Abstract

Bioelectrochemical Systems (BES) technology is a method for generating electric energy using bacteria as catalysts. The electricity is produced by Microbial Fuel Cells (MFCs), which represent the latest development in biological energy research. This study utilized substrates from banana stems and the bacterium Pseudomonas sp. The research aims to assess the potential of banana stems as a substrate in the MFC system and to determine the effects of adding a combination of an electrolyte solution and an appropriate buffering material to achieve maximum current, potential difference, and power density values. The results showed that the maximum current and potential difference achieved were 1.05 mA and 0.62 V, respectively, with a power density value of 446 mW/m². When combining the KMnO4 electrolyte solution with sodium phosphate buffer, a potential difference of 0.76 V and a current of 1.75 mA were obtained, resulting in a power density value of 911 mW/m². By using the K3[Fe(CN)6] electrolyte solution buffer with potassium phosphate buffer, a current of 1.14 mA was produced, and the power density value reached 406 mW/m².

Abstract

Ekstraksi minyak daun kemangi menggunakan metode Microwave Assisted Hydrodistillation (MAHD) telah dilakukan. Penelitian ini bertujuan untuk mengetahui daya dan waktu yang baik yang diperlukan untuk mengekstraksi minyak daun kemangi sehingga rendemen yang tinggi dihasilkan. Proses ekstraksi dilakukan menggunakan metode MAHD dengan pelarut air dan daya (400, 500, dan 600 W) serta waktu (30, 45, dan 60 menit). Karakterisasi minyak atsiri meliputi identifikasi warna, berat jenis, indeks bias dan kelarutan dalam alkohol 80% dan analisis GC-MS. Hasil yang diperoleh pada penelitian ini rendemen tertinggi minyak kemangi dengan metode MAHD sebesar 1.16% dengan daya 500 W selama 45 menit. Minyak kemangi yang dihasilkan berwarna kuning dengan indeksbias 1.48 dan berat jenis 0.95 g/m3. Minyak ini tampak keruh ketika dilarutkan dalam etanol sehingga diduga minyak atsiri yang diekstrak ini belum terlalu murni. Hasil analisis GC-MS dengan waktu retensi 30 menit menunjukkan bahwa minyak kemangi mengandung senyawa sitral (46.19%); neral (55.97%); geraniol (2.99%); geranil asetat (0.78%); dan linalool (0.76%). Dengan demikian, ekstraksi dengan metode ini sangat perlu dikembangkan agar kualitas minyak atsiri yang diperoleh lebih baik lagi.

Abstract

High egg consumption in Indonesia, particularly in South Sulawesi, presents a significant opportunity to utilize eggshells as precursors for hydroxyapatite. This study aims to characterize hydroxyapatite derived from chicken eggshells and to evaluate the absorption properties of chitosan-hydroxyapatite composites for methylene blue removal. The precipitation method was used for hydroxyapatite synthesis, as it produces hydroxyapatite with a high level of purity and low contamination. X-ray diffraction (XRD) analysis revealed that eggshells contain approximately 30% CaCO₃. The XRD diffractogram of hydroxyapatite from eggshells showed a peak at 2θ = 31.94º. Fourier-transform infrared (FTIR) spectroscopy identified key functional groups in hydroxyapatite, including hydroxyl (-OH) at 3434 cm⁻¹, carbonate (-CO₃²⁻) at 1421 cm⁻¹, phosphate bending (-PO₄³⁻) at 565 cm⁻¹, and phosphate stretching (-PO₄³⁻) at 1035 cm⁻¹. The chitosan-hydroxyapatite (Cs-HAp) composite showed the incorporation of chitosan functional groups, including amine (-NH) at 1577 cm⁻¹ and methylene (-CH) at 2928 cm⁻¹. The chitosan-hydroxyapatite composite demonstrated effective removal of methylene blue dye, with an absorption efficiency of 96% at a Cs-HAp ratio of 2:2 within 180 minutes. Based on the high adsorption efficiency, the chitosan-hydroxyapatite composite shows great potential for absorbing methylene blue.

Abstract

Purebred chicken eggshell is a promising natural source because it contains high calcium carbonate (CaCO3), which is used as a hydroxyapatite (HAp) precursor, with natural abundance and biodegradability, making it an eco-friendly alternative to synthetic materials. HAp is relevant for dye removal because of its high adsorption capacity, chemical stability, and ability to interact with dye molecules through ion exchange and surface interactions with the material. The composite adsorbent of Hap-zeolite is effective for wastewater treatment based on the result of HAp-zeolite composite's adsorption capacity against methylene blue. Methylene blue is one of the dyeing wastes originating from the textile industry. The method of synthesis of Hap used precipitation. The FTIR characterization results showed OH groups at wavenumber 3434 cm-1, CO32- group with wavenumber 1421 cm-1, PO43- bending group with wavenumber 565 cm-1, and PO43- stretching at wavenumber 1035 cm-1. The highest peak XRD yield at an angle of 2θ=34.04º corresponds to a hexagonal crystal formed. The adsorption process is carried out with a HAp-zeolite mass ratio of 4:2 (w/w), with contact times for 180 minutes, resulting in the best adsorption efficiency around 99.99% measured via UV-Vis spectrophotometry. The results indicate that HAp-zeolite composites are highly effective for methylene blue removal and have potential application in wastewater treatment.
