Abstract

IstiPudjihastuti, Edy Supriyo, Retno Hartati, in this paper explain that the development of micro industries, in banana chip  micro industry to the  member of group which is culinary enterprise Pemalang speciallized is give suitable solution to  consument for giving natural culinary with high nutrition value independently and cheap. The development of micro  industries is circular activity that consist of briefing about the use of gelatse system in banana chip production by naturally and independently, the suitable tachnique of banana chip production, production of furnace completely by steack as pilot plan, assitancy when the producer makes snack in gelatse system. Moreover, the taste of snack more delicious, the market bigger.   Key words: micro industries banana chip

Abstract

Retno Hartati, Edy Supriyo, Muhammad Zainuri, in this paper explain that many salt industry is currently undergoing a inefficiencies process in the production system. Declining quality of salt from the salt ponds and lack of homogeneity in the iodine content of salt briquettes and much KIO3 wasted. So it is necessary to increase the iodine levels in salt. This activity aims to design, create and test a iodized salt machine with a capacity of 1-2 tons per hour and perform quality control on products. Community service activities have been successfully implemented by creating iodized salt machine. The process is done by means of iodized salt machine in the salt product becomes higher and meet ISO standards, in which prior to iodized salt machine the content of KIO3 is 0 ppm and become 50 ppm after using KIO3. Keywords : yodization, salt,screw, injection

Abstract

Edy Supriyo, Mountainous area of Kendeng is known rich with their natural resources, one of which is phosphate. Phosphate element in form of tricalsium phosphate is not dissolved in water therefore it needs to be activated become monocalsium phosphate which is able to be dissolved in the water and can be used for plant to strengthen their root. As activator in hydrolisa reaction is yeast Saccaromyces cereviceae . The result of present work revealed that activation could be done using yeast after being in peak population. Optimum cultivation of yeast using 14o brix molasses give population of 1.8x.107 colonies/cm2. The optimum phosphate (P2O5) concentration increnement happened in subtrate of yeast of 120 grms that is 3,06 %. Key words : Activation, Natural Phosphate Fertilizer

Abstract

Mice are the main reservoir in transmitting leptospirosis, which is an infectious zoonotic disease caused by pathogenic leptospira bacteria, so it needs to be controlled effectively. Mice control has been using traps or rodenticides. One of the pesticides available is permethrin and malathion, which has been used as an insecticide. The purpose of this study was to determine the effectiveness of insecticide formulas as rodenticides in killing field mice, house mice, and tree mice. In the research of liquid rodenticide formula, the concentration is 0.025; 0.050 and 0.075% of the active ingredients were tested for efficacy against mice. Data analysis in the form of descriptive. The results showed that the absence of mice that died from these three types of mice, which showed a dose of 0.075%, was too small for mice so that they only experienced seizures. So that further testing is needed to make the killing power more effective on mice.
