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

Kemampuan minyak atsiri dari batang Amomum apiculatum sebagai insektisida alami telah diuji terhadap lalat Drosophila melanogaster. Uji yang dilakukan meliputi meliputi uji mortalitas, antifeedant dan repelan. Konsentrasi minyak atsiri untuk pengujian berturut-turut adalah 0; 0.1; 0.5; 1 %. Didapatkan persentase mortalitas tertinggi pada hari kelima yaitu 0; 0; 17.80; 35.53 %. Persentase antifeedant berturut-turut berdasarkan konsentrasi adalah 93.81; 94.07; 95.29; 96.61 %. Sedangkan persentase repelan berturut-turut adalah 4.46; 40; 60; 73.33 %. Minyak atsiri batang Amomum apiculatum juga menghambat proses regenerasi lalat, dibuktikan dengan adanya telur dan pupa pada kontrol pada hari ke-5, dan sebaliknya pada media dengan minyak atsiri sehingga dapat dari penelitian ini dapat disimpulkan minyak atsiri batang Amomum apiculatum berpotensi sebagai insektisida alami.

Abstract

PT Bukit Muria Jaya is a company engaged in the manufacture of cigarette paper which has good quality paper, has a white color and low tear strength. The process of making cigarette paper carried out in PT Bukit Muria Jaya Laboratory has several stages of the process starting from taking raw materials in PM (paper machine) 1, mixing with starch, printing process, pressing process, and drying process. At the time of making cigarette paper using pulp of the NBKP and LBKP types. The shed paper that is made will be tested for the specified physical parameters such as grammature, tensile strength and permeability. In this research, cigarette paper will be made without using a CaCO3 filler with NBKP: LBKP variations are 35: 65, 45: 55, 55: 45, 65: 35, 75: 25, 85: 15, 95: 5%. The results showed that all variables used did not meet the desired physical properties of cigarette paper.

Abstract

Clay Bath is a tool to separate palm shells from Kernels using a calcium carbonate solution. Kernel Losses in the Clay Bath unit are a problem that can be detrimental to CPO Processing Industry. The effect of the density of the calcium carbonate solution can reduce the Kernel Losses. In this study, variations in the density of calcium carbonate solution were made starting from 1.092; 1,112 ; 1.136 ; 1.142 ; 1.150 g/mL. Based on the results of the study, the lowest Kernel Losses were found at a density of 1.150 g/mL with 2.57%.

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 cassava processing businesses that are mostly carried out by the community in Agam Regency, especially in Kamang Magek District is making cassava crackers or better known as Kerupuk Kamang. This cassava crackers business is usually managed by the Home Industry or Small and Medium Industry groups. The marketing process currently carried out is by selling the production of cassava crackers to traditional markets and local distributors, besides that the cassava crackers sold are still in the form of kilos and do not have attractive packaging so that the selling price of cassava crackers is lower. This has an impact on the profits obtained by MSME in the Kamang Magek District, Agam Regency to be small. So that in order to get more profit or income, these MSME must be able to develop marketing and packaging of their products so that more markets can be reached. For this reason, it is necessary to provide briefing/counseling on how to carry out a good marketing strategy, in addition to providing knowledge related to the packaging process that can attract the attention of consumers. As a result of this activity, the community gained new insights regarding good marketing strategies to increase revenue and attract customers, such as making products of various flavors, using product labels/product brands, attractive packaging, promotions with social media and P-IRT permits.
