Abstract

Salah satu limbah padat dari pabrik gula adalah bagas. Sisa penggilingan gula merupakan bagas yang cukup besar sehingga diperlukan proses lebih lanjut agar limbah tersebut tidak merusak lingkungan. Tujuan studi ini adalah membuat absorben dari limbah bagas dan mengamati perubahan sifat fisik dan kimianya. Pembuatan absorben dilakukan dengan menggunakan radiasi mesin berkas elektron. Proses iradiasi dilakukan dengan variasi dosis 15kGy, 30 kGy, 45 kGy dan 60 kGy. Sifat fisik absorben dapat diamati dengan menggunakan hasil persentase fraksi gel. Sifat kimia absorben diamati dari perbedaan spektrum infra merahnya pada saat sebelum dan sesudah ditambahkan monomer. Hasil yang diperoleh menunjukkan bahwa dosis radiasi yang semakin tinggi pada absorben akan meningkatkan sifat fisik (persentase fraksi gel). Analisis menggunakan spektra Fourier Transform Infra Red (FTIR) menunjukan perbedaan puncak-puncak serapan bagas sebelum dan sesudah ditambahkan monomer. Spektrum Differential Scanning Calorymetry (DSC) komposit hasil iradiasi menunjukkan bahwa iradiasi menyebabkan perubahan titik lebur.

Abstract

The addition of phosphate-solubilizing microorganisms (PSM) as biofertilizers can improve the quality of soil properties. A meta-analysis study was conducted to analyze the effect of PSM on soil properties. This meta-analysis has analyzed 20 research articles published between 1990 and 2023, which have reported the influence of PSM on soil properties. The value of effect size (ES) Hedges'd of available-P is 3.047 (p<0.001), ES of available K is 2.102 (p<0.001), ES of soil nitrogen (N) is 1.706 (p<0.001), ES of pH is  -2.738 (p<0.001), ES of soil organic carbon (SOC) is 1.087 (p=0.004), ES of N-NH4 is 0.636 (p= 0.013), ES of N-NO3 is 2.643 (p< 0.001), ES of phosphatase is 5.001 (p< 0.001), ES of alkaline phosphatase is 22.956 (p<0.001), and ES of acid phosphatase is 23.104 (p<0.001). The results showed that in terms of phosphate solubility, PSM is more effective on alkaline soils with high SOC content, very high P availability, and a sandy loam texture. PSM is more effective for K solubility on acidic soils, with very high SOC content, high P availability, and a loamy texture. PSM is effective in increasing soil N with acid soil characteristics, low SOC content, moderate available P content, and clay texture. According to this study, the Penicillium fungus ranks second in the fungal group in terms of phosphate solubilization capacity after the genus Azotobacter. The genus Peronospora showed the greatest potential in increasing soil N. In contrast, Burkholderia showed the greatest effectiveness in solubilizing K.

Abstract

One way to extend shelf life and maintain the quality of fresh chicken meat is to implement an active packaging system. This research aimed to develop active packaging in the form of pads used in chicken meat with dual functions: Super Water Absorbent (SWA) as an adsorbent system and Ethanol Emitter (EE) as an antibacterial release system. The packaging in this study was first carried out by making SWA/EE with a ratio of 0, 4, and 2 (b/v). Furthermore, SWA/EE granules were inserted into non-woven PP bags to form an adsorbent active packaging pad. The experimental design used was a Randomized Group Design (RGD) with 2 factors, namely SWA/EE pad ratio 0, 4, and 2 (b/v) with non-pad as control and storage time (0, 1, 3, 5, and 7 days). Each treatment was repeated 3 times. The results showed that the SWA/EE ratio 4 (w/v) had better ethanol release and water absorption rate compared to other treatments. SWA/EE treatment with SWA/EE ratio of 4 (b/v) showed a significant difference on the anti-bacterial activity of S. aureus (34.58 mm) and total bacterial growth on storage days 3, 5, and 7, with the lowest value on day 3 (1.52 log CFU/g). SWA/EE treatment did not significantly different on the antibacterial activity of E. coli and total bacterial growth at day 1 storage. Packaging with an SWA-EE ratio of 4 (w/v) has the potential to be a double active packaging that can be used on fresh chicken meat.
