Abstract

Corn cobs as waste organic agricultural having content±45% cellulose. Cellulose is a biopolymer that can be converted into glucose. Glucose can be produced by A.niger and T.ressei through fermentation process. Glucose in generate can be developed to become fructose syrup through a process isomerisasi with enzymes glucoisomerase prodused by Streptomyces Sp. This research using corn cobs yellow as a source of cellulose for the production of fructose. The purpose of this research is to find concentration fructose syrup obtained from fermentation process. Convertion cellulose be done in enzimatis use A.niger and T.ressei through the fermentation process by adding Saccharomyces cerevisiae. The process continues with isomerization use Streptomyces Sp. The process isomerization done with variations time is 1,2,3, and 4 hour and variation pH 6,7, and 8. Analysis concentration glucose and fructose of fermentation product performed with GCMS. The highest result obtained was fermentation 1 hour at pH 6 with glukoce 6,7% and fructose 16,22%.

Abstract

Corncob contains xylan content of 12.4 - 12.9% which can be converted to xylitol [1]. Xylitol significantly reduces the population of Streptococcus mutans (S. mutans) in saliva compared with fluoride [3]. The effectiveness of xylitol from corn cobs waste is an antibacterial substance of S. mutans in safe and water-soluble mouthwash. The purpose of this research is to produce xylitol from corn cobs waste and to test the xylitol inhibition as anti bacterial in S. mutans bacteria. The xylitol extraction method of corncob using aqueous sulfuric acid is 0.25; 0.5; 0.75 and 1.0%. The extraction time was then varied from 15, 30, 45, 60, 75 and 90 min. The results showed xylitol compound from corn tuna waste was highest at 0.25% sulfuric acid concentration with 30 minutes hydrolysis time of 249.7 ppm and the lowest at 0.75% acid concentration and hydrolysis time of 90 minutes is 5.6 ppm. Xylitol compounds can be obtained from corn cobs waste has the value of inhibitory growth of S. Mutans bacteria in all variations of acid concentration (H2SO4) and hydrolysis time is 100%.

Abstract

The purpose of this study was to determine the temperature, time and the optimum size of the pyrolysis process to yield liquid smoke, and to know the grade of liquid smoke. Pyrolysis process were done by varying the temperature 350oC, 400oC, 450oC, 500oC, the time variation of 30 minutes, 60 minutes, 90 minutes, 120 minutes, 150 minutes, 180 minutes and a variety of fine size (3/8 inch), medium (1 inch), coarse (1.5 inches), after the analysis of pH, specific gravity, acid tertitrasi and total phenol content analysis. Liquid smoke that optimum results are calculated to determine whether the economic feasibility of this research can be continued at the industrial stage. The research showed the optimum temperature of 400oC at a yield of 45.5%, the optimum time of 120 minutes resulted in a yield of 46% and smoother optimum size at a yield of 47%. Total acid is between 6.8054% - 7.2746%, pH between 1.8 to 1.9 with phenol levels between 3.4456% - 4% in 1569 to produce liquid smoke to grade 4.

Abstract

This study aims to analyze the implementation of the debate technique in improving students’ speaking skills and to assess the outcomes after its application. Conducted in class XI A3 of SMAN 19 Tangerang Regency, the research involved 36 students and employed Classroom Action Research (CAR) through two cycles. Data was collected via observation, documentation, and speaking tests, and analyzed using both quantitative and qualitative methods. The population of this research is 180 students in the XI science classes, while for the samples, the researcher selected 36 students from XI A3 because this class is considered to be the most passive one compared to others . xxxxx The findings revealed that the debate technique was effective in enhancing students’ speaking performance, self-confidence, and classroom interaction. The pre-test score was 62 . These improved to 68.67 in the in cycle one. In the cycle 2, students exceeded the minimum passing score, achieving 76.89. The results indicate that debate is a beneficial and engaging technique for fostering speaking skills in an EFL context. It is recommended that teachers integrate debate activities into their instruction to encourage student participation, critical thinking, and oral communication. Yet, the improvement on the pronunciation needs more exploration for the next research.
EFEKTIVITAS PENDIDIKAN KESEHATAN TERHADAP PENINGKATAN PENGETAHUAN MASYARAKAT CIMACAN TERHADAP STUNTING Mahyati, Mahyati; Aprillya Andriyansyah, Pasha; Kartika Winata, Rieke; Anggraeni, Shelpi; Az Hara Ariesta, Syafira; Inriyana, Ria; Kusuma Dewi, Endang

Abstract

Stunting merupakan permasalahan kesehatan yang berdampak jangka panjang bagi pertumbuhan anak. Upaya peningkatan pengetahuan masyarakat, khususnya wanita usia subur (WUS), menjadi langkah preventif yang penting. Pengabdian kepada Masyarakat ini bertujuan untuk mengevaluasi efektivitas pendidikan kesehatan terhadap peningkatan pengetahuan WUS mengenai stunting. Metode PkM ini adalah Pendidikan masyarakat melalui penyuluhan kesehatan dengan sasaran WUS sejumlah 16 orang, kegiatan meliputi perencanaan, pelaksanaan, dan evaluasi. Penyuluhan terdiri dari tiga sesi, yaitu pengisian pre-test, pemaparan materi dan diskusi, serta pengisian kuosioner post-test. Data diolah dengan uji t-test berpasangan untuk melihat perubahan skor pengetahuan yang didapat. Hasil penelitian menunjukkan peningkatan skor rerata dari pre-test (M=71,875; SD=16,419) ke post-test (M=83,125; SD=9,465). Analisis statistik menunjukkan adanya perbedaan yang tidak signifikan (p=0,017 > 0,05), namun peningkatan skor rata-rata mengindikasikan adanya perbaikan pemahaman peserta. Temuan ini menunjukkan bahwa pendidikan kesehatan berkontribusi terhadap peningkatan kesadaran WUS mengenai stunting. Diperlukan inovasi edukasi yang lebih interaktif untuk meningkatkan efektivitas intervensi dalam pencegahan stunting.

Abstract

Seiring berkembangnya teknologi, sectio caesarea tanpa indikasi medis semakin banyak dilakukan di Indonesia. Namun, hal ini masih menjadi permasalahan dalam pandangan hukum islam dan kesehatan. Penelitian ini bertujuan untuk menggali sudut pandang hukum Islam melalui ulama serta pandangan tenaga kesehatan mengenai tindakan sectio caesarea tanpa indikasi medis. Diharapkan penelitian ini dapat memperkuat dasar hukum dalam pengambilan keputusan klinis terkait praktik persalinan, serta memberikan wawasan yang jelas mengenai legalitas dan etika tindakan, baik dari perspektif agama maupun medis. Penulis memakai pendekatan kualitatif melalui analisis kualitatif tematik, bertempat di Kabupaten Sumedang. Pengumpulan data dilakukan melalui wawancara mendalam terhadap partisipan yang berkaitan dengan fenomena judul yang diangkat. Adapun partisipan dari penelitian ini yaitu 2 tokoh ulama dan 3 tokoh ahli medis, yaitu dokter spesialis kandungan, bidan, serta perawat yang berdomisili di Kabupaten Sumedang. Hasil dari penelitian menunjukkan bahwa semua tenaga kesehatan berpendapat bahwa tindakan sectio caesarea tanpa indikasi medis tidak dianjurkan sehingga diupayakan tidak dilakukan karena mempertimbangkan risiko yang mungkin timbul dari tindakan tersebut akan lebih banyak dibandingkan persalinan normal. Namun selanjutnya dokter berpendapat bahwa tindakan ini tidak dianggap ilegal atau melanggar kode etik selama pasien memperoleh informasi dengan komprehensif terkait tindakan tersebut. Selanjutnya, kedua ulama berpendapat bahwa tindakan sectio caesarea tanpa indikasi medis termasuk haram hukumnya dalam islam karena dianggap lebih memilih mudharat yang sudah jelas adanya sedangkan ia bisa memilih yang banyak maslahatnya yaitu persalinan normal. Maka dapat disimpulkan bahwa tindakan sectio caesarea tanpa indikasi medis tidak diperbolehkan menurut pandangan islam dan tidak dianjurkan menurut pandangan tenaga kesehatan.
