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

Traditional green grass jelly has a limited shelf life due to its poor microbiological and physical (syneresis) properties. Improvement of green grass jelly quality has been done by reformulation of the jelly with the combination of thermal application (steaming and pasteurization). The objective of this research was to study the stability of physical and microbiological properties of steamed (CHK) and pasteurized (CHP) green grass during storage at low temperature (5-100C). CHP have greater syneresis than CHK, with the level of syneresis reaching 6.66% and 4.90%, respectively, on the 15th day of storage. In general, up to 15 days of storage, CHK could preserve its quality better than CHP, in term of syneresis level, texture, and green color. It was also shown that pH is one parameter that is stable during the storage of both CHK and CHP, which is ranged between 6.5-7.3. The microbiological quality of both fresh and stored pasteurized jelly contained fewer microorganisms (1 log) than the steamed jelly. Pasteurized green grass jelly has a prolonged shelf life until 12 days of storage at refrigerated temperature.

Abstract

Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae) is a new pest in maize cropping inIndonesia. These insects originated in the Americas and have spread to several countries and causecrop loss in corn. Beginning in 2019, this pest has reportedly attacked corn plants in the Sumatraregion. This activity aims to find out the existence of S. frugiperda in the area of Petir Village,Dramaga Sub-District, Bogor District. The survey results show that S. frugiperda has attacked thecorn crop in Petir Village. Specific characters found in S. frugiperda are inverted "Y" in the headcapsule and a black dot pattern on the abdomen (point four and trapezoid). S. frugiperda larvae found in the village of Petir attack the corn growing point, but the population is still low. Entropathogenicfungi are bioinsecticides that can be used to control pests. Metarizhium rileyi is an entomopathogenicfungus that has the potential to control S. frugiperda in maize. The results indicated that M. rileyi waseasily propagated en masse in agar medium and in good virulence in S. frugiperda.

Abstract

Liberica coffee is one of the coffee species in commercial trade in Indonesia. The coffee is produced in Tanjung Jabung Barat Regency, Jambi, Indonesia which distributed into 5 sub-districts (Betara, Bram Itam, Kuala Betara, Pengabuan, Senyerang). Information about liberica coffee from Jambi is still limited, thus more exploration is needed. The objectives of this study were to characterize the morphology of the leaf and fruit, the physicochemical characteristics which include the dimension (length, width, thickness), mass, bulk density, colour (L*, a*, b*), moisture contents, TSS (total soluble solids), pH, and antioxidant capacity (DPPH IC50, FRAP) of green and roasted (commercial level) liberica coffee from the above 5 sub-districts. The studies showed that liberica coffee from 5 sub-districts in Tanjung Jabung Barat Rgency, Jambi had various leaf and fruit appearances which were characterized by various size and colour of coffee cherries. Green coffee from different sub-districts owned various physicochemical (width, volume, mass, bulk density, moisture content, TSS) and antioxidant capacity of green coffee. Green coffee from Betara and Pengabuan were associated with high TSS, L* and b* value, while green coffee from Bram Itam and Senyerang were associated with high mass, moisture content and a* value. The highest anti-oxidant capacity was produced by green coffee from Betara and Kuala Betara (DPPH IC50). Meanwhile, roasted coffee produced from green coffee from the 5 sub-districts with similar roasting level (similar L*) produced similar a*, b* value, mass and TSS. However, physicochemical characteristics (length, width, volume, bulk density, moisture content) and antioxidant capacity of these roasted beans varied.

Abstract

Diabetes mellitus (DM) is one of the non-communicable diseases that could be prevented by consumption of foods capable of maintaining blood glucose at a safe level. Phenolic compounds are components in food that affect blood glucose levels. Lemongrass and bay leaf are Indonesian spices commonly used for cooking and contain phenolic compounds that have potential as antidiabetic compounds. The aim of this study was to evaluate the effect of adding lemongrass and bay leaves water extracts on the GI value of cooked white rice. Lemongrass and bay leaves containing phenolic compounds were extracted with water and added to white rice during the cooking process or sprayed on cooked rice. The glycemic index of the tested food measured using the ISO 26642 method showed that the addition of lemongrass extract and a combination of lemongrass and bay leaf extract with total phenolic content (TPC) of 570 mg GAE/100 g and 565 mg GAE/100 g, respectively, on cooked white rice IR 64 resulted in the GI reduction in the cooked rice by 23 and 27%, respectively. These reduction was higher than those resulted from the addition of lemon grass or the combination of lemon grass and bay leaf extract during the cooking process, i.e. 9 and 13%, respectively.

Abstract

Coffee has a positive effect on health due to its high content of antioxidant compounds. The potential antioxidant activity of coffee is strongly influenced by its chemical compound profile. This study aimed to analyze the effect of different solvents on the chemical metabolites profile, antioxidant activity, and to determine the relevant chemical functional groups which positively contribute to the coffee’s antioxidant activity. In this study, methanolic extract of coffee samples from robusta and arabica varieties were fractionated by liquid-liquid fractionation method using four solvents with different polarities. ABTS (2,2'-azinobis (3-ethylbenzothiazoline-6-sulphonic acid) and cupric reducing antioxidant capacity (CUPRAC) assays were applied to measure the antioxidant activity of the coffee fractions. Fourier Transform Infrared- Attenuated Total Reflectance (FTIR-ATR) based chemometric approach was used to identify the compound functional groups as the fingerprinting profile of the coffee fractions. Correlation between the FTIR-ATR fingerprinting with the antioxidant activity of the coffee fractions was studied using multivariate data analysis, i.e. Principal Component Analysis (PCA) and Orthogonal Partial Least Squares (OPLS). From this study, a reliable PCA model to evaluate the effect of different solvents to FTIR-ATR fingerprinting profile was produced. The correlation between FTIR-ATR fingerprinting profile with the antioxidant activity and the characterization of the chemical functional groups relevant to its antioxidant activity can be analyzed by a reliable OPLS model obtained. This study suggests that the highest antioxidant potential in coffee is found in ethyl acetate fraction both in robusta and arabica coffee samples, while the relevant chemical functional groups having positive correlation to antioxidant activity of coffee were phenol, carbonyl, cyclohexane, aromatic, amide, phenyl, amino, and alkene groups.

Abstract

Indonesians use refilled drinking water which can be obtained at depots because of practical and affordable reasons. Low levels of sanitation and hygiene and storage of refilled drinking water for an extended period can lead to the possibility of the growth of indicator and pathogenic microorganisms such as Coliform and Escherichia coli (E. coli). This study aims to evaluate the application of drinking water refilling stations (DWRS) sanitary hygiene, microbiological quality and safety of refilled drinking water and its changes during storage. Samples of refilled drinking water were taken from two DWRSs for each region in five areas of DKI Jakarta including West, East, South, North, and Central Jakarta. The treatments in this study were refilled drinking water storage in gallons of closed and open-closed conditions at room temperature (28 + 2°C) for 0, 7, and 14 days. The results of observations showed that 30% (n=30) of depots complied with hygiene sanitation standards according to Permenkes RI No. 43 of 2014 (>70%). The analysis results showed that refilled drinking water at 0 days of storage, 100% met the TPC (5 Log CFU/mL), 20% met the total Coliform standard (0 Log CFU/mL), and 80% met the E. coli standard (0 Log CFU/mL) according to Permenkes RI No. 492 of 2010. Storage times of 0, 7, and 14 days of refilled drinking water had a significant effect on TPC and total Coliform (P < 0.05), but had no significant effect on E. coli (P > 0.05) in gallons with closed and open-closed conditions. Keywords: Coliform, DWRS, E. coli, refilled drinking water
