Abstract

Environmental damage included the limestone mining process would remove the topsoil layer, reduce fertility, reduce microbial diversity and eliminate the vegetation that growth above it. Naturally, pioneer plants could grow to replace lost plants. Pioneer plants can be used as a reference for land recovery because these plants could grow on damaged land because they are associated with Plant Growth Promoting Rhizobacteria (PGPR). In addition, the presence of pioneer plants could inhibit soil erosion due to its root ability to hold the soil from scouring water. This study aimed to determine the characteristics of the initial natural succession process, namely the pioneer post-limestone mining community. This research was conducted by purposive random sampling method at three mining locations, namely Banjaragung Village, 5 years after mine, Maibit Village, 8 years after mine, and Rengel Village, 7 years after mine. Samples were taken for each of the 10 plots of 1x1 m size. The results of this study obtained 5 types of plants with the highest INP, namely: Lamium barbatum, Chromolena odoratum, Tridax procumbens, Waltheria indica, and Digitaria sanguinalis. While the highest diversity index is in the Village of Maibit, Rengel Sub-District, Tuban Regency after 8 years post-mining, which is 2.54.

Abstract

Research on the toxicity of n-hexane extract of Albizia falcataria sawdust against Hypothenemus hampei has been conducted. The method of research was contact method. The concentrations used in the experiment were control (aquadest); 0.25%; 0.5%; 1%; 2%; and 4%. Every concentration was sprayed on the female imago. Observations were performed 120 hours after treatment. The results showed that there was an effect of the length of observation time and concentration on the mortality of H. hampei (GLM Test α= 5%). The time of observation and concentration of A. falcataria sawdust n-hexane extract has positive correlation on H. hampei mortality. Therefore, the longer the treatment time, the more H. hampei mortality is increased. The mortality of H. hampei also increased with increasing concentration given. At a concentration of 4%, extract of A. falcataria sawdust has high toxicity which causes the highest mortality (> 92%).

Abstract

Kaffir lime (Citrus hystrix DC.) is an alternative source of potential and relatively safe anticancer compounds as it contains bioactive components. Previous study has shown that the extract of kaffir lime leaves contains terpenoids and potentially as anticancer. However, the content of bioactive compounds may vary due to environmental factors. Callus culture is an alternative method of induction of bioactive compound content with a controlled environment. Previous study has succeeded in inducing callus from kaffir lime seed explants produce the ideal callus with a crumb / friable texture. Methyl jasmonate is reported to induce the production of secondary metabolite compounds. Elicitation with methyl jasmonate is one of the strategy to increase terpenoids from cultured cells Objective of this study is anlyze the using of methyl jasmonate as elicitor.to increase bioactive compounds inkaffir lime cell suspension. Callus induced from seed explants age 40 days were transferred into liquid medium for the initiation of suspension culture. Subculture is done when the age of culture reaches 21 days then measured thegrowth curve o f cell supension and concentration of sucrose in medium. After cells reached log phse in 12 days then be treated with methyl jasmonic for 8 days. The cell suspension then beextracted with ethyl acetate by maceration method. The content of bioactive compounds in the extract was anlyzed with GC-MS. Suspension of lime lime cells C. hystrix, without treatment yields fatty acid compounds. Bioactive compounds produced by suspended cell suspension after methyl jasmonate elicitation is germacrene A, myrcene, alpha-terpineol, geranyl acetate, trans-caryophyllene, delta-guaiene and several types of ester fatty acids.

Abstract

Smoking is one of the habits that can affect human health. One type of cigarette that is currently the choice is electric cigarettes. The e-cigarette content includes nicotine, propylene glycol, flavorings and glycerin. The purpose of this study was to determine the effect of exposure to e-cigarette smoke on mice strain balb / c with the parameters of the number of spermatozoa. This study used 15 male mice which were 8-10 weeks old and weighed 25-30 grams of male mice which were divided into 3 treatment groups namely control group, treatment group one and treatment group two. In the control group no exposure to cigarette smoke was carried out while in the treatment group one was exposed to cigarette smoke in mice with a dose of 0 mg nicotine and the second treatment group was exposed to e-cigarette smoke at a dose of 18 mg nicotine. Electric cigarette smoke exposure is carried out for 30 days using a suction device from a syringe. The exposure of cigarette smoke is carried out every day with successive doses of 20 times as much as 3 times with a time lag of 10 minutes (5 minutes the chamber is closed and 5 minutes of the chamber is opened). The results showed that the average number of spermatozoa in the control group was 16.816 million / ml. The average number of spermatozoa in treatment one was 10.432 million / ml and the average number of spermatozoa in treatment two was 5.234 million / ml. This shows that exposure to cigarette smoke can reduce the number of spermatozoa from the control group to the first treatment by 42.56% and the second treatment shows a decrease from the first group by 34.65%.
