Abstract

Penelitian ini bertujuan untuk mengetahui komposisi kimia, hasil skrining fitokimia, dan aktivitas antioksidan ekstrak buah bakau api-api putih (Avicennia marina). Analisis komposisi kimia meliputi kadar air, abu, protein, lemak, dan karbohidrat. Penelitian menggunakan rancangan acak lengkap (RAL) dengan dua perlakuan metode ekstraksi dan dua kali ulangan, yaitu metode maserasi menggunakan etanol 70% dan metode perebusan. Data dianalisis menggunakan analisis varians (ANOVA) pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa perbedaan metode ekstraksi memberikan perbedaan rendemen yang signifikan. Rendemen ekstraksi dengan metode perebusan lebih tinggi dibandingkan metode maserasi, masing-masing sebesar 45,07 ± 0,50% dan 7,50 ± 0,21%. Komposisi kimia buah api-api putih menunjukkan bahwa kadar karbohidrat merupakan komponen tertinggi dibandingkan kadar air, abu, protein, dan lemak. Hasil skrining fitokimia menunjukkan bahwa kedua metode ekstraksi tidak berbeda nyata dan sama-sama mengandung senyawa alkaloid, steroid, triterpenoid, flavonoid, saponin, dan tanin. Aktivitas antioksidan diuji menggunakan metode DPPH untuk menentukan nilai IC₅₀. Ekstrak hasil maserasi menunjukkan nilai IC₅₀ sebesar 59,58 ± 8,62 ppm, sedangkan metode perebusan sebesar 80,09 ± 6,70 ppm. Nilai IC₅₀ tersebut termasuk dalam kategori aktivitas antioksidan kuat.

Abstract

Introduction: The incidence of Type 2 Diabetes Mellitus (T2DM) in Indonesia remains high and can lead to both macrovascular and microvascular complications, making research on the use of T2DM medications and their complications an important area of study. This study examines the use of oral antidiabetic drugs in T2DM patients with macrovascular and microvascular complications at Dr. Soetomo General Academic Hospital, Surabaya, Indonesia. Methods: A descriptive, retrospective study was conducted using total sampling of medical records with the inclusion criteria of this study being 162 patients who were treated in the Internal Medicine Outpatient at Dr. Soetomo General Academic Hospital, Surabaya, Indonesia, for the period of July–September 2023 with the diagnosis code ICD-10 E11 and were treated with oral antidiabetic drugs. The exclusion criteria of this study were patients who are using insulin as their primary therapy. Results: Out of 162 patients, the demographic distribution showed that most patients were female (51.23%), with the highest age group being 55-64 years (41.35%). Body Mass Index (BMI) was mostly in the 18.5-22.9 and 23-24.9 ranges (33.95%), and the majority had been living with DM for 6-10 years (44.44%). Monotherapy, primarily metformin, was commonly used across all microvascular (retinopathy, nephropathy, neuropathy) and macrovascular (stroke, coronary heart disease (CHD), peripheral artery disease (PAD)) complications. The most frequently used combination therapy was metformin + glimepiride. Conclusion: The use of metformin as monotherapy and the combination of metformin and glimepiride were the most commonly used treatments for T2DM patients with complications.

Abstract

This research examines the legal framework and implementation of Foreign Direct Investment (FDI) in Indonesia within the context of national development. The primary issue addressed is the distinction between direct and indirect investment and the legal requirements for foreign entities operating within the Republic of Indonesia. Using a normative judicial approach with descriptive analysis, the study gathers data from primary legal sources, including the 1945 Constitution, Law No. 25 of 2007, and Law No. 40 of 2007. The findings indicate that FDI must generally take the form of a Limited Liability Company (PT) under Indonesian law. Successful investment realization depends on legal certainty, bureaucratic efficiency, and a conducive business climate. The research concludes that while direct investment requires a physical presence and risk-bearing by the investor, indirect investment focuses on short-term capital gains through the capital market. The implication is that Indonesia must maintain stability, predictability, and fairness in its investment regulations to remain competitive in the global economy and the ASEAN Economic Community.

Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk menganalisis pemahaman, pengalaman, tantangan, dan kesiapan guru dalam mengembangkan perangkat pembelajaran sains yang berdaya saing global melalui lokakarya Hybrid Deep Learning dan STEM Project-Based Learning (STEM-PjBL). Menggunakan pendekatan deskriptif kualitatif dengan desain penelitian tindakan partisipatif, penelitian ini melibatkan 29 guru sains dari MGMP di Muaro Jambi, Indonesia. Data dikumpulkan melalui kuesioner dan observasi sebelum, selama, dan setelah lokakarya, dan dianalisis menggunakan model interaktif Miles dan Huberman. Temuan penelitian mengungkapkan bahwa guru umumnya memiliki pengetahuan terbatas tentang pembelajaran mendalam dan hybrid deep learning, pengalaman minimal dalam menerapkan STEM-PjBL, dan menghadapi tantangan signifikan seperti fasilitas terbatas, kompetensi pedagogis yang tidak memadai, dan kurangnya dukungan kelembagaan. Terlepas dari keterbatasan ini, sebagian besar guru menunjukkan kesiapan dan motivasi yang tinggi untuk mengintegrasikan teknologi berbasis AI dan pendekatan berbasis proyek ke dalam praktik mengajar mereka, dengan syarat mereka diberikan bimbingan intensif dan pengembangan profesional berkelanjutan. Kebaruan program ini terletak pada integrasi Pembelajaran Mendalam Hibrida dengan STEM-PjBL sebagai model untuk meningkatkan kapasitas guru dalam merancang perangkat pembelajaran sains inovatif berbasis teknologi. Implikasinya menyoroti pentingnya pelatihan profesional berkelanjutan, dukungan institusional, dan kemitraan kolaboratif untuk memastikan keberhasilan implementasi pedagogi berbasis AI dan berbasis proyek dalam pendidikan sains.

Abstract

Tax avoidance is a tax avoidance effort that is carried out legally for individual and corporate taxpayers without conflicting with existing tax regulations by exploiting the weaknesses (grey area) contained in the Law and Taxation Regulations in order to produce a lower tax amount. This study aims to examine the effect of profitability, tax incentives, and corporate social responsibility on tax avoidance. Profitability is a ratio that indicates a company’s ability to generate profits. Tax incentives are facilities in the form of reduced tax rates provided by the government. Corporate Social Responsibility (CSR) is a company’s commitment to participating in sustainable economic development to improve the quality of life and the environment in a beneficial way. The population in this study consists of companies in the basic materials sub sector listed on the Indonesia Stock Exchange (IDX) from 2020 to 2024. The sampling technique used is purposive sampling, resulting in a total sample of 14 companies. The data analysis method uses Structural Equation Modeling (SEM) with Smart PLS Version 4.0.

Abstract

This study aims to analyze institutional ownership, profitability, liquidity, and solvency on company value in insurance companies listed on the Indonesia Stock Exchange for the period 2019-2024. The research method uses a quantitative approach with a causal design and uses secondary data from financial reports officially published by the IDX (www.idx.co.id) with data processing assisted by SPSS version 25. Company value is measured using price book value (PBV), institutional ownership is described by the percentage of institutional share ownership, profitability is measured by return on assets (ROA), liquidity by the current ratio (CR), and solvency by the debt to equity ratio (DER). The results of the study indicate that institutional ownership and profitability do not have a significant effect on company value. However, liquidity and solvency have a significant effect on company value. In conclusion ,indicates that investors in the insurance sector consider the company's ability to maintain financial stability and capital structure more than ownership structure and profits in determining company value
