Abstract

Alkyd resin is a polymer product mostly used in paint, coating, and film making industries. This is due to the superiority of its properties as a surface coating such as flexibility, strength and durability, and adhesivity. This study made alkyd resin palm fatty acid distillate based (PFAD) and urea formaldehide butilated with variation of molar ratio of butanol 0.5-3 mgrek / mgrek. The result of residual hydroxyl from each variation is 1,25- 11,95 mgrek/g sampel. The more mole ratio of butanol the more difficult it becomes to polymer. Alkyd resin is then reacted with urea formaldehide butilated using oxalic acid catalyst. The result of the density test was obtained on the variation of 1: 0,5 and 1: 1 urea formaldehide butilated ratio with the ratio of alkyd resin and 1: 1 and 1: 2 urea formaldehide butilated with catalyst. Results obtained in the ratio of 1: 0,5 urea formaldehide butilated with 2: 1%mass alkyd resin ratio of curing time at 1.67 hours and 1: 1% mass curing time of 4.83 hours. As for the comparison of 1: 1 urea formaldehide butilated reacted with alkyd resin 2: 1% mass ratio obtained curing time of 6.43 hours and 1: 1% mass of 9.41 hours. More and more urea formaldehide butilated is used and using a catalyst to make the coating material drier faster.

Abstract

This research generated several qualitative data indicating the effects of temperature extraction and pH precipitation on spinach protein concentrates. The results shows that higher extraction temperature tend to increase protein yield. At an extraction temperature of 60°C, the spinach protein yield was 23%, while at 80°C, the protein yield increased to 28%. However, extraction temperatures above 80°C led to a decrease in protein yield due to significant protein denaturation. pH precipitation was observed to have significant influence on the quality of spinach protein. Precipitation at pH 4.5 resulted in a protein concentrate with higher brightness compared to precipitation at pH 5.5 and pH 6.5. This result indicates that acidic pH is more effective in spinach protein precipitation. Qualitative data indicated that spinach protein concentrate had good physicochemical characteristics. The protein concentrate had a greenish-yellow color and a distinctive aroma of spinach leaves. It had a neutral taste and a smooth texture. spinach protein concentrate consistency can be adjusted depends on user needs through the drying process. The results of this study demonstrated potential use of spinach protein concentrate in various food products. Spinach protein concentrate can be used as a manufacturing ingredient for a variety of food products such as pasta, cakes, and other processed products. Overall, this research provides evidence that protein extraction from spinach leaves with modified temperature extraction and pH precipitation can yield high-quality spinach protein concentrate. The results of this research will serve as a basis for the development of healthy and highly nutritious vegetable protein foods, and can contribute to the improvement of public health through the intake of highly nutritious foods.

Abstract

Penggunaan polimer, khususnya alkyd resin dalam berbagai industri semakin meningkat karena karakteristik unggulnya seperti fleksibilitas dan kekuatan. Palm Fatty Acid Distillate (PFAD) dan urea formaldehid terbutilasi adalah dua bahan baku yang umum digunakan dalam pembuatan polimer tersebut. Penelitian ini bertujuan untuk mengevaluasi sifat mekanis, terutama kuat tarik dan kekerasan dari bahan pelapis yang terbuat dari campuran alkyd resin berbasis PFAD dan urea-formaldehid terbutilasi yang ramah lingkungan. Pembuatan resin dilakukan dengan berbagai variasi komposisi bahan dan melibatkan penggunaan katalis asam oksalat, serta diikuti dengan pengujian kuat tarik dan kekerasan bahan pelapis tersebut. Hasil penelitian menunjukkan bahwa variasi dalam komposisi bahan dan penggunaan katalis mempengaruhi karakteristik mekanis material tersebut. Perubahan komposisi bahan dapat menyebabkan variasi dalam kekuatan tarik, sedangkan penggunaan katalis berpengaruh pada kekerasan material. Peningkatan jumlah urea formaldehid terbutilasi mengakibatkan peningkatan kuatan tarik pada beberapa komposisi, namun pada komposisi tertentu, kelemahan ikatan antara alkid resin dan urea formaldehid terbutilasi menyebabkan penurunan kuatan tarik. Sebagai contoh, pada rasio mol urea formaldehid terbutilasi: butanol sebesar 1:1, diperoleh hasil kuat tarik tertinggi sebesar 50 MPa, sedangkan pada rasio 2:1, hasil kuat tarik menurun menjadi 40 MPa.

Abstract

The cultivation of oyster mushrooms (Pleurotus ostreatus) and straw mushrooms (Volvariella volvacea) generates large amounts of organic waste, particularly spent growing media such as baglogs and fermented straw. This study aims to evaluate the effectiveness of combining oyster mushroom baglog waste with straw mushroom cultivation residue in producing high-quality compost. he method used was aerobic composting with seven variations of mixing ratios, supplemented with goat manure and biological activators (M-21 and molasses). The observed parameters included temperature, pH, moisture content, organic carbon content, carbon-to-nitrogen ratio (C/N), and macronutrient content (N + P₂O₅ + K₂O). The results showed that the combination of oyster mushroom waste and straw mushroom waste at a 2:3 ratio produced optimal decomposition conditions, yielding the highest compost quality in accordance with the Indonesian National Standard (SNI). The resulting compost met the quality standards based on SNI 7763:2024, particularly with respect to a maximum C/N ratio of 25, a minimum organic carbon content of 15%, a minimum macronutrient content (N + P₂O₅ + K₂O) of 2%, and a stable, near-neutral pH. These findings suggest that a proportional combination of both types of mushroom waste can serve as an effective and sustainable solution for organic waste management in support of environmentally friendly agriculture.

Abstract

The utilization of polymers, particularly alkyd resin, across various industries is increasing due to its superior characteristics such as flexibility and strength. Palm Fatty Acid Distillate (PFAD) and tert-butylated urea formaldehyde are two commonly used raw materials in the production of these polymers. This study aims to evaluate the mechanical properties, particularly tensile strength and hardness, of coating materials made from a combination of PFAD-based alkyd resin and tert-butylated urea-formaldehyde. The synthesis of the resins carried out with various material composition and involves an oxalic acid as catalyst, followed by testing the tensile strength and hardness of the coating material.. The results indicate that variations in the composition of materials and the use of catalysts affect the mechanical characteristics of the materials. Changes in material composition may result in variations in tensile strength, while the use of catalysts influences the hardness of the materials. An increase in the amount of tert-butylated urea formaldehyde leads to an increase in tensile strength in some compositions, but in certain compositions, weaknesses in the bond between alkyd resin and tert-butylated urea formaldehyde result in a decrease in tensile strength. For instance, at a mole ratio of tert-butylated urea formaldehyde to butanol of 1:1, the highest tensile strength obtained was 50 MPa, while at a ratio of 2:1, the tensile strength decreased to 40 MPa.
