Exploration of allelochemicals with phytotoxic effects is intended to minimize a current dependency on synthetic herbicides in weed management. Several allelochemicals from the tropical tree <em>Cerbera manghas</em> (sea mango) have been reported as termiticides and bactericides. The present study investigated possible phytotoxic effects of <em>C. manghas</em> leaf extracts under laboratory conditions. Four monocots: barnyard grass (<em>Echinochloa crus-galli</em>), foxtail fescue (<em>Vulpia myuros</em>), Italian ryegrass (<em>Lolium multiflorum</em>), and timothy (<em>Phleum pratense</em>) and four dicots: alfalfa (<em>Medicago sativa</em>), garden cress (<em>Lepidium sativum</em>), lettuce (<em>Lactuca sativa</em>), and rapeseed (<em>Brassica napus</em>) were used as test species. Elongation of both shoots and roots of seedlings was measured to assess any phytotoxic effects. The results showed that the sensitivities of shoots and roots were different between the test species, and the inhibition of seedling elongation significantly increased with increasing concentration of leaf extracts of <em>C. manghas</em> for all the test species. The IC<sub>50</sub> (50% inhibitory concentration) values showed that 8.50–32.30 and 4.26–34.67 mg dry weight equivalent extract mL<sup>−1</sup> of <em>C. manghas</em> inhibited seedling elongation by 50%, for shoots and roots respectively. Isolation and identification of the phytotoxic substances from <em>C. manghas</em> are suggested for future investigation.

<p>Dengue Hemorrhagic Fever (DHF) or Dengue Hemorrhagic Fever (DHF) is a disease caused by a virus which is very dangerous because it can cause the patient to die within a few days. Bandar Lampung city itself is a dengue endemic area. According to data from the Lampung Provincial Health Office, in 2015, from 15 there were 2,996 deaths in 31 people. The study aimed to knowing the effectiveness of bintaro seed extract (Cerbera manghas) as larvacide in III instars Aedes aegypti larvacides experimental research with post test only control group design. The sampling method was purposive sampling. Independent variables were bintaro seed extract (dose and time), the dependent variable was Aedes aegypti larvAedes The results showed that from 5 types of doses with 5 repetitions, the death result of Aedes aegypti larvae with a dose of 0% had no mortality, a dose of 0.1% with an average of 12.55, a dose of 0.5% with an average of 15.15 , 1% dose with an average of 18.20, a dose of 1.5% with an average of 22.15, and a dose of 2% with an average of 25. At the time of contact, the death result of the larvae was found with an average 6-hour contact time. an average of 8.70, 12 hours with an average of 14.13, 24 hours with an average of 18.37 and 48 hours with an average of 20.83. According to the results of statistical tests, the most effective effect of bintaro seed extract dosage is at a dose of 1.5% and contact time of 6 hours.<strong></strong></p>

Charcoal briquettes are smokeless fuels which are a type of solid fuel whose fly substance is made low enough so that the smoke generated on its utilization will not interfere with health. In this study charcoal briquettes were made from bintaro shell waste and betung bamboo using tapioca flour adhesives. This study aims to obtain the best quality sub-bituminous coal briquettes and coal briquettes. In this study the carbonization temperature used was 400ᵒC and the composition of raw materials for bintaro shells and betung bamboo was 50:50, the composition of raw materials for sub-bituminous coal and straw 90:10. The method used in this research is experiment or experimental method, with fuel value collection using ASTM D5865-03 standard. The results obtained from this study are for charcoal briquettes with 4000C carbonization temperature Inherent Moisture value of 1.91%, ash 2.29%, volatile matter 23.79%, fixed carbon 72.01% and calorific value 5878.7 kal / gr, and for coal briquettes obtained value Inherent Moisture 0.52%, ash 4.42%, volatile matter 17.98%, fixed carbon 77.08% and calorific value 7152.6 kal / gr. The fuel value of coal briquettes is greater than that of charcoal briquettes, but the combustion value of charcoal briquettes includes a good calorific value as an alternative energy source, and is in accordance with the SNI standard of 5000 kal / gr, even close to the Japanese standard 6000 cal / gr. Keywords: Bintaro, briquette, calorific value
