    Penelitian ini dilaksanakan di Jorong Pincuran Tujuah, Nagari Batipuh Baruah, Kecamatan Batipuh, Kabupaten Tanah Datar. Tujuan penelitian adalah (1) menganalisis risiko produksi yang terjadi pada kopi robusta di Jorong Pincuran Tujuah, (2) mendeskripsikan manajemen risiko yang dilakukan oleh petani pada produksi kopi robusta di Jorong Pincuran Tujuah. Penelitian ini menggunakan metode survei dengan analisis data deskriptif kualitatif dan analisis kualitatif. Hasil penelitian mengungkapkan bahwa sumber risiko produksi kopi robusta di Jorong Pincuran Tujuah yaitu hama monyet, hama musang, hama kelalawar, hama penggerek buah kopi, penyakit karat daun, penyakit bercak daun, kurang efektif dalam melakukan penyiangan, cuaca dan petani yang tidak melakukan sortasi. Berdasarkan analisis tingkat risiko produksi dengan menggunkan pemetaan risiko, risiko pada kuadran I merupakan tingkat risiko paling tinggi dengan frekuensi yang tinggi dan dampak yang juga tinggi bagi petani. Sumber risiko pada kuadran I yaitu hama penggerek buah kopi, kurang dalam penyiangan dan cuaca saat penjemuran. Strategi pengelolaan risiko yang dilakukan petani kopi Robusta di Jorong Pincuran Tujuah adalah stategi preventif dengan melakukan penyiangan dan berburu. Kata kunci: risiko produksi, sumber risiko, tingkat risiko, manajemen risiko.

    Sampah menjadi masalah yang sangat penting menjadi perhatian saat ini. Ketika jumlah sampah semakin hari semakin meningkat akan mengganggu kesehatan dan lingkungan. Untuk itu mengelola TPA Sampah menjadi objek wisata yang bernuansa edukatif sangat menarik untuk diteliti. Penelitian ini ingin mendeskripsikan kampanye Dinas Lingkungan Hidup dalam membangun TPA ( Tempat Pembuangan Akhir Sampah menjadi obyek wisata bernuansa edukatif.Metode penelitiannya menggunakan metode kualitatif. Teori yang digunakan S-O R. Hasilnya upaya kampanye yng dilakukan dinas lingkungan hidup sudah sangat baik dengan menjadikan wisata bernuansa edukatif seperti cara pengolahan sampah, membuaat pupuk dari bahan sampah (kompos) mengetahui gas methan dan melihat dari dekat cara belajar daur ulang dari bahan sampah.

    Telah dilakukan perancangan prototipe konveyor sistem pemisah barang berdasarkan tinggi dan massa yang menggunakan sensor ultrasonik dan sensor load cell. Perancangan konveyor dibuat sebagai pembawa dari barang yang akan dipisah. Konveyor terdiri dari motor DC yang dihubung pada driver L298N agar sabuk konveyor berputar dan motor servo-2 dan 3 sebagai pemisah barang. Pemisahan berdasarkan tinggi dan massa dari barang memanfaatkan teknologi Arduino Uno sebagai mikrokontroler, sensor ultrasonik, sensor load cell, modul HX711 dan LCD. Ketika barang di atas tempat penimbang dan di bawah sensor ultrasonik maka tinggi dan massa barang tampil pada layar LCD. Selanjutnya, motor servo-1 akan mendorong barang ke atas sabuk konveyor sehingga barang dapat dipisahkan oleh motor servo-2 dan 3. Hasil pengujian dengan barang menunjukkan motor servo-2 berputar 150o untuk barang yang dikategorikan kecil dengan tinggi ≤ 8 cm dan massa ≤ 45 g, sedangkan motor servo-3 berputar 150o untuk barang yang dikategorikan sedang dengan tinggi (9-12) cm dan massa dari (46-80) g. Apabila motor servo-2 dan 3 tidak bergerak maka barang akan dikategorikan besar dengan tinggi (13-20) cm dan massa (81-105) g.

    International audience; Hatchery managers and maintaining genetic diversity and fitness population in endangered and threatened species in pond is a important and difficult thing to do. But is must to do for conservation biology. Fitness and structure population depends on effective breeding number (Ne) and population connectivity between each other. The second most important thing is gene flow and genetic drift. Ne is major role in the maintenance of genetic diversity as indicator for inbreeding depresion and genetic drift. We sampled 6 hatchery in Jakarta and Bekasi Indonesia region and used 12 polymorphic microsatellite loci to quantify population genetic structure. Result in this study are, each farm have different methode. The old farmers is bapakGusi and bapakHasan (+30 years). Ne in bapakHasan and bapakGusi hatcheryis 66,667 and F value is 0,00749 and loosing allele (P) is 0,26183. Compared with younger farmers bapakYahya (5 years) have Ne = 133,333, F = 0,00375 and P = 0,06855. Even though hatchery bapakHasan and bapakGusi have the same value Ne, F and P but the result in population structure they are different founder populations. Hatchery bapakHasan have unique structure and alleles composition compared with other hatchery.; Manajemen hatchery penting untuk mempertahankan keragaman genetik dan kebugaran populasi dari spesies langka dan terancam punah di pembudidaya dan hal ini sulit dilakukan, tetapi menjadi keharusan untuk biologi konservasi. Kebugaran dan struktur populasi tergantung pada efektif breeding number (Ne) dan konektivitas populasi antara satu sama lain serta aliran gen dan pergeseran genetik. Ne memiliki peran utama dalam pemeliharaan keanekaragaman genetik dan sebagai indikator terjadinya inbreeding dan pergeseran genetik. Terdapat 6 hatchery sampel di wilayah Jakarta dan Bekasi Indonesia dengan menggunakan 12 lokus mikrosatelit polimorfik untuk mengukur struktur genetik populasi. Hasil penelitian ini menunjukkan bahwa masing-masing hatchery memiliki metode yang berbeda. Pembudidaya paling lama adalah bapak Gusi dan bapak Hasan (30 tahun). Ne di hatchery bapak Hasan dan bapak Gusi adalah 66.667 dan nilai F adalah 0,00749 dan nilai kehilangan alel (P) adalah 0,26183. Dibandingkan dengan pembudidaya bapak Yahya (5 tahun) memiliki Ne = 133.333, F = 0,00375 dan P = 0,06855. Meskipun penetasan di hatchery bapak Hasan dan bapak Gusi memiliki nilai Ne, F dan P yang sama, tetapi hasil struktur populasinya adalah populasi pendiri yang berbeda. Hatcheri bapak Hasan memiliki struktur yang unik dan komposisi alel dibandingkan dengan pembenihan lainnya.

    International audience; In March 2020, the World Health Organization (WHO) defined the outbreak of COVID-19 disease, caused by the SARS-CoV-2 virus, like a pandemic. In the meantime, the first cases of COVID-19 in Brazil were identified. Despite the start of the vaccination campaign in Brazil in January 2021 and in several other countries, the demand for immunizers is still much higher than the supply of doses. Thus, the pandemic should still be a reality for a long time, requiring actions of surveillance, mitigation, or even suppression of the cycle of transmission of the disease. Mathematical-computational models are important tools for the analysis and diagnosis of the pandemic, which can indicate how to prevent new outbreaks or how to control current ones. Such models can also help to understand qualitative and quantitative characteristics of the propagation process of COVID-19, establishing cause and effect relationships that are vital to guide decision making. Epidemiological data record the history of the pandemic's evolution since its beginnings, encapsulating, among many characteristics, the effects of accelerating or reducing the spread of contagion due to the change in the social behavior of the population of interest. Although these data are subject to the effects of underreporting and delay, there is already a significant amount of spatio-temporal information accumulated in them (12 months of evolution, in all Brazilian cities). Thus, such data emerge as an important source of information about the dynamics of COVID-19, which can be explored (without ad hoc considerations) via machine / artificial intelligence learning techniques, with a view to extracting coherent structures/patterns that reveal relevant characteristics about the spread of the disease in Brazilian soil. This work proposes to develop a study of the spatial-temporal dynamics of COVID-19 in Brazilian states, using models based purely on data, ie, without any ad hoc hypothesis, constructed with the aid of two state-of-the-art techniques in statistical learning, they are: (i) Dynamic Mode Decomposition (DMD), which in some sense combines dimension reduction (principal component analysis) and spectral content analysis (Fourier transform) to extract coherent patterns in spatiotemporal data; (ii) Sparse Identification of Nonlinear Dynamics (SINDy), which seeks to reconstruct in a non-parametric way the law of evolution associated with data, imposing a sparse representation (which facilitates interpretation) to the function dictionary that generates the identified equations. COVID-19 data from Brazilian states and capitals are used to test the proposed framework.
