Abstract

Bekri Business Unit is one of the palm oil factories owned by PT. Perkebunan Nusantara VII (Persero) located in Sinar Banten Village, Central Lampung. The processing capacity of the factory is 50 Tons/Fresh Fruit Bunches/Hour. However, since the 2014 – 2020 period, the average mill capacity was only 38.21 Tons/TBS. One of the problems faced is the lack of water supply for the treatment process, while the potential for managed water comes from ponds as reservoir that are available near the factory site. There are four existing ponds locations, while only one pond is operated because the other ponds have become sedimentation siltation. Thus, it is necessary to study the revitalization of the function of the ponds so that the volume of water storage can be increased. The calculation process used in this study was water balance concept by calculating the availability of water in ponds and water demand for palm oil processing plant. The results of data analysis and calculations show that the consumption of palm oil processing utilities into CPO in factory at the research site is 1.73 tons of water/FFB where normal conditions require 1.8 tons of water/FFB. The results of field measurements show that the existing pond number 4 capacity is 50,482 m3 with an average water level of 1.5 m in the pond. The storage volume is only able to fulfill the average production for 24 days per month so that it cannot meet the expected production target. Optimization efforts of the existing 4 location of ponds by returning the depth of the ponds to 3 m resulted in an average holding capacity of 207,686 m3 or an increase of 413.86% from the current pond capacity. Thus, normalization can increase the number of days of production due to the availability of the volume of water that can be used for production by 128,42% the average number of days of annual production and even the excess volume of water storage can be used for other needs.
