Kacang Panjang (Vigna sinensis L.) merupakan salah satu tanaman sayuran sebagai sumber vitamin dan mineral. Kacang panjang (Vigna sinensis L.) juga merupakan jenis kacang-kacangan yang banyak diusahakan di Indonesia. Desa Gunung Selamat merupakan salah satu desa dengan penghasilan tanaman palawija yang beragam salah satunya kacang panjang (Vigna sinensis L.). Namun, pengabdian masyarakat ini dilakukan karena banyak permasalahan yang dihadapi oleh petani sehingga menyebabkan pertumbuhan kacang panjang (Vigna sinensis L.) menurun. Turunnya produksi ini antara lain disebabkan oleh iklim, tanah, pupuk, hama dan penyakit. Maka dari itu pengabdian masyarakat ini dilakukan untuk meningkatkan pertumbuhan tanaman serta mengurangi penggunaan pupuk sintetik yang dapat merusak ekosistem tanah, maka dari itu diberi perlakuan penyiraman pupuk organik cair pada tanah serta penyemprotan pestisida nabati dari daun pepaya untuk mencegah hama dan penyakit yang menyerang tanaman kacang panjang (Vigna sinensis L.). Perlakuan ini dibuat untuk melihat hasil respon tingkat pertumbuhan pada tanaman kacang panjang (Vigna sinensis L.). AbstrackLong beans (Vigna sinensis L.) are a vegetable plant as a source of vitamins and minerals. Long beans (Vigna sinensis L.) are also a type of legume that is widely cultivated in Indonesia. Gunung Selamat Village is one of the villages with a variety of agricultural crops, one of which is long beans (Vigna sinensis L.). However, this community service was carried out because of the many problems faced by farmers, which caused the growth of long beans (Vigna sinensis L.) to decline. The decline in production was caused, among others, by climate, soil, fertilizers, pests and diseases. Therefore, this community service is carried out to increase plant growth and reduce the use of synthetic fertilizers that can damage the soil ecosystem, therefore it is given the treatment of sprinkling liquid organic fertilizers on the soil and spraying vegetable pesticides from papaya leaves to prevent pests and diseases that attack long bean plants (Vigna sinensis L.). This treatment was designed to see the results of the growth rate response in long bean plants (Vigna sinensis L.).

<p>Breeding kara benguk with mutation induction techniques using gamma ray radiation is expected to produce genetic diversity. The purpose of the study is to determine the value of Lethal Dose 50 (LD50) and obtain the genetic diversity of the kara benguk plant. The research was conducted at PAIR BATAN and Agrotechnology experiment, Universitas Labuhanbatu from May-July 2020. The planting material used was kara benguk seeds. The method used was Randomized Complete Group Design (RCGD) with one factor which was dose of irradiation with six levels (0, 200, 250, 300, 350 and 400 Gy) and three replications. Each replication consisted of 20 plants, so there are a total of 360 experimental plants. The results showed that the value of LD50 kara benguk in 3 weeks after planting was 281,472 Gy. Gamma ray irradiation increases the high genetic diversity of plants and the number of leaves at a dose of 350 Gy.</p>

Berbelanja saat ini telah menjadi suatu yang  telah berkembang secara luas baik dengan sistem online maupun secara langsung. Namun sebelum berbelanja biasa orang lebih tertarik dengan berbagai strategi pemasaran yang ditawarkan. Berbagai strategi yang ditawarkan pada dasarnya merupakan daya tarik untuk memancing pelanggan agar berbelanja. Salah satu yang menjadi bahan diskusi penulis adalah “Rumah Oxcart” yang membuka konveksi  yang berupa kaos, jaket dan kemeja. Untuk mengetahui daya tarik dan strategi pemasaran Rumah Oxcart terhadap kepuasan berbelanja maka peneliti melakukan penelitian dengan menggunakan metode penelitian kuantitatif, dengan pengumpulan data berupa penyebaran kuesioner kepada para pelanggan yang berbelanja di Rumah Oxcart. Hasil penelitian didapatkan bahwa terdapat pengaruh yang signifikan  antara Daya Tarik dan Strategi Pemesaran terhadap Kepuasan Berbelanja di Rumah Oxcart.

The increase in market demand red spinach (Amaranthus Gangeticus) makes the prospects very promising less than optimal for the growth of red spinach (Amaranthus Gangeticus) because soil fertility is low so that the provision of organic material can improve soil fertility through the improvement of the physical, chemical, and biological soil so that it can support the growth of red spinach. This study aims to determine the dose of manure, the dosage of rice husk ash as well as the interaction of dosage that is optimal for the growth and yield of red spinach.this research was conducted experimental farm of the faculty of science and technology with a height of 28 meters above sea level Labuhanbatu district in March to October 2020. Research design using group factorial consisting of two factors. The first factor, namely the granting of cow manure (L) with three levels, namely : L0 = 0 ton/ha (control) L1 = 2 ton/ha, equivalent to 200 g/m2 (the recommended dose), L2 = 4 ton/ha, equivalent to 400 g/m2, L3 = 6 ton/ha, equivalent to 600 g/m2. The second factor, rice husk ash (A) consists of 4 levels, namely : A0 = 0 ton/ha (control), A1 = 1 ton/ha equivalent to 50 g/m2 (the recommended dose), A2 = 1.5 tons/ha, equivalent to 75 g/m2.The Parameters measured were plant height (cm), number of leaves (strands), Weight per Plant Sample (g). The results showed that the administration of cow manure 4 ton/ha, equivalent to 400 g/m2 can increase plant height, leaf number, and weight per Plant of amaranth red. The provision of 1.5 tons/ha, equivalent to 75 g/m2 can increase plant height, the number of leaves plant red spinach (Amaranthus Gangeticus).Keywords: Rice Husk Ash, Red Spinach, Cow Manure, Plant Growth
