Increasing in energy demand and limited fossil fuel reserves have driven the use of environmentally friendly alternative energy sources. This study aims to analyze the effect of pyrolysis temperature variations on the quality of biopellets made from bagasse and coffee husks. The materials were prepared in a 50:50 ratio with the addition of 15% tapioca flour as a binder. The pyrolysis process was carried out at temperatures of 450°C, 500°C, and 550°C for 120 minutes in oxygen-free conditions. The biochar resulting from pyrolysis was formed into biopellets, which were then tested for proximate composition, calorific value, and combustion rate. The results showed that an increase in pyrolysis temperature had a significant effect on the characteristics of the biopellets. A temperature of 550°C produced the lowest moisture content (8.436%), the highest fixed carbon content (62.191%), the highest calorific value (6293 cal/g), and the highest combustion rate (0.05789 g/sec). Conversely, ash content increased with rising temperature, while volatile matter content decreased. Thus, the best biopellets were obtained at a temperature of 550°C. This study confirms the potential of bagasse and coffee husks as raw materials for biopellets through pyrolysis temperature optimization to support the development of sustainable biomass energy.

The use of sengon albasia ash waste as a partial cement substitute in concrete production is carried out to reduce combustion waste and also reduce cement use. This study focuses on the use of sengon albasia wood ash waste. The use of sengon albasia wood ash as a cement substitute causes a significant decrease in the slump test value. The use of sengon albasia wood ash as a partial cement substitute in concrete mixes actually produces different results depending on the proportion. If added as much as 10%, the concrete's compressive strength actually increases, but if it reaches 20% or 30%, the compressive strength actually decreases. This occurs because this type of wood ash has a significant water absorption capacity. As a result, the water that should be used for The chemical activity occurring between cement and water is diminished, so that the bond between the cement mixture as a binder and aggregate as a filler is reduced, and ultimately the concrete's compressive strength also decreases.

This study aimed to evaluate the effect of adding Eucheuma spinosum seaweed on the quality of goat milk dodol on moisture, protein, fat, and color (L*, a*, b*). Goat milk was chosen due to its high nutritional value and better digestibility than cow milk, although its consumption in Indonesia remains limited because of its strong odor, while dodol, a traditional Indonesian confection with a chewy texture, was used as a base product to promote milk utilization. The research material was dodol made from goat milk, glutinous rice flour, sugar, and salt, with the addition of Eucheuma spinosum seaweed at concentrations of 0% (T0), 10% (T1), 20% (T2), and 30% (T3). The method used was a laboratory experiment employing a Completely Randomized Design (CRD) with four treatments and five replications. The obtained data were then analyzed using analysis of variance (ANOVA). If significant differences were found, the Duncan Multiple Range Test (DMRT) was conducted. The results showed a protein content value of 5.33%-6.37%. Fat content value of 11.96%-13.19%. Ash content value ranged from 1.49%-3.96%. Texture value ranged from 16.22 N-26.44 N. pH value ranged from 6.76-6.94. Color parameter value L* ranged from 39.65-45.39; a* 5.16-8.33; b* 21.16-22.71. Organoleptic value of texture 2.50-3.48; color 2.08-3.79; aroma 3.69-3.83; taste 3.02-3.47.

This study aims to examine the implementation of the selapanan tradition among Javanese postpartum women in Limau Manis Village, and to understand the meaning and community perceptions of this practice in the context of modern life. The selapanan tradition is part of local wisdom that has been passed down from generation to generation and has important value in postpartum maternal care. This study uses a qualitative method with an ethnographic approach, which allows researchers to understand cultural practices in depth through direct interaction with the community. Data collection techniques include participant observation, in-depth interviews with mothers who practice the tradition, community leaders, and traditional birth attendants, as well as documentation and field notes. The results show that selapanan is still preserved and practiced by the people of Limau Manis Village, although it has undergone several forms of adaptation to modern developments and modern medical guidelines. In its implementation, this tradition uses various natural ingredients such as parem (traditional body scrub), pilis (forehead concoction to refresh the eyes and mind), bengkungan (cloth to wrap the stomach), gerita (a kind of stagen or body binder), and the consumption of herbal medicine as part of physical care and body recovery. In addition to its physical aspects, selapanan also has a psychological dimension, providing emotional comfort and social support to postpartum mothers, thereby helping to prevent psychological disorders such as baby blues syndrome. This tradition serves not only as a form of traditional healthcare but also as a symbol of social solidarity and respect for local cultural values. Amidst the tide of modernization, preserving selapanan is crucial as a cultural identity that remains relevant. This study concludes that despite adjustments to medical developments, the selapanan tradition continues to play a significant role in maintaining maternal well-being and strengthening Javanese cultural values in the modern era.

This study aims to evaluate the lightfastness of organic ink formulated from purple sweet potato (Ipomoea batatas L.) pigment for screen-printing applications on 24s cotton combed fabric. The ink formulations varied the pigment amount (10, 15, and 20 grams) and solvent volume (distilled water) of 25 and 30 mL, while the binder and thickener components were kept constant. Lightfastness was assessed by measuring the change in lightness (ΔL*) before and after 24 hours of light exposure. The results showed that the formulation containing 15 g of pigment and 25 mL of solvent (P2A1) exhibited the best colorfastness, with an average ΔL* of 0.23, while the formulation with 10 g pigment and 25 mL solvent (P1A1) showed the poorest performance (average ΔL* of 1.86). A lower solvent volume resulted in higher resistance to light exposure. Moreover, using either too little or too much pigment negatively affected ink transfer and reduced lightfastness. Two-way ANOVA on log-transformed data revealed that the interaction between pigment concentration and solvent volume had a significant effect on ΔL* (p < 0.001), contributing 72.8% to the total data variation. This study confirms that achieving an optimal balance between pigment amount and solvent volume is crucial for producing organic ink with good lightfastness

Concrete typically consists of coarse aggregate, fine aggregate, cement, and water. However, cement production generates significant carbon dioxide emissions nearly equivalent to the tons of cement produced. One alternative to conventional concrete, which replaces cement as a binder, is geopolymer concrete. Geopolymer concrete utilizes fly ash or other materials containing silica and alumina as the binder. Unlike cement, which forms a binder through hydration, geopolymer concrete uses a chemical reaction with alkali activators such as Na2SiO3 (sodium silicate) and NaOH (sodium hydroxide). This study investigates the toughness of geopolymer concrete using cylindrical specimens measuring 15 cm x 30 cm with varying Na2SiO3 to NaOH ratios of 1:0.5, 1:1, and 1:1.5, cured at room temperature for 28 days. The study results show that the highest toughness was achieved with a sodium silicate to sodium hydroxide ratio of 1.5, yielding 2.7394 x 105 J/m3. Meanwhile, the toughness values for sodium silicate to sodium hydroxide ratios of 0.5 and 1.0 were 2.3748 x 105 J/m3 and 2.5821 x 105 J/m3, respectively. Thus, increasing the sodium silicate to sodium hydroxide ratio from 0.5 to 1.5 at an activator content of 0.43 affects the toughness of geopolymer concrete.

Soil stabilization is a common technique to improve the mechanical properties of the soil in term of increasing its strength and decreasing the associated settlement. The new sustainable materials have been emerged as alternative to the traditional binders such as the cement and the lime. These materials can be used in the shallow and deep soil mixing. This paper reviewed the mechanism of the soil stabilization, the traditional binder and the sever impacts on the environment, the new echo-friendly materials, deep soil mixing technique, and the geopolemerization. The results showed significant enhancement of the shear strength of the geopolymerized silt where the strength was increased by more than 6 times. This enhancement may be attributed to the developed geopolymer-jel NASH that filled the voids, surrounded and cemented the soil particles. Consequently, this matrix considered as a novel precursor for using in the soil injecting and grouting technique.

Background: Glass Reinforced Concrete (GRC) is an innovative construction material that combines glass fiber with concrete, providing high strength and durability. However, the influence of GRC mixture composition on flexural strength values has not been studied in depth. Therefore, this study aims to analyze the effect of GRC mixture composition variables, such as the ratio between glass fiber and concrete binder, on flexural strength. It is hoped that the results of this research can provide deeper insight into the use of GRC in construction and help develop more efficient and durable construction materials. Results: From the results of the discussion regarding the effect of differences in fiberglass composition on flexural strength, it was found that the addition of 2% fiber resulted in an average flexural strength of 23.01 kgf/cm2, with an increase of up to 49.77 kgf/cm2 at 1% fiberglass. However, with a fiber composition of 0.8%, the highest flexural strength was obtained at 56.84 kgf/cm2. The addition of fibers that exceed the maximum limit can reduce the density of GRC concrete so that its ability to distribute bending strength forces is reduced. Meanwhile, the effect of fly ash substitution on flexural strength shows that replacing some of the cement with fly ash by 20% can increase the flexural strength value of GRC, because the silica and alumina compounds in fly ash can speed up the hydration process. However, of the five specimens tested, none met the SNI 8299:2017 standard which requires a minimum average flexural strength of 100 kgf/cm2
