Abstract The timing of harvesting oil palm fruit might affect the quality of the oil palm product. Mostly, The approximate number of palm oil fruits that have broken off from their bunches (loose-fruit) is usually used to measure the ripeness of fruit. The goal of this study was to establish the ideal harvesting period with variations in the amount of palm oil fruits that were loose from their bunches using two indicators: oil yield and carotene content. The variance was dependent on one factor: the number of days after the fruit was discovered unfastened from its bunch. The results showed tha

Oil palm crop yield is sensitive to heat and drought. Therefore, El Niño events affect oil palm production, resulting in price fluctuations of crude palm oil due to global supply shortage. This study developed a new Fresh Fruit Bunch Index (FFBI) model based on the monthly oil palm fresh fruit bunch (FFB) yield data, which correlates directly with the Oceanic Niño Index (ONI) to model the impact of past El Niño events in Malaysia in terms of production and economic losses. FFBI is derived from Malaysian monthly FFB yields from January 1986 to July 2021 in the same way ONI is derived from month

Oil palm smallholders, in particular non-plasma independent smallholders, experience significant yield gaps. Closing this yield gap is important to enhance sustainable livelihoods for oil palm smallholders and reduce the risk of yield increase through expansion. One of the key factors influencing yield is the harvest interval (number of days between two harvesting rounds). Although standards for Good Agricultural Practices regarding oil palm prescribe a harvest interval of 7-10 days, independent smallholders often maintain a harvest interval of 12-30 days.

In an effort to increase production, the plantation company aims to enhance production efficiency so that palm oil product prices become more competitive by determining harvest yields. The company's harvest yield estimation still uses a traditional approach based on the average bunch weight (BJR), considering the year of planting and the planting area. However, this technique is less effective and efficient. If the company's estimates are incorrect, it can po

Abstract:

In oil palm cultivation, harvesting is a task that demands the most attention, resources, and accuracy. The logistics of harvesting activities, from bunch cutting through delivery to processing, are organized as a function of yield per hectare, and this planning depends on production samples collected from plantations to estimate the number of fresh fruit bunches that will be harvested per crop management unit. Conventionally, production is estimated through sampling grids, most commonly every five rows and every five palms (5 × 5), 7 × 7, or 10 × 10. Sampling density, however, does not typica

Empty oil palm fruit bunches (EPFB) are the largest solid waste generated from palm oil mills. Accounting for 21-23 % of the total fresh fruit bunches. EFB ash contains K (Potassium) which can be recovered as K2CO3 through extraction. This research aims to recover K2CO3 from empty oil palm fruit bunches (EPFB) as a catalyst raw material because it is alkaline using the K2CO3 extraction method from the ash of empty oil palm fruit bunches (EPFB), which begins with a combustion process at a temperature of 700 oC to obtain ash. Ash extraction was carried out in 2 stages using water as a solvent. T

Abstract:

Water limitation has a major effect on agricultural crop production, influencing yield as well as external and internal quality parameters of table grapes. Due to their high yield potential, table grapes have a particularly high risk for yield and quality losses when water is limited, but grapevines are known for high heterogeneity within cultivars. Therefore, we investigated the effect of prolonged water deficits (control, moderate, and severe deficit) during fruit development on yield and quality parameters of four different table grape cultivars (Vitis L.).

This study aimed to a) investigate the morphological and physical characteristics of peat soils formed over sand and clay substrata and b) examine the relationship between peat soil substratum types (sand and clay) and oil palm production.
