Abstract

Bio-baterai menawarkan solusi potensial sebagai alternatif baterai konvensional yang tidak ramah lingkungan dengan memanfaatkan bahan-bahan organik dan mudah didapat, seperti serbuk kulit udang dan air laut. Tujuan penelitian ini adalah menentukan komposisi optimum serbuk kulit udang dan air laut yang menghasilkan arus dan tegangan maksimum. Lembaran gafit digunakan sebagai anoda dan lembaran aluminium sebagai katoda. Serbuk kulit udang dengan variasi massa 2-10 g dilarutkan dalam 20 ml air mineral (Aqua) menggunakan magnetic stirrer selama 10 menit, kemudian ditambah 35 g tepung tapioka secara bertahap hingga membentuk elektrolit padat. Elektrolit ini ditempatkan di antara lembaran gafit dan aluminium. Komposisi optimum serbuk kulit udang dikombinasikan dengan air laut (1-5 ml) untuk meningkatkan arus dan tegangan. Hasil menunjukkan bahwa bio-baterai yang hanya menggunakan larutan serbuk kulit udang menghasilkan arus maksimum 0,68 mA dan tegangan 0,803 V dengan massa optimum 6 g. Kombinasi serbuk kulit udang dan air laut menghasilkan arus 2,02 mA dan tegangan 0,858 V dengan volume optimum 3 ml air laut. Penelitian ini menunjukkan potensi besar untuk pengembangan lebih lanjut karena metodenya sederhana dan bahan yang digunakan murah serta ramah lingkungan.

Abstract

Increased production in industries tends to increase burden and complexity of waste produced. For this reason, it was necessary to develop materials that have good degradation capabilities and into environmental products. In this research, the MnO2 has been synthesized using the strategy of coprecipitation and reducing agents. The as-synthesized MnO2 is then used for the degradation of methylene blue. The results of this study indicate that different strategy of coprecipitation and reducing agents produce different MnO2 and has unique properties as nano-hierarchical microstructure. Using citric acid as a reducing agent results in a hierarchical structure of α-MnO2 and Mn2O3, while oxalic acid produces a hierarchical structure of β-MnO2 and Mn2O3. To optimize the degradation of Palm Oil Mill Waste which contains a high concentration of pollutants, it still needs to be improved. From the parameters pH, chemical oxygen demand, oil & grease, and total suspended solids, the best degradation efficiency of each parameter was achieved at pH 8.8, 16.3%, 43.5% and 56.6%.

Abstract

Local wisdom in Gayo society has been passed down from generation to generation, two of which are Sumang and Didong. Sumang is a cultural system that has roots in the Gayo people as an archetype and foundation of life. Meanwhile, Didong is a local art from the Gayo area that combines vocal, dance and literature. This research uses a type of qualitative research with a descriptive approach, which aims to preserve and restore the implementation of Sumang and Didong, as well as to describe the acceptance of the Gayo Highlands community towards the idea of ​​implementing Sumang values ​​into Didong art in order to achieve a society with character. All formal and non-formal art galleries and the Ceh Didong in the Gayo Highlands became the population in this study, with the sample being the Renggali Studio and 3 Cehs. Data collection techniques using observation and interviews. Research data were analyzed using descriptive data analysis techniques from observations and interviews. The results of the study show that: (1) the people of Gayo Highlands agree with the idea of ​​applying Sumang values ​​to Didong art, and (2) the role of the younger generation through actual practice of applying Sumang values ​​in their activities and exemplifying the application of Sumang values ​​to in Didong art without changing the characteristics of Didong art.

Abstract

This study explores mathematical ontology, an interdisciplinary field aimed at understanding the nature of the existence of mathematical concepts. Mathematics is a universal language that plays a crucial role in various disciplines. However, the complexity and abstraction of mathematical concepts often make their understanding and application challenging. This research employs a qualitative literature review method to investigate the development of thought and debates in mathematical ontology. The results of the literature analysis reveal the complexity of mathematical concepts and efforts to detail and organize mathematical ontology. This study identifies the significance of mathematical ontology in understanding mathematics, developing mathematical applications, and teaching mathematics. The research provides a deeper understanding of mathematical concepts and the fundamental structure of mathematical ontology, highlighting the potential for developing mathematical ontology in both pure and applied mathematics. The findings underscore the relevance and urgency of understanding mathematical ontology in the context of a rapidly advancing scientific and technological landscape. In conclusion, mathematical ontology serves as a crucial tool in the development of mathematics, and a deeper understanding of mathematical concepts and their ontology plays a vital role in the application of mathematics across various scientific disciplines and daily life.

Abstract

Various manganese oxides have been reported to be an active catalyst for degradation of a dye. The synthetic manganese oxides can be conducted by several methods with the products having the different physicochemical properties and structures. This research focused on the synthesis of  hausmanite-type manganese oxide (Mn2O3)  by hydrothermal method with different mole  ratio  of  KMnO4/glucose (3:1 and 2:3) and its application as a Fenton catalyst   for the degradation of methylene blue (MB). The as-synthesized manganese oxides were then characterized  by XRD for their structure and crystallinity and FTIR and Raman spectroscopy for the lattice vibrations. The average oxide state (AOS) of manganese in the as-synthesized manganese oxide was determined by the back titration method. The XRD results indicated  the presence of mixed phases with hausmanite  phase as major component and  cryptomelane and birnessite phases as minor ones. FTIR spectroscopy results showed the presence of O-Mn vibrations at wavelengths of 468 cm-1, 487cm-1, and 726 cm-1. In addition, Raman spectroscopy results clearly showed the  specific vibrations of hausmanite at 655 cm-1 and 653 cm-1, respectively. The low value of  Mn AOS was obtained when the oxide was prepared in low ratio KMnO4/glucose and short reaction time. The as-synthesized hausmanite was  tested  as the Fenton catalyt for the degradation of MB.  The as-synthesized hausmanite synthesized with different mole rasio and reaction time showed similar catalytic activity for the degradation of MB with the highest MB degradation of 90.76%

Abstract

In Graph Theory, the concept of vertex coloring is an interesting topic because it can be implemented in various fields in everyday life. One of them is the distribution of dorm rooms at a school in Makassar. The placement of dorm rooms is made so that no students from the same class or region are in the same room. The data of region and class will be represented in an adjacency matrix with 137 rows and columns. Furthermore, the coloring will be solved by using the Welch-Powell algorithm. The coloring results obtained were 50 colors. That means, the rooms needed to place 137 students so that no one comes from the same region, and classes are 50 rooms with a maximum capacity of 4 people in each room.

Abstract

The main problems in the implementation of the e-Court system in the Religious Court are the limited information technology infrastructure, technical constraints, and low digital literacy of the parties to the case. This condition creates a gap between the goal of digitizing the judiciary and the reality of implementation in the field. This study aims to examine the implementation of the Supreme Court of the Republic of Indonesia Regulation Number 7 of 2022 concerning the administration of cases and electronic trials at the Religious Court under the jurisdiction of the Banten High Court of Religion. The method used is juridical-empirical with a qualitative approach, through data collection in the form of in-depth interviews and direct observation at six Religious Courts in the jurisdiction. The results of the study show that e-Court is able to improve the efficiency of administration and trial processes, but still faces obstacles in the form of limited infrastructure, lack of digital literacy of the parties, and lack of ongoing technical support. The contribution of this research lies in providing comprehensive strategy recommendations through strengthening infrastructure, increasing user capacity, and policy socialization so that the implementation of e-Court can be more equitable, effective, and support the realization of a fast, transparent, and fair judicial system.
