Abstract:

The selection of the right timing for the harvest of oil palm fresh fruit bunch (FFB) can affect the outcome of the palm fruit quality, which can further imply the quality of crude palm oil (CPO). Truly ripen fruits can boost the yield and quality of crude palm oil. The determination of fruit ripeness is done with an approach to estimating the time of the harvest cycle and the approximate number of palm oil fruits that are detached from their bunches (loose-fruit). The study aimed to investigate the exact harvesting time with variations in the number of palm oil fruits that loose at each addit

Abstract:

The ripeness of oil palm fruits is one of the key factors for crude palm oil qualities. Recently, electronic nose systems have been developed intensively for fruit quality assessment which relates odors to ripeness levels. This study developed an electronic nose system to characterize the ripeness levels of oil palm fruits using output voltage of each sensor and fruit hardness. The system consisted of a sensor chamber and a sample chamber. The sensor chamber consisted of eight MOS gas sensor modules of MQ series. Samples were oil palm fruits taken from oil palm fresh fruit bunches (FFB) which

Oil palm fruit theft at PT. Perkebunan Nusantara V still occurs frequently, especially in one district, Tandun District which has 6 oil palm and rubber plantations. The high rate of theft of oil palm fruit causes a decrease in the production of oil palm fruit and palm kernel. This study discusses the use of the K-Means Clustering algorithm as one of the data mining algorithms in grouping data on palm oil theft in the oil palm plantation area of Tandun District.

Abstract:

Threshing is the post-harvest handling stage after the harvesting process. Threshing is an integral part of the palm post-harvest handling process. The harvested oil palms are threshed to separate the fruit from the bunches. The threshing process is carried out so that small oil palm fruits or oil palm fruit bunches weighing below 5 kg can be accepted at the palm oil mill. Generally, the weight of fresh fruit bunches (FFB) under 5 kilograms is not sold, so before being taken to the palm oil mill, it must be threshed first so that the palm oil becomes brondolan or grains of palm oil that can be

The palm fruits were stored in a refrigerator for 0, 7, 14, 21, and 28 days after harvesting before analyzing their carotenoid content, DOBI, FFAs, moisture, and impurities. The results showed that the

Abstract:

Oil palm (Elaeis guineensis) is a species of palm tree cultivated mainly for its oil. Malaysia is the second largest producer of oil palm behind Indonesia. During the harvesting of oil palm fruit bunch, some over ripped fruits will get detached from the fruit bunch and these loose fruits will be contaminated with bacteria from the soil. Collecting the loose fruits from the ground is normally done manually by hand and this may allow the transmission of bacteria from the soil to the workers.  According to Table 1, this study reported on the microbial contents of the oil palm loose fr

Abstract:

Oil palm fruits farmers in Indonesia have determined the ripeness of oil palm fruits in the traditional way, namely using human eye visuals, which have the weakness of inconsistent levels of accuracy and are prone to errors. The development of increasingly sophisticated technology will help oil palm fruits farmers recognize the characteristics of fruit maturity. Advanced technology, such as frequency modulated continuous wave (FMCW) radar, can assist farmers in accurately identifying fruit maturity. To ensure high accuracy and sensitivity, an antenna with low side lobe level (SLL), high gain,

Palm oil is a very important commodity besides oil and gas which also has a fairly good export value. The palm oil produced must be supported by the quality standards set by SNI. The level of maturity when harvesting oil palm fruit greatly influences the quality of Crude Palm Oil (CPO) production, which is crude palm oil that has a reddish color obtained from extraction or from the pressing process of oil palm fruit flesh. In fact, in the field of oil palm fruit harvest, there are still many oil palm fruit that are not ripe enough and can even be said to be still raw, entering the CPO producti

This study shows that a 0.50% (v/v) ethephon application by the evaporation method induced the highest fruit detachment of 30.8 ± 1.1% after 24 h at room temperature, with the FFA content in the extracted crude palm oil at 0.34 ± 0.09%.
