Permasalahan dari budidaya udang vaname yaitu pada pemantauan kualitas air yang hanya dapat di cek satu persatu menggunakan satu alat saja. Dampak yang dapat terjadi pada kolam udang vaname yaitu munculnya penyakit pada udang yang disebabkan oleh parameter air yang kurang baik. Sehingga muncul ide untuk membuat suatu sistem pemantauan kualitas air yang lebih efisien guna menanggulangi matinya udang pada kolam udang vaname yang hasil pembacaan nya dapat dibaca dengan media wireless melalui aplikasi. Pada penelitian ini di buat alat pemantauan kualitas air pada kolam udang vaname menggunakan NODEMCU ESP8266 berbasis IoT yang terdiri dari sensor pH 4502-C dan sensor suhu DS18B20. Input pada sensor-sensor tersebut akan di olah pada NODEMCU ESP8266 yang kemudian di koneksikan dengan aplikasi Blynk guna menampilkan data dari sensor-sensor. Berdasarkan hasil pengujian menunjukan bahwa pada sensor pH dan sensor suhu selama 10 hari saat siang dan sore. Dengan nilai rata-rata pada siang hari pH 7,84, suhu 30.1?C. Nilai rata-rata pada malam hari pH 7,49, suhu 29,2?C

The use of learning media is crucial to support material delivery, enhance understanding, and encourage active student participation. In the digital age, leveraging technology, such as computers and interactive multimedia, is essential for creating engaging and effective learning experiences. This research aims to assess the validity level of animated video-based learning media using the Doratoon application for IPAS (Science, Social Studies, and Arts) subject on energy transformation in 4th-grade elementary school. The validation process involved language experts, material experts, and media experts, utilizing Likert scale validation sheets as instruments, focusing on content feasibility, design appearance, and technical ease of use. This study was conducted at UPT SD Negeri Jadi III, Tuban, involving 1 teacher and 25 4th-grade students. Data were collected through observation, interviews, questionnaires, test sheets, and validation sheets, then analyzed using descriptive quantitative methods. The validation results showed percentages of 88% from language experts, 88% from material experts, and 86% from media experts. The overall average validity reached 87.33%. Based on validity criteria, this learning media is categorized as "Very Valid" and is suitable for use in the learning process. It is hoped that this media can be a valid interactive alternative capable of optimizing students' critical thinking skills.

Penelitian ini bertujuan untuk merancang jam tangan inovatif dengan memanfaatkan limbah batok kelapa sebagai upaya optimalisasi bahan lokal yang berkelanjutan. Indonesia, sebagai salah satu negara penghasil kelapa terbesar di dunia, menghasilkan jutaan ton limbah batok kelapa setiap tahunnya yang belum dimanfaatkan secara maksimal. Limbah ini umumnya hanya dibakar atau dibuang, sehingga menimbulkan permasalahan lingkungan yang cukup serius. Melalui pendekatan desain produk berkelanjutan dan eksplorasi material alternatif, batok kelapa dipilih karena memiliki potensi yang tinggi dalam aspek kekuatan material, nilai estetika, dan keberlanjutan. Dalam penelitian ini, batok kelapa diolah menjadi casing jam tangan yang memiliki nilai estetis, ergonomis, serta potensi komersial sebagai produk kriya kontemporer. Metode penelitian yang digunakan adalah deskriptif kualitatif, dengan teknik pengumpulan data berupa wawancara mendalam kepada pelaku industri kreatif, observasi langsung terhadap proses pembuatan kerajinan batok kelapa, serta studi literatur yang relevan. Proses perancangan meliputi beberapa tahapan, yaitu analisis kebutuhan pengguna, pembuatan sketsa desain, pengembangan bentuk, visualisasi 3D, dan pembuatan prototipe dengan teknik handmade. Hasil perancangan menunjukkan bahwa batok kelapa memiliki karakteristik unik seperti kekuatan struktural, bobot ringan, serta tekstur alami yang mendukung penciptaan produk jam tangan dengan daya tarik visual tinggi. Produk yang dihasilkan tidak hanya berfungsi sebagai penunjuk waktu, tetapi juga sebagai simbol gaya hidup ramah lingkungan dan representasi identitas lokal. Inovasi ini diharapkan dapat berkontribusi terhadap pengurangan limbah, pengembangan ekonomi kreatif, serta edukasi masyarakat mengenai pentingnya pemanfaatan limbah organik dalam praktik desain produk yang berkelanjutan.

The purpose of this study is to produce and develop a valid, practical, and effective learning media product based on Wordwall for fifth-grade students. This study is a research and development (R&D) study using the ADDIE model (Analyze, Design, Development, Implementation, and Evaluation). The subjects of the study consisted of 17 fifth-grade students, the fifth-grade teacher at UPT SDN Sukoharjo, and three validators. Data was collected through several instruments, including observation sheets, student and teacher interview sheets, expert validation sheets, student and teacher response questionnaires, and student test sheets. Data analysis was conducted using qualitative and quantitative data analysis techniques, where the collected data was examined for validity, practicality, and effectiveness. This study concluded that the Wordwall-based learning media is suitable for use based on the percentage scores obtained from media experts (80%), subject matter experts (80%), and language experts (82.2%), each of which met the validity criteria. The effectiveness data from the student test was 70%, categorized as sufficiently effective. Additionally, the practicality data from the student response questionnaire was 96% and the teacher response was 96%, meeting the criteria for highly practical. Based on the data obtained, it can be concluded that the Wordwall-based learning media meets the criteria for validity, practicality, and effectiveness as a learning medium

This study aims to test the validity of interactive e-Booklet learning media developed to improve student learning outcomes. An e-Booklet is an innovative medium designed to present information through visual displays, audio, and direct interaction, thereby enhancing students' engagement and understanding of abstract material. Validation was conducted by three experts: a subject matter expert, a media expert, and a language expert, using a Likert scale-based assessment instrument. This research is a developmental study with a descriptive quantitative approach. Data collection techniques included observation sheets, questionnaires, and validation sheets. The validation results by the language expert showed a score of 89% (valid category), the subject matter expert obtained a score of 80% (sufficiently valid category), and the media expert obtained a score of 84% (valid category). The overall average validation score for the e-Booklet media was 85%, indicating that this media falls into the ‘valid’ category and is suitable for use in the learning process. Thus, the e-Booklet media meets the criteria for content, presentation, and technical aspects, and has great potential to support student learning outcomes.
