Peuyeum: fermented cassava from Bandung, West Java, Indonesia

Laras Cempaka 한국식품연구원 2021 Journal of Ethnic Foods Vol.8 No.-

Peuyeum is a fermented cassava product from Indonesia. Peuyeum or cassava tapay is known as “Peuyeum Bandung,” whose name refers to a provincial capital in West Java, Java Island. Peuyeum is processed through fermentation and uses starter cultures in the form of yeast tapay. The word peuyeum comes from “meuyeum” or “memeram,” which in Sundanese—the native language of West Java—means an incubation. This is because the process to make it requires curing time for ripening. The cassava is peeled, cleaned, and boiled to soften the tissue, then the starter is added and incubated for a certain time. The skill of making peuyeum is a generational one, passed down so that this traditional food is still preserved, even though it has become the local specialty of West Java. Derivative products are now increasingly diverse, which are fried tapay, colenak (grilled peuyeum served with a mixture of brown sugar and coconut shavings), mixed fruit ice, peuyeum cake, and others. In fact, for all the abovementioned cuisines, it can be said that fermentation was applied in producing the various traditional food items. Philosophically, peuyeum represents societies, group solidarity, peace of mind, and language symbolism. Thus, this paper discusses the history, philosophy, process, and derivative products of peuyeum.

Abinaya Manivannan,Prabhakaran Soundararajan,Laras Sekar Arum,고정호,Sowbiya Muneer,정병룡 한국원예학회 2015 Horticulture, Environment, and Biotechnology Vol.56 No.6

This study investigated the effects of silicon (Si) nutrition on hydroponically grown Zinnia elegans under salinity stress. In this study, six treatments, the control (basal nutrients without NaCl or Si), Si 50 (1.8 mM), Si 100 (3.6 mM), NaCl 50 (50 mM), Si 50 + NaCl 50 (1.8 mM Si; 50 mM NaCl), and Si 100 + NaCl 50 (Si-3.6 mM + NaCl-50 mM), were employed. After 15 days of treatment, growth parameters, biochemical measurements, and antioxidant enzyme activities were examined. Salinity stress significantly reduced plant growth, biomass, photosynthetic parameters, and pigments, and increased the electrolyte leakage potential (ELP), lipid peroxidation, and hydrogen peroxide level. Interestingly, with Si supplementation, Z. elegans recovered from salinity stress. Si enhanced growth and photosynthesis, and prevented the decomposition of photosynthetic pigments. Moreover, the addition of Si increased membrane integrity, thereby reducing the ELP and lipid peroxidation levels under salinity stress. Furthermore, Si modulated the activity of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and guaiacol peroxidase (GPX) in scavenging excess reactive oxygen species (ROS). Additionally, Si increased the macronutrient and micronutrient contents. Therefore, augmentation with Si provided salinity resistance and enhanced the growth of Z. elegans.

Susanti, Ratna F.,Dianningrum, Laras W.,Yum, Taewoo,Kim, Yunje,Lee, Byung Gwon,Kim, Jaehoon Elsevier 2012 INTERNATIONAL JOURNAL OF HYDROGEN ENERGY - Vol.37 No.16

<P><B>Abstract</B></P><P>Continuous supercritical water gasification of glucose is investigated with a recently developed updraft gasification apparatus under various conditions: temperatures of 600–767 °C, residence times of 15–60 s, glucose concentrations of 1.8–15 wt% and without added a catalyst. The experimental gas yields are compared with predicted values at equilibrium that are estimated via Gibbs free energy minimization. Total gas yields and hydrogen gas yield increase with temperature. At 740 °C and 1.8 wt%, hydrogen gas yields become very high (10.5–11.2 mol/mol glucose). The hydrogen gas yields do not vary significantly with different residence times. The hydrogen gas yield decreases to 5.7 mol/mol glucose at 15 wt%, a value very close to the predicted value (6.3 mol/mol glucose). Only acetic acid is detected in the liquid effluents at temperatures above 740 °C, while 42 products are detected at 600 °C. The highest hydrogen gas yield obtained in this study is 11.5 mol/mol glucose at 25 MPa, 767 °C, and 1.8 wt%, for 60 s; this value is very close to the theoretical equilibrium hydrogen yield of 11.9 mol/mol glucose. Under these conditions, the carbon efficiency is very high (91%) and total organic carbon (TOC) in the liquid product is very low (23 ppm), indicating that glucose is almost completely converted to gaseous products. Comparison with other work under similar operating conditions shows that the current reactor is capable of attaining higher hydrogen gas yields at temperatures above 650 °C. Possible explanations for the higher hydrogen gas yields are presented.</P> <P><B>Highlights</B></P><P>► Almost theoretical maximum hydrogen yield achieved in SCWG of glucose without added catalysts. ► Experimental gas yields were very close to those of theoretically predicted values. ► Enhanced water-gas-shift reaction and flow stability leaded high H<SUB>2</SUB>/low CO yields. ► Acetic acid was most refractory intermediate in supercritical water.</P>

JATMIKO, Bambang,UDIN, Udin,RAHARTI, Rini,LARAS, Titi,ARDHI, Kholifah Fil Korea Distribution Science Association 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.3

The essential purpose of this study is to propose strategies for developing micro-, small-, and medium-sized enterprises (MSMEs) to realize sustainable competitive advantage by applying the SWOT analysis method. Thus, the main problems investigated in this study are: a) around 60-70% of MSMEs in Kulonprogo regency do not yet have access or financing from banks; b) lack of knowledge of production technology; c) in general, MSMEs business actors are still incorporated legal entities; d) MSMEs do not have a good financial administration and management system; e) coordination between MSMEs stakeholders has not been integrated; f) limited facilities and infrastructure of MSMEs, primarily related to technological tools; and g) limited access to raw materials so that MSMEs often get low-quality raw materials. This study employed a survey method with questionnaires and interviews. By using the Slovin tools sampling technique, the number of samples was 39 MSMEs in Kulonprogo Regency, Yogyakarta, Indonesia. The results of this study confirmed that the Kulonprogo MSMEs should pay attention to seven aspects of business management to achieve sustainable competitive advantage. The seven aspects are: 1) business strategy; 2) human resources; 3) information technology; 4) products; 5) promotion; 6) cooperation; and 7) corporate social responsibility (CSR).

"Lepet": Indonesian traditional food for Eid Al-Fitr celebrations

Wardana Ata Aditya,Setiarto R. Haryo Bimo,Wigati Laras Putri 한국식품연구원 2023 Journal of Ethnic Foods Vol.10 No.29

Indonesia, a country with diverse cultures, possesses a rich variety of cultural heritage. The aim of this review is to discuss the culture of lepet considering its ethnic perspective, preparation and consumption, nutritional and functional properties, safety, and future outlook aspects. Lepet, a traditional Javanese dish, consists of sticky rice, grated young coconut, coconut milk, cowpea, and salt. It is wrapped in young coconut leaves with a specific pattern, boiled, soaked, and then hung to cool and dry. The persuasive technique employed by Sunan Kalijaga, which combines Javanese cultural traditions and Islamic religious teachings, symbolizes lepet for the Javanese people. This method facilitated the spread of Islam by emphasizing the importance of purity and refraining from committing further mistakes after apologizing during the Eid Al-Fitri tradition. Lepet is rich in carbohydrates and some protein. It is gluten-free and offers benefits for bone and skin health due to its contribution of antioxidants, vitamins, and minerals. Proper handling and storage of lepet are vital to prevent the growth of harmful bacteria and extend its shelf life. Given the rising worldwide acknowledgment of Indonesian gastronomy, advancements in technology and distribution, creative adaptations, and a surging demand for convenience, the prospects for lepet appear bright in the future.

Background Factor VIII (FVIII) inhibitor diagnosis and surveillance in Indonesia are challenging owing to geographic conditions and the lack of laboratory facilities nationwide for inhibitor assays. This study aimed to determine the prevalence of FVIII inhibitors in children diagnosed with hemophilia A (HA) in Indonesia. Methods A cross-sectional study was conducted in 12 hospitals in eight provinces of Indonesia between 2020 and 2021. Factor VIII inhibitor screening was performed in a central hemostasis laboratory for all children with HA (≤18 yr) who had received a minimum of 10 exposure days to clotting factor concentrates. The FVIII inhibitor titer was determined using the Bethesda assay. Results Children (388) were enrolled in this study, including 219 (56.4%), 131 (33.8%), and 38 (9.4%) with severe, moderate, and mild HA, respectively. The prevalence of children who developed FVIII inhibitors was 37 out of 388 (9.6%). Factor VIII inhibitors were found in 25/219 (11.4%) severe, 11/131 (8.3%) moderate, and 1/38 (2.6%) children with mild HA. Thirteen children had low-titer inhibitors and 24 had high-titer inhibitors, with a median of 9.44 (1.48‒412.0) Bethesda Units. Among 13 children with low-titer inhibitors, eight underwent a confirmation test, of which five tested negative and were classified as transient. A significant difference in annual joint bleeding rate was found between patients with low and high inhibitor titers and those without inhibitors (P <0.001). Conclusion Factor VIII inhibitor prevalence in Indonesia was relatively low. However, the risk factors that may contribute to FVIII inhibitor development among Indonesian patients require further study.

Lara E Silva(Lara E Silva ),Vanessa C Rodrigues(Vanessa C Rodrigues ),Gisele R Vicente(Gisele R Vicente ),Marco Machado(Marco Machado ) 사피엔시아 2021 Exercise Medicine Vol.5 No.-

Objectives: Plyometrics has been used in sports training and many aspects of this modality are poorly understood. This study measures the magnitude of variations of serum creatine kinase (CK) activity and perceived muscle soreness after one session of Countermovement Jump (CMJ) session and compares 1 and 3 minutes rest intervals between each sets. Methods: A group of 30 young male was dividing in two groups and performed ten sets of ten CMJ with 1 or 3 minutes rest interval between sets. Before and after session (24, 48, and 72-h) they informed the muscle soreness perception and blood samples were collected for dosage of serum CK activity. Two (time) x Two (treatment) ANOVA was used to test differences in serum CK activity and muscle soreness. The alpha level was set at 0.05. Results: Serum CK activity measured 48 h after session augments ~2 and ~1.5 times in 1 min and 3 min rest interval respectively. No significant difference between groups that rests 1 or 3 minutes between sets was found. Muscle soreness rises 24 h after session without significant differences between groups. Conclusions: The findings show that the CMJ increases perceived muscle soreness and increases the serum CK activity, and the intervals of rest do not modulate these variables.
