The aim of the study was to evaluate the effectiveness of the interaction between extract concentration and leaf condition of Terminalia catappa L. extracted from Asystasia gangetica. The study was conducted using a completely randomized design using two factors. The first factor was the condition of the extracted leaves, which were fresh, newly fallen and dried leaves. The second factor was the extract concentrations, which were 50, 75 and 100%. The parameters were the time of germination, the height of the plant, the number of leaves, the length of the root and the weight of the grass. The results of the experiment showed that there was an interaction between the extract concentration and the state of the extracted Terminalia catappa Leaf with all the observed parameters. In general, growth retardation increased with increasing extract concentration. Fungicidal potency was shown by the extract obtained from fresh leaves, followed by the extract from newly fallen leaves and the least from dried leaves.

(Lepidoptera: Plutellidae), and its primary parasitoid, Diadegma insulare Cress. (Hymenoptera: Ichneumonidae), was investigated using laboratory colonies of the insects. The differential response of third-instar diamondback moth, parasitized and unparasitized, to B. thuringiensis (Bt), and the ability of D. insulare to oviposit in Bt-stressed hosts were determined. No significant difference (P > 0.05) was found between the mean mortality of parasitized and unparasitized larvae at each of three concentrations (154, 334, and 2,237 IU/ml) of Bt endotoxin. The three concentrations were equivalent to the LC30, LC50, and LC90 of Bt potency based on preliminary tests. Parallel line assay analysis, however, revealed that the linear dose-response regressions of parasitized and unparasitized larvae were highly significant (P = 0.0001). The LC50s of parasitized versus unparasitized larvae were 373 and 175 IU/ml Bt endotoxin, respectively, indicating that parasitized larvae were less susceptible to Bt. Female D. insulare oviposited in Bt-stressed hosts. The percentage of D. insulare females emerging from Bt-treated larvae (41.4%) was not significantly different from that of untreated larvae (32.0%).

Termites' preferences and potential for harm vary depending on the species. Surveys related to termite species, estimates of damage that occurred, as well as preferences of plants and woody trees attacked in the Riau Islamic University Area were carried out as an initial step to avoid the impact of a greater termite attack. The survey results showed that termites were found in 9 of the 25 plots observed, namely Fisipol (3), Law (3), PKM Building (1), FKIP B (1), Mosque (1), Agriculture (3), Experimental Gardens (2), Student Dormitory (14), and Postgraduate (4). The types of termites that attack the Riau Islamic University area were obtained as many as four different termite species, namely Microcerotermes sp. (Family: Termitidae), Macrotermes sp. (Family: Termitidae), Schedorhinotermes sp (Family: Rhinotermitidae), and Coptotermes curvignathus (Family: Rhinotermitidae). Captotermes is one of the main pests in the Riau Islamic University area because it has been known to attack several plants for a long time. Laboratory tests using the fungus Metarhizium anisopliae showed the potential to cause mortality in termites at a spore density of 1.65 x 108 with a spore viability of 82.8%, resulting in a death time of 1.65 x 108. The best was 1.50 days and the mortality percentage was 99.17%. The spore density of Metarhizium anisopliae added with 10% zeolite was 3.5 x 107 with 90.3% spore viability (M2) resulting in a death time of 2.50 days and a mortality percentage of 75. .12%. Meanwhile, without treatment, the time of death was 5.25 days and the mortality percentage was 20.00%.

Therefore, it is necessary to modify the environmental conditions with applying mulch, such as plastic mulch or organic mulch. In addition, increased production can be done by fertilizing potassium nitrate (KNO3) which is more practical to use because it has two nutrient contents, namely potassium and nitrogen. The purpose of this study was to determine the effect of the interaction between mulch and potassium nitrate (KNO3) on the growth and production of tomato (Lycopersicum esculentum Mill.). This study used a completely randomized design (CRD) with two factorials. The first factor was the type of mulch which consists of 4 levels of treatment, which are without mulch, black silver plastic mulch, rice straw mulch, reed mulch. The second factor was the concentration of potassium nitrate (KNO3) which consists of 4 levels of treatment, namely 0, 3, 6, 9 g / l. Each treatment was repeated 3 times, in order to obtain 48 experimental units. The results showed that the interaction effect of the type of mulch and potassium nitrate (KNO3) was significant on the parameters of plant height, harvest age, number of fruits per plant, fruit weight per plant, fruit weight per fruit, and number of residual fruits. The best treatment combination was the use of rice straw mulch and a concentration of 9 g/l KNO3 fertilizer.

The aim of the study was to evaluate the effectiveness of the interaction between extract concentration and leaf condition of Terminalia catappa L. extracted from Asystasia gangetica. The study was conducted using a completely randomized design using two factors. The first factor was the condition of the extracted leaves, which were fresh, newly fallen and dried leaves. The second factor was the extract concentrations, which were 50, 75 and 100%. The parameters were the time of germination, the height of the plant, the number of leaves, the length of the root and the weight of the grass. The results of the experiment showed that there was an interaction between the extract concentration and the state of the extracted Terminalia catappa Leaf with all the observed parameters. In general, growth retardation increased with increasing extract concentration. Fungicidal potency was shown by the extract obtained from fresh leaves, followed by the extract from newly fallen leaves and the least from dried leaves.

(Lepidoptera: Plutellidae), and its primary parasitoid, Diadegma insulare Cress. (Hymenoptera: Ichneumonidae), was investigated using laboratory colonies of the insects. The differential response of third-instar diamondback moth, parasitized and unparasitized, to B. thuringiensis (Bt), and the ability of D. insulare to oviposit in Bt-stressed hosts were determined. No significant difference (P > 0.05) was found between the mean mortality of parasitized and unparasitized larvae at each of three concentrations (154, 334, and 2,237 IU/ml) of Bt endotoxin. The three concentrations were equivalent to the LC30, LC50, and LC90 of Bt potency based on preliminary tests. Parallel line assay analysis, however, revealed that the linear dose-response regressions of parasitized and unparasitized larvae were highly significant (P = 0.0001). The LC50s of parasitized versus unparasitized larvae were 373 and 175 IU/ml Bt endotoxin, respectively, indicating that parasitized larvae were less susceptible to Bt. Female D. insulare oviposited in Bt-stressed hosts. The percentage of D. insulare females emerging from Bt-treated larvae (41.4%) was not significantly different from that of untreated larvae (32.0%).

Termites' preferences and potential for harm vary depending on the species. Surveys related to termite species, estimates of damage that occurred, as well as preferences of plants and woody trees attacked in the Riau Islamic University Area were carried out as an initial step to avoid the impact of a greater termite attack. The survey results showed that termites were found in 9 of the 25 plots observed, namely Fisipol (3), Law (3), PKM Building (1), FKIP B (1), Mosque (1), Agriculture (3), Experimental Gardens (2), Student Dormitory (14), and Postgraduate (4). The types of termites that attack the Riau Islamic University area were obtained as many as four different termite species, namely Microcerotermes sp. (Family: Termitidae), Macrotermes sp. (Family: Termitidae), Schedorhinotermes sp (Family: Rhinotermitidae), and Coptotermes curvignathus (Family: Rhinotermitidae). Captotermes is one of the main pests in the Riau Islamic University area because it has been known to attack several plants for a long time. Laboratory tests using the fungus Metarhizium anisopliae showed the potential to cause mortality in termites at a spore density of 1.65 x 108 with a spore viability of 82.8%, resulting in a death time of 1.65 x 108. The best was 1.50 days and the mortality percentage was 99.17%. The spore density of Metarhizium anisopliae added with 10% zeolite was 3.5 x 107 with 90.3% spore viability (M2) resulting in a death time of 2.50 days and a mortality percentage of 75. .12%. Meanwhile, without treatment, the time of death was 5.25 days and the mortality percentage was 20.00%.

Therefore, it is necessary to modify the environmental conditions with applying mulch, such as plastic mulch or organic mulch. In addition, increased production can be done by fertilizing potassium nitrate (KNO3) which is more practical to use because it has two nutrient contents, namely potassium and nitrogen. The purpose of this study was to determine the effect of the interaction between mulch and potassium nitrate (KNO3) on the growth and production of tomato (Lycopersicum esculentum Mill.). This study used a completely randomized design (CRD) with two factorials. The first factor was the type of mulch which consists of 4 levels of treatment, which are without mulch, black silver plastic mulch, rice straw mulch, reed mulch. The second factor was the concentration of potassium nitrate (KNO3) which consists of 4 levels of treatment, namely 0, 3, 6, 9 g / l. Each treatment was repeated 3 times, in order to obtain 48 experimental units. The results showed that the interaction effect of the type of mulch and potassium nitrate (KNO3) was significant on the parameters of plant height, harvest age, number of fruits per plant, fruit weight per plant, fruit weight per fruit, and number of residual fruits. The best treatment combination was the use of rice straw mulch and a concentration of 9 g/l KNO3 fertilizer.

However, conventional insecticides are not appropriate to be applied against pests of stored food materials, such as peanut due to the residue issue. Method of fumigation which negate the residue issue is also not feasible for public practice due to the hazard potency. This consideration necessitates the exploration of safe insecticide material such as neem leaf and piper leaf using suitable method. Paper presented here is a literature review design to analyze related to the important pest of stored peanut, content and effication of neem and piper leaves, and the efficiency of muslin-cloth pad containing the botanicals. Based on the neem characteristics which is anteefedant and the characteristics of piper leaf which is volatile. It can be concluded that botanicals from these two species prepared in muslin-cloth pad, would be able to control pest of stor...
