Abstract

Pig livestock feed generally competes with human needs; therefore, alternative feed is needed in the form of tamarind seeds, which contain nutrients but are also antinutrients. The technology required was to use fermented liquid feed. This study aimed to examine the effects of tamarind seeds on the nutrient digestibility growth performance of pigs. The study used a randomized blocked design (RBD) with 4 treatments and replications. In the present study, R0 = fermented liquid feed (FLF) without tamarind seeds (TS), R10 = FLF with 10% TS, R20 = FLF with 20% TS, and R30 = FLF with 30% TS. The analyzed data were subjected to analysis of variance and Duncan's test. The research variables were nutrient consumption and nutrient digestive rations. The results showed that increasing the percentage of TS in FLF had no significant effect (P>0.05) on nutrient consumption or crude fat digestibility in Landrace crossed pigs but had a very significant effect (P<0.01) on the digestibility of dry matter, crude protein, nitrogen-free extracts, crude fat, crude fiber, and ash. The conclusion is that tamarind seeds could be used in fermented liquid feed up to 30%, but it is better to use 20% to increase the nutrient digestibility of pigs. Further research regarding its use to determine the performance of carcass production is recommended

Abstract

The reaction rate topic is an abstract chemistry concept closely related to everyday life. However, students often struggle to connect theoretical concepts with real phenomena, resulting in less meaningful learning and limited critical thinking development. Therefore, learning resources grounded in local culture are needed to help students understand chemistry concepts through contextual experiences. The use of an ethnoscience-based module integrated with the GDL model in the reaction rate topic is expected to bridge scientific concepts with local wisdom and enhance students’ critical thinking skills. This study aims to develop and evaluate the validity and practicality of an ethnoscience-based module using the GDL model for the reaction rate topic in Phase F, Grade XI SMA/MA. The research employed a R&D design based on the Plomp model, consisting of the preliminary phase, the development or prototyping phase, and the assessment phase. The study was limited to validity and practicality testing, using a Likert scale questionnaire with a score range of 1–5. The validity assessment results showed an Aiken’s V value ranging from 0.93 to 0.97 across all aspects, indicating high validity. In addition, the practicality level obtained from teachers and students was 95% and 91%, respectively, indicating that the module is practical. Thus, the ethnoscience-based module using the GDL model is valid and practical for supporting learning in the reaction rate topic at the senior high school level. ABSTRAKMateri laju reaksi merupakan topik kimia yang bersifat abstrak namun memiliki keterkaitan erat dengan kehidupan sehari-hari. Peserta didik sering mengalami kesulitan dalam menghubungkan konsep teoritis dengan fenomena nyata sehingga pembelajaran menjadi kurang bermakna dan belum mampu menumbuhkan kemampuan berpikir kritis. Untuk mengatasi hal tersebut, diperlukan sumber belajar yang berorientasi pada budaya lokal agar konsep kimia dapat dipahami melalui pengalaman kontekstual. Penggunaan Modul Bermuatan Etnosains dengan Model GDL pada materi laju reaksi diharapkan dapat mengintegrasikan konsep ilmiah dengan nilai kearifan lokal serta meningkatkan kemampuan berpikir kritis peserta didik. Penelitian ini bertujuan untuk mengembangkan serta menguji validitas dan praktikalitas modul bermuatan etnosains berbasis GDL pada materi laju reaksi fase F kelas XI SMA/MA. Metode penelitian yang digunakan adalah R&D dengan model Plomp, yang terdiri atas preliminary, development or prototyping phase, dan assessment phase. Penelitian ini dibatasi hingga tahap uji validitas dan praktikalitas menggunakan instrumen berupa skala Likert dengan rentang skor 1–5. Hasil analisis validitas modul bermuatan etnosains berbasis GDL pada materi laju reaksi fase F kelas XI SMA/MA menggunakan Aikens’V, dengan nilai Aiken’s V pada setiap aspek berada antara 0,93-0,97 dinyatakan valid serta tingkat kepraktisan guru dan peserta didik masing-masing sebesar 95% dan 91% diyatakan praktis. Dengan demikian modul bermuatan etnosains berbasis GDL pada materi laju reaksi fase F kelas XI SMA/MA telah valid dan praktis digunakan sebagai sumber belajar pada materi laju reaksi di SMA/MA.

Abstract

Diabetes mellitus (DM) is one of the non-communicable diseases that is a leading cause of death worldwide, with prevalence continuing to rise year after year. One of the risk factors contributing to the increase in DM cases is the consumption of sugar-sweetened beverages (SSBs). Common types of sugar-sweetened beverages consumed by the public include carbonated drinks (soda), ready-to-drink sugary tea and coffee, fruit juices with added sugar, energy drinks, sports drinks, and flavored milk. These beverages contain high amounts of added sugar and are easily accessible to people of all ages. The purpose of this study is to determine the relationship between the consumption of sugar-sweetened beverages and the incidence of diabetes mellitus at the UPTD Puskesmas Menteng in Palangka Raya City. The research method used is correlational with a cross-sectional approach. The sampling technique is accidental sampling, with a total of 85 individuals who sought treatment at the UPTD Puskesmas Menteng in Palangka Raya City. The analysis conducted was univariate and bivariate analysis using the chi-square test. The results of the study showed that the chi-square test yielded a p-value of 0.000 < 0.05, indicating a significant association between the consumption of sweetened beverages and the incidence of diabetes mellitus at the UPTD Puskesmas Menteng in Palangka Raya City. Conclusion: There is a significant association between the consumption of sweetened beverages and the incidence of diabetes mellitus. Promotive and preventive efforts are needed to educate the community.
