Thanks to the phenolic compounds and acetic acid in the smoke powder, it has antimicrobial effects and can be used as an alternative to food preservatives. The purpose of this study was to investigate the potential of liquid smoke powder from durian rind as a chicken meatball preservative through organoleptic analysis (aroma, texture and colour). Spray drying was used to convert durian rind liquid smoke into smoke powder, and two types of bacteria, Escherichia coli and Salmonella typhimurium, were used to test the antibacterial properties of the smoke powder. Organoleptic test data were analysed using the SPSS version 16 and one-way ANOVA, followed by the least significant difference (LSD) test. The results of antibacterial tests on the E. coli and Salmonella bacteria indicated that the smoke powder had an inhibition zone of 10.55 ± 1 and 8.130 ± 12 mm, respectively. The organoleptic evaluation of aroma, texture and colour suggested that the meatballs could be preserved for 64 h. Meanwhile, the pH test results indicated that the meatballs could only be stored for 60 h.

However, this condition has not been able to make a real contribution to regional economic growth and to overcome poverty problems in Aceh. This study aims to examine the dimensions of sustainable patchouli farming and its implications for poverty alleviation. This study employed a descriptive explorative method by a case study approach, which focuses on patchouli farmers who engage in a small-scale plantation business in Aceh Jaya, Aceh Province by field observation, in-depth interviews focused group discussions. This study found that the economic condition of the community has stagnated to grow well, even though the performance of patchouli productivity is relatively good. Several crucial issues in patchouli farming practices show a pattern that illustrates the weak support for strengthening the community's economy....

In addition, the effect of PVP concentration (1-4%) was investigated to prepare membranes with better membrane antifouling performance and characteristics. Furthermore, functional groups, morphological structures, and membrane porosity were analysed by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and membrane porosity calculation. The surface SEM images revealed that the size of the modified membrane pores increased. The increase of the PVP concentration added, resulted in the number of modified membrane pores. FTIR spectra confirmed that PVP functional groups were dispersed in the PVDF membrane matrix. Optimum pure water permeability (PWP) of 60 L/(m2•h•bar) was achieved using 3% PVP, resulting in a humic acid rejection percentage of 80% and a water flux recovery ratio (FRR) of 85%. These findings indicate that the utilization of PVP as a pre-forming agent resulted in higher PWP, lower humic acid rejection, and good antifouling properties.

Fouling pada membran mengakibatkan penurunan kinerja membrane selama proses operasi. Oleh karena itu, modifikasi membran perlu dilakukan untuk meningkatkan sifat hidrofilik membrane. Pada penelitian ini modifikasi dilakukan dengan penambahan nanopartikel Mg(OH)2 yang bersifat tidak beracun, murah, dan mudah diperoleh. Penambahan aditif nanopartikel Mg(OH)2 pada membran PES dilakukan dengan cara pencampuran polimer dengan metode non solvent induced phase separation (NIPS) menggunakan pelarut dimethyl sulfoxide (DMSO). DMSO merupakan pelarut polar aprotik yang dapat melarutkan senyawa organik maupun anorganik dengan baik. DMSO juga merupakan pelarut yang tidak beracun, sehingga lebih aman dan ramah lingkungan. Penelitian ini bertujuan untuk menghasilkan membran PES hidrofilik dengan penambahan nanopartikel Mg(OH)2 dengan unjuk kerja terbaik. Pengaruh penambahan nanopartikel Mg(OH)...

There is no alternative to sustainable development, and the utilization of agricultural waste for wastewater treatment has been always a novel milestone in sustainable development goals. Agricultural-waste-based nano-activated carbon exhibits high porosity, great surface area, and unique surface functional groups that promote it to becoming a future and sustainable solution for wastewater treatment applications. Several modification approaches have been made to further enhance the adsorption capacity and reusability of such adsorbents. In this review, we presented the potential of agricultural-waste-based nano-activated carbon as a sustainable solution for wastewater treatment. We highlighted the fabrication process and properties of different nano-activated carbons in addition to different modification approaches to enhance its adsorption ca...

The development of the patchouli industry sector in Aceh faces serious challenges, especially the capacity building of farmers towards good agriculture practices, and innovation and technology. This study aims to identify the level of empowerment of farmers and the affecting factors. The study employed a questionnaire survey to 88 samples from 383 populations. Data analysis used a descriptive method and chi-square test. The results show that a low level of farmer empowerment is predominantly. The weakest elements are the ability to cooperate and solidarity; meanwhile, the ability to overcome obstacles is the highest, followed by the awareness and desire to change, and the ability to increase capacity to gain access. Farmer's perceptions on the group institutions, and program intervention have a significant association with empowerment, while the perception to characteristics of the social systems has no re...

The study's main objective was to produce a PUF-based adsorbent with high reactivity to remove Hg2+ in wastewater. This bentonite and magnetite filler-modified polyurethane foam (BMPUF) adsorbent was fixed in a bed column for the adsorption of mercury (II) ions from an aqueous solution. The effect of initial Hg2+ concentration on the removal rate and the effect of contact time on adsorption efficiency was investigated. Langmuir, Freundlich, and BET non-linear models were taken into account to determine the best adsorption isotherm fitting and obtain adsorption capacity, intensity, and pore volume. As a result, it followed the non-linear Freundlich model, and the average adsorption capacity and intensity were 0.466 mg/g and 0.923, respectively. The average BET-based pore volume obtai...

This research provided an effective and efficient method for purifying Aceh patchouli oil to secure high-quality patchouli oil. Purification was done by utilizing natural mineral sources that were sufficiently available in Aceh and applying them in various adsorption processes, analyzing the adsorption of Fe levels in patchouli oil, and characterizing nano adsorbents used in the adsorption process. Nanoparticles of zeolite and bentonite were used during the adsorption process with patchouli oil sourced from the South Aceh area. The adsorption process purified 20 mL of patchouli oil at a temperature of 45 ℃ with variable mass nano adsorbent 1; 3; 5 g, and variable stirring time 60; 180; 300 minutes. The purification filtrate was later analyzed for patchouli alcohol levels using Gas Chromatography-Mass Spectrometry (GC-MS) and Fe levels using UV-Vis Spectrophotometry. The characte...
