Laporan kerja praktek pengembangan mesin pengayak tepung pada pembuatan bahan pupuk tablet
Get PDFProgram Magang Kedaireka - Solusi Terkini dalam Mewujudkan Kemudahan Sinergi Kontribusi Perguruan Tinggi dengan Komersialisasi Mitra untuk Kemajuan Bangsa Indonesia, Sejalan dengan Visi Kampus Merdeka Kemendikbud RI. Program ini diubah menjadi nilai mata kuliah dan dilaksanakan di PT. Agro Indah Permata 21 mulai 6 September 2023 hingga 20 Desember 2023. Perusahaan ini bergerak di bidang pertanian dan peternakan, berlokasi di Kabupaten Bogor, Jawa Barat. Saat ini, PT. Agro Indah Permata 21 memproduksi pupuk hayati cair dan pakan ternak untuk memenuhi kebutuhan di Indonesia. Produk utama perusahaan meliputi Pupuk Cair Hayati Merk Bravo Nature, Pupuk Cair Hayati Merk Bio Zee, Pestisida Hayati Merk AIP21, Asam Humat Merk Bravo Humat, dan silase untuk pakan ternak yang diproduksi di Subang, Jawa Barat. Dalam implementasi skema magang Kedaireka, saya fokus pada pengembangan mesin pengayak tepung dengan motor ac sebagai penggerak. Sorgum atau garai adalah tanaman serbaguna yang digunakan sebagai sumber pangan, pakan ternak, dan bahan baku industri. Produksi silase memerlukan mesin pencacah sorgum atau chopper. Mesin ini berfungsi memotong atau mencacah sorgum menjadi partikel kecil agar dapat dikonsumsi oleh ternak. Namun, pada saat proses pencacahan, output mesin menghasilkan semburan sorgum yang tidak teratur, menyulitkan pekerja dalam proses pengemasan dan pemberian nutrisi. Tim magang Kedaireka melakukan pengembangan pada mesin ini untuk memastikan semburan sorgum menjadi teratur. Hal ini memungkinkan pemberian nutrisi pada sorgum dapat dilakukan dengan lebih efisien, serta mempermudah proses pengemasan. Dengan adanya perbaikan ini, pekerja dapat mengemas dengan lebih baik dan mencampurkan nutrisi secara merata pada sorgum. Sebagai hasilnya, silase yang dihasilkan menjadi pakan ternak yang lebih baik dan sesuai untuk dikonsumsi oleh hewan
Pengembangan mesin pengayak bahan pupuk tablet dengan dimmer
Get PDFTeknologi memiliki peran krusial dalam mendukung perkembangan kualitas produksi dalam pertanian, membutuhkan pengembangan yang sesuai agar efisiensi kerja dan hasil produksi dapat optimal. Namun, seringkali, teknologi yang telah diciptakan belum sepenuhnya sesuai dengan kebutuhan pekerja di lapangan, sehingga dapat menghambat proses produksi. Oleh karena itu, penelitian ini berfokus pada pengembangan dan penyesuaian mesin pengayak bahan pupuk tablet, sebuah perangkat vital dalam industri pupuk tablet, yang digunakan oleh salah satu perusahaan pertanian di Bogor yaitu PT. Agro Indah Permata 21. Mesin pengayak bahan pupuk tablet saat ini menghadapi kendala utama, yaitu ketidakmampuan untuk mengontrol kecepatan putaran motor AC saat dihidupkan. Keadaan ini menyebabkan mesin beroperasi pada kecepatan maksimal secara langsung, memberikan dampak negatif terhadap kinerja operasional dan keamanan mesin. Dalam rangka mengatasi permasalahan tersebut, penelitian ini bertujuan untuk mengembangkan sistem kontrol kecepatan pada motor AC mesin pengayak bahan pupuk tablet dengan menerapkan dimmer Watt. Metode penelitian melibatkan perancangan dan implementasi sistem kontrol menggunakan dimmer pada motor AC, disertai dengan analisis dampaknya terhadap kinerja mesin. Hasil penelitian menunjukkan bahwa penggunaan dimmer memberikan kontrol yang efektif terhadap kecepatan putaran motor AC, memungkinkan operator untuk mengatur kecepatan secara selektif sesuai dengan kebutuhan operasional. Implementasi dimmer juga membawa dampak positif terhadap peningkatan keselamatan operasional dan umur mesin. Penelitian ini diharapkan memberikan kontribusi signifikan dalam meningkatkan efisiensi operasional mesin pengayak bahan pupuk tablet di industri pupuk tablet. Implikasi praktis dari pengembangan sistem kontrol kecepatan ini meliputi peningkatan stabilitas operasional, pengurangan tekanan pada struktur mesin, dan peningkatan keamanan kerja bagi operator. Dengan demikian, penelitian ini menjadi langkah penting dalam mengoptimalkan peran teknologi dalam mendukung pertanian modern
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
