Abstract

The growth of Chili pepper (Capsicum chinense Jacquin.) is affected by biotic and abiotic stresses. Abiotic stress such as waterlogging increases the expression of ACS (1-aminocyclopropane-1-carboxylic acid synthase) enzyme. This enzyme plays a great role in the process of ethylene biosynthesis and encoded by multiple genes. Waterlogging causes hypoxia condition. One of ACS enzymes that responds to hypoxia condition is ACS2. The different respond to hypoxia stress among plant was assumed to be caused by a different structure of the ACS2 enzyme. This study aimed to identify and confirm the active site of Capsicum chinense Jacquin ACS2  using modeling and in silico docking. The result of the three-dimensional (3D) structure modeling showed 91% similarity of Capsicum chinense Jacquin ACS2 with the structure of the tomato (Solanum lycopersicum L.). The Capsicum chinense ACS2 confirmed five active sites that bind to the substrates asparagin396B, valine397B, thyrosine152B, threonine128B, and thyrosine92A.

Abstract

This study aims to enhance understanding of water pollution through the use of histology preparations as educational tools for the sub-topic of water pollution in Grade X high school or equivalent. The research employs a descriptive method with a skinative approach. Water pollution is defined as the introduction of organisms, substances, energy, and/or other components into water due to human activities, resulting in a decline in water quality that affects its intended function. Histology preparations serve as a medium to assess the condition of organisms' tissues in rivers. Histology is essential for studying the normal tissue structure of organs or other body parts, addressing both anatomical and physiological aspects. Under a microscope, tissue preparations allow for the study of normal and abnormal tissue structures. Quality preparations must meet two criteria: identification, from organ collection through to observation, requiring expert handling; and cleanliness, assessed by the absence of air bubbles and the overall cleanliness of the preparation.

Abstract

Rainfall is hydrology event that occurred seasonal in every year. There are two seasons occurred in Indonesia, dry season and rainy season. The analysis of rainfall characteristics plays a significant role to predict the rainfall occurrence and probability of flash flood. In this paper, rainfall analysis using Hydrognomon v.4.0 will provide hydrology data information, such as rainfall intensity and time series. The highest maximum rainfall of 526 mm (in 2010) has a return period of about 11 years. This means that rainfall of this magnitude can be expected to occur once every 11 years. The maximum rainfall of 425 mm (2013) has a return period of about 5.5 years, indicating a more frequent occurrence than the highest rainfall. Thus, it makes data trend rainfall with higher values tends to have longer return periods, indicating infrequent intensity. However, rainfall with lower intensity tends to have shorter return periods and occurring more frequently.

Abstract

Rainfall is an essential component of climatology that should be consistently analyzed over extended periods. Availability of complete rainfall data is one of the most important parts in relation to Hydrology and Water Resources. The ideal data is  that in accordance with what is needed. However, in practice, incomplete records are often encountered, this can be caused by several things, including equipment damage, employee negligence, equipment replacement, and natural disaster. This situation causes certain parts of the time series data to contain empty data, it is necessary to pay attention to the pattern of the distribution of rain and the surrounding stations. In this paper, there are three rainfall stations analyzed, these are BBMKG Region I, Sampali station, and Belawan station. Unfortunately, there are two missing rainfall data in 2001 and 2006 in Belawan station. Therefore, this paper uses the Normal Ratio Method and the Inversed Square Distance Method to complete the rainfall data and compare the two methods. From the result, there are different values from the two methods, the value is smaller using the Normal Ratio Method. It can be caused by the influence of distance factors on inversed square distance.

Abstract

The development of renewable energy technologies increasingly demands innovative, efficient, and environmentally friendly designs. Vertical Axis Wind Turbines (VAWT) are among the promising energy conversion systems suitable for urban and marine applications. However, aerodynamic efficiency and environmental adaptability remain key challenges. In contrast, the anatomical structures of plants particularly leaves and stems have naturally evolved to optimize interactions with airflow and sunlight, making them a rich source of inspiration for technological innovation. This article presents an interdisciplinary literature review exploring how principles of plant anatomy can be integrated into VAWT blade design to enhance aerodynamic performance and energy conversion efficiency. Through a comprehensive analysis of literature from mechanical engineering and plant biology, this study identifies key anatomical features such as surface curvature, venation patterns, and epidermal textures as having direct relevance to drag reduction, turbulent flow regulation, and lift enhancement. This review aims to open new directions for bioinspired design approaches in wind turbine development and strengthen the collaboration between engineering and biological sciences in advancing sustainable energy technologies.
