Abstract

ABSTRACT   Aquatic insects are one of the organisms that are used in determining water contamination. Aquatic insects are sensitive to the presence of waste dumped in the river and some are resistant to such waste. One of insect resistant waste is Chironomidae. The research objective was to determine aquatic insect species, population abundance by calculating indices diversity and biotic index. Aquatic insects in the lake watershed Tondano were collected by kicks and Hand Picking. Result showed that seven orders, theerteen families and sixteen species had been identified. The number of highest aquatic insect was found in Noogan which were 13 species, whereas in karondoran were 9 species. Aquatic insects were identified including, Heptagenia sp, sp Baetis sp, Caenis sp., Hydropsyhe, sp and Chrironomidae. The highest aquatic insect populations were collected in Karondoran followed by Winebetan and Noogan. The highest diversity index of aquatic insects was found in Winebetan whereas the lowest was in Karondoran. The lowest value of the biotic index was identified in the region Noogan suggested that water in Noogan area was clean water compared to Winebetan and Karondoran.

Abstract

ABSTRACT   Searching the plants in which can produce biopesticides, such as antifeedant to control the insect pests, it attracted the attention of worldwide researches. It is due to in the crop protection, the compounds of antifeedant do not kill, repel or entrap insects, but just inhibit the insect's appetite, so that the food crops or the commodity can be protected. Plutella xylostella (L) is the insect pests which is cosmopolitantly distributed in. Its attacks could damage vegetables resulting in loss of quantitative and qualitative. To overcome these problems, need to develop a means of pest control, which are effective but environmental friendly. North Sulawesi has a lot of plants, which is potentially developed as a source of botanical insecticides. Pangi Plant (Pangium sp.) is a plant species which potentially developed and effective against several types of insect pests, but testing by using crude extract can give varies results depending on the type of extract used, the test insects and environment factors. The purpose of this study was to determine the potential of leaf extracts pangi (Pangium sp.) as antifeedant against Plutella xylostella. The method used is the method of Qin et al. (2004). To determine the class of active compounds to extract the thick antifeedant have done by taking each extract to make a concentrations of 1% (w / v), 5% (w / v), and 10% (w / v). Data were analyzed by Analysis of Variance (One-way ANOVA). The results showed that, the leaf extract of condensed pangi were able to inhibit the feeding activity of the larvae of P. xylostella. Keywords : biopesticide, Pangium sp., Plutella xylostella ABSTRAK   Penelusuran tumbuh-tumbuhan yang dapat menghasilkan biopestisida, seperti anti makan (antifeedant) untuk mengendalikan hama serangga, sangat menarik perhatian para peneliti di seluruh dunia. Hal ini disebabkan karena dalam perlindungan tanaman, senyawa anti makan tidak membunuh, mengusir atau menjerat serangga hama, tetapi hanya menghambat selera makan dari serangga tersebut, sehingga tanaman pangan atau komoditi dapat terlindungi. Plutella xylostella (L) merupakan serangga hama yang penyebarannya bersifat kosmopolitan. Serangan ini dapat merusak tanaman sayuran mengakibatkan kehilangan hasil secara kuantitatif maupun kualitatif. Untuk mengatasi permasalahan tersebut, perlu dikembangkan sarana pengendalian hama yang efektif tetapi ramah lingkungan. Sulawesi Utara memiliki banyak tumbuhan yang berpotensi untuk dikembangkan sebagai sumber insektisida botani. Tanaman pangi (Pangium sp.) adalah  jenis tumbuhan yang berpotensi untuk dikembangkan dan efektif terhadap beberapa jenis serangga hama, namun pengujian dengan menggunakan ekstrak kasar dapat memberikan hasil yang beragam tergantung dari jenis ekstrak yang digunakan, faktor serangga uji dan lingkungan. Tujuan penelitian ini adalah untuk mengetahui potensi ekstrak daun pangi (Pangium sp.) sebagai anti makan terhadap P. xylostella. Metode yang digunakan adalah  metode Qin et al. (2004). Untuk mengetahui golongan senyawa aktif anti makan terhadap ekstrak kental dilakukan dengan mengambil masing-masing ekstrak untuk dibuat konsentrasi 1 % (b/v), 5 % (b/v), dan 10 % (b/v). Data dianalisa dengan analisis varians (One-way Anova). Hasil penelitian menunjukkan bahwa Ekstrak kental daun pangi mampu menghambat aktivitas makan dari larva P. xylostella.  Eugenia Volume 18  No. 3  Desember 2012 Kata Kunci : biopestisida, Pangium sp., Plutella xylostella

ABSTRACT This research aims to 1) Study the growth and yield responses of purple corn location effect of the seed source on the ear to growth and yield of, 2) Determine the right location of the seed source on the ear to get the best of growth and yield of purple corn. Research conducted at the Kebun Percobaan (KP) Pandu, Faculty of Agriculture, University of Sam Ratulangi (Unsrat) Manado from April to July 2016. The plant material used is purple corn collected in the laboratory of Plant Science, Faculty of Agriculture, Unsrat. This research is using a randomized block design by four treatments, such as: L1 (base of the ear), L2 (center of the ear), L3 (tip of the ear), and L4 (all parts of the ear). Each treatment consisted of four replicates so that there are 16 experimental units. The results showed that treatment of the seed source location on the ear gives no significant effect on all components of growth. The treatment of L4 (base of the ear) produces the highest percentage of plants grown for 14 days after planting (42.75%), treatment of L2 (center of the ear) produces highest of the plant height at 20 and 40 days after planting (6.17 cm and 45.68 cm). On purple corn yield components, the treatment provides a significant effect on the weight of ear and length of the ear, but no significant effect on the diameter of the ear, number of seed rows per ear and weight of 100 seeds. Treatment L2 (center of the ear) produces the highest yields on the weight of the ear (36.90 g), length of the ear (10.49 cm), diameter of the ear (2.92 cm), the number of seed rows per ear (7.55 lines) and weight of 100 seeds (24.56 g).
