Abstract

Purposes. Sustainability Balanced Scorecard (SBSC) is the development of balanced scorecard as a comprehensive company performance appraisal method, which the assessment focus on financial perspective, customer, internal business processes, growth and learning as well as the social and environmental perspective as an effort of sustainability. This sustainability effort is in line with the legitimacy theory, which states that the company should be run in accordance with the prevailing norms of the place where the company is located. Madukismo Sugar Company (PG. Madukismo) is a company that has potential environmental destruction is the subject of this research. This research is intended to provide an overview of PG Madukismo's performance evaluation using the SBSC method, whether it is able to explain the legitimacy theory.Method. The case study with a descriptive qualitative method by triangulation system becomes a method of this research development.Findings. Outlined, the performance of PG Madukismo shows good results, the financial perspective shows some improvement, profit has increased, as well as efficiency. The customer's perspective also shows satisfactory performance, the high level of customer retention and the minimum level of complaints is enough to explain. The internal business process perspective results are also satisfactory, innovation on production, sales and after-sales processes are considered good. A less encouraging perspective is the perspective of growth and learning, even though employee retention is good but the amount of employee training actually shows a downward trend. Last but not least, is a social and environmental perspective. The results obtained were quite surprising, although in 2016 the news about Madukismo waste management was less pleasant, in 2018 Madukismo was able to improve its waste management and get a positive response from surrounding communities who said that the stench from Madukismo waste continued to decrease.Implication. This research gives insight and detail of how to assess a company using five perspectives of SBSC to prove that legitimacy theory can be applied and bringing the hope of sustainable business.Keyword: Sustainability Balanced Scorecard, green accounting, social and environmental, PG.Madukismo

Abstract

Excessive sun exposure to the skin can cause redness (erythema) and darkening of the skin (pigmentation). This effect can be prevented by using sunscreen. Kedondong leaves (Spondias dulcis Sol. Ex G. Forst) can act as a natural sunscreen because they contain secondary metabolite compounds with a conjugated double bond structure (chromophore), including phenolic and flavonoid compounds. The presence of conjugated double bonds in phenolic and flavonoid compounds is known to be able to absorb UV radiation thereby reducing its intensity on the skin. This study aims to determine the sunscreen activity of kedondong leaves based on the Sun Protection Factor (SPF), , the percentage of erythema transmission value (%Te), and the percentage of pigmentation transmission value (%Tp) and determine the secondary metabolite groups in kedondong leaf extracts and fractions. The research stages carried out were extraction of kedondong leaves by maceration, dechlorophyllation, followed by fractionation using n-hexane and dichloromethane, to obtain methanol extract, n-hexane fraction, dichloromethane fraction and methanol fraction. Then phytochemical tests were carried out on the extracts and fractions. Phytochemical tests showed that the secondary metabolite compounds in the methanol extract of kedondong leaves were alkaloids, phenolics, steroids and saponins. Furthermore, in the n-hexane fraction are steroids, the dichloromethane fraction is phenolic compounds, and the methanol fraction is alkaloid, phenolic and saponin compounds. Using a UV-Vis spectrophotometer at a wavelength of 200-400 nm, the sunscreen activity test showed that the dichloromethane fraction at a concentration of 120 mg/L was included in the extra protection category with an SPF value of 7,86±0,23; fast tanning with a %Te value of 15,99±0,83 and sunblock with a %Tp value of 32,72±1,09.

Abstract

Processing plastic waste, especially Low-Density Polyethylene (LDPE), is an environmental problem because it is difficult to decompose. One method of processing plastic waste is pyrolysis, which converts plastic into liquid fuels such as diesel. However, pyrolyzed diesel still contains impurities, such as sulfur, chlorine, and hydrocarbon compounds, which affect fuel quality, including acid number and viscosity. This study aims to determine the adsorbent characteristics of natural zeolite (ZA), chemically-physical activation zeolite (ZKF), and physico-chemical activation zeolite (ZFK), and to assess their effectiveness in improving the quality of diesel fuel from the pyrolysis of plastic waste. The test of zeolite as an adsorbent was conducted by measuring water and ash content and by characterizing it using Fourier Transform Infrared (FTIR), X-Ray Fluorescence (XRF), and a Gas Sorption Analyzer (GSA). FTIR results showed spectral changes indicative of the loss of OH groups and revealed the main functional groups of the activated zeolites. XRF results show that ZKF and ZFK have increased silica (SiO₂) content from 81.85% to 82.19% and 82.26%, and decreased iron oxide (Fe₂O₃) content from 0.94% to 0.63% and 0.62%. GSA analysis showed increases in the surface areas of ZKF and ZFK from 11.49 m²/g to 34.06 m²/g and 19.78 m²/g, respectively. Processing of pyrolyzed diesel using ZKF and ZFK showed a decrease in acid number from 1.03 mg NaOH/g to 0.25 mg NaOH/g and 0.20 mg NaOH/g, a reduction in viscosity from 5.45 cSt to 5.19 cSt and 5.13 cSt. The most effective adsorbent for reducing acid number and viscosity is ZFK, with a surface area of 19.78 m2/g, an average pore diameter of 5.99 nm, and optimal adsorption conditions at a stirring time of 4 minutes with an adsorbent mass of 1.5 grams in 50 mL of pyrolyzed diesel.

Abstract

The need for environmentally responsible extraction techniques has driven the development of green alternatives to conventional organic solvents. Deep eutectic solvents (DESs) offer a sustainable option due to their low toxicity, biodegradability, and simple preparation. In this study, a DES composed of glycine, glycerol, and water (1:11:15 molar ratio) was used as a green extraction medium to isolate bioactive compounds from the red algae (Eucheuma cottonii), providing an eco-friendly solution for efficient marine bioresource utilization. This final product offers a simplified process, as the resulting extract requires no further separation prior to application. The DES exhibited favourable physicochemical properties, including a pH of 5, density of 1300.14 kg/m³, viscosity of 0.0198 Pa·s, and a freezing point below 263.15 K. Phytochemical screening of the DES-based extract confirmed the presence of phenolic and terpenoid compounds. The extract was directly incorporated into sunscreen lotion formulations at concentrations ranging from 0 to 15% (w/w). All formulations showed good homogeneity, with the highest sun protection factor (SPF) value of 8.37 observed in the lotion containing 15% red algae extract. This research shows the success of extracting natural anti-UV ingredients in an environmentally friendly and efficient manner.

Abstract

Mackerel fish bones are commonly discarded as waste and may contribute to environmental pollution. This study aimed to extract gelatin from mackerel fish bones and evaluate its use as a coagulant aid with alum for the removal of organic matter and total suspended solids (TSS) from peat water. Gelatin was extracted and its functional groups were characterized using Fourier transform infrared (FTIR) spectroscopy. Treatment performance was evaluated through jar test experiments by varying Gelatin dosage (2, 4, 6, 8, and 10 g/L) and pH (4–8). Organic matter concentration was determined using the permanganometric titration method, while TSS was measured using the nephelometric method. The gelatin yield was 2.45%, and FTIR analysis confirmed the presence of amide functional groups, indicated by N–H stretching at 3353 cm⁻¹. The addition of gelatin enhanced alum performance, with optimal conditions at a dosage of 8 g/L and pH 7, achieving removal efficiencies of 89.3% for organic matter and 87.8% for TSS with a sedimentation time of 15 minutes. These findings demonstrate the potential of fish bone–derived gelatin as an effective and sustainable coagulant aid for peat water treatment.
