APPLICATION OF LEXICON BASED FOR SENTIMENT ANALYSIS OF COVID-19 BOOSTER VACCINATIONS ON TWITTER SOCIAL MEDIA USING NAÏVE BAYES METHOD

To combat the Covid-19 epidemic, the government issues laws governing vaccination implementation. Health Minister Number Ten of 2021 issued the regulation. This program raises advantages and disadvantages, necessitating examination through feedback. The opinions and narratives that individuals share on social media sites like Twitter can be used to get feedback. This work seeks to construct a model to assess public opinion of the Covid-19 Booster Vaccination by using the Lexicon Based technique to identify sentiment on tweet data. Naïve Bayes and logistic regression are the classification techniques employed in this study. The comparison of the two methods' findings reveals that Logistic Regression, with an accuracy of 72%, is superior to Naïve Bayes, which has an accuracy of 70%. There were 607 tweet messages from Twitter that were processed. From January 1 to July 30, 2022, the model was tested for its ability to interpret public opinion on Twitter. The model found that people's attitudes toward the COVID-19 booster shot tended to be favorable. It can be developed by including datasets for additional research. For further research, it can be developed by adding datasets

The effect of temperature and humidity on vo2max of PPLP athletes in Java, Indonesia

Efek dari lingkungan yang panas pada kinerja aerobik belum didokumentasikan dengan baik. Suhu dan kelembaban suatu lingkungan berpengaruh terhadap fisiologis tubuh dan dapat memengaruhi penampilan fisik, serta proses oxygen intake (VO2Max) yang kurang optimal. Hal ini menimbulkan sebuah pertanyaan apakah suhu lingkungan dapat berpengaruh terhadap kondisi tubuh pada saat berolahraga. Dengan demikian tujuan dari penelitian ini adalah untuk menguji efek suhu lingkungan yang berbeda terhadap VO2max pada atlet PPLP se-Pulau Jawa Indonesia. Penelitian ini menggunakan metode studi observasional, di manaeneliti hanya melakukan observasi pada satu saat, tanpa memberikan intervensi pada variabel yang akan diteliti. Subjek dalam penelitian ini terdiri dari 80 Atlet PPLP se-Pulau Jawa. Di antaranya yaitu; Jawa Tengah (20 Atlet), Jawa Timur (20 Atlet), Jawa Barat (20 Atlet) dan DIY Yogyakarta (20 Atlet). Hasil penelitian ini menunjukkan bahwa VO2max secara signifikan dapat berkurang pada suhu dan kelembaban 34°C/70% dan 32°C/60% dibandingkan dengan suhu dan kelembaban 23°C/69% dan 31°C/50%. Kinerja aerob sangat dipengaruhi oleh fungsi kardiovaskular. Lingkungan yang panas meningkatkan aliran darah kulit yang mengubah fungsi kardiovaskular. Sehingga hal ini dapat memengaruhi penurunan terhadap oxygen intake (VO2max).The effects of a hot environment on aerobic performance study have not been well documented. The temperature and humidity of an environment affect the body's physiology, influence physical appearance, and affect the less advantageous process of oxygen intake (VO2Max). Hence, a question arises in this study is the effect of environmental temperatures on the body condition while exercising. Accordingly, the purpose of this study is to examine the effect of different environmental temperatures on VO2max of PPLP (Students education and training center/pusat pendidikan dan latihan pelajar) athletes in java island, Indonesia. This study employs an observational study method, in which the researcher only observes at one time, without intervention on the examined variables. The subjects are 80 PPLP athletes from Java, specifically 20 Athletes of Central Java, 20 Athletes of East Java,20 Athletes of West Java and 20 Athletes of Yogyakarta. The results of this study indicate that VO2max is significantly decreased at the air temperature of 34°C with relative humidity of 70% and the air temperature of 32°C with relative humidity of60% compared to the air temperature of 23°C with relative humidity of 69% and the air temperature of 31°C with relative humidity of 50%. Aerobic performance is intensely influenced by cardiovascular function. A hot environment increases the blood flow of the skin, which changes cardiovascular function. Consequently, this decreases oxygen intake (VO2max)

Differences of physiological characteristics of taekwondo junior players vs pencak silat junior players

Introduction: Because of the fact that detailed data on the physiological characteristics of Pencak Silat are still limited. The primary purpose of this study to assess the physiological responses of Pencak Silat athletes and a secondary aim is to compare the physiological responses of Pencak Silat athletes with physiological responses of Taekwondo athletes. Material and Methods: This study has included 17 male junior martial art athletes (aged 15-16 years). This study requires all participants to completed one familiarization session and two experimental sessions. During the first session (laboratory condition), anthropometry was measured in the laboratory, and during the second session (on-court condition), the participants completed tests for anaerobic capacity (sprint test 60-m, vertical jump, push-ups, and sit-ups) and VO2max test. Results: The statistical analysis revealed no significant differences in anthropometry, vertical-jump, sit-ups, push-ups, and 60-m sprint results among TKD and PKS groups. Furthermore, the TKD group had significantly higher VO2max (p=0.015), when compared with the PKS group. Conclusion: The present investigation describes similar physiological characterizes, such as weight, height, BMI, BMR, body fat and also performances of vertical jump, situps, push-ups, and 60-m sprint tests among Taekwondo and Pencak Silat athletes. However, in comparison with junior Pencak Silat athletes, the junior Taekwondo athletes have better VO2max

A Chronicle of Indonesia’s Forest Management: A Long Step towards Environmental Sustainability and Community Welfare

Indonesia is the largest archipelagic country in the world, with 17,000 islands of varying sizes and elevations, from lowlands to very high mountains, stretching more than 5000 km eastward from Sabang in Aceh to Merauke in Papua. Although occupying only 1.3% of the world’s land area, Indonesia possesses the third-largest rainforest and the second-highest level of biodiversity, with very high species diversity and endemism. However, during the last two decades, Indonesia has been known as a country with a high level of deforestation, a producer of smoke from burning forests and land, and a producer of carbon emissions. The aim of this paper is to review the environmental history and the long process of Indonesian forest management towards achieving environmental sustainability and community welfare. To do this, we analyze the milestones of Indonesian forest management history, present and future challenges, and provide strategic recommendations toward a viable Sustainable Forest Management (SFM) system. Our review showed that the history of forestry management in Indonesia has evolved through a long process, especially related to contestation over the control of natural resources and supporting policies and regulations. During the process, many efforts have been applied to reduce the deforestation rate, such as a moratorium on permitting primary natural forest and peat land, land rehabilitation and soil conservation, environmental protection, and other significant regulations. Therefore, these efforts should be maintained and improved continuously in the future due to their significant positive impacts on a variety of forest areas toward the achievement of viable SFM. Finally, we conclude that the Indonesian government has struggled to formulate sustainable forest management policies that balance economic, ecological, and social needs, among others, through developing and implementing social forestry instruments, developing and implementing human resource capacity, increasing community literacy, strengthening forest governance by eliminating ambiguity and overlapping regulations, simplification of bureaucracy, revitalization of traditional wisdom, and fair law enforcement
