### Kesulitan Siswa dalam Menyelesaikan Masalah Geometri

Geometri merupakan materi yang sangat penting untuk dipelajari oleh siswa karena banyak konsep matematika yang dapat ditunjukkan atau dijelaskan dengan representasi geometris. Selain dapat menumbuhkembangkan kemampuan berpikir logis, geometri juga efektif untuk membantu menyelesaikan permasalahan dalam banyak cabang matematika. Di antara cabang matematika yang lain, geometri mendapat porsi paling besar dalam kurikulum dari SD sampai SMA. Tulisan ini bermaksud mengidentifikasi kesulitan siswa dalam menyelesaikan masalah geometri dengan mengkaji hasil-hasil penelitian yang sudah ada. Hasil kajian ini adalah adanya dua jenis kesulitan yaitu kesulitan memahami konsep geometri dan kesulitan menyelesaikan masalah geometri. Kesulitan memahami konsep geometri meliputi kesulitan dalam memahami definisi bangun geometri seperti sudut, garis, simetri, bidang, dan ruang serta kesulitan mensintesis hubungan antar bangun geometri seperti membandingkan segitiga samakaki dengan samasisi dan membandingkan persegi dengan persegipanjang. Adapun kesulitan menyelesaikan masalah geometri terjadi saat membaca dan memahami masalah, kesulitan mentrasformasikan soal ke dalam model matematika, kesulitan keterampilan proses penyelesaian masalah, dan kesulitan dalam menarik kesimpulan. Kesulitan tersebut terjadi karena geometri merupakan materi yang abstrak dan kompleks. Untuk mengatasi kesulitan tersebut diperlukan solusi terutama dalam proses pembelajaran agar materi geometri yang sulit bisa disajikan dengan baik sehingga membantu siswa untuk memahami materi tersebut

### Synthesis of Halogen Substituted Chalcone Againts Cervical Cancer (HeLa) Cell Lines using Green Method

Cervical cancer is the second leading cause of death in women. Many cancer treatments currently provide toxic effects on normal cells. Therefore, alternative treatment using chalcone derivatives has potent anticancer properties that can help reduce cancer side effects. Chalcone derivatives with halogen and methoxy groups in ring B can potentially inhibit cancer cells. This research aimed to synthesize halogen-substituted chalcone by a green chemistry approach and determine activity against cervical cancer (HeLa) cell lines. The Claisen-Schmidt reaction was used to synthesize 2'-hydroxy-2-bromo-4,5-dimethoxychalcone using a grinding technique. The purity of the synthesized compound was determined using thin-layer chromatography and melting range. The compounds' structures were characterized using FTIR, MS 1H, and 13C-NMR. The result showed that the synthesized compound was yielded in 53% as a yellow solid. In vitro cytotoxicity of the synthesized chalcone was evaluated by the MTT assay method. The IC50 of the compound was 67,23 μg/mL as a moderate activity inhibiting cervical cancer (HeLa) cell lines. Based on the IC50 value, this compound can be a candidate for anticancer against Cervical cancer (HeLa) cell line

### The Relationship Between Perceived Transformational Leadership Style and Organizational Commitment in Kindergarten Teachers

This study aims to determine the positive relationship between perceptions of the principal's transformational leadership style and organizational commitment in teachers/educators. Organizational commitment should be owned by every teacher/educator to achieve the goals of the educational institution listed in the vision and mission of the educational institution. However, commitment to the organization could be more concern for educational institutions. This study is to fill the literature gap and provide direction to stakeholders as a consideration for making references regarding transformational leadership style and teacher organizational commitment. The data collection method in this study used a scale with the Likert Model scale scoring technique. The hypothesis in the study is that there is a relationship between the perception of the principal's transformational leadership style and the teachers' organizational commitment. The population and sample in the study were all educators in kindergartens in Cilacap District, totaling 30 teachers/educators. Data collection methods using the Transformational Leadership Style scale and Organizational Commitment scale. The results of the Pearson Product Moment correlation analysis of the two variables amounted to (rxy) 0.402 (p &lt; 0.014). The results showed a positive and very significant relationship between the perception of transformational leadership style and organizational commitment in teachers in kindergarten. The coefficient of determination of the correlation coefficient is R2 = 0.162. The conclusion from the data presented shows that leadership style provides an effective contribution to organizational commitment in teachers by 16.2%. The usefulness of this research is the need and importance of leadership style to determine the organizational commitment attached to teachers

### Educator's Strategy in Stimulating Speech Delay for Children with Mild Mental Retardation

When communicating with the surrounding environment, speech delay or speech disorder generally occurs in normal children or children with special needs with language development disorders. Children with special needs with mental retardation tend to have various disorders, including speech delay, which requires treatment as soon as possible with the right strategy and stimulation. This study aims to describe educator strategies in stimulating mild retarded disabled children who experience speech delay. This study uses a descriptive approach through case studies of a child with mild mental retardation category having speech delay disorder. Data collection techniques used observation and interviews conducted directly at SLB-C Dharma Rena Ring Putra I Yogyakarta. At the same time, the data analysis technique uses the Miles and Huberman models with the data analysis stages, namely data reduction, data presentation, concluding, and verification by testing data wettability using triangulation techniques. The study results show that the language development of children with speech delay disorders in children with mild mental retardation can develop optimally through strategies that educators provide with various stimulations. The findings in this study are aspects that significantly influence dealing with speech delay disorder, namely parenting parents, speech therapy activities, educators understanding children's language in communicating, and exciting learning media through videos or pictures
