Abstract

. This research was conducted to identify differences in morphology and anatomy of betel leaves from the Piperaceae family and the Araceae family. In Warung Peuteuy Village, Cicalengka District, there are several species of betel leaves from the Piperaceaae and Araceae families which have different anatomical characteristics and leaf shapes. This study aims to determine the differences in terms of anatomical and morphological characteristics of betel leaves from the Piperacea family and the Araceae family. This research is descriptive in nature by explaining and describing the morphological and anatomical characters of 3 types of betel plants, namely green betel, red betel and ivy betel. Variations in the morphology of betel leaves from the Piperaceae family and the Araceae family can be observed from leaf type, leaf width, leaf length, leaf shape, leaf color, leaf edge, leaf tip, leaf base, leaf veins, petiole color, petiole length, surface, phyllotaxis. Variations in the anatomy of betel leaves from the Piperaceae family and the Araceae family can be observed from variations in the shape of ergastic objects, variations in the number of epidermis layers, number of hypodermis layers, number of palisade parenchyma layers, number of sponge parenchyma layers.

Abstract

This research explores the electrolysis process of a mixture of copper(II) sulfate (CuSO4) and aluminum sulfate (Al2(SO4)3) solutions using carbon electrodes. The main objective is to understand the mechanism of gas formation and metal deposition efficiency. In the experiment, CuSO4 and Al2(SO4) solutions )3 with a concentration of 0.5 M each is used as the electrolyte, and carbon electrodes as the cathode and anode. During electrolysis, the electric current causes copper ions (Cu²⁺) to move to the cathode, undergo reduction to copper (Cu), and deposit on them. cathode. Aluminum ions (Al³⁺) tend to remain in solution due to the higher reduction potential. At the anode, hydroxide ions (OH⁻) from water are oxidized, producing oxygen gas (O₂). and oxygen gas at the anode. The efficiency of copper deposition was analyzed by measuring the mass of deposited copper. This research provides insight into the dynamics of electrolysis of CuSO4 and Al2(SO4)3 mixtures, as well as their potential in electrochemical applications. In conclusion, the use of carbon electrodes is effective for the deposition of pure copper and the production of oxygen gas as a by-product.

Abstract

This research aims to determine the morphology of thallus lichen types as a bioindicator of air pollution in Cibiru. The method used is exploratory descriptive with survey techniques. Sampling was carried out at the Cibiru roundabout park which has a range of air temperatures and humidity levels, namely an air temperature of 28° and an air humidity level of 77.2%. The results of this research were that 1 type of lichen was found which belongs to the genus Dirinaria, namely Dirinaria applanata, with the characteristic of having irregular and folded lobes with relatively loose ends attached to the substrate, often containing rizines to help them attach to the substrate. The general morphology of the thalus found at the observation site tends to be round, elongated vertically, and irregular. The general morphological color of the thalus found is gray, bluish or almost white. Lichen can be used as a bioindicator for air quality tests, indicating air pollution. With the level of lichen diversity decreasing, the air quality is low.

Abstract

One of the materials in biology subjects is Virus where the material is abstract so it is difficult to understand by students and often when carrying out practicum in the laboratory also the results of studying on viral material are still much too low less than KKM which is 75. The purpose of this development research is to develop a virtual media laboratory viral material as a learning medium that facilitates teachers and students in the learning process that is expected to improve student learning outcomes. This research uses a type of R&D research with 4D models consisting of Define, Design, Develop, Disseminate in its development procedures. This research was conducted at SMA SHafta Surabaya by grade 10 of 30 students. Virtual Media Laboratory consists of the design of learning media that will be developed in the form of story boards on Virus materials developed with Adobe Flash CS6 software. Based on the assessment of material experts, design experts, media experts in a row by 100% , 84.28%, 87.14% which is declared very valid means that new products can be used in the field for learning activities. The results of the field trial assessment of 98.33% are declared very valid meaning that new products can be used in the field for learning activities. There was an increase in students' learning outcomes which was known by comparing the pretest and postest results of 46 and 85. The average improvement of student learning outcomes is 2.6 with high media effectiveness. In conclusion, virtual media laboratory can improve the learning outcomes of grade 10 students of SMA Shafta Surabaya on virus material.

Abstract

Indonesia is a tropical country, yet its highlands can produce one of the economically valuable types of subtropical fruit, one of which is the strawberry. Strawberry plants are highly profitable fruit plants and come in many variations. Their small and attractive shape, along with their sweet and fresh taste, make these fruits appealing. In Indonesia, strawberry farmers perform interspecies crossings, leading to the growth of many varieties. Indonesia, particularly West Java, is one of the environments suitable for strawberry growth, with Lembang in West Bandung Regency being a prime example. Therefore, this research aims to compare plant cultivars by combining the morphological characteristics of three varieties obtained from two locations, La Fressa and Bukit Strawberry, Lembang. The method used for identifying the diversity of strawberry plant characteristics is the FGD (Focus Group Discussion) method, which is then described specifically according to the morphology of the obtained plant varieties.

Abstract

Action to protect and preserve flora and fauna are through conservation. Gonocephalus chamaeleontinus, or forest dragon, is a protected species that is endangered. However, due to limited space, conservation of this wildlife is conducted ex situ in Bandung City. The habitat at the conservation site is designed to mimic its natural habitat. Despite clear differences in temperature and climate between its original habitat and the conservation area, this species can still thrive well. Furthermore, there are no signs indicating stress in these animals due to environmental differences as they have already adapted to the habitat in ex situ conservation.

Abstract

This research aims to provide an overview of experimental procedures to determine the correct price and solubility product (Ksp) as materials in introductory chemistry practical work. This research was preceded by an experiment to assess solubility values ​​and products, and then a descriptive analysis was carried out regarding the results obtained. Based on the results of the study, it is known that the steps for determining Ksp are (1) Calculating the mass of substances that can dissolve in a specific volume of solvent, (2) Calculating the mass of substances that can dissolve in 1 liter of solvent (solubility in g/L), (3) Calculating moles substances that can dissolve in 1 liter of solvent (molar solubility in units of mol/L), (4) Calculate the concentration of each ion, and (5) Calculate the Ksp of the compound from the concentration of each ion raised to the power of the reaction coefficient.
