Abstract

The Padang Savana area of Bromo Tengger Semeru National Park (TN-BTS) is located at an altitude of 750-3676 m above sea level so that it has a high biodiversity with a distinctive vegetation character. Ferns (Pteridophyta) is one of the vegetation that dominates about 35% of the Bromo Conservation Area. The ferns in the location show a dry and dead physical condition. This study aims to analyze the causes of death of ferns (Pteridophyta) in the Padang Savana Bromo Tengger Semeru National Park. The research method used is a qualitative descriptive method and the data obtained from direct observation to the savanna of Bromo Tengger Semeru National Park (TN-BTS) and face-to-face interviews without guidance to resource persons. The sampling location is at an altitude of 2026 masl, temperature 24.4°C, air pressure 792.5 HPA, with the object of research in the form of a sprig of ferns (Pteridophyta) complete with dead leaf roots and is considered to represent all ferns (Pteridophyta) in the savanna. The data obtained from the resource persons were then analyzed using literature studies. The results showed that the death of ferns (Pteridophyta) was caused by several factors such as the presence of allelopathic substances produced from Imperata cylindrica, soil texture, and eruption disasters. Thus, the surrounding environment is very influential on the life of ferns (Pteridophyta) The results showed that the death of ferns (Pteridophyta) was caused by several factors such as the presence of allelopathic substances produced from Imperata cylindrica, soil texture, and eruption disasters.

Abstract

The program to build food security can be applied to several aspect such as food safety, food availability, affordability, and food distribution. The program is carried out so that humans can manage natural resources for the availability of food needs in a sustainable manner. One of the most important foods is fish. Fish contains high protein, omega 3 fatty acids, and other nutritional. The purpose of this study was to determine the potential of fish diversity in the Kedung Ombo reservoir as a provider of sustainable food needs. The research method uses survey and literature review. Based on the results of the literature study, it was found that there were 13 types of fish and came from 7 families. The fish species include parrot fish (Oreochromis niloticus), tilapia fish (Oreochromis mossambicus), Catfish (Pangasius sutchi), tawes fish (Barbodes gonionatus) and betutu fish (Oxyeleotris marmorata). In fish farming activities, one of them must be carried out properly, one of which is by paying attention to the concept of inland public waters in a sustainable manner so that its easy for the community to meet their food needs
