The Piper Betle Linn, is a plant that originates from the tropical regions of Central and South America. Betel plants are known for their anti-inflammatory, antioxidant, and antibacterial properties, as well as their potential to treat a variety of health conditions, including stomach aches, digestive disorders, and respiratory infections. From the content contained in betel leaves that can be used as a bathroom cleaner is phenol. Phenols in betel leaves are kavikol and kavibetol, which have antiseptic, antioxidant, and fungicidal power with antibacterial activity six times more effective than ordinary fluoride and phenol compounds. Betel leaves contain 4.2% essential oil and most of its components consist of betephenol which acts as an antibacterial agent besides that betel leaves contain antiseptic substances that can kill germs. The purpose of our research is to find out how the piper clean manufacturing process is and to find out the piper clean quality test. From the results of organoleptic tests conducted on 36 respondents, the Piper Clean that is most preferred by respondents is piper clean on the A20B10 variable with betel leaf extract: vinegar ratio of 200 ml: 100 ml. which has the characteristics of brown color, distinctive aroma of betel leaves and is very much liked by respondents. In addition to the organoleptic test, the results of our study were tested at LPPT UGM Yogyakarta with the results that piper clean has a pH of 3.15 with a temperature of 250 C, detergent equivalent of Sodium Dodecyl Sulfate 1492.25. it can be concluded that piper clean is safe to use and effective for floor cleaners

We address the problem of configuring a power distribution network with reliability and resilience objectives by satisfying the demands of the consumers and saturating each production source as little as possible. We consider power distribution networks containing source nodes producing electricity, nodes representing electricity consumers and switches between them. Configuring this network consists in deciding the orientation of the links between the nodes of the network. The electric flow is a direct consequence of the chosen configuration and can be computed in polynomial time. It is valid if it satisfies the demand of each consumer and capacity constraints on the network. In such a case, we study the problem of determining a feasible solution that balances the loads of the sources, that is their production rates. We use three metrics to measure the quality of a solution: minimizing the maximum load, maximizing the minimum load and minimizing the difference of the maximum and the minimum loads. This defines optimization problems called respectively min-M, max-m and min-R. In the case where the graph of the network is a tree, it is known that the problem of building a valid configuration is polynomial. We show the three optimization variants have distinct properties regarding the theoretical complexity and the approximability. Particularly, we show that min-M is polynomial, that max-m is NP-Hard but belongs to the class FPTAS and that min-R is NP-Hard, cannot 1 be approximated to within any exponential relative ratio but, for any $\epsilon$ > 0, there exists an algorithm for which the value of the returned solution equals the value of an optimal solution shifted by at most $\epsilon$.

This research is a classroom action research that aims to improve student learning outcomes in the Coordination System material through the application of the Teams Games Tournament learning model. The research subjects were 34 students of class XI-IPA 1 at SMAN 1 Manyaran for the 2021/2022 academic year. The research was carried out in 2 cycles and the collected data were analyzed using comparative descriptive analysis. The results showed that the application of the Teams Games Tournament cooperative learning model could improve the learning outcomes of the Coordination System in class XI-IPA 1 SMAN 1 Manyaran. This increase was shown by the results of the research from cycle 1 to cycle 2, namely 1) the average acquisition of the posttest results of cycle 1 was 74.41 and increased to 82.94 in the second cycle. 2). The number of students who completed in cycle 1 was 25 out of 34 students with an achievement percentage value of 73.53%, while in cycle 2, the number of children who completed increased to 28 out of 34 students with an achievement percentage value of 82.35%. ABSTRAKPenelitian ini merupakan penelitian tindakan kelas yang bertujuan untuk meningkatkan hasil belajar siswa pada materi Sistem Koordinasi melalui penerapan model pembelajaran Teams Games Tournament. Subyek penelitian adalah 34 orang siswa kelas XI-IPA 1 SMAN 1 Manyaran Tahun Pelajaran 2021/2022. Penelitian dilaksanakan dalam 2 siklus dan data yang terkumpul dianalisis dengan menggunakan analisis deskriptif komparatif . Hasil penelitian menunjukkan bahwa penerapan model pembelajaran kooperatif Teams Games Tournament dapat meningkatkan hasil belajar Sistem Koordinasi pada siswa kelas XI-IPA 1 SMAN 1 Manyaran. Peningkatan tersebut ditunjukkan oleh hasil penelitian dari siklus 1 ke siklus 2 yaitu 1) perolehan rata-rata hasil posttest siklus 1 sebesar 74,41 dan meningkat menjadi 82,94 di siklus kedua. 2). Jumlah siswa yang tuntas pada siklus 1 adalah 25 dari 34 anak dengan nilai prosentase ketercapaian sebesar 73,53%, sedangkan pada siklus 2, jumlah anak yang tuntas bertambah menjadi 28 dari 34 siswa dengan nilai prosentase ketercapaian sebesar 82,35%.

Penelitian ini bertujuan untuk mengetahui apakah konseling individu dengan manajemen diri dapat mengatasi perilaku membolos siswa SMA Negeri 1 Suralaga. Subjek dalam penelitian ini adalah siswa kelas X, XI dan XII SMA Negeri 1 Suralaga yang menunjukkan perilaku membolos yang berjumlah 6 (enam) orang. Penelitian ini merupakan penelitian tindakan bimbingan konseling (PTBK). Pengumpulan data yang dibutuhkan berupa pedoman observasi dan wawancara sebagai data pendukung dan angket (inventarisasi) digunakan sebagai alat pengumpulan data primer. Rancangan penelitian yang digunakan adalah pre test dan post test group, dalam rancangan penelitian ini dilakukan 2 kali observasi (pengukuran) yaitu sebelum dan sesudah treatmen. (01) dan (02) perbedaan antara 01 dan 02 diasumsikan sebagai efek dari pengobat. Kegiatan layanan konseling yang dilakukan dalam enam pertemuan untuk setiap klien dengan draft treatmen akan dilakukan dalam empat tahap yaitu penetapan tujuan penilaian - teknik implementasi - evaluasi dan terminasi. Hasil penelitian menunjukkan bahwa terdapat perubahan positif dari penurunan yang signifikan pada perilaku membolos siswa setelah mendapatkan pelayanan konseling individu dengan pendekatan perilaku teknik manajemen diri, dengan rincian: perilaku membolos sebelum diberikan traktir menunjukkan persentase rata-rata 76% termasuk dalam kategori tinggi. Setelah dirawat persentase rata-rata 43,5% termasuk dalam kategori rendah.

A new protocol for the identification of two sibling species of voles Microtus arvalis and M. rossiaemeridionalis was proposed by electrophoresis of blood proteins in polyacrylamide gel (PAGE). Animals captured in ten districts of Moscow, Kaluga, and Samara oblasts and Moscow natural territories (1030 individuals), as well as those taken from vivarium collections (five hybrids of the two species), were studied. A comparison of electrophoresis in PAGE, agarose gel, and cellulose acetate plates was carried out. The use of different organs and tissues for species identification was assessed. The relative electrophoretic mobility and the mass of a species-specific blood protein of the southern vole were determined.

The article presents the results of the study of the artistic image of the athlete in the Russian cinema of the XX-XXI centuries. According to the author, it is possible to distinguish “epoch-making images” of the heroes of athletes in different historical periods. The analysis of images of athletes leads to conclusion that despite the revealed distinctive features of these images, all of them were glorified and were used to internalize certain values, which in turn testifies to educational and value-forming functions of the domestic sport films focused on transmitting of socially approved patterns of behavior.

Статья посвящена гуманитарным аспектам текстуальности путешествия. Авторы полагают, что конструирование любого туристического опыта связано с особой ценностной, символической реальностью, таки образом «язык» путешествия обуславливается определённым культурным кодом, некоторые вариации которого представлены в данной работе.
