“…The increase in pore diameter and pore volume as well as a decrease in the surface area caused by surfactants that fill most of the space on the clay surface results in an increase in pore volume and pore diameter. The result obtained in this study is twice the surface area of 4.3 m2/g reported by Lee et al, Rihayat et al (2019), Safitri et al (2020), Mudzielwana et al (2019). The morphology observed by SEM for the kaolin-modified surfactant (SMK) produced by Ultrasonic-assisted is shown in Figure 3.…”

This study aims to test the reservoir wastewater containing domestic waste using a modified kaolinite adsorbent with Alkyl Benzene Sulfonate surfactant using ultrasonic technology (KM). First, the adsorbent to be used is characterized using several different techniques such as SEM analysis, and FTIR and the calculation of the efficiency of the adsorbent concerning contact time with wastewater. Meanwhile, the wastewater tested was tested for the effect of contact time on TDS and PH. The results of the analysis show that the maximum waste reduction efficiency occurs in modified kaolin (KM), where adsorption occurs faster than in unmodified natural kaolin (PK). The maximum percentage is 84, 21% for metal removal efficiency using modified kaolin at a contact time of 45 minutes and a weight of 1.8 g of adsorbent, while kaolin without modification has an efficiency of 62.47% at a contact time of 80 minutes and a weight of 1.8 g of adsorbent. The contact time test on the TDS value of wastewater that has been adsorbed with KM shows that the TDS value is getting lower over time, which indicates the Hg (II) ion has been dispersed and fused so that the Hg (II) metal in the water is reduced. The use of the adsorption method with the help of ultrasonic technology is proven to be more efficient in accelerating the removal of Hg (II) ions by increasing the surface dispersion of the adsorbent with metal ions in water. The contact time test on the TDS value of wastewater that has been adsorbed with KM shows that the TDS value is getting lower over time, which indicates the Hg (II) ion has been dispersed and fused so that the Hg (II) metal in the water is reduced.

“…Perlakuan pengeringan daun jeruk selama 4 jam mengakibatkan penurunan rendemen minyak atsiri hingga 50% (Setiyoningrum et al 2018). Hasil penelitian ini selaras dengan penelitian Safitri et al (2020) yang mengemukakan bahwa perlakuan pengeringan daun sereh wangi selama 1 hari memberikan rendemen tertinggi yaitu 0,84% dibandingkan rendemen yang diperoleh dari pengeringan 2 dan 3 hari.…”

Citronella oil is one of the non-timber forest products (NTFP) and commercially obtained from the distillation of the leaves of the Cymbopogon nardus L. This study aims to determine the effect of the size of the distillation raw material and storage time of the raw material on yield and determine the antimicrobial properties of citronella oil from plants in the production forest Register 40 KPH Gedong Wani, Lampung Selatan Regency. The research was conducted using a complete randomized block design (RAKL) with two factors, namely the size of the distillation raw material (whole leaf, 5 cm, 10 cm, and 15 cm) and the storage time of the raw material (fresh, 2 days, and 4 days) which was carried out in 3 replications. The variables measured were yield, specific gravity, and solubility of citronella oil in alcohol. The inhibition ability test of citronella oil against bacteria using essential oil obtained from distillation at the highest yield conditions, namely fresh leaves and leaf size of 5 cm using the diffusion well method. The results showed that the storage time factor, the size of the distillation raw material, and the interaction between the storage time and the size of the raw material had a significant effect on the yield of citronella oil. The highest yield of citronella oil was achieved in the condition of fresh leaves with a size of 5 cm, namely 2,09%. Density and solubility in alcohol of citronella oil produced met SNI 06-3953-1995 standard, respectively 0,8718-0,8928 g/ ml and 1:2. Citronella oil has strong antibacterial properties against Propioni acne, Escherichia coli, Staphylococcus aureus, and Bacillus cereus with inhibition zone diameters were 40,20 mm, 18,36 mm, 13,07 mm, and 18,80 mm, respectively. Citronella oil from plants in Register 40 KPH Gedong Wani has potential as a raw material for the cosmetic and disinfectant industry. Keywords: antimicrobial, citronella oil, yield

Biodegradable polymers are seen as a potential solution for the environment generated by plastic waste. The purpose of this study was to see the effect of adding a catalyst to the manufacture of PLA/PCL-Catechin-Chitosan as a raw material for making plastics . This research was carried out with variations in the addition of ZnO catalyst 0.1 % (PPXya), 0.2% (PPXyb) and 0.3% (PPXyc ). From the results of the analysis using Fourier Transform Infrared (FTIR) obtained stretching groups of OH, CO and C= O at wavelengths (3860, 1060 and 1753) cm-1 at the addition of 0.3% ZnO catalyst (PPXyc ). Based on the analysis of the thermal stability using Thermogravimetry (TGA) the decomposition temperature was obtained at 387℃ with the addition of catalyst 0.3% (PPXyc ). Morphological analysis using Scanning Electron Microscopy (SEM) showed that the surface structure of PLA was in the form of widespread lumps. The more concentration of additional catalyst used can affect the formation of PLA/PCL-Catechin-Chitosan. The result of the tensile test tensile analysus are greater the addition of ZnO catalyst in the sample PLA-PCL-Catechin-hitosan can to be able to increase the tensile value of the of the sample.
