Abstract

Cockroaches are the insect vectors of disease that can cause adverse effects on human health. Control cockroaches excessive use of insecticides can lead to residues in the environment and resistance cockroach. Therefore it is necessary to control the use of alternatives such as by biological agents such as entomopathogenic bacteria. This research used two isolates of entomopathogenic bacteria isolated from Spodoptera litura were found dead, Bacillus thuringiensis IPBCC collection and sterile distilled water as a control. Tests conducted by the spray and bait method at a concentration of 108. The results showed that all isolates entomopathogenic bacteria used in this research can cause mortality of cockroaches. Morphological observation and Koch's postulates test showed that the mortality of cockroaches likely caused by bacterial isolates were granted. SP4 bacterial isolates using spray method provides the highest mortality was 26.67% of the P. americana and 80% against B. germanica. Isolates of B. thuringiensis using bait influence the highest mortality of 10% of the P. americana and 6.67% against B. germanica. LT-50 was the most effective method of treatment of bacterial isolates SP4 spray against B. germanica was 2 hours 30 minutes 46 seconds.Keywords: Biological control, entomopathogenic bacterial, efficacy test

Abstract

Selama dalam masa penyimpanan, komoditi hasil panen dapat mengalami kerusakan dan susut bobot (losses) yang disebabkan oleh serangan hama. Sitophilus oryzae adalah salah satu penyebab kerugian dan kerusakan terbesar karena memiliki kemampuan cepat berkembang biak akibat suplai makanan yang melimpah, mampu berpindah bersama-sama dengan komoditas hasil panen, serta mempunyai daya adaptasi pada kondisi kering. Pengendalian secara kimiawi tidak menjadi solusi, karena masih menggunakan bahan-bahan pestisida berbahaya seperti Carbamat, Piretroid, PH3 dan Metil Bromida,yang memiliki efek karsinogenik yang memicu kanker, akibat efek residual yang tertinggal dalam komoditas pangan. Berdasarkan hal tersebut, penelitian ini menawarkan teknologi pengendalian hama gudang penyimpanan hasil panen, menggunakan pestisida alami berbasis nimba, Azadirachta indica yang efektif, aman sekaligus ramah lingkungan. Hasil bioassay menunjukkan respon yang sangat baik, dimana mortalitas 100 persen S. orizae dicapai pada konsentrasi 10 ppm produk formulasi. Uji toksisitas akut oral dan dermal juga menunjukkan produk formulasi termasuk kategori bahan tidak berbahaya (WHO, 2003).During storage, stored product commodities could be damaged and lose weight caused by pest attack. Sitophilus oryzae is one of the most dangerous stored pests because of their fast reproductive abilities due to abundant supply of foods; their moving abilities with stored commodities; and their adaptability to extremely drying condition.Chemical treatments are not solving the problems because they still contain some toxical substances like carbamate, pyretroid, methyl boric, that would lead to residual contain remains on food commodity and possess carsinogenic effect Based on that background, this research proposes new stored product pest control technology using effective and environmentally friendly biopesticide based on neem (Azadirachta indica A. Juss). Bioassay results against S. oryzae show that 100 percent mortality is achieved at 10 ppm biopesticide formulation. Both acute oral and dermal toxicity tests also show that biopesticide formulation is classified as not harmful substances (WHO, 2003).

Abstract

Karst regions in Indonesia have the uniqueness of the landscape and biodiversity. The karst is formed by the dissolution of rocks and the precipitation of mineral. In the cave, there are ornaments of stalactite and stalagmite which are formed by the process of mineral precipitation. We have isolated, screened, and identified the soil bacterium from the cave environment (Lysinibacillus macroides). These bacteria are able to precipitate calcium carbonate and can be developed as a self-healing agent concrete. We investigated the proportions and the properties of mixtures concrete containing lightweight aggregate and volcanic ash impregnated with bacteria. A comparison study was made by concrete cylinders subjected to compressive strength tests with and without the bacteria. It found that the strength of concrete with bacteria decreased by less than 10.56% for 28 days of cured specimens. This study showed that the effects of bacteria on the strength of concrete are not considerable. However, these bacteria are effective to repair in the microcrack less than 0.3 mm

Abstract

EFFECTS OF CHITOSAN COATING ON THE PHYSICAL, MECHANICAL AND ANTIMICROBIAL PROPERTIES OF FOOD PACKAGING PAPER. The coating process on food packaging paper is carried out to improve the food safety and health aspect from dangerous substance migration from food packaging into food. Chitosan has attracted interest in packaging, especially in food packaging as edible films and coatings. A paper from oil palm empty fruit bunches (OPEFB) pulp was coated with chitosan using different pulp weight (1, 1.5, 2 g) and chitosan content (0.25, 0.50, 0.75, 1 g) as parameters. The effect of chitosan as coating material on physical, mechanical, and antimicrobial properties was studied. The results showed that the density and grammage values of the paper increased after coating due to the increasing of chitosan content. The mechanical properties of the coated paper, such as tensile strength, tensile modulus and elongation, improved in line with the increase of chitosan content and pulp weight. The addition of chitosan on paper imparts antimicrobial properties against Gram-positive bacteria (Staphylococcus aureus) and Gram- negative bacteria (Escherichia coli).
