Abstract

Mangrove ecosystems are located in coastal areas that are affected by the tides of sea. Mangrove forest acts as a green belt that protects the coast from erosion due to ocean waves or tsunami storms and traps sediments as accretionary activity. One of the processes that occur in the mangrove ecosystem that contributes the most to water fertility is the process of decomposition or destruction of mangrove litter. Litter destruction is part of the decomposition process stage that can produce important nutrients in the food chain through the productivity of the waters around the mangrove forest. The purpose of the study was to determine the rate of decomposition of mangrove litter in the Pariaman Mangrove Forest Tourism Park. This descriptive study was conducted from November 2021 -February 2022. This study used the litter-bag method to store leaf litter for which the rate of decomposition will be calculated. The results showed that the rate of decomposition based on the time of observation at the research station was different. At Station 1, the final dry weight value is smaller than Station 2 and Station 3, namely 0,26 gr/day at Station I, 0.9 gr/day at Station II, and 1,3 gr/day at Station 3.

Abstract

Ecoenzyme is a processed product from organic waste, water and sugar. Ecoenzyme can be a multifunctional liquid, especially in supporting plant growth. The nutrient content contained in ecoenzyme can encourage vegetative plants including the formation of chlorophyll in leaves. To support growth, various doses of ecoeznyme were given to land kale (Ipomoea reptans Poir). This study aims to determine the effect of the dose of ecoenzyme on the increase in leaf area of ​​land kangkung. This research was carried out from January 2022-February 2022 in the Plant Physiology Laboratory and Biology wire house of FMIPA UNP. This study used a completely randomized design (CRD) with 7 treatments and 4 replications. Consists of: P1 (control), P2 (0.5% ecoenzyme), P3 (1% ecoenzyme), P4 (1.5% ecoenzyme), P5 (2% ecoenzyme), P6 (2.5 ecoenzyme), P7 ( 0.3 POC). The data obtained were analyzed by variance (ANOVA) with DMRT further test. The results showed that the dose of ecoenzyme did not have a significant effect on the increase in leaf area of ​​land kangkung (Ipomoea reptans Poir).

Abstract

The germination process of expired rice seeds is quite difficult because the seeds have decreased in quality due to expiration. Rice seeds (Oryza sativa L.) expired require increased viability to increase their germination. One way to increase seed viability is to use an invigoration material in the form of KNO3 by adjusting the soaking time and the concentration of KNO3 used. This study aimed to determine the best soaking time and KNO3 concentration to increase the viability of expired rice seeds. This research was conducted at the Biology Laboratory, Faculty of Mathematics and Natural Sciences, Padang State University in May-June 2022. This study used a completely randomized design (CRD) with two treatment factors. The first factor is the length of immersion with 3 levels, namely 12 hours, 24 hours, and 48 hours. The second factor is the concentration of KNO3 with 5 levels, namely 0%, 1.5%, 2%, 2.5%, and 3%. Each treatment combination consisted of 4 replications. The parameter observed is the vigor index. The results showed that the treatment of KNO3 concentration had a significant effect on the parameters of the vigor index of expired Cisokan kuniang rice varieties. The immersion time had no significant effect on the vigor index parameter. The interaction between immersion time and KNO3 concentration significantly affected the vigor index parameter.

Abstract

The hydroponic system is one of the most popular forms of plant cultivation in recent times because it can produce higher and cleaner quality yields than using soil. The NFT hydroponic system is one of the most widely applied hydroponic techniques because of the easier way to control plants and water and nutrient needs can be met properly. The purpose of this study was to apply the Nutrient Film Technique (NFT) hydroponic system to water spinach plants and to determine the growth results produced in this hydroponic system technique using AB mix nutrition. The research method used in this study was an experimental method. with a qualitative descriptive analysis that is observing the comparison of the growth of kale plants per week through measurement parameters from aspects of plant height and number of plant leaves. Based on the results of the study, at the age of 18 days, kale plants resulted in the growth of plant height with an average of 13.6 cm and an average number of leaves of 5 leaves, thus proving that the NFT hydroponic system gave good results on the growth of water spinach.

Abstract

Herpetofauna comes from the word herpeton, which means reptiles. In the past, before the science of taxonomy developed, amphibians and reptiles were included as one group of animals because they were considered to be both reptiles. With the development of science, they are now two separate groups. Padang State University (UNP) as one of the leading universities in Padang City, West Sumatra, continues to strive to be the best university at the national and international level, by repairing and adding physical buildings and complementing existing infrastructure. One of them is the construction of new buildings in several faculties at UNP. This study aims to find out what herpetofauna exist in UNP and how diverse they are. This study used the Visual Encounter Survey (VES) method. The number of herpetofauna found in UNP was 270 individuals belonging to 7 families, namely Ranidae, Dicroglossidae, Bufonidae, Gekkonidae, Acrochordidae, Scincidae, and Varanidae. The species found were Duttaphrynus melanostictus, Hemidactylus frenatus, Odorrana hosii, Fejervarya cancrivora, Acrochordus granulatus, Eutropis multifasciata, and Varanus salvator. The dominance value in the Padang State University campus area shows the number 0.6415, the richness value is 1.6076 and the species diversity value is 0.7712.
