Albuminuria adalah kondisi adanya albumin pada urin. Adanya albumin dapat menjadi indikator penyakit ginjal dan kardiovaskular. Albumin dapat dideteksi berdasarkan perubahan warna biru menjadi kecoklatan menggunakan sensor perak iodida – metilen biru. Tujuan dari pengembangan tes cepat ini adalah mendeteksi albuminuria pada urin dengan memanfaatkan reagen perak iodida (AgI) dan metilen biru. Sensor kimia yang dikembangkan merupakan sensor kolorimetri yang terimobilisasi kertas dan dideteksi dengan metode scannometri. Analisis perubahan warna sensor untuk albumin pada penelitian ini menggunakan perangkat lunak imageJ. Sensor albumin berbasis perak iodida - metilen biru yang diusulkan memiliki waktu respon 7 menit dengan rentang linier 200 hingga 500 ppm dan batas deteksi adalah 83,039 ppm batas kualifikasi. Sensor memiliki reprodusibilitas (RSD = 2,6917%) dengan waktu pakai lebih dari 5 bulan dengan nilai akurasi 100,662%. Kata kunci: albuminuria, sensor kimia, tes cepat. ABSTRACT Albuminuria is a condition of the presence of albumin in the urine. The presence of albumin can be an indicator of kidney and cardiovascular diseases. Albumin can be detected based on the change of color from blue to brownish using a silver iodide – methylene blue sensor. This rapid test was developed to detect albuminuria in the urine by utilizing silver iodide (AgI) and methylene blue reagents. The chemical sensor was a colorimetric sensor immobilized with paper and detected by scannometric methods. The analysis of the sensor color changes for albumin was carried out using ImageJ software. The proposed silver iodide - methylene blue-based albumin sensor had a response time of 7 minutes with a linear range from 200 to 500 ppm and the detection limit of 83,039 ppm qualification limit. The sensor had reproducibility (RSD = 2.6917%) with a service life of more than 5 months with an accuracy value of 100.662%. Keywords: albuminuria, chemical sensor, rapid test.

Abstract

Salah satu cara untuk meningkatkan daya saing daerah adalah melalui peningkatan nilai ekonomi produk lokal. Pemanfaatan potensi berupa sumber daya alam secara optimal akan memberikan dampak dalam memacu roda perekonomian di daerah tersebut. Desa Tegalweru yang terletak di Kota Malang, Jawa Timur kaya akan sumber alam seperti cabe, buah tomat, jeruk, dan pisang. Saat panen raya tiba, masyarakat telah memiliki tradisi untuk memanfaatkan dan mengolah hasil buminya sehingga bernilai jual lebih tinggi. Salah satu usaha yang saat ini dikembangkan adalah keripik pisang. Melalui kegiatan pengabdian masyarakat dengan pendanaan Ma Chung Abdimas Grant (MAG), tim pengabdi memilih kelompok pembuat keripik pisang ini sebagai mitra dalam kegiatan pengabdian pada masyarakat skim IbDM (Ipteks Bagi Desa Mitra). Dalam waktu delapan bulan tim bekerja untuk meningkatkan daya saing produk hasil keripik pisang melalui perbaikan kualitas produk, pengurusan ijin Pangan Industri Rumah Tangga (PIRT), dan strategi promosi.

Abstract

Chitosan is one of the naturally abundant, biodegradable, and low-cost adsorbent materials for metal adsorption purposes. In this work, we evaluated the application of chitosan materials derived from seafood wastes in Depok beach, Yogyakarta, for an effective recovery of the palladium(II) ions. First of all, the seafood wastes were treated to obtain chitin and then followed by the deacetylation process to produce chitosan material with a deacetylation degree of 78.42%. The chitosan material was characterized using Fourier transform infrared (FTIR) spectrophotometer. It was found that chitosan gave high adsorption percentage (90%) for palladium(II) ions due to the complexation with hydroxyl, amino and carbonyl functional groups. The palladium(II) adsorption onto chitosan material followed the pseudo-second-order (R2 = 0.9978) and Langmuir (R2 = 0.9979) models for kinetic and isotherm experiments, respectively, with a maximum adsorption capacity value of 0.70 mmol g-1. The palladium(II) ions could be easily desorbed in 90% percentage using 1.0 M HCl solution from metal-laden chitosan to regenerate the adsorbent material. The chitosan-based adsorbent material did not lose its adsorption capability after three consecutive cycles with no significant structural change as revealed from the FTIR data. These results showed the potential application of natural chitosan materials derived from seafood wastes for the effective recovery of palladium(II) ions.

Abstract

Peat is a wetland region in Indonesia with a very high water storage capacity. However, the amount of humic compounds obtained from the accumulation of organic substances in peat makes the water unable to be used for daily purposes. Peat water treatment with several methods has been carried out, such as coagulation, electrocoagulation, flocculation, and filtration. However, the result of clumping or filtering in such a way raises new environmental problems. One method which effective and efficient used in peat water treatment is photocatalytic. Several materials based-semiconductor was developed as a photocatalyst, another modification of photocatalyst is combining the adsorbent as a porous supporting photocatalyst which can improve its performance.

Abstract

The 4-nitrophenol reduction process is one of the slow methods. One way to increase the rate of 4-nitrophenol reduction reactions is to use a catalyst. In this study, the catalyst used was silver nanoparticles conjugated by black tea extract. The stages that have been carried out in research are the synthesis of conjugated silver nanoparticles of black tea extract, the determination of the kinetic profile of 4-nitrophenol reduction, and the study of the influence of inorganic anions on the reduction of 4-nitrophenol with the presence of silver nanoparticle catalysts. The presence of conjugated silver nanoparticles of black tea extract has been shown to increase the kinetics of the degradation reaction of 4-nitrophenol compounds to 85 times compared to without nanoparticles, by changing the value of the reaction rate constant from 0.00006 to 0.0051. The presence of inorganic anions provides information on the decrease in the rate of reduction reactions of 4-nitrophenol.

Abstract

Sunlight has been known to provide many benefits to human life. However, behind these benefits, there are some negative effects along with the destruction of the ozone layer and the environment on earth. One of them is exposure to ultraviolet (UV) rays which can cause several diseases such as skin cancer. One way to overcome this is by using sunscreen substances. In this study, dibenzalacetone immobilization on TiO2 has been carried out for anti-UV applications. Based on the test results using UV-Vis spectrometry, TiO2, and dibenzalacetone both have anti-UV properties with maximum peaks at wavelengths of 335 nm and 346 nm with absorbance values of 0.871 and 1.197. Immobilization of TiO2 with dibenzalacetone gives an absorbance with a value of 1.221 at a wavelength of 329. These results indicate that TiO2 immobilization with dibenzalacetone provides better anti-UV A properties than TiO2 because of the higher absorbance value.
