Abstract

Increased public awareness for a healthy diet must be balanced with successful cultivation. Organic farming system is the right choice since it leaves all non-organic components. This study aims to identify the chemical and microbiological properties of agricultural soils that apply organic systems located in Batang Buluh Village, Pematang Johar, Deli Serdang Regency, North Sumatra. Chemical analysis was carried out at Socfindo Laboratory in Medan, including testing the pH of H2O, total P and K, C Organic, N Kjehldahl, and CEC (Cation Exchange Capacity). Soil microbiological tests were carried out at Medan Regional Health Lab including gram staining tests and biochemical tests. The results of chemical analysis from the analysis of pH H2O, P and total K, Organic C, N Kjehldahl, and CEC (Cation Exchange Capacity) at the edges and middle each obtained that was pH 5 -6, soil total P content was 0.0260% up to 0.450%, available K analysis, namely 0.200% and 0.210%, organic C content obtained results of 0.970% and 0.630%, N content using the KJehldahl method was 0.150% and 0.090%, and CEC obtained results of 14.330 me/100 and 10.090 me/100 g. Related species of Bacillus contained in the soil were Gram-positive, rod-shaped, spore-forming, aerobic or facultative anaerobic, motile bacteria with peritrichous flagella.

Abstract

Using aspirin for long time make ulcer. Using traditional medicinal plants is alternative in treating gastric ulcers. This experiment aims to determine effect of kenikir leaves extract (Cosmos caudatus Kunth.) on gastric morphology and histology decription of male white rats (Rattus norvegicus) induced by aspirin. 25 rats were divided into 5 groups, KN (control), KP (aspirin 200 mg/kgBW for 10 days), P1 (aspirin 200 mg/kgBW for 10 days + kenikir leaves extract 700 mg/kgBW for 14 days). ), P2 (aspirin 200 mg/kgBW for 10 days + kenikir leaves extract 800 mg/kgBW for 14 days), P3(aspirin 200 mg/kgBW for 10 days+kenikir leaves extract 900 mg/kgBW for 14 days). Parameters observed were morphological and histological of the gastric. Data were analyzed by oneway ANOVA test and continued with Duncan's test. The results kenikir leaves did not have a significant effect on the morphology but histologically, kenikir leaves extract had a significant effect by improving the thickness of gastric layer. It can be concluded that kenikir leaves extract can be used as an alternative to treat gastric ulcers because it can improve the thickness of gastric layer.

Abstract

The Disclosure Picking up learning model is a model for creating dynamic understudy learning techniques by self-revelation and self-examination, so that results will be gotten that will keep going quite a while in memory and are not handily forgotten by understudies. The reason for this exploration is to find out how results are impacted by utilizing the Disclosure Picking up learning model. Understudies in class VIII at SMP Negeri 17 Medan. The expression "quantitative exploration" alludes to concentrates on that current information in mathematical structure and utilize factual examination. By administering tests to determine the learning outcomes of students, information collection is completed. The trial class and the control class were the two classes used by experts. Considering the assessment shows that there are contrasts in student learning results. The typical post-test consequences of the exploratory and control classes uncover understudy learning results. The control class's average post-test score was 56.57, while the experimental class's average post-test score was 82.27. The delayed consequences of the ttest test show that the tcount regard is 12.237 and the ttable worth is 1.697 so it shows tcount > ttable then Ha is recognized. It is possible to draw the conclusion that students in class VIII at SMP Negeri 17 Medan benefit from the Discovery Learning learning model.

Abstract

Timbal termasuk ke dalam jenis logam non esensial yang sifatnya sangat beracun dan akan terakumulasi di dalam tubuh makhluk hidup karena tidak dapat dimetabolisme oleh tubuh. Penelitian ini bertujuan untuk menganalisis kandungan logam berat timbal (Pb) pada air dan daging ikan gabus di Sungai Belumai Deli Serdang. Penelitian ini menggunakan penelitian analisis deskriptif eksploratif dan komparatif dengan pendekatan kuantitatif. Penentuan lokasi pengambilan sampel dengan metode purposive sampling. Hasil penelitian menunjukkan bahwa kandungan logam berat pada air sungai Belumai Deli Serdang di setiap Stasiun berkisar 0,0517-0,1715 mg/L sudah melebihi batas baku mutu (PP RI No 22 Tahun 2021). Kandungan logam berat pada daging ikan gabus pada Stasiun 1 dan 2 sebesar <0,03 mg/Kg masih berada dibawah baku mutu, sedangkan pada stasiun 3 sebesar 49,8 mg/Kg sudah diatas baku mutu (SNI 7387:2009).

Abstract

Feeding broiler chickens will have an impact on meat quality. One feed that can be used as a substitute feed is tofu dregs, because it contains crude protein, fat, crude fiber, and BETN. The peanut content per 100 grams contains protein, fat, carbohydrates, water, ash, and of fiber, making it an excellent source of protein. The aim of this research was to determine the effect of providing additional feed with tofu dregs and green bean flour on the chemical quality of meat from 35 day old broiler chickens. This research used a Completely Randomized Design (CRD) method with 4 treatments and 5 replications. The treatment consisted of P0 (treatment feed without additional feed); P1 (90% commercial feed, 5% tofu dregs, and 5% green bean flour); P2 (80% commercial feed, 10% tofu dregs, and 10% green bean flour); P3 (70% commercial feed, 15% tofu dregs, and 15% green bean flour). Data analysis used analysis of variance (one way ANOVA) and continued with the Duncan test. The results of the research showed that supplementary feeding with tofu dregs and green bean flour had a significant effect on the water content, fat content and protein content of broiler chicken meat. Providing the best feed composition to produce quality broiler chicken meat is a commercial feed composition of 80%, additional feed 10% each.
