Abstract

Budaya merupakan hal yang selalu kita jumpai dalam lingkungan dan juga tidak terlepas dari ilmu kimia. Pengenalan budaya di daerahnya bagi generasi muda pada saat ini cukup sedikit yang diakibatkan oleh arus globalisasi yang berkembang pesat. Pengenalan budaya melalui pendidikan sains sangatlah menarik untuk dipahami. Persaingan pada abad ke- 21 sangat dibutuhkan kemampuan komprehensif, kreatif, literasi tinggi dan kemampuan memecahkan masalah. Penelitian ini merupakan studi pustaka dengan 23 jurnal yang ditemukan memenuhi kriteria inklusif yang telah ditentukan sebagai berikut: 1) jurnal 5 tahun terakhir (2019-2023); 2) jurnal terakreditasi SINTA dan Scopus 3) ruang lingkup penelitian di Indonesia dan Luar Negeri 4) kata kunci jurnal etnosains, etnokimia, laju reaksi. Pencarian jurnal menggunakan aplikasi Publish of Perish 8. Literatur sains menjadi aspek yang diukur secara serius dengan pendekatan etnokimia yang mayoritas melibatkan peserta didik sekolah menengah. Etnokimia menunjukkan minimnya pembahasan dalam materi laju reaksi. Nabun merupakan etnokimia yang dibahas dalam faktor yang mempengaruhi laju reaksi yang merupakan tradisi budaya Betawi. Penyampaian isu ini akan memperluas informasi dan mengubah perilaku siswa dalam menjawab permasalahan yang luas. Hasil penelitian ini dapat dijadikan bahan kajian, aspek pengukuran yang masih minim dilakukan adalah berpikir kritis, keterampilan penjelasan ilmiah, dan melestarikan budaya dari pendekatan etnokimia. Pendekatan etnokimia atau etnosains adalah pendekatan yang menyajikan budaya yang ada disekitar atau pengetahuan budaya yang dimiliki oleh peserta didik yang dikaitan dengan konsep ilmu yang sedang dipelajari. Penelitian dalam 5 tahun terakhir secara keseluruhan telah dilakukan aspek pengukuran literasi sains dan masih minim dalam pengukuran aspek berpikir kritis, keterampilan penjelasan ilmiah, dan melestarikan budaya

Abstract

General elections (Pemilu) are a strong foundation of democracy, but are often affected by various manipulative tactics used by political actors. This article aims to present a literature review of manipulative tactics that often appear in the context of general elections. We analyze various empirical and theoretical studies that highlight manipulative practices such as duping the masses, spreading fake news, money politics, voter intimidation, and gerrymandering. Through a synthesis of the literature, we identify the factors that drive the use of manipulative tactics and their impact on democratic integrity. Additionally, we explore efforts to address manipulative tactics, including stricter regulations, voter education, and the role of media and civil society in combating practices that undermine democratic processes. This analysis provides a deeper understanding of political dynamics in general elections and their relevance in the context of sustainable democratic development.

Abstract

This study aims to observe the dynamics of Vibrio sp. abundance in the culture media and hepatopancreas organs of vaname shrimp (Litopenaeus vannamei). Samples were taken from three pond plots (D7, D8, and D11). Bacterial isolation was carried out using TCBS agar media, both from pond water and shrimp hepatopancreas organs. The results showed that the abundance of Vibrio sp. in the culture media fluctuated during the maintenance period, with a significant increase especially towards the end of maintenance. Meanwhile, Vibrio sp. was also found in hepatopancreas tissue, but its appearance did not always coincide with the spike in the water media. This variation indicates that bacterial infections do not only depend on environmental conditions, but are also influenced by shrimp immunity and pond management. Increased levels of organic matter thought to play a role in supporting the growth of pathogenic bacteria. This study shows the importance of monitoring water quality parameters and overall organ health to prevent bacterial infections. The abundance of Vibrio sp. in the culture media in three pond plots reached D7= 3.49 × 104, D8= 8.69 × 104 and D11= 4.60 × 104 CFU/ml, with the highest peak in plot D8 in the 5th week. In the Hepatopancreas, the abundance of Vibrio sp. reaching D7= 145.6 × 103, D8= 86 × 103 and D11= 103.1 × 103. In the 5th week, the three plots experienced stable values with two dilutions of plot D7= 7.03 × 103, plot D8= 48.9 × 103, and plot D11= 55.8 × 103. Penelitian ini bertujuan untuk mengamati dinamika kelimpahan Vibrio sp. pada media budidaya dan organ hepatopankreas udang vaname (Litopenaeus vannamei). Sampel diambil dari tiga petakan tambak (D7, D8, dan D11). Isolasi bakteri dilakukan menggunakan media TCBS agar, baik dari air tambak maupun organ hepatopankreas udang. Hasil penelitian menunjukkan bahwa kelimpahan Vibrio sp. di media budidaya mengalami fluktuasi selama masa pemeliharaan, dengan peningkatan signifikan terutama menjelang akhir pemeliharaan. Sementara itu, Vibrio sp. juga ditemukan pada jaringan hepatopankreas, namun kemunculannya tidak selalu bersamaan dengan lonjakan di media air. Variasi ini menunjukkan bahwa infeksi bakteri tidak hanya bergantung pada kondisi lingkungan, tetapi juga dipengaruhi oleh daya tahan tubuh udang dan pengelolaan tambak. Peningkatan kadar bahan organik diduga berperan dalam mendukung pertumbuhan bakteri patogen. Penelitian ini memperlihatkan pentingnya pemantauan parameter kualitas air dan kesehatan organ secara menyeluruh untuk mencegah infeksi bakteri. Kelimpahan Vibrio sp. pada media budidaya di tiga petak tambak mencapai D7= 3,49 × 104, D8= 8,69 × 104 dan D11= 4,60 × 104 CFU/ml, dengan puncak tertinggi pada petak D8 di minggu ke-5. Pada Hepatopankreas, kelimpahan Vibrio sp. mencapai D7= 145,6 × 103 , D8= 86 × 103 dan D11= 103,1 × 103. Pada minggu ke-5 ketiga petak mengalami nilai yang stabil dengan dua kali pengenceran petak D7= 7,03 × 103, petak D8= 48,9 × 103, dan petak D11= 55,8 ×× 103.

Model Student Teams Achievement Division (STAD) dipilih sebagai salah satu alternatif pembelajaran di mana guru dalam mengajar dapat membantu siswa untuk melatih kemampuan komunikasi matematika. Penelitian ini bertujuan untuk mendeskripsikan kemampuan komunikasi matematis siswa SMP ditinjau dari tingkat kecerdasan emosional dengan model pembelajaraan kooperatif tipe Kooperatif tipe Student Teams Achievement Division (STAD). Penelitian ini merupakan jenis penelitian deskriptif dengan pendekatan kualitatif. Instrumen utama dalam penelitian ini adalah peneliti dan instrumen pendukungnya adalah angket kecerdasan emosional, tes kemampuan komunikasi matematis, dan pedoman wawancara. Hasil penelitian ini menunjukkan bahwa kemampuan komunikasi matematis siswa yang memiliki kecerdasan emosional tinggi dengan menggunakan model pembelajaran kooperatif tipe Student Teams Achievement Division (STAD) hanya perlu membaca keseluruhan soal sekali untuk menemukan informasi yang terdapat pada soal kemudian mengulangnya kembali untuk menuliskannya pada lembar jawaban yang disediakan. Selain itu, subjek sangat santai dan yakin dalam mengungkapkan informasi secara lisan. Kemampuan komunikasi matematis siswa yang memiliki kecerdasan emosional sedang dengan menggunakan model pembelajaran kooperatif tipe Kooperatif tipe Student Teams Achievement Division (STAD)harus membaca permasalahan berulang-ulang terlebih dahulu untuk menemukan informasi yang terdapat pada soal, namun dapat menuliskannya dengan benar pada lembar jawaban yang disediakan. Kemampuan komunikasi matematis siswa yang memiliki kecerdasan emosional rendah dengan menggunakan model pembelajaran kooperatif tipe tipe Student Teams Achievement Division (STAD) harus disuruh terlebih dahulu untuk membaca dan harus dilihat oleh peneliti pada saat mengerjakan soal, karena jika tidak dilihat subjek hanya diam saja dan melamun, namun dapat menuliskannya dengan benar pada lembar jawaban yang disediakan. Selain itu subjek masih tersendat-sendat dan berpikir lama dalam mengungkapkannya secara lisan.

Abstract

The excise contribution from the Tobacco Products Industry (IHT) in 2020 amounted to Rp170.24 trillion or 96.56% of all Indonesian excise revenue. The Covid-19 pandemic caused tobacco exports in 2020 to decrease by 6.41% or 2,134 tons. Based on these conditions, it is necessary to research the competitiveness of tobacco exports during the Covid-19 pandemic in the main destination countries. The method of determining the location used is a purposive method, namely in Belgium, Singapore, Dominican Republic, Sri Lanka, Germany, the Netherlands, and the United States. The data used is time series data for 38 months starting from August 2018 to September 2021. The analysis methods used are IIT (Intra Industry Trade), RCA (Revealed Comparative Advantage), and EPD (Export Product Dynamic). The results showed a) IIT analysis, that most countries experienced a decline during the Covid-19 pandemic. Countries that experienced a decrease were the Netherlands, Dominican Republic, Singapore, and Sri Lanka, while those that experienced an increase were Belgium, Germany, and the United States. b) RCA analysis in the seven main destination countries showed a strong position. c) EPD analysis of most of the main destination countries for tobacco exports showed positive results, except for the United States which experienced a decrease.
