Hydroxyapatite has been applied in the biomedical field as drug delivery. The drug will be absorbed onto the hydroxyapatite surface through the adsorption process. The purpose of this study was to determine the effect of initial concentration of doxorubicin (DOX) and the operating temperature on hydroxyapatite adsorption, and to determine the appropriate adsorption equilibrium model. Research began by making a solution of doxorubicin with an initial concentration of 485.83; 661.67; 884.17 mg/L. A 5 mL DOX solution was mixed with 10 mg hydroxyapatite in a beaker glass, then stirred using a magnetic stirrer at 220 rpm at 30, 40, 50 °C for 18 hours. After centrifugation, the concentration of DOX solution in the liquid was tested using UV-Vis spektofotometry. The results showed that the adsorption capacity () increased with increasing initial concentration () DOX. The value of () increased consecutively from 223.86-430.18; 231.59-434.46; 230.48-432.04 mg/g with increasing ofvalue from 485.83-884.17 mg/L at temperature of 30, 40, 50 °C. The highest value of () was obtained at 40 °C, i.e., 231.59-434.46 mg/g. It was found that the Langmuir was an appropriate equilibrium model, where the maximum adsorption capacity () values for each temperature 30, 40, 50 °C are 151.52; 163.93; 181.82 mg/g.Keywords: adsorption, doxorubicin, equilibrium model, hydroxyapatite.

This study aims to analyze the ecological character and elements of the landscape in the Harau Valley Geoheritage tourism area, Lima Puluh Kota Regency. Types of quantitative descriptive research in the form of research with methods or case studies. Data were analyzed using ovaly technique with ArcGIS application and literature study. The results of the study found that the ecological zone in the Harau Valley Geoheritage area is divided into three ecological zones, namely a low ecological zone, a medium ecological zone, and a high ecological zone. The Geoheritage of the Harau Valley is in a zone dominated by a moderate ecological zone, which is 131.48 km2 or as much as 43% of the total area of Harau District, where management in this area must be based on nature conservation to anticipate natural damage/disasters. Based on the results of landscape identification, the constituent elements of the Harau Valley Geoheritage area have natural features such as forests, waterfalls, hills, and cliffs. Meanwhile, the artificial features in the Harau Valley Geoheritage area are settlements, plantations, and agriculture.

This study aims to reveal and analyze effective strategies in increasing room occupancy rates in homestays located in Raya Tourism Village, Berastagi District, Karo Regency. This village has great potential in the tourism industry, but the occupancy rate of homestay rooms has not reached its maximum potential. Therefore, this study adopted a qualitative approach by collecting data through in-depth interviews, observation, and document analysis. The results of this study reveal that there are several strategies that can increase room occupancy rates in homestays in Raya Tourism Village. First, environmental sustainability must be improved, including waste management, natural resources, and environmental hygiene. Second, more intensive and targeted promotion is needed to increase tourists' awareness of homestays in Desa Wisata Raya. Third, quality service and personalization of the guest experience can be key factors in retaining and attracting return tourists. Fourth, collaboration between homestay owners, local government, and other relevant parties can strengthen the tourism infrastructure in the village. In this context, this study provides an in-depth insight into the strategies that can be applied to increase room occupancy rates at homestays in Desa Wisata Raya. These results can be a valuable guide for homestay owners, local government, and other stakeholders in tourism development in the region. In addition, this study also contributes to the qualitative research literature in the context of tourism and tourist village development.

This study aims to develop innovative project assessment instruments that are relevant to improving reading skills in Arabic language learning. The focus of this study is on the Grade IX Arabic Textbook published by the Ministry of Religious Affairs of the Republic of Indonesia. The background of this research is based on the need for assessment methods that can encourage students to understand texts deeply, critically, and contextually, in accordance with the demands of today's learning. This study used library research method strengthened by content analysis to explore the optimal strategies and approaches in developing project-based assessment instruments. The findings show that the instrument can be designed through activities such as text analysis, summarization, and interpretive discussion. The instrument is accompanied by an evaluation rubric that covers vocabulary understanding, text structure, content analysis, and the ability to reflect the meaning of the text in the context of daily life. This innovation is expected to improve students' reading ability while honing critical thinking skills and appreciation of Arabic texts. In addition, this instrument provides teachers with a comprehensive and measurable evaluation tool to objectively monitor student progress. This research makes a significant contribution to the development of Arabic language learning in Indonesia through an interactive and applicable approach, so that it can meet the needs of modern education in improving maharatul qiro'ah effectively and continuously.
