Air emission, generated by industrial sector, is one of the main contributors of ambient air quality degradation. In order to minimize the impact to its surrounding, the company regularly should conduct an air emission monitoring activity by measuring the hazardous compound concentration. The sample should be taken in a reference plane located two diameter from the outlet. The sampling of air emission by using isokinetic method cannot be conducted when the swirling flow is existed; the streamline is also should be uniform and vertical. Flow straightener with difference inclination angles, 0°, 15°, and 30°, are suggested to condition the streamline and fulfill the requirements. A computational simulation conditions with no flow straightener and with three flow straighteners are conducted to overview the influence of flow straightener inclination. Based on the analysis these inclinations are effectively improving the uniformity of velocity at reference plane. In other side these inclinations are causing the increasing of helicity as well as streamline inclination

Processing is done with a combination of crushing plant and excavator called concatenation of production system. Concatentation of the current production system is a concatenation between Komatsu PC300 excavator and 10 cm roll crusher dimension which produces 145,6701 tons/hour and takes 20,59 hours and is considered inefficient and ineffective to reach production target of 3000 tons/day. Based on the above, it is necessary to evaluate the concatenation of crushing plant production system so that the processing process will be optimally. The method used in this concatenation evaluation is the Analytic Hierarchy Process (AHP) method. The alternative is the concatenation between, Komatsu PC200 excavator - 10 cm roll crusher dimension, Komatsu PC200 excavator - 5 cm roll crusher dimension and Komatsu PC300 excavator - 5 cm roll crusher dimension. The selection of these alternatives is based on qualitative data (criteria from experts) and quantitative data so as to produce optimal choice. Based on the evaluation and analysis of the two types of data then selected concatenation excavator Komatsu PC200 - dimension roll crusher 10 cm which has a productivity of 207,8468 tons/hour and the time required to reach 300 tons/day for 14.43 hours.

To investigate the potential of adsorption and regeneration of natural pumice from West Sumatera Indonesia for total chromium (Cr) removal from aqueous solution, batch experiments in multiple adsorption-desorption cycles were performed. The results indicated that the optimum condition of total Cr removal were 3 of pH solution, 0.3 g/L of adsorbent dose, 60 min of contact time of adsorption, <63 ?m of diameter of adsorbent, and 1 mg/L of total Cr initial concentration with 2.226 mg Cr/g pumice of total Cr uptake. The experimental data obtained were fitted with the Freundlich adsorption isotherm within the concentration range studied. Desorption efficiencies for total Cr ions by using 0.1 M HCl as desorbing agent were in the range of 31-32%. Although complete desorption were not attained, the natural pumice could be sufficiently reused up to 3 cycles of adsorption- desorption with increasing trend in total Cr uptake that may due to the surface modification of natural pumice caused by HCl. Overall results revealed that easy availability of natural pumice as local mineral in West Sumatra, Indonesia and its ability to adsorb and retain total Cr will create more interest to develop new natural adsorption method of pollutant removal from solution

In order to improve a community composting system, three scenarios have set based on the critical points of initial system from sensitivity analysis result of Life Cycle Assessment of community composting system of agricultural and agro industrial wastes composting. Sensitivity analysis of initial system revealed two critical points that used as consideration on setting of improvement system scenarios. On initial system, composting process contributed the highest impact potency on acidification, eutrophication, global warming, and photochemical oxidation, while distribution was responsible for the highest impact on human toxicity potential. By comparison of initial composting system with three improvement scenarios, it found that the third improvement scenario (SC3) was the best scenario that recommended to be implemented. SC3 promoted application of compost blanket for gases emission reduction of compost pile, and substitution diesel fuel of pick-up with CNG fuel for transportation emission reduction. This scenario reduced impact of initial composting system by 29% with the highest impact reduction was on global warming potential by 54%.
