Abstract

Larvicidal and antifeedant activities of clove leaf oil against Spodoptera litura (F.) on Soybean. Economic losses due toinfestation by the soybean armyworm, Spodoptera litura can reach up to 100%. Some farmers often used insecticide to control thearmyworm. However, regular use of insecticide can cause several negative effects such as environmental pollution, residual toxicity,and health hazard for human. The objective of this research was to determine the larvicidal, antifeedant, and activities of cloveleaf oil (CLO) against the armyworm S. litura on soybean. The research was carried out at the plant pest control laboratory ofPoliteknik Pembangunan Pertanian Malang. Clove leaf oil was evaluated for its larvicidal and antifeedant activities against tenthird instar larvae of the armyworm. Completely randomized design was used with concentration levels of CLO as treatments.i.e. 0.4, 0.5, 0.67, 1.0, and 2.0% by volume. Profenofos 500 g L 0.1% and distilled water were include as control. Each treatment consisted of five replications. Mortality of the larvae and antifeedant activity were analyzed using analysis of variance, followed by probit analysis for calculating LC 50  and LT 50-1. The results showed that CLO at 2.0% concentration was the most effective with regard to larvicidal and antifeedant activities. The LC 50 of CLO was 0.09% with LT 24.6 hours. This study revealed that the environmentally friendly CLO can be used as an alternative to synthetic insecticide for control S. litura.

Abstract

The process of substantive patent examination which is complicated and takes a long time is one of the reasons the inventor is "reluctant" to apply for a patent on his invention. This research was conducted using the Current State Value Stream Mapping (CSVSM) method, which began with the creation of a process flow map with the cycle time of each activity. It is known that most of the activities are value added activities. However, there is 1 activity that is required but not added value, namely the activity of verifying the technical field of application documents; and 1 non-value-added activity, namely initialing the Patent Granting letter. The number of waiting/delaying incidents is a waste in the process of substantive examination of patent applications caused by: (a) employees generally do double work; and (b) the absence of SOPs in each sub-process/sub-activity in the process of substantive examination of patent applications. Proposed improvements are submitted in the Future State Value Stream Mapping (FSVSM). As a result, lead-time can be reduced to 11 days, which was originally 26 days; and Process Cycle Efficiency which was originally 19.23% increased to 45.45%
