Abstract

Tris yolk is a diluent that can be used to maintain and protect spermatozoa during storage so that they can be used in the process of artificial insemination. The length of storage greatly affects the motility and viability of spermatozoa in semen. The purpose of this study was to determine the effect of long storage of egg yolk tris diluent on the motility and viability of simental bovine spermatozoa. This research was carried out at the Banyumulek Artificial Insemination Center Laboratory, West Nusa Tenggara Province, from July to Desember 2024. The study of the effect of long storage of egg yolk tris diluent on the motility and viability of simental bovine spermatozoa used a randomized experimental method complete with four treatments and six repeats. Each treatment, namely P1, P2, P3, and P4, was carried out by mixing 0.075 ml of semen and 0.3 ml of egg yolk tris diluent stored for 24, 48, 72, and 96 hours. The data obtained were processed by variety analysis method (ANOVA) and Duncan's further test. The results showed that P1 treatment with a storage period of 24 hours resulted in the highest average motility and viability values of 63.33 ± 6.055 % for motility and 63.50 ± 6.892 % for spermatozoa viability. P4 treatment with a storage period of 96 hours still showed a good mean value with motility values of 40.83 ± 7.360 % and spermatozoa viability of 53.50 ± 12.112 %. Thus, egg yolk tris is suitable for use as a semen thinner for artificial insemination because it is able to maintain the motility and viability of spermatozoa even for a long time of 96 hours.

Abstract

Digital literacy is important for every student to have. Digital literacy needs to be trained and learned to form a young generation that is digitally literate so that they are ready to participate in the digital community with confidence in communicating, sharing and distributing knowledge in a useful and efficient way, provides readiness to adapt successfully to a changing work environment and increasing self-control as a solution to the spread of false information that continues to repeat itself and is increasing in number. This research aims to measure students' digital literacy at SMAN 1 Kesesi. The methods used were filling out questionnaires and conducting interviews. Seventy-six eleventh-grade students of SMAN 1 Kesesi, Pekalongan Residence, Central Java, Indonesia, and two biology teachers were selected as the research sample in this study. The research results showed the following aspects: Firstly, the student's digital literacy questionnaire is 71%, which is classified as moderate in digital literacy indicators including finding, using sources, selecting, evaluating, considering sources, message effects, and using data to produce work; secondly, some of the things that teachers do to train these two skills are by inviting students to search for information via Google/search engines and video searches to support the teacher's explanations and using Canva to make some presentation. Unfortunately, teachers do not train them on how to search using appropriate keywords and trusted sources. Finally, teachers must be more active and innovative in maximizing the wise use of digital media to improve students' digital literacy.

Abstract

Learning is a system consisting of several interrelated components (goals, materials, methods, learning evaluation). These components must be adjusted in the process of making a learning implementation plan. Students are guided to build their knowledge independently so that they can easily master the material obtained at school and then apply their knowledge in real life.  This research aims to develop an Electronic Student Worksheet (E-LKPD) based on Problem Based Learning (PBL) on the human respiratory system, with a focus on improving students' critical thinking patterns at SMA Negeri 5 Tanjung Balai City. The method used in this research is the 4-D model developed by Thiagarajan, which consists of four stages: Define, Design, Develop, and Dissemination. The research results showed that the developed E-LKPD received a very good feasibility assessment, with a percentage of 96.8% from material experts, 96.25% from media experts, and 96.6% from practitioner experts. From these results, it can be concluded that the PBL-based E-LKPD developed is valid, practical and effective for use in the learning process. It is hoped that this e-LKPD can increase student learning activities and help teachers convey material in a more interesting and interactive way.

Abstract

Way Umpu River, located in Way Kanan Regency, Lampung Province, is widely used by the local community and the waste products are ultimately disposed of into the river. This can cause a decrease in river water quality which can cause changes in the balance of the ecosystem, both biotic and abiotic. One of the organisms that can be used as a bioindicator is macrozoobenthos. This research aims to determine the diversity of macrozoobenthos as a bioindicator of water pollution quality. The method used was a survey method and sampling using Ekmen Grab at 6 sampling stations. Samples were taken 3 times in the left, middle and right bank areas of the river. Apart from that, water analysis was carried out in the form of physical parameters (temperature and TSS) and chemical parameters (pH, DO, COD, BOD). The data was then analyzed using the Diversity Index. The research results found 14 types of macrozoobenthos consisting of 5 phylum, namely Arthopoda, Mollusca, Porifera, Ciliophora, and Annelida. From the results of the analysis of the macrozoobenthos diversity index at station IV, it has a value of 0.56 ind/m2, which states that the location is heavily polluted. Physical and chemical factors show a significant correlation with macrozoobenthos diversity.

Abstract

This study aims to determine the effects of temperature and Aloe vera concentration on the physicochemical and organoleptic properties of mixed mulberry (Morus alba) jam. Jam is a semi-solid fruit and sugar-based product that requires a thickening agent to achieve optimal texture. Aloe vera was selected as a natural thickening alternative due to its polysaccharide content, such as acemannan and glucomannan, which can form gels, replacing expensive and import-dependent commercial pectin. The research employed a quantitative experimental method with a Completely Randomized Design (CRD), involving four treatment combinations of Aloe vera concentration (75 g and 100 g) and cooking temperature (70°C and 85°C). The parameters tested included physicochemical properties such as viscosity, fiber content, and vitamin C levels, along with organoleptic evaluations involving 25 panelists to assess viscosity and taste. Data were analyzed using analysis of variance (ANOVA) and an effectiveness test to identify the best treatment. The results showed that the combination of 100 g Aloe vera concentration and a cooking temperature of 85°C produced the best-quality jam, characterized by optimal viscosity, high fiber content, preserved vitamin C levels, and high panelist preference for viscosity and taste. This conclusion highlights the potential of Aloe vera as a cost-effective and value-added natural thickening agent for the food industry.
