Abstract

Spatial modeling of landslide hazards in the Tarusan watershed is an effort to reduce losses due to landslide disasters. The purpose of this article is; determine the frequency ratio value of each parameter that causes landslides, and perform spatial modeling of landslide hazards using the frequency ratio method. The method used is a quantitative method with a modeling approach to determine the pixel value based on the frequency ratio. The results of the research show that the largest frequency value is found in the land cover parameter in the form of mixed gardens with an FR value of 2, 10, and rainfall with an FR value of 2.06. Thus, the triggering factors for landslides in the Tarusan watershed are changes in land cover and rainfall. The results of landslide hazard modeling in the Tarusan watershed show a high hazard area of ​​2095.41 ha or 7.39%, a medium hazard area of ​​4148.73 ha or 14.63%, and a low hazard area of ​​22117.46 ha or 77.98%. Key words: hazard, landslide, spatial model

Abstract

Penelitian ini dilakukan karena aktivitas belajar siswa belum optimal sehingga siswa terlihat kurang antusias dalam mengikuti kegiatan pembelajaran. Selain itu, alokasi waktu yang dibutuhkan guru masih kurang sehingga mengakibatkan transfer pengetahuan kepada siswa tidak optimal. Penelitian ini bertujuan untuk mengetahui pengaruh learning cycle 5E terhadap aktivitas belajar pendidikan agama islam siswa kelas XI IPS di SMA Negeri 4 Kota Bukittinggi. Pendekatan yang digunakan dalam penelitian ini adalah quasi experiment. Populasi penelitian ini adalah semua siswa kelas XI di SMA Negeri 4 Kota Bukittinggi dan sample di ambil dari 2 kelas XI yaitunya XI IPS 2 dan XI Ips 3. Pengumpulan data dengan menggunakan observasi angket. Data dianalisis dengan menggunakan analisis deskriptif dan uji t untuk pengujian hipotesis. Hasil penelitian menunjukan rata-rata posttest kelompok eksperimen adalah 81,14 dan rata-rata posttest kelompok kontrol adalah 69,23. Hasil analisis dengan menggunakan Independent Sample T-test antara kelompok eksperimen dan kelompok kontrol diperoleh nilai t-hitung sebesar 89,779 dan nilai t-tabel sebesar 2,750, serta taraf signifikansi sebesar 0.000. Jadi, dapat disimpulkan bahwa aktivitas belajar siswa yang belajar menggunakan model pembelajaran learning cycle 5E berpengaruh aktif dan lebih baik daripada aktivitas belajar siswa yang belajar menggunakan model pembelajaran konvensional di kelas XI di SMA Negeri 4 Kota Bukittinggi.

Abstract

ABSTRACTCoffee is a type of plantation plant that has been cultivated for a long time and has a fairly high economic value. This study aims to determine the effect of soaking time on caffeine levels in Robusta and Arabica coffee beans using the maceration method. The coffee beans were ground, then the powder was sieved and extracted using 70% alcohol using the 3, 5 and 7 day maceration immersion method. The extract obtained was extracted with chloroform and determined using UV-Vis Spectrophotometry. The results showed that the caffeine content of Robusta coffee for 3, 5 and 7 days was 4.82±0.04; 5.59±0.04 and 6.55±0.06. Arabica type caffeine content obtained 3.83±0.02; 5.04±0.02; and 6.45±0.03. It was concluded that there were differences in the levels of caffeine contained in Robusta and Arabica coffee beans by varying the duration of immersion for 3 days, 5 days, 7 days, but for both Robusta and Arabica coffee types, there was no difference in the extracted caffeine content. Keywords: Caffeine, Robusta, Arabica, Spectrophotometry UV-Vis  ABSTRAKKopi merupakan salah satu jenis tanaman perkebunan yang sudah lama dibudidayakan dan memiliki nilai ekonomis yang cukup tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh lama perendaman terhadap kadar kafein dalam biji kopi Robusta dan Arabika dengan menggunakan metode maserasi. Biji kopi dihaluskan kemudian serbuk diayak dan diesktraksi menggunakan alkohol 70 % dengan menggunakan metode maserasi perendaman 3, 5 dan 7 hari. Ekstrak didapat diekstraksi dengan dengan kloroform dan ditetapkan kadarnya menggunakan Spektrofotometri UV-Vis. Hasil penelitian menunjukkan kadar kafein kopi jenis Robusta untuk 3, 5 dan 7 hari diperoleh 4,82±0,04; 5,59±0,04 dan 6,55±0,06. kadar kafein jenis Arabika diperoleh 3,83±0,02; 5,04±0,02; dan 6,45±0,03. Disimpulkan bahwa adanya perbedaan kadar kafein yang terkandung pada biji kopi robusta dan arabica dengan divariasikan lamanya perendaman 3 hari, 5 hari, 7 hari, tetapi untuk jenis kopi baik Robusta dan Arabika tidak terdapat perbedaan kadar kafein yang terekstraksi. Kata kunci: Kafein, Robusta, Arabica, Spektrofotometri UV-Vis

Abstract

One of Aceh's qanuns that regulates the method of election and conditions of geuchik is Aceh Qanun No. 4 of 2009 on the Procedures for the Election and Dismissal of Keuchik in Aceh. This research highlights the criteria for a proper village head/Keuchik in accordance with the legal provisions of the qanun. This study aims to describe the understanding of the community and the Keuchik Election Committee (P2K) of the provisions of the nomination of village heads and the implementation of the determination of candidates for village heads in Pulo Reudeup Village, Kuta Blang District, Bireuen Regency. The research method uses a qualitative approach through interviews and documentation. The results showed that the community's understanding of the nomination requirements was good, but the election mechanism was still poorly understood. The implementation of the determination of village head candidates needs to be improved to be in accordance with the applicable qanun.

Abstract

This article explores the role of Bayt Al-Hikmah as a monumental intellectual center during the Abbasid Dynasty. Built during the time of Caliph Abu Ja'far al-Mansur, this center developed into a famous library during the reign of Harun al-Rashid and Al-Ma'mun. It functions not only as a library, but also as an educational institution, astronomical observatory, and translation center, housing a collection of more than 60,000 books from various languages and regions. Important factors influencing the development of Bayt Al-Hikmah included the caliph's love of science, extensive translation activities, use of paper, the presence of scientists from various regions, material support, and enthusiasm for studying Islamic teachings. Despite achieving glory, the summary of the Abbasid dynasty started from internal political conflict to the Mongol attack which resulted in the fall of the city of Baghdad and the destruction of Bayt Al-Hikmah. Even though this intellectual center collapsed, the scientific legacy it produced remains a testament to the glory of science at that time, even though it experienced a tragic end.
