Abstract

Famili Poaceae merupakan kelompok tumbuhan monokotil yang memiliki persebaran luas dan berperan penting sebagai sumber pangan, pakan ternak, serta tanaman penutup tanah. Namun, informasi mengenai karakter morfologi famili Poaceae masih tersebar di berbagai sumber ilmiah sehingga diperlukan kajian yang lebih sistematis dan terintegrasi. Penelitian ini bertujuan untuk menganalisis karakter morfologi famili Poaceae berdasarkan berbagai sumber literatur ilmiah. Metode yang digunakan adalah studi literatur dengan pendekatan kualitatif melalui analisis berbagai jurnal ilmiah nasional dan internasional terbitan tahun 2022–2026. Metode studi literatur dipilih karena mampu memberikan sintesis data secara komprehensif dari berbagai hasil penelitian terdahulu. Hasil penelitian menunjukkan bahwa famili Poaceae memiliki karakteristik morfologi khas berupa akar serabut, batang beruas dan silindris, daun bertulang sejajar yang dilengkapi pelepah dan ligula, bunga berbentuk spikelet, serta buah bertipe kariopsis. Selain memiliki persamaan karakter dasar, beberapa spesies Poaceae juga menunjukkan variasi morfologi pada batang, daun, dan bunga sesuai dengan habitat tumbuhnya. Berdasarkan hasil kajian dapat disimpulkan bahwa karakter morfologi vegetatif dan generatif memiliki peranan penting dalam identifikasi, klasifikasi, dan analisis hubungan kekerabatan antarspesies famili Poaceae. Penelitian selanjutnya disarankan untuk melakukan pengamatan lapangan dan analisis anatomi maupun molekuler guna memperoleh data morfologi yang lebih mendalam dan akurat.

Abstract

This study aimed to determine the effect of using tap water, air conditioner (AC) water, and rainwater on root growth and mitotic phases in shallot roots (Allium cepa L.). The study employed an experimental method with a quantitative descriptive approach and a Completely Randomized Design (CRD). Shallot bulbs were immersed for 48 hours in three different types of water: tap water, AC water, and rainwater. Observations were conducted on root length and mitotic phases through microscopic examination using the squash method. Data were collected through direct observation and documentation of the observation results, then analyzed descriptively by calculating the average root length and the frequency of mitotic phases observed. The results showed that all treatments were able to support root growth and mitotic activity in the root meristem tissue of shallots. The best root growth was observed in the tap water and rainwater treatments, with an average root length of 1.8 cm, while the AC water treatment produced an average root length of 1.7 cm. Microscopic observations revealed that root cells in all treatments were predominantly in the telophase stage, characterized by the reformation of the nuclear membrane and the initiation of cytokinesis. Differences in mineral content among the water types were presumed to influence cell division activity and root cell elongation. Therefore, the type of soaking water affected root growth, although all treatments were capable of supporting the mitotic process in Allium cepa L.

Abstract

The use of effective sentences in scientific writing is essential for conveying ideas clearly and systematically. However, ineffective sentences are still frequently found in undergraduate thesis writing, reducing clarity and coherence. This study aimed to describe the use of effective sentences, identify dominant types of ineffective sentences, and analyze factors contributing to sentence ineffectiveness in theses written by Biology Education students at Universitas Negeri Medan. This research used a descriptive qualitative approach. Data were taken from four undergraduate theses and collected through documentation and note-taking techniques. The data were analyzed using content analysis involving data reduction, classification, presentation, and conclusion drawing. The results showed 24 ineffective sentences categorized into five types: word economy, structural balance, idea coherence, logical language use, and parallelism. Word economy was the most dominant 41.7%, while parallelism was the least frequent 4.2%. These findings indicate that students still need improvement in applying effective sentence principles in academic writing. Therefore, systematic language guidance and academic writing supervision are needed to improve students’ ability to produce clearer and more effective scientific writing.
