In terms of control, various natural chemical compounds derived from plants can be used. Like papaya and soursop leaves, the formulation of the problem is whether the combination of soursop leaf extract and papaya leaf extract is effective in controlling S. litura pests and what is the most effective extract concentration. This study used a completely randomized design (RBD) with 5 treatments and 5 replications. Observation variables included symptoms, morphological changes and mortality, the results were analyzed by Analysis of Variance (ANOVA) followed by the Least Significant Difference (LSD) 5% test. The initial symptoms that were seen one day after application of the combination were morphological changes in the test larvae. Such as damage to the body of the larva, change in color, then the larva's body shrinks, when touched the larvae easily fall. The highest mortality was found at the extract concentration of 20% with a mortality rate of 64.79% on the second day. The results showed that the high mortality rate was closely related to the high toxicity contained in the 20% extract concentration. It was concluded that the results of the effectiveness test of the combination of papaya leaf extract and soursop leaf extract were effective. Suggestions for the use of natural materials that are easily available can be used as an alternative to control pests that are environmentally friendly. Furthermore, it is suggested that if you want to increase mortality, you can try increasing the extract concentration.

ABSTRACT Vegetables are one of the agricultural products that are needed and this annual crop is a plant that is generally relatively little time to plant. Of the various types of vegetables, including lettuce. To get good results, both in quality and quantity for lettuce, one of the efforts that can be taken apart from the provision of Growth Regulatory Substances (ZPT). With a good ZPT, good lettuce plants will be produced both in terms of quality and quantity. One of these ZPT is Moringa leaf extract. The purpose of this study was to determine the effect of the treatment of Moringa leaf extract concentration on the growth and yield of lettuce plants and to determine the concentration of Moringa leaf extract which is best used to increase the growth and yield of lettuce plants. The study was conducted at the STIPER Experimental Garden Petra Baliem Wamena Jayawijaya Regency at an altitude of 1664 meters above sea level. The study was conducted in June to September 2017. Materials used were: Lettuce Seeds, Moringa Leaves, Polybags, Soil. The tools used are: Digital Scales, Stationery, Blenders, Strainer, Measuring Cup. The study used a Completely Randomized Design (CRD) consisting of 4 levels of concentration of Moringa leaf extract treatment and 4 replications. The level of treatment of Moringa leaf extract concentration are: K0: 0% concentration (300 ml water without Moringa leaf extract); K1: 25% concentration (75 ml of Moringa leaf extract + 225 ml of water); K2: 50% concentration (150 ml moringa leaf extract + 150 ml water); K3: 75% concentration (225 ml moringa leaf extract + 75 ml water). In this study there were 4 (four) treatments and 4 (four) replications so that there were 16 plots / units of the experiment. The results of this study are: 1) The concentration of Moringa leaf extract can affect lettuce height at 1 week, 2 weeks and 4 weeks; number of leaves of lettuce at 2 weeks, 3 weeks and 4 weeks; and fresh weight of lettuce. and 2) The best concentration of Moringa leaf extract for growth and yield of lettuce is K2 concentration (50% concentration).Keywords: concentration, moringa leaf extract, lettuce ABSTRAK Sayuran merupakan salah satu produk pertanian yang sangat dibutuhkan dan  tanaman semusim ini merupakan tanaman yang pada umumnya relatif sedikit waktu tanamnya.

The white fly explosion might be occurred on the flooded fields and lack of nitrogen fertilizer. Some control methods have to be conducted to prevent further losses. The use of biopesticide was known to be easier, cheaper and environmental friendly control methods. Therefore the aim of this experiment was determining the effect of white champa leaf extract (Plumeria acuminata) as a biopesticide on sugarcane white fly eclosion (Aleurolobus barodensis). Experiment was conducted in the laboratory, using a completely randomized design with 6 treatments of P. acuminata leaf extract concentrations, that were 0% (control), 10%, 20%, 30%, 40% and 50%, and was replicated 4 times. The results showed that P. acuminata leaf extract could be used to control sugarcane white fly. The effective leaf extract concentration was 40%. The results also proved that P. acuminata leaf extract killed the white fly pupae instead of delaying their eclosion.

 Duck eggs are one type of protein source food that is much favored by the people of Indonesia.  However, currently there are not many ways of preservation to maintain the quality of duck eggs in storage.  With preservation by immersion with noni leaf extract, it can be an alternative in maintaining the quality of duck eggs in storage for 15 days.  This is because noni leaves contain elements of chemical compounds such as amino acids, phenolic compounds, ursulic acid, alkaloids, phenols, and glycosides which are antimicrobial, antibacterial and anti-inflammatory.  This study aims to determine the effect of soaking duck eggs in noni leaf extract on the interior quality of duck eggs.  This study used a completely randomized design (CRD) with a concentration of 45% noni leaf extract with immersion time of 0, 12, 24, 36 and 48 hours with 3 replications.  To determine whether there is a difference in treatment using Duncan Multiple Range Test (DMRT) at the level of = 0.05.  The research variables are Albumen Insex, Yolk Index and Haugh Index.  Data were analyzed by SPSS.  The results of the study concluded that soaking duck eggs with noni leaf extract for 12-48 hours with an extract concentration of 45% had no significant effect on egg quality in this case the yolk index, albumen index and Haugh index.
