Coccus Viridis

This study was conducted to examine the effect of “keben” seed Baringtonia asiatica (L.) Kurz on mortality of flea (Coccus viridis) found in Coffea sp. Experimental methods with Complete Random Design (CRD) was used in this study. Five doses of “keben” seed extract (0.2%, 0.4%, 0.6% 0.8% and 0.0%) were used. Result of the study showed that all five concentration of “keben” extract were toxic to Coccus viridis, therefore can be used to control pest of coffe caused by Coccus viridis. Among the concentration used, it was found that concentration at 0.4% more effective than other concentrations. Consentration at 0.4% was killed 100% of Coccus viridis population in 3 days.Key words: Barringtonia asiatica, Coccus viridis, Concentration of seed extract.

Sample Extract

The purpose of this research was to compare potential biolarvasida lethal concentration from extractherba Ageratum conyzoides and leaves Saccopetalum harsfieldii to larva aegypti. This research used the experimental methods with completely random design. With two test, preliminary bioassay and real bioassay. After preliminary bioassay was done, real bioassay was done by determining 8 concentration of leaves extract Saccopetalum horsfieldii, which were: 300 ppm, 600 ppm, 1200 ppm, 2000 ppm, 3000 ppm, 3500 ppm, 5000 ppm, 6000 ppm, and 1 control. For sample extract Ageratum conyzoides were: 750 ppm, 1500 ppm, 2000 ppm, 2500 ppm, 3000 ppm, 4000 ppm, and 1 control. Each treatment was replied five times. In order to know LC 90 from leaves extract of S. horsfieldii and herbs extract of Ageratum conyzoides probit analysis was used. The result of this research indicated extract herbal Ageratum conyzoides is more toxic compare with extract Saccopetalum horsfieldii leaves, this case identified by value LC 90 Ageratum conyzoides more lower than LC 90 Saccopetalum horsfieldii.

Abstrak. Tanah suboptimal adalah tanah yang kehilangan kemampuannya untuk mendukung kegiatan fisiologis tumbuhan. Penelitian ini bertujuan untuk mendapatkan bahan amelioran dan dosis pupuk yang tepat sifat kimia tanah dan pertumbuhan padi galur sikuneng. Penelitian ini menggunakan metode eksperimen dimana perlakuan disusun dalam bentuk Rancangan Acak Kelompok pola Faktorial dan diulang sebanyak 3 kali. Faktor pertama bahan Amelioran yaitu Gipsum, Biochar dan PIM-organik dan faktor kedua dosis pupuk Urea,SP36 dan KCl. Hasil penelitian yang didapat adalah amelioran PIM-organik dapat meningkatkan pH dan pertumbuhan padi galur sikuneng sedangkan perlakuan pupuk N:P:K 225:150:150 kg ha-1 dapat meningkatkan K-dd tanah suboptimal dan pertumbuhan padi galur sikuneng, serta terdapat interaksi amelioran dan pemupukan dalam meningkatkan P-tersedia dan jumlah anakan padi tersebut.Restoration Technology and Sub-Optimal Soil Fertilization and Its Relationship with Soil Chemical Properties and Growth of Sikuneng Strain RiceAbstract. The suboptimal land is a land that has lost its ability to support plant physiological activity. The study was to find proper auditing materials and fertilizers of soil chemicals and the growth of rice strains. The study USES experimental methods where treatment is structured in random design groups factorial patterns and repeated as much as much as 3 times. The first factor of internal amelia, biochar and pim-organic and the second dose of urea, SP36 and KCl. While study result have been derived that the organic pim watch can improve pH and growth of resistant rice while the fertilizer treatment N:P:K 225:150:150 kg ha-1 of can enhance the K-dd soil of suboptimal and that there is feedback interactions and fertilization in enhancing the P-available amount of rice.

This study aimed to assess the potential of avocado seed extract as an antifungal agent and to determine the optimum concentration of avocado seed extract in inhibiting the growth of Colletotrichum. This research used laboratory- scale experimental methods. Inhibition test of extract towards Colletotrichum was carried out using poison food method using following extract concentration 20%, 40%, 60%, 80% and 100% Topsin M Wp 0.2% were used as negatif control. The result showed that avocado seed extract had a significant antifungal activity against Colletotrichum at the consentration of 40%, the effect was emerged since the 4th day of incubation which was observed by measuring fungal growth diameter

Penelitian ini menggunakan metode percobaan rancangan faktorial dalam rancangan acak lengkap dengan perlakuan metionin 3 taraf, yaitu 0 ppm (M0), 10 ppm (M10), 20 ppm (M20), dan ekstrak benih brokoli dengan 4 taraf, yaitu 0 g/l (E0), 1 g/l (E1), 2 g/l (E2), 3 g/l (E3), yang diulang sebanyak 3 kali. Variabel yang diamati terdiri dari jumlah tunas, berat basah tunas, tinggi tunas, jumlah daun, dan kandungan sulforafan. Data diuji dengan analisis sidik ragam, dilanjutkan dengan uji BNT. Hasil penelitian ini menunjukkan bahwa perlakuan metionin memberi pengaruh yang nyata untuk variabel jumlah tunas, tinggi tunas, dan jumlah daun; dan berpengaruh yang sangat nyata untuk variabel berat basah tunas dan kandungan sulforafan. Perlakuan ekstrak benih brokoli tidak memberi pengaruh yang nyata pada variabel jumlah tunas, berat basah tunas, tinggi tunas, dan jumlah daun; berpengaruh yang sangat nyata untuk variabel kandungan sulforafan. Kombinasi perlakuan metionin dan ekstrak benih brokoli berpengaruh yang nyata pada variabel jumlah tunas, berpengaruh yang sangat nyata pada variabel kandungan sulforafan, dan tidak berpengaruh yang nyata pada variabel berat basah tunas, tinggi tunas, dan jumlah daun. Kandungan sulforafan tertinggi dicapai pada kombinasi perlakuan metionin 10 ppm dengan 3 gram ekstrak benih (M10E3).This research was using factorial design in complete random design with three level methionine there was 0 ppm (M0), 10 ppm (M10), 20 ppm (M20) and four level extract brocoli seeds, was 0 g/l (E0), 1 g/l (E1), 2 g/l (E2), and 3 g/l (E3), become 12 treatment combinations with 3 replicated. The variable that was observed are the total of shoot, wet weight of shoot, the shoot length, total leave, and the sulphoraphane content. The data was examine with analyze of varians and continue with LSD (Least Significant Difference). The result of this research shown that application of methionine have significance to the total shoot, shoot length, and total leave; more significance to wet weight shoot and sulphoraphane content. Application of extract seeds was non significant to the total shoot, wet weight shoot, shoot length, an total leave; more significant to sulphoraphane content. Application combination of methionine and extract seeds of brocoli was significant to the total shoot, more significant to sulphoraphane content, and non significant to wet weight shoot, shoot length, and total leave. The high sulphoraphane amount was in the application of methionine 10 ppm and 3 g/l seed extract (M10E3).
