Abstract

The problem of small handmade paper industry comes from the not yet optimal quan- tity and quality of products that ultimately impact on continuity. The production of this paper is subject to weather, material limitations and handmade paper making techniques that ultimately affect  product  continuity.  Consumers  of  handmade  paper  generally  craftsmen  also  want  pa- per that varies in the manufacture of paper products. The objective of the activity is to improve the ability of small industries to improve the quantity and quality of handmade paper and hand- made paper products. Implementation of science and technology in making handmade paper pro- duces 6 variants of paper made from single raw material or mixture of mendong, grass, waste paper and banana debog with synthetic and natural staining and pattern using various forms of leaves. The use of cutting tools that vary and sharp also has produced 6 types of paper boxes made from handmade paper, including a form that is quite difficult to make such as round, oval or heart shape. The manufacture of products for a certain amount has been mastered so that small industries are able to accept orders in a relatively quick time according to the needs of consumers

Abstract

The purpose of this study was to evaluate the effectivity of the leaf garbage composting process were given three different kinds of activators.The material composed are chopped leaf garbage and goat manure in the ratio of 3: 2, and make in three activators treatments. There are activators of orange peel waste, vegetable waste and EM4 product as a comparison. Compost is harvested after the composting process lasted for 21 days. The variables measured include (1) changes in daily temperature, pH, humidity compost during the composting process, (2) quality parameters such as physical parameters (texture, colour, odor, and depreciation), and chemical parameters (water content, pH, and C/N ratio). All of data were analyzed descriptively. The changes of daily temperature, pH, and humidity on EM4 compost activator treatment showed highest depreciation (39.3%) followed by compost with vegetable Mol and waste orange peel ( 31.6% and 29.8%), while the graphs of pH and humidity appear constant during this process. Accordance with the percentage of the depreciation, C/N ratio of the compost with EM4 activator showed the lowest (14.73). Generally, parameters of texture, colour and odor no different, as well as the water content and pH. This study concludes that composting treatment successfully and produce compost according to the criteria of SNI standard Number 19-7030-2004.
