![]() ![]() The results showed that the development of a practicum guide for testing nutrients in goat's milk was successfully carried out and obtained a validity value of CVR=1. The type of validation used is content validity which contains 3 aspects, namely aspects of format, content, and language. There are 5 product validators consisting of 2 lecturers from the Biology Education Study Program, FKIP Tanjungpura University and 3 biology teachers from 3 high schools in Pontianak City. ![]() The research instrument used was a validation sheet in the form of a questionnaire. This type of research is research and development (R&D) that uses the first 3 stages of the 4D model (define, design, develop, and disseminate). This study aims to develop and test the feasibility of a practical guide for testing nutrients in goat's milk in Food Substances for class XI SMA. The sample used in the practicum should also be chosen carefully so as not to lead to misconception in students. Practical guide books need to be prepared to ensure a good practicum activity.

Based on the results of research and discussion we concluded that: (1) There is the effect of star fruit solution on mortality of larvae of Culex sp mosquitoes, with coefficientH=17.73>Chi-square value of7.81at α level of 0.05, 11, 3 Dapaαlevelof 0.01., (2) At a dose of4/96 ml solution starfruit is the best dosage on mortality of larvae of mosquito Culex sp., (3) the results of this studying the form of LKPS (Practical Guidelines Worksheet) can support (KI) and (KD) in the curriculum syllabus 2013.Keywords Alocasia, Colchicine, Genetic Diversity, Mutagenic. The results of the analysis are obtained as follows: (1) There is a very significant influence on the administration of a solution of fruit starfruit (Averrhoa bilimbi, L.) against Culex mosquito larvae mortality due to the α sp 0.05, at α 0.01 in Chi-square table, (2) the mortality of larvae of Culex for 24 consecutive hour sare from lowest to highest mortality percentage is P0=0%, P1=60%, P2=83.33%, 83.33% =P3, andP4=86,66%. The test was analyzed using one-way Anava non-parametric Kruskall-Wallis test. Larva l sampling and testing conducted at Flores Street No. This study uses the method of experiment, the draft design used was completely randomized design Variety (CRD) with the control (P0) and 4 treatments, namely P1: a dose of1/99 ml, P2: dose2/98 ml, P3: dose3/97 ml, and P4: a dose4/96 ml with 6 replicates each, the number of larvae 150 animals. mosquito larvae mortality, (2) determine the most appropriate dosage on mortality of larvae of mosquito Culex sp., (3 ) Compile the results of the research as a high school biology class X LKPS semester two. The purpose of this study was to determine (1) Whether or not the effect of giving a solution of fruit starfruit (Averrhoa bilimbi, L.) against Culex sp. Insect repellent made from synthetic chemicals if used excessively will cause adverse effects to humans such as respiratory disorders, digestive, and the environment. Insect repellent effective to kill mosquitoes, but that has not been come mosquito larvae will develop into mosquitoes. Larvicides used in an attempt to reduce the population of larvae in a breeding place or for termination of the chain of mosquito breeding. ![]()
