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.

Abstract

This study uses the Multi-Dimensional Scaling (MDS) method to analyze the sustainability status of five waterfall tourist destinations in Banyumas Regency and to guide future development strategies. This study is very important, given the limited research on the sustainability of Curug tourism, which faces challenges such as a declining number of visitors and a low economic contribution to Regional Original Revenue (PAD), at only 6.3%. Using five dimensions—Ecology, Economic, Socio-Cultural, Legal and Institutional, and Infrastructure and Technology—key findings show that overall sustainability status is in the "Moderately Sustainable" category. Curug Gede recorded the highest average score (54.59) and showed the best balance between the pillars, while Curug Ceheng was the only one categorized as "Less Sustainable" (44.746). Sustainability efforts are strongly supported by the Ecology and Legal and Institutional dimensions, but are consistently hampered by low scores on the economic and Socio-Cultural dimensions across locations. The leverage analysis highlights five attributes that are highly sensitive and require priority interventions: waste and emissions management (Ecology), tourism market potential (Economy), access for all (socio-cultural), implementation of natural resource surveillance (legal and institutional), and public transportation and technology-based promotion (infrastructure). These findings offer practical, long-term strategies to support holistic, sustainable development in the Curug tourism sector in Banyumas.

Abstract

The application of the Domestic Component Level (DCL) within the infrastructure construction sector constitutes a strategic policy undertaken by the government to promote the utilization and development of domestic products while reducing reliance on imported goods. In high-rise building projects, the assessment of DCL extends beyond material usage to include the contribution of local services and labor, as reflected in the Unit Price Analysis of work activities. This study is intended to determine the DCL value, the Company Benefit Weight, and the combined Domestic Component Level-Benefit Weight (BMP) value. A quantitative research approach is employed, utilizing secondary data such as the Cost Budget Plan (RAB), Unit Price Analysis (AHS), technical specifications, and unit price lists. The findings indicate that the DCL value reaches 80%, while the BMP value is 3%, resulting in a combined DCL and BMP value of 83% for the Pingit Police Dormitory Apartment construction project. This outcome surpasses the minimum DCL requirement of 25%, indicating that the project is not subject to further evaluation procedures or financial penalties.

Abstract

This This study aims to synthesize calcium magnesium nitrate fertilizer (CaMg(NO?)?) from calcined dolomite and to evaluate the influence of dolomite mass and stirring time on the resulting calcium (Ca) and magnesium (Mg) content. Dolomite was selected as the primary raw material due to its wide availability in Indonesia and its naturally high Ca and Mg composition. The experimental procedure consisted of two main stages: thermal calcination of dolomite at 800°C for 4 hours, followed by a reaction with 100 mL of 68% nitric acid at 35°C under constant stirring at 300 rpm. The dolomite mass was varied between 5 and 25 g, while the stirring time ranged from 15 to 75 minutes. Product characterization was conducted using X-ray fluorescence (XRF) to quantify CaO and MgO contents. The results indicate that prolonged stirring enhances the dissolution of mineral components, leading to improved calcium recovery, although the effect of increasing dolomite mass does not exhibit a strictly proportional trend. The optimum condition was identified at 20 g of dolomite and 60 minutes of stirring, yielding 82.05% CaO and 0.88% MgO after normalization. The CaO content satisfies the minimum requirement specified in SNI 02-2806-1992 (?26%), whereas the MgO content remains below the threshold established by European Communities regulations (1994). Overall, the synthesized product is more appropriately categorized as a calcium-based fertilizer, given the predominance of calcium over magnesium in the final composition. These findings highlight the potential of calcined dolomite as a viable feedstock for nitrate-based fertilizer production, although further optimization is required to enhance magnesium incorporation.

Abstract

Hydroxyapatite (HA) is a bioceramic widely used in biomedical applications due to its excellent biocompatibility and bioactivity. This study aims to synthesise hydroxyapatite from rice field snail shells (Pila ampullacea) using the precipitation method and to evaluate the effects of phosphoric acid (H?PO?) concentration and heating time on the synthesised hydroxyapatite's characteristics. The synthesis was conducted by varying H?PO? concentration from 0.25 to 2 M and heating time from 1 to 3 hours at a calcination temperature of 800°C. The resulting hydroxyapatite was characterized by SEM-EDX, XRF, XRD, and FTIR analyses, and the Ca/P ratio was optimized using Response Surface Methodology (RSM). SEM-EDX analysis revealed porous and agglomerated surface morphology, indicating successful thermal decomposition of calcium carbonate into calcium oxide                precursor. XRF results showed that increasing H?PO? concentration and heating time significantly reduced the Ca/P ratio toward the stoichiometric value of                hydroxyapatite (1.67), with optimum conditions achieved at 1.5–2 M H?PO? and         2–2.5 hours heating time. XRD analysis confirmed the formation of crystalline              hydroxyapatite with an average crystal size of 14.62 nm and crystallinity degree of 81.23%. FTIR spectra identified characteristic phosphate functional groups,           confirming hydroxyapatite formation. The RSM optimization demonstrated that both H?PO? concentration and heating time significantly influence the Ca/P ratio. These findings indicate that rice field snail shells have strong potential as a                 sustainable and cost-effective alternative calcium source for hydroxyapatite synthesis in biomaterial applications.

Abstract

This study analyzes the productivity and operational efficiency of heavy equipment in the South Cross Route (JLS) Lot 3 Blitar road construction project. A quantitative descriptive approach was employed using primary data obtained from field observations and time-motion studies, as well as secondary data including project schedules, equipment specifications, and cost data. Equipment productivity was calculated to determine actual execution time and rental costs. The results indicate that earthworks, embankment, aggregate base course, and AC-BC asphalt works achieved higher efficiency than planned, as reflected in shorter execution times and lower operational costs. However, AC-WC asphalt work experienced significant inefficiency due to material supply disruptions and equipment idle time. Productivity imbalance among equipment units was identified as the main factor affecting system performance. This study highlights the importance of synchronizing equipment capacity and ensuring continuous material supply to minimize idle time and improve project efficiency.

Abstract

Mellorine is a frozen dessert similar to ice cream that uses vegetable oil as a substitute for milk fat. This study utilized honey mango peel as a raw material for mellorine production. The research aimed to determine the effect of carboxymethyl cellulose (CMC) and virgin coconut oil (VCO) addition on the physicochemical and sensory characteristics of honey mango peel mellorine, as well as to determine the best treatment combination that produces mellorine with desirable physicochemical quality and consumer acceptance. This study employed a quantitative method using a Completely Randomized Design (CRD) with a two-factor factorial arrangement and two replications. The first factor was CMC concentration (0.4%, 0.7%, and 1%), while the second factor was VCO concentration (5%, 7.5%, and 10%). The observed parameters included fat content, crude fiber, overrun, melting rate, total soluble solids, viscosity, emulsion stability, antioxidant activity, vitamin C, and sensory properties. The results showed that CMC had no significant effect on fat content, while VCO significantly affected fat content. Both CMC and VCO had no significant effect on crude fiber content. However, the addition of CMC and VCO significantly affected overrun, melting rate, total soluble solids, viscosity, and emulsion stability. In sensory evaluation, only texture showed a significant effect, whereas color, aroma, and taste were not significantly different among treatments. The best treatment was obtained from the addition of 1% CMC and 10% VCO, producing mellorine with good overrun, slower melting rate, smooth texture, and acceptable sensory characteristics. The product also contained high antioxidant activity and vitamin C. These findings indicate that the combination of CMC and VCO improved the physicochemical stability and consumer acceptance of honey mango peel mellorine.

Abstract

Chrysanthemum is a highly valuable commercial cut flower. Providing supplemental lighting at an optimal height is crucial to enhancing plant growth and flower quality. This study evaluated the effects of light color, lighting height, and their interaction on the growth and yield of chrysanthemum (Dendranthema grandiflora). The experiment was conducted in a greenhouse at Agro Pudak Lestari Farm, Buleleng, Bali, utilizing a factorial Randomized Block Design (RBD) with two factors: light color (white [Wp], purple [Wu], and yellow [Wk]) and lighting height (1 m [T1], 2 m [T2], and 3 m [T3]), replicated three times. Although the interaction between the two factors had no significant effect on any of the observed variables, each factor individually exhibited significant to highly significant effects. Yellow light (Wk) yielded superior plant growth, stronger stems, enhanced visual quality, and the highest economic fresh weight at 77.91 g—a 30.9% increase compared to white light (Wp). Meanwhile, a lighting height of 2 meters optimized growth variables by 4.7–7% and increased economic fresh weight by 15.1%. Consequently, applying yellow light at a height of 2 meters is highly recommended to maximize the growth and yield of chrysanthemum cut flowers.
