Abstract

Cultivation plants are inseparable from disease, this disease is caused by pathogens that can damage plant physiology processes. these pathogens can be either bacteria or fungi. Fusarium wilt is caused by fusarium oxysporum, in tomatoes this disease is caused by fusarium oxysporum f. sp lycopersici. This disease can cause huge losses to farmers. The use of synthetic fungicides has been widely used to control diseases caused by fusarium oxysporum but has a major adverse effect on the environment, therefore it is necessary to have an environmentally friendly biological fungicide in controlling the disease. This study aims to examine the effectiveness of natural fungicides obtained from cocoa pods. In this study 6 treatments were used, P0 (control of healthy plants without treatment), P1 (control of sick plants treated F. oxysporum), P2 (treatment of 2% cocoa pods extract + treatment of F. oxysporum ) P3 (treatment of cocoa pods extract 5 % + treatment of F. oxysporum ), P4 (treatment of 8% cocoa pods extract + treatment of F. oxysporum) P5 (treatment of benomyl + treatment F. oxysporum ) The results showed that vegetable fungicides from cocoa pods extract were able to inhibit fusarium wilt. Each treatment has the same effect on the maximum height of tomato plants, number of fruits and weight of fruit. The highest plant height, number of leaves and highest fruit weight was at 8% extract treatment and the lowest was 2% extract treatmen.

Abstract

This research was to determine the differences composition of chemical compounds the ethanol and acetone extract from cocoa pod husks based on qualitativephytochemical analysis and gas chromatography-mass spectrometry (GC-MS) analysis.Cocoa pod husk extraction was carried out by maceration method using 70% ethanol and acetone:water (7:3) as solvents. The yield results obtained showed that the cocoa pod husk extract that extracted by acetone had a higher yield than the ethanol solvent. In the qualitative phytochemical test using color reagents was found that ethanolic extract of cocoa pod husks contained flavonoids and phenols, while the acetone extract contain tannins, flavonoids, and phenols. The GC-MS test of ethanol extract of cocoa pod husks had identified 5 main compounds that classified to fatty acid and lactone compounds, while acetone extracthad also identified 5 main compounds that classified to glycerol, ester, disaccharide, phthalic ester, and ascorbic acid compounds.

Abstract

This research aims to describe the problemsolvingskills of SMA Negeri 1 Tinambungstudents in biology subjects. The kind of research used is descriptive research with survey method using simple random sampling technique. The research subjects in this study were students of class XI MIA which consisted of 5 classes and each class was represented by 11 people, so the research subjects amounted to 55 respondent. Data collection in this study used problem solving skills test questions in the form of essays and structured interviews with biology subject teachers, lesson plan document which were intended to serve as additional information on research results. Based on the test results, the problem solving skills of students are in the less category with the percentage of understand problem 42.27%, plan completion 56.36%, solve the problem 33.18%, review procces and results 53.18%. Based on these data, it can be concluded that the problem solving skills of class XI SMA Negeri 1 Tinambung is still not enough. Thus, it is necessary to apply learning that it can improveproblem solving skillsKeywords :, ,

Abstract

This study aims to determine the damage to lung morphology in mice (Mus musculus) by administering various strong acids by inhalation. The string acids used in this study are HCl 30%, H2SO4 50%, and HNO3 50%). The subjects of the study were 2-month old mice which were divided into 4 treatment groups consisting of 2 mice per group. There are 4 gorups of mice; a control group, a treatment group with 37% hydrochloric acid (HCl), a group with with sulfuric acid (H2SO4) 50% treatment, and a group with nitric acid (HNO3) 50% treatment. Strong acids are given simultaneously with standard feed and drinking water ad libitium. Tthe mice (Mus musculus) were euthanized 10 days post treatment and surgery was performed to observe lung morphology consisting of color, weight, and shape. The study showed that the administration of strong acid damaged the lung morphology of mice and the agent causing most severe damage of lungs was the 50% nitric acid (HNO3).

Abstract

Fusarium oxysporumis one of the fungi that causes soil-borne diseases that are harmful to plants. So it is necessary to inhibit the growth of Fusarium oxysporum by endophytic fungi from karst plants by isolating, antagonism testing by looking at the presentation of inhibition and then conducting microscopic identification. The highest inhibition was found in isolate 4E.B (strong) 58% which was the best isolate in inhibiting the growth of Fusarium oxysporum, while other isolates such as 1E.A, 2A.D and 4B.D had (moderate) inhibition because they were above 30%. While isolates 3A.A and 3C.D were categorized as low (weak) against Fusarium oxysporum with inhibition values of less than 30%. The microscopic characteristics are 1E.A has septate hyphae, transparent, cylindrical and green conidia shape and color. 2A.D has a cylindrical shape and green conidia color, 3A.A is elongated and transparent, 3C.D is chain-like and green, 4B.D has a septal and gray hyphae shape and round conidia shape and gray color, while 4E.B conidia are round and green
