Abstract

Water spinach (Ipomoea reptans Poir) is a commonly cultivated vegetable in tropical regions like Indonesia. Water spinach faces challenges related to water availability, which can impact various cellular, biochemical, and physiological aspects. Drought can lead to reduced vegetative growth, and a lack of water can inhibit overall plant growth. Therefore, understanding the growth response of water spinach to water stress is crucial for achieving optimal results. This study used a Completely Randomized Design (CRD) with water concentration as the treatment. Water spinach seeds were selected before being sown and transferred to polybags. Irrigation was conducted with five levels of concentration: 100% (300 ml of water), 75% (225 ml of water), 50% (150 ml of water), 25% (75 ml of water), and 0% (0 ml of water). Observations were made at 14 days old with agronomic and anatomical parameters, and the data were analyzed using MANOVA followed by a Tukey post-hoc test at a 5% significance level with SPSS. The results showed that irrigation with 300 ml and 225 ml of water produced the highest number of stomata and the longest stomata size. For stomatal width, treatments of 300 ml, 225 ml, and 75 ml resulted in wider stomata. Meanwhile, for stomatal area, the 225 ml treatment showed the largest stomatal size. However, no significant differences were observed in plant height and leaf number among the treatments. Drought stress affects photosynthesis and plant growth, with increasingly severe impacts as drought intensity rises. Drought results in reduced stomatal number, smaller stomatal size, and inhibited plant growth.

Abstract

Pendahuluan: Kemajuan biologi molekuler membuka peluang besar dalam riset genomik, berdampak luas pada bidang kesehatan, pertanian, dan lingkungan. Diperlukan peningkatan keterampilan sivitas akademika dalam pengoperasian alat laboratorium biomolekuler. Metode: Pelatihan dilakukan melalui pendekatan teori dan praktik langsung (hands-on training), dengan evaluasi menggunakan pre-test dan post-test untuk mengukur peningkatan pemahaman peserta. Hasil: Terdapat peningkatan signifikan pada skor post-test, terutama dalam penerapan alat untuk riset. Peserta menunjukkan peningkatan pemahaman, khususnya dalam aspek teknis penggunaan alat. Kesimpulan: Pelatihan ini efektif dalam meningkatkan kompetensi laboratorium peserta. Direkomendasikan pelatihan lanjutan dan pendampingan rutin untuk memperkuat keterampilan riset biologi molekuler secara berkelanjutan.
