Abstract

Ketergantungan akan pemakaian bahan bakar fosil yang terus meningkat telah mengubah pola pikir manusia untuk mengembangkan penelitian terkait energi alternatif terbarukan. Bioetanol yang berasal dari hasil fermentasi nira tanaman aren (Arenga pinnata MERR), dan dikenal sebagai minuman tradisional Moke di Flores dapat dimanfaatkan sebagai bahan bakar alternatif jika memiliki kemurnian di atas 99,5%. Proses adsorpsi merupakan salah satu metode yang dilakukan untuk menghasilkan bioetanol dengan kadar di atas titik azeotrop. Adsorben yang efektif digunakan sebagai molecular sieve adalah zeolit alam yang berasal dari kabupaten Ende – NTT. Peningkatan efisiensi penyerapan zeolit alam dalam pemurnian bioetanol berbahan baku Moke sudah dilakukan melalui proses aktivasi kimia. Penelitian ini bertujuan untuk mengetahui kadar dan kualitas bioetanol setelah pemurnian menggunakan adsorben zeolit alam Ende – NTT yang telah diaktivasi NaOH pada berbagai konsentrasi. Kadar bioetanol yang terdapat pada Moke sebelum dan sesudah proses adsorpsi ditentukan dengan instrumen gas kromatografi, karakterisasi zeolit alam menggunakan X-Ray Diffraction (XRD) dan Scanning Electron Microscope (SEM). Zeolit alam Ende dapat digunakan sebagai adsorben dalam meningkatkan kadar bioetanol berbahan baku Moke. The reliance on increasing use of fossil fuels has changed the human mindset to develop research related to renewable alternative energy. Bioethanol derived from fermented palm sugar sap (Arenga pinnata MERR), and known as Moke, traditional drink in Flores can be used as an alternative fuel if it has a purity above 99.5%. The adsorption process is one method used to produce bioethanol with a level above the azeotrope point. The effective adsorbent used as molecular sieve is natural zeolite originating from Ende - NTT. Increased efficiency of absorption of natural zeolite in bioethanol purification made from Moke has been done through a chemical activation process. This study aims to determine the level and quality of bioethanol after purification using Ende-NTT natural zeolite adsorbent which has been activated by NaOH at various concentrations. Bioethanol levels found in the Moke before and after the adsorption process were determined by gas chromatography instruments, natural zeolite characterization using X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). Ende natural zeolite can be used as an adsorbent to increase the level of bioethanol made from Moke.

Abstract

ABSTRAK: Kerang darah (Anadara granosa) merupakan sumber daya alam potensial di pulau Lembata provinsi Nusa Tenggara Timur. Penangkapan kerang darah yang berlangsung sepanjang tahun menghasilkan dampak negatif berupa limbah cangkang yang belum dikelola secara maksimal. Cangkang kerang darah mengandung kalsium tinggi yang berpotensi untuk dimanfaatkan sebagai prekursor kalsium dalam sintesis hidroksiapatit (HAp). Kandungan kalisum dalam cangkang spesies ini mencapai 44,57%. Metode yang digunakan dalam sintesis HAp ini ialah metode presipitasi, dengan mereaksikan Ca(OH)2 dari sampel cangkang kerang darah dan (NH4)2HPO4 sebagai sumber prekursor fosfat. Berdasarkan hasil spektrum difraksi sinar–X, kristalinitas HAp yang diperoleh sebesar 90,15%. Dari analisis gugus fungsi menggunakan spektrum inframerah transformasi Fourier diperoleh gugus fungsi OH-, PO43-, dan CO32- dalam senyawa HAp. Analisis berdasarkan mikroskop elektron pemayaran menunjukkan bahwa HAp memiliki bentuk bulat yang seragam. ABSTRACT: Blood clam (Anadara granosa) is a potential natural resource on Lembata Island, East Nusa Tenggara province. Catching blood clams that take place throughout the year has a negative impact in the form of shell waste that has not been managed optimally. Blood clam shells contain high calcium which has the potential to be utilized as a calcium precursor in the synthesis of hydroxyapatite (HAp). The calcium content in the shells of this species reaches 44.57%. The method used in the synthesis of HAp is the precipitation method, by reacting Ca(OH)2 from shell samples blood clam and (NH4)2HPO4 as a source of phosphate precursor.Based on the results of the X-ray diffraction spectrum, the crystallinity of the HAp obtained was 90.15%. From the functional group analysis using the Fourier transform infrared spectrum, the functional groups OH-, PO43-, and CO32- were obtained in HAp compounds. Analysis based on scanning electron microscopy showed that HAp has a uniform spherical shape.

Abstract

Waste from the textile industry is considered as a potential source of environmental pollution, especially water because it contains dangerous dyes. In this research, natural zeolite is used as an effective and efficient alternative adsorbent to overcome pollution caused by methylene blue and methyl orange dyes. Activation of natural zeolite was carried out with 3 M HCl solution and was characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). While the methylene blue and methyl orange adsorption processes were studied in variations in the weight of the adsorbent, contact time, and pH. The concentration of dyes left in the solution was observed with Spectrophotometer UV-Vis. The results showed that the adsorption capacity of natural zeolite in absorbing methylene blue was 21.189 mg/g and methyl orange was 18.208 mg/g. The optimum conditions of methylene blue and methyl orange adsorption are achieved with successive adsorbent weights 0.3 g and 0,4 g, successive contact times are 60 minutes and 90 minutes, and successive pH are 6 and 2 respectively. The adsorbent weight factor, contact time, and pH have an effect on the adsorption of methylene blue and methyl orange by natural zeolite from Ende.

Abstract

Ibuprofen is a type of anti-inflammatory drug. However, its use faces challenges in the medical field due to its rapid degradation, low bioavailability, limited solubility, and high permeability. One approach to address these issues is the encapsulation of ibuprofen by coating it with Montmorillonite (MMT) and Chitosan (CS) to control the released dosages of Ibuprofen. MMT and CS were used to coat ibuprofen using four methods. These methods were compared through dispersing MMT in water, mixing with chitosan, and combining ibuprofen under different conditions. Subsequently, tests were conducted on ibuprofen coated with MMT-CS, including morphology, efficiency, and release profile. The most effective method for controlling ibuprofen release was shown in the third method, where MMT-CS was first modified, and then ibuprofen was added to the modified MMT-CS. This method showed the highest encapsulation efficiency of 61.51%, the best release profile with 21.59% ibuprofen release within 90 minutes, and the most uniform encapsulation morphology. These studies indicated that the MMT-CS biocomposite effectively improves ibuprofen release efficiency, potentially enhancing therapeutic outcomes while reducing side effects of ibuprofen.
