Abstract

With the emergence of the Peduli Protect application, which is used by the government to monitor the spread of Covid-19 in Indonesia, it turns out to be reaping the pros and cons of public opinion on Twitter. From this phenomenon, a research was conducted by mapping the sentiment analysis of twitter users towards the Peduli Protect application. This study aims to compare two classification algorithms that are included in the supervised learning category. The two algorithms are Support Vector Machine (SVM) and Naïve Bayes. The two algorithms are implemented in analyzing the sentiment analysis of twitter user reviews on the Peduli Protect application. The dataset used in this research is tweets of twitter users with a total of 4,782 tweets. Then, compared to how much accuracy and processing time required of the two algorithms. The stages of the method in this research are: collecting data from user tweets with a crawling technique, preprocessing text, weighting words using the TF-IDF method, classification using the SVM and Naïve Bayes algorithm, k-fols cross validation test, and drawing conclusions. The results showed that the accuracy of the SMV algorithm with the k-fold test method was 86% and the split 8020 technique resulted in an accuracy of 79%. Meanwhile, the Naïve Bayes algorithm produces an accuracy of 85% with k-fold, and an accuracy of 80% with a split 8020. From these results it can be concluded that both algorithms have the same level of accuracy, only different in processing time, where Naïve Bayes algorithm is faster with time required 0.0094 seconds.

Abstract

Mining industry activities have a very high dependence on fuel consumption. This dependence on the use of fuel is because diesel fuel is the main energy source to drive vehicle activities in the mining industry. Fuel consumption of PT. Arutmin Indonesia Tambang Kintap is around 40% of production costs. Given this substantial fuel demand, improving fuel efficiency is crucial, making fuel-saving measures essential. One approach to reducing fuel consumption involves adding bio-additives to enhance the fuel combustion process. The purpose of this study was to determine the effect of adding Grinzest bio additives to the fuel used by heavy machinery at PT. Arutmin Indonesia Tambang Kintap. The research steps include: (1) characterization of the fuel and bio additives; (2) blending fuel with Grinzest bio additives; (3) characterization of BBM-Grinzest blending; (4) testing the performance of Grinzest bioadditives on heavy machinery. The results of the study showed that Grinzest bio additives were able to reduce fuel consumption, reduce gas emission levels, and prevent rust (deposits) on the engine. The results of tests conducted by the team in the field showed that the addition of bioadditives to fuel with a ratio of 1:1000 showed a decrease in fuel consumption of around 7.4%.

Abstract

Since the onset of the industrial revolution, fuel oil (BBM) has served as the primary energy source. In Indonesia, there was a 10 percent increase in fuel consumption in 2016, reaching 48.6 million m3/year compared to the previous year, 2015. However, this rise in fuel usage hasn't been matched by an increase in Indonesia's oil reserves, which are estimated to deplete by 2050. With limited fuel reserves and mounting concerns about global warming and environmental pollution, extensive exploration into renewable and sustainable alternative fuels has been undertaken. Various researchers have proposed solutions, one of which involves incorporating additives derived from abundant non-edible natural resources in Indonesia, such as essential oils. Essential oils are extracted from plant parts using diverse techniques. These oils possess a low vapor point and are soluble in diesel fuel. Moreover, they contain diverse chemical compounds with oxygen atoms, enabling them to enhance the combustion process in diesel engines. Acting as bioadditives, essential oils augment the quality of diesel fuel. Fuel additives, which are substances added to fuel—especially gasoline or diesel—aim to enhance fuel properties, leading to improved performance. Their incorporation can reduce detrimental emissions like hydrocarbons (HC), particulate matter, CO2, and NOx emissions. Furthermore, they aid in increasing fuel viscosity, anti-knock properties, octane and cetane ratings, as well as improving cold flow characteristics, thermal stability, cleanliness, and preventing engine corrosion. Research outcomes indicate that essential oils can decrease diesel fuel consumption, lower gas emissions, and safeguard engines from rust deposits. Citronella essential oil stands out as a potential bioadditive due to its main compounds—citronellal, geraniol, and citronellol—that contain oxygen atoms. PT Arutmin Kintap has supported local farmers and distillers by cultivating citronella on 10 hectares of former mining land. Their plan involves utilizing the produced citronella essential oil to create the Z-fract Formula as a Bio-additive for industrial machine efficiency, collaborating with the Indonesian Islamic University (UII). The Z-fract bio-additive formula is specifically designed for PT Arutmin's industrial machines. Key strategic actions include: (1) Conducting workshops for essential oil farmers on proper planting techniques aligned with Good Agricultural Practices (GAP) to ensure raw material availability and production of citronella essential oil meeting SNI standards; (2) Characterization of citronella oil produced in Kintap; (3) Fractionating citronella essential oil; (4) Analysis of the chemical composition of the citronella oil fraction.
