Abstract

Disability is one of the most attention-catching infections (neglected diseases) which didn’t cause a lot of casualties and not a sudden outbreak but it can result in a slow death by slowly roasting the body’s healthy organs until it causes permanent and lowers child intelligence. This research was to compare the prevalence of worm infection of class Soil-Transmitted Helminths on elementary school students or madrasah ibtidaiyah students in the village Abian Tubuh Baru sub-district Sandubaya in 2008 and checking out the number of cases of worm infections according to this type of worm. The methods of research used in this study is observational descriptive methods and microscopic methods to use a microscope to identify a type of worm from stool sample drawn from students on elementary school/madrasah ibtidaiyah in Abian Tubuh Baru village. The result of that feces examination indicates that there are three kinds of worms are ringworm (Ascaris lumbricoides), whipworm (Tricuris trichiura), and hookworm (Ancylostoma duodenale dan Necator americanus). The most numerous types of worms found are these Ascaris lumbricoides as big as 75,67%.

Abstract

Fusarium sp is a fungal pathogen that can infect plants with a wide host range. Fusarium question is a type of pathogen from a group of fungi that has a high level of virulence so that it can cause high damage to plants. Biological control of soil-borne diseases by utilizing extracts from plants as an alternative barrier to avoid the use of synthetic chemicals. Plants used as control or inhibitors of the growth of the fungus Fusarium sp., have compounds in the form of triterpenoids, flavonoids, tannins, essential oils, and allelopathic compounds that are released to inhibit the growth of pathogens. This research is descriptive using the literature study method to find out the potential of plant extracts that have inhibitory power on the growth of the fungus Fusarium sp. The results of the potential study of this plant extract showed that the ethanolic extract of Clitoria ternatea L. had an effect on inhibiting the growth of the fungus Fusarium sp.

Abstract

Dendrobium Sp is one type of orchid plant with the most popular species both among cultivators and entrepreneurs of orchid growers. Dendrobium Sp has flowers with basic colors that have been found, namely white, purple, red, yellow, blue, brown, and a combination of these basic colors. This research was carried out by adding a supplement drink to the basic media which showed good orchid growth, using the M-150 supplement with a concentration of 25 ml added to Vacin and Went media which gave good results on rooted palntlets and number of roots. This study used a completely randomized design (CRD) with 5 treatments, the treatments were repeated 5 times so that there were 20 treatment bottles (each bottle contains one plant). Observational data were analyzed using the Analysis of Variance at the 5% level

Abstract

This study aims to improve student learning activities and achievement by applying Bruner's learning theory to the circle material. This type of research is classroom action research which is carried out in two cycles. Each cycle consists of stages of planning, implementing actions, observing, evaluating, and reflecting. The subjects of this study were students of class VIII-3 semester II of SMP Negeri 1 Batukliang, totaling 22 people. Based on the results of the evaluation of cycle I and cycle II, the average score of student learning activities was 4.4; 4.45; which has the category of activity, and very active. The average ability of teachers to manage to learn for each meeting is 4.08 in categories; 4.17; 4.64; and 4.75 in the very high category. While the average score of student evaluation results, in the first and second cycles, were 69.55 and 91.14, respectively. In addition, the calculation of the N-Gain of student learning is categorized as high with an n-gain value of 0.71. In addition, individual and classical completeness has been achieved. Thus, the application of Bruner's learning theory can increase student activity and achievement in class VIII-3 semester II of SMP Negeri 1 Batuliang on the circle material

Abstract

This study aims to improve the activity and learning achievement of students of class VII F SMP Negeri 15 Mataram by applying for the Course Review Horay learning method. This research is a classroom action research conducted in three cycles, and each cycle consists of five stages, namely the planning, action, observation, evaluation, and reflection stages. The results showed that there was an increase in activity and student learning achievement from cycle to cycle. The average value of student learning achievement for the first cycle, second cycle, and third cycle is 72,60; 83,87 and 86,30. The classical completeness in succession achieved is 74,91%; 83,87% and 93,54%. While the average score of student activity in cycle I, cycle II, and cycle III was 8.67 with quite active activity criteria, 10.5 with active activity criteria, and 12.5 with activity criteria very active. By paying attention to the results and work indicators that are achieved, it can be concluded that the application of cooperative learning models with the Course Review Horay method can increase the activity and learning achievement of students of class VII F of SMP Negeri 15 Mataram.

Abstract

Pare leaf (Momordica charantia L) is known to have potential as anti-bacterial and anti-fungal agent. This plant contains tannins, flavonoids, saponins, alkaloids, and triterpenoids. The administration of pare leaf methanol extract was hypothesized to increase inhibition zone in Candida albicans and Rhodotorulla sp colonies. The aim of this study was to determine antifungal activity of pare leaf methanol extract (PAME) against Candida albicans and Rhodotorulla sp. The method used in this study was well-diffusion method. Medium used for culture was MHA and each petri dishes was inoculated with suspension of either Candida albicans or Rhodotorulla sp., followed by making wells using sterilized straw. Pare leaf extract was added into each well at various concentration of 20%, 40%, 60%, 80%, 100%. Data was analyzed qualitatively based on the diameter of the inhibition zone to determine antifungal activity. The study was designed as an experiment with a completely randomized design. Results showed that the largest inhibitory zone was 12 mm at a concentration of 100% for inhibiting candida Albicans while for inhibiting Rhodotorulla sp was 8 mm. Statistical test produced a significant difference, indicating that pare (Momordica charantia L) leaf methanol extract was able to inhibit the growth of Candida albicans and Rhodotorulla sp.

Abstract

Durian adalah buah yang banyak tumbuh di Indonesia. Biji durian adalah limbah yang belum dimanfaatkan secara maksimal dan dapat digunakan sebagai bahan baku pembuatan bioetanol. Bioetanol merupakan salah satu jenis biofuel (bahan bakar cair dari pengolahan tumbuhan) disamping biodisel. Proses pembuatan bioetanol dilakukan dengan proses fermentasi dengan bantuan Saccaromices serevisiae. Penelitian ini bertujuan untuk mengetahui pengaruh pH dan jenis sampel yang paling berpengaruh pada proses pembuatan bioetanol. Penelitian dilakukan dengan sampel biji durian basah dan kering yang dihidrolisis dengan H2SO42,5% selama 3 jam pada suhu 70oC, kemudian diukur kadar glukosa reduksinya dan difermentasi dengan variasi pH (3, 4, 5, dan 6) selama 48 jam. Larutan fermentasi dimurnikan dengan destilasi dan diukur kadar etanol yang dihasilkan dengan spektrofotometer UV-Vis dengan λ 214 nm. Etanol dengan kadar 47,02% didapatkan dari sampel kering dengan pH 4

Abstract

This research aims to apply analysis correspondences in interpreting crimes that occurred in the Polresta Makassar Barat based on data obtained from local police agencies from July 2013 to July 2014. Correspondence analysis is a data analysis technique that is demonstrated through the rows and columns simultaneously from a contingency table bi-direction in low dimension vector. The variables involved in the analysis is a crime scene, time and age category. In Chi-Square analysis process obtained the result that there is no relation between crimes and age category. From the value the correspondence analysis between the crimes and a time of occurrence, obtained a value of inertia to the dimension of the first and second row are 74.10% and 24.30%. This means data obtained were able to explain the variability of the data amounted to 57% of total inertia. Based on the results of the output data plot between the crimes and times of occurrence can be explained that theft with violence and drugs tend to happen at 12:00-17:00 as for the theft of motor vehicles and heavy persecution tends to occur at 18:00-06:15.
