Seleksi Nilai Fuzziness Exponent Optimal pada Algoritma Fuzzy c-Means untuk Mengelompokkan Provinsi di Indonesia Berdasarkan Indikator Pembangunan Ekonomi
No full textPada tahun 2015, PBB merancang 17 Tujuan Pembangunan Berkelanjutan (SDGs) untuk mencapai kesejahteraan manusia pada tahun 2030 dengan mengintegrasikan tiga dimensi pembangunan berkelanjutan: ekonomi, sosial, dan lingkungan. Salah satu faktor yang digunakan untuk menilai keberhasilan sebuah wilayah atau pemerintahan dalam mengelola kesejahteraan dan kemakmuran masyarakat adalah tingkat perekonomian. Untuk mewujudkan kondisi tersebut diperlukan strategi dalam pembangunan pada sektor ekonomi. Penelitian ini bertujuan untuk mengelompokkan Provinsi di Indonesia menjadi 3 klaster berdasarkan indikator pembangunan ekonomi menggunakan algoritma fuzzy c-means. Penentuan 3 klaster dimaksudkan untuk klaster provinsi dengan tingkat pembangunan ekonomi rendah, sedang dan tinggi. Data yang digunakan dalam penelitian ini merupakan data sekunder yang diperoleh dari laman resmi Badan Pusat Statistika. Dengan mengetahui karakteristik provinsi berdasarkan indikator pembangunan ekonomi (IPE), maka pengambil keputusan dapat menyusun strategi perencanaan program pembangunan ekonomi berdasarkan skala prioritas pada masing-masing provinsi. Hasil pengelompokan menunjukkan bahwa Provinsi Papua sangat membutuhkan prioritas pembangunan khususnya dalam sektor ekonomi guna peningkatan indeks pembangunan manusia, angka partisipasi sekolah berusia 7 sampai 12 tahun, angka partisipasi sekolah berusia 13 sampai 15 tahun, angka partisipasi sekolah berusia 16 sampai 18 tahun, sumber air minum yang layak, sumber penerangan listrik, dan sanitasi yang layak, karena indikator-indikator tersebut memiliki nilai rendah

Generalization of Euler\u27s Inequality to Prove Planarity of Graphs K_5 and K_(3,3)
Abstract
The study of literature on graph theory, especially the planarity of a graph, which is to determine whether a graph is a planar graph or a non-planar graph, has been widely discussed. This article\u27s discussion is slightly different, namely generalizing the planarity theorem for and the planarity theorem for This generalization is important because it can prove the planarity of and and the planarity of several related graphs. Proving the unplanarity of complete graphs and provide significant benefits to developing graph planarity theory and strengthens the guarantee of truth in its application. The urgency of the proof has a significant role in determining the planarity of the related graphs, either isomorphic or subdivision. One of the products of its role is the birth of Kuratovski\u27s theorem, which provides the necessary and sufficient conditions for a planar graph. The generalization process is carried out by studying the special properties of and . These unique properties are generalized to obtain a valid property for and . Based on the results of the generalization of these properties, then combined with the Euler inequality theorem and the resulting theorem is if is a planar graph, connected, and the length of the shortest cycle is k, with then applies £ (n-2). The benefits of this generalization can be used to prove and directly and some related graphs quickly.
Penulisan artikel ini bertujuan untuk melakukan generalisasi atau perumuman teorema planaritas untuk K_5 dan teorema planaritas untuk K_3,3. Eksistensi perumuman teorema ini penting karena dapat membuktikan planaritas K_5 dan sekaligus K_3,3 serta planaritas beberapa graf yang terkait. Article ini merupakan hasil kajian literatur tentang teori graf, khususnya planaritas suatu graf, yaitu menentukan apakah suatu graf itu termasuk graf planar atau graf tidak planar. Pembuktian ketidakplanaran graf lengkap K_5 dan K_3,3 memberikan manfaat besar terhadap pengembangan teori planaritas graf dan memantapkan jaminan kebenaran pada terapannya. Urgensi pembuktiannya memiliki peran yang besar dalam menentukan planaritas graf-graf yang terkait, baik isomorfik atau subdivisi. Salahsatu produk perannya adalah lahirnya teorema Kuratovski yang memberikan syarat perlu dan cukup suatu graf planar. Teorema Kurotavski menjelaskan bahwa suatu graf G adalah planar jika dan hanya jika G tidak memuat subgraph yang isomorfik dengan K5 atau K3,3 atau sebarang graf subdivisi dari K5 atau K3,3. Proses generalisasi teorema dilakukan melalui kajian terhadap sifat-sifat khusus pada K_5 dan sifat-sifat khusus yang dimiliki K_3,3. Sifat-sifat khusus tersebut diperumum sehingga diperoleh suatu sifat yang berlaku baik untuk K_5 dan K_3,3. Berdasarkan hasil generalisasi sifat tersebut, kemudian dikombinasikan pada teorema pertidaksamaan Euler dan dihasilkan teorema yaitu jika G suatu graf planar, terhubung, |V(G)|=n, |E(G)|=m dan panjang sikel terpendeknya adalah k, dengan k3 maka berlaku . Teorema generalisasi ini mampu membuktikan K_5 dan K_3,3 secara langsung dan beberapa graf terkait secara mudah

Circuit bodyweight training: does it affect increasing arm muscle endurance and archery accuracy in pandemic conditions?
No full textRestrictions on community activities due to the spread of the Covid-19 virus have changed sports in Indonesia, forcing athletes to practice independently in their respective homes with training programs created by coaches. This study aims to find out the effect of circuit body weight training on arm muscle endurance and archery accuracy of archery athletes. This research is an experimental method of one group pretest-posttest design. This study employed purposive sampling with the criteria of elite archery athletes, still in high school, male, and willing to participate. Total of 12 athletes was given treatment with 8 movements for 16 meetings. The instrument is a holding bow digit test for arm muscle endurance, while archery accuracy uses 50 meters of archery. The collected data were examined for normality and homogeneity, then followed with t-test with the result that t count = 0.00 less than t (0.05). Based on the results, it is concluded that circuit bodyweight training positively improves arm muscle endurance and accuracy of archery athletes. Therefore, giving circuit bodyweight training can be used as a recommendation for physical exercise to increase arm muscle endurance and archery accuracy in archery athletes
Math self-regulated learning assisted by metacognitive support by reviewing sex differences in mathematics anxiety
No full textThe study aims to analyze the effect of mathematics self-regulated learning (MSRL) assisted by metacognitive support (MS) by reviewing sex differences (SD) in mathematics anxiety (MA). The reason is that MA causes students to have difficulty in learning, so good strategies and approaches are needed. In several studies, there is a relevant relationship between MA, SRL, and MS. This research is quantitative research using Spearman Rho analysis and ordinal regression analysis, with the research population being 3rd-grade students of primary schools in Sidoarjo, East Java. The instruments used in data collection were questionnaires and tests declared valid and reliable. The validity and reliability of the instrument were obtained through content validity assessment and item analysis testing. The results showed a relationship between SRL and MS to MA. There was a positive effect of MS-assisted MSRL in terms of SD on MA. Furthermore, the average student had a positive MS and a high MSRL. The highest MA students are at the moderate level, with a percentage of 79%, and are dominant in the affective aspect. However, when viewed from the SD, the MA showed that female students were more anxious than male students. Thus, the MS-assisted SRL has a good influence when viewed from SD to MA. The recommendation from this research is so that MS and SRL strategies can be implemented optimally. Teachers must prepare and explore the implementation of using the strategies and approach more deeply
School readiness analysis to implement an inclusive education policy: A case study at elementary school
No full textThis study aims to describe the readiness of elementary schools in one of the sub-districts in Padang City, which includes personnel/teachers, facilities, and infrastructure, and a developmental assessment format for children with unique/inclusive needs. This research uses a descriptive quantitative method. The research subject is the elementary school Principal, which was selected using a simple random sampling technique. The research instrument used was in the form of questions packaged in a Google Form using the Guttman scale. Data were analyzed using descriptive statistics. The results showed that all schools responded well to the call for inclusive education in schools. However, the readiness of human resources, facilities, infrastructure, and several assessment systems are mostly not owned and not yet in schools. It shows that the enthusiasm for implementing inclusive education is practically not ready to be implemented considering the lack of availability of supporting facilities, both in terms of human resources and other supports
Students multicultural awareness of Aceh dormitory in Yogyakarta
No full textSeveral provinces in Indonesia have regional dormitories in Yogyakarta. This allows each student from various regions to have awareness of their respective ethnic identities, even though this has the potential to create horizontal conflicts. This study aims to describe how Aceh dormitory students in the city of Yogyakarta interpret ethnic identity and how intercultural communication relationships with other ethnicities and the surrounding community and how their views are related to the disintegration of the nation. This research is qualitative research using data collection techniques through interviews. The results showed that Acehnese students were aware of the ethnic identity that was the basis of the hostel and they saw that ethnic identity was important. Aceh dormitory students also introduce culture in cultural events, through which intercultural communication with other ethnicities and the surrounding community can be established. They think that as sons and daughters of the region, they should be proud of their respective ethnicities, but still have to uphold an attitude of inter-ethnic tolerance, so that this awareness does not cause the nation\u27s disintegration
Social construction of law enforcement for sexual violence against women in Aceh Utara
No full textThe level and types of sexual violence crimes in Indonesia are increasing and worrying the public. Law enforcement efforts to overcome criminal acts of sexual violence are increasingly being implemented. This study aims to examine the social construction of law enforcement against the crime of sexual violence against women in Aceh Utara. Respondents in the study amounted to 21 people who were selected with accidental sampling. The types of data in the form of primary data and secondary data were analyzed descriptively qualitatively. The results of the study explain that the legal basis used in the law enforcement process of sexual violence against women in Aceh Utara is Aceh Qanun Number 6 of 2014 concerning Inayat Law. Criminal charges for perpetrators of sexual violence in Aceh are whipping, fines, and imprisonment. It was found that the criminal sanctions contained in the qanun jinayat were lighter than the national law. For this reason, it is necessary to revise the qanun to provide a more severe deterrent effect on perpetrators, protect witnesses and victims with adopting developments in national laws related to sexual violence while still referring to the Aceh\u27s Islamic characteristics
