Abstract

Website sekolah merupakan gerbang utama untuk mengetahui berita penting, profil sekolah, guru-guru yang mengajar dan info-info terbaru. Website dapat juga digunakan untuk mendukung kegiatan belajar mengajar di sekolah. Disini kami mengambil studi kasus pada MTS I’anatut Tholibi Lamongan yang belum mempunyai website sekolah. Pertama, kami melakukan kajian website yang cocok untuk dikembangkan pada sekolah tersebut. Kami mendapatkan kajian yang berupa: 1. Sekolah belum mempunyai website sama sekali, 2. Guru-guru dan tendik belum terbiasa menggunakan media website sebagai pendukung kegiatan belajar mengajar, 3. Konten yang akan diunggah di website sekolah harus diatur sedemikian sehingga dapat menunjang pembelajaran. Alamat domain sekolah telah dibuat dan dapat diakses melalui www.ianatuttholibin.sch.id. Kegiatan pelatihan juga dilakukan untuk meningkatkan kompetensi guru-guru dalam mengembangkan kegiatan belajar mengajar melalui website. Konten-konten terkait pembelajaran dapat diakses oleh siswa melalui website sekolah. Hasil dari pengabdian masyarakat ini adalah website sekolah, publikasi media massa, jurnal nasional dan juga video cipta.

Abstract

The distillation column is one of the vital components in the biodiesel industry equipment, functioning to separate biodiesel compounds from other compounds such as glycerin and residual methanol. This research aims to analyze future predictions of distillation column prices based on the specified equipment specifications. This type of research is quantitative research with a descriptive approach. The type of research used in this study is quantitative descriptive research with a case study approach and technical simulation. In this study, the methodology used to estimate distillation equipment costs in biodiesel production involves a comprehensive two-stage approach: Equipment specifications are determined based on production capacity, and then price estimates are carried out using the Peters & Timmerhaus formula. In this research, the sample used is technical and economic data related to distillation column design in the biodiesel industry. The calculation data is compared with actual prices on the market to validate the accuracy of the method. The data analysis technique used is economic engineering estimation calculations accompanied by empirical comparisons. The research results show that increasing production capacity requires larger distillation column specifications, such as tower diameter, tower height, and number of holes in the tray, and more complex supporting accessories to support optimal performance. Price comparison shows that the estimation method using the Peters & Timmerhaus formula produces fairly accurate predictions of current market prices. These findings imply that this method can be used as an adequate approach to planning the procurement of distillation columns in the biodiesel industry more efficiently. The implications of this research show that optimal distillation column design not only increases the efficiency of the biodiesel purification process but also significantly reduces operational costs and initial investment. From a technical perspective, proper design can increase product purity, reduce energy consumption, and extend equipment life, ultimately improving overall plant performance.

Abstract

Desa digital merupakan sebuah program yang dirancang oleh pemerintah dalam mendukung smart cities, khususnya program digitalisasi di segala aspek demi meminimalkan adanya kesenjangan terhadap informasi di wilayah pedesaan dengan memanfaat teknologi informasi dan komunikasi yang telah berkembang. Platform desa digital akan berfokus pada berbagai kebutuhan informasi, pelayanan, dan perekonomian. Pemerintah sangat menganjurkan berbagai desa untuk berevolusi menjadi desa digital. Adanya internet tidak serta merta dapat mewujudkan desa digital karena ada beberapa hal yang harus dipersiapkan. Hal yang harus diperhatikan dan dipersiapkan menuju desa digital adalah membangun infrastruktur, membangun teknologi desa, dan menyediakan perangkat pintar yang sesuai dengan kebutuhan masyarakat desa. Bentuk pengabdian masyarakat yang dilakukan di Desa Kudu berupa pengembangan website profil desa, sebagai langkah awal menuju desa digital. Website yang dibuat berisikan informasi terkait desa Kudu, potensi desa dari sisi sosial dan ekonomi. Website juga dapat dijadikan sebagai portal untuk masuk ke sistem informasi lainnya yang dapat dikembangkan lebih lanjut. Langkah-langkah yang telah dilakukan menggunakan kaidah-kaidah pengembangan perangkat lunak yang meliputi: analisis kebutuhan user, desain User Interface, implementasi, coding, serta deployment di webserver. Dilakukan pula pelatihan untuk pengelolaan website yang telah dibangun, baik dari sisi konten maupun pemeliharaannya.

Abstract

Although the Durand-Kerner method is widely used across various fields of computer science, especially in numerical computing, it continues to encounter challenges in locating roots of high-degree polynomials, such as issues with accuracies of roots of the polynomial zeros. Our initial tests and observations on several methods for finding polynomial roots revealed that the roots' accuracy starts to degrade noticeably for polynomials where the degree exceeds 10. Based on considerations of algebraic concepts involving polynomial vector spaces, we introduce an improvement of the Durand-Kerner algorithm aimed at improving root precision. This approach includes targeted refinements in coefficient evaluation, identification of root types, and iterative polishing techniques. We also conducted a comparative evaluation to assess its effectiveness against the original Durand Kerner method and MATLAB's roots() function. Overall, the enhanced algorithm delivers superior accuracy for complex roots—particularly in cases involving multiple zero or integer roots—outperforming both benchmarks, but its execution time increases substantially with polynomial degree.
