Abstract

Increasing microalgae biodiesel production through improvement of biomass production is reversible and is often considered economically unprofitable. This research aims to determine the effect of various levels of media salinity stress in producing microalgae strains that have higher oil content than the original population. Three species of microalgae are known to be capable of producing biodiesel, namely Chaeticheros amini, Nannochloropsis oculata and Nitzschia spp. isolated from Sekotong coastal waters, West Lombok, then cultivated in bioreactor systems for seven days with salinity stress treatment to produce strains. The resulting strains were cultivated again, but without salinity stress. Microalgae cell density was observed every day and harvested on the seventh day. The resulting microalgae biomass was extracted in stages to produce biodiesel oil. The results showed that after cultivation under salinity stress, S20, S25, S30, and S35 strains were produced from each of these species. Under salinity stress, all strains except S25 of Nitzschia spp. showed a higher maximum cell density compared to the original population and were reversible respectively. Each of the S25 strains of C. amini and N. oculata, S20 and S25 strains of Nitzschia spp., had a higher oil content than the original population, each of which was permanent

Abstract

Water quality is the quality characteristics required for certain uses of various water sources. The research aims to analyze water quality conditions, water physics (temperature, water color, depth, brightness, and current), water chemistry (pH, BOD, DO, ammonia, and phosphate), and water biology (plankton) in river flows in the village Lihung, diamond coral. This research was conducted in the river waters of Lihung Village, Karang Intan District, Banjar Regency, South Kalimantan Province. Determination of sampling points was carried out using purposive sampling. Physical and chemical parameters in the Lihung Village River that support the development of aquaculture are, temperature, pH, water color, dissolved oxygen (DO), nitrate, while parameters that do not support the development of aquaculture are, brightness, depth, current, biochemical oxygen demand (BOD), ammonia. Physical and chemical parameters still support the survival of fish, although they are still supportive, there are several parameters whose values exceed the water quality standards that have been set. Judging from the pollution index value, the Lihung River is a lightly polluted body of water. So overall the Lihung River is still good for developing fisheries cultivation. The biological parameters of plankton in the Lihung River are 3 genus variants, namely, Bacillariophyceae, Chlorophyceae, and Copepada, with the dominant plankton in the waters being the genus Bacillariophyceae, which is a class of plankton that is good for aquaculture in rivers, with a brownish green river color. Cluster 1 contains stations II and III which are similar in all water quality parameters (temperature, water color, depth, brightness, water flow, pH, DO, ammonia, BOD, phosphate and plankton). From the results of these observations, good water quality results were obtained at both stations. This cluster 2 contains station I which has significant differences in water quality from stations II and III, station I has BOD, ammonia, brightness, depth, and currents that do not support fish cultivation.

Abstract

South Kalimantan has seen a significant rise in dental and oral health issues, particularly periodontal diseases, which are prevalent among diabetic patients. This research aimed to analyze the periodontal status and the corresponding treatment needs of the Prolanis group, consisting of diabetic mellitus (DM) patients, at Sungai Ulin Health Center and South Banjarbaru Health Center, Banjarbaru City, during the second year of the study. A descriptive-analytical approach was employed to assess the periodontal tissue condition using the Community Periodontal Index of Treatment Needs (CPITN). A total of 65 respondents were examined, and the results indicated that 49.23% of the participants had tartar, while 30.78% displayed healthy periodontal conditions. Counseling on oral hygiene and scaling treatments were provided. The study emphasizes the importance of regular dental check-ups and proper oral hygiene practices, particularly in diabetic patients, to prevent further complications. Recommendations include brushing teeth twice daily and reducing the intake of cariogenic foods.

Abstract

In the education system, the application of various learning psychology theories has become the main guideline in forming effective learning strategies. This study aims to review previous studies on the application of Behavioristic, Constructivist, and Humanistic theories in science learning in order to understand the implications of each theory and the potential for integrating the three theories in increasing the effectiveness of science learning. This study is a Systematic literature review (SLR) study with a descriptive analysis approach. The data in this study came from articles that discussed the application of Behavioristic, Constructivist, and Humanistic theories in science learning. Of the 109 articles obtained through Google Search, Google Scholar, and Research Gate, it was concluded that 21 articles met the research criteria. The results of the study showed that only 21 journals discussed according to the criteria of this study, including 11 journals indexed by Sinta. The results of previous studies have made a real contribution to making decisions regarding the implementation of science learning in terms of learning psychology. The success of implementing science learning using the three theories of learning psychology in this study depends on the understanding of teachers as learners, the learning approaches used, learning models, and understanding of students' learning styles.

Abstract

This research aims to develop and implement a multicultural education program in Science and Social learning in elementary schools to shape students' characters according to the learner profile of Pancasila, especially in terms of tolerance and mutual cooperation. The ADDIE (Analysis, Design, Development, Implementation, and Evaluation) approach was used in designing this program. The results showed a significant increase in students' understanding of the values of tolerance and mutual cooperation, as seen from the comparison of pre-test and post-test scores. Students showed a more active and open attitude towards differences, while teachers felt the program helped enrich learning. The evaluation also indicated that the program needs to be adapted for different abilities of students. In conclusion, this multicultural education program proved to be effective in shaping character according to the values of Pancasila and deserves to be implemented more widely.

Abstract

Sinom is a functional drink made from turmeric and young tamarind leaves. In its development, it has gone through in vitro and in vivo tests. In its development, Sinom underwent a change in formula after mixing lime and honey. Then it underwent a change in formulation as a serum in which the turmeric ingredient was replaced with various rhizomes, such as white turmeric rhizome, temu black, meet jokes and meetups black. This research aims to determine the macro compound content and the level of preference for the sinom pre-serum functional drink, a mixture of lime and honey from various rhizomes. This research uses an experimental method with a completely randomized design, determining proximate tests using treatment; S1R1 (Tumeric Rhizome mixed with lime and honey), S2R2 (White Turmeric Rhizome mixed with lime and honey), S3R3 (Rhizome of Temu Ireng mixed with lime and honey), S4R4 (Rhizome of Temu Lawak mixed with lime and honey), SxRx (Rhizome turmeric, white turmeric, temu black, meet buffoonery) a mixture of lime and honey. Proximate testing and organoleptic preference levels were carried out.The proximate test results are; S1R1; water content (70.111%), ash content (0.713%), protein content (0.758%), pH (3.995), S2R2 (white turmeric): water content (72.355%), ash content (0.831%), protein content (0.879 %), pH(3.836); S3R3: water content (75.788%), ash content (0.605%), protein content (0.766%), pH (3.728); S4R4: water content (75.975%), ash content (0.755%), Protein content 0.884%), pH (3.826); SxRx : water content (76.617%), ash content (0.777%), protein content (0.885%), pH (3.975). Organoleptic Test Results: SxRx's most preferred taste (4.03%), SxRx's aroma (3.96%), S4R4's color (4.00%) and S2R2's texture (3.36%). The conclusion obtained from this research was that the highest average water content was in the sinom treatment using turmeric rhizomes, white turmeric, curcuma ireng and curcuma (76.617%); Ash content in sinom using white turmeric (0.831%), the highest protein content in mixed sinom using various rhizomes (0.885%), the highest pH was found in sinom using turmeric rhizomes (3.995).

It is a necessity that information technology with the power of digitalisation is experiencing accelerated development. Its application also penetrates into various fields. On the other hand, the potential of cash waqf in Indonesia is also very large. The purpose of this paper is to describe the potential of cash waqf developed through digital mechanisms, by utilizing computing technology. The institutionalization of the spirit of digital-based waqf is the focus of attention in this study. The method used is descriptive qualitative with a literature review approach. The data taken are secondary data derived from scientific journals, academic papers, books that are compatible with this study. Digital artifacts of digital waqf institution platforms are also a relevant and main source of study in this discourse. The study found that the development and transformation of digital cash waqf began in 2012 when the Indonesian Ulema Council issued a fatwa on cash waqf. The study also found that cash waqf began to grow in the community and was amplified by the presence of digital instruments in the implementation of cash waqf payments. Many waqf institutions build digital platforms through various applications, websites and other social media.

Abstract

This study aims to improve students' understanding of Pancasila values in science learning in elementary schools by applying Bruce and Weil's learning model, especially the Social Interaction Model, which emphasizes the importance of cooperation and discussion. The research was conducted on grade IV students at SDN 19 Kampung Baru Kota Pariaman using the experimental method and Static Group Comparison design. Two groups were involved: an experimental class that applied the Bruce and Weil model, and a control class that used the conventional lecture method. Data were collected through learning outcome tests and analyzed statistically. The results showed that the application of the Bruce and Weil model had a significant effect on improving the understanding of Pancasila values. The average posttest score of the experimental class was 85, while the control class reached 70. Hypothesis testing resulted in a tcount of 22.70, greater than the ttable of 1.68 at the 0.05 significance level, so the alternative hypothesis (Ha) was accepted. Bruce and Weil's model proved effective in improving the understanding of Pancasila values through active participation of students in science learning. This model is recommended as an effective alternative to integrate Pancasila values in science learning in elementary schools.

Abstract

The consistency supply of microalgae is crucial for hatchery as it plays important role as feed for larvae in the early stages. Thus, ensuring the availability of microalgae needs efficient management of feed, including the technique of biomass preservation. The purpose of this research was to observe the application of various low temperature to preserve Nannochloropsis oculata as feed. The source of N.oculata was filtered through a double set of 0.45 micron of cartridge which then preserved based on treatments A (5°C); B (-20° C); and C (15°C) for 30 days. After 30 days of preservation, each treatment as inoculum were cultured in the volume of 2 liter. Initial density of N.oculata was 23-24x106 cells.ml-1 placed into medium consisted of sterile sea water salinity 30 ppm, KW21™ fertilizer dose 1 ml.l-1. Culture environment was set with illumination 3.000-4.000 lux, homogenized with constant aeration, with 15 days of culture period. The result showed that on the days 9, cell density on treatment A, B and C were significantly different each other (sig 0.001), where treatment A had the highest cell density at 57.42±6.95x106 cell.ml-1, then followed with treatment C with 38.33±2.08x106 cell.ml-1 and B with 20.33±5.35x106 cell.ml-1. The use of low temperature as preservation for N.oculata could help low-middle hatchery with remoted area to maintain the sustainability of N.oculata stocks.
