Abstract

This study evaluates the use of Paper Mill Sludge (PMS) waste as a partial replacement for fine aggregate in paving block production, focusing on compressive strength and economic feasibility. PMS was incorporated at 0%, 5%, 10%, 15%, and 20% of the total fine aggregate weight. Compressive strength tests followed the Indonesian National Standard (SNI 03-0691-1996), accompanied by production cost analysis. The results showed that 5% PMS achieved the highest compressive strength of 264.23 kg/cm², about 7.7% higher than the control 258.71 kg/cm², meeting the SNI quality class B (K200) standard. Meanwhile, 10% PMS reduced production costs by 6–8% while still satisfying the minimum requirement for K200 paving blocks (category B). This demonstrates a clear trade-off between mechanical performance and cost efficiency, where 5% PMS ensures maximum strength, while 10% PMS provides adequate strength with economic benefits. At lower levels, PMS fibers improved cement–aggregate bonding and reduced voids, whereas higher dosages (>10%) disrupted hydration and lowered strength. Practically, PMS utilization offers the paving block industry a sustainable and cost-effective alternative that reduces reliance on natural aggregates, supports waste valorization, and aligns with SNI standards for applications such as parking lots.

Abstract

Sugar palm pulp is a by-product generated during the palm starch filtration process and contains lignocellulosic components. These lignocellulosic components can be separated through a delignification process. One chemical method of delignification uses an alkaline solvent. This study aimed to determine the optimal concentration of sodium hydroxide (NaOH) for maximising cellulose yield from sugar palm pulp and to characterise the resulting cellulose. The research was conducted using a completely randomised design (CRD) with four treatments and four replications. The treatments consisted of varying NaOH concentrations: K1 (1% w/v), K2 (3% w/v), K3 (5% w/v), and K4 (7% w/v). Observations were made on yield, moisture content, ash content, pH, colour, and iodine test. Data were analysed using analysis of variance (ANOVA). If the calculated F-value was greater than or equal to the tabulated F-value, the treatment effect was considered significant, and the analysis proceeded with Duncan's multiple range test at the 5% significance level. The results showed that sodium hydroxide concentration significantly affected yield, moisture content, ash content, pH, and colour. The selected treatments (3% NaOH concentration) yielded cellulose with the following characteristics: yield of 34.07%, moisture content of 6.8%, ash content of 5.99%, pH of 8.68, and whiteness degree of 36.65%. The colour coordinates were L=37.27 (low brightness) a=0.62 (slight redness) b=1.74 (slight yellowness). The iodine test resulted in a brown colour, indicating a positive reaction for cellulose.

Abstract

Oil palm empty fruit bunches are solid waste from the palm oil processing process that contains a significant amount of lignin and cellulose. Oil palm empty fruit bunches are widely found in Indonesia, especially in Riau Province. The processing of oil palm empty fruit bunches has not been effectively utilized. Therefore, the author isolated cellulose from oil palm empty fruit bunches using the organosolv method. The organosolv method is a type of isolation method that is environmentally safe than the kraft process, as it employs solvents in the form of organic chemicals, such as formic acid and acetic acid. This research was conducted by varying the ratio of the solvent solution using acetic acid and formic acid. Various solutions were employed, namely P1=20 ml formic acid+140 ml acetic acid, P2=40 ml formic acid+120 ml acetic acid, P3=60 ml formic acid+100 ml acetic acid, P4 = 80 ml formic acid+80 ml acetic acid, P5=160 ml formic acid, and P6=160 ml acetic acid. The best results were obtained in the P2 treatment with a variation of 40 ml formic acid + 120 ml acetic acid and obtained a high level of yield, namely in the P2 treatment it was 56.85%, the water content was 4.70%, the ash content was 4.84%, the acidity level (pH) was 4.67 and FTIR test results show wave peaks in treatments P3 and P6 28 waves

Abstract

Biodegradable plastic is a type of plastic made from renewable materials and can be produced using materials containing starch, such as in avocado seeds. However, starch-based biodegradable plastic has the disadvantage of low mechanical properties, such as tensile strength and elongation; therefore, it is necessary to add reinforcement, such as cellulose. One potential source of cellulose with a relatively high content is areca nut skin. This study aims to obtain the appropriate concentration of areca nut skin cellulose for the characteristics of biodegradable avocado seed starch plastic. A completely randomized design (CRD) with five treatments and three replications was used in the experimental procedure of the investigation. The treatments in this study were the addition of cellulose S1 (3 g), S2 (4 g), S3 (5 g), S4 (6 g), and S5 (7 g), and the measured characteristics were water absorption, water vapor transfer rate, tensile strength, elongation, and biodegradability. The data obtained were analyzed statistically using analysis of variance (ANOVA). The results showed that the addition of areca nut cellulose significantly affected the water absorption capacity, water vapor transfer rate, tensile strength, elongation, and biodegradability of biodegradable plastics. The selected biodegradable plastic was treatment S1 (3 g), which showed a water absorption capacity of 58.80%, a water vapor transfer rate of 17.03 g/m²/hour, a tensile strength of 30.73 MPa, an elongation of 9.31%, and biodegradability of 44.24%.
