Abstract

Mikroorganisme yang dapat dimanfaatkan sebagai agens pengendalian hama secara hayati salah satunya adalah cendawan entomopatogen Metarhizium rileyi. Penambahan ekstrak biji sirsak dan umbi gadung sebagai media alternatif yang kaya akan nutrisi mampu memengaruhi pertumbuhan cendawan entomopatogen M. rileyi. Penelitian ini bertujuan untuk mendapatkan media pertumbuhan terbaik cendawan M. rileyi yang dicampur dengan ekstrak biji sirsak dan umbi gadung. Metode yang digunakan adalah metode eksperimental dan rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) faktor tunggal yang terdiri dari 7 perlakuan dan diulang 4 kali. Perlakuan tersebut antara lain Kontrol (PDA), PS1 (PDA + ekstrak biji sirsak 1 ml/l), PS3 (PDA + ekstrak biji sirsak 3 ml/l), PS5 (PDA + ekstrak biji sirsak 5 ml/l), PG1 (PDA + ekstrak umbi gadung 1 g/l), PG3 (PDA + ekstrak umbi gadung 3 g/l), PG5 (PDA + ekstrak umbi gadung 5 g/l). Hasil yang dicapai dari penelitian ini adalah penambahan ekstrak biji sirsak dan umbi gadung ke dalam media tumbuh M. rileyi memberikan pengaruh yang tidak nyata terhadap diameter koloni 21 hsi dengan rata-rata diameter koloni berkisar 8,95-9,00 cm, sedangkan hasil analisis regresi dan waktu inkubasi selama 21 hari berpengaruh nyata terhadap laju pertumbuhan koloni M. rileyi sebesar 44% hingga 77%. Hubungan laju pertumbuhan koloni M. rileyi dengan waktu inkubasi pada semua perlakuan menunjukkan nilai R2 sebesar 0,44 hingga 0,77. Media paling efektif untuk pertumbuhan cendawan M. rileyi adalah media PDA dengan ekstrak umbi gadung 1 g/l dengan diameter koloni 9,00 cm.

Abstract

S. frugiperda ialah hama invasif pada tanaman jagung Indonesia yang serangannya dapat mengganggu dan merugingan petani. Tujuan dari penelitian ini adalah untuk mendapatkan perlakuan yang tepat dan mampu meningkatkan mortalitas dan menekan serangan larva S. frugiperda. Metode yang dipakai merupakan metode eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal yang terdiri dari 8 perlakuan dengan 4 kali ulangan : K1 (Kontrol aquades) ; K2 (Kontrol insektisida deltametrin 1 ml/l) ; M1 (Ekstrak daun mimba 40 g/l) ; M2 (Ekstrak daun mimba 80 g/l) ; M3 (Ekstrak daun mimba 120 g/l) ; B1 (B. bassiana 107 konidia/ml) ; B2 (B. bassiana 108 konidia/ml) ; B3 (B. bassiana 109 konidia/ml). Pengaplikasian dilakukan secara kontak ketubuh larva S. frugiperda. Pengamatan dilakukan selama 14 hari dengan 10 larva instar 2 disetiap ulangan. Hasil penelitian ini adalah perlakuan ekstrak daun mimba mencapai mortalitas tertinggi yaitu 100% pada konsentrasi 120 g/l dengan nilai LT50 mencapai 5.18 hari, sedangkan pada perlakuan cendawan B. bassiana mortalitas tertinggi pada kerapatan 109 konidia/ml mencapai 87.5% dengan nilai LT50 7.26 hari. Dengan demikian konsentrasi ekstrak daun mimba 120 g/l dan kerapatan konidia cendawan entomopatogen B. bassiana 109 konidia/ml mampu untuk mengendalikan S. frugiperda dan menekan populasinya.

Abstract

Rice (Oryza sativa L.) is a rice-producing plant that is one of the staple foods for the world's population, especially Indonesia. One of the factors causing a decrease in rice production is pests, the main pest of rice plants is the golden snail. The golden snail pest attack occurs on rice plant seedlings, namely in the vegetative phase. The purpose of this study was to determine the effect of giving plant-based pesticides tuba root extract (Derris elliptica) on the mortality and pest intensity of the golden snail (Pomacea canaliculata L.) on rice plants (Oryza sativa L.) Inpari 32 variety. The method used was experimental (trial) using a single factor Randomized Block Design (RBD) with 6 treatments with 5 replications so there were 30 experimental units. Treatment of D. elliptica tuba root extract concentration on rice (Oryza sativa L.) treatment A (Control), B (5g/L), C (7g/L), D (9g/L), E ( 11g/L), and F (13g/L). Tuba root extract at a concentration of 13g/L is the best concentration which gives the highest mortality of 81.60% with the lowest attack intensity value of 29.84%. The LC50 value of the tuba root extract on the golden snail was 2.64g/L, the minimum value was 0.37g/L and the maximum was 4.164 g/L. LT50 takes a minimum of 1 day and a maximum of 9 days with an average time of 6-5 days. The results of calculating the correlation between mortality and the intensity of golden snail attacks on tall rice plants are -0.60. Administration of tuba root extract of D. eliptica was effective against the mortality of the golden snail P. canaliculata and the intensity of the attack by the golden snail P. canaliculata on rice (Oryza sativa L.).

Abstract

The brown planthopper is an important pest in rice cultivation which acts as a vector for viruses that cause grass stunt and hollow stunt disease which can cause rice plants to die or reduce production to the detriment of farmers. This study aimed to obtain a pest control technique capable of suppressing the population and intensity of brown planthopper attacks on rice plants. This study is an experimental study using single-factor Randomized Block Design (RBD) with 4 treatments and 6 replications: C (Control); CC (Combination Control); BC (Biointensive Control); SC (Synthetic Control). The analysis results obtained showed that the SC treatment gave the lowest attack intensity value of 0.00% - 28.67% with a total population of 0 - 89 individuals followed by CC (1.33% - 44.67%) with a total population of 2-114 individuals, BC (2.00%-46%) with a total population of 3 - 103 individuals, and C (2.00% -45.33%) with a total population of 3 - 102 individuals. Synthetic control can be recommended as an alternative pest control technique in reducing the intensity of brown planthopper attacks.

Abstract

Tribolium castaneum is one of stored pests with vast host against stored commodites. The purpose of this research is to know the survivability of T. castaneum and weight loss on rice and corn in the shape of whole grain, broken grain, and flour. This research used single factor Completely Randomized Design (CRD) consisting of 7 treatments with 4 replications: A (control), B (whole grain of rice), C (broken grain of rice), D (rice flour), E (whole grain of corn), F (broken grain of corn). G (corn flour). The observed variables were temperature and humidity, adult mortality, and feed weight loss. The results showed the differences of feed did not give significant effect on T. castaneum mortality but has siginificant effect on feed weight loss. Corn flour has the most weight loss by 8,50grams. This conclude that T. castaneum has high comsumption activity on corn flour.
