Abstract

Environmental pollution is increasing every year. From 2011 to 2014, environmental pollution in the Special Region of Yogyakarta increased above 250 percent. The effect of environmental pollution is the decreasing availability of clean water. Universitas Sanata Dharma as an institution engaged in the field of Education seeks to provide clean water where clean water is suitable for drinking, namely with RO (Reverse Osmosis) technology. Drinking water distribution has run well in the Universitas Sanata Dharma, but it lacks hygiene. In this study, researchers Designing Independent Automatic Drinking Water Platforms that could distribute clean water ready to drink students with a certain dose. The result of this study is that an independent automatic drinking water platform can provide 200cc of clean water ready for drinking in 9 seconds each time a user (student) uses this tool.

Abstract

In daily life we have encountered many 7-segment uses. 7-segment commonly used to display public information or can also display the number of calculations (counters). Control Decoder as a 7-segment driver has also been widely marketed, which is commonly found are IC CMOS and TTL as the decoder controller. Various methods are used to counter the final goal, which is to find out the number of objects. In this research, researchers tried to do a 4-digit count-up by using the CD4510B CMOS IC as a BCD Count-Up and CD4511B as a 5-inch BCD to 7-segment decoder SM415001L and from the results of this research, the use of CD4510B ICs as BCD Up / Down Counter can generate binary numbers according to the results of the counter that is on pins Q1, Q2, Q3, and Q4. IC CMOS CD4511B which according to the datasheet is intended for 7-segment common cathode, can also be used for 7-segment common anode drivers by adding logic inverting circuits using transistors BC547 and CD4511B CMOS IC combined with a logic inverting circuit, the 7-segment 5 Inch SM415001L can display Count-Up numbers from 0000 to 9999

Abstract

Penguatan pembelajaran STEM di tingkat sekolah dasar memiliki peran strategis dalam membangun fondasi literasi sains dan teknologi sejak dini. Program pengabdian ini bertujuan mengintegrasikan teknologi sensor ke dalam pembelajaran STEM di SD Eksperimental Mangunan melalui pendekatan eksperimen langsung yang interaktif. Kegiatan mencakup pelatihan bagi guru dan siswa, serta praktikum sederhana seperti merakit dan menggunakan sensor cahaya (LDR) dan sensor suara berbasis mikrofon kondenser untuk aplikasi nyata. Siswa terlibat dalam proyek-proyek kecil, seperti membuat lampu otomatis yang menyala saat gelap menggunakan LDR atau lampu tepuk yang aktif berdasarkan suara. Metode ini mendorong siswa untuk menggabungkan prinsip STEM secara kreatif dan kontekstual, sehingga pembelajaran menjadi lebih bermakna. Evaluasi program menunjukkan peningkatan minat siswa terhadap sains dan teknologi hingga 40%, serta peningkatan kemampuan berpikir kritis dalam menyelesaikan masalah praktis. Keberhasilan program ini tidak lepas dari kolaborasi yang solid antara tim pengabdian, guru, dan pihak sekolah. Hasil ini membuktikan bahwa pembelajaran berbasis teknologi dapat meningkatkan pemahaman konsep STEM secara efektif, kontekstual, dan menyenangkan bagi siswa.

Abstract

Agriculture is a vital sector for a nation's livelihood. However, in the near future, the agricultural sector faces various challenges, particularly related to environmental and cultural issues. In this era of digital transformation, technology plays a crucial role in the agricultural field. Research is conducted to control the quality of nutrition and water intake for hydroponic plants to ensure their healthy and high-quality growth. The controlled parameters for nutrition include pH and nutrient solution availability, while water intake involves temperature, acidity (pH), electrical conductivity, and nutrient dosage. These parameters are detected by pH sensors, temperature sensors, EC (electric conductivity) sensors, and controlled by microcontrollers. The sensor detection results control the pump operation, ensuring a continuous and quality water intake rate. The growth of Brazilian spinach plants under study is observed with water pH controlled at 6.5 – 7 and nutrient electrical conductivity at 2 – 2.1 ms/cm.Test results demonstrate that the growth of plants in the research growth medium and the comparison growth medium significantly improves, even though the growth is not uniform across all plants. Plants in the research growth medium exhibit significantly better growth compared to those in the comparison growth medium.
