Abstract

The majority of the people in Labuhan Ratu VIII Village, Labuhan Ratu District, East Lampung Regency work as farmers, especially rice farmers. The inhibiting factor for production in this village is a disease that attacks plants during the growing season so that it becomes the main problem in this study. The main purpose of this research is to build an expert system application to help farmers solve farmer problems in diagnosing rice plant diseases based on Android. The data used in this study consisted of 7 diseases in rice plants, namely tungro, bacterial leaf blight (HDB), stem rot, midrib rot, blast, grass dwarf and leaf midrib blight. The method used in this research is the Forward Chaining Method. The method used to build an expert system application, the tracking process of this method is from the data, then match the data with the IF part of the IF-THEN rules. If it is in accordance with the existing rules, then the rules will be executed to get a conclusion. The results of this study, the application of an expert system using Forward chaining can be used to diagnose rice plant diseases with several steps, namely selecting symptoms, conducting consultations, and displaying the results of the consultation.

Abstract

Cow bone can be used as raw material of craft. Based on the development of science and technology cow bone can be utilized for many purposes, for example, it could be as an adsorbent. Cow bone can also be used as an activated charcoal, because bone contains about 35% of organic compounds. Activated charcoal was made of cow bone through carbonization and activation processes. The activation process used Na 2 CO 3 as an activator which the concentration is 2,5%, 5% and 7,5%. In this experiment, activated carbon of cow bone was used to adsorbed is cadmium, lead, nitrate and chloride ions in solution. Cadmium and lead were analyzed using atomic absorption spectrophotometer (AAS), while chloride was analyzed using Argentometry Mohr method and nitrate was analyzed using Brusin Sulfate method. The adsorption capacity of the activated charcoal cow bones to cadmium, lead, nitrate and chloride ions are 99.9643%, 99.9481%, 90.5885% and 10.145% respectively.
