Abstract

Recently, the popularity of coffee is gaining popularity. The researcher found that the benefit of coffee was not refreshing only but also improved the quality of health. These effectsexistdue to the natural bioactive compounds found in the coffee. The bioactive compounds of coffee have activity as an antioxidant, anti-inflammation, anti-microbe, and recently as antidiabetic. The major compounds found in coffee were chlorogenic acid, trigonelline, diterpene, and Maillard reaction product (exp.melanoidin). The objective of this study was to explore the bioactive compounds of coffee and the potency antidiabetic, conducted by in-vitro, in-vivo, clinically, and epidemiology intergrately. The in-vitro analysis shown thatcoffee had activity asan inhibitor a-glucosidase, the compounds were chlorogenic acids. In the in-vivo study,coffee brewwas able to reduce blood glucose concentration of a rat model of type-2 diabetes by increasing insulin sensitivity. Caffeine and chlorogenic acids probably had an antagonist effect on glucose response. At the early stage of a clinical study, blood glucose concentration tend too increasedacutely and gradually reduces along with insulin sensitivity higher. A chlorogenic acid had a potency to decrease blood glucose concentration byseveral mechanisms such as -glucosidase inhibitory and raise insulin sensitivity. Furthermore, epidemiology studied shown that the efficacy of coffee consumption in the long-termwas able to reduce the risk of diabetes type 2. The effectiveness of coffee as antidiabetic depends on some factors such as gender and variation of coffee such asvariety, brewing technique, and frequency consumption of coffee.ABSTRAK Konsumen kopi saat ini makin meningkat, kepopulerannya ditandai dengan industri hilir kopi yang merebak di tengah-tengah masyarakat. Konsumsi kopi selain memberikan efek menyegarkan juga memiliki manfaat dalam meningkatkan taraf  kesehatan konsumennya. Komponen bioaktif pada kopi memiliki aktivitas seperti antioksidan, antiinflamasi, antimikroba dan antidiabetes. Kandungan biokatif kopi yang berperan dalam aktivitas tersebut adalah asam klorogenat, trigonelin, diterpen dan produk reaksi Maillard (cth.melanoidin). Tujuan dari tulisan ini adalah menggali senyawa bioaktif yang terdapat pada kopi dan potensinya sebagai antidiabetes secara terpadu baik secara in-vitro, in-vivo, klinis dan epidemiologi. Berdasarkan penelitian secarain–vitrobahwa komponen bioaktif kopi yang berperan dalam menghambat aktivitas a-glukosidase adalah asam klorogenat. Secara in-vivobahwa seduhan kopi yang dikonsumsi oleh tikus penderita diabetes menghasilkan kadar glukosa darah yang menurun karena peningkatan sensitivitas insulin. Efek kafein kemungkinanberlawanan dengan asam klorogenat terhadap glukosa darah. Pada awal pengujian secara klinis kadar glukosa darah akan meningkat secara akut dan kemudian menurun seiring meningkatnya efek asam klorogenat. Asam klorogenat akan berperan dalam menghambat transportasi glukosa dan meningkatkan sensitivitas insulin. Penelitian secara epidemiologi menunjukkan bahwa konsumsi kopi dalam jangka waktu yang lebih lama dapat menurunkan resiko penyakit diabetes mellitus tipe 2. Persentase penurunan penyakit diabetes melitus dipengaruhi oleh faktor gender dan variasi kopi seperti jenis, teknik menyeduh dan frekuensi konsumsi kopi.

Abstract

Nowadays, processed natural rubber products such as crumb rubber have become the demands of global consumers who are oriented towards export markets. Therefore, the economic impact is felt more, but there are still other consequences. The consequences are not only economically beneficial but can also be detrimental to environmental conditions. The process of making natural rubber into crumb rubber causes a negative impact by means of air pollution in the form of odour, which is rarely noticed. The purposes of this study were to analyse the ammonia concentration resulting from the processing of natural rubber into crumb rubber, and to identify the impact of ammonia contamination on the environment, particularly human health. This research was conducted using a review method with the help of colandr machine learning. The results of the review show that the concentration of ammonia produced from the processing of natural rubber into crumb rubber in Indonesia has passed the specified quality standard threshold. It is found to impact the environment such as damage to aquatic ecosystems and air quality, as well as effects on human health such as respiratory problems.

Abstract

Coffee is usually consumed by adding sugar, cream, or milk. Adding these ingredients, especially sugar, can cause new disease problems. The market is starting to look for natural sweeteners that do not cause health problems, such as stevia. The objective of this research was to identify the sensory attributes and chemical components of some variety of stevia coffee formulations. Sensory attributes were identified through a focus group discussion (FGD), and sensory profiling to choose the best formulation was determined using the Rate-All-That-Apply (RATA). The FGD members were nine panelists, while the RATA sensory evaluation used 30 panelists. Chemical analysis carried out includes water (gravimetry), ash (gravimetry), and antioxidant capacity (spectrophotometry). In this research, four distinct formulations of stevia coffee, A1 (0% stevia), A2 (2% stevia), A3 (4% stevia), and A4 (7% stevia), were utilized. Results indicate that varying stevia concentrations significantly influence the resulting coffee's sensory characteristics. Attributes identified through FGD include color (dark brown), aroma (green/leafy, sour, roasted, spicy), taste (acid/sour, sweet, bitter, green, spice) and aftertaste (over, bitter and sweet). Statistical analysis showed that eight out of thirteen sensory attributes had significant differences (p<0.05) among the four samples. Sensory evaluation of the selected sample, A2 (4%), revealed a favorable taste profile characterized by sweetness and sourness. Moreover, the chosen formulation exhibited a notable antioxidant activity level of 83.13%. These findings underscore the potential of stevia coffee as a flavorful and health-conscious alternative, offering valuable insights for product development and consumer acceptance.

Abstract

Endophytic fungi living in medicinal plant tissues are potential bioactive metabolite sources for drug discovery and development. However, the research regarding endophytic fungi associated with Indonesian medicinal plants is still limited. This study aimed to explore the biodiversity of endophytic fungi associated with the medicinal plant Uncaria gambir (Hunter) Roxb. var. udang and their antibacterial activities. Twenty-seven endophytic filamentous fungi were isolated from the surface-sterilized leaves, stems, and roots of Uncaria gambir (Hunter) Roxb. var. udang collected in Jasinga, Bogor, West Java, Indonesia. The observation based on the morphological characters both macroscopically and microscopically, as well as chemical profiling using thin layer chromatography (TLC), revealed that some of the isolated endophytic fungi were identical. Overall, the isolated endophytic fungi consist of six Coelomycetes, three Dematiaceae, four Pestalotiopsis sp., two Penicillium sp., one Aspergillus terreus, and two fungi were unidentified. Antibacterial activities of the ethyl acetate extract from the isolated endophytic fungi associated with Uncaria gambir (Hunter) Roxb. var. udang were observed against E. coli, B. subtilis, S. aureus, and M. luteus. Twelve types of isolated endophytic fungi from Uncaria gambir (Hunter) Roxb. var. udang exhibited antibacterial activities.
