Armyworms (Spodoptera litura) become important pests in Indoensia that eat leaves compared to other pests because they are polyfag. S. litura can reduce productivity even crop failure. Therefore, it is necessary to do research on how to control S. litura effectively and environmentally friendly. This study aims to determine the effectiveness of brotowali extract (Tinospra crispa) as a botanical insecticide and obtain the right concentration of fruit extract, young leaves, and old Brotowali leaves to control the armyworm (litura Spodopter). This study used a Non Factorial Completely Randomized Design (RAL) with 6 treatments of various doses of brotowali extract mixed with cow urine and 4 replications. The results of the study showed that the administration of Brotowali + Urine Cattle extract with high doses (30 ml / jar) was able to increase the speed of death of the armyworm.

Grayak caterpillar is insect pests that become pests of various food crops. Grayak caterpillars cause a decrease in crop productivity and even crop failure if they are not controlled. Pest control using chemical pesticides has many adverse effects on the environment. To minimize the occurrence of environmental damage, then it is used pest control using vegetable insecticides. Bintaro Leaf (Cerbera odollam Gaertn.) is potential as a vegetable insecticide. The purpose of this study was to examine the toxicity of granule from Bintaro leaf extract (C. odollam Gaertn.) on armyworms (S. litura Fab.). This research was a laboratory experimental research using Completely Randomized Design (CRD). Serial concentrations used in this study were 0% (control), 0.5%, 1%, 1.5%, 2%, and 2.5%. The results of this study showed that the granules of Bintaro leaf extract (C. odollam Gaertn.) were effective in causing mortality of armyworms (S. litura Fab.) at 1.5% concentration by 60% and included in toxic category. The value of LC50-48 hour granule from Bintaro leaf extract (C. odollam Gaertn) was 1.41%. Keywords: Spodoptera litura Fab. , Granula extract of Cerbera odollam Gaertn., Vegetable Insecticide.

Buah mahkota dewa merupakan tanaman yang berpotensi sebagai pestisida nabati yang diketahui mengandung zat aktif seperti alkaloid, tannin, flavonoid, fenol, saponin, dan minyak atsiri. Tujuan dari penelitian ini adalah untuk mengetahui konsentrasi dan lama perendaman ekstrak dari buah mahkota dewa yang efektif terhadap mortalitas keong mas (Pomacea. canaliculata). Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) pola faktorial yang terdiri dari 2 faktor. Faktor pertama adalah konsentrasi buah mahkota dewa sebanyak 5 g, 10g dan 15 g dan faktor kedua adalah lama perendaman selama 24 jam, 48 jam, dan 72 jam. Pengamatan meliputi mortalitas keong mas, penghambatan makan dan rata-rata waktu kematian. Hasil pengamatan penggunaan ekstrak buah mahkota dewa sebagai molusisida nabati dengan konsentrasi 15 g/l air dan lama perendaman 72 jam (K3L3) efektif untuk menurunkan daya hidup (motalitas) keong mas hingga mencapai 89,09% dan penghambat makan keong mas tertinggi terdapat pada kombinasi perlakuan K1L2 dengan persentase nilai 47,90%, sedangkan untuk kecepatan waktu kematian keong mas setelah dilakukan pengaplikasian menggunakan ekstrak buah mahkota dewa berkerja efektif pada perlakuan kosentrasi K3 dan lama perendaman efektif pada perlakuan L3.(Concentration Test and Submersion Time of God Crown Extract as Bio Molluscicide On Golden Snail Mortalities Pomacea canaliculata Lamarck)Abstract The golden snail is one of the main pests in rice cultivation area which has a high level of attack so that it can cause crop failure. God’s crown fruit is a plant that has the potential as a bio pesticide which is known containing chemical substances such as alkaloids, tannins, flavonoids, phenols, saponins, and essential oils. The purpose of this research was to determine the concentration and submersion time of extracts from the fruit of god crown which is effective against the mortality of golden snails (Pomacea canaliculata). Research method used was experimental method using Completely Randomized Design method (RAL) with factorial pattern consisting of 2 factors. The first factor was 5 g, 10 g and 15 g of the concentration of the god crown and the second factor were 24 hours, 48 hours and 72 hours of submersion time. The observation included golden snail mortality, feeding inhibition and the average time of mortality. The results of observations of the usage of the god crown fruit extract as bio molluscicide with a concentration of 15 g / l of water and 72 hours of submersion time (K3L3) were effective to reduce the life  (mortality) of snails to reach 89.09% and the highest snail eating inhibitors were found in the combination K1L2 treatment with a percentage value of 47.90%, while for the golden snail average time of mortality after application using fruit extract of god crown worked effectively on the treatment of K3 concentration and the submersion time is effective in L3 treatment.

<h1>Spodoptera litura F. is one of the important pests in Horticulture commodities which can cause damage 80% and up to 100%. Karamunting (Melastome malabathricum) is a wild plant that grows in Tarakan City. This plant is known to contain secondary metabolites which are thought to have the potential to control pests. This study aims to determine the potential of Karamunting extract as a botanical insecticide material to control armyworms. This study uses a completely randomized design (CRD) method with 1 treatment factor, namely the concentration of Karamunting leaf extract. Potential extracts as botanical insecticides were tested by dye method using 4 concentrations, namely 0 (control); 500; 1000; 2000; 4000; and 8000 ppm. The results showed that Karamunting leaf extract was able to control armyworm pests. Giving extracts of 8000 ppm (P5) in feed caused the highest decrease in eating activity up to 41,2%, larval mortality up to 85%, and the highest mortality rate after 7 days of observation. Decreased feeding activity and larval mortality were thought to be influenced by the presence of phenol compounds, fatty acids, terpenoids, sterols and alkaloids identified in the extract. Thus, Karamunting leaf extract has the potential to be developed as an active ingredient in botanical insecticides to control armyworm.<strong></strong></h1>

This study was conducted to determine the effect of different solvents on the antioxidant activity of gale of the wind extract and to find out the right type of solvent used to extract gale of the wind with the highest antioxidant activity using maceration method. The experimental design used in this study was a completely randomized design (CRD) with a type of solvent as a treatment. The treatment consisting of four levels, namely methanol, ethanol, acetone, isopropanol. All treatments were repeated four times so that they were obtained 16 experimental units. The data obtained were analyzed by variance and if the treatment had significant effect followed by Duncan test. The results showed that the type of solvent treatment had a very significant effect on yield, total phenol, total flavonoids, total tannin, and antioxidant activity (IC50). The results showed that acetone solvent had the best treatment which produced a yield of 22.58%, total phenol content of 188.77 mg GAE/g, total flavonoid content of 247.60 mg QE/g, total tannin content of 297.51mg TAE/g, and antioxidant activity (IC50) of 15.19 ppm.

Efforts to increase protein in Tempe can provide positive values for native Indonesian food. The amount of remaining egg white in the bread industry can be used in making soybean Tempe. Egg white which is rich in albumin has never been used in the manufacture of soybean tempeh by the producer. This research aims to determine the effect of adding raw and steamed egg whites on the protein content of soybean Tempe. This study used a Completely Randomized Design (CRD) with 3 replications. The concentrations of egg whites used in the research included 0%, 2%, 4%, 6%, 8%, and 10%. The research instrument used was the observation sheet for protein content using the Lowry method. The research data were dissolved protein content. The data analysis technique used Two Way ANOVA. The results of the research showed that there was no effect of adding raw and steamed egg whites on soybean Tempe protein content (P > 0.05). However, the addition of raw egg whites can increase the protein content of soybean Tempe, compared to steamed egg whites. The conclusion of this research is the addition of raw and steamed egg whites does not have a significant effect on the protein content of soybean Tempe. The right type of egg white flour to increase the protein content of soybean Tempe is raw egg white flour with a protein content of 15.0 per 100 grams.
