Abstract

This study aims to develop a valid and practical web-based interactive learning media using the ADDIE model. The study was conducted at SMK Negeri 4 Solok Selatan in Wireless Network Maintenance for grade XI TKJ. The main issue identified was low student engagement and difficulty understanding the material. Validation results showed media experts rated it 88.27% as "Highly Valid," and material experts rated it 87.41% as "Highly Valid." Practicality assessments by teachers reached 95.83% as "Highly Practical," while students rated it 81.03% as "Highly Practical." Thus, this learning media is valid and practical for classroom use.

Abstract

Status gizi anak sekolah merupakan indikator penting bagi Kesehatan dan tumbuh kembang mereka, yang dipengaruhi oleh berbagai faktor, termasuk pola makan dan tingkat aktivitas fisik. Penelitian ini bertujuan untuk menganalisis hubungan antara asupan makanan dan aktivitas fisik dengan status gizi pada anak sekolah dasar di Kec. Pasie Raya Kab. Aceh Jaya. Metode yang digunakan adalah metode kuantitatif dengan desain cross-sectional. Hasil penelitian berdasarkan uji chi-square menunjukkan bahwa terdapat hubungan signifikan antara asupan makanan dengan status gizi dengan nilai p-value 0,000 > 0,05 dan tidak ditemukan hubungan signifikan antara aktivitas fisik dengan status gizi karena nilai p-value 0,433 < 0,05. Kesimpulan dari penelitian ini adalah hubungan asupan makanan dan aktivitas fisik dengan status gizi bahwa keduanya memiliki peran penting dalam menentukan status gizi anak sekolah dasar.

Abstract

Clean water plays a central role in human survival. The majority of clean water comes from groundwater. Shallow groundwater from dug wells does not necessarily have suitable quality for use because it is vulnerable to contamination. Bantan Sari is one of the villages located on Bengkalis Island. Besides having problem related to water availability, this area also has poor shallow groundwater quality. This study aims were to determine the quality of shallow groundwater in the study area and map its feasibility as a source of drinking water. This research is expected to be the basis for further research to improve groundwater quality on Bengkalis Island. The research methods included field data collection and laboratory analysis. The parameters measured consisted of color, TDS, DHL, pH, Fe and Mn levels. Based on the results of study, 14 dug wells were obtained. Groundwater color in study area were colorless (36%), yellow (7%), brown (21%), and reddish brown (36%). Groundwater TDS ranged from 59 mg/l – 560 mg/l. Groundwater DHL ranged from 107 mg/l – 1080 mg/l. Groundwater pH ranged from 6,49 – 6,74. Groundwater Fe levels ranged from 0,3 mg/l – 5,43 mg/l and groundwater Mn levels < 0,4 mg/l. Based on Minister of Health Regulation No.492/Menkes/Per/IV/2010 about drinking water quality requirements, it is known that only 1 sample (7%) is included in the drinkable category while the other 13 samples (93%) are included in non-drinkable category.
