Abstract

Lactic acid bacteria (LAB) has been widely used as a starter culture. The most important factor fordeveloping industrial starter culture is the selection of a good and cheap medium. Tofu whey (TW) is the liquidwaste of the tofu production which potentially be able to use as a growth medium for LAB. On this research, TWwas fermented by Pediococcus pentosaceus E.1222 for 24 hour, at 37°C, pH 6, and without agitation. This workwas conducted in several stages, first stage was selection of carbon source and the result showed that TWsupplemented glucose gives the highest LAB number was 4.5×108 CFU/mL and spesific growth rate (μmax) 0.65h-1. The next stage was determining glucose concentration and the highest growth was TW supplemented 5%glucose, where the number of LAB reached 1.4×1010 CFU/mL and μmax 0.91 h-1. The next stage was scaling upthe starter production, fermentations were initially performed at scale 150 mL medium, then medium was scaledup to 500 mL and 1 L. The result showed a slight decreasing in number of LAB on each volume, from 1.1×1010CFU/mL (150 mL), 1.09×1010 CFU/mL (500 mL), and 1.03×1010 CFU/mL (1L); and declining of μmax is found tobe 0.91–0.90 h-1.Keyword: Lactic acid bacteria, starter culture, tofu whey, Pediococcus pentosaceus

Abstract

Since 2006, Indonesia’s CPO production has surpassed Malaysia’s to be the world largest producer.Nevertheless, Indonesia is evidently lower in productivity. The expectation for new plantation is relatively highdue to the constant increasing demand for CPO, especially for biodiesel related purposes. North Sumateraprovince as the pioneer in palm oil plantation in Indonesia has huge potentials to grow in the future, with theexisting plantation land of 12.71% out of total plantation land in Indonesia. The idea of setting up NorthSumatera as a benchmark in national palm plantation industry is not impossible. For that reason, the plantationrevitalization program should be carried out. The aim of palm oil plantation revitalization program is toincrease competitiveness mainly by increasing productivity. This can be achieved not only through plantationland extent but also by increasing the land productivity per hectare. Hence, it is crucial that the process toidentify all possible efforts in order to increase palm oil plantation productivity in North Sumatera be carriedout. Identification process might start by analyzing all factors affecting palm oil plantation productivity by usinganalytical network process (ANP). Potential factors that have huge impact to increasing land productivity aresuch as plant diseases, seeding, fertilizer selection, fertilizer dosage, appropriate tools and equipment used, typeof land, fertilizing frequency, working procedures, weeding control, pest control, fertilizing technology and seedfertilizing. Population per hectare and plant uniformity up to 31.5%, and fertilizing at 27.6% would contributeas the main factors to be closely monitored and observed further in order to increase palm oil plantationproductivity.Keywords: Palm oil agroindustry, plantation revitalization, productivity, the pioneer in palm oil plantation
