Abstract
Seaweed farming is an important livelihood in coastal areas in Indonesia. This activity is the only cash source for farmer’s daily needs. Nevertheless, they still suffer due to their lifestyle such as debt trap. This study aimed to describe the debt trap in seaweed farmers living in Bungin Permai village, Tinanggea district, South Konawe, SE Sulawesi, Indonesia. This study was done using a survey method. Structured questionnaire and in-depth interviews were done with a series of livelihood household surveys for randomly selected 98 respondents working as seaweed farmers. From this study, it was found that debt is their lifestyle. It was caused by their simple lifestyle. They always consider that the high fisheries resources from farming and fishing activities can maintain their daily life. Their expenditures are more than they can afford, especially on non-food and social expenditures (extravagant lifestyle). In addition, they mostly do not prefer to save their money in bank. Therefore, the only way to meet their daily needs is by borrowing from their middlemen.

Abstract
Formaldehyde is a harmful compound that is usually used as an illegal preservative agent in fisheries products to prevent spoilage and extend shelf life. In several fishery products, formaldehyde can be formed endogenously during the post mortem process through degradation of trimethylamine oxide (TMAO) by enzymatic process. Exogenous and endogenous formaldehyde can affect the textural and structural change in fish muscle tissue significantly influencing flesh quality. This study was aimed to characterize the structural change of the muscle tissue in Bombay duck (Harpodon nehereus) that is immersed with formaldehyde solution on chilling storage temperature. The Scanning Electron Microscope (SEM) analysis was used to identify and characterize the structural change in muscle tissue samples, which were immersed with formaldehyde solution 0%, 1%, 3%, and 5%. SEM analysis identified that in transversal section samples immersed with formaldehyde solution 0% (control) intermyofibrillar space was increased significantly during post mortem storage. This was in line with the increased of myofibril, connective tissue and sarcolemma lost on samples. Furthermore, on samples that were immersed with formaldehyde solution 1%,3%, and 5% the degradation of myofibril and intermyofibrillar was can be held and the connectivity tissue muscle still showed strong aggregation during post mortem storage.

Abstract
On the drilling operation, drilling mud is essential in safely and optimizes drilling operations to prevent drilling problems. Drilling problem are caused by many factors. One of the factors causing drilling problems comes from the condition of formation. The condition of formation that makes the drilling problem comes from the shale formation. The shale formation tends to become sloughing and swelling. Then to prevent that, the mud drilling must be designed to encounter that condition to reduce the risk of the drilling operation. The cutting sample for this study was from an EG wellsite with reactive clay that caused the shale problem. To determine the effectiveness of the material used in drilling mud, this study used the methylene blue test and the geonor development test. In this study, crude coconut oil (CCO) as natural material showed a good condition for use in mud drilling.

Published: June 2022

Abstract
Garlic essential oil is one of the natural antimicrobial agents which has a broad spectrum of inhibition against microbes. However, if directly applied to the packaging material, it will affect the tensile strength of the packaging. In order to overcome the weakness, this study has produced an antimicrobial active packaging with the concept of a headspace food system, the principle of this packaging is the adsorption of active compounds on a carrier material that can release them slowly. Garlic essential oil was adsorbed on zeolite nanofiber cellulose tablet composites. The effect of adding cellulose nanofibers to tablets has been investigated. The effectiveness of tablet composites was assessed by conducting a release test which was carried out by calculating the weight reduction of tablet composites every day for six days. Based on the release test, the addition of 3% nanofiber cellulose to the composite has a reliable ability to slow the release of garlic essential oil. Antimicrobial inhibition of e coli and s typhi bacteria was also tested using the agar diffusion method. Tablet composites with the addition of 3% nanofiber cellulose have a very strong inhibitory power against e coli bacteria and have moderate inhibition against s typhi bacteria

Abstract
Sugar sap from Nipa (Nypa fruiticans) palm is one of the promising sustainable feedstocks for ethanol production. There are different stages and processes needed for the sap to produce ethanol particularly: collection, fermentation, and distillation. In order to produce high ethanol concentration and yield, each stage or process needs to be optimized and improved as such, this study optimized the flow rate and temperature of the cooling system of a 10 L full electric Reflux distiller for the production of a fuel grade (95%) bioethanol from nipa sap. The optimal power density for the 10 L full electric reflux distiller was also determined. Optimizing these parameters improved the concentration of the ethanol, ethanol yield and also decreased the operational cost of the 10 L full electric reflux distiller. First step was to determine the power density required for the 10 L Lab-Scale Distiller through experiment using different power density. After identifying the power density, multiple trials were performed with 2 protocols being the continuous method and recirculating method of the cooling system. Results showed that a flow rate of 0.77 L/min, a 27 °C cooling liquid temperature and a 100W/m3 power density were obtained. An increase of 154.2% in volume of consistent 95% concentration yield was observed. Also, there was a significant increase in the yield. Continuous method was faster by an average of 26 minutes compared to the recirculating method.

Abstract
Indonesia is one of the most biodiesel producers globally, with a total production capacity of around 12 million kL in 2020. Recently, Indonesia has been implementing a mandatory biodiesel program with at least 30% (B30). However, the utilization of B30 still has challenges faced regarding carbon deposition and water content. Therefore, this study aims to determine the effect of bio-additive from essential oil to reduce the particulate as well as the water content of B30. A single essential oil of clove terpene, rhodinol, and turpentine oil, as well as their mixtures, were used in this study. A concentration of 0.5% was used for a single essential oil of clove terpene, rhodinol, and turpentine oil. Meanwhile, the concentrations of clove terpene, rhodinol, and turpentine oil mixtures were 1: 1: 8 (BA1); 0.33: 0.67: 8 (BA2); 0.5: 1.5: 8 (BA3). For the case of single essential oil, the largest reduction in the particulate matter as much as 38.26, 62.85, and 91.11% was found by adding 0.5% clove terpene at 4, 6, and 14-μm filtration, respectively. Furthermore, the best reduction in water content was observed with the addition of turpentine, reducing the water content of B30 from 312 to 282 ppm.

Authors: Salam Wildan Q , Julian Helen , Kresnowati M T A P 
Published: June 2022

Abstract
Sugar alcohols, such as sorbitol, xylitol, and arabitol, are natural sweeteners with comparable sweetness to sucrose but have lower calories. Besides, they have unique characteristics such as teeth-friendly and low glycemic index, which are attractive for food industries. The vast availability of lignocelluloses biomass waste offers the potential of sugar alcohol production from lignocelluloses, for example, via hydrolysis and fermentation. Besides containing sugar alcohol, fermentation broth also contains other substances: biomass cells, metabolic products, leftover substrates, and inorganic minerals. Downstream processing is necessary to process further the produced sugar alcohol in fermentation broth to the commercial crystal of sugar alcohol. This paper reviews the crystallization of sugar alcohol and the preceding processes necessary to obtain high-quality sugar alcohol crystals. In particular, membrane-based processes to pretreat the fermentation broth before the crystallization process is proposed.

Authors: Wu Weiran , Shao Mengying 
Published: June 2022

Abstract
Ultraviolet light emitting diode (UV-LED) is a hygienic treatment in effectively inactivating pathogenic microorganisms on surfaces and objects. However, how the combination types of different light influence the disinfection efficiency remains elusive. In this study, the effects of single and double wavelength on surface disinfection were assessed. Meanwhile, the effects of different radiation modes on surface disinfection were studied. The results showed that the dual-wavelength (UVA and UVC) had better disinfecting effect than the single wavelength. For the irradiation mode, UVA pre-treatment enhanced the inactivation effectiveness of microorganisms on surface. In detail, 367 nm UVA pre-treatment followed by 265 nm UVC worked better as the log inactivation of the dual-wavelength was more than 2 times higher than that from the sum of applying single exposure separately. Moreover, the radiational order had a significant impact on disinfection effect. In addition, extending the irradiation time could enhance the inactivation efficiency. In summary, this study provides a new insight into the development of surface disinfection technologies.

Published: June 2022

Abstract
As natural carbon sinks, coastal wetlands are of great significance to alleviate global climate change. However, due to environmental pollution, the soil carbon sequestration capacity of coastal wetlands is decreasing, and then the emission of CO2 is accelerated. The Yellow River Delta is one of the largest deltas in China. Economic development and human activities have led to the input of large quantities of microplastics. Microplastics can alter soil properties, causing the emission of CO2 to be affected. However, the impact of common microplastics in coastal wetlands on CO2 generation and emission is not clear. In this study, tread particles (TP) and polypropylene (PP) particles were applied to coastal wetland soil to study their effects on greenhouse gas CO2 emissions. The results showed that the cumulative emission of CO2 increased by 32.7% - 49.5% and 13.9% - 24.6% respectively compared with CK 14 days after the addition of TP and PP. The promoting effect of TP was stronger than that of PP. The results provided theoretical and basic data support for the evaluation of greenhouse gas emissions and atmospheric environmental effects of Yellow River Delta wetlands under microplastics pollution.

Published: June 2022

Abstract
Petroleum is an important industrial raw material that enters the soil in large quantities due to its production and extraction, causing toxic effects on soil organisms. To evaluate the toxicity of petroleum-contaminated soil, the study was conducted to qualitatively and quantitatively investigate the ecotoxicity of petroleum-contaminated loessal soil with different levels of petroleum. Using earthworms and wheat as indicator organisms by microcosm toxicity test. The earthworm test showed that the body weight of earthworms decreased by more than 20% with the addition of 800-3,000 mg/kg TPHs and by more than 50% with the addition of 13000 mg/kg or more TPHs. The EC50 values at 7 and 14 d were 21,130 and 25,314.5 mg/kg, respectively. The number of sprouts, shoot length and root length of wheat were inhibited in the soil with petroleum, and the more severe the petroleum contamination, the stronger the inhibition. The seedling elongation index was better than the root elongation index. The experimental results showed that earthworms had the lowest EC50 values for body weight inhibition at 7 days and the lowest IC50 values for mean shoot length at 7 days in wheat, which can be used for toxicity prediction and early diagnosis of petroleum-contaminated soil.

Abstract
As a promising technology, the photocatalysis/persulfate-oxidation hybrid (PPOH) system has been used to degrade organic pollutants. Under visible light, a new N-Doped BiOCl/PS system was developed to degrade Rhodamine B (RhB) effectively. Using an ethylenediamine-assisted hydrothermal technique, N-BiOCl photocatalyst was manufactured and analyzed. Nanoplates self-assemble N-BiOCl to form an aggregated flower-like microstructure, which according SEM measurements. The absorption edge of N-BiOCl sample has a significant red shift toward longer wavelengths. In addition, the SBET values of the N-BiOCl is significantly increased. Compared with BiOCl, using 0.3 g/L N-BiOCl photocatalyst and 2 mM PS, 10 mg/L RhB (100 mL) could be removed in 8 minutes with the removal rate of 98% under visible-light irradiation. Through chemical quenching experiment and EPR direct detection, it is proved that the main reactive oxygen species (ROS) of visible-light catalytic system are ·OH, ·SO4
-, ·O2
- and h+, in which ·O2
- and h+ play a leading role.
