Abstract

Corrosion is a decrease in the quality of a metal material caused by a reaction with the environment. Reducing the corrosion rate on steel can be done by adding an inhibitor. Papaya leaf extract (Carica papaya.L) can be used as a corrosion inhibitor by immersion method. The effect of inhibitor on corrosion rate had been studied using weight loss method, potentiodynamic polarization method, and observation of steel surface using photooptic. It was found that corrosion rate decrease with increase concentration of papaya leaves extract. The highest inhibiton efficiency is 87.8% in 0.2 M hydrochloric acid with 2% concentration of papaya leaves extract. Potentiodynamic polarization method showed that papaya leaves extract decrease corrotion current. Inhibiton efficiency reached 81.58% in 2% extract concentration in which corrosion current decrease from 0.0266 mA/cm2 to 0.0049 mA/cm2. Analysis of photooptic showed that there is difference on steel surface corroded in hydrochloric acid with inhibitor and without it.

Abstract

The rapid development of the palm oil industry, which cannot be denied, has an impact on the amount of industrial waste, particularly wastewater, requiring proper and effective treatment to reduce the impact of the damage. Wastewater treatment of Palm Oil Mill Effluent (POME) in an aerobic pond requires an adequate supply of oxygen so that its quality improves and becomes disposable, so it requires assistance from aeration media. A fine bubble diffuser was used as the aeration medium in this study. The aeration medium in this study was a fine bubble diffuser. The purpose of this research is to investigate the impact of installing a diffuser on the quality of the final wastewater, particularly the COD and BOD values, in the palm oil industry wastewater treatment. The analysis results for the wastewater parameters after the installation of the fine bubble diffuser revealed a significant reduction in the waste's COD and BOD values to 130 – 175 mg/L and 67 – 78 mg/L, respectively, making it more suitable for disposal to the environment.

Abstract

In this research, biogas is produced from Palm Oil Mill Effluent (POME) by fermentation of cow dung using a stirred reactor and purified by various CO2 and H2S removal techniques. The variables in this study were: composition of cow dung (55%, 60%, 65%, 70%, 75%, 80% w/w), amino acid composition (0.5%, 1%, 1.5% w/w) and length of fermentation time (2, 6, 10, 14, 16 days). The fixed variables were stirring speed (100 rpm), temperature (30oC) and reactor volume (100 L). This research also investigated the effect of using a lime packed reactor on the purity of methane gas. From the results of first stage of fermentation, it was found that the optimum composition of cow dung-POME was at 60% and the fermentation time was 14 days. In the second stage of fermentation using optimum results at first stage compared to fermentation of cow dung without POME, the results of measuring the gas pressure produced in 60% cow dung-POME fermentation were 17.5 Psig greater than fermentation of cow dung without POME of 15 Psig.

Abstract

One of the coffee producers in West Sumatra is the Solok Sirukam Sepakat Producers Cooperative, which has a business line called Agroforestry Unit focusing on coffee cultivation and processing. The brand name of the produced coffee is Solok Sirukam. The main issue currently faced by the cooperative is the storage of coffee beans after drying. So far, the beans have been stored in a disorganized manner on display racks. Additionally, the layout of the storage warehouse does not meet the applicable standards. Therefore, this activity aims to design a proper and adequate coffee bean storage rack to ensure the green beans meet storage standards. This will enable the coffee producers' cooperative to implement good coffee storage practices and produce beans according to proper processing standards. The result of using the newly designed storage rack shows a more organized arrangement. The rack includes tiered shelves with circular metal dividers, which allow for air circulation between the stacks of coffee beans, helping to maintain their moisture. The storage rack is designed to be tiered and columned, allowing for the storage of more coffee beans and grouping products with the same production code, facilitating easier retrieval for the next processing stage.

Abstract

The synthesis of a calcium glyceroxide catalyst derived from pensi shells for biodiesel production using crude palm oil (CPO) has been successfully conducted. The catalyst was prepared via the wet impregnation method by reacting CaO with glycerol in methanol as a solvent for 5 hours at 65°C, with catalyst-to-glycerol ratios of 1:1, 1:1.5, and 1:2. The glycerol used was obtained from crude glycerol, a by-product of biodiesel transesterification. CaO was derived from the calcination of pensi shells at 1000°C. The synthesized catalyst was tested for activity in biodiesel production from CPO. The test parameters included catalyst concentrations of 1.5%, 2%, and 2.5%, reaction times of 2 hours and 4 hours, and oil-to-methanol molar ratios of 1:5. The biodiesel yield for a 2-hour reaction time at catalyst concentrations of 1.5%, 2%, and 2.5% was 56.32%, 54.80%, and 50.19%, respectively. For a 4-hour reaction time at the same concentrations, the biodiesel yields were 40.28%, 60.73%, and 65.98%, respectively. Catalyst characterization was performed using XRD, XRF, SEM, and FTIR to support the activity test data. SEM analysis visually confirmed the bonding between CaO and glycerol. XRD results revealed the highest peaks at 2θ angles of 37.621° for CaO and 34.101° for Ca(OH)2, indicating a bond formation between CaO and glycerol. XRF analysis determined a CaO concentration of 96.21%. FTIR analysis identified the presence of glycerol through dominant -OH and C-O groups. The quality of the resulting biodiesel was tested against SNI (Indonesian National Standard) parameters. The analysis showed the highest methyl ester content (95.6%) at a reaction time of 4 hours. The highest oxidation stability (10.77 hours) was observed at a reaction time of 2 hours. Additional results included an acid number of 0.1%, total glycerol content of 0.279%-b, free glycerol content of 0.018%-b, and viscosity at 40°C of 3.559 mm2/s. The quality test results demonstrated that several parameters met SNI biodiesel standards.
