Bunga kol (Brassica oleracea var.botrytis L.) merupakan salah satu hasil pertanian yang mudah rusak, guna menangani permasalahan tersebut, perlu dilakukan pengawetan untuk mempertahankan mutu bunga kol. Salah satu teknik yang dapat digunakan untuk pengawetan tersebut adalah perendaman dengan garam dapur (NaCl). Tujuan penelitian ini adalah untuk mengetahui pengaruh kosentrasi air garam dan lama perendaman terhadap mutu bunga kol selama penyimpanan dingin dan untuk mengetahui kosentrasi garam terbaik terhadap mutu dan lama perendaman yang terbaik pada bunga kol. Metode penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari dua faktor, yaitu perlakuan kosentrasi NaCl dan lama perendaman, pengukuran berlangsung selama 10 hari dengan 2 kali ulanganrlakuan kosentrasi garam dapur (NaCl) sebanyak 3%, 6%, 9% dan lama perendaman 10, 20 dan 30 menit. Hasil penelitian setelah proses analisis menggunakan aplikasih SPSS 16 sebagai alat bantu pengolah data dalam menentukan pengaruh variabel penelitian terhadap objek penelitian serta dilakukan uji duncan untuk menentukan perbedaan hasil dari setiap perlakuan. Hasil penelitian menunjukan bahwa perendaman menggunakan garam dapur (NaCl) 10gram dengan konsentrasi 6% dan waktu perendaman selama 20 menit menunjukan hasil terbaik setelah dilakukan pengamatan selama 10 hari. Cauliflower (Brassica oleracea var. botrytis L.) is one of the perishable agricultural products. Handling these problems, preservation is necessary in order to maintain the quality of cauliflower. One technique that can be used for preservation is soaking with salt (NaCl). The purpose of this study was to determine the effect of salt water concentration and soaking time on the quality of cauliflower during cold storage and to determine the best salt concentration on quality and the best soaking time on cauliflower. This research method uses a Completely Randomized Design (CRD) consisting of 10 treatments and 2 replications with a concentration of salt (NaCl) of 3%, 6%, 9% and soaking time of 10, 20 and 30 minutes. The results of the study after the analysis process using SPSS 16 as a data processing tool in determining the effect of research variables on the research object as well Duncan to determine the difference in the results of each treatment. The results showed that soaking using table salt (NaCl) 10 grams with a concentration of 6% and soaking time for 20 minutes showed the best results after 10 days of observation.

ABSTRACTThe aim of this study was to determine the interaction between guano walet administration and reduction of SP-36 fertilizer on growth and yield of flower cabbage; to find out the effect of guano walet on the growth and yield of flower cabbage; and to find out the effect of SP-36 fertilizer reduction on growth and yield of flower cabbage. The study was conducted from May to August 2018. This study used a completely randomized design (CRD) consisting of 2 factors namely guano walet with a reduction in SP-36 fertilizer, 4 x 4 factorial pattern with 3 replications. The variables observed were the number of leaves, flowering age, plant wet weight, fresh weight of flowers, and diameter of flower crop. The results showed that the combination of 100% guano walet administration with a reduction of SP-36 0% on spodosol soil gave the best results for the number of leaves with an average value of 16.00 strands at 6 weeks after planting and fresh flower weight of 166, 76 g. Guano walet administration on spodosol soil with a dose of 100% gave the best results on the number of leaves by 25.83 strands at the age of 9 weeks after planting, flowering age of 79.33 day, plant wet weight of 326.82 g and the results showed that the combination of 100% guano walet administration with a reduction of SP-36 0% gave the best results for the diameter of flower cropwith an average value of 12,15 cm.Key words: cabbage flower, guano walet, SP-36 fertilizer, spodosolsABSTRAKTujuan dari penelitian ini adalah untuk mengetahui interaksi antara pemberian guano walet dengan pengurangan pupuk SP-36 terhadap pertumbuhan dan hasil kubis bunga; untuk mengetahui pengaruh pemberian guano walet terhadap pertumbuhan dan hasil kubis bunga; dan untuk mengetahui pengaruh pengurangan pupuk SP-36 terhadap pertumbuhan dan hasil kubisbunga.Penelitian dilaksanakan mulai dari bulan Mei sampai Agustus 2018. Penelitian ini menggunakan rancangan acak lengkap (RAL) yang terdiri dari 2 faktor, yaitu pemberian guano walet dengan pengurangan pupuk SP-36, pola faktorial 4 x 4 dengan 3 ulangan. Variabel yang diamati adalah jumlah daun, umur berbunga, bobot segar total tanaman, bobot segar bunga, dan diameter krop bunga. Hasil penelitian menunjukkan bahwa kombinasi pemberian guano walet 100% dengan pengurangan SP-36 0% pada tanah spodosol memberikan hasil terbaik jumlah daun dengan nilai rata-rata sebesar 16,00 helai tanaman-1 pada umur 6 minggu setelah tanam dan bobot segar bunga 166,76 g tanaman-1. Pemberian guano walet pada tanah spodosol dengan dosis 100% memberikan hasil terbaik terhadap jumlah daun sebesar 25,83 helai tanaman-1 pada umur 9 minggu setelah tanam, umur munculnya bunga pada hari ke- 79,33, bobot segar total tanaman sebesar 326,82 g tanaman-1dan pada variabel diameter krop bunga pemberian guano 50% dengan pengurangan pupuk SP-36 0% memberikan hasil sebesar 12,15 cm tanaman-1.Kata kunci: Guano walet, kubis bunga, pupuk SP-36, tanah spodosol

Aedes aegypti, dengue fever mosquito, is primarily associated with the transmission of dengue in tropical and subtropical regions of the world. The present investigations was carried out to assess the larvicidal efficacy of aqueous and ethanol leaf extract of Brassica oleracea var. botrytis L against 4th instar larvae of  Ae.aegypti. The concentration of extracts prepared from the leaf of plant Brassica oleracea var.botrytis L. were screened for their larvicidal activity against early fourth instars of dengue vector. The mortality rate of Ae.aegypti against aqueous and ethanol extracts of B.oleracea as follows 72% and 96%. Ethanol extract exposed to IVth larvae of Ae.aegypti is more efficiency than the aqueous extract. The present investigation suggest the possible use B. oleracea L. as an agent for the control of dengue vector, A. aegypti.
