Abstract

Smart label is a label which could inform the quality and provide safety assurance of the food product.In this research, the label was produced from colored media and purposed to detect the growth of Salmonella.typhimurium. This bacterium is a pathogenic bacterium that causes salmonellasis disease with symptoms ofpoisoning type of infection. This bacterium is commonly appear in the fresh meat and meat product. The rapiddetection of this bacterium would assure the freshness and safety of the meat. This research was aimed toproduce the media based in color changing for rapid detection of the presence of S. typhimurium. The mediaindicator was produced from 2% (w/v) agar powder, 0.5% (w/v) tapioca starch, 1% (w/v) glycerol and 1% (w/v)selective media and then dissolved into distilled water until 100 mL solution. Four kind of selective medias wereused, i.e. Xylose Lysine Deoxychoalate agar (XLD), Hektoen Enteric Agar (HEA), Salmonella Shigela Agar(SSA) and Bismuth Salt Agar (BSA). XLD media was found to be a very sensitive media to the S. typhimuriumgrowth and presented a transparent color change to pink color that can be seen visually. The concentrationrange of 1-1.5% (w/v) of XLD was the best to develop the media. On the other hand, BSA and SSA media wasnotsensitiveon the S. typhimurium. Furthermore, another enrichment media of Brain Heart Infussion (BHI) withphenol red indicator has resulted in the rapid detection of 24 h after incubation compare to media without BHIin the same time. This media indicator gave in changing color from red to yellow.Keywords: media indicator, selective media, color changing, S. typhimurium

Abstract

Achievement of national palm oil industry as a producer and exporter of crude palm oil (CPO) in the world, it is now giving birth insecurity issues. This is because the growth of upstream and downstream industries of national palm oil that has not been balanced, which in turn encourages the national palm oil industry players to be oriented to the export of CPO which eliminates the added value in the country. On the other hand, though bring in foreign exchange for the country, but is prone commodity export orientation encountered a barriers problem in the international market. It is therefore important to provide a means of monitoring, prediction and assessment to facilitate the formulation of policies more about the marketing of national CPO industry. This research proposed the development of a model framework called adaptive threshold statistical control detection adaptive (SCDA) as a means of monitoring, prediction, and assessment of the movement of national CPO production volume. SCDA idea is to determine the dynamic threshold based mapping pattern historical data and predictions from the aspect of the frequency and trends. SCDA model adapted the techniques of statistical process control (SPC), while the values of the predictions generated from the simulation prediction model developed using the techniques of artificial neural network back propagation (ANN-BP) based on historical data of the national CPO production volume. The data used was the average volume of annual national CPO production period 1967 to 2015. The simulation results showed that the prediction model of national CPO production volume in 2016 until 2018 predicted were31.025 million, 32.214 million, and 34.504 million tons, respectively, while the values of maximum and minimum threshold that was formed in the model predictions SCDA for the period 2016-2018 each sequence were 33,322,065 and 29,246,547, respectively. As far as the literature search results, modeling SCDA has never been done in the research included for monitoring and prediction of national production volume of CPO. Therefore, research on the modeling of SCDA was contributing both to the development of knowledge about modeling as well as in the management of the national supply of CPO.Keywords: adaptive threshold, modelling, artificial neural network, palm oil

Abstract

Tempoyakis one of traditional food that has short shelf life. The pasteurization and packaging improvement could be expected can maintain the quality and extend the tempoyak’s shelf life. This research used polyethylene terephtalate (PET) and polyamide as packaging materials; with modified atmosphere packaging (MAP), non MAP, vacuum and non vacuum. The parameters quality of tempoyak were observed by value of pH, sugar content, lactic acid, alcohol, lactic acid bacteria growth and total plate count. The result showed that the best quality of tempoyak was produced by product with pasteurization treatment. Lactobacillus genus with L.plantarum, L. casei, and L. fermentum were the dominant species of lactic acid bacteria. The result also showed that after the tempoyak was fermented during 84 hours, then the pasteurization should be conducted to stop the fermentation. The 84th hours was a constant phase in which that was the right time to inhibit the acid lactic bacteria growth. Pasteurized tempoyak packaged in PET with MAP technique had the longest shelf life as much as 84 days than others treatment whose had aboutonly 14 untill 56 days. The decreasing of tempoyak quality at 84 days was showed by colour change of tempoyak from yelowness to brown, pH decreased from 3.97 to 3.73, lactic acid content decreased from 1.49% to 0.99%, sugar content decreased from 16.57% to 3.28%, alcohol content of 0.32%, number of lactic acid bacteria decreased from 174.3×104cfu/g to 8.6×102 cfu/g, and total plate count from 177×104 cfu/g to 182.3×103 cfu/g.Keywords: modified atmosfir packaging, pasteurization, tempoyak, vacuum

Abstract

Solid  waste from beltpress machine in wastewater treatment plant is produced as much as 1,25 tons/day but hasnot been utilized, causing unpleasant odour and requires a high cost for disposal. Composting is one of alternative technology that can be applied to solve the problem. The objectives of this research were to examine the influence of the initial C/N value and aeration rate to the rate of co-composting process in reaching the C/N value that corresponds to SNI 19-7030-2004, and to characterize the compost produced. The research design used was factorial Complete Random Design (CRD) with two factors and two repetitions. The first factor was C/N value, consisted of 25; 30; 35 and the second factor was aeration rate, consisted of 0; 0,4; 0,8 L/min.kg of dry material. Composting was done using 30 L reactor by giving active intermittent aeration for 1 hour/day during the first 7 days of composting. Effects of initial C/N value and aeration rate were significantly different (P<0.05) in the increase of temperature and the decline of water content and C/N value, but were not significantly different (P>0.05) on pH value. Lower initial C/N value and higher aeration rate attained standard C/N value fastest. The best treatment based on the conformity with SNI 19-7030-2004 was initial C/N25 with aeration rate 0,8 L/minute.kg dry matter. The compost produced met the SNI standards in macro elements, trace elements,and other elements, but didnot qualify the pH value and moisture content.Keywords: aerated static pile, beltpress solid waste, co-composting, rice straw

Abstract

Deterioration of bleachability index (DOBI) is one of the parameters in the refining process, to meet the quality of commercial crude palm oil (CPO); Miixing between high quality CPO and low quality CPO sometimes were undertaken. This study was conducted to assess the effect of dose of bleaching earth (BE) and time of bleaching process of various CPO quality, especially CPOs that had different DOBIs. The raw materials used were CPO with DOBIs of 0.65 to 4.80 which obtained from different raw materials, namely of fresh fruit bunches (FFB), palm oil mill (POM), waste from POM, and CPO from FFB heated at 120°C (during 30 and 60 minutes) and mixed with low quality CPO (ratio of 6:4 and 1:9). CPOs were bleached using BE doses of 0.5%, 1.0%, 2.5%, and 2% and time for 15, 30, 45, and 60 minutes. The results obtained from preparation of raw materials were CPO with DOBI of 3.9 and 4.8 (CPO from FFB 1 and 2), 1.4 and 2.68 (CPO from POM 1 and 2) and 0.85 (CPO from waste POM 2) as well as 2.5 and 0.65 (heating) and 2.92 and 1.52 (mixing). The warming of CPO caused colour, carotene, and water content decreased, while free fatty acids (FFA) and peroxide value (PV) increased. The more CPO low quality mixed to CPO high quality caused carotene and DOBI decreased while colour, moisture content, FFB, and PV increased. The results of bleaching showed that increasing time and dose of BE caused colour, carotene, DOBI, and water contents decreased, while FFA increased. PV decreased with increasing doses of BE and for 30 minutes PV decreased then increased with increasing time. Bleaching process of CPO from mixing between high quality CPO and low quality CPO might increase FFA, despite the mixture resulted CPO had high DOBI. This would impact on the deodorization process.Keywords: crude palm oil, bleaching, bleaching earth, deterioration of bleachability index
