Despite the, information about consumer preference on the quality attribute of the indigenous vegetables is still lack. Thus, the study purposed to determine consumer preferences on the quality attribute of leafy greens basil, kenikir and watercress to improve the quality on the farm level. The research conducted through consumer survey in seven sites, namely Surabaya, Malang, Kediri, Madiun, Jember, Bojonegoro, Pamekasan, East Java Indonesia from July to August 2017. The site selection based on sociocultural and the composition of diverse communities. From seven sites, a total of 210 female respondents interviewed randomly. Consumer preferences on the quality attributes concluded by the method based on rank orders and analyzed with Chi-square. The experimental results showed that consumer preference for quality attributes depend on the vegetable. For basil: leaf color was light green, a large number of leaves, without a flower, medium leaf size (3.5 cm diameter), number of branches/stalk, no spicy taste, and smells stung. For kenikir: leaf color was light green, a large number of leaves, without a flower, medium smell, a large number of branches/stem, the texture of stem not fibrous, and no bitter taste. For watercress: leaf color was green, a large number of leaves, medium stem size, soft leaf, and slightly sweet flavor.

Namun demikian, kriteria kualitas yang diinginkan oleh konsumen masih belum seluruhnya dipetakan, oleh sebab itu, pengkajian dilakukan agar dapat di identifikasi preferensi konsumen terhadap kualitas sayuran kemangi, kenikir dan selada air dalam rangka perbaikan kualitas di tingkat petani. Survei konsumen dilakukan di tujuh wilayah di Jawa Timur, yaitu Surabaya, Malang, Kediri, Madiun, Jember, Bojonegoro, dan Pamekasan pada bulan Juli sampai Agustus 2017. Pemilihan wilayah didasarkan pada sosiokultur dan komposisi masyarakat yang beraneka ragam. Dari 7 wilayah tersebut, wawancara dilakukan dengan total 210 responden wanita yang ditentukan secara acak. Preferensi pengguna terhadap sifat kualitas sayur-sayuran dianalisis menggunakan Chi-square. Hasil analisis menunjukkan bahwa, preferensi pengguna terhadap sifat kualitas tergantung pada jenis sayurannya. Sayur kemangi yang disukai adalah memiliki warna daun muda, jumlah daun banyak, ukuran daun medium (garis tengah 3.5 cm), tidak terdapat bunga, total cabang/tangkai lebat, rasa tidak pedas, dan berbau menyengat.

The experiment was carried out at Margahayu Experimental Garden (± 1 250 m asl.), Indonesian Vegetable Research Institute in Lembang, West Java, from July to October 2015. The experiment was arranged using paired comparisons and each treatment was repeated four times. The treatment tested is how to swing the nozzle with the position: (A) above the plant canopy facing down and moving forward and (B) below and swinging towards the plant at an angle of 45o. Results showed that the second nozzle swinging method (B) gave a higher level of coverage and distribution of droplets than that produced by the first nozzle swinging method, so the pesticide efficacy in treatment B was also higher.

(Lepidoptera: Crambidae) is one of the important insect pests that can reduce production of cruciferous plants. Generally farmers control this insect pest by using synthetic insecticides. However, the intensive and excessive use of synthetic insecticides may cause negative impact to the insect and environment, such as the occurence of resistance and resurgence of pests and chemical residues in agricultural products. One of alternative strategies that can be adopted to reduce the negative impact of synthetic insecticide use is by utilization of botanical insecticide. The aim of this research was to study the activities of extract Averrhoa bilimbi leaves, Annona squamosa seeds, and Tithonia diversifolia flowers on mortality and growth inhibition of C. pavonana larvae. The mortality activity was assessed by single and extract mixture using leaf residual method. The larval growth inhibition activity was also tested by using leaf residual method. A. squamosa extract at concentration of 0.015% could kill 100% of larvae at 72 hours after treatment (HAT). Meanwhile, T. diversifolia extract at 5% could kill 88% of larvae at 144 HAT. Extract mixtures of T. diversifolia and A. squamosa at ratios 1:1, 1:2 and 2:1 (w/w) gave low mortality activity. These three extract showed growth inhibition activity against the larvae of C. pavonana. Keywords: Botanical insecticides, cabbage pest, extract mixture, toxicity ABSTRAK Crocidolomia pavonana (F.) (Lepidoptera: Crambidae) merupakan salah satu hama penting yang dapat menurunkan produksi tanaman kubis-kubisan. Petani umumnya mengendalikan serangan hama ini dengan menggunakan insektisida sintetik. Namun, penggunaan insektisida sintetik yang terus-menerus dan berlebihan dapat menyebabkan dampak negatif pada serangga dan lingkungan seperti terjadinya resistensi dan resurjensi hama serta residu pada produk pertanian. Salah satu strategi alternatif yang dapat dilakukan untuk mengurangi dampak negatif penggunaan insektisida sintetik adalah dengan memanfaatkan insektisida nabati. Penelitian ini dilakukan untuk mengetahui aktivitas ekstrak daun Averrhoa bilimbi, biji Annona squamosa, dan bunga Tithonia diversifolia terhadap mortalitas dan penghambatan pertumbuhan larva C. pavonana. Aktivitas mortalitas diuji dengan ekstrak tunggal dan campuran menggunakan metode residu pada daun. Aktivitas penghambatan pertumbuhan larva C. pavonana juga diuji dengan metode residu pada daun. Ekstrak A. squamosa pada konsentrasi 0.015% dapat mematikan larva C. pavonana sebesar 100% pada pengamatan 72 jam setelah perlakuan (JSP).
