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

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.
