Abstract

The ability of Indonesian students to master physics is still low. Based on PISA in 2018, Indonesia ranked at 62th out of 72 participating countries. It was much lower than other Asian countries. Therefore, this problem should be overcome. One of the existing sources of physics literacy is local wisdom. The local wisdom can be used as a direct source of physics studies for students to increase their literacy skills. Therefore, in this paper, the authors discussed some local wisdoms in South Sumatra Province that potentially used as physics literacy objects for students in their school. South Sumatra has many local wisdoms potentially used as real objects in physics studies for students. Some of the local wisdom as otok-otok boat and roasted kemplang can be used as the object of heat transfer studies (thermal), and the traditional houses of Limas and Baghi can be used as media for learning force, mass, load and modulus of elasticity. The objects of literacy studies are sources of study that can be used by teachers in teaching physics. Through local wisdom-based literacy, it is certainly expected to improve Indonesia's PISA ranking. Not only to improve PISA ranking, but it is also increase the superiority of the nation's future generations.

Abstract

Endophytic fungi are fungi which live inside the host plant tissue and have been undergone a horizontal gene transfer process. Endophytic fungi are able to synthesize the same bioactive compounds which synthesized by their host plants. The host plant used in this research was dragon’s scales fern (Pyrrosia piloselloides (L.) M.G. Price). Dragon’s scales fern produces various of bioactive compounds which used as antibacterial agents such as polyphenols. This research was aimed to obtain endophytic fungi isolates from trophophyll fronds and sporophyll fronds of dragon’s scales fern, to determine the antibacterial activity of the secondary metabolite extracts of endophytic fungi, to determine the Minimum Inhibitory Concentration (MIC), to determine the characteristics of the endophytic fungi isolates which potentially as antibacterial source. Based on the research, 13 endophytic fungi isolates were obtained from dragon’s scales fern fronds consist of 5 isolates from trophophyll fronds and 8 isolates from sporophyll fronds. The antibacterial activity test showed that the extract of secondary metabolites of the isolate DTP2 had the highest inhibition zone diameter against E.coli 14.82 ± 4.05 mm, DTP4 against S.aureus 8.80 ± 0.03 mm and DSP4 against S.dysentriae 10.15 ± 0.36 mm. MIC of ethyl acetate extracts of secondary metabolites of isolate DTP2 against E.coli was 125 µg/mL, DTP4 against S.aureus was 125 µg/mL and DSP4 against S.dysentriae was 31.25 µg/mL. The endophytic fungi isolate DTP2 identified as Aureobasidium melanogenum, DTP4 identified as Penicillium alliisativi and DSP4 identified as Aspergillus flocculosus.

Abstract

South Sumatra, a province in Indonesia, is inhabited by several tribes. The geographical landscape surrounded by primary and secondary forests is a natural resource for the local communities in dealing with medical problems. They use plants as traditional medicine from generation to generation. The used parts include roots, stems, leaves, and sap that are biologically active to treat some diseases from moderate to deadly diseases. Based on literature studies, there are 250 plant species from 79 families processed by local communities in South Sumatra in some ethnobotanical activities. The dominant plant families are Fabaceae (5.6%), Asteraceae (4.8%), Euphorbiaceae (4.4%), Poaceae (4.4%), Myrtaceae (3.6%), Rubiaceae (3.6%), Rutaceae (3.6%), Solanaceae (3.6%), and Piperaceae (3.2%). Among many methods, boiling is the most common method in processing medicinal plants as it is considered more effective in extracting the bioactive compounds.

Abstract

In this article, the author discussed the inheritance system in Indonesia. The inheritance distribution system in Indonesia is based on Islamic law, civil code, and customary law. On the other hand, gender equality activists have their perspectives regarding the justice of the distribution system based on the proportion received by men and women. Based on the discussion, it was known that there are similarities and differences among Indonesian inheritance distribution systems. Each of the systems regulates that the testator must die and the main heirs are blood-related to the decedent. In Islam law, men receive more than a woman with a ratio of  2:1 due to men’s responsibility to their family. Meanwhile, the proportion between men and women regulated by the Indonesian civil code is equal. In Minangkabau matrilineal customary law, as a system based on the mother's lineage, the proportion of inheritance is distinguished between high inheritance and low inheritance. The high inheritance will be given to the woman and the low inheritance will be shared equally between men and women. However, some gender equality activists might see those proportions as a form of injustice. But, each of the systems has its perspective regarding justice.

Abstract

As agricultural sectors rise due to increased human population, the demand for chemical fertilizer is also uplifted. However, the excessive use of chemical fertilizers reduces soil quality and natural properties. To address these issues, an alternative eco-friendly biofertilizer is needed. Here, we developed a liquid biofertilizer called ESSIK to substitute hazardous chemical fertilizers. It is made from environmentally friendly waste materials—including chicken feathers, egg shells, and fish scales—which are repurposed to provide vital nutrients for plant growth. Egg shells contain calcium useful in the synthesis of plant enzymes, fish scales contain calcium and phosphorus which play a role in accelerating fruit ripening, and chicken feathers contain high protein which can be a source of amino acids. These components were first fermented using effective microorganisms (EM4) to break down complex polymers into forms more readily absorbed by plants. The fermented biofertilizer was tested using mung bean (Vigna radiata) with concentrations of 0%, 5%, 10%, 20%, and 100%, and a positive control of 5% EM4. Based on the study, 20% was the best formulation to support the growth of mung bean (V. radiata) with a length of more than 41 cm, 16 leaves, and 9 stalks. Also, the leaf's length was approximately 6,6 cm, width 3,8 cm, with a healthy-green appearance. These findings suggest that it has significant potential as an eco-friendly and sustainable biofertilizer alternative to chemical fertilizers, promoting robust plant growth while contributing to waste recycling and environmental conservation for a better future.

Abstract

This study aims to evaluate and compare the effect of the composition of water hyacinth (Eichhornia crassipes) with a banana peel on the absorption coefficient value as a composite material for absorbing sound waves. The cellulose within the water hyacinth and banana peel lead to reduced overload sound waves. This study used an experimental method providing banana peel crushed into powder, water hyacinth fiber, and resin (as a catalyst). All samples were prepared with dimensions of 13.5 cm × 25 cm × 0.8 cm. A frequency generator application was used as the sound source (125, 250, 500, 1000, and 2000 Hz), while a sound meter application measured sound intensity (dB). The results indicated that the outer surface of sample D had a superior absorption coefficient, measuring 0.51 at 250 Hz and 0.45 at 2000 Hz. Meanwhile, the inner surface of sample D recorded absorption coefficients of 0.46 at 250 Hz and 0.45 at 2000 Hz. Variations in absorption values were attributed to destructive interference and saturation. Sample D contained more water hyacinth (approximately 30%) than banana peel powder. This suggests that water hyacinth and banana peel powder are viable natural fiber alternatives for sound wave absorption.
