Abstract

This experiment aims to determine the effect of spacing and nitrogen fertilizer on the growth and yield of sorghum (Sorghum bicolor L. Moench) Samurai 2 variety. The experiment was carried out in Mekarjaya Village, Gantar District, Indramayu Regency - West Java. The time of the research was carried out from July to November 2021. The location is located at an altitude of 493 m above sea level (asl), the soil type is the association of Latosol and Regosol, including type C rain (slightly wet). The experimental method used is the experimental method with a factorial randomized block design (RAK), the treatment consists of two factors, repeated three times. The first factor is nitrogen fertilizer which consists of three levels, namely 100 tons/ha nitrogen fertilizer, 150 tons/ha nitrogen fertilizer, and 200 tons/ha nitrogen fertilizer. While the second factor is the spacing which consists of three levels, namely the spacing of 25 cm x 40 cm, the spacing of 25 cm x 50 cm, and the spacing of 25 cm x 60 cm. The main observation data were processed using linear model statistical tests, analysis of variance, and Scott-knot cluster further test analysis. To determine the correlation between the treatment with the components of growth and yield of sorghum, the correlation used is the Product Moment correlation coefficient. 1 The experimental results showed: (1) The combination of plant spacing and nitrogen fertilizer had an effect on leaf area index at 28 HST, 35 HST and 42 HST, and panicle length, but had no significant effect on plant height, number of leaves, stem diameter, root volume, number of panicles per clump, panicle weight per clump, 1000 seed weight, seed weight per clump and dry seed weight per plot, (2) The highest seed weight per plot was produced by the combination of treatment G, namely 25cm x 60 cm spacing and 100 kg urea fertilizer with an average The average weight was 3.79 kg (equivalent to 6.314 tons/ha), but it was not significantly different from the other treatment combinations, (3) There was a significant correlation between plant height at 42 HST and seed weight per plot in the tall category. However, there was no significant correlation between plant height at 28 HST (very low category) and 35 HST (low category) and the number of leaves at 28 HST (very low category), 35 HST (very low category) and 42 HST (very low category). low category) with dry seed weight per plot

Abstract

This study aims to determine the influense of the type of manure and the age of seedlings on the growth and yield of cayenne pepper plants (Capsicum frutescent L). This research was conducted in Bayalangu Kidul Village, Subdistricts of Gegesik, District of Cirebon – West Java, from March until Juny 2018. The Method used to experimental method using a Rendomized Blok Design patterns, treatment consists of two factors were repeted three times. The first factor is a type of manure consists of chicken manure, goat manure and cow manure. While the second factor is age of seed consists of age of seed 20, 30 and 40 days after seedling. The results of the study showed the real difference between types of manure and age of seedlings against plant height, number of leaves, number of fruit cropping and planting as well as fruit weight cropping and planting. On the treatment A (chicken manure and 20 days after seedling), B (chicken manure and 30 days after seedling), C (chicken manure and 40 days after seedling), E (goat manure and 30 days after seedling) and F (goat manure and 40 days after seedling) increase the weight of the fruit.
RESPON MORFO-FISIOLOGI TANAMAN BAWANG MERAH PADA VARIASI KEDALAMAN PARIT, DOSIS PUPUK ORGANIK DAN FREKUENSI PENYIRAMAN Nur, Subandi; Saparso, Saparso; Susanto, Niken Hapsari Arimurti

Abstract

Teknik budidaya bawang merah yang umum dilakukan oleh petani di Kabupaten Brebes dan sekitarnya antara lain dalam pembuatan parit antar bedengan dengan lebar parit 50 cm. dan kedalaman parit 60 – 70 cm. Dengan kedalaman parit 60 – 70 cm., maka petani harus mengeluarkan biaya pengolahan tanah yang relatif besar dan membutuhkan waktu yang relatif lebih lama. Salah satu cara untuk memperbaiki kualitas tanah adalah dengan pupuk organik, sehingga dapat menyebabkan tanaman tumbuh dengan baik. Tujuan penelitian yang akan dicapai adalah : Mengetahui respon morfo-fisiologi tanaman bawang merah pada perlakuan variasi kedalaman parit, dosis pupuk organik dan frekuensi penyiraman serta mengetahui adanya interaksi antara variasi kedalaman parit dan frekuensi penyiraman yang diujikan dilihat dari variabel pertumbuhan dan hasil bawang merah. Penelitian dilakukan di Desa Pulosari Kecamatan Brebes Kabupaten Brebes selama tiga bulan (April sampai dengan Juni 2020). Penelitian dilakukan dengan menggunakan Rancangan Petak Terbagi (Split Split Plot Dsign) dengan rancangan dasar RAKL dan diulang 3 (tiga) kali. Faktor yang dicoba adalah : 1. Petak Utama : Kedalaman Parit (P) : P1 = 30 cm., P2 =50 cm. dan P3 = 70 cm. 2. Anak Petak : Pupuk Organik (O) : O1= 0 ton/ha, O2 = 17,5 ton/ha dan O3 = 35 ton/ha. Anak-anak Petak : Frekuensi Penyiraman (F) : F1 : 1 kali sehari dan F2 : 2 kali sehari.   Data yang diperoleh dianalisa dengan menggunakan analisis sidik ragam pada taraf kesalahan 5 %, apabila terjadi perbedaan nyata dilanjutkan dengan Uji Beda Nyata Terkecil (BNT) taraf 5 %. Hasil penelitian menunjukkan : Kadar lengas tanah tertinggi pada interaksi perlakuan kedalaman parit 70 cm, pupuk organik 35 ton/ha dan frekuensi penyiraman dua kali sehari (P3O3F2) (38,55 mm.10 cm-1).         Kata Kunci: Bawang merah, Kedalaman parit, Pupuk organik, Frekuensi penyiraman, morfo-fisiologi.

Abstract

This study aims to find out what factors shape the production system of the sticky tape business, and find out how to model the dynamic system of the sticky tape business for the next 10 months. The research data were obtained from interviews with respondents who owned sticky tape businesses. Based on the research results, there are three sub-systems in the sticky tape production system, namely the raw material sub-system and raw material costs, the production sub-system and the sales value (receipt) sub-system, income and business feasibility. Dynamic system modeling in the sticky tape business for the next 10 months is carried out using a scenario approach without improvement and scenario with improvement. The average income per month in the scenario without improvement is Rp. 12,996,269, - and a scenario with an improvement of Rp. 17,200,732,-,- with a feasibility value in the scenario without improvement of 1.84 and the scenario with improvement of 2.01.Keywords : Simulation, Dynamic, Business, Sticky, Tape
