Abstract

This study aims to evaluate the fermentation process of white oyster mushroom baglog waste and bat guano as materials for producing multi-nutrient fertilizer, and to determine the optimal fermentation time that yields the highest levels of nitrogen, phosphate, and potassium by the 2019 Ministry of Agriculture standards. An anaerobic fermentation process was employed using white oyster mushroom baglog waste and bat guano as the primary materials, supplemented with an EM-4 bioactivator to accelerate decomposition. Fermentation was conducted over 20 days and was checked every 4 days. The research results indicate that fermentation time influences the nutrient content of the produced fertilizer. The highest nitrogen content of 2.81% was achieved on the 16th day of fermentation, while the highest phosphate content of 2.28% was recorded on the 8th day of fermentation. The highest potassium content of 3.59% was reached on the 16th day of fermentation. Based on these findings, a fermentation period of 16 days provided optimal results for nitrogen and potassium content, whereas an 8-day fermentation period yielded optimal results for phosphate content.

Abstract

Deposits of barium sulfate are a common issue in the oil and gas industry. The presence of these crystals impacts oil and gas production, causing technical problems such as inhibiting flow rate, increasing pressure in the pipe, and causing the pipe to break and be damaged. The results of this study show the formation of barium sulfate (BaSO4) crystals with the batch crystallizer method at 300 °C under the influence of the stirring rotation speed (0 rpm, 120 rpm, 240 rpm, 360 rpm, 480 rpm) and the additive concentration (0 ppm, 5 ppm, 10 ppm, 15 ppm, 2atm). In this study, the BaSO4 crystallization experiment was performed in a glass beaker using a magnetic stirrer with a stirring rotation speed to react BaCL2 and Na2SO4. The results demonstrated that adding zinc chloride (ZnCl2) and copper (ii) chloride (CuCl2) additives reduced the mass of crystals formed. The amount of barium sulfate scale that forms can be affected by the rotational speed of the stirrer. According to SEM analysis, the crystal morphology of BaSO4 was orthorhombic, indicating that this crystal shape was typical of barite crystals. While XRD analysis confirmed the formation of barium sulfate (barite) crystals, it also demonstrated that the crystals formed were solid barite crystals.

Abstract

The brine solution remaining after salt crystallization contains high levels of valuable minerals, particularly magnesium, which can be extracted and processed into magnesium chloride (MgCl₂), a compound widely used in various industrial applications. This study examines the effect of hydrochloric acid (HCl) concentration and calcination temperature on the yield of MgCl₂ synthesized from brine-derived magnesium hydroxide. Magnesium hydroxide was precipitated using sodium hydroxide and subsequently reacted with HCl solutions of varying concentrations (1N–5N) before being calcined at temperatures ranging from 350°C to 550°C. The results show that both HCl concentration and calcination temperature significantly influence the product yield. The highest yield, 80.07%, was obtained at an HCl concentration of 4N and a calcination temperature of 550°C. While increasing acid concentration and temperature generally improved yield, concentrations above 4N did not provide further benefits and instead tended to decrease efficiency. These findings highlight key processing parameters for optimizing MgCl₂ production from brine, contributing to more efficient resource utilization and environmentally sustainable mineral processing practices.

Abstract

Barium sulfate crystals are minerals responsible for scaling in piping systems. Controlling the growth of these crystals can use additives (FeCl2 and SrCl2) and varying agitation speeds. The research was to optimize the impact of additives and agitation speed on the results of crystal form using RSM through Minitab 19 with Box-Behnken Design. The optimum conditions using additive FeCl2 at a concentration of 25 ppm, a stirring speed of 120 rpm for 30 minutes, and a coefficient of determination (R2) of 90.995 provided 0.4485 gr of barium sulfate crystals. The optimum conditions, however, used SrCl2 additives at a concentration of 20.2049 ppm and a stirring speed of 459.394 rpm for 30 minutes, yielding 0.4345 g of barium sulfates with a coefficient of determination (R2) of 91.41%. The results of crystallizing barium sulfate without additives appear to be superior to those obtained with additives in terms of production. In contrast, additives of FeCl2 and SrCl2 can inhibit barium sulfate formation, resulting in a reduction in crystal mass

Abstract

This study investigates the syntesys of hydroxyapatite (HAp) from chicken bone waste, which is abundantly available due to high poultry production, using a high-temperature method. The objective of this study was to determine the effect of variations in sintering temperature (300, 400, 500, and 600°C) and sintering time (3, 4, 5, 6, and 7 hours) on the yield and Ca/P ratio of the HAp produced. The prepared chicken bone powder was first calcined at 900°C for 3 hours before sintering. The results showed that the optimal conditions were 600°C for 7 hours, characterized by a change in the sample's colour to white and a yield of 69%. XRF analysis confirmed the formation of HAp with a Ca/P ratio of 1.69. It was concluded that a sintering temperature of 600°C for 7 hours is optimal for producing pure HAp from chicken bone waste.

Abstract

Effective wound care requires dressing materials that provide physical protection while actively encouraging tissue regeneration. This research investigates the development and characterization of biocomposite nanofiber membranes composed of polylactic acid (PLA), chitosan, and cellulose, synthesized via the electrospinning method at an optimized operating voltage of 20 kV. The study aimed to identify the optimal material ratio that balances mechanical durability with surface wettability. Comprehensive evaluations included Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FTIR), water contact angle (WCA) measurements, and mechanical testing. The results demonstrate that the integration of chitosan and cellulose significantly refined fiber morphology and wettability. The optimal variant with a composition of 90:5:5 wt.% (PLA:chitosan:cellulose) achieved a WCA of 98.64°, indicating that the hydrophobicity was maintained relative to pure PLA. M orphologically, the composite fibers were uniform and bead-less, with a mean diameter reduction of 36.2% (from 517.12 nm in pure PLA to 329.68 nm). FTIR spectra confirmed successful component incorporation through characteristic amide and hydroxyl bands. Mechanically, the composite membrane exhibited a superior synergy between strength and flexibility, achieving a yield strength of 0.06 MPa and a significant elongation at break of 80.36%. These findings suggest that the 90:5:5 formulation successfully bridges the gap between mechanical durability and the high surface area-to-volume ratio required for advanced, biodegradable wound care applications.

Abstract

Limbah kulit singkong mengandung selulosa yang berpotensi untuk dimanfaatkan sebagai produk bernilai ekonomis seperti bioethanol guna bahan bakar terbarukan. Penelitian ini bertujuan untuk meningkatkan kadar selulosa dengan proses delignifikasi atau degradasi lignin pada kulit singkong menggunakan bantuan sonikasi dengan variasi daya sonikasi (0; 30; dan 60 watt) dan waktu delignifikasi (30; 50; dan 70 menit). Analisis kadar selulosa yang telah lepas dari lignin dilakukan dengan metode Chesson-Datta. Hasil penelitian menunjukkan kadar lignin tertinggi (24,954%) diperoleh pada daya sonikasi 60 watt dan waktu delignifikasi 30 menit, sedangkan kadar selulosa tertinggi (75,180%) diperoleh pada daya sonikasi 60 watt dan waktu delignifikasi 70 menit. Spektrum FTIR mengkonfirmasi adanya beberapa gugus yang dimiliki lignin (COOH, CH2, dan CH3) dimana mengindikasikan lignin masih banyak terbentuk pada daya sonikasi tersebut. Penampakan morfologi melalui uji SEM juga mengkonfirmasi adanya perubahan morfologi permukaan kulit singkong akibat penambahan sonikasi. Secara keseluruhan, kondisi optimum diperoleh pada daya sonikasi 60 watt dengan waktu delignifikasi 70 menit. Kadar selulosa yang tinggi berpotensi sebagai penghasil gula reduksi yang tinggi dan meningkatkan fermentasi bioethanol.

Abstract

This study investigates the synthesis of calcium potassium phosphate (CaKPO?) composite using acetylene waste from acetylene gas production as a sustainable calcium source. The material was produced through a dissolution-precipitation process using phosphoric acid and potassium hydroxide, with variations in the mass of acetylene waste and precipitation pH. The results demonstrate that pH strongly influences yield, elemental composition, and crystal morphology, with the highest CaKPO? yield achieved at pH 5. SEM-EDX analyses reveal that low pH conditions favor calcium-rich, irregular crystal structures, while higher pH promotes potassium incorporation and the formation of more ordered crystalline domains. Overall, the study highlights the potential of acetylene waste valorisation for developing multinutrient fertiliser materials and supports the advancement of environmentally responsible resource use in line with the Sustainable Development Goals.
