Abstract

The population growth rate of Alor district continues to increase every year. To estimate the population for the following year, population estimates are usually used, which are used as the basis for economic and social planning to determine future needs. Population growth models with exponential and logistic models are well known in determining population growth. The research method used is a case study of the population in Alor Regency. The data in this study is population data obtained from the Central Statistics Agency (BPS) Alor from 2015-2019. The data that has been obtained is processed using Exponential and Logistics methods to obtain forecast data or projections of the population of Alor Regency in 2020 Alor. Based on the results of the discussion above, exponential and logistic models can be used to predict the population of Aor Regency in 2030. Based on the results of the above discussion, exponential and logistical models can be used to predict the number of Human Development Index of Alor Regency in 2030. Predicted number of Human Development Index of Alor Regency in 2030, based on the results of exponential model 1 is 64.12; exponential model 2 is 65.69; and the exponential model 3 is 65.72. Meanwhile, the prediction of the Human Development Index for Alor Regency in 2030 based on the logistics model is 64.98.

Abstract

Research through community service (CS) in Bunga Bali village, Pantar Timur sub-district, Alor. PKM instilling the basic concepts of addition and subtraction of fractions in 3rd grade students of SD GMIT Abangiwang is carried out with the aim of finding out the extent of students' knowledge of fractions, whether the denominator is the same or the denominator is different. This PKM activity offers planting the basic concept of multiplication as a reference in understanding fractions. In this PKM, it was found that there was an increase in students' understanding of mathematics, especially fractions in simple fractions, while in fractions whose denominators were not the same, it was necessary to emphasize to students to study harder. The average test result is 61.54% in the sufficient category. Factors causing difficulties in solving simple fractions based on the results of interviews with third grade homeroom teachers generally include interest and motivation, teacher factors, environmental factors, teacher factors, infrastructure factors, environmental factors, and the need for discipline during teaching and learning activities. Some of the 3rd grade students of SD GMIT Abangiwang still find it difficult to memorize multiplications from 1 to 10. This makes it difficult for students. This makes it difficult for them in the section on equating 'fractions with different denominators'. The researcher offers teachers in the field of study that they need to strengthen the basics of multiplication before discussing fractions material.

Abstract

Perkawinan merupakan anugerah Tuhan yang mestinya dihargai. Proses perkawinan merupakan interaksi biologis dimana interaksi tersebut mestinya berdampak positif dan tidak terkesan membebani keluarga. Perempuan yang pernah kawin di bawah umur (< 17 tahun) baik interaksinya berjalan sesuai kaidah yang berlaku dan atau pun kawin yang tidak menjurus kepada berumah tangga, sangatlah berdampak secara negatif dalam komunitas. Dampak yang akan dirasakan ketika perempuan kawin di bawah umur yaitu morak-mariknya rumah tangga yang akan dibina, masih ada ketergantungan yang sebagian besar mengharapkan keluarga, tingkat kekerasan dalam rumah tangga yang terus meningkat. Jumlah populasi perempuan pernah kawin di bawah umur atau kawin dibawah umur 17 tahun di provinsi Nusa Tenggara Timur (NTT) dari tahun 2016 sampai 2020 adalah: tahun 2016 sebanyak 5,55%, tahun 2017 sebanyak 6,67%, tahun 2018 sebanyak 5,06 %, tahun 2019 sebanyak 5,11%, dan tahun 2020 sebanyak 5,28% dan rata-rata jumlah populasi yang kawin dibawah umur (umur kurang dari 17 tahun) dari tahun 2016 sampai tahun 2020 sebanyak 5,53%. Proyeksi pada tahun 2026 jumlah populasi perempuan pernah kawin di bawah umur (umur kurang dari 17 tahun) di provinsi Nusa Tenggara Timur (NTT), berdasarkan rumus model eksponensial , ketika t=10, maka Hal ini, berdasarkan model perhitungan model eksponensial mengalami peningkatan sebanyak . Hal ini akan berdampak pada lintas bidang yaitu meledaknya jumlah penduduk, kemiskinan, terganggunya stabilitas ekonomi, rendahnya tingkat pendidikkan, stabilitas keamanan dalam hal kekerasan dalam rumah tangga, kasus perselingkuhan dan lain-lainnya yang berdampak secara negatif. Hal ini akan berdampak pada lintas bidang yaitu meledaknya jumlah penduduk, kemiskinan, terganggunya stabilitas ekonomi, rendahnya tingkat pendidikkan, stabilitas keamanan dalam hal kekerasan dalam rumah tangga, kasus perselingkuhan dan lain-lainnya yang berdampak secara negatif. Perlu dilakukan sosialisasi atau pun strategi untuk dapat membatasi kondisi dimaksud, dalam hal ini mengurangi atau membatasi persentasi jumlah perempuan kawin di bawah umur 17 tahun.

Abstract

The income of traditional fishermen in Bungabali village, Pantar Timur sub-district, based on research data, will be used to project the income of traditional fishermen using the exponential model. When the researcher analyzes the data, the researcher will compare the data of several years that already exist with the projected data. From the comparison results, it turns out that the projected data is close to the actual data. Therefore, the projection is close to the actual data, so the exponential model can be used to project the income of traditional fishermen in 2022 to March 2023. Researchers project the income of traditional fishermen in Bungabali village, Pantar Timur sub-district every month, starting from January 2022 until the month of January 2022. March 2023. After that, researchers will clearly get the results of the projected income of fishermen in Bungabali village, Pantar Timur sub-district, precisely in March 2023. Projected average amount of income (not deducted by operating costs) or gross income for traditional fishermen in Bungabalik village, Pantar district East Alor district in March 2023 as much as 1473,302 thousand rupiah or Rp. 1,473,302 or approximately Rp. 1,473,000. This income analysis has not yet calculated expenses or operational costs. The fishermen are very dependent on the results of fishing. The economic condition of the household is still concerning, which will have an impact on many conditions, including the level of education of the fishermen's children. The results of interviews by researchers with fishermen stated that on average it was difficult for fishermen to take care of their children to the level of education due to unstable income.

Abstract

Some simple polynomial equations can be solved by the remainder theorem, so there is no need for numerical methods to solve them, because the roots of equations are very easy to do using analytical methods, while there are some polynomial equations that are difficult and complex to find roots using analytical methods. In this literature review, researchers will use the bisection method and the false rule to find the roots of polynomial equations. Based on the steps or sequence of calculation of the polynomial roots of , using the bisection method, the author states that from the first step to the eleventh step, if the calculation continues then in the second step f(a)*f(c)>0 or away from zero as shown in table 1 above. The author states that if the twelfth step continues, then f(a)*f(c) will approach zero and it can be seen that there are looping process approaches resulting from f(a)*f(c). This research study concludes that the roots of the polynomial of , using the bisection method are 1.36474675. Based on the steps or sequence of calculating the roots of the polynomial of on, using the false position method (false rule), the author states that from the first step to the 366th step it turns out that f(c)=0.003195 when c=1,365423447. Thus the polynomial roots of using the false position method (regulation false) are 1.365423447. Keywords: Roots of polynomial equations.
