An experiment on the effectiveness of biopesticide made of ramayana (Cassia spectabilis) and tobacco leaves (Nicotiana tabacum) it called as Casnic, on Hypothenemus hampeiand Planococcus citriand its effect on the arthropods population fauna in coffee plantation had been conducted in Pest Laboratory of Indonesian Coffee and Cocoa Researh Institute and Bangelan Plantation in Malang. The treatment consisted of three level concentrations of botanical pesticide(15 ml, 30 ml, and 60 ml/lof water), Beauveria bassiana(at a dose 100 g spore per ha), metidation spraying (2 ml formulation per litre of water) and two control treatments (with and without soap). The field experiment was arranged in randomized complete block design (RCBD) with four replications. The results showed that botanical pesticide at the concentration of 30.0 ml stock solution per litre of water and applied four times with monthly interval was effective in controlling coffee berry borer (Hypothenemus hampei) and coffee mealy bug (Planococcus citri). The effectiveness was not significantly different compared to metidation and Beauveria bassianaat the dose of 0.8 l and 100 g formulation per ha per application. Application of the botanical pesticide did not show negative effect on the usefull predatory insects and other arthropods population in coffee ecosystem. Key words : Botanical pesticide, Cassia spectabilis, Nicotiana tabacum, Coffee, Hypothenemus hampei, Planococcus citri, Arthropods.

Maize is an important commodity in Indonesia and is vulnerable to maize weevil (Sitophilus zeamais) during storage which can cause a 100% yield loss. Chasew Nut Shell Liquid (CNSL) is a botanical pesticide able to control S. zeamais. Increasing CNSL efficiency and effectiveness requires additional adjuvants, such as solvents and dyes. Natural dyes addition is intended to provide seed markers. This study aimed to determine the best CNSL and natural dye formulation to control maize weevil and maintain maize seeds quality during storage. The research was conducted from August to October 2018 at the Agronomy Laboratory, Faculty of Agroindustry, Yogyakarta Mercu Buana University. The research was a single factor consisted of seven treatments with four replications arranged in a completely randomized design (CRD). Treatments were combinations of CNSL concentrations with the addition of natural dyes from suji leaf and teak leaves with one untreated control. The results of the research showed that CNSL as a seed treatment botanical pesticide could cause mortality and suppress S. zeamais populations and maintain the quality of maize seeds during storage for 12 weeks. Treatments with 20% CNSL formulation concentration and the addition of natural dyes both leaf pleomele or teak leaves could cause higher mortality and push down more populations and also could better maintain seed quality than 10 and 0% CNSL formulation concentrations.

ABSTRAKKemiri sunan (Reutealis trisperma (Blanco) Airy Shaw) dikenal sebagai tumbuhan yang berperan sebagai pestisida nabati yang belum banyak diketahui keampuhannya, sehingga perlu dilakukan pengujian untuk memperoleh informasi tentang keampuhan dari tumbuhan ini. Pengujian efektivitasnya dilakukan terhadap larva Crocidolomia binotalis Zell. penyebab kerusakan pada tanaman sawi. Percobaan dilaksanakan di Laboratorium Vertebrata, Departemen Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Padjadjaran, Jatinangor, berlangsung dari Maret sampai Mei 2019. Percobaan menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 5 ulangan. Perlakuan meliputi minyak kemiri sunan dengan konsentrasi 10%, 5%, 2.5%, 1.25% dan kontrol. Hasil penelitian menunjukkan minyak kemiri sunan berpengaruh terhadap larva Crocidolomia binotalis. Konsentrasi 10% dapat mengakibatkan mortalitas paling tinggi sebesar 100% pada 7 HSA. Selain toksik, minyak kemiri sunan juga dapat memperpanjang lama perkembangan larva, menghambat aktivitas makan (antifeedant), serta menurunkan berat kering larva dibandingkan dengan kontrol. Minyak kemiri sunan berpotensi sebagai alternatif pengendali hama yang ramah lingkungan karena dapat berperan sebagai pestisida nabatiKata kunci: Kemiri sunan, Crocidolomia binotalis, Pestisida nabatiABSTRACTReutealis trisperma (Blanco) Airy Shaw is know as a plant that acts as a vegetable pesticide that is not yet widely known for its efficacy, so testing is needed to obtain information about the efficacy of this plant. Effectiveness testing is carried out on Crocidolomia binotalis Zell. larvae causing damage to oil palm plants. The experiment was carried out in the vertebrate laboratory, the deparment of pest and plant diseases, the faculty of agriculture, the university Padjadjaran, taking place from March-May 2019. The experiment used the randomized design complete with 5 treatments and 5 replication. The treatments included oil Reutealis trisperma (Blanco) Airy Shaw with a concentration 10%, 5%, 2.5%, 1.25% and control. The result hazelnut oil affected the larva Crocidolomia binotalis Zell. 10% concentration can cause the highest mortality of 100% at 7 HAS. In addition to toxic, hazelnut oil prolong the development of larvae, inhibit feeding activity, and reduce the dry weight of larvae compared to controls. Hazelnut oil has potential as an alternative as an a alternative pest control that is environmentally friendly because it can act as a botanical pesticide.Keywords : Reutealis trisperma, Crocidolomia binotalis, Botanical pesticide

Research  on  the  development  of  botanical  pesticides  should  be developed  through  new  methods,  such  as  by  inhibiting the  activity  of  digestive enzymes  by  secondary  metabolites.  The  aim  of  this  study  was  to  identify some  of  potential  plants  as  a  source  of  tannin-protein  complexes  to  inhibitthe  activity  of  - amylase.  The  study  of  identification  of  potential  plants producing  the  active  ingredient  tannin-protein  complex  was  divided  into  three stages,  1)  identification  of  potential  plants  producing  tannin,  2)  isolation  of tannin-protein  complexes,  and  3)  in  vitro  test  of  tannin-protein  complexes effect  of  the  -amylase activity.  Some  of  the observed  plants  were  sidaguri  leaf (Sida rhombifolia), melinjo leaf (Gnetum gnemon), gamal leaf (Gliricidia sepium),lamtoro  leaf  (Leucaena  leucocephala) ,  betel  nut  (Areca  catechu) ,  and  crude gambier  (Uncaria  gambir) a s  a  source of  tannins  and  melinjo  seed was  used  asprotein  source.  Betel  nut  and  melinjo  seed  were  the  best  source  of  tannin-protein  complex,  tannin  content  1.77  mg  TAE/mL  with  antioxidant  activity  of  90%,the  ability  to  inhibit  the  activity  of  -amylase by  95%  with  IC 50  values  of 10 mg/mL.Key words: Tannin, protein, -amylase, botanical pesticides,Areca catechu, Gnetum gnemon.
