Abstract

Pineapples are often consumed by humans and produce waste from pineapple skin, but the content of pineapple skin has a water content of 81.72%, crude fiber 17.53%, carbohydrates 4.41%, protein and reducing sugar both have the same content of 13.65%. Usually Mexican people make pineapple skin as a fermented probiotic drink or also called tepache. With the fermentation process in this probiotic drink, of course there is the effectiveness of the Lactobacillus casei microbe which has the ability to inhibit pathogenic bacteria that have the potential in making tepache which is utilized from pineapple skin against sugar concentration. Using the Experimental research method is a systematic, careful, and logical study to control a condition. From making pineapple tepache will produce different tastes, colors, textures and aromas. The less sugar concentration, the more sour it tastes and vice versa. the more sugar concentration, the sweeter it tastes. This is because there is a percentage of lactic acid which will lower the low pH value at the sugar concentration in it.

Abstract

The yard of the house is an area of ​​land covered with various types of plants. Most of the plants in the house yard were deliberately planted by the owner. This research aims to manifest diversity and inventory types of garden plants in the homes of residents of RW 11, Kebonjayanti Village, Kiaracondong District, Bandung City. The research method used to obtain research data is an exploratory method. This research was carried out by exploring and observing directly the types of garden plants. Plants are identified using the help of the PlantNet application. Based on research data from the RW 11 area, Kebonjayanti Village, Kiaracondong District, Bandung City, 81 types of plants were found consisting of 40 families. The dominant family is the Araceae family.

Abstract

This research aims to describe and compare the morphological characteristics of spores in Thallophyta (lichens) and Bryophyta (mosses). The research was conducted at the Biology Laboratory of UIN Sunan Gunung Djati Bandung for one week. This study employed a descriptive method with macroscopic and microscopic observations. Samples of lichens and mosses were analyzed using a light microscope. The results showed that Thallophyta spores have asymmetrical morphology, are pale green, have a count of 15 spores, and are adaptive to extreme conditions. In contrast, Bryophyta spores are round and flat, with a reddish-brown capsule, and a larger number of spores, namely 67. These differences reflect the unique adaptation strategies of the two groups to their respective environments. Lichens, which are a symbiosis between fungi and algae, serve as indicators of environmental quality and grow on various substrates, including polluted areas. Meanwhile, mosses play an important role in maintaining soil moisture, preventing erosion, and supporting water and carbon cycles.
