Abstract

Cassava is a plant that is ranked third as a source of food in Indonesia. Apart from that, cassava is also needed in industries such as making tapioca flour. In 2021, cassava production in Lampung will be around 20-25 t/ha, this amount is still below the potential of superior cassava which reaches 35-40 t/ha. Cassava growth and production depend on the variety and land where it is cultivated. This research aims to determine the differences in growth and production of several early maturing cassava clones tested, namely Vamas-1, Vati-1, and UTK on Ultisol soil in the PT GGP research area. This research was carried out on the land of the PT GGP research division, Central Lampung, Lampung. This research was carried out from August 2022 to February 2023. The research method used was a Randomized Block Design (RAK) with one treatment, namely clones. There are 3 clones used, namely Vamas-1, Vati-1, and UTK. The experiment on each clone consisted of 3 replications with 36 plants in each replication, but 5 plants were selected from each replication as samples, so that 45 experimental units were obtained. The observation data was analyzed and then compared with the UJ5 clone data based on the Standard Deviation to determine the early maturation characteristics of the three clones. The results showed that clone treatment had no significant effect on growth and production. The number of fresh sweet potatoes at 24 weeks after planting (WAP) in terms of the quantity of clones Vamas-1, Vati-1, UTK, and UJ5 respectively was 7.3; 6.6; 6.3; and 7.3 fruit/plant with a fresh sweet potato weight of 2316,7; 2183,3; 2150,0; and 1433,3 g/plant. The starch content of Vamas-1, Vati-1, UTK, and UJ5 clones was 26,2%; 25,2%; 25,8%; and 23.2%..Keywords : early, Manihot esculenta, UTK, Vamas-1, Vati-1,

Abstract

Perkembangan teknologi digital memberikan peluang untuk mempermudah pengelolaan turnamen olahraga, khususnya sistem gugur yang sering digunakan. Artikel ini bertujuan mengembangkan dan mengevaluasi aplikasi Tournicraft sebagai solusi untuk menyusun jadwal dan bagan pertandingan secara otomatis. Metode penelitian menggunakan studi literatur dan wawancara dengan yang berpengalaman dalam mengelola turnamen sebagai calon pengguna. Hasil pengembangan aplikasi berbasis antarmuka baris perintah (CLI) menunjukkan kemudahan penggunaan dan efisiensi dalam pengelolaan data tim serta penjadwalan pertandingan. Namun, aplikasi masih membutuhkan perbaikan pada validasi input dan stabilitas sistem. Kesimpulannya, Tournicraft layak digunakan untuk turnamen lokal berskala kecil hingga menengah dengan potensi pengembangan fitur lebih lanjut untuk meningkatkan keandalan dan kenyamanan pengguna.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui seberapa efektif penggunaan media digital bersama dengan metode ceramah dalam mengajar Akidah Akhlak, khususnya tentang subjek Kematian dan Kehidupan di Alam Barzakh. Selama PPL di MA Al Mu’min Muhammadiyah, Temanggung, penelitian ini dilakukan. Wawancara dengan siswa dan guru pamong, observasi di kelas, dan analisis dokumen pembelajaran adalah semua metode yang digunakan untuk mengumpulkan data. Hasil penelitian menunjukkan bahwa menggunakan kombinasi metode ceramah dan media digital tidak hanya meningkatkan pemahaman kognitif siswa tetapi juga membuat mereka tertarik dan mengingat nilai-nilai spiritual. Penelitian ini mendorong guru untuk menggunakan teknologi untuk menyampaikan materi agama secara lebih kontekstual dan efisien.
