Temu kunci (Boesenbergia pandurata) merupakan tanaman yang memiliki kandungan flavonoid dan fenol serta banyak dimanfaatkan sebagai obat tradisional. Namun, hingga kini temu kunci belum pernah diekstraksi dengan metode ekstraksi menggunakan microwave. Ekstraksi dengan menggunakan microwave memiliki potensi yang baik untuk dikembangkan pada temu kunci sehingga dapat dihasilkan ekstrak temu kunci yang memiliki kadar total fenol dan flavonoid yang tinggi dengan waktu ekstraksi yang lebih sedikit. Oleh karena itu, penelitian ini bertujuan untuk mengetahui kadar total fenol dan flavonoid ekstrak temu kunci yang diekstraksi dengan menggunakan microwave pada berbagai variasi waktu. Pembuatan ekstrak temu kunci dilakukan dengan meradiasi temu kunci dalam campuran etanol 70% pada tipe pemanasan Low selama 15 menit yang dibandingkan dengan tipe pemanasan Medium selama 3, 5, 7, 9, dan 12 menit. Berdasarkan penelitian, rendemen yang dihasilkan berkisar antara 5,91% - 9,7%. Kadar total fenol yang dihasilkan berkisar antara 6,69% - 9,18%, sedangkan kadar flavonoid berkisar antara 13,46% - 21,41%. Rendemen ekstrak temu kunci semakin meningkat dengan waktu ekstraksi yang lebih lama dan suhu yang lebih tinggi. Kadar total fenol dan flavonoid tertinggi adalah pada tipe pemanasan Medium selama 7 menit pada suhu 57 ℃.Total Phenol and Flavonoid Content of Fingerroot (Boesenbergia pandurata) by Microwave Assisted Extraction. Fingerroot (Boesenbergia pandurata) is a plant that contains flavonoids and phenols. It is often used as traditional medicine. However, fingerroot has never been extracted using a microwave-assisted extraction method. In fact, extraction using microwave has good potential to be developed so that the fingerroot extracts can be produced which have high levels of total phenols and flavonoids with less extraction time. Therefore, this study aims to determine the total phenol and flavonoids extracted by microwave at various times. The preparation of fingerroot extract was carried out by irradiated fingerroot in 70% ethanol mixture on Low heating type for 15 minutes, compared to Medium heating type for 3, 5, 7, 9, and 12 minutes. Based on the research, the yield produced ranged from 5.91% - 9.7%. The total phenol content produced ranged from 6.69% - 9.18%, while the levels of flavonoids ranged from 13.46% - 21.41%. The yield of fingerroot extract increased with longer extraction time and higher temperature. The highest total phenol and flavonoid levels were the Medium heating type for 7 minutes at 57 ℃.

Water is a basic need for humans. Human life cannot be separated from water, especially the need for drinking water. Water needs have been sourced from groundwater, river water, rainwater, mountain water, and treated seawater. Water that humans need includes clean and healthy useable water for cooking, washing, and bathing, as well as water that is fit for consumption for drinking purposes. The main use of water and very vital for life is the use of drinking water. Drinking water from depot companies for drinking water refills is an industrial business that processes raw water into ready-to-drink water by consumers. This study aims to determine the presence of Escherichia coli contamination in drinking water sold by refilled drinking water depots in the Ciangsana region. The results of the microbiological analysis showed two out of ten samples were positive for coliform fecal, Escherichia coli.

Background: Actinomycetes are groups of bacteria that play an important role in pharmacy and medicine in their ability to produce secondary metabolites in the form of bioactive compounds with various chemical structures and biological activities. The genus Streptomyces produces more than 70% of all described actinomycetes natural products. In particular, antibiotics represent the largest group. Through mutations, bacteria may survive chemotherapy. Thus its infection is hard to eradicate. Therefore the search for new potent bioactive compounds is important Methods: Isolate preparation, Production, and extraction bioactive compound, Crude extract antibacterial test, Identification of bioactive compound Results: There are antibacterial activities per 100 µl crude extract.

Phlebotomy is the process of drawing blood from the circulatory system through a puncture to obtain a sample. Venous blood collection is done using a tourniquet as a damming device that serves to see the vein under the skin tissue. In adults, one of the veins used is the cubital fossa and in infants using the superficial jugular vein or in the superior sagittal sinus. Platelets are disk-shaped cells with a diameter of 2-5 mm. Under normal circumstances, the number of platelets is about 150,000-450,000 / ml of blood and its life span is about 1- 2 weeks or about 8 days. Platelets are made of phospholipid substances that are important for clotting, maintaining the integrity of blood vessels and repairing damaged small blood vessels. The purpose of this study was to determine the comparison of platelet levels in vein damming at 1 minute and 2 minutes. This study was conducted in the MM2100 industrial area, samples obtained from employees who did Medical Check Up and obtained as many as 30 respondents and 60 samples. The results showed that employees in the MM2100 industrial area with average platelet levels of 274,133/µl of blood at 1 minute and average platelet levels of 278,266/µl of blood at 2 minutes. This study uses the Paired Sample T-Test method, the results obtained with a sig value of 0.229 which means there is no difference in the damming time of 1 minute and 2 minutes on platelet levels.

In the last 30 years there have been increasing demand of agarwood. Unlimited hunting of agarwood causing it become threatened species. Aquilaria spp. is the main genus producing agarwood that considered as threathened species. Conserving Aquilaria spp. as germ plasm needs is essential against destruction. Arbuscular mycorrhizal fungi (AMF) have been used as inoculant to increase the growth of Aquilaria spp., but information about the existence of AMF in Aquilaria spp. rhizosphere has not been reported. This research was carried out with objective to identify AMF from Aquilaria spp. rhizosphere. Soil and root samples from rhizosphere of Aquilaria spp. taken from four location that is: Carita (A. malaccensis), Ciapus (A. filaria), Cifor (A. crasna & A. malaccensis), and Bantar Kemang (A. beccariana, A. crasna, & A. malaccensis). Roots staining was conducted with modified Phillips and Hayman procedure (1970). Soils sample was run dry wed and placed in pot culture with Pueraria javanica as the host plant. Spore was separated from pot culture using wet sieving and decanting method continued with centrifugation. The result showed the occurrences of AMF in Aquilaria spp. roots i.e. external hypha, internal hypha, coiled hypha, arbuscules, and vesicles. All AMF colony structure found in Aquilaria spp. roots show asosiation bettwen the plant and AMF. Four species of AMF were found i.e. Glomus sp.1, Glomus sp.2, Gigaspora albida, and Dentiscutata sp.

Plant host symbiosis is close related to soil microbial abundance. Soil microbial abundance will affect soil quality and fertility, thus will improve plant growth. Studies on soil microbial abundance in succulent plant rhizosphere, especially in Indonesia, are scarce. This study aims to observe soil microorganisms' existence and their abundance on succulent plant rhizosphere. This research used two primary methods to isolate Arbuscule Mycorrhizal Fungi (AMF) and actinomycetes. The spore extraction (soil separating) method was used to obtain AMF spores, followed by the root staining method to observe AMF infection on the plant roots. Serial dilution and pour plate method were used for isolation of Actinomycetes. The isolation results showed a high number of Actinomycetes distribution up to 3.3 x 106 Actinomycetes CFU/g from the plant Echinocactus grusonii, while AMF spores displayed the most elevated number up to 47 spore/25g from the plant Deuterocohnia sp. The percentage of AMF root infection is covered by 27,9% median. AMF identification was based on spore. The result showed an abundance presentation of Actinomycetes in each soil sample. AMF and Actinomycetes existence displayed symbiotic interaction between succulent plants and soil microorganisms. AMF and actinomycetes play the role of endophytes that help the growth of cacti, generally have a dry growing environment, and limited nutrition by this symbiotic interaction. Actinomycetes distribution in rhizospheric soil will increase plant growth-promoting factors activity. Eventually, the implications of research results are to explore the abundance and biodiversity of soil microorganisms from succulent plant rhizosphere that lacked exploration.
