Abstract

This study aims to analyze the feasibility of increasing the price and production costs of rice farming in the West District of Magetan Regency. The results of the analysis show that the R / C analysis is 1.42,> 1. This means that the costs incurred are Rp. 1, can generate receipts of Rp. 1.42. Therefore, the feasibility of increasing prices and costs of rice farming in the West District of Magetan Regency is still considered feasible because it still provides benefits for rice farmers.

Abstract

Selada (Lactuca sativa L.) termasuk dalam famili Asteraceae yang merupakan salah satu komoditi yang memiliki nilai komersial dan prospek yang baik. Produktivitas tanaman selada di Indonesia mengalami peningkatan setiap tahunnya, namun adanya hama selada masih menjadi masalah tersendiri bagi petani selada. Ulat yang dikenal menyerang tanaman selada adalah ulat grayak (Spodoptera litura F) kehilangan hasil akibat serangan hama S. litura dapat mencapai 80% bahkan puso jika tidak dikendalikan. Salah satu tanaman pestisida nabati adalah tanaman tembakau (Nicotianae tabacum L.) Bagian yang sering digunakan adalah bagian daun dan batang. Daun tembakau kering mengandung 2–8% nikotin. Tanaman lain sebagai penghasil pestisida alami adalah tanaman mimba. Pestisida asal mimba mempunyai tingkat efektivitas yang tinggi dan berdampak spesifik terhadap organisme pengganggu. Beberapa penelitian membuktikan bahwa tingkat mortalitas pada pestisida nabati yang mengandung kombinasi daun mimba adalah mencapai 53%. Ini membuktikan bahwa daun mimba dapat dicampur dengan bahan lain agar efektifitasnya semakin meningkat. Penelitian menggunakan komposisi pestisida nabati tembakau dan mimba dengan konsentrasi 400 g/liter, 500 g/liter, dan 600 g/liter, dan juga dosis aplikasi 10 ml, 20 ml, dan 30 ml. Kombinasi dari masing-masing perlakuan diulang sebanyak lima kali ulangan. Penelitian dilakukan didalam ruangan laboratorium, dan larva ulat grayak diletakkan pada kotak pemeliharaan. Hasil penelitian menunjukkan bahwa komposisi tembakau dan daun mimba pada konsentrasi 600 g/liter dandengan dosis 20 ml efektif dalam menyebabkan mortalitas total larva S. litura F, selama 4 hari.

Abstract

The Java-Bali electricity system is the largest electricity system in Indonesia which consists of 5 areas including Jakarta-Banten area, West Java area, Central Java area, East Java area and Bali area. This system is operated to meet the economic, reliability, quality, and green principles. In the case of reliability, one of the essential aims is minimization of transmission losses due to importance in system improvement to increase system operational efficiency to the possible extent. Transmission losses are an inevitable part of the electric power transfer process from generation stations to consumers. The power losses in a transmission line are inversely proportional to the square of the line voltage. This implies that lower line voltages result in higher power losses. Therefore, it is crucial to maintain optimal voltage levels to minimize transmission losses and ensure efficient energy delivery across the power system. One effective way to achieve this is by integrating capacitors into the system. In this study, we have explored two methods that aim to pinpoint the most advantageous locations for the integration of new capacitors. The goal is to optimize capacitor planning, with an emphasis not only on improving voltage levels but also on minimizing transmission losses within the Java-Bali system. The research results indicate that implementing two proposed methods can significantly reduce transmission losses in The Java-Bali system. Method-1 involves identifying the lowest voltage over the course of a year, while Method-2 focuses on the lowest voltage value within the first quartile (Q1/25%) during the same period

Abstract

Vitamin D deficiency and dental cavities are global issues. Thus, the purpose of the study is to investigate how dental caries in school-age children from the Peshawar district is affected by vitamin D insufficiency. The study included 1600 kids ranging in age from 4 to 15 years old. To obtain samples, a methodical random sampling procedure was used. In the current study, 1600 samples were calculated to investigate vitamin D deficiency in children enrolled in school. Men were found to have a significant percentage of vitamin D insufficiency (22.5%), but female had a relatively low ratio (12.5%). Male students made up 220 (27.5%) of the school-age population, while female students made up 100 (12.5%). Both genders had significant rates of insufficiency. Age-appropriate investigation. Male students made up 220 (27.5%) of the school-age population, while female students made up 100 (12.5%). Both genders had significant rates of inadequacy. The investigation of vitamin D deficiency according to age reveals that very low frequency was found in the low aged group (4–7 years) 80 (10%), similarly low frequency was found in the 8–11 years group 120 (15%), and very high frequency was found in the 12–15 years group 160 (20%). According to the data broken down by residency, children living in urban areas had a high frequency ratio of 160(20%) compared to 120(15%) for children living in rural areas. Long-term health effects are associated with the growing issue of vitamin D insufficiency and its relationship to school-age children's intellectual performance. The current investigation demonstrated the connection between investigation of vitamin D deficiency according to age, gender, and socioeconomic position.

Abstract

Trenggalek merupakan sebuah kabupaten yang terletak di Jawa Timur. Saat ini, Trenggalek memiliki Agrowisata Dilem Wilis dengan luas 40 hektar. Terdapat objek wisata sejarah berupa bangunan penggilingan kopi peninggalan Belanda, Kandang sapi perah dan kafe yang menyajikan produk dari hasil Alam Dilem Wilis. Salah satu kekurangan di agrowisata Dilem Wilis saat ini adalah minimnya penerangan, hal ini menyebabkan jalan gelap dan membatasi akses di malam hari. Terletak jauh di atas bukit menjadi salah satu penyebab minimnya penerangan, karena terbatasnya jangkauan aliran listrik PLN. Maka dari itu, pada kegiatan pengabdian ini penulis memberikan solusi alternatif dengan memanfaatkan tenaga surya atau PJU-TS (Penerangan Jalan Umum Tenaga Surya) untuk memenuhi kebutuhan penerangan di sekitar spot wisata Dilem Wilis. Kegiatan pengabdian ini memasang sebanyak 4 tiang PJU-TS dengan ukuran tinggi total 550 cm dengan lengan 90 cm. Pada lengan tiang dipasang lampu LED dengan daya 150 Watt. PJU-TS telah terpasang di 4 titik strategis yaitu di area Peternakan sapi, TTP Dilem Wilis, Kafe Dilem Wilis dan Gudang Kopi. Diharapkan dengan adanya PJU-TS ini akan mempermudah akses disaat malam hari dan menarik perhatian wisatawan untuk berkunjung.
