Synthesis and Characterization of Nanoherbal of Reed Root Ethanol Extract (Imperata cylindrica L) Using Ionic Gelation Method

/in /by

The purpose of this study was to determine the characteristics of nanoherbal of reed root ethanol extract (Imperata cylindrica L) and optimal variations of alginate and CaCl2 for the manufacture of nanoherbal of reed root ethanol extract. Nanoherbal are made using the ionic gelation method by mixing ethanol extract of reed root, alginate solution, and CaCl2 solution. There are three variations in the composition of alginate and CaCl2 solutions used, namely the ratio of 1: 6.66, 1: 3.33 and 1: 2.5. The solids in the nanoherbal colloids are separated using centrifuges. The residue is washed with aqueous and freeze dryer for 24 hours. Colloidal nanoherbal were characterized using PSA to determine particle size and potential zeta values. Nanoherbal solids were characterized using SEM to determine their surface morphological shape. The nanoherbal that were successfully made were faded yellow and white solids. The IR spectrum of nanoherbal shows absorption bands at O-H extended vibrations, C-O bending vibrations, and C=C bending vibrations that undergo shifting, as well as the emergence of manuronat fingerprint bond vibrations in the infrared spectrum supporting the formation of nanoherbal. Characterization using PSA showed a size of 186.2 nm at an optimal concentration ratio of alginic acid and CaCl2 of 1:6.66. SEM results show solids particles are not spherical, uneven, and in the form of loose aggregates on the surface.

Analysis of Electrical Submersible Pump With 120% Overload Setting Point in the SLN Area

/in /by

In the SLN field, there has been an increase in the setting point by 120% to optimize fluid production and minimize the production decline previously caused by a setting point of 110%, which resulted in temporary well shutdowns. Wells HFU01 and HFU02 in this area experienced shutdowns, suspected to be caused by overload in the electrical submersible pump. Overloaded pumps were identified through alarms originating from the switchboard on the surface, where the alarms were triggered by three cables connecting the switchboard to the motor of the electrical submersible pump. This study aims to determine the impact of overload setting point on wells HFU01 and HFU02, which have not shown improvement after the overload setting point adjustment. The research methodology involves analyzing pump failures due to overload in the electrical submersible pump in wells HFU01 and HFU02 located in the Sumatera Light North Area, which affects the well production. From this research, it is suspected that the wells that have not shown improvement after the overload setting point change may be caused by worn-out, aged pumps with low efficiency, and pump cavitation issues. Through this research, these issues can be addressed, leading to improved well production and run life of the electrical submersible pump, ultimately reducing pump failures in the wells.

Unveiling the Impact: How Legislature Size Moderates Budget Forecast Errors

/in /by

The Province of Aceh has recently gained attention as one of the poorest provinces in Indonesia. This situation is partly attributed to the failure to maximize the utilization of budget allocations, resulting in the loss of the intended benefits of the Regional Budget (APBD) for the public. Therefore, this research aims to investigate and analyze the influence of local revenue growth and expenditure growth on budget forecast errors, as well as the role of legislature size in moderating the relationship between local revenue growth and expenditure growth on budget forecast errors. The research employed a census method, covering the entire population, which consists of 23 regencies and cities in the Province of Aceh from 2018 to 2022. The study utilized Structural Equation Model-Partial Least Square (SEM-PLS) analysis with WarpPLS version 7.0. The findings indicate that local revenue growth has a positive impact on budget forecast errors, while expenditure growth has a negative impact. Furthermore, legislative size moderates the relationship between local revenue growth and expenditure growth concerning budget forecast errors. The study suggests that local governments should create clear and proportionate plans for regional revenue and expenditure budgets based on the region’s capacity. They should also optimize and expedite budget realization to ensure the implementation of all government programs and activities. Both local government leaders and the Regional People’s Representative Council (DPRD) also should establish comprehensive and transparent regional regulations regarding the DPRD’s Pokir proposal mechanism, from the planning process to accountability.
