Abstract

Papua is known as an island rich in plant diversity and potential fauna. The problems encountered are that not all types of genetic resources have been explored and identified, limited guidance on the characterization of local plants and some of them are also starting to be difficult to find, especially species that experience rarity and lead to extinction. This study aims to explore and introduce the potential of typical Papuan fruit plants so that it is useful for policymakers for the development of typical fruit plants in the future as a food reserve source of vitamins, and minerals. The location was determined based on where typical fruit plants grow in Papua Province. Data collected include socio-cultural data (local wisdom), its contribution to the economy of farmer households, and growing environment data. The research method used was descriptive exploration, to be able to document community knowledge about the management of typical fruit germplasm requires appropriate information gathering and careful and in-depth study. Information was taken in the yard and land outside the yard/farmer's garden. Activities were carried out from March to December 2019 in Jayapura district. Local plants include fruit plants endemic to the local community, which have been used for generations by the local community.

Abstract

Catharanthus roseus (L.) G. Don contain bioactive compounds that act as inhibitors against the α-glucosidase enzyme. This study aims to test the α-glucosidase enzyme inhibitor activity of fermented extract of endophytic bacteria from tapak dara leaves and identify the bacterial species. Endophytic bacteria were isolated using a direct planting method, resulting in eight isolates. The bacteria were fermented for 24-72 hours in nutrient broth media. Ethyl acetate was used to extract the fermented bacteria. Screening for α-glucosidase enzyme inhibitory activity was conducted using the TLC bioautography method. Four bacterial isolates (TD 1, TD 3, TD 4, TD 7) produced clear zones, qualitatively indicating that the isolates have inhibitory activity against the α-glucosidase enzyme. The IC50 results from the eight isolates showed that three isolates provided strong IC50 values: isolate TD 1 at 19.93 µg/ml, isolate TD 2 at 92.34 µg/ml, and isolate TD 4 at 13.94 µg/ml, compared to acarbose at 48.85 µg/ml). Molecular identification showed that isolate TD 1 was Pseudomonas oryzihabitans and isolate TD 4 was Staphylococcus warneri. This study concluded that endophytic bacteria from tapak dara leaves have the potential as a source of α-glucosidase enzyme inhibitor compounds for the development of antidiabetic drugs.

Abstract

Mastery of arithmetic operations is fundamental for students pursuing science education, as these skills are essential in solving complex problems in physics, chemistry, and biology. However, gaps in students' arithmetic proficiency can hinder their academic and professional development. This study aims to examine the arithmetic skills of pre-service science teachers in solving mathematical problems across six domains: addition, subtraction, multiplication, division, exponentiation, and mixed operations. A total of 37 short-answer questions were administered, and the results were analyzed by domain. The findings indicate that students demonstrate proficiency in basic operations involving whole numbers, particularly in addition and subtraction. However, challenges persist in the areas of fractions, decimals, and mixed operations, where accuracy rates were notably lower. These gaps in understanding may affect students' ability to apply mathematical concepts in their science courses and future teaching roles. The study's limitations include a focus on quantitative results without exploring the cognitive processes behind student errors. Future research should investigate intervention strategies to address these weaknesses, potentially through targeted instructional approaches or the use of technology to enhance learning outcomes

Abstract

Tin mining tailings consist of 80-90% sand and the rest mud.  The high levels of Silicon Dioxide (SiO2) in these tailings are hard and can be used as an added material in the manufacture of composites.  This research aims to study the physical and mechanical properties of metal matrix composites reinforced with SiO2 powder processed by powder metallurgy, as an effort to provide a replacement material for Non-Asbestos (NOB) motorbike brake linings.  The impact of hot compaction pressure in the form of two pressing directions, including 4600, 4500 and 4400 Psi, with a pressing hold of 15 minutes and sintering which includes 30, 20 and 10 minutes, at a temperature of 600 ºC was studied for its effect on hardness and density.  Mechanical blending was used with a horizontal ball mill in the ratio of 10:1 at a speed of 90 rpm for 4 hours.  The test results showed that the greater the hot compaction pressure and the longer the sintering, the higher the hardness and density values.  The highest hardness reached 81.7 HB and the highest density of 2.385 g/cm3 occurred at a bidirectional hot compaction pressure of 4600 Psi, with the lowest wear rate of 0.333 mm3/m. This occurs as a result of the increase in hot compaction has an impact on increasing the contact between powder particles resulting from mechanical alloying to be tighter as a result of which the cavity and porosity decrease

Abstract

Orthosiphon aristatus (Blume) Miq., commonly known as kumis kucing, is frequently used in traditional Indonesian medicine to treat diabetes, hypertension, rheumatism, gout, and as a diuretic. However, large-scale production of medicinal products from natural sources requires significant raw material and land, creating a need for alternative methods. This study explores the potential of isolating endophytic bacteria from kumis kucing leaves to serve as α-glucosidase enzyme inhibitors, offering a more sustainable approach. Eight bacterial endophytes were isolated and tested using bioautography assays and IC50 measurements to assess their inhibitory activity. Four isolates—KK 1, KK 3, KK 4, and KK 5—demonstrated significant α-glucosidase inhibition, with IC50 values of 41.35 µg/mL, 57.04 µg/mL, 56.70 µg/mL, and 164.16 µg/mL, respectively. Molecular testing identified KK 1 as Priestia aryabhattai, while KK 3 and KK 5 were identified as Priestia megaterium. These findings suggest that endophytic bacteria isolated from Orthosiphon aristatus leaves have the potential to be developed as natural sources of α-glucosidase inhibitors, which are beneficial for diabetes management.
