Abstract

Geothermal brine merupakan limbah cair dari pembangkit listrik tenaga panas bumi yang mengandung silika dalam jumlah tinggi. Kandungan silika ini berpotensi dimanfaatkan sebagai bahan baku silika gel bernilai ekonomi. Penelitian ini bertujuan untuk mengekstraksi silika gel dari geothermal brine PLTP Lumut Balai menggunakan metode presipitasi kimia (sol-gel) dengan waktu reaksi tetap 30 menit. Proses diawali dengan penambahan larutan NaOH pada konsentrasi 1,25%, 1,50%, 1,75%, dan 2,00% untuk melarutkan silika menjadi natrium silikat, diikuti dengan penambahan HCl hingga terbentuk gel. Produk dikeringkan dan dikarakterisasi meliputi kadar air, kapasitas adsorpsi air, pH, dan komposisi kimia. Hasil terbaik diperoleh pada konsentrasi 2,00% dengan kadar air 1,33%, kapasitas adsorpsi air 25,4%, pH netral (6), dan kandungan SiO₂ sebesar 89,57%. Metode sol-gel terbukti efektif dalam mengekstraksi silika gel dari limbah geothermal brine.

Abstract

The development of the industrial revolution has brought human’s civilization in applying ICT (Information and Communication Technology) massively. The Indonesian government is trying to achieve “Indonesia Connected”. Unfortunately many Indonesian citizens don't have any access and enough knowledge about ICT itself. The research project presents a solution for the problem above. We hope the research project will be able to give a great description about how ICT-Volunteer helps people socializing digital literacy and helps people to access TIK in Indonesia. The research project uses the approach “perfective system”. The definition of perspective system is a study on a system by questioning: how and why the system can work properly. The researcher will enter the system doing an observation figuring out how ICT-volunteers of Indonesia work doing their volunteering job. Many activities have been done by Bapak Bambang Soeprijanto as the director of informatics empowerment since 2008. He has made some meetings, collaboration and coordination among stakeholders in building Indonesian informatics society. (relawantik.or.id, n.d.). The director of informatics empowerment, Ibu Mariam F. Barata, in 2011 continued the policy by supporting bigger meetings such as communication forum, coordination, collaboration and an event “Kerjasama Komunitas TIK“ (FK5T) national level. That event also established an organization, Relawan TIK on July 4th, 2011. It was witnessed by the General Director of Informatics Application. Kemkominfo, Ashwin Sasongko. It was decided as the anniversary of Relawan TIK Indonesia. (Indonesian ICT-volunteer). Being a member of Relawan TIK has many benefits such as an opportunity of sharing knowledge and skill of ICT, improving communication and leadership skill, building networking and positive social relationship.

Abstract

Integrating local culture into science education is a strategic effort to enhance the relevance of learning to students' lives while fostering appreciation for regional heritage. In the context of biology education, incorporating culturally-rooted examples can make abstract concepts more tangible and relatable. This study investigates teachers’ and students’ perceptions of a digital biology e-module integrating golok tarisi local heritage within an Ethno-STEAM approach supported by Augmented Reality (AR). The module connects biodiversity, ecology, and sustainable resource use concepts with cultural practices. This research employed a mixed-method (qualitative–quantitative descriptive) design involving 16 biology teachers and 60 eleventh-grade students selected purposively. Data were collected through Likert-scale questionnaires, semi-structured interviews, and classroom observations, and analyzed using descriptive statistics and thematic analysis. Results show highly positive perceptions. A total of 87% of teachers considered the e-module highly relevant, and 82% found it easy to use. Among students, 85% reported increased engagement and 78% higher learning motivation. The e-module also supported digital literacy development through the use of multimedia and AR features, although 18% of teachers experienced technical challenges. Students reported improved conceptual understanding of biodiversity and ecological balance, supported by AR visualization of the golok tarisi production process. Observations confirmed increased interaction and critical thinking. The findings demonstrate that the Ethno-STEAM-based digital e-module is pedagogically effective and well-accepted by both teachers and students. It enhances engagement, learning motivation, digital literacy, and conceptual understanding of abstract biological concepts through AR-supported visualization. Despite minor technical constraints, the module fosters interactive, critical, and culturally meaningful biology learning. This study contributes to the development of contextual, interactive, and sustainable models for biology education.

Abstract

Perkembangan teknologi dan pembangunan yang pesat, memberikan dampak negatif yaitu mengakibatkan kualitas udara semakin menurun akibat terkontaminasi oleh polutan yang berasal dari aktivitas pembakaran sampah, gas buang kendaraan bermotor, dan kegiatan industri yang menghasilkan polusi. Pekerja atau karyawan kantoran seringkali lalai dalam memperhatikan kualitas udara dalam ruang kerjanya hal yang bisa menurunkan kualitas udara dalam ruangan adalah hasil dari AC dan atau gas sisa pembakaan lainya sehingga menyebabkan kerugian bagi manusia. Selain itu, gas-gas tersebut juga mengakibatkan terjadinya efek rumah kaca. Untuk mengatasi masalah tersebut, dirancanglah sebuah sistem monitoring gas berbahaya karbon monoksida menggunakan protokol TCP/IP untuk mengirimkan data ke platform IoT Ganesha16. Dalam input sistem digunakan sensor MQ-135 yang dapat mendeteksi metana. Data dari sensor akan dikirimkan ke Arduino, kemudian ditampilkan pada Led Matrix P10 sebagai Tampilan dan diteruskan melalui modul wifi ESP8266 agar dapat dikirimkan ke platform IoT Ganesha16. Data yang dikirimkan ke web server menggunakan protokol TCP/IP untuk kemudian ditampilkan dalam web server Ganesha16 agar data dapat ditampilkan secara realtime. Dalam eksekusi keseluruhan program yang dijalankan, didapatkan bahwa antara proses pertama (pembacaan sensor) sampai ke menampilkan data di Ganesha16 di dapatkan delay rata-rata 1,95 second. Delay pada bagian TCP/IP didapatkan rata-rata 1,37 second pada waktu realtime.

Abstract

The purpose of this study is to analyse the early childhood education management strategies aimed at improving the quality of student learning. The basic problem stems from the challenges in managing early childhood education, particularly in terms of limited human resources, curriculum adaptation, and the need for strengthening learning quality that focuses on children's character and interests. This study employs a qualitative descriptive approach, utilizing data collection techniques such as observation, documentation, and interviews with the principal, educators, and educational staff. The data analysis is conducted through triangulation, reduction, presentation, and conclusion drawing, along with data validation tests. The findings reveal that the educational management strategy is carried out through planning, organizing, implementation, and supervision functions. The learning planning is detailed based on the Merdeka curriculum, taking into account the students' needs and characteristics. Organizing is done flexibly by distributing educator tasks in accordance with the needs and adapting to the limitations of human resources. The learning implementation focuses on character development, interest and talent enhancement, and child-centre play principles as the main focus of educational activities. Supervision is carried out by the principal with communicative supervision to conduct internal and cooperative monitoring. This management strategy has a positive impact on the improvement of learning quality, educator professionalism, and active student involvement. The study recommends strengthening human resource management through continuous training and further research on developing an adaptive and inclusive early childhood education management model.
