Abstract

This study aims to determine the effect of the Cooperative Integrated Reading and Composition (CIRC) learning model on the reading comprehension ability of grade IV A students at SDN Petukangan Utara 07. This study used a pre-experimental method with a one-group pretest-posttest design, involving 30 students. The results of the pretest and posttest were analyzed using prerequisite analysis tests and hypothesis tests. The normality test was carried out using the Shapiro-Wilk test and showed that the data were normally distributed. The hypothesis test using a paired sample t-test obtained a sig. (2-tailed) result of 0.000 <0.05, so H₀ was rejected and H₁ was accepted. This indicates that there is a significant difference between the pretest and posttest scores of students. In addition, the results of the N-Gain analysis showed that the increase in reading comprehension ability was in the moderate category. Thus, the results of this study conclude that the Cooperative Integrated Reading and Composition (CIRC) learning model has an effect on improving the reading comprehension skills of fourth-grade students at SDN Petukangan Utara 07.

Abstract

This study aims to explore how the Learning Cycle 5E model can enhance elementary students’ critical thinking skills in Indonesian language learning. The research used a quantitative approach with an experimental design of Posttest Only Control Group. The subjects were 60 fourth-grade students from SDN Pondok Labu 02 Jakarta Selatan, divided into an experimental group and a control group. The instrument used was a critical thinking test consisting of four indicators: interpretation, analysis, evaluation, and inference. The results showed that the experimental group achieved an average posttest score of 85.09%, while the control group scored 67.50%. The t-test result (tcount = 5.450 > ttable = 1.325, sig = 0.000 < 0.05) indicated a significant effect of the Learning Cycle 5E model. The R Square value of 0.507 suggests that the model contributed about 50.7% to the improvement in students’ critical thinking skills. In conclusion, applying the Learning Cycle 5E model effectively supports students in developing critical and active thinking during Indonesian language learning.

Abstract

The purpose of this study is to examine the effect of brand image on customer retention with customer satisfaction as a mediating variable, as well as the role of physical evidence, among visitors of Mahoni Bangun Sentosa Tourism. This study employs a quantitative research approach using a survey method. Data were collected from 150 respondents who had visited Mahoni Bangun Sentosa Tourism at least once, selected through purposive sampling. Data analysis was conducted using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS 4 software to test the proposed hypotheses. The results of this study indicate that: (1) brand image has a positive and significant effect on customer retention; (2) brand image has a positive and significant effect on customer satisfaction; (3) customer satisfaction has a positive and significant effect on customer retention; (4) customer satisfaction is able to mediate the effect of brand image on customer retention; (5) physical evidence has a positive and significant direct effect on customer retention; (6) physical evidence does not moderate the relationship between brand image and customer retention. These findings imply that strengthening brand image and enhancing customer satisfaction are essential strategies to improve customer retention in tourism destinations, while physical evidence serves as a direct supporting factor rather than a moderating variable.

Abstract

Nusmapi Island, located in Doreri Bay, Manokwari Regency, West Papua Province, is exposed to various anthropogenic activities that may introduce pollutants transported from the mainland. Fish are commonly used as bioindicators of aquatic pollution due to their ability to accumulate contaminants through food webs. This study was conducted on Nusmapi Island from June to August 2020 to examine differences in lead (Pb) concentrations among fish species and trophic groups. Fish samples represented two trophic groups: carnivores and herbivores that feed on algae and seagrass. Pb concentrations in fish muscle were analyzed using a Shimadzu AA-6880 atomic absorption spectrophotometer (AAS). The results showed that the average Pb concentration in the carnivorous group was 0.88 mg/kg, while the herbivorous group exhibited a higher average concentration of 1.13 mg/kg. The highest Pb concentration was recorded in Siganus spinus (1.34 mg/kg), whereas the lowest concentration was found in Neoniphon sammara (0.27 mg/kg). Elevated Pb levels in sediments and seagrass around Nusmapi Island may exert continuous environmental pressure on marine biota. As Pb concentrations in these environmental compartments exceed threshold levels, they may serve as major sources of contamination entering the food chain, increasing the toxicological risk for fish occupying higher trophic levels. Keywords: heavy metal Pb, bioaccumulation, Doreri Bay   Abstrak Pulau Nusmapi merupakan daerah yang berada di kawasan Teluk Doreri Kabupaten Manokwari yang merupakan daerah yang terdampak akibat padatnya berbagai aktivitas dari daratan yang ditransport secara langsung maupun tidak langsung. Ikan merupakan organisme yang sering digunakan sebagai bioindikator untuk menilai tingkat pencemaran suatu perairan. Penelitian dilakukan pada bulan Juni - Agustus Tahun 2020. Sampel ikan yang diambil terdiri dari dua kelompok trofik, yaitu karnivora dan herbivora yang memakan alga dan lamun. Tujuan utama penelitian ini adalah menguji perbedaan konsentrasi Pb berdasarkan spesies dan kelompok trofiknya guna memahami distribusi polutan di wilayah tersebut. Daging ikan sebanyak 30 g hingga 50 g diambil pada bagian punggung, selanjutnya daging ditimbang lalu dibungkus dengan aluminium foil. Daging ikan di destruksi dan dianalisis dengan atomic absorbtion spectrophotometer (AAS). Konsentrasi Pb pada kelompok karnivora adalah sebesar 0,88 mg/kg, sedangkan pada kelompok herbivora sebesar 1,13 mg/kg. Konsentrasi tertinggi ditemukan pada Siganus spinus (1,34 mg/kg), sementara konsentrasi terendah pada Neoniphon sammara (0,27 mg/kg). Mengingat logam Pb telah melampaui ambang batas pada sedimen dan lamun akan menjadi sumber utama polusi yang masuk ke dalam rantai makanan dan pada akhirnya menempatkan ikan sebagai tingkat trofik yang lebih tinggi pada posisi rentan secara toksikologis. Kata kunci: logam berat Pb, bioakumulasi, Teluk Doreri
