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.

Drought is a hydrometeorological disaster that significantly affects water availability and agricultural activities. Pesisir Selatan Regency has diverse topographic conditions that influence the level of vulnerability to drought, thereby requiring a comprehensive spatial analysis. This study aims to map drought risk by integrating slope steepness with other biophysical parameters using Geographic Information Systems (GIS). The data employed include slope maps derived from DEMNAS, rainfall data (CHIRPS 2024), soil types, land use, and river networks. The analysis was conducted through scoring and overlay methods to produce a drought risk map. The results indicate that areas with very steep slopes (>45%) have a high level of vulnerability due to surface runoff dominance and low infiltration capacity, particularly in Bayang Utara District. In contrast, flat to gently sloping areas dominated by rice fields and forest cover are relatively low-risk. Overall, drought risk in the region is classified into three categories: low, medium, and high. The resulting maps can serve as a basis for local governments in developing spatial planning policies, water conservation infrastructure, and disaster mitigation strategies that are more adaptive and sustainable.

Coffee is a plantation crop that has long been planted and cultivated in Lombok. Senaru Village, Bayan District, North Lombok Regency is the largest robusta coffee producing area in Lombok with 225 hectares of coffee land. One of the coffee processing places in Senaru Village is the producer of Ayah Senaru Fermented Coffee which still uses the dry sun method with a tool called a widik. This drying method has many disadvantages because it takes a long time, is very dependent on the weather and is unhygienic. The process of drying coffee is the main factor that can determine the quality of coffee, which is why there is a need for technology as a coffee drying medium that is capable of producing quality coffee. Handling after harvest can be improved by applying modern coffee drying technology, namely greenhouses. The aim of this activity is to increase partner profits through an IoT integrated coffee drying greenhouse (GEEOTI) which is able to streamline coffee drying time and produce hygienic coffee skin waste. The method applied is the creation of GEEOTI, socialization of its use and analysis of the impact on increasing partner profits. The results of the research are that greenhouses can have a positive effect in speeding up, flattening the drying process and improving the quality of coffee compared to conventional methods. The waste from the coffee skins produced also becomes more hygienic coffee waste so it can be used as cascara tea. This activity can certainly increase partner profits by up to 100%. The partner's income, which was initially only IDR 5,100,000, was able to become IDR 13,950,000 per month because with the use of GEEOTI there was an increase in the price of coffee and the addition of a by-product in the form of cascara tea from coffee skin waste.  

The use of technology is one solution in helping problems in various circles, both in the world of education and in companies. One of them is the application of an accounting information system to enter, process or report a company's accounting. This application can produce data processing quickly and accurately. This will of course save time and also reduce errors that occur when work is done manually. Like cooperatives, cooperatives must use an accounting information system so that work can be done quickly and accurately. PGRI Kosera's activities in Central Java are in the savings and loans sector. The savings and loan recording process at Kosera PGRI Central Java is not very effective, and because the recording process is repetitive, there is still too much risk of inaccurate and quick misinformation to be reported using Ms. Excel still requires previous data processing from bookkeeping, both deposits, loans and installments, resulting in delays in submitting reports to management. Therefore, in a computerized system that can process membership data, journals, savings transactions, loans and installments, reports made by the Kosera Pgri Cooperative will be valid in programming languages, especially in calculating installment interest costs and financial reports. From the results of the program created, data entry errors and interest calculation errors can be reduced, financial reports can be produced more quickly, and effective and efficient achievements can be achieved.
