Various industrial sectors, from food and drug production to textiles, have widely used pigments or dyes as coloring agents. Generally, we can distinguish between two types of coloring agents: synthetic and natural. Currently, the use of synthetic colorings is a topic of debate due to their potential health risks, toxicity, and environmental pollution. This prompts a deeper exploration of natural resources as a more secure substitute for coloring agents. Plants, animals, microbes, and fungi can all provide natural coloring agents. Besides animals and microbes, some challenges in developing plants as major sources of natural coloring agents include variations in production or harvest times, strongly influenced by season, weather, and the intensity of sunlight. These factors influence not only the stability of the produced color but also its physicochemical properties, such as solubility and pH. Moreover, overexploitation of plants has an impact on ecosystem imbalances and leads to extinction. Among natural resources, pigments or dyes from fungi have shown their potential to address these challenges. This review focuses on the potential of various microfungi that produce natural dyes, especially from Monascaceae, Trichocomaceae, and Nectriaceae, as well as the classification based on their chemical structure. Furthermore, we describe their diverse biological impacts as antioxidants, antibiotics, antidiabetics, anticancer agents, and anti-cholesterol agents, along with their health advantages.

Jetis Batik Industry in Sidoarjo is recognized as a prominent batik center in East Java. Batik is known as an industry that uses both natural and synthetic dyes. This can serve as a source of environmental pollution. This study is to evaluate the quality of wastewater generated by Jetis Batik in Sidoarjo. The determined quality is then evaluated according to Permenkes 02 of 2023 and PerGub Jatim Number 72 of 2013. In this research, batik wastewater samples from 20 batik cottage industries in the Jetis region of Sidoarjo were used. It is acknowledged that it does not meet the clean water quality standards set by the Minister of Health Regulation Number 02 of 2023 in terms of TDS parameters, turbidity, color, Fe, Mn, nitrate, nitrite, pH, and chromium. Subsequent research in accordance with East Java Governor Law No. 72 of 2013 showed that TDS, pH, Fe, Mn, Cr, COD and BOD exceeded the quality criteria established by law. In addition, according to the East Java Governor Regulation No. 72 of 2023, batik liquid waste is classified into categories I, II, III, IV, and seawater, which is considered unsuitable for discharge into the marine environment. Immediate disposal of batik liquid waste into water sources without prior treatment poses a significant risk of environmental contamination.

Nickel (II) hydroxide (Ni(OH)₂) nanoparticles have attracted significant research interest due to their potential in applications such as supercapacitors, batteries, and electrocatalysis. However, conventional synthesis methods often face challenges related to high costs and complex instrumentation. This study presents a simple, low-cost, and controllable approach for synthesizing Ni(OH)₂ nanoparticles using a surfactant-assisted electrochemical method. The synthesis was conducted through electrolysis at 100°C in an aqueous solution containing sodium citrate, with Tween 20 employed as a structure-directing agent, Tween 20 was effective in producing smaller, dispersed, quasi-spherical particles while preventing severe agglomeration. The resulting nanoparticles were characterized using various analytical techniques, including UV-Vis and FTIR spectroscopy, X-ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), and electron microscopy (TEM/SEM). UV-Vis analysis showed a characteristic absorption peak at 387 nm, confirming nanoparticle formation. XRD analysis validated the synthesis of a nanocrystalline hexagonal Ni(OH)₂ phase. Electron microscopy revealed a hierarchical, flower-like morphology composed of nanosheets and demonstrated that Tween 20 was effective in producing smaller, dispersed, quasi-spherical particles while preventing severe agglomeration. Furthermore, the thermal decomposition of Ni(OH)₂ into highly crystalline cubic, NiO via calcination was confirmed by TGA, XRD, and FTIR analyses, with the main decomposition occurring at approximately 335°C. This research demonstrates an effective and economical route for producing Ni(OH)₂ nanoparticles with controlled morphology, enhancing their potential for practical applications.

The increasing volume of waste in Indonesia poses environmental challenges, especially incinerator ash residues that contain heavy metals and have the potential to contaminate soil. This study aimed to evaluate the utilization of incinerator ash combined with deer dung as an alternative growing medium for ornamental betel nut (Epipremnum aureum). Four treatments of growing media composition were tested: pure soil, ash and dung mixture in different ratios, and observed for eight weeks on the parameters of plant length, leaf area, and plant weight. Results showed that the treatment without ash mixture produced the best growth, while increasing the proportion of ash decreased plant growth performance. This is thought to be due to the heavy metal content in the ash which inhibits plant metabolism and nutrient uptake. Although the plants survived in all treatments, the effectiveness of the ash and deer manure mixture as a growing medium proved to be limited, so its use should be limited and not recommended for consumption crops. The potential utilization of ash is more appropriately directed towards non-agricultural sectors that do not come into direct contact with living things.

The vegetable creamer-based food industry produces a large amount of waste that has not been optimally utilized, reaching more than 1.4 tons per month and accumulating up to 17 tons in a period of 10 months. Disposal of this waste also requires considerable costs, so a more sustainable alternative utilization is needed. This study aims to assess the effect of applying vegetable waste creamer solution as liquid organic fertilizer on the growth and yield of mustard greens (Brassica rapa var. Parachinensis L.). The treatments used consisted of four solution compositions: 0% (control), 10%, 30%, and 50%. Parameters observed included plant height, number of leaves, and plant wet weight. The results showed that the treatment with 10% concentration gave the most optimal results on plant height and wet weight, while the highest number of leaves was obtained from the 0% treatment. High concentrations (30% and 50%) actually inhibited growth and caused plant death. These results indicate that waste creamer has potential as a liquid organic fertilizer if used in the right composition. Keyword: Vegetable Creamer, Industrial Waste, Organic Fertilizer
