Abstract

The palm oil production process yields crude palm oil (CPO) and palm kernel as its main products, along with byproducts such as empty fruit bunches (EFB), fiber, palm kernel shells, and palm oil mill effluent (POME). This study aims to analyze waste utilization and estimate the potential electrical energy that can be generated from these solid and liquid wastes at PT X. The analysis involves observation, measurement, data collection, and calculations based on mass balance principles. At PT X, EFB is incinerated, while fiber and shells are utilized as boiler fuel. POME is treated in open lagoons and used as liquid fertilizer for company-owned plantations. Based on daily operational data and calorific values, the estimated potential energy is 18,174,559.55 MJ from EFB, 7,538,070.26 MJ from palm kernel shells, and 2,125,525.40 MJ from biogas. With an operational time of 720 hours per month, PT X has the potential to generate 2.63 MW of electricity. The findings highlight the significant energy potential of palm oil waste. Therefore, further development of waste processing technologies is essential to maximize energy recovery, support internal energy needs, and potentially supply electricity to surrounding areas.

Abstract

This study evaluated the effect of moist heat processing (boiling, steaming, autoclaving) on the physical properties of Moringa oleifera seed flour to determine the optimal pretreatment for product development. Exotesta of moringa seeds were removed, subjected to the treatments, oven-dried, grounded, and sieved (60 mesh). Moisture content, color (CIELab), bulk density, and angle of repose were analyzed. Results showed that all treatments increased moisture content compared to raw seeds (4,36–4,46%), with no significant difference among treatments. Autoclaving produced flour with the highest bulk density (0,4258 g/cm³) and lowest angle of repose (33,37°), indicating better flowability. Color analysis revealed darker flour in autoclaved and boiled samples due to Maillard reactions. Overall, autoclaving is the most effective pretreatment for producing denser, free-flowing Moringa seed flour suitable for functional food applications.
