Abstract

Provinsi Jambi memiliki cadangan batubara sebesar ±18 juta ton, yang sebagian besarnya merupakan batubara kelas kalori sedang. Cadangan batubara yang besar berakibat terhadap banyaknya jumlah penambangan batubara terjadi. Penambangan batubara yang banyak tidak diseimbangi dengan pengelolaan terhadap lingkungan, yang berdampak terkontaminasinya tanah bekas tambang batubara oleh logam berat. Salah satu logam berat yang mencemari lahan bekas tambang batubara adalah Cr atau kromium. Logam Cr pada lahan bekas tambang biasanya ditemukan sekitar 1645 ppm sedangkan baku mutu logam berat Cr 2-5ppm. Untuk mengurangi kadar logam berat Cr dapat dilakukan dengan imobilisasi logam menggunakan low-cost sorbent (LCS) yang berasal dari barubara muda (lignite) pada metode batch experiment. Berdasarkan data yang diperoleh kandungan logam berat Cr diukur dengan spektroskopi serapan Atom (AAS), dengan neggunakan variasi biochar 0%, 5%,10%, dan 15% didapatkan imobilisasi optimal logam berat Cr pada variasi biochar 15% dimana logam yang terserap 0.0936mg/g.

Abstract

ABSTRACT POME wastewater treatment remains a significant area of research due to the industry’s large scale and high potential for wastewater pollution. This research investigated the effect of variations in contact time and surface area of Zinc (Zn) electrodes on the parameters of pH, COD, BOD, TSS, VSS, and oil and fat values in the POME wastewater. POME wastewater treatment was conducted using the EAPR method with an electric voltage of 9 (nine) volts and utilizing 3 (three) water hyacinth plants, each with 5–8 leaves. The treatment process was terminated once the reduction in pollutant concentration reached a constant number. The results showed that the values that met quality standards were pH values in all treatments and BOD values in the 45-minute contact time variation across all electrode surface areas. As for the other analysis values, they did not meet the quality standards, with the highest COD reduction of 91.46%, the highest TSS reduction of 96.77%, the highest VSS reduction of 24.92%, and the highest oil and fat reduction of 98.89% observed in the 75 minutes contact time variation using a cathode surface area of 500 cm2 and anode 14 cm2. It can be concluded that this method is currently ineffective for POME wastewater treatment as not all parameters meet quality standards. This research is expected to provide valuable insights for future experiments in wastewater treatment. Recommendations for further research include adding a method to increase oxygen levels in wastewater or adding microorganisms to enhance organic breakdown. ABSTRAK Penelitian mengenai pengolahan limbah cair industri minyak kelapa sawit terus dilakukan karena industri ini merupakan industri yang besar dan menghasilkan banyak limbah cair dengan potensi pencemaran yang tinggi. Penelitian ini bertujuan untuk menganalisis pengaruh waktu kontak dan luas permukaan elektroda seng (Zn) terhadap konsentrasi nilai pH, COD, BOD, TSS, VSS, serta minyak dan lemak. Pengolahan limbah cair pabrik kelapa sawit dilakukan dengan menggunakan metode EAPR bertegangan 9 volt dengan 3 tanaman eceng gondok berdaun 5–8 helai. Perlakuan dihentikan jika penurunan sudah mencapai angka yang konstan. Hasil penelitian menunjukkan bahwa nilai yang memenuhi baku mutu yaitu nilai pH pada seluruh perlakuan dan nilai BOD pada variasi waktu kontak 45 menit di seluruh variasi luas area permukaan elektroda. Sedangkan untuk nilai analisis yang lain masih belum sesuai dengan baku mutu, dengan penurunan COD tertinggi sebesar 91,46%, penurunan TSS tertinggi sebesar 96,77%, penurunan VSS tertinggi sebesar 24,92%, serta penurunan minyak dan lemak tertinggi sebesar 98,89% pada variasi waktu kontak 75 menit dengan luas permukaan katoda 500 cm2 dan anoda 14 cm2. Dapat disimpulkan bahwa metode ini belum efektif untuk pengolahan limbah cair pabrik kelapa sawit karena belum seluruh analisis memenuhi baku mutu. Penelitian ini diharapkan dapat bermanfaat untuk dikaji lebih lanjut untuk pengolahan limbah cair. Saran untuk penelitian selanjutnya yaitu menambahkan metode aerasi supaya dapat meningkatkan kandungan oksigen dalam air limbah atau menambahkan mikroorganisme untuk mengurai kandungan organik.

Abstract

Inovasi dan studi silika mesopori magnetik untuk penyangga imobilisasi enzim glukoamilase untuk hidrolisis pati kentang belum dilakukan karena penyangga magnetik hanya dikaitkan dengan bahan partikel nano baik murni maupun komposit. Proses imobilisasi enzim glukoamilase pada penyangga dengan kondisi operasi proses divariasikan untuk diketahui pengaruhnya terhadap proses dimana hasil akhir adalah tingkat imobilisasi enzim yang cukup besar yang disimpulkan dari hasil analisis kandungan protein (metode Bradford), FTIR dan SEM-EDX. Bahan partikel nano magnetik berhasil diinkorporasi pada permukaan silika MCF (9.2T-3D) dengan tingkat imobilisasi optimum enzim glukoamilase bebas adalah sekitar 89,46% yang didapatkan pada kondisi operasi optimum pH larutan buffer 5,0, suhu operasi 35°C, kecepatan pengadukan 120 rpm,dan konsentrasi enzim suplai sebesar 5,5%. Walaupun unit aktivitas enzim amylase amobil adalah lebih rendah daripada enzim amylase bebas, enzim amobil tetap dapat digunakan untuk menghidrolisis susbtrat larut dalam air. Poses hidrolisis pati kentang dengan enzim tersebut menghasilkan nilai DE optimum 26,93% pada suhu 70°C, kecepatan pengadukan 170 rpm, pH buffer asetat 0,1 M 4,6, dan konsentrasi enzim 1500 U/mg.

Abstract

This research discusses the importance of moderation and religious tolerance between religious communities in Indonesia, which is known for being rich in religious and cultural diversity. In the context of globalization, religious and cultural pluralism is quite a big challenge, where differences in beliefs can trigger tension and conflict if not managed well. Therefore, a religious moderation approach is proposed as a solution to overcome these differences constructively and harmoniously. The aim of this research is to explore how religious moderation can contribute to social harmony and the development of an inclusive society. This research also emphasizes the importance of tolerance as a basis for maintaining social peace, where every individual is recognized and recognized for their rights to carry out their religious beliefs. The methodology used in this research includes qualitative analysis of religious moderation practices in various communities, including in Cisantana Village, which is a clear example of how inter-religious harmony can be realized amidst diversity. The research results show that implementing an attitude of religious tolerance and moderation not only increases social unity, but also prevents conflicts that may arise due to differences in beliefs. By engaging in education, interfaith dialogue, and policies that support religious freedom, society can build mutual respect and understanding. The conclusion of this research confirms that moderation and religious tolerance are the keys to creating social harmony and preventing conflict in a multicultural society like Indonesia, as well as the importance of the active role of government and organizations in supporting these initiatives

Abstract

Biomaterials is an advanced material engineering technology that is used to help heal bone fractures or fractures. Currently, many biomaterials use materials such as titanium alloy, stainless steel, platinum, and chromium, but these materials cannot be degraded naturally so a second operation must be carried out to remove the installed biomaterial. Biomaterials are temporary in nature so when the bone returns to its original state, the biomaterial must be surgically removed. Research was conducted to obtain a design with a material that can be naturally degraded without causing toxicity. Magnesium AZ31B is a recommended candidate as a base material for degradable bone implants. Magnesium AZ31B material, it is expected to reduce or minimize the surgical removal of implant biomaterials. Bone plate geometry  use plate  bone  dimension 150mm x 15mm x 3mm with  variation 10 hole parallel and zigzag as well as with a bolt  bone  dimensions  long 40 mm with pitch 1mm diameter 5mm. Test bending was conducted  with ASTM E290-14 showing  that on plate  bone  hole parallel  with  burden  maximum 33,419 KN with a deformation  maximum of 30.89 mm whereas  for  plate  bone  hole zig zag with the burden  maximum 32,863 KN with  deformation  maximum big as 29.97 mm. From the study  experimental  that  plate  bone  hole  parallel  have  nature  mechanic  more  tall  compared  with  plate  bone  hole zig Zag although  with the difference which is not significant. Whereas on simulation FEA plate bone  hole  parallel  with  burden 33,419 KN get  results total deformation  as big as 31,481 mm with von Mises stress 15,337 MPa, then  for  plate  bone  hole zig Zag with  burden 32,863 KN with total deformation 32.466 mm and von Mises stress as big as 33,948 MPa. In testing by  experiment and simulation FEA plate  bone  hole  parallel  get  difference  around 0.591 mm or 0.94% whereas  for  plate  bone  hole zig Zag in  testing  by  experiment and simulation  get  difference  around 2,893 mm or 4.60%.

Abstract

Farmers' knowledge about soil ecology, which is a key factor in increasing the productivity of agricultural products, needs to be evaluated considering that various counseling efforts to increase agricultural yields have not shown satisfactory results. Farmers still unequally manage farmland, providing excessive chemical fertilizers without regard to soil ecology. The purpose of this education is to evaluate the knowledge of the Women's Farmers Group (WFG) before and after conducting soil ecology education based on Islamic science. The subjects of this education were 15 members of WFG Bunga Padi, Jorong Kawai, Nagari Batu Bulek, Lintau Buo Utara, Tanah Datar, West Sumatra, Indonesia. The community-based research (CBR) approach is used in this educational activity. The stages of educational activities start from socialization, laying the basis of the research and the research design, providing pretests and materials, gathering information and analyzing data on biological factors, capillarity of groundwater, water holding capacity, soil aeration, soil fertility, and soil pH, and the evaluation (post-test). The results show an increase in knowledge and understanding among WFG Bunga Padi members after Islamic science-based soil ecology education. It is hoped that, over time, their mindset in managing farmland will be balanced, with less reliance on chemical fertilizers and more emphasis on soil ecology. As a result, Islamic science-based soil ecology education could have a role in improving farmland and laying the foundation for organic farming.
