Abstract

Leptospirosis is an acute infectious disease in humans caused by Leptospira sp. This disease is classified as a zoonosis that usually occurs during the flood and is commonly transmitted through rat urine. Leptospirosis occurs through humans contact with animals or the environment that have been contaminated by Leptospira. There are wide spectrum clinical manifestations of leptospirosis varying from self-limited to severe disease. Leptospira commonly enters human body through conjunctiva or injured skin, food or beverage contaminated with urine’s rat containing Leptospira. This disease is very difficult to be distinguished from other diseases such as meningitis, malaria, dengue fever, hepatitis and enteric fever. Clinical symptoms of leptospirosis are nonspecific and due to the difficulties in conforming the diagnosis so that resulted to the misdiagnosis of this disease. Microbiological examination is done by Rapid Diagnostic Test, Microscopic Agglutination Test, Polymerase Chain Reaction test and others. Prevention can be done by inhibiting the entry of Leptospira to human body via implementing clean and healthy life and surrounding environment.

Abstract

Invasion of broadleved weeds cause competition with local grasses which are the main feed for herbivores. Chemical control should use selective herbicides that only kill the broadleaved weeds without harming the grass. The research was conducted in the savanna Bekol - Baluran National Park, East Java, from January 2015 until March 2015 to find the best rate of herbicide to control broadleaved weeds in the savanna and to estimate the soil residue of herbicide used. The experimental design was a randomized block with six treatments and four replications. The treatments were herbicide applications consisted of (1) the rate of triclopyr at 670 g a.i ha-1 (TA), (2) rate of triclopyr at 1340 a.i ha-1 (TB), (3) the rate of fluroxypyr at 200 g a.i ha-1 (FA), (4) rate of fluroxypir at 400 g a.i ha-1 (FB), (5) Weeding Manual (PM) and (6) Control (K).The result showed that there was a change in the composition of the vegetation after herbicide applied. The dominance of broadleaed weeds was replaced by the dominance of Brachiaria reptans and Sclerechnae punctata. The application of triclopyr at 1340 g ai ha-1 was able to reduce weed infestation to 0.48 g 0.25 m-2 compared to 12.66 g 0.25 m-2 before the herbicide application. It facilitated the growth of grasses up to 6.87 g 0.25 m-2 which was among the best of treatments applied because it has shown maximum effectieness for controlling broadleaved weeds.

Abstract

Terasi is a condiment in a variety of Indonesian cuisine. Toboali’s shrimp paste is made in the Toboali district, South Bangka. This shrimp paste is famous for being delicious and without other additives such as preservatives and coloring agent. The purpose of this study was to compare the bacteria quality of shrimp paste with different fermentation times. The salt content used in this study was 20%. Shrimp used as raw material in this study was A. japonicus and the salt used was solar salt. The results showed that the shrimp paste at 0 and 7 days of fermentation contained coliform and colifecal. After 14 days and 28 days of fermentation, the shrimp paste did not contain coliform and colifecal. All samples did not contain E.coli and Salmonella. Meanwhile, the total nonhalophilic bacteria and halophilic bacteria decreased until the end of fermentation. Lactic acid bacteria increased until 14 days fermentation and decreased until the end of fermentation. Non-halophilic bacteria was still above the permissible number for food product safety (more than 105 CFU/g) up to 21 days of fermentation. Based on the results obtained, the shrimp paste should be fermented up to 28 days of fermentation to reduce the number of coliform, colifecal and total non-halophilic bacteria.

Abstract

Fruit flies are the main pests that attack various types of fruit vegetables and fruits that can caused a damage in the quality and quantity of production. Fruit flies controlling by chemical insecticides is common to use nowadays, but excessive use of chemical insecticides has a negative impact on the health and environment. One alternative to control the fruit flies is using oleoresins of Chromolaena odorata leaf. This study aims to determine the effect of C. Odorata leaf oleoresin on increasing the mortality of fruit fly pests (Bactrocera cucurbitae). This research used an experimental method with Completely Randomized Design (CRD) which had 6 treatment levels, namely: N0 (Aquadest), N1 (Oleoresins 2%), N2 (Oleoresins 4%), N3 (Oleoresins 6%), N4 (Oleoresins 8%), N5 (Oleoresins 10%), was replicated 4 times so there were 24 experimental units. The results showed that the application of C. Odorata leaf oleoresin had no sigificant effect on mortality percentage and mortality rates, but oleoresin had the potential to increasing fruit fly mortality as concentrations increased. It is necessary to test the increasing concentration of oleoresin > 10% to control fruit fly pests.

Abstract

Malaria is a health problem that can cause death. Research based on a literature review shows that malaria is an infectious disease that causes high morbidity worldwide and is the third leading cause of death in the world. Malaria is caused by Plasmodium infection of red blood cells, Plasmodium infection can cause various symptoms in humans, especially in platelets. The purpose of this study was to find out how the effect of Plasmodium sp. infection. Against Human Platelets. This research method uses a literature review (literature review). Literature review is research by searching and mapping literature. This research was conducted using various sources, including books, journals, magazines, and articles. Based on research, Plasmodium infection can disrupt the structure and function of platelets. Almost all blood components are affected by malaria. The risk of malaria is caused by environmental factors. the mobility of malaria sufferers at school and productive age, whose activities are mostly outside the home, makes them very vulnerable to malaria, because they are more often affected than people who do a lot of activities outside the home. So it can be concluded that malaria is influenced by environmental factors. The variability and range of environmental influences on malaria mediators is enormous

Abstract

Local microorganisms (MOL) contain fermented solutions made from various local resources. MOL solution has the potential to be used as liquid organic fertilizer because it contains microorganisms that can increase plant growth. This study aims to determine the characteristics of MOL based on different sources of microorganisms obtained from food ingredients typical of Bangka Belitung, as well as to determine their effectiveness on the growth of Ipomoea reptans (L.) Poir. This experimental study used a two-factorial completely randomized design (CRD), namely the type of MOL (without giving MOL (M0), MOL made from Bangka shrimp paste (M1), MOL made from rusip (M2), and MOL made from kitchen waste (M3)) and MOL dose (0% (D0), 15% (D1), 25% (D2), and 50% (D3)). Each treatment was repeated 2 times with a total of 32 experimental units. The variables observed were the characteristics of MOL after 1 week of incubation and the effect of giving MOL on the growth of Ipomoea reptans (L.) Poir 14 days after planting (HST). Data were statistically analyzed using SPSS software version 25 using the analysis of variance (ANOVA) method and Duncan's multiple range test (DMRT) with a 95% confidence level. The results showed that all MOL treatments were successfully fermented with characteristics of sour aroma, liquid texture, produce CO2, acidic pH, and presence of bacteria and mold. The results of ANOVA showed that the factor of giving the type of MOL and the interaction both factor had a significant effect on all observation parameters. However, the MOL dose factor did not significantly affect all observation parameters. Treatment of interaction the type and dose of MOL M2D1 can increase the response of the number of leaves, plant wet weight, plant dry weight, shoot dry weight, and root dry weight of Ipomoea reptans (L.) Poirs. The teratment of M1D3 increased the height response of Ipomoea reptans (L.) Poirs.
