Abstract

Recycled waste management, especially in the Giri Mulyo area, is still less than optimal. Giri Mulyo itself is a community village located in Karang Joang village, North Balikpapan sub-district. Most of the residents of Giri Mulyo work as farmers. Based on information from the surrounding community, there has been a decrease in agricultural yields since the covid-19 pandemic. The decrease in income and the increase in the price of fertilizers sold in the market have forced farmers to reduce the amount of fertilizer applied to their agriculture. Based on these problems, an alternative fertilizer that is more friendly to the pockets of farmers in the Giri Mulyo area is needed. So far, many local people have used food waste to make compost as an alternative to fertilizer. However, this method is considered to take a long time and cause unpleasant odors in their environment and also the durability of compost is still quite low. To overcome these problems, the local community needs to be given socialization about information on making organic fertilizer made from household waste, does not require a long time in the manufacturing process and has a high level of product durability. The basic material used is eggshell waste. Organic fertilizer made from eggshell waste contains a high amount of calcium so that it has a good impact on the maintenance of nutrients in the soil, in line with the increase in plant fertility. In addition to being used as a medium for making liquid organic fertilizer, we also provide training in making mosaic pre-works made from eggshell waste to increase the creativity of local residents. The community service activities began with a location survey and interviews with the partners, Giri Mulyo RT 22 residents and teachers of SDN 012 North Balikpapan, which is located in the same location. Next, socialization on recycling eggshell waste into more valuable products was conducted. The activity ended with the residents involved filling out a questionnaire regarding the community satisfaction survey of the activities carried out. The purpose of this activity is to provide knowledge and insight to the community about making liquid organic fertilizer and mosaic artworks from eggshell waste.

Abstract

Biomass-based products are increasingly being used in industrial applications, but these innovations require efficient pretreatment to standardise the raw materials. In this study, the characteristics of oil palm mesocarp fibres after alkali processing were evaluated. The process consisted of two stages: delignification and bleaching. The organosolv extraction method was used to increase the efficiency of delignification during the bleaching stage. The mesocarp fibres were analysed using the kappa number test, scanning electron microscopy and Fourier transform infrared spectroscopy. A decrease in kappa number was observed, indicating a lower lignin content in the mesocarp samples. The FTIR spectrum showed a decrease in the peak intensity of C=C bonds in lignin at wavelengths of 1400-1500 cm-¹. Structural changes in fibre morphology after delignification and bleaching were observed, indicating that lignin had been successfully extracted from the mesocarp fibres. Optimal conditions for kappa number reduction were obtained at a NaOH concentration of 1 M, a delignification time of 4 h and a NaOCl volume of 280 ml (28 ml/g).

Abstract

Rubber seeds are one of the plantation commodities that are underutilized by the Indonesian people, apart from being the generative seeds of rubber trees. Rubber seeds have a reasonably high vegetable oil content of 68.53% with a carbohydrate content of 6.99%, protein content of 17.41%, and ash content of 3.08%. This study aimed to obtain food oil from rubber seeds with fewer chemicals and more affordable production costs. This study investigates the properties of food oil from rubber seeds and analyzes the cyanide content. The oil extracted using the traditional method yielded an 8.48% oil content. The rubber seeds were soaked for four days with rice husk charcoal (1:1) to reduce cyanide levels, followed by cooking to obtain the oil and bleaching with bentonite for purification. The oil was characterized according to Indonesian National Standards (SNI), assessing cyanide content, organoleptic properties, water content, acid values, and peroxide numbers. The resulting oil had a density of 0.87 g/cm and a cyanide content of 0.54 ppm. The tests showed a water content of 0.04%, an acid value of 0.4 mg NaOH/g, and organoleptic properties that met SNI standards. However, the peroxide value of 13.5 meq O2/kg was slightly above the standard, making the oil non-edible.

Abstract

The butterfly pea flower can be used as a food coloring to provide color, enhance visual appeal, and maintain or improve its organoleptic properties. Its role is not only limited to aesthetic aspects, but also has a significant health impact. Antioxidants owned by telang flowers have health potential, namely as anti-microbial, anti-depressant, anthelmintic, anti-cancer, and anti-diabetes. Therefore, the purpose of this research is to produce a powdered food coloring using telang flowers as the base material, which contains anthocyanins as a high source of antioxidants. This research method includes extraction with a 1% acetic acid solvent, a solubility test, a yield test, water content, and anthocyanin content. Maltodextrin (5,10,15%) and Carboxy Methyl Cellulose (CMC) were used as good capsulants. The total anthocyanin content determination test used the UV-Vis spectrometry method. The test results showed that increasing maltodextrin concentration was directly proportional to solubility, yield, and moisture content but inversely proportional to total anthocyanin content.

Abstract

Palm oil mill effluent (POME) is high strength wastewater obtained from palm fruit processing, which contains high chemical oxygen demand (COD), biological oxygen demand (BOD), and other contaminants. The pollutant load in POME can serve as a source of nutrients for microalgae growth. As a result, the goal of this work was to utilize Spirulina sp. and Nannochloropsis oculata to reduce the nutritional content of POME while producing biomass rich in high-value chemicals. The cultivation was conducted in a batch reactor using various POME fractions (0-20%) under 5,000 lux light intensity and continuous aeration at a temperature of 22-28C and a salinity of 30 ppt for 14 consecutive-days. The results demonstrate that Spirulina sp. produced the most biomass at 15% POME, accounting for 4.670.95 g/L with 0.570.11 1/day of growth rate and 3.33% of COD reduction efficiency. Meanwhile, Nannochloropsis oculata thrived in 20% POME, producing 4.430.36 g/L biomass, 1.180.31 1/day growth rate, and 14.43% COD reduction efficiency. In the proximate analysis. Spirulina sp. and Nannochlorpsis oculata provided 0.87%; 1.11% lipid and 1.03%; 0.86% protein, respectively.

Abstract

This study explores the potential of tofu waste as a cost-effective alternative growth medium for cultivating Spirulina sp. and Nannochloropsis oculata, addressing the high costs of traditional nutrient media that limit large-scale applications. Despite the nutrient richness of tofu waste, its use as a sustainable growth substrate remains underexplored. This research aims to fill this gap by evaluating the growth performance and nutritional suitability of these microalgae in tofu-based media compared to standard controls. The cultivation process was conducted in a closed photobioreactor system, with harvesting methods including flocculation, centrifugation, and filtration. Results showed that tofu waste media supported biomass production comparable to standard cultivation media, with the highest biomass concentrations recorded at the 20% tofu waste treatment, yielding 0.23 ± 0.05 g L-1 for Spirulina sp. and 0.53 ± 0.2 g L-1 for Nannochloropsis oculata. At this concentration, the final COD levels were 840.84 mg L-1and 825.90 mg L-1, respectively. The lipid and protein contents were 2.44% and 1.71% for Spirulina sp., and 1.21% and 1.50% for Nannochloropsis oculata, respectively. These findings demonstrate that tofu waste can serve as an effective and low-cost growth substrate for Spirulina sp. and Nannochloropsis oculata, promoting circular economy principles within many sectors such as energy, food, and agriculture. This study underscores the potential of waste utilization to enhance the sustainability and economic viability of microalgae cultivation.
