cANT WUM : Web User Classification using Ant Colony Optimization Algorithm
Get PDFWeb Usage Mining (WUM) is the use of data mining methods to extract knowledge from web usage data. One function of WUM is to support Business Intelligence (BI) purpose in which one of the important information needed is the classification of web users that can be used for acquisition, penetration, and user retention activity. There are two main problems encountered in conducting the classification of web users. The first is the determination of antecedent attributes as a term of classification rules, which is a major problem in data mining classification function in general. The second problem is the preprocessing activity which involves preparing the supporting data for the web users’ classification need which is the most difficult stage in WUM. For the web user classification method, we propose a classification method based on ant colony optimization method (ACO) as a distributed intelligent system using heuristic function which is in line with the problem areas. We proposed a heuristic functions for web user classification based on web usage data that uses entropy of antecedent candidate, information gain from attribute of total number of web user access and average of access duration of web user. For preprocessing purpose, a method of data preparation that can support the needs of web users’ classification is proposed. The data used consists of web access log data, web user profile data and web transaction data. The preprocessing activity consists of parsing, data cleansing, and extraction of the web user sessions using heuristic method concerning web page access timeout and differences in web browser agent. Testing is done by comparing the performance of the proposed algorithm with Ant-Miner algorithm, cAnt-Miner algorithm, and the Continuous Ant-Miner algorithm. The results of testing of four web data shows that the performance of the proposed algorithm is better in terms of accuracy of rules and simplification of rules

Elementary school students who experience learning difficulties need help from teachers because it disrupts the learning process and affects learning success. This research is in the form of descriptive research with the aim of describing the implementation of diagnostics for learning difficulties by teachers. The subjects in the research were 23 elementary school teachers spread across four sub-districts of the city of Salatiga, both public and private elementary schools. The variable of this research is the implementation of the diagnosis of students' learning difficulties by elementary school teachers. This research method is in the form of a survey, collecting data on the implementation of the diagnosis of learning difficulties for elementary school students in the city of Salatiga. Data collection used a questionnaire supplemented by interviews. The analysis technique used is descriptive qualitative. The research results found that all teachers had carried out diagnostics for learning difficulties, and there were always students who experienced learning difficulties. Students' learning difficulties are more related to academic activities. Diagnostics of learning difficulties is carried out at the end of learning, using observation and learning results tests, as well as interview guides. The learning difficulties experienced by students in elementary school are predominantly in the form of Mathematics and Indonesian language subjects. Almost all teachers identify students' learning difficulties and determine the factors that cause their learning difficulties. The assistance provided by teachers to deal with students' learning difficulties generally takes the form of assisting students' learning and providing additional study time (tutoring) to students, as well as providing advice or referrals to parents to consult with experts. Barriers to carrying out diagnostics for learning difficulties in general are that complete diagnostic instruments for learning difficulties are not yet available, and teachers are not yet skilled in using diagnostic instruments for learning difficulties
KEMAMPUAN PEMAHAMAN KONSEP MATEMATIS SISWA PADA PEMBELAJARAN MODEL RME
Get PDFThis research aimed to produce a study of students' mathematical concept understanding abilities in classes with Realistic Mathematics Education (RME) model learning and classes that did not receive RME model learning. This research was a quantitative method of quasi experiment model designed in the form of non-equivalent control group design involving two research classes determined using purposive sampling technique. The instrument used was a test of students' mathematical concept understanding ability in the form of description questions. The data analysis technique in this study used an independent sample t-test and N-gain score. The results of the analysis showed that students' mathematical concept understanding ability in the class that received RME model learning was better than that of those who did not receive RME model learning. The increase in students' mathematical concept understanding ability in the class with RME model learning was in a low category with an average gain score of 0.025. The low increase is due to the limited learning time at school during the adaptation period of new habits, so that learning with the RME model does not run effectively

PHYSICO-CHEMICAL ANALYSIS OF GINGER OIL EXTRACTION WITH ADSORBED USED COOKING OIL AND ITS UTILIZATION AS TRADITIONAL MASSAGE OIL
Get PDFUsed oil is a commodity that can be sought to increase its economic value, one of which is used as an absorber of essential oil from ginger. Ginger has essential oils as anti-inflammatory, but the oil obtained is relatively small and volatile so that it reduces the healing effect. Used oil has the potential to be a massage oil and ginger oil adsorbent to be used to treat inflammation. On the other hand, leaf waste can be converted into activated charcoal which is used as an adsorbent for the treatment process of used oil. The aims of this study was to determine the physicochemical properties of used oil obtained from the extraction process of ginger rhizomes with adsorbed used oil. The method used was the treatment of used cooking oil by adsorbing it using activated charcoal from activated leaf waste. Used cooking oil was then used for solvent extraction of ginger oil content to conduct organoleptic tests, physicochemical properties, inflammatory tests and GC-MS analysis to see the content of the resulting used oil. The results showed that the ratio of ginger to adsorbed used cooking oil with the highest anti-inflammatory effect was at a ratio of 1:1 with good organoleptic results, gingerol content of 11.6%, camphene 3.75% and eucalyptol 6.79 resulting in an antiinflammatory effect close to pure ginger oil of 59.18% with a contact time of 4.55 hours and reaction order 1

Implementasi Dekolonisasi Budaya dalam Pembangunan Perdamaian: Pelatihan Sere Bissu di Kabupaten Bone, Sulawesi Selatan
Get PDFGender diversity is not limited to essentialist gender paradigms based on binary gender identities. In fact, various gender identities embedded in indigenous beliefs and culture have emerged as a result of various social, cultural and political factors. One such example is the Bissu community among the Bugis peoples of South Sulawesi. Using an indigenous queer perspective on peacebuilding, this article challenges the dominant gender binary paradigm, promoting tolerance and inclusivity. This perspective contributes to the understanding of human rights at the global community level by emphasizing the importance of decolonization, intersectionality, and the recognition of diverse identities based on the experiences of each group. The implementation will be carried out through a model of peace building for indigenous queers through the Sere Bissu Training in collaboration with the Project Budaya Bone, Kerukunan Waria-Bissu Bone (KWRB), the Bone Regency Tourism Office, and the Bone Regency Cultural Office in 2022 in Bone Regency, South Sulawesi. Sere Bissu training has successfully ensured active participation of Bissu group, developed skills and resources within the community, and disseminated the importance of cultural identity and indigenous belief that can lead to Bissu community advocacy and reconciliation. This training has become a peacebuilding model for revitalizing and supporting the Bissu community.Artikel Pengabdian kepada Masyarakat ini memaparkan implementasi dekolonisasi sebagai strategi budaya untuk promosi toleransi dan inklusivitas bagi kelompok gender marginal di Indonesia. Keragaman gender tidak hanya terbatas pada paradigma gender esensialis yang betumpu pada identitas gender yang bersifat biner. Beberapa faktor sosial, budaya, dan politik justru melahirkan berbagai identitas gender yang menubuh pada kepercayaan dan budaya lokal. Salah satunya pada komunitas Bissu pada suku Bugis di Sulawesi Selatan. Dengan menggunakan perspektif indigenous queer dalam pembangunan perdamaian, artikel ini menantang paradigma dominan terhadap pandangan gender biner, serta mempromosikan toleransi dan inklusivitas. Adapun perspektif ini menekankan pentingnya dekolonisasi, interseksionalitas, dan pengakuan atas beragam identitas berdasarkan pengalaman tiap kelompok sebagai kontribusi terhadap pemahaman hak asasi manusia pada tataran masyarakat global. Implementasi dilakukan lewat model pembangunan perdamaian bagi indigenous queer lewat Pelatihan Sere Bissu yang bekerjasama dengan Project Budaya Bone, Kerukunan Waria-Bissu Bone (KWRB), Dinas Pariwisata Kabupaten Bone, dan Dinas Kebudayaan Kabupaten Bone pada tahun 2022 di Kabupaten Bone, Sulawesi Selatan. Kesimpulannya, pelatihan Sere Bissu telah berhasil memastikan partisipasi aktif dari kelompok Bissu, pengembangan ketrampilan dan sumber daya dalam komunitas, serta mendiseminasikan pentingnya identitas dan tradisi budaya yang dapat mengarah ke advokasi komunitas Bissu hingga pada rekonsiliasi. Dengan kata lain, pelatihan Sere Bissu telah menempati model pembangunan perdamaian bagi komunitas Bissu pada tahap revitalisasi dan dukungan
