Abstract

This study aimed to determine the effect of concentration ethanol extract from tembelakan leaf (Lantana camara Linn) on bacteria growth of Staphylococcus aureus and Escherichia coli. Extraction was done by maceration using ethanol 96% and then separated using rotary evaporator. Antibacterial activity test of the ethanol extract by Well agar diffusion method. Variation in crude extract saponin used in this study was 5%, 10%, 15%, 20%, 25% and positive controls were used for comparison with Amoxicilin and Chloramphenicole concentration of 25 µg/mL and DMSO as a negative control. The results of antibacterial activity test is indicated by the formation of growth inhibitory region S. aureus and E. coli. The result of growth inhibitory regions was analyzed by One way ANOVA. One way ANOVA test results indicate that there are effects of ethanol extract concentration of tembelekan leaf (L. camara Linn) against S. aureus and E. coli. Effective concentration of ethanol extract tembelekan leaf (L. camara Linn) when compared with positive control to inhibit the growth of S. aureus and E. coli is at 25% with a relatively strong antibacterial activity. Test with phytochemicals screening method which is showed that tembelekan leaf contains the flavanoid, saponins, and tannins compounds as antibacterial

Abstract

The purpose of this study was to obtain information about the types of plants used by the Kaili Da’a tribe in life cycle ceremonies that are still preserved for generations in Uwemanje village, Kinovaro district, Sigi district. The research population is all people who live in Uwemanje Village, Kinivaro District, which are spread over 4 hamlets. The research method uses survey research with the help of interview questionnaires. Interviews were conducted on key respondents and general respondents. Key respondents were selected by purposive sampling as much as 10% of the population, namely the people who were considered to be the most knowledgeable about the ins and outs of this ceremony, such as Sando, traditional leaders, village heads and village priests. Meanwhile, general respondents are people who are recommended by key respondents with a record that they are at least 30 years old and are married or have a family. The data and information in this study were processed descriptively. Types of plants/plants used in life cycle ceremonies consist of 21 species, namely: rice (Oryza sativa L.), coconut (Cocos nucifera L.), banana (Musa paradisiaca L.), cocor duck (Kalanchoe pinata L.), areca nut (Areca catechu L.), turmeric (Curcuma domestica L.), nail paci (Lawsonia enermis L.), bogenvil (Boganvillea glabra L.), pandanus (Pandanus amarylifolius L.), jatropha (Jatropha curcas), forest basil ( Ocimum sanctum L.), moringa (Moringa oleifera L.), shallot (Allium cepa L.), Bengal grass (Eleusine indica L.), hibiscus (Hibiscus tiliaceus L.), peacock flower (Caesalpinia pulcherima L.), betel (Piper betle L.), keluwih (Artocarpus camansi L.), jasmine (Jasminum sambac L.), palm sugar (Arenga pinnata), and red sugar cane (Saccharum officinarum L.). The percentage of utilization of plant parts that are most directly utilized is the leaves which amount to 14 with a percentage of 65.66%, flowers amount to 4 to 16.67%, fruit to reach 3 to 12.5%. The least used parts are rhizomes, seeds, tubers, roots and stems with a percentage of 5.17%.

Abstract

The immune sistem is a way of the body’s defense sistem to save the host from the invasion of outside pathogen. Based on how respon to disease, that differentiated into two immune system are innate and adaptive system. Because it an cant throgh the stomach, these pathogenic bacteria go to the small intestin as a site infection. In the intestine, V. cholerae bactesia adhere and colonize and invasion to intestinal epihelial cells. Protection mechanism to V. cholerae are the natural defense presence of tick mucosa on the surface of epithelial cells can inhibit pathogene to adhere tointestinal epithelial cells. One anothet defense namely innate immune system did by phagocytic cells to attac pathogen agent and adaptive immune system involves IgA to opsonization so that can increase intestinal mucosal immune system

Abstract

Biofertilizer can be used to replace chemical fertilizer so that soil quality is maintained and soil pollution can be avoided. The study aimed to determine the effect of biofertilizers with different compositions of microorganisms on the growth of maize plants. The research was carried out in a greenhouse. Maize plants were fertilized by two kinds of biofertilizers with different compositions of microorganisms. The first biofertilizer contained Azotobacter sp, Azospirillum sp, Rhizobium sp, Trichoderma sp, and Lactobacillus sp, and the second biofertilizer contained Strenotrophomonas sp. and Paenibacillus polymyxa. As controls, maize plants were fertilized by sterilized those biofertilizers. The results showed that the second biofertilizer increased the dry weight of the maize plant. Meanwhile, the first biofertilizer did not increase it. Several things must be considered in the application of biofertilizers, such as the composition of microorganisms, type of plant, level of fertilization, and the method of applying fertilizer to the plant.

Abstract

Provision of Vanilla (Vanilla planifolia Andrews) with traditional cultivation often has problems, including the availability of unhealthy seeds due to disease caused by Fusarium oxysporum. This disease can thwart vanilla plantations up to 85% because the pathogen can infect all parts of the vanilla plant making it difficult to control efforts. Alternative efforts were made to overcome this problem, namely through the initiation process in tissue culture by combining the hormones IAA (indole-3-acetic acid) and BAP (6-benzylaminopurine). This study aims to determine the effect and the maximum concentration of the combination of IAA and BAP on the initiation of vanilla plants. This study was conducted based on a completely randomized design (CRD) with 5 treatments and 3 repetitions. This treatment consisted of: A (MS + 0.1 ppm IAA + 1 ppm BAP), B (MS + 0.2 ppm IAA + 1 ppm BAP), C (MS + 0.3 ppm IAA + 1 ppm BAP), D (MS + 0.4 ppm IAA + 1 ppm BAP), and E (MS + 0.5 ppm IAA + 1 ppm BAP). Observations were made after 40 days from the planting process. The results showed that the concentration of the combination of IAA and BAP can affect the growth and organogenesis of the initiation of vanilla plants (Vanilla planifolia Andrews). Treatment C (MS + 0.3 ppm IAA + 1 ppm BAP) was the best concentration from this study, with average values: number of shoots (1), shoot length (1.73 cm), number of roots (1), and number of leaves (1.33).
