Pengaruh Model Pembelajaran Matematika Realistik terhadap Hasil Belajar Siswa Kelas VII di MTs Dakwah Islamiyah Putri
No full textThis study aims to determine the effect of the Realistic Mathematics Education (RME) model on students' learning outcomes. A quantitative approach with a quasi-experimental design was employed. The experimental group received instruction using the RME model, while the control group was taught using direct instruction. The population of this study consisted of all seventh-grade students at MTs Dakwah Islamiyah Putri Nurul Hakim in the 2024/2025 academic year, totaling 126 students divided into four classes. The sample was selected using simple random sampling, resulting in class VII B (32 students) as the experimental group and class VII C (32 students) as the control group. Data were collected using a learning outcome test. Hypothesis testing was conducted using the t-test, which yielded a t-value (tₕitung) of 3.203 and a t-table value (ttabel) of 1.999. Since tₕitung > ttabel, the null hypothesis was rejected, indicating a significant difference in learning outcomes between students taught with the RME model and those taught with direct instruction. The effect size was calculated to be 0.801, which falls into the moderate category. This suggests that the RME model has a meaningful impact on students' mathematics learning outcomes. outcomes of Grade VII students at MTs Dakwah Islamiyah Putri
Integrasi Pembelajaran Matematika dan Nilai-Nilai Akidah Akhlak dalam Meningkatkan Karakter Religius Peserta Didik di MTs Miftahul Ishlah Tembelok
Full text linkThis research is a qualitative descriptive field research. Data collection used observation, interviews, and documentation techniques. Data processing involved data reduction, data display, and conclusion drawing. The results of this study indicate: first, not all Mathematics teachers have implemented the integration of Mathematics and moral beliefs in understanding the oneness of God through the concept of natural number sequences. This is because teachers have difficulty explaining the connection between the concept of natural number sequences and the concept of the oneness of God. Teachers have tended to explain the material purely in Mathematics without integrating it with the concept of the oneness of God. Second, not all Mathematics teachers have implemented the integration of Mathematics and moral beliefs in understanding human existence in the world through the concept of geometry. This is because teachers are not yet accustomed to linking geometric concepts with human existence in the world. Third, not all Mathematics teachers have implemented the integration of Mathematics and moral beliefs in understanding the attitude of surrender to God through the concept of fractional number sequences. This is because teachers lack adequate knowledge about the attitude of surrender to God that will be integrated with the concept of fractional number sequences. Fourth, the integration of mathematics and moral values in understanding the concepts of honesty, accuracy, and simplicity through multiplication has not been implemented by all mathematics teachers. This is because teachers have difficulty explaining the connection or relationship between the concept of multiplication and honesty, accuracy, and simplicity

Efficacy of Beauveria bassiana as a Biological Control Agent Against the Brown Planthopper Nilaparvata lugens in Rice Cultivation
Full text linkThe brown planthopper (Nilaparvata lugens) is a major pest in rice cultivation. Its population can be effectively managed through biological control using the entomopathogenic fungus Beauveria bassiana. This study aimed to evaluate the effectiveness of the entomopathogenic fungus B. bassiana in controlling N. lugens under greenhouse conditions. Applications of B. bassiana at various concentrations revealed that 10⁸ conidia/mL treatment was the most effective, achieving up to 90% mortality within 7 days post-application. This treatment also recorded the lowest LT₅₀ value of 6.736 days and the highest regression value of 0.52, indicating a rapid and effective reduction in pest population. The mortality rate exhibited an increasing trend up to day five, followed by a decline as target population diminished, with cumulative mortality reaching 90% by day seven. These findings demonstrate that a concentration of 10⁸ conidia/mL is the most optimal for biological control of N. lugens using B. bassiana, both in terms of mortality rate and speed of action. The results support the potential of B. bassiana as a promising biological control agent in sustainable pest management strategies for agricultural systems
Effect of Fermented Local Feed on Egg Quality of Laying Quail
Full text linkImproving feed efficiency through local resources is essential for sustainable quail production. This study aimed to evaluate the effect of fermented local feed on the egg quality of laying quail. A randomized block design (RBD) was used, consisting of four treatments with four replications: RA (100% commercial feed/control), RB (90% commercial + 10% fermented local feed), RC (80% + 20%), and RD (70% + 30%). Data were analyzed using ANOVA followed by Duncan’s multiple range test. The results showed that the substitution of commercial feed with fermented local feed had no significant effect (P>0.05) on yolk index, albumen index, and eggshell thickness, but significantly improved yolk color (P<0.01). At weeks 7–8, values were: yolk index 0.504 ± 0.014, yolk color 5.65 ± 0.66, albumen index 0.071 ± 0.010, and eggshell thickness 0.209 ± 0.014. At weeks 12–13, values were: yolk index 0.488 ± 0.208, yolk color 5.70 ± 0.48, albumen index 0.075 ± 0.006, and eggshell thickness 0.205 ± 0.010. It is concluded that up to 30% of commercial feed can be replaced with fermented local feed without compromising egg quality. This finding supports the utilization of local feed resources in quail farming and offers a cost-effective alternative to commercial diets
Community Structure of Echinoderms at The Intertidal Zone of Serinting Beach Special Economic Zone of Mandalika
Full text linkSerinting Beach, located within the Mandalika Special Economic Zone (SEZ), is an intertidal area with high biological potential for tourism. However, studies on its Echinodermata community remain limited. The existence of this community is crucial as an indicator of coastal ecosystem health and holds potential for developing educational ecotourism, such as reef walking tours. This research aims to analyze the species richness and composition of the Echinodermata community, along with its ecological indices (diversity, evenness, and dominance). Data was collected in March 2025 using the transect-quadrat method, employing three transects perpendicular to the coastline and 15 quadrats, each measuring 2 × 5 m². The study results revealed 21 Echinodermata species, consisting of 10 genera and 9 families from four classes: Asteroidea, Ophiuroidea, Echinoidea, and Holothuroidea. The community composition was dominated by Ophiocoma scolopendrina (43.90%), Echinometra mathaei (21.33%), and Echinometra sp. (16.77%). The diversity index (H') was 1.59; the evenness index (E) was 0.62; and the dominance index (D) was 0.28. Tripneustes gratilla populations were found in low numbers and are suspected to be under pressure due to traditional reef gleaning activities. The findings of this study are expected to serve as a basis for enviromental management and the development of educational tourism, like reef walking tours, in the intertidal zone of the Mandalika SEZ
Potential of Marine Algae as Peripheral Neuropathy Therapy: An Article Review
