Abstract

Iron (III) (Fe (III)) is widely used in the industry such us water treatment, the sugar cane, the concrete industry and coal mining. Industrial activity using Fe(III) has potential impact to environmental pollution problems due to that industry produces Fe waste that one of hazardous waste. Fe content excess might toxic effect to human health and the environment. Zeolite as adsorbent has been evaluated extensively for Fe and other heavy metal. Sonication method has been widely developed in polymer preparation. The method is more effective in operation time because the reaction rate increased and also more efficient on the usage of chemical reagens. The optimization of reaction time, the ratio of Fe(III) with activated zeolite, the influence of pH, and temperature has been assessed for Fe(III) adsorption with an activated zeolite by sonication technique. The formation of Fe(III)-SCN complex assay was used for determination of Fe(III) adsorbed by the activated zeolite with using spectrophotometer. The results showed a relatively short operation time (15 minutes), at pH of 4, temperature of  30 °C with the ratio of 1:50 (weight/volume) for the activated zeolite and Fe(III).

Abstract

Astaxanthin merupakan senyawa turunan karotenoid xantofil yang sangat potensial dalam pengobatan kanker. Salah satu upaya meningkatkan aktivitas anti kanker dari astaxanthin adalah dengan menggabungkan senyawa astaxanthin dengan ion logam. Upaya sintesis senyawa koordinasi astaxanthin dengan ion logam Fe3+, Mn2+, dan Zn2+ telah dilakukan dengan bantuan gelombang ultrasonik. Panjang gelombang maksimal senyawa kompleks Mn(II)-Astaxanthin adalah 473 nm, Fe(III)-Astaxanthin adalah 355 nm, dan Zn(II)-Astaxanthin adalah 473 nm. Hasil FTIR menunjukan munculnya gugus fungsi khas astaxanthin pada semua kompleks dan munculnya serapan pada 535 cm-1, untuk kompleks Mn(II)-Astaxanthin, 397 cm-1 untuk Fe(III)-Astaxanthin, dan 535 cm-1 untuk Zn(II)-Astaxanthin yang mengindikasikan adanya ikatan logam dengan atom donor dari Astaxanthin.

Abstract

Botanicals were known as active ingredients in sunscreens due to their dermal protecting. Gold in colloidal form has a completely unique property for the reason that it may be used as photoaging material. The exposure of UV radiation to skin can cause erythema and skin cancer. The aim of this study was to determine the physical properties of the sunscreens made from Au/ZnO and antioxidant from Moringa oleifera extract such as the sun protection factor (SPF), pH, spreadability, and adhesion. The Moringa oleifera were extracted by maceration. Maceration with 70% ethanol of dried leaves exhibited DPPH scavenging activity (EC50 235.01 μg/mL). Diffuse reflectance UV-Vis spectra of ZnO and Au/ZnO revealed absorption at λex of 385 nm which were equivalent to a bandgap energy of 3.22 eV. Au/ZnO posed a localized state at λex of 385 (3.65 eV). The sunscreens with formulations F1, F2, F3, and F4 showed high SPF number of 20.1479, 21.0008, 22.3872, and18.4631. Kruskal-Wallis test showed significant differences between sunscreen formulations.

Abstract

Desa Gondowangi adalah salah satu desa yang sebagian penduduknya mengandalkan sektor pertanian. Pada umumnya, petani di Desa Gondowangi mengalami masalah bedanya hasil pertanian dari berbagai lahan yang dimiliki. Pengabdian masyarakat ini dilaksanakan dengan metode pelatihan pengukuran kualitas tanah dan pembuatan infografik kualitas tanah. Kegiatan pengabdian dilaksanaan dengan cara pelatihan secara langsung di lahan milik para petani. Pelatihan pengukuran dilaksanakan secara langsung oleh petani pemilik lahan sehingga petani terbiasa menggunakan soil meter. Berdasarkan hasil pengabdian didapatkan berbagai lahan memiliki kualitas tanah yang berbeda dari segi pH dan kandungan unsur hara.

Abstract

Pelarutan selektif tembaga dari limbah printed circuit board (PCB) telah berhasil dilakukan. Logam tembaga yang terkandung di dalam papan PCB dapat dipisahkan menggunakan campuran hidrogen peroksida dan asam sulfat dengan variasi perbandingan volume 0 : 1, 1 : 1, 2 : 1, 3 : 1, 4 : 1, dan 5 : 1. Pemisahan optimal dilakukan dengan sistem perendaman selama 3 hari dengan campuran H2O2/H2SO4 = 3 : 1 (v/v). Jumlah tembaga yang terkandung di dalam papan PCB dianalisis menggunakan X-ray fluorescense. Tembaga yang terkandung di dalam PCB sebesar 57,7%. Pelarutan selektif dapat menurunkan kadar tembaga sehingga tembaga yang masih tersisa adalah sebesar 7,7 x 10-4 %. Penurunan kadar tembaga yang terkandung di dalam PCB mencapai 99,999%. Analisis spektrometri serapan atom dilakukan untuk mengetahui jumlah tembaga yang terlarut yaitu sebesar 25,415 mg/kg PCB.Leaching of Copper from Printed Circuit Board Waste with Hydrogen Peroxide. Leaching of copper from printed circuit board (PCB) waste has been successfully performed. The copper metal contained in the PCB can be separated using a mixture of hydrogen peroxide and sulfuric acid with a variation of volume ratio is 0 : 1, 1 : 1, 2 : 1, 3 : 1, 4 : 1, and 5 : 1. Optimal separation is carried out by the immersion system for 3 days using H2O2/H2SO4 = 3:1 (v/v). The amount of copper contained in the PCB was analyzed using X-ray fluorescence. The copper contained in the printed circuit board is 57.7%. The leaching process can decrease the copper content so that the remaining copper is 7.7 x 10-4%. The decrease of copper content contained in PCB reaches 99.999%. Analysis of atomic absorption spectrometry was conducted to determine the amount of dissolved copper that is 25.415 mg/kg PCB.
