Published: April 2020

Local content is one way to promote local wisdom in a country. Indonesia, being a very big and plural country, has a tremendous local wisdom that can promote the country in many aspects: political, economic, cultural, and in the educational sector. One of the main issues in the local wisdom is the local content. This research is trying to investigate the local content found in the reading passages in the local English textbooks used in Indonesian high schools. The research shows that many local English textbooks do not include local content in their reading passages. The problem arises due to the fact that many authors and or publishers are not aware of the importance of such local wisdom in their textbook writing. Another problem is due to the hegemony of so called the ideology of political identity within one nation which affects the philosophy of textbook writing in the respected country. By doing the research, it is hoped that many Indonesian authors write the reading passages which promote the local content in order to highlight the local wisdom of the country to other countries in the world.

Authors: Ying Y , Ruomei F , Setiana SM , Darmawan
Published: April 2020

This study discusses the mastery of Indonesian affixes among Chinese learners. For Chinese learners, Indonesian affixes are difficult to understand because the addition of affixes to basic words can change the meaning of words and types of words. In addition, affixes in Indonesian also experience what is called sound fusion in affix letters and basic words. From the survey, respondents are not familiar with the prefixes of me-, ber-, di-, se-, ke-, per-, the suffix of -i, and the confix ke-an, per-an, se-nya. Therefore, at the time of prefix teaching, it should be stated that the sound fusion in prefix of me- will occur if the initial letter of the basic word has the sound of /a/,/e/,/g/,/h/,/i/,/u/,/o/,/k/. When explaining the prefix di-, the learners need to be shown a comparison form and meaning with the preposition di, so that the learner understands the different uses. As for learning prefixes and other confixes, the learners need to be provided with various examples and sentence exercises so that they are accustomed to the sound fusión in prefixes and types of words changes that are formed with the addition of the affix.

Both the building structure and infrastructure in Indonesia today has increased in line with the development of planning and design regulations. Learning from the past, the concept of planning and design continues to be improved to ensure the safety of the surrounding environment. The completed building needs to be evaluated for the development of the existing structure. In terms of examining the quality of the material on the existing structural elements, a test is divided into two types, namely destructive and non-destructive. In concrete destructive test was done by coring tests while for non-destructive test the Ultrasonic Pulse Velocity (UPV) test method was used, Brinell Hardness test was used in steel. In this case industrial building were built in the 1990s. The workflow refers to ASCE 41-17 including examining existing buildings which are divided into three tiers namely Tier 1: Screening, Tier 2: Deficiency-Based Evaluation and Retrofits, Tier 3: Systematic Evaluation and Retrofits. In this paper was limited only in tier 1. From the results in both the ASD and LRFD methods obtained data that some steel members that were reviewed need to be carried out further analysis at tier-2 level where It was needed to do retrofit.

Indonesia is one of the world’s biggest tobacco crop producers. By tobacco farmer, this plant is often even dubbed “green gold”. Madura Island is one of the best tobacco-producing areas in Indonesia. Tobacco is a significant trading crop in the eastern part of Madura Island, specifically in Pamekasan and Sumenep. The decline in tobacco yields is usually caused by pests and diseases that attack tobacco plants. Experts can easily detect conditions in plants (including tobacco) with their eyes, but this is very suitable and requires expensive operational costs when the size of the planting area is vast, and the distance of the planting area is far from the location of the expert. So that digital image processing techniques need to be applied to detect tobacco plant diseases earlier. By using data in the form of photographs of tobacco plant leaves, the condition will be identified. The method used in this research is GLCM (Gray Level Co-Occurrence Matrix) texture feature extraction, while CM (Color Moment) colour feature extraction and Naïve Bayes method are used for classification. The results of testing tobacco identification obtained the best accuracy of 82.2% for Pamekasan tobacco and 84.4% for Sumenep tobacco. The best results are obtained by using the colour feature extraction.

Before segmentation performed on potholes, road images is done first on the image smoothing. With the aim at the time of the next stage of the next process (segmentation) is expected to produce good accuracy. In this research, there will be a comparison of four smoothing methods consisting of lowpass filter, highpass filter, highboost filter and gaussian filter. The four smoothing methods applied to twenty pothole road image data that have been preprocessed using a combination of brightness and contrast methods. Comparative measurements of the four methods use the Means Square Error (MSE) value and Peak Signal to Noise Ratio (PSNR). Test results obtained from this research is the average value of MSE lowpass filter 68.12, MSE highpass filter is 569.99, MSE highboost filter is 838.54 and MSE Gaussian filter is 34.68. The average value of PSNR lowpass filter is 66.60 dB, PSNR highpass filter is 47.36 dB, PSNR highboost filter is 44.77 dB, and PSNR Gaussian filter is 75.94 dB. The measurement results obtained by the Gaussian filter method which is the best method for smoothing on potholes road images, because it produces the greatest PSNR value, and the smallest MSE value.

This research aims to determine the results of leachate sample testing and the efficiency of decreased Iron (Fe) concentration in the phytoremediation process using horsetail plants (Equietum hyemale) and the filtering process with zeolite, activated charcoal, and palm fibre. After testing a number of samples, there was a content of heavy metal Fe with a concentration of 7.20 mg/L. Wastewater quality standard for activities at the landfill area based on Regulation of the Minister of Environment No. 5 of 2014 concerning the quality standard of wastewater for businesses and/or activities that do not yet have a stipulated wastewater quality standard is about 5 mg/L. Based on previous research, the selection of types of horsetail plant used for phytoaccumulators is based on requirements as a plant that has high absorption and is resistant to various external influences. Based on data from the measurement of leachate samples that have been carried out experiments in leachate pond with phytoremediation processes and filtration media, it is obtained an efficiency decrease in the concentration of iron (Fe) by 54% of the total concentration of iron (Fe) leachate before the phytoremediation process. Utilization of horsetail plant in overcoming environmental pollution is expected to be developed into an environmentally, friendly and inexpensive alternative so that it can be applied optimally to the management of leachate in landfills.
