Abstract

[APLICATION OF TWO AMELIORANT TYPES OF OKRA PLANT PERFORMANCE (Abelmoschus esculentus) IN ULTISOL]. This study aims to determine the dosage of dolomite lime and the type of organic fertilizer that can produce the highest performance of okra plants. This research is an experiment that was compiled based on factorial CRD. The first factor is dolomite dosage, which consists of three levels; 1.11 tons/ha, 1.76 tons/ha, and 2.40 tons/ha. The second factor is the type of organic fertilizer consisting of three types; chicken manure, cow manure, and palm oil solid organic fertilizer. The results showed that the dolomite dose of 2.4 tons/ha produced the highest number of fruits/plants (5.8 fruits) and the heaviest fruit/plant weights (82.1 g). Chicken manure and cow manure produce the highest plant height performance okra (29.8 cm - 31.6 cm), the largest stem diameter (72.8 mm - 73.8 mm), the highest number of branches (3 stems), the number most fruits / plants (5 - 7) and the largest fruit / plant weight (72.4 g - 81.4 g). The interaction between dolomite dosage and organic fertilizer did not significantly affect the performance of okra plants.

Abstract

This study aimed to investigate research about cytotoxicity correlation level of Phaleria macrocarpa (Scheff) Boerl also known as Mahkota dewa leaves methanol extract against  MCF-7 cell in vitroto investigate the relationship between them in the goal to investigate alternative low cost herbal medicine agents to fight breast cancer. Cytotoxicity properties of samples against MCF-7 breast cancer cell lines was performed by using the Microtetrazolium (MTT) assay against MCF-7 cell line. The correlation between concentration of crude and cytotoxic activity was interpreted by statistical analyses. The study showed that P. macrocarpa leaves extracts showed cytoxicity activity against breast cancer MCF-7 cell lines which IC50 concentration showed at 15 µg/mL  Correlation between concentration of extract and cytotoxicity property (absorbance value) were founded in weak relationship (R = 0.372, R2 = 0.138).  It could be effect of many different compounds in the P. macrocarpa  leaves methanol extracts may cause the pharmacological interactions, so lower or higher concentration will be antagonistic effect on absorbance or cell viability. Further study on its mechanism pathway on revealing against breast cancer could be explored. Furthermore, the natural product derived from P. macrocarpa leaves methanol extracts have potential use as alternative drugs against breast cancer.

Abstract

Cancer is recognized as global threat to human development and it was estimated that in 2030 there will be 22.2 million new cases of cancer and 12.7 million cancer-related deaths worldwide. Herbal medicine plant till this day all over in the word is still the main source and one of the most important fields of traditional medicine agents to fight breast cancer. The usage of plants is still important because has its own beaviour advantages such as low toxicity, easy to get, cheap and has less side effect if it is used in a right. One of this plant it has been used as a traditional medicine is a Phaleria macrocarpa (Scheff) Boerl) also known as Mahkota Dewa from Papua island. It has been used traditionally for treatment of cancers in Indonesia and also to cure many diseases. The therapeutic effect of Phaleria macrocarpa (Scheff) Boerl, is related to the its bioactive compounds contents. There are many reported compounds from Phaleria macrocarpa (Scheff) Boerl, which are found, reported and published such as Icariside, phalerin, mangiferin, gallic acid, 29-Norcucurbitacin, gentiobioside and glucoside. All compounds reported above have already published as anticancer agents,where anticancer activity were detected and showed against Hela cells, leukemia cells, cervical cancer, breast cancer, and L1210 cells. Research on Phaleria macrocarpa (Scheff.) Boerl fruit and leaves merit have been done and published, however, there are very limited research on linked correlation between the concentration of compounds and its the cytotoxicity  level. Because of that, research about correlation level of Phaleria macrocarpa (Scheff) Boerl leaves extract still need to investigate to find the relationship between them in the goal to investigate alternative low cost herbal medicine agents to fight breast cancer especially useful for low income people, thus, information about Phaleria macrocarpa (Scheff.) Boerl.Leaves became more complete. Cytotoxicity properties of samples against breast cancer cell lines was performed by using the MTT assay against MCF-7 cell line. The correlation between concentration of crude and cytotoxic activity was interpreted by statistical analyses. The study showed that Phaleria macrocarpa (Scheff) Boerl.) leaves extracts showed cytoxicity activity against breast cancer MCF7 cell lines. Correlation between concentration of extract and cytotoxicity property (absorbance value) were founded in weak relationship (R = -0.37181). It could be effect of many different compounds in the Phaleria macrocarpa (Scheff) Boerl.) leaves methanol extracts may cause the pharmacological interactions, so lower or higher concentration will be antagonistic effect on absorbance or cell viability.Further study on its mechanism pathway on revealing against breast cancer could be explored. Furthermore, the natural product derived from Phaleria macrocarpa (Scheff) Boerl.) leaves extracts have potential use in cheap alternative agents against breast cancer

Abstract

The objectives of primary education is to give students basic competence to develop their life as an individual, as part of a community and as citizen. On the other hand, the objective of a nature science in primary education is to give students competencies to develop their knowledge, skill, and attitude that is useful in their daily life. Nature science in primary education refers to knowledge rather science. It means that what is teach in primary education are practice things, useful to the living and then in any circumstances and any life aspects. The mission and objectives in teaching nature science in primary education is related to the environment problems in school environment as well as community environment problems in school environment around the students. The environment around the kids should have been used by the teacher to teach natural science because the environment itself the objective, source, and learning facilities. The manufacture of teaching natural science in primary education can be obtained by doing a meaningful learning process.

Abstract

[EFFECTS OF PALM OIL SLUDGE SUBTITUTION FOR SYNTHETIC N FERTILIZER ON GROWTH AND YIELD OF SWEET CORN]. Palm oil sludge (POS) contains high concentrations of organic nitrogen dan its can serve as an alternative for synthetic nitrogen fertilizer. Objective of this study was to compare the growth and yield of sweet corn as amended with different compositions of synthetic N fertilizer and palm oil sludge. Six compositions, each containing 138 kg N/ha were assigned as the treatment and arranged in a randomized complete block design with three replications. These were 100% synthetic fertilizer, 80% synthetic fertilizer + 20% POS, 60% synthetic fertilizer + 40% POS, 40% synthetic fertilizer + 60% POS, 20% synthetic fertilizer + 80% POS, and 100% POS. The results of this study indicated that the plot amended with 60% synthetic fertilizer + 40% POS produced the highest plant stature (176.4 cm), stem diameter (2.40 cm), leaf area (8712.82 cm2 ), plant fresh weight (375.19 g), plant dry weight (136.68 g), and husked ear length (17.93 cm). However, the highest observed husked ear yield was only about 61.6 % the yield potential of the sweet corn variety.

Abstract

Area under rubber tree stands has an economic potential for production of ginger if proper fertilizer application is implemented. Purpose of this study was to determine the effects of N and P fertilizers application on N uptake, N efficiency and yield of ginger grown under rubber tree stands. The experiment was laid in RCB design with a factorial arrangement of the treatments, consisted of four levels of N fertilizer (0, 3.375, 6.75, and 10.125 g plant-1) and three levels of P fertilizer (0, 9, and 18 g plant-1). There were three replications and 18 plant on each experimental unit. Results indicated that there were significant interaction effects between N and P fertilizers on N uptake and N efficiency. The expected maximum N efficiency of ginger plant was 14.01% as N fertilizer applied alone at 12.56 g plant-1. Similarly, the highest N uptake (1.170 g plant-1) was observed on N application at 13.755 g plant-1 without P. Weight of ginger rhizome was predicted to increase 0.2203 g plant-1 on 1 % increment of N uptake efficiency.
