Abstract

Chisocheton is a large source of limonoids with various pharmacological effects, such as antiviral, antibacterial, antimalarial, antifungal, and cytotoxic activities. This study aimed to isolate, elucidate, and evaluate the cytotoxicity of limonoids from C. pentandrus stembarks. Isolation was carried out using various separation methods including extraction and column chromatography. Spectral data were analyzed by FT-IR, UV, DEPT 135°, 1H, 13C-NMR, and HRTOF-MS and compared with those previously reported to determine the chemical structure.The obtained limonoids were lasiocarpine (1), lasiocarpine B (2), pentandricine (3), and 16β-hydroxydysobinin (4); all of which were successfully isolated from C. pentandrus for the first time. The cytotoxic activity of these limonoids were also evaluated against Michigan Cancer Foundation-7 (MCF-7) breast cancer cells using PrestoBlue method. Lasiocarpine A revealed the strongest cytotoxicity with an IC50 of 42.62 µM in moderate level.

Abstract

In the tourism industry, it is important to find the fastest way to various attractions. In this research, the use of efficient and accurate algorithms facilitates the travel planning process. One algorithm that has proven effective in solving this problem is Kruskal's algorithm. The purpose of this research is to implement Kruskal's algorithm in C++ programming language to find the fastest route between tourist destinations. In this research, the C++ programming language is used to implement the Kruskal algorithm. Information about tourist attractions and distances between tourist destinations are presented in a graph. Kruskal's algorithm is used to find the shortest path using the concept of MST (minimum spanning tree). The result of this research is a C++ program that can use Kruskal's algorithm to find the fastest route between tourist destinations based on the shortest distance. The program leads to a number of tourist destinations that must be visited to get the fastest route. Using Kruskal's algorithm, the program successfully finds the fastest route between tourist destinations, considering the shortest distance. Thus, this research provides an efficient and accurate solution to the problem of determining the fastest route in the tourism industry. The resulting program can be a useful guide for tourists when planning their trips and optimizing time and effort to visit various tourist attractions.

Abstract

ABSTRACT. Limonoid group belongs to triterpenoid that has undergone further oxidation accompanied by the loss of four carbon atoms to form a furan ring in the chain. This limonoid compound is often found in the Chisocheton genus. Limonoid compounds have been known as compounds with high structural variations and this makes limonoids have diverse and interesting activities, including cytotoxic and anticancer. In the course of our continuing study for limonoid constituents that have cytotoxic activity against cancer cell lines, methanol extract of stem bark from the Chisocheton pentandrus plant provides significant activity. The methanol extract was separated using various chromatographic techniques in the normal and reverse stationary phase to produce four azadirone-type limonoid compounds (1-4). The elucidation structure of 1-4 was determined using spectroscopic methods including, UV-Visible, IR, and 1D-NMR as well as optical rotation. All four known compounds were established as trichilenone acetate (1), toonaciliaton C (2), 11α-acetoxiazadiron (3), and 16β-hydroxydisobinine (4). The cytotoxicity of compounds 1-4 was assessed by examination using the resazurin method, which showed that compound 4 was the promising constituent against the MCF-7 cells with an IC50 value of 43.1 µM and was stronger than its positive control. Keywords: Azadirone-type limonoid, Chisocheton pentandrus, cytotoxic activity, Meliaceae.

Abstract

This study aims to evaluate the implementation of differentiated instruction within the Merdeka Curriculum in mathematics learning at junior high schools in Bima Regency, Indonesia. A qualitative approach was employed, using in-depth interviews with teachers and school principals as the primary data collection technique. The findings reveal that teachers' understanding of differentiated instruction remains varied, with the majority focusing on content differentiation, while process differentiation is still limited, and product differentiation is barely implemented. The main challenges identified include limited instructional time, inadequate facilities, administrative burdens, and insufficient training. Nevertheless, even simple applications of differentiation were found to increase student participation, reduce achievement gaps, and foster learning motivation. These results highlight the positive prospects of differentiated instruction as a strategic approach to improving the quality of mathematics education, provided that teacher capacity is strengthened and supported by school policies as well as contextualized regional education policies. This study contributes to the discourse on inclusive teaching practices and offers recommendations for policy development tailored to local educational needs. Keywords: Differentiated Instruction; Merdeka Curriculum; Mathematics; Inclusive Educatio

Abstract

Era digital telah menghadirkan perubahan besar dalam dinamika pembentukan identitas remaja. Media sosial tidak hanya menjadi sarana ekspresi dan komunikasi, tetapi juga ruang yang memunculkan tekanan sosial, pencitraan ideal, dan tuntutan validasi digital. Penelitian ini bertujuan untuk mengungkap bagaimana remaja mengalami krisis identitas sebagai dampak dari penggunaan media sosial, serta bagaimana kondisi tersebut memengaruhi kesehatan mental dan relasi sosial mereka. Pendekatan kualitatif dengan desain fenomenologis digunakan untuk menggali pengalaman subjektif tiga orang remaja berusia 15–18 tahun yang aktif bermedia sosial. Data dikumpulkan melalui wawancara mendalam, observasi partisipatif, dan dokumentasi digital, kemudian dianalisis secara tematik. Hasil penelitian menunjukkan bahwa media sosial mendorong pembentukan identitas yang tidak otentik, memicu stres, kecemasan, minder, hingga ketidakstabilan emosi. Media sosial juga memperlemah kualitas relasi sosial langsung dan menimbulkan rasa kesepian. Ketahanan diri remaja dipengaruhi oleh kesadaran kritis, strategi koping, dan dukungan sosial, namun masih banyak yang tidak memperoleh pendampingan dari keluarga maupun institusi pendidikan. Penelitian ini merekomendasikan pentingnya penguatan literasi digital, pendidikan kesehatan mental, serta penciptaan lingkungan sosial yang suportif bagi remaja di era digital.
