Abstract

This training aims to increase the economic independence of housewives in RT 030 RW 007,Kalidoni Village, Palembang. The implementation of this activity is packaged interactively bypresenting lecturers from the Faculty of Engineering, University of MuhammadiyahPalembang. The form of service activities is in the form of decoupage technique training, thistechnique is a technique of beautifying ordinary items into good products, artistic value andhigher selling value. The material used is plain woven bag material which is then decoupagetechnique (from French which means cutting, decorating), affixed with motif tissue paper(napkin) followed by varnishing, will produce a beautiful woven bag. This skill is quite easy butrequires precision and gentleness because the tissue paper used is very smooth and easily torn ifyou are not careful in cutting, pasting and varnishing. Not only training, but in this activity,online business counseling is also held through the marketplace and social media. An effectivesolution for mothers of productive age but do not work outside the home. Overall, theimplementation of activities can provide new business opportunities for housewives.

Abstract

The aim of this research is to develop membrane material and analyse the membrane performance in liquid waste management of CPO industry to separate suspended solids. Conventional waste treatment has not been able to reach the minimum regulatory standards that have been set. Land area constraints and waste management techniques are complex and produce large sludge volumes. Besides specifically for managing liquid organic waste, the difficulty of the process of degradation of waste due to the high quantity and content of contaminants that can reach up to 40,000-120,000 mg / l for COD. In this study composite membrane made by titanium dioxide in the membrane polyvinylidene fluoride was blend very well and suited to remove suspended solids in the wastewater. The optimization result obtained is the addition of TiO2 2% produce maximum flux with the value of 180 L / m2.hr and the percentage of 92% fitration. The results of the filtration process conditions were the total suspended solids (TSS) by 99.63% and ammonium nitrogen (NH3-N) by 92.82% is the ABFR process conditions at 2.25 ml / min, HRT at 276.93 min, MLSS concentration at 4.50 g / L, and the pH at 6.50. So it can be concluded that titanium dioxide resulted the minimise of average poresize and enhance the hydrophilicity of membrane that resulted the maximum flux of this process.

Abstract

The amount of used cooking oil is increasing along with human activities. Used cooking oil that is disposed directly into the environment will give a negative impact on health and the quality of the environment, therefore it is necessary to purify the used cooking oil so that the used cooking oil can be reused. In this study, used cooking oil that has been used with heating time of 3 hrs, 5 hrs, and 7 hrs was used. The used cooking oil was purified using activated carbon made from 100 mesh bagasse with variations in weight of 2.5 g, 5 g, and 7 g, soaking time of activated carbon in used cooking oil were 24 hrs, 48 ​​hrs, and 72 hrs. The analysis used is the analysis of water content, free fatty acid content, and the amount of saponification. The results showed that the water content and saponification rate decreased with the length of contact time and the weight of activated carbon. The lowest free fatty acid content was produced when using activated carbon 7.5 g and contact time for 24 hrs.
