Abstract

The aim of this research was to analyse the use of different filter media at laboratory scale under a horizontal biofilter system treating tapioca starch wastewater (TSW) to improve the effluent quality that met the national standard. The completely randomized design was used in this study. A horizontal biofilter system was designed and filled with filter media, include sand, gravel, soil (entisol type), coconut fibre and bamboo plait, in each unit. Prior feeding to the biofilter unit, TSW was inoculated with Bacillus sp. N-09. The TSW flow rate was maintained at 6 l d-1 and operated for 1-month period. The results showed that the use of sand as filter media gave a better performance in improving the TSW effluent quality followed by gravel, coconut fibre, soil and bamboo plait. The horizontal biofilter system packed with sand filter media removed 98.53 % BOD, 98.71 % COD, 88.96 % TSS, and increased pH to 8.0.

Abstract

The acid hydrolysis and the heating of lignocellulosic waste from palm oil mills have caused irreversible damage to the natural environment and can create inhibitor compounds on hydrolysis, making the waste improper for fermentation media. In this study, an environmentally save hydrolysis was tested by heating it under high temperature which followed by enzymatic degradation. The objective of the present study was to determine the optimal reaction temperature and reaction time of hydrolysis for the production of xylose. Under the temperatures of 128 and 200°C with reactions time of 30, 45, and 60 min, the best result of hydrolysates were taken. Its hemicellulose, cellulose, lignin, water content (raw material), residual hemicellulose, reducing sugars, water content (hydrolysate) and xylose were analyzed. The results showed that the higher the temperature had resulted in the more reduction of sugar hydrolysis and the hemicellulose in the solid residue was slightly removed. Hydrolysis at the temperature of 200°C for 45 min had indicated a reduction of sugar yield of 17.71% (db). Biodegradation in enzymatic hydrolysis of xylose had increased by 113.79% at 24 -1.24 g xylose / 100 ml.

Abstract

This research is carried out in order to evaluate the working postures of seven workers withdifferent job categories at a garden maintenance service. These seven categories of works aredivided into 23 work elements. The aim of this research is to investigate the presence of work-related pain symptoms, find all risk related to poor working postures, and finally propose sets ofrecommendations for improvement of working methods. Nordic Body Map questionnaire is usedin the study to detect the occurrences of workrelated pain. Meanwhile, risk level assessment forworking postures was carried out by means of Rapid Entire Body Assessment (REBA) method.All the two applied on seven job categories of workers.The results showed that all workers observed experienced with pain symptoms both after and before carry out the work. According to REBA analysis, there are 82.6% medium level risk working elements, 10.9% high level risk, 4.3% very high level risk, and 2.2% low level risk. Recommendation for improvement of working posture was given for work element, namely fertilizer sowing(very high level risk), hedge trimming (high level risk), and pesticide spraying (high level risk).Implementation of these proposed improvements result on diminishing the frequency of occurrence and the level of risk on physical pain.

Abstract

Due to their importance in industry, dynamic demand lot-sizing problems are frequently studied.This study consider dynamic lot-sizing problems with recent advances in problem and modelformulation, and algorithms that enable large-scale problems to be effectively solved.Comprehensive review is given on model formulation of dynamic lot-sizing problems, especiallyon capacitated lot-sizing (CLS) problem and the coordinated lot-sizing problem. Bothapproaches have their intercorrelated, where CLS can be employed for single or multilevel/stage, item, and some restrictions. When a need for joint setup replenishment exists, thenthe coordinated lot-sizing is the choice. Furthermore, both algorithmics and heuristics solutionin the research of dynamic lot sizing are considered, followed by an illustration to provide anefficient algorithm.

Abstract

Dragon fruits are usually consumed by people directly or being processed into juice. Therefore,the major by-product of dragon fruits is the peel. As by-product, dragon fruit peels have higherantioxidant level than pulp especially for White Dragon Fruits (Hylocereus undatus). Thisresearch is carried out in order to evaluate the antioxidant level and sensory of dragon fruitpeel tea which produced through a partially fermented process. The objective of this researchis to investigate the effect of withering time and rolling time on antioxidant level and sensory ofdragon fruit peel tea. Withering time varied in 30, 60, and 120 min while the rolling timevaried in 10, 20, and 30 sec. 2, 2, diphenyl-1-picrylhydrazil (DPPH) assay showed that radicalscavenging activities of dragon fruit peel tea infusion increased with the longer withering timeand shorter rolling time. Likewise the total phenol content (TPC) assay demonstrated theamount of phenol increased with the longer withering time and shorter rolling time. Therewere found that the dragon fruit peel had 29.58% in proportion compared with the whole fruitand vitamin C content in the peel higher than that in the pulp. The longer withering time andshorter rolling time will increase the phenol total content, antioxidant activity, and thelightness color, but decrease the acidity degree of tea infusions. In addition, the withering timewas 120 min and rolling time was 10 sec had higher Antioxidant activity 41.19% and the totalphenol 55.93 mg/L.

Abstract

Fresh cut flower has characteristis such as perishable and short shelf life. Pulse treatment is akind of method that can prolong fresh cut flower’s shelf life. Pulse treatment is a postharvesthandling which is done by soaking the stem of flower into a solution containing nutrients(glucose and sucrose) and germicides. The objectives of this reseacrh were to determine the bestalternatives of pulse treatment and determine shelf life of fresh cut rose flower of eachtreatment. There were 6 alternatives, namely P 1 (5% sucrose+20 mg/l AgNO 3 ), P 2 (150 mg/lAgNO 3 ), P 3 (1,2% sucrose+0,2 mM STS), P 4 (5% sucrose+20 mg/l AgNO 3 +320 mg/l citricacid), P 5 (1,2% sucrose+ 0,2 mM STS+ warm water (40 0 C)), P 6 (5% sucrose+20 mg/lAgNO 3 +320 mg/l citric acid+warm water (40 0 C)). The parameters used for determining shelflife are color of petals (lightness and redness), moisture content, and texture of stem. As results,shelf life of P1 was 8 days, P2 was 6 days, P3 was 4 days, P4 was 6 days, P5 was 5 days, andP6 was 5 days. All of the alternatives gave longer shelf life than control (4 days). The bestalternatives was P1 with 8 days shelf life. Moisture content in that day was 78,313%, texture ofstem was 47,0603 N, lightness was 31,237 and redness was 46,942.
