Abstract

There is an indication of water pollution in Kalitidu River, Jelu Village, Kalitidu District, Bojonegoro Regency due to domestic and agricultural waste disposal activities.  The purpose of this study was to assessment of water quality index the Kalitidu River by conducting physical, chemical, biological and evaluation tests using SWOT analysis to control water pollution. This research employed quantitative descriptive and qualitative descriptive methods. The parameters tested included the physical (Temperature, TSS), chemical (pH, DO, BOD, COD, Total Phosphate, Nitrate, and MBAS) and biological (Phytoplankton, Zooplankton, and Total Coliform) elements. Kalitidu River water quality indicates that it is classified as lightly polluted, with a pollutant index value of 4.8 and with an average water debit of 2.198 m/s. The value of Phytoplankton Parameter is 24 Individuals/L whereas the value of Zooplankton is 10 Individuals/L. This reveals that the water quality is below the standards of river water quality and the water quality is included in Class II based on East Java Provincial Regulation Number 2 of 2008. From the evaluation of the SWOT analysis a recommendation was made to try to control the Kalitidu River, the initiation of PROKASIH (Clean River Program), building WDP (Waste Disposal Sites), and small group initiation to supervise and implement reforestation around Kalitidu River.

Abstract

High ecosystem diversity can control pest populations. Rice is a staple food that continues to be researched for interesting things. Indonesia is ranked 3rd for production at the international level. The research was conducted through a survey of plants and paddy fields with conventional application in Kasembon Malang. Standard chemical fertilizer and pesticide application were used in this field. A total of 5 diagonally determined soil sample points were used in this study. The dilution method was carried out for the analysis of entomopathogenic fungi which were then tested using the Koch’s Postulate method on Tenebrio molitor, then observed the symptoms and mortality of Spodoptera litura during the pathogenicity test. The diversity value also demonstrated a medium diversity. We conclude that an application of pesticides and chemical fertilizer according to recommended practices, are not negatively affect the diversity of entomopathogenic fungi. Aspergillus sp and Penicilium sp can cause death against Spodoptera litura.
