Abstract

This research aims to study the concentration effect percentage weight of kayu jawa latex on the conductivity of membranes made from chitosan-PVA-lithium. The ionic conductivity of the membrane chitosan-PVA-lithium-latex kayu jawa was measured by impedance spectroscopy. The measurement results showed that membrane with the addition of 15% latex kayu jawa provided the highest conductivity values of 10.99353 x 10-4 S/cm. Characterization of the polymer electrolyte batteries that made from chitosan-PVA-lithium with the addition of latex kayu jawa have voltage of 1.5 Volts compared to commercial batteries that have tension was 1.5 Volts. These results indicated that latex kayu can be used as a filler to increase the ionic conductivity.

The aim is to provide more knowledge about First Aid for Fainted People. The methods used in this research are interviews, observation and documentation. The results of this research are that the cause of fainting is a lack of blood supply, so that the intake of oxygen and blood sugar to the brain is reduced. So the first aid that must be done is to give the patient a chance to breathe, position one hand perpendicular to the chest and the other hand bent towards the face, lift one leg that is further away from your position until it forms a 90 degree angle, try to wake it up. By shaking his body, calling his name in a loud voice, slowly patting him or using ADTD (lift your chin and press your forehead.

Abstract

This research aims to find out to what extent playing crank can improve the gross motor skills (body balance) of Grade 1 children at SD IT Al Hidayatul Jannah. The type of research used is classroom action research using descriptive analysis methods. Data obtained from observations were analyzed using qualitative descriptions by processing data from observations in the engklek game activity. The subjects in this research were 20 grade 1 students. The results of this research showed that the results of the engklek game activity were almost 100% complete in the game, out of 20 students there were only 3 students who did not complete this balance training game, because they did not understand how to play and did not pay attention to the information provided by the examiner. This shows an increase in learning outcomes for gross motor skills (body balance) carried out in the traditional engklek game.

Abstract

Penelitian ini mengkaji pengaruh Komisaris Independen (KI) dan Intensitas Rapat Komite Audit (IRKA) terhadap Kecurangan Laporan Keuangan (FSF) pada perusahaan sektor batu bara di Indonesia, dengan Struktur Kepemilikan asing (FOS) sebagai variabel moderasi. Latar belakang penelitian ini adalah munculnya kasus manipulasi laporan keuangan pada emiten besar seperti PT Bumi Resources dan PT Adaro Energy, yang menunjukkan kelemahan fundamental dalam penerapan Tata Kelola Perusahaan (GCG). Menggunakan data panel dari laporan tahunan 2019–2024 yang terdiri dari 223 observasi perusahaan batu bara di Bursa Efek Indonesia (BEI), penelitian ini mengimplementasikan metode Regresi Panel dan Analisis Modek Regresi (MRA) berbasis Random Effect Model. Hasil analisis menemukan bahwa KI dan IRKA secara parsial justru berpengaruh positif terhadap FSF, menunjukkan bahwa keberadaan pengawasan formal belum cukup mencegah fraud bila tidak disertai integritas dan efektivitas substantif. Sementara itu, FOS sebagai variabel moderasi memperkuat pengaruh negatif GCG terhadap FSF, meskipun interaksi FOS dengan KI dan IRKA secara simultan terbukti efektif menurunkan risiko fraud. Temuan ini memperkuat kerangka Teori Keagenan, Teori Segitiga Kecurangan, dan Teori Pemangku Kepentingan, serta mendorong pentingnya penguatan struktur pengawasan yang adaptif terhadap tekanan eksternal dan kompleksitas industri ekstraktif. Penelitian ini berkontribusi signifikan dengan mengintegrasikan model F-Score dan moderasi FOS dalam kajian FSF.
