Abstract

Data information that has been available is very much and will require a very long time to process large amounts of information data. Therefore, data mining is used to process large amounts of data. Data mining methods can be used to classify patient diseases, one of them is chronic kidney disease. This research used the classification tree method classification with the C4.5 algorithm. In the pre-processing process, a feature selection was applied to reduce attributes that did not increase the results of classification accuracy. The feature selection used the gain ratio. The Ensemble method used adaboost, which well known as boosting. The datasets used by Chronic Kidney Dataset (CKD) were obtained from the UCI repository of learning machine. The purpose of this research was applying the information gain ratio and adaboost ensemble to the chronic kidney disease dataset using the C4.5 algorithm and finding out the results of the accuracy of the C4.5 algorithm based on information gain ratio and adaboost ensemble. The results obtained for the default iteration in adaboost which was 50 iterations. The accuracy of C4.5 stand-alone was obtained 96.66%. The accuracy for C4.5 using information gain ratio was obtained 97.5%, while C4.5 method using information gain ratio and adaboost was obtained 98.33%.

Abstract

Liquid smoke can be obtained by condensing the smoke resulting from the pyrolysis chimney. Liquid smoke resulting from the pyrolysis process can be used as raw material preservatives, antioxidants, etc. Grade 3 liquid smoke is suitable for wood preservation and can also be used as a latex coagulant. In this study, it aims to determine what percentage of liquid smoke concentration is optimal for the preservation of meranti wood and determine the optimal soaking time of the meranti wood preservation process, the method used for the data retrieval process which is the measurement of acid content and the number of bacteria. The tool used is a series of pyrolysis tools. The acidity of meranti wood samples that are not soaked using liquid smoke is generally very high starting from 6±10, while for meranti wood samples soaked acidity levels are 5-6. The lowest bacterial mortality percentage (36.4%) control while the highest mortality percentage reaches 92%-100% indicated in the concentration of treatment. At a concentration of 25% able to inhibit bacterial attacks, it can be seen with a mortality percentage of 100% of all pyrolysis temperature levels. Liquid smoke retention at a concentration of 35% is the highest and more effective at immersion for 4 hours compared to the immersion of 3, 5, and 6 hours. Liquid smoke added to Meranti wood has toxic power to bacterial development. At a concentration of 35%, the average weight loss percentage of the test sample was 27.36%.

Abstract

The role of women in the economic field can be the main actor and this makes it one of the potential things in micro business activities. Developments in the digital era during the pandemic have encouraged Womenpreneurs to be able to develop their businesses and businesses by conducting online marketing.The digital economy is believed to be able to answer the challenges of developing economic development which until now has not been stable. This digital economy comes with many opportunities to answer existing problems. Based on the results of empirical studies, it was found that there are factors that encourage women to become womenpreneurs, namely: economic factors and independence factors.As the level of participation of womenpreneurs in the digital economy era progresses, there are also challenges, namely the gap in mastery of technology. Another form of problem is creativity and readiness to face digital change. Therefore, more womenpreneurs must be involved so that an increase in participation in digital economy education is needed

Abstract

Abstrak Penelitian ini bertujuan memetakan wilayah dengan risiko nilai percepatan tanah maksimum dan menganalisis kecocokan nilai metode perhitungan empiris dan data accelerograph pada kasus gempa di Mamuju 14 Januari 2021. Data yang digunakan adalah data kasus gempa di Mamuju 14 Januari 2021 magnitudo 5,9 yang diperoleh dari Badan Meteorologi, Klimatologi, dan Geofisika Stasiun Geofisika Gowa. Parameternya terdiri dari data waktu, lintang, longitudinal dan kedalaman, magnitudo dan percepatan tanah (gal). Perhitungan nilai percepatan tanah dilakukan dengan menggunakan persamaan metode Donovan, sedangkan untuk menghitung kecocokan nilai digunakan persamaan nilai persen error. Hasil dari perhitungan percepatan tanah diperoleh nilai percepatan tanah maksimum tertinggi diperoleh pada wilayah kecamatan Tapalang, Tapalang Barat, Simboro dan Mamuju, dengan nilai berkisar 196,50-261,66 gal. Sedangkan nilai percepatan tanah terendah diperoleh pada wilayah kecamatan Kalukku, Bonehau, Kalumpang, Papalang, Sampaga dan Tommo dengan nilai 41,76- 122,67 gal. Persentase nilai error terhadap data nilai percepatan tanah pada accelerograph bernilai 6%, hal ini menandakan bahwa metode ini dapat digunakan dalam menghitung nilai percepatan tanah maksimum dengan meninjau magnitude gempa ≥ 5 M. Kata Kunci: Data accelerograph, Donovan, earthquake, magnitudo, PGA. Abstract [Title: Analysis of the Fitness of PGA Value of The Donovant Method to Accelerograph Data (Case Study of the Mamuju Earthquake, 14 January 2021)] This study aims to map the area with the risk of the maximum ground acceleration value and analyze the suitability of the value of the empirical calculation method and accelerograph data in the earthquake case in Mamuju on January 14 2021. The data used is earthquake case data in Mamuju on January 14, 2021 with a magnitude of 5.9 obtained from the Meteorology, Climatology and Geophysics Agency of the Gowa Geophysics Station. The parameters consist of time, latitude, longitudinal and depth data, magnitude and ground acceleration (gal). The calculation of the ground acceleration value is carried out using the Donovan method equation, while to calculate the value match the percent error value equation is used. The results of the calculation of ground acceleration obtained the highest maximum ground acceleration values ​​obtained in the sub-districts of Tapalang, West Tapalang, Simboro and Mamuju, with values ​​ranging from 196.50 to 261.66 gal. While the lowest ground acceleration values ​​were obtained in the sub-districts of Kalukku, Bonehau, Kalumpang, Papalang, Sampaga and Tommo with a value of 41.76-122.67 gal. The percentage of error values ​​for the ground acceleration value data on the accelerograph is 6%, this indicates that this method can be used in calculating the maximum ground acceleration value by considering the magnitude of the earthquake ≥ 5 M. Keywords: Accelerograph data, Donovan, earthquake, magnitude, PGA.

Abstract

Bilebante is a tourism village which is rich with nature-based attractions and is one of the accredited-sustainable tourism villages in Lombok. One of the potential nature-based attractions in this village is the river. Hence, the preventive actions toward the negative environmental impacts of tourist activities should be implemented in early stage of its development. This community service is organised in order to empower the local people in Bilebante with nature-related tourism knowledge and skills for they can manage the river as a tourist attraction and as well as a conservation area. The local people’s enthusiasm to participate in this empowerment program indicate their strong willingness to develope a nature-based tourism attraction within the village and as well as the success of this community service program.
