Winglet adalah aksesoris pada sayap pesawat yang dapat meningkatkan performa tanpa harus memperpanjang bentangan sayap. Winglet memiliki bentuk seperti sirip yang dipasang pada ujung sayap, ataupun berupa ujung sayap yang ditekuk ke arah vertikal. Winglet berfungsi untuk mengurangi gaya hambat yang berupa vorteks pada ujung sayap (tip trailing vortex). Hal tersebut terjadi karena udara bagian bawah sayap yang bertekanan tinggi pada ujung sayap ikut mengalir ke aliran udara bagian atas sayap yang bertekanan rendah yang mengakibatkan terjadinya vortek dis. Metode eksperimen yang akan digunakan pada studi kali ini adalah simulasi menggunakan software Gambit dan Fluent. Dari hasil simulasi yang telah dilakukan, didapatkan performa aerodinamika dan fenomena aliran udara pada ujung sayap dengan hasil yang telah didapatkan yaitu sayap tanpa winglet memiliki nilai efisiensi aerodinamika terkecil dan aliran vortex yang terlihat lebih jelas dibandingkan dengan sayap yang memiliki winglet, sedangkan konfigurasi sayap dengan nilai efisiensi aerodinamika tertinggi dimiliki oleh sayap dengan konfigurasi split winglet.

Gaya angkat pada airfoil terjadi karena adanya tekanan tinggi pada lower surface dan tekanan lebih rendah pada upper surface, aliran udara yang berada pada upper surface setelah melewati leading edge akan dipercepat sehingga gradien tekanan pada upper surface akan bernilai negatif. Selanjutnya setelah aliran udara berada pada puncak airfoil, aliran diperlambat dan gradien tekanan akan bernilai positif. Ketika momentum aliran tidak dapat melawan adverse pressure gradien maka akan terjadi sparasi atau stall. Maka dari itu digunakannya Vortex generator untuk menunda separasi atau stall. Dalam tugas akhir ini, penulis akan melakukan simulasikan menggunakan computational fluid dynamic (CFD) mengenai pengaruh vortex generator dengan bentuk triangular, rectangular, dan curve – edge dengan susunan straight pada wing dengan airfoil NACA 0012 pada kecepatan 10(m/s). Dengan adanya vortex generator ini dapat menaikkan momentum aliran di dekat dinding airfoil sehingga dapat lebih tahan terhadap adverse pressure gradien dan menunda separasi. Dengan tertundanya separasi akan menaikkan gaya angkat (lift) dan menurunkan gaya hambat (drag) force pada airfoil sehingga dapat meningkatkan performansi airfoil tersebut. Hasil penelitian ini mendapatkan kesimpulan bahwa vortex generator sangat berpengaruh dalam menunda terjadinya separasi pada permukaan wing dan vortex generator berbentuk reqtangular paling baik nilai efisiensi Cl/Cd daripada vortex generator lainnya.

Increased interest in the use of vortex turbines as a renewable energy source. more advantages compared to axial turbines in general. The aim of this applied research is expected to be able to increase the power and efficiency of vortex turbines, achieving the target efficiency output of >30% from the previous research output of 37% on the performance of single and two-stage turbines with an angle of 630. The research method is experimental based, the study being carried out at this time with variations in discharge and runner type 630 one stage and Savonius with exhaust channels cut off by 2cm, this was done to determine the response to increasing the efficiency of the vortex turbine. Experimental operational approach with SNI 8277:2016, discharge variation 11-13 l/s. The results of the experimental recording of the application of the runner 630 on one level, obtained that the highest efficiency was a flow rate of 11 l/s with an efficiency of 29%. The treatment of cutting the drain channel had an impact on reducing efficiency.

Enhancing the calibre of personnel within a firm holds significant importance as it not only impacts the overall level of work productivity, but also holds the potential to elevate the quality of performance within the organisation. The objective of quality improvement is to enhance the technical, theoretical, conceptual, and moral competencies of employees, so ensuring their ability to deliver exceptional information to both existing and potential clients. In order to effectively promote these products, it is imperative for staff to possess a comprehensive understanding of the consumer market's desires. The provision of high-quality service is intricately linked to the enhancement of human resources. The objective of this study is to provide a comprehensive description of the technique employed to enhance the quality of work among employees at PT. Mandiri Sawit Bersama. The quantity of samples obtained through the utilisation of the purposive sampling technique. This study employs qualitative descriptive approaches, employing qualitative descriptive analytic tools for data analysis. Based on the findings derived from the conducted research, it was determined that out of the three strategies aimed at enhancing the calibre of human resources inside the organisation, two of them exhibit a comparatively lesser impact on the overall quality of human resources in the company. This observation indicates that the strategy is not implemented in a direct manner, but rather its impact is confined to influencing the performance of employees in executing assigned duties.

Desa Wangen Glagah di Lamongan memiliki potensi pertanian yang besar namun masih menghadapi tantangan dalam hal ketergantungan pada pupuk kimia dan pestisida sintetis yang berdampak negatif pada lingkungan dan kesehatan masyarakat. Untuk mengatasi masalah ini, program pengabdian masyarakat dengan fokus pada optimalisasi pertanian ramah lingkungan melalui pelatihan pembuatan pupuk organik cair dan penganggulangan hama secara alami. Kegiatan ini bertujuan untuk meningkatkan kesadaran dan pengetahuan petani tentang pentingnya penggunaan pupuk organik cair serta metode pengendalian hama alami. Pelatihan ini melibatkan 38 peserta yang terdiri dari petani lokal dan perwakilan perempuan. Metode yang digunakan meliputi penyuluhan, demonstrasi, dan praktik langsung pembuatan pupuk organik cair menggunakan bahan-bahan alami seperti kotoran ternak, sisa tanaman, dan mikroorganisme lokal. Selain itu, peserta juga diajarkan berbagai teknik pengendalian hama alami, seperti penggunaan tanaman penolak hama, predator alami, dan pestisida nabati. Hasil dari pelatihan ini menunjukkan peningkatan pengetahuan dan keterampilan para petani dalam membuat dan menggunakan pupuk organik cair serta mengendalikan hama secara alami. Beberapa peserta mengusulkan kepada pemdes, tim pengabdi dan pihak UPT Dinas Pertanian yang hadir, tentang adanya sekolah lapang sebagai sara diskusi petani dan lahan tanaman padi sebagai percontohan penggunaan pupuk organik cair tersebut agar warga melihat prakteknya secara langsung hasilnya.

Humanization of learning emphasizes a responsive and inclusive learning environment and interpersonal relationships between teachers and students are very important for the development of children with autism. The TEACCH method is often used for educational interventions for autistic children in various schools. Without realizing it, SLB Bhakti Pemuda has implemented this method by structuring the school environment to support the learning and development of autistic children. This research aims to determine the learning process of autistic children at SLB Bhakti Pemuda Kediri City and to determine the application of the TEACCH method to autistic children at SLB Bhakti Pemuda Kediri City. The type of research used is field research, namely the author conducts research in the field to obtain data and information. This research uses qualitative research with a descriptive approach, namely the researcher describes the conditions that exist at the research location which are related to the research focus. The results of the research show that the humanization of learning at SLB Bhakti Pemuda Kediri City can be seen from the use of laptop media in mathematics learning for autistic children which is quite effective in supporting their development, although there are several obstacles. Teachers feel that the application of the TEACCH method, which involves environmental planning, has a positive impact on the development of autistic children in the teaching and learning process, such that students more easily accept instructions tailored to their needs and ability level which can increase understanding of the material that has been provided.
