaped through narrative, namely the reflective interpretation of life experiences within the dimensions of time, social relations, and self-awareness. In this framework, education is not merely understood as a means of knowledge transmission but also as a hermeneutical space where learners construct an understanding of themselves through experience, reflection, and dialogue. Narrative enables students to coherently connect the past, present, and future, while simultaneously cultivating character, responsibility, and empathy. This article highlights the importance of narrative-based learning strategies, such as case studies, autobiographical writing, analysis of literary and historical texts, and project-based learning. Through these approaches, students are encouraged to develop a reflective and ethical identity that is open to diversity. Thus, Ricoeur’s thought provides a strong philosophical foundation for building humanistic character education in which learners are positioned as subjects who grow and transform through their own life stories.

This community outreach activity was conducted at the Wahyu TPQ/RA Foundation, focusing on the implementation of religious character education through daily habituation activities for early childhood.

A sump is a water reservoir that functions to accommodate runoff water in the pit before the water is pumped. This study was conducted to determine the location plan and sump capacity based on the direction of mine progress and the actual estimation of runoff discharge that enters the pit at PT. Wahyu Murti Garuda Kencana, Central Kalimantan. There is a water problem that interferes with production activities because the actual sump dimensions are insufficient to accommodate the daily discharge of water that enters the sump. So that the impact on the mining front is flooded or there is waterlogging that disrupts mining activities. The progress of the mine is directed towards the north of the sump so that the distance and dimensions of the actual sump are ineffective and unable to accommodate the incoming water discharge in accordance with the direction of the mine progress due to the mining location in the pit which is easily submerged by water. The drainage condition at PT. Wahyu Murti Garuda Kencana uses the mine dewatering method which is a method of removing water that flows into the mining sump using a pump. Theoretically, by conducting direct research on the sump area of PT. Wahyu Murti Garuda Kencana, the actual sump dimensions are insufficient to accommodate the water discharge that enters the pit. The design carried out pays attention to the mining plan so that the sump design to be designed can be applied in the field in accordance with the mine design. The shape of the sump designed is a trapezoidal shape with dimensions of 80 m x 70 m cross-section, 74 m x 64 m bottom section, depth of 4 m and 55 degree tilt angle and a total sump volume capacity of 20,672 m3.

Waste candlenut shells are one type of biomass that has significant potential to be developed as an alternative energy source, particularly in the form of briquettes. Candlenut shells, which are typically discarded as agricultural waste, contain combustible material that can be transformed into solid fuel. However, the traditional briquette molding process is still done manually, which is time-consuming, inefficient, and often results in inconsistent briquette shapes and density. This study aims to design and develop a briquette molding machine specifically for processing candlenut shell waste, with the goal of improving both production efficiency and the quality of the briquettes produced. The research methodology includes several stages: mechanical design, selection of appropriate materials, fabrication of machine components, assembly, and performance testing of the machine. The resulting machine utilizes a screw conveyor compression system powered by a 5.5 HP petrol engine. It features a cylindrical mold with a 40 mm diameter to shape the briquettes uniformly. During the performance test, the machine demonstrated a maximum production capacity of 14.3 kg per hour, with an average processing time of 24 minutes and a briquette yield reaching up to 85%. The findings indicate that the machine can significantly streamline the briquette production process while maintaining product consistency and quality. This briquette molding machine is particularly suitable for household and small-scale industries aiming to utilize renewable energy sources and reduce dependency on fossil fuels. The use of this machine also supports environmental sustainability by converting agricultural waste into a usable energy product.  

Climate change and air pollution are necessitating a transition towards sustainable transportation. However, the adoption rate of electric motorcycles in West Kalimantan remains low. This study aims to analyze the factors shaping the intention to adopt electric motorcycles in this region using an extended Technology Acceptance Model (TAM) framework. A quantitative method was employed, involving a survey of 200 respondents selected through purposive sampling, with the data analyzed using Structural Equation Modeling (SEM). The results indicate that perceived usefulness and perceived ease of use have a positive and significant influence on adoption intention. Notably, perceived ease of use emerged as the most dominant determinant, not only directly impacting intention but also indirectly influencing it through perceived usefulness. Among the external variables, compatibility was found to enhance perceived usefulness, while enjoyment positively affected perceived ease of use. Conversely, resource availability did not significantly shape initial perceptions. The implications of these findings suggest that stakeholders should prioritize strategic communication that highlights the ease of use, enjoyable riding experience, and functional benefits of electric motorcycles. These efforts should be supported by policies aimed at accelerating infrastructure development and providing incentives to encourage broader adoption.
