Abstract

This research have focused on isolation and identification of lactic acidbacteria (LAB) with potential antifungal which candidate as biopreservativemicroorganisms. LAB produce bioactive compound with antifungal activity. Thus, of atotal of 69 lactic acid bacteria isolated and 39 isolates further tested its antifungalactivity. Indigenous moulds that will be tested for antifungal activity of LAB wereobtained from unfermented cocoa beans. There were black mould (allegedly Aspergillusniger), green mould (allegedly Aspergillus fumigatus) and grayish white mold (allegedly Mucorspp.). Thus, 18 isolates of LAB that could inhibit all of three types of fungi further identified in aphenotype, 3 isolates of LAB with highest antifungal activity in identification with API 50 CHLmethod and identified as Lactobacillus fermentum, with a different value of ID value, ID99,8% (F1L-6an) criteria : very good identification; ID 99.9% (F1L-6dsr), criteria : verygood identification , and ID 89.8% (F3L-7P) criteria : very good identification to the genus .LAB isolates obtained can be used as starter cultures to improve the quality offermentation to inhibit the growth of mould, mycotoxin production, and fungicideresidues so as to improve quality, safety of cocoa concumption, and increase the priceof Indonesian cocoa bean exports.

Abstract

The purpose of this study is to investigate the hypocholesterolemic activity of kedawung (Parkia roxburghii), an underutilized and lesss-known tree nut. Kedawung was prepared into kedawung powder (BK), kedawung extract (SK) and hydrolyzed kedawung (HK) and then analyzed for its proximate and total phenol content. Furthermore, SK and HK were administered to rats to evaluate their effects on the lipid profile. Oral administration of HK at 160 mg/kg body weight increased the HDL cholesterol level and lowered the LDL and total cholesterol levels in blood of the administered rats. Among groups of the administered rats that completed the 35-day treatment, total cholesterol and LDL cholesterol were significantly reduced (p0.01). The present data showed that kedawung has a hypocholesterolemic activity because of its phenolic content that acts as antioxidant that can bind cholesterol in blood; composition and distribution of amino acid in HK that changed the cholesterol metabolism (reduced cholesterol concentration); protein content in HK that increased the production of lipoprotein that plays a role in suppression of plaque and atherosclerosis. Therefore, hydrolyzed kedawung can be used as an hypocholesterolemic food material.

Abstract

Introduction: Indonesia is in an aging population era marked by an increase in elderly population above 7%. An enhancement of elderly population presents health problems due to organ function deterioration and requires extraordinary attention. General health, nutrition, and oral health status are the most problems claimed by elderly, particularly retired. Objective of this study was to analyze the correlation between the general health, nutrition, and oral health status of elderly. Methods: Analytical descriptive research with cross sectional method was carried out on 36 respondents in Paguyuban Purnabakti, Patrang, Jember, East Java Province. The sampling was done by purposive sampling. Information about social-demography and general health status of respondents were obtained from the questionnaire. The social-demography investigation comprised sex, age, education level and status of residence. While general health observation, it comprised smoking status, general check-up, presence of systemic diseases, blood pressure and blood biochemical parameters.[CS1]  Nutritional status was examined by body mass index (BMI). Oral examination for identifying oral health status included the number of the teeth remaining in the oral cavity, use of dentures, oral hygiene index (OHI-s), and periodontal tissue health (CPITN). Results: The result exhibited that most of the respondents presented good general health status. However, there was no significant correlation between routine general health observation and age (p=0.906). Moreover, there was no significant relationship between blood biochemical profile (blood glucose, total cholesterol, and blood pressure level) with nutrition status (p=..., p=..., and p=... respectively), and oral health status (p=...), except with oral hygiene (p=...). Conclusion: This study is limited to Paguyuban Purnabakti, Patrang, Jember, East Java Province. Although this study could not be generated in all communities, this study concluded no relationship between general health (smoking, systemic disorders, and routine general health observation), nutritional status, and oral health in the elderly. [CS1]Disesuaikan dengan table 2

Abstract

  This study aimed to analyze the relationship between gadget use intensity and learning concentration among upper-grade students at SD Negeri 1 Delod Peken. A quantitative approach with a correlational research design was employed. The population consisted of 82 students in Grades IV, V, and VI, all of whom were selected as research participants using a saturated sampling technique. Data were collected through Likert-scale questionnaires that had met validity and reliability requirements. Data analysis was conducted using descriptive and inferential statistics with the assistance of IBM SPSS Statistics version 25. Prior to hypothesis testing, normality and linearity tests were performed. The results revealed that the intensity of gadget use was categorized as moderate, with a mean score of 80.04, while students’ learning concentration was also in the moderate category, with a mean score of 70.74. Pearson Product-Moment correlation analysis showed a correlation coefficient of r = -0.543 with a significance value of 0.000 (p < 0.05). These findings indicate a significant negative relationship between gadget use intensity and learning concentration. In other words, higher levels of gadget use tend to be associated with lower levels of learning concentration, and vice versa. Furthermore, the coefficient of determination analysis indicated that gadget use intensity contributed 29.5% to students’ learning concentration, while the remaining 70.5% was influenced by other factors beyond the scope of this study.The findings suggest that wise and controlled gadget use, supported by proper supervision from teachers and parents, is essential to maintaining and improving students’ learning concentration. Keywords: Gadget Use Intensity, Learning Concentration, Elementary School Students. ABSTRAK Penelitian ini bertujuan untuk menganalisis hubungan antara intensitas penggunaan gawai dan konsentrasi belajar siswa kelas tinggi di SD Negeri 1 Delod Peken. Penelitian menggunakan pendekatan kuantitatif dengan metode korelasional. Populasi penelitian berjumlah 82 siswa kelas IV, V, dan VI yang seluruhnya dijadikan sampel melalui teknik sampling jenuh. Pengumpulan data dilakukan menggunakan angket skala Likert yang telah memenuhi uji validitas dan reliabilitas. Data dianalisis menggunakan statistik deskriptif dan inferensial dengan bantuan IBM SPSS Statistics 25. Sebelum pengujian hipotesis, dilakukan uji normalitas dan uji linearitas. Hasil penelitian menunjukkan bahwa intensitas penggunaan gawai berada pada kategori sedang dengan nilai rata-rata 80,04, sedangkan konsentrasi belajar siswa juga berada pada kategori sedang dengan nilai rata-rata 70,74. Hasil uji korelasi Pearson Product Moment menunjukkan nilai koefisien korelasi sebesar r = -0,543 dengan nilai signifikansi 0,000 (p < 0,05). Temuan ini menunjukkan adanya hubungan negatif dan signifikan antara intensitas penggunaan gawai dan konsentrasi belajar siswa. Semakin tinggi intensitas penggunaan gawai, semakin rendah konsentrasi belajar siswa, dan sebaliknya. Hasil analisis koefisien determinasi menunjukkan bahwa intensitas penggunaan gawai memberikan kontribusi sebesar 29,5% terhadap konsentrasi belajar siswa, sedangkan 70,5% dipengaruhi oleh faktor lain di luar penelitian. Dengan demikian, penggunaan gawai perlu dikelola secara bijak melalui pengawasan dan pendampingan dari guru maupun orang tua agar tidak mengganggu konsentrasi belajar siswa. Kata Kunci: Intensitas Penggunaan Gawai, Konsentrasi Belajar, Siswa Sekolah Dasar.
