Sugarcane plant (Saccharum officinarum) is the main raw material for the manufacture of sugar. Development of sugar production can improve the economic value, and also the provision of employment for the community. In sugarcane plants there are some pests that can damage the sugar cane, one of which is a sugarcane stem borer. It can reduce the quality and quantity of sugarcane, causing a considerable loss. To overcome such a thing, there is a need for some treatment to reduce pest attack, for example by spraying vegetable pesticide the tobacco liquid smoke. The aim of the study was to determine the influence of tobacco liquid smoke to attack on sugar cane and sugar cane crops. Research was conducted in the Balai Penelitian Tanaman Pemanis dan Serat (BALITTAS), over a period of approximately 4 months. This research was implemented using Rancangan Acak Kelompok (RAK) with 7 treatment and frequent 3 times. The treatment used is the tobacco liquid smoke with concentrations of 10 cc, 8 c...

One of the insects that cause a lot of damage are termites. Forms of damage that can be caused by termites include damage to building components that made of wood and the contents of the building in the form of furniture, books, cloth, and even securities. One example of a termite species that is dangerous as a pest is Coptotermes curvignathus. Mountain soursop seeds have bioactive compounds that are very cytotoxic, so they have potential as insecticides. This research Used a Completely Randomized Design (CRD) consisting of controls and 5 treatments (P1) 20%, (P2) 40%, (P3) 60%, (P4) 80% (P5) 100% mountain soursop seed extract. The parameters observed were retention, termite mortality, and weight reduction in the test sample. Mountain soursop seed extract is effective as an insecticide against subterranean termites. The concentration of mountain soursop seed extract 40% (P2) causes termite mortality of 100% and a decrease in sample weight by 0.43%. Mountain soursop seed extract has ...

Effect of gamma irradiation [60Co] against Bactrocera carambolae Drew & Hancock in vitro and in vivo. Bactrocera carambolae Drew & Hancock is one of the most important pests on guava fruit. According to a quarantine regulation in export-import commodities, irradiation treatment is a suitable methods for eradicating infested organism, which is relatively safe for the environment. The aim of this research was to determine mortality doses and an effective dose of [60Co] gamma ray irradiation for the eradication purpose, and its implication on the survival of fruit fly B. carambolae. Two irradiation methods of in vitro dan in vivo were carried out, by exposing egg and 3rd instar larvae of B. carambolae obtained from the laboratory reared insect. Eleven doses of gamma ray irradiation of 0, 30, 50, 75, 100, 125, 150, 175, 200, 300, 450, and 600 Gy were applied, respectively. The level of 99% fruit fly mortality was estimated by the value of LD99 using probit analysis and the number of lar...
Colorectal cancer is one of the five type of highest insiden in Indonesia. One of development cancer therapeutics directed to combination of chemotherapeutic agent and chemopreventive compounds. One approach to finding a chemopreventive compounds is through the exploration of natural ingredient especialy herbs. Flavonoids is group of compounds from plants that have been widely studied as anti-cancer activity. Leave of pigeonpea (Cajanus cajan) is, kind of Legumes plants rich in flavonoids among others cajanol, quercetin, luteolin, apigenin formonentin, vitexin, orientin, biochanin A, pinostrobin, dan isorhamnetin. This study aims to determine the content of chemical compounds in the methanol extract of leave pigeon pea that has anticancer activity using WiDr colorectal cancer cells with MTT (3-(4, 5dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide) method, followed by flowcytometry test. The result of the cytotoxicity test of methanol extract of pigeonpea leaves have IC 50 of 307 ug/ml and with flowcytometry method showed necrosis WiDr cell.

The outbreak of Pestalotiopsis leaf fall disease has become a major obstacle in rubber production. The disease symptoms is yellowing on bottom leaves and decline in latex production. The control of Pestalotiopsis sp. fungus has not been widely reported, the use of liquid smoke is considered as an alternative. This study aimed to determine the efficacy of coconut shell liquid smoke and to determine the lethal concentration 50% against Pestalotiopsis sp. The research was conducted at the Disease Laboratory, Tanjungpura University-Pontianak. The efficacy of liquid smoke was tested using the food poisoning method. Different concentrations of liquid smoke were applied, including 0%, 0.2%, 0.4%, 0.8%, 1.2%, and 1.6% and repeated ten times. The incubation period for fungal growth was seven days after inoculation and the data inhibition of fungal growth analyze by Probit analysis. The results showed that liquid smoke inhibited the growth of the fungal mycelium starting at a concentration of 0.2%, reaching 20% inhibition, and increasing to 89.38% inhibition at a concentration of 1.6%. The relationship between the inhibitory effect of liquid smoke and its concentration followed regression equation, y = 2.9204x-6.6156, with a determination coefficient of 83% and LC50 was estimated to be 1.3%.
