Malaria parasites, Plasmodium spp, can develop resistance to anti-malarial drugs. Hence, potential alternative therapeutic agents should be explored. This research aimed to investigate the anti-malarial effect of a combination of Carica papaya and Moringa oleifera leaf extract. Peter’s test performed on Balb/c mice to investigate the malarial parasite growth inhibition. Mice were infected with Plasmodium berghei by intraperitoneal injection to provoke rodent malaria. After infection, we grouped every 5-6 mice into different treatment groups, including a negative control group, a positive control group treated with artesunate, a moringa group, a papaya group, and a combination therapy group. Treatments were initiated 3 hours after infection (day 0) and continued every day until day 3. On day 4, we examined a thin smear of the tail vein blood for parasitemia to calculate the suppression rate. The result shows that the parasite suppression rate of C. papaya leaf extract (CPLE) is 15.02 % (percent parasitemia 4.56±1.96), the suppression rate of M. oleifera leaf extract (MOLE) is 17.32% (percent parasitemia 4.44±1.78) and that of the combination extract (CE) is 28.73% (percent parasitemia 3.82±1.48). In conclusion, there is a synergism of the anti-malarial effect of the combined leaf extract of C. papaya and M. oleifera.

Al-Qur'an as Godly words is believed to have beyond-humanistic literary values. In the Qur'an, there are words whose unusual arrangement with sentences that should have ended actually came first and vice versa. The wording in the Qur'an is arranged in such a way for a reason. An exegesis work by Wahbah al-Zuhaili, Tafsir Al-Munir, has tried to explain such aspects of the Qur'an, including the rules of taqdim and ta'khir, which significantly influences the Qur'an verses understanding. Focusing to explore the application of the rules as advised in Tafsir al-Munir, this literature study research will present several examples of interpretation in Tafsir al-Munir. Wahbah al-Zuhaili explains that among the purposes of taqdim and ta'khir in the Qur'an is to glorify, to prioritize, to specialize, and to show the superiority of something. Therefore, the rules have clearly great influence on the understanding of the Qur'anic verses.

Indonesia has imposed penalties for criminal acts of corruption by sentencing defendants to additional crimes, in addition to the main crime through court decisions. As a text, a court decision is also a practice that uses language like any other text. Therefore, it cannot be denied to analyze the text using the field of forensic linguistic studies. This research aims to explore the argumentative structure of court decisions regarding criminal acts of corruption and additional crimes as argumentative texts. In his analysis, all legal considerations become the basis for decision making. The data in this research is the text of the Jambi District Court decision no. 18/Pid.Sus-TPK/2023/PN Jmb using a qualitative descriptive method referring to a forensic linguistic approach. The results of this research include several things, namely the panel of judges used an indictment that had a high level of empathy and focalization because the indictment was obtained from interviews with the defendants. Thus, it can be concluded that because the claims of 'legitimate and convincing' and 'committing criminal acts of corruption together' are met argumentatively. However, the claim of 'subjected to criminal acts of corruption and additional crimes' needs to be questioned. This is because the six defendants had different sentences. In fact, in the indictment the detailed amount of money received is stated, so this claim is problematic from an argumentative theory perspective.

The multi-class imbalance problem has a higher level of complexity when compared to the binary class problem. The difficulty is due to the large number of classes that will present challenges related to overlapping between classes. Many approaches have been proposed to deal with these multi-class problems. One is a hybrid approach combining a data-level approach and an algorithm-level approach. This approach is done by the ensemble on the classifier and also oversampling on the minority class. SMOTE is an oversampling method that provides good performance, but this method is necessary to determine the best sample used in the interpolation process to generate new samples. The need for determining the best sample is related to the overlap between classes that always accompanies the multi-class imbalance problem. The existence of overlap requires efforts to determine the safe region to synthesize the sample in the oversampling process in SMOTE. The safe region is considered the best for synthesizing samples due to the lower tendency of overlapping. It can be done by constructing distance features to determine the safe region. The sample with the best distance and the lowest imbalance ratio will be selected as a sample in the over-sampling process with SMOTE. The main contribution of this research is the proposed method of Hybrid Approach with Distance Feature so that it can determine safe samples, with the main advantage being in addition to handling multi-class imbalances, it is also better for handling overlapping. The results of this study will be compared with Multiple Random Balance (MultiRandBal) which performs a random oversampling process. The results showed that the Augmented R-Value, Class Average Accuracy, Class Balance Accuracy, and Hamming Loss obtained in this method was better than the random oversampling process. These results also show that the Hybrid Approach with Distance Feature provides better results in handling multi-class imbalances when compared to MultiRandBal.

The study aimed at analyzing the effectiveness of assigning students to work in groups using Zoom breakout rooms to enhance their speaking self-efficacy to participate in active learning activities in an online learning context. Thirty-six students of Diploma 3 of the Accounting Program attending English for Accounting course were purposively selected as the respondents of the study. The data were collected using a three-part questionnaire distributed electronically using Google Forms. The validity and reliability of the questionnaire were measured using Pearson correlation and Cronbach Alpha. The students reported that their sources of English-speaking self-efficacy were enhanced as they had opportunities to develop both mastery and vicarious experience of English speaking, received social persuasion in the form of encouragement and motivation from one another, and experienced lower speaking anxiety. The teaching strategy enhanced the students’ English-speaking self-efficacy to participate in active learning activities to a moderate level. From being quiet and passive, they gradually transformed into active learners who could ask questions, chair discussions, answer questions, defend arguments, etc. It can be concluded that a group work in Zoom breakout rooms facilitated active learning activities as the students experienced opportunities to enhance English-speaking self-efficacy. There was a significant positive correlation between the use of group work in Zoom breakout rooms and students’ self-efficacy to participate in active learning activities. Implications and limitations of this current study are presented, and suggestions for further studies are offered.

Ketersediaan air tanah di Kelurahan Hargomulyo, Kapanewon Gedangsari, Kabupaten Gunung Kidul, D. I. Yogyakarta belum bisa mencukupi dengan banyaknya jumlah penduduk yang ada. Maka dari itu, dibutuhkan suatu studi pendugaan air tanah guna mendeteksi keberadaan lapisan air tanah (akuifer) di wilayah penelitian. Studi ini terlaksana pada tanggal 7 Agustus 2021 dengan titik ukur sebanyak 3 titik. Pendugaan kedalaman akuifer dalam studi ini memakai metode VES (Vertical Electrical Sounding) dengan menggunakan susunan elektroda Schlumberger. Metode VES adalah salah satu metode tahanan jenis yang bisa dimanfaatkan untuk pendugaan lapisan litologi bawah permukaan seperti lapisan akuifer. Pengambilan data lapangan VES dilakukan dengan memakai dua buah elektroda arus stainless steel dan elektroda potensial tembaga. Panjang bentangan pada tiap-tiap titik ukur, yaitu 400 meter. Data sounding tiap titik pengukuran diinterpretasi dengan memakai perangkat lunak HIRA, kemudian hasil interpretasi ditampilkan dalam bentuk log tahanan jenis dengan memperlihatkan nilai tahanan jenis, kedalaman, serta ketebalan tiap-tiap lapisan. Berdasarkan hasil pengolahan data diperoleh 10 hingga 12 lapisan batuan. Hasil analisis dari korelasi antar titik pengukuran dalam tiap lintasan memperlihatkan bahwa di daerah penelitian ada dua jenis akuifer, yaitu akuifer dangkal dan akuifer dalam. Akuifer dangkal ditemukan pada kedalaman 5-16 meter dengan nilai resistivitas berkisar antara 12,79 sampai 12,83 ohm.m, sedangkan akuifer dalam ditemukan pada kedalaman 22-85 meter dengan nilai resistivitas berkisar antara 10,56 sampai 16,85 ohm.m.

The dataset tends to have the possibility to experience imbalance as indicated by the presence of a class with a much larger number (majority) compared to other classes(minority). This condition results in the possibility of failing to obtain a minority class even though the accuracy obtained is high. In handling class imbalance, the problems of diversity and classifier performance must be considered. Hence, the Hybrid Approach method that combines the sampling method and classifier ensembles presents satisfactory results. The Hybrid Approach generally uses the oversampling method, which is prone to overfitting problems. The overfitting condition is indicated by high accuracy in the training data, but the testing data can show differences in accuracy. Therefore, in this study, Smoothed Bootstrap Resampling is the oversampling method used in the Hybrid Approach, which can prevent overfitting. However, it is not only the class imbalance that contributes to the decline in classifier performance. There are also overlapping issues that need to be considered. The approach that can be used to overcome overlapping is Feature Selection. Feature selection can reduce overlap by minimizing the overlap degree. This research combined the application of Feature Selection with Hybrid Approach Redefinition, which modifies the use of Smoothed Bootstrap Resampling in handling class imbalance in medical datasets. The preprocessing stage in the proposed method was carried out using Smoothed Bootstrap Resampling and Feature Selection. The Feature Selection method used is Feature Assessment by Sliding Thresholds (FAST). While the processing is done using Random Under Sampling and SMOTE. The overlapping measurement parameters use Augmented R-Value, and Classifier Performance uses the Balanced Error Rate, Precision, Recall, and F-Value parameters. The Balanced Error Rate states the combined error of the majority and minority classes in the 10-Fold Validation test, allowing each subset to become training data. The results showed that the proposed method provides better performance when compared to the comparison method

IntroductionWorking memory is critical in cognitive skills, especially among children. Children's ability to count and complete cognitive tasks are strongly associated with working memory abilities. Recent studies indicated that in addition to health factors, socioeconomic status also has a significant impact on children's working memory capacity. Despite these, evidence on the effects of socioeconomic status on working memory from developing countries yielded a somewhat puzzling picture.MethodsThis systematic review and meta-analysis provide a comprehensive summary of the recent evidence concerning the socioeconomic status determinants of children's working memory in developing countries. We searched via Cochrane library, ScienceDirect, Scopus, PubMed, and ProQuest. The initial search terms were [“socioeconomic”, “socio-economic”, “socioeconomic status”, “socio-economic status”, “income”, “poverty”, “disadvantaged”, “disparity”] AND [“working memory”, “short term memory”, “short-term memory”, “cognitive”, “achievement”, “performance”] AND [“child*”, “school child*”]. Odds ratio (for categorical outcome data) or standardized mean differences (for continuous data) and their 95% confidence intervals were calculated from the data generated.ResultsThis meta-analysis included five studies from 4 developing countries with a total of 4,551 subjects. Poverty was associated with a lower working memory score (OR: 3.12; 95% CI: 2.66, 3.65; p < 0.001). Another finding from 2 studies in this meta-analysis was that low mother education was associated with a lower score of working memory (OR: 3.26, 95% CI: 2.86, 3.71; p < 0.001).DiscussionPoverty and low level of mothers' education were significant risk factors for lowering working memory among children in developing countries.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, identifier: CRD42021270683.

Background and Objectives: Intestinal leakage commonly occurs in severe dengue infection with zonulin as a biomarker. The aim of this study was to determine the effects of NS1 on liver weight, zonulin expression and serum zonulin levels. Materials and Methods: This laboratory experiment used 18 ddY mice, which were randomly divided into control (C), PBS (T1), and PBS + NS1 (T2) groups. Mice in the T1 and T2 groups were intravenously injected with 500 µl PBS only and 50 µg NS1 respectively. Mice blood samples were collected before and after three-day treatment for measurement of zonulin level. The fresh liver was weighted directly and were then used for immunostaining. Results: The C group had lower wet liver weight compared to the T groups (p=0.001). Increased expression of liver zonulin was found in the T2 group, significant different from the C (p=0.014) and T1 groups (p=0.020). After treatment, serum zonulin levels in the T1 group was higher than that of the T1 group before treatment (p=0.035) but not in control (p=0.753) and T2 groups (p=0.869). Conclusion: Administration of 50 µg NS 1 increases wet liver weight and zonulin expression in hepatocytes, but did not increase serum zonulin levels in ddY mice.

Class Imbalance problems often occur in the classification process, the existence of these problems is characterized by the tendency of a class to have instances that are much larger than other classes. This problem certainly causes a tendency towards low accuracy in minority classes with smaller number of instances and also causes important information on minority classes not to be obtained. Various methods have been applied to overcome the problem of the imbalance class. One of them is the Hybrid Approach Redefinition method which is one of the Hybrid Ensembles methods. The tendency to pay attention to the performance classifier, has led to an understanding of the importance of selecting an instance that will be used as a classifier. In the classic Hybrid Approach Redefinition method classifier selection is done randomly using the Random Under Sampling approach, and it is interesting to study how performance is obtained if the sampling process is based on Cluster-Based by selecting existing instances. The purpose of this study is to apply the Hybrid Approach Redefinition method with Cluster-Based Instance Selection (CBIS) approach so that it can obtain a better performance classifier. The results showed that Hybrid Approach Redefinition with cluster-based instance selection gave better results on the number of classifiers, data diversity, and performance classifiers compared to classic Hybrid Approach Redefinition.

Lines and angles are essential for students because of geometry and its many applications in daily life. However, there are still many students who have difficulty grasping the material. Therefore, it is necessary to design learning using the right approach, context, and media. This study aims to produce a learning trajectory that can assist students in understanding the concept of lines and angles, maximize the effectiveness and efficiency of learning, create meaningful learning, and motivate student learning. This study used the Joglo Traditional House context as a starting point and the design research method developed by Gravemeijer and Cobb with three main steps: preparing for the experiment, designing the experiment (pilot experiment and teaching experiment), and retrospective analysis. However, in design experiment step is limited to the pilot experiment. In this study, all activities were designed based on Indonesian Realistic Mathematics Education. It involves six 7th-grade students from one of the junior high schools at Juwana Resident with three different abilities, namely two students for each level with high, moderate, and low ability. The learning trajectory generated in this study consists of a series of learning processes in four activities that can be used to develop local instructional theories and develop designs for further activities. Those are observing Joglo traditional house video for understanding lines and angles concepts, deducing line positions, discovering the angles' properties on parallel lines intersected by other lines, and solving lines and angles problems.

Weworuwet Hill, which is part of the Mbay hillside in Flores – NTT has sparse vegetation, only a stretch of grass that covers it, and is dry in the dry season like a barren teletabic hillside. This has the potential for surface water runoff, which has high destructive power, especially in the lowlands of Mbay City. To overcome this problem, a study to control the destructive force of water runoff was carried out by applying a water-trap series system, so that the potential for the destructive power of water can be reduced. Tertiary, secondary and primary runoff analysis studies are carried out to determine the location of the required water-traps. This study was conducted using a geographic information system-based program. Furthermore, the hydrological analysis of the area is carried out to determine which flood discharge can be controlled, and the volume of water that can be used for greening hills so that it can reduce the potential for damage to water runoff. The remaining water discharge in the downstream will be accommodated in the city pond, which functions as water conservation infrastructure. Finally, by applying a series of water traps on the tertiary, secondary and primary runoff from the Mbay hilly area, the destructive power of the runoff can be controlled, so that it does not impact and burden the residential plains of the town of Mbay.

Background: Annonaceous acetogenins have been reported to have anti-cancer properties but low viability. In this study, we aimed to investigate the potency of nanodiamonds to be employed as a carrier of annonacin to help increase its viability and inhibit the growth of breast cancer cells. Methods: The annonacin was coupled with nanodiamond and characterized using UV-Vis spectrophotometer, FTIR, SEM, and PSA, and determined their stability and drug release. A cell growth inhibition assay and cell migration assay was performed using the breast cancer MCF7 and T747D cell lines, and in vivo analysis was performed in rats (Rattus norvegicus). MCF7 and T747D cells were treated with 12.5 μg/mL annonacin coupled with nanodiamonds for 24 and 48 h and further analyzed by MTT, cell migration, and reactive oxygen species (ROS) assays. Twenty-five female rats were divided into five groups. Breast cancer was induced using two intraperitoneal doses of N-nitroso-N-methylurea (NMU) (50 and 30 mg/kg body weight). Annonacin coupled with nanodiamonds was administered by intraperitoneal injection (17.5 mg/kg body weight) for 5 weeks, one injection per 3 days. Results: Administration of annonacin coupled with nanodiamonds significantly reduced MCF7 cell growth and reactive oxygen species (ROS) levels. The in vivo study showed that administration of annonacin coupled with nanodiamonds significantly reduced PI3KCA levels and increased p53 expression, reduced cancer antigen-15-3 (CA-15-3) levels in serum, increased caspase-3 expression, reduced Ki-67 levels, and reduced the thickness of the mammary ductal epithelium. Conclusions: Collectively, this study demonstrated the effectiveness of nanodiamonds as a carrier of annonacin to inhibit breast cancer cell growth through inhibition of the PI3K/Akt signaling pathway.

Momentum is one of the physics topics that students can better understand with practical activities. The problem found in using the ticker timer as a speed gauge in the collision practicum is that the measurement process interferes with the system being measured. This research develops a collision practicum tool using a microcontroller and ultrasonic sensor as a distance recorder. The glide track used is an air track. Based on the research conducted, it can be concluded that the collision practicum tool with a microcontroller and a glide track in the form of an air track can work well.
