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.

Abstract

Guru memahami bahwa matematika sering dipandang sebagai mata pelajaran kurang diinginkan, ditakuti dan dihindari oleh sebagian besar siswa. Berbeda pilihan yang digunakan guru dalam kedua pendekatan untuk mengajar matematika matematika atau juga metode yang digunakan siswa untuk menguasainya konsep matematika dan dapat menyelesaikan tugas-tugas pemecahan masalah. Tujuan Tujuan artikel ini adalah untuk mendeskripsikan pentingnya penguasaan konsep matematika dalam menyelesaikan tugas matematika sekolah dasar. Kejuaraan Konsep matematika inilah yang menjadi dasar pemecahan masalah matematika berpikir tingkat lanjut. Dalam pendidikan dasar siswa menyebabkan memiliki keterampilan kognitif yaitu kemampuan analitis (C4), mengevaluasi (C5) dan bahkan membuat (C6). Keterampilan ini berkaitan erat dengan banyak pertanyaan yang mengarah pada pemecahan masalah matematika Dengan demikian guru melatih siswa memecahkan soal masalah matematika dimana siswa harus memiliki keterampilan manajemen konsep matematika.

Abstract

There are still many children and even teenagers who do not have any knowledge about First Aid for Fainted People, there are still many who have problems practicing what should be done first in helping someone who is Fainting, therefore the author conducted research on First Aid for Fainted People. 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.

Abstract

Background: Papillary thyroid carcinoma (PTC) is an indolent thyroid malignancy with clinicopathological features that play a role in prognosis. BRAFV600E mutations in PTC are associated with poor prognosis, and BRAFV600E immunohistochemical staining exhibits high specificity and sensitivity. This study aims to determine the association between BRAFV600E immunohistochemical expression and clinical features and histopathological subtypes in PTC.Method: This analytical observational study utilizes a cross-sectional approach, conducted from March to December 2024 at the Anatomical Pathology Laboratory, Faculty of Medicine, Universitas Sumatera Utara, and affiliated hospitals. A total of 35 PTC samples were selected and continued with BRAFV600E immunohistochemical staining. Clinicopathological data, including age, gender, tumor size, lymph nodes, metastasis, lymphovascular invasion, disease stage, and PTC subtype, were collected. Statistical analysis was performed using Somers'd (ordinal-ordinal) and Eta (nominal-ordinal) correlation test in SPSS.Results: PTC was most prevalent among females and the age group under 45 years. Predominant clinical features included tumor sizes exceeding 4 cm (T3), an absence of lymph node involvement (N0), and no detectable metastasis (M0). The classic subtype emerged as the most frequent histopathological variant, typically presenting without lymphovascular invasion (LVI) and diagnosed at Stage I. While most parameters showed no significant statistical association with BRAFV600E expression (p 0.05), a significant relationship was identified specifically regarding the cancer stage (p 0.05).Conclusion: There are no significant associations observed between BRAFV600E immunohistochemical expression and the majority of clinicopathological factors. However, a significant relationship with disease stage was identified. These findings suggest that BRAFV600E expression may have potential value as an indicator of disease stage in PTC.

Abstract

Purpose of the study: This study aims to analyze the mechanisms of corporate-community collaboration in CBT development. It specifically seeks to answer: "How does the partnership between PT. Vale and the local community shape the implementation and outcomes of CBT at Ide Sorowako Beach?" The research also identifies the key supporting and inhibiting factors within this tripartite governance model. Methodology: Employing a qualitative descriptive design, this study is grounded in a phenomenological approach to understand stakeholder experiences and a collaborative governance theoretical lens to analyze partnership structures. Data were collected via in-depth interviews, participatory observation, and document analysis involving government officials, PT. Vale management, and local community members (n= [isi jumlah informan]). Data were analyzed thematically using an interactive model, with triangulation ensuring validity and credibility. Main Findings: The analysis reveals that PT. Vale’s management adopts a participatory approach, actively involving the community in operational decision-making, which has led to direct economic benefits. However, community participation remains limited to the operational level, with strategic planning still dominated by corporate agendas. Key supporting factors are the site's natural capital and corporate resource provision. Novelty/Originality of this study: This study contributes to the CBT literature by providing an empirical analysis of a hybrid governance model where corporate CSR initiatives directly interface with community-driven tourism. It moves beyond generic CSR descriptions to dissect the mechanics and power dynamics of such partnerships. T
