Internet of Things (IoT) needs to be developed in education and serves as one of the roles of education to face the industrial revolution 4.0. Vocational High School (SMK) is an appropriate level of education to prepare early for knowledge and application of IoT technology. Vocational High School Jakarta 1 has good technology but the competency of applying IoT expertise is still lacking. To improve the understanding and application of IoT, Physics Engineering Study Program of Binawan University proposes a solution in the form of training with the theme: Implementing Internet of Things (IoT) to improve student competence in Vocational High School Jakarta 1. This training aims to introduce about IoT especially implementation in the scheme monitoring by using light and temperature sensors to increase student motivation and competence in the industrial era 4.0. Based on the analysis of the data, it was concluded that the competency of student expertise could be significantly increased through IoT training to be accepted with significance level of 0.05. The method of implementing training is team work that is able to make the training more effectively and efficiently.

Teknik sampling penelitian adalah Probability sampling dengan teknik Total Quota Sampling dengan jumlah sampel sebanyak 20 mahasiswa. Instrumen pengumpulan data yaitu berupa tes berbentuk pretest dan posttest. Instrumen disusun dalam bentuk soal pilihan ganda sebanyak sepuluh soal dengan tingkat kesulitan yang berbeda. Data penelitian dianalisis secara deskriptif dimulai dari uji normalitas, homogenitas dan uji hipotesis. Hasil penelitian menunjukkan bahwa terdapat peningkatan prestasi belajar mahasiswa dengan menggunakan e-modul interaktif berbasis Schoology.
The Centrifugal liquid Membrane (CLM) method, which provides an ultra-thin two-phase liquid membrane system in a rotating glass cell, was successfully applied to Green Synthesis from Polyscias scutellaria (PS) capped gold nanoparticles (AuNPs-PS) using a Mangkokan leaf (Polyscias scutellaria) extract as a reducing agent and stabilizer in the hexane-water system. PS extract in hexane fraction as the organic phase has a UV absorption spectrum at the maximum wavelength, λmax of 220 nm, while the precursor of HAuCl4 solution as an aqueous phase has an λmax of 214 nm. Investigation of AuNPs-PS formation was carried out at various concentrations of Mangkokan leaf extract concentration; i.e., 0.001 0.003; 0.005; 0.007 and 0.009%, while the reaction was carried out at various rotational speeds of 5,000-9,000 rpm. The formation and stability of AuNPs-PS were observed from the phenomenon of surface plasmon resonance (SPR) and absorbance changes as measured by a UV-Vis spectrophotometer. The results of measurements using CLM-Spectrophotometry shows the formation of AuNPs-PS in the hexane-water system at λmax of 534 nm.
Usia merupakan faktor yang secara langsung berhubungan dengan Indeks Massa Tubuh (IMT). IMT diatas normal disebut obesitas sehingga dapat meningkatkan kadar glukosa darah. Tujuan penelitian ini adalah untuk mengetahui hubungan indeks massa tubuh dengan kadar glukosa darah puasa pada usia dewasa dan lansia di Puskesmas Kecamatan Kramat Jati. Metode penelitian yang digunakan adalah observasional deskriptif analitik, desain penelitian dilakukan secara cross sectional prospektif dengan sumber data primer. Data yang telah terkumpul dianalisis secara statistik menggunakan SPSS dengan dianalisis secara univariat dan bivariat dengan menggunakan uji pearson correlation. Hasil penelitan menunjukan bahwa dari 32 responden tidak terdapat hubungan yang signifikan antara IMT dengan kadar glukosa darah puasa pada usia dewasa dan lansia dengan p value > 0,05.
Potato peel flour (Solanum tuberosum) is a flour that has a potential to be developed as a food source of potassium. This research was conducted to determine the chemical properties of potato peel flour. Potato peel flour is carried out in several stages: peeling potatoes; soaking in 0.3% sodium bisulfite (NaHSO3) solution for 60, 90 and 120 minutes; drying; milling; and sifting. Parameters observed were water content, ash content, protein, fat, carbohydrates and potassium (K). Potato peel flour with various immersions produced has the characteristics of water content (7.84 – 9.03%), ash content (4.15 – 4.67%), protein (11.35 – 11.60 %), fat ( 0.74 – 0.87%), carbohydrates (74.63 – 75.26%), and potassium (1231.32 – 1671.86 mg/100 g). Based on the potassium content, potato skin flour with the highest potassium content was soaked for 120 minutes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
