Analisis kesadahan dan TDS Air Tanah Dangkal daerah pangale dan tande Kota Majene
Full text linkkualitas air yang baik sering kali sulit didapatkan terutama di daerah yang memiliki kandungan kapur tinggi dalam air tanah. Air yang mengandung kapur, atau dikenal sebagai air keras, dapat berdampak negatif pada kesehatan, seperti menyebabkan gangguan pencernaan dan iritasi kulit. Selain itu, air kapur juga dapat merusak peralatan rumah tangga dan infrastruktur air karena terbentuknya kerak kapur. Tujuan dari penelitian adalah untuk mengetahui tingkat kesadahan dan Total Dissolved Solid (TDS) pada air tanah dangkal. Metode yang digunakan adalah metode eksprimental dengan mengukur langsung kualitas air di lapangan. Dari hasil penelitian diperoleh nilai kesadahan untuk daerah pangale pada titik 1 adalah 519.55 mg/L, titik 2 adalah 517.53 mg/L, titik 3 adalah 727.15 mg/L. Untuk TDS dilokasi pangale diperoleh titik 1 adalah 993 ppm, titik 2 adalah 955 ppm, titik 3 adalah 773 ppm. Sedangkan untuk daerah tande diperoleh kesadahan di titik 1 sebesar 352.25 mg/L, titik 2 sebesar 322.19mg/L, titik 3 sebesar 427.84mg/L dan TDS diperoleh titik 1 adalah 684 ppm, titik 2 adalah 913 ppm, titik 3 adalah 1018 ppm
Inovasi Mie Ikan Penja dengan Subtitusi Tepung Kelor dan Tepung Cassava Sebagai Alternatif PMT Balita Gizi Kurang
No full textUndernutrition remains one of the major causes of infant mortality in Indonesia. Providing supplementary feeding (PMT) is one of the key strategies to combat this issue. This study aimed to examine the innovation of penja fish noodles substituted with moringa leaf flour and cassava flour in three formulations: P1 (0:20:80), P2 (3:20:80), and P3 (10:20:80), and to evaluate their acceptability and nutritional content. The research was an empirical laboratory-based study conducted over four months. Organoleptic tests were carried out in Kelurahan Rangas, Majene, and nutritional analysis was performed at the Health Laboratory Center in Makassar. The data were analyzed using a Completely Randomized Design (CRD) and ANOVA. Organoleptic parameters included color, aroma, taste, and texture, while nutritional tests measured fat, protein, carbohydrate, and iron content. The results showed that formula P2 (3:20:80) was the most preferred by consumers and had a balanced nutrient composition. Although some nutrient components did not differ significantly, the substitution improved carbohydrate content. In conclusion, this innovation has the potential to serve as an alternative PMT for undernourished toddlers. Further studies are needed to evaluate its long-term effects and feasibility for broader implementation

Balancing Structure and Autonomy: EFL Tutors’ Psychological Perceptions in Web-based Distance Learning
No full textThe rapid expansion of web-based distance learning (WBDL) in higher education has significantly changed English as a Foreign Language (EFL) instruction, particularly in universities that implemented a distance learning system where flexibility and technological integration are vital. While most research focuses on technology or students, this study explores how English as a Foreign Language (EFL) tutors at an Indonesian university perceive web-based distance learning. Employing a descriptive qualitative design within an interpretive paradigm conceptually grounded in Qiong's (2017) six-dimension framework, the study analyzes interview data from two experienced tutors. The tutor was intentionally chosen to facilitate an in-depth, rich, and detailed comparative analysis of their subjective psychological perceptions, aligning with the study's interpretive paradigm, which seeks depth over generalizability. The interviews were recorded and transcribed, then thematically analyzed with multiple rounds of open coding, thematic grouping, and interpretive synthesis in order to establish how tutors' perceptions reflected their negotiation between institutional expectations and professional agency. The results illustrate a key tension reflecting the study's central dichotomy: one tutor prioritizes institutional structure and professionalism, while the other emphasizes pedagogical autonomy and learner-centeredness. The study concludes that successful web-based distance learning requires a dynamic psychological balance between the system and autonomy. Practically, these findings suggest that institutions must move beyond mere technical training and provide robust psychological and affective support, recognizing tutors as critical agents in negotiating this balance rather than just as system operators
Multi-Modal Learning Strategies and EFL Speaking Accuracy: Insights from a University Setting
No full textThis study investigates the effectiveness of the SAVI (Somatic, Auditory, Visual, Intellectual) method in enhancing the speaking ability of third-semester EFL students at the Muslim University of Indonesia. The research employed a pre-experimental design, utilizing pre-test and post-test assessments to evaluate changes in students’ speaking performance. Thirty-two students participated in the study, with speaking accuracy measured in terms of pronunciation, grammar, vocabulary, and fluency. The findings revealed significant improvements in students’ speaking ability after the SAVI intervention. The mean pre-test score of 2.59 increased to 5.25 in the post-test, and statistical analysis confirmed a significant difference between the two assessments. Students exhibited enhanced articulation, grammatical accuracy, and lexical richness, alongside greater confidence and willingness to participate in oral activities. These results indicate that multi-sensory learning strategies can foster holistic development and strengthen communicative competence, surpassing traditional lecture-based approaches in promoting effective language use. The study highlights the practical implications of integrating SAVI methods into EFL instruction, emphasizing the value of active engagement, real-time feedback, and interactive classroom practices. The findings suggest that educators can achieve measurable improvements in speaking proficiency by employing sensory-based pedagogical interventions. Additionally, the research provides insights for curriculum designers and teacher training programs, advocating for flexible, learner-centered approaches that align with modern communicative language teaching principles

Species Diversity and Distribution Patterns of Epiphytic Orchids (Orchidaceae) in Bukit Pasapa Kurrak, Mamasa, West Sulawesi, Indonesia
Full text linkBiodiversity refers to the variety of living organisms, encompassing genetic, species, and ecosystem diversity within a particular area. Epiphytic orchids are orchids that grow on other plants but are not parasitic, as they only attach to the trunks, branches, or twigs of living or dead trees without deriving nutrients directly from their hosts. This study aimed to analyze the diversity and distribution patterns of epiphytic orchid species in Bukit Pasapa Kurrak and to explore their implementation as a biological learning resource. This research employed a quantitative approach using an exploratory survey method. Sampling was conducted using a purposive sampling technique. The collected data were analyzed by calculating several ecological indices, including the Important Value Index (IVI), Shannon–Wiener diversity index (H’), Simpson dominance index (C), evenness index (E), and Morisita’s index of dispersion (Id). The results showed that the diversity of epiphytic orchid species in Bukit Pasapa Kurrak was categorized as moderate, with a Shannon–Wiener diversity index of H’ = 1.66. The distribution pattern of epiphytic orchids in the study area was classified as random, with a Morisita index (Ip) of 0.04. Furthermore, validation results from two expert validators indicated that the developed learning resource was highly valid and feasible to implement as a biology learning resource
