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

Halal tourism destinations have grown quite significantly, although there are still various weaknesses. This research aims to map the potential of halal tourist destinations in Pekanbaru. This mapping is expected to be a reference for Pekanbaru City to develop the concept of halal tourism in Pekanbaru. The method in this research is the study of documentation, observation, and interviews. This documentation study is also intended to obtain the concept of mapping halal tourism zoning in the city of Pekanbaru. The results show that tourist attractions in Pekanbaru have very good and friendly facilities for visitors to halal tourism which must be linked to mapping. The potential of halal tourist destinations in Pekanbaru can be grouped into historical destinations, nature, shopping centers, mosques, sports centers and restaurants. Several destinations still need to continue to develop supporting facilities to increase the comfort of visitors to halal destinations while in these destinations. The mapping that has been done has a role as a travel route recommendation that makes it easier to direct halal tourists from arrival to returning to their homes.

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

There is still a lack of clear understanding regarding the structure of the supply chain for palm oil post-harvest tools in Teratak Village, including the flow of goods, money, and information as well as the roles of each actor in that supply chain, even though the demand for these tools is quite high and important to support the productivity of oil palm plantations. This study aims to analyze and define the supply chain structure of post-harvest tools for oil palm from upstream to downstream. This study was carried out in Teratak village, Kampar Regency. Methods used are qualitative descriptive and BPMN (business process modeling notation) methods. Based on the study's results, it is known that the post-harvest tooling supply chain structure for oil palm starts with iron purchasing suppliers, independent blacksmith industries, blacksmith cooperatives, distributors, and consumers. From these factors comes the flow of goods, the flow of information, and the flow of money. All these factors are interrelated. The strategy that can be applied in this case is to optimize all relevant factors, namely iron collectors, blacksmith industry, blacksmith cooperatives, and distributors, to increase productivity in each element.
