Abstract

ABSTRAKKegiatan pendayagunaan dan mentoring pengolahan limbah organik rumah tangga pada jurnal ini merupakan bentuk tindak lanjut dari kegiatan penyuluhan yang telah dilakukan sebelumnya (Perwitasari dkk., 2021). Dengan menggunakan metode ringkas yang irit lahan, masyarakat Kelurahan Gebang Putih telah mampu mengolah limbah organik sederhana menjadi kompos siap guna dengan menggunakan EM4 sebagai bioaktivator. Metode yang dikembangkan pada kegiatan pengabdian ini adalah melalui metode mentoring secara online dengan kader PKK yang ada di Kelurahan Gebang Putih, Surabaya.  Meski mentoring tidak bisa dilakukan secara langsung, kader PKK bersama perwakilan warga telah berhasil mendayagunakan sampah organik rumah tangga sebagai kompos organik. Kegiatan ini terbukti mampu meningkatkan nilai guna limbah organik menjadi semakin bernilai ekonomis. Warga menjadi lebih hemat karena tak perlu lagi membeli kompos jika ingin bercocok tanam. Harapannya, kelak kompos akan menjadi salah satu peluang ekonomi yang menjanjikan bagi warga Kelurahan Gebang Putih. Kata Kunci: pendayagunaan; mentoring; EM4.ABSTRACTThe utilization and mentoring activities for simple organic waste processing in this journal are a form of follow-up to the counseling activities that have been carried out previously (Perwitasari et al., 2021). By using a compact method that saves land, the people of Gebang Putih Village have been able to process simple organic waste into ready-to-use compost using EM4 as a bioactivator. The method developed in this service activity is through an online mentoring method with PKK cadres in Gebang Putih Village, Surabaya. Although mentoring cannot be done directly, PKK cadres together with community representatives have succeeded in utilizing household organic waste as organic compost. This activity is proven to be able to increase the use value of organic waste to become more economically valuable. Residents become more efficient because they no longer need to buy compost if they want to grow crops. It is hoped that in the future compost will become a promising economic opportunity for residents of Gebang Putih. Keywords: development; mentoring; EM4.

Abstract

The requirement to discover low-cost and high-efficiency adsorbents material for the heavy metal removal of industrial effluents has been growing attention for many environmental researchers. Natural materials are being studied intensively as adsorbent materials because of their abundant source, low-cost processing, and relatively high adsorption efficiency. This study investigates the tofu dregs as adsorbents material to remove chrome metal, the main element in tannery liquid waste. Analysis of experimental data from adsorption processes is crucial to understand and predict removal mechanisms, efficiency, or required adsorbent mass under given initial conditions. Langmuir and Freundlich's adsorption isotherms were applied to the experimental data to determine their intrinsic parameters. The intrinsic parameters of Langmuir and Freundlich adsorption isotherms can subsequently be used to analyze the adsorption mechanism. This was achieved by combining the isotherms equation with mass conservation of solute before and after adsorption

Abstract

Ultrasound-assisted Extraction (UAE) is one of the potential ways to increase the yield and quality of bioactive compounds. Besides, the UAE is environmentally friendly since the solvent used is a lesser, non-toxic solvent, time-saving, and operated at a lower temperature, leading to the increase of mass transfer. Ultrasound is one of the wave sounds that have a frequency range that is above the range that can be heard by humans (20 MHz). This wave could cause the breakdown in plant tissue via cavitation, the forming of vacuum bubbles from a wave sound on a liquid material. The breakdown of plant tissue leads to the release of bioactive compounds. These compounds, then, are dissolved in the solvent. The types of bioactive compounds that can be extracted using ultrasound waves are polyphenols, carotenoids, aromatic compounds, and polysaccharides from plant matrix. The UAE method is affected by the temperature, frequency, and amplitude of the wave, density, types of solvent, extraction time, and plant matrix. This article would review the principles of UAE method, cavitation, the characteristic of tissue exposed to ultrasound, and the devices used during the extraction.

Abstract

The pulsed electric field (PEF)has been extensively studied in milk processing. However, treatment conditions still need to be improved to meet safety for consumption. This study aimed to determine optimum conditions by varying PEF and preheating treatment time. Free fatty acids (FFA), pH, and vitamin C are used to assess the milk quality. Preheating temperature is fixed at 70°C and the treatment time: 10, 20, and 30 minutes. PEF parameters are  electric field, 66 μs pulse width, and the applied time of 2, 4, and 6 minutes. The pH value and preheating treatment time show a negative linear relationship in the range of 6.75-7.15, while PEF treatment time did not significantly affect pH. The FFA linearly increases as preheating treatment time increases from 0.0053-0.0097%. Vitamin C decreases as preheating treatment time increase from 0.003-0.0049 mg/ml. PEF treatment significantly affects vitamin C, where vitamin C decreases as treatment time increases. Preheating and PEF treatment time show positive effects on the organoleptic properties of milk. The organoleptic properties values are flavor 3.93, aroma 4.00, and color 3.9 out of 5.

Abstract

Electron-hole pair (exciton) generation and extraction from solar-cell photoactive layer is the main parameters determined solar-cell performance. Generally solar-cell consists of a photoactive layer sandwiched between electron transport layer (ETL) and hole transport layer (HTL). Exciton separation and extraction from photoactive layer depend on several properties: energy level match of photoactive layer and charge transport layer, surface contact area of photoactive layer and charge transport layer, and charge transport properties of charge transport layer. ETL and HTL should meet several characteristic e.g.: high transparency in UV-visible light region, high degree of crystallization to minimize charge lose and high electron or hole mobility. In this study we try to fabricate ZnO as an ETL of hybrid solar-cell with sol-gel method combined with reflux treatment. The quality of ZnO ETL highly effected by precursor solution properties; solution homogeneity, viscosity and stability. These precursor solution properties depend on chemical composition and reaction condition, reflux treatment designed to enhance precursor solution reaction time and increase solution stability. Previous study shown low solution stability of ZnO precursor prepared with sol-gel without reflux treatment which resulting on low ETL quality. Visible observation of the resulting precursor solution showed that reflux treatment enhances solution stability, while solution prepared without reflux treatment easily formed precipitation phase. Furthermore, ZnO powder prepared with reflux treatment exhibit preferable crystallization and small ZnO crystallite size. Low-temperature crystallization of ZnO prepared with sol-gel method combined with reflux treatment, make it is possible to fabricate thin film with small particle size therefore able to enhance surface contact area of photoactive layer and ETL.

Abstract

This review article focused on the investigation of UV radiation's interactions with PET plastic in photografting. The photografting technique involved exposing PET packaging to UV radiation before utilizing it to package food. Surface graft polymerization was frequently carried out using UV light, frequently in the presence of a photoinitiator or photosensitizer. The results were intriguing since UV irradiation caused by PET and UV interaction will result in a hydrophilic nature in order for surface photography to create photografting and PET film with antibacterial properties. Therefore, many other industries, including the food industry, use photografting in this way.
