Meningkatkan Hasil Belajar PAK Melalui Metode PBL Berbantu Media Audio Visual Kelas VII-A SMPN 3 Pancur Batu

The issue of low learning outcomes in Catholic Religion for seventh-grade students is attributed to the educators' tendency to use conservative teaching methods, specifically lectures. This is evidenced by the learning results of students in Catholic Religious Education at SMP Negeri 3 Pancur Batu, where only 2 out of 7 students achieved the minimum passing criteria (KKM) set by the school, which is 75. To improve learning outcomes, the researcher implemented a Problem-Based Learning (PBL) model supported by audiovisual media. The study was conducted at SMPN 3 Pancur Batu. The findings indicate that the use of the PBL model can enhance students' learning outcomes. This is demonstrated by the improvement in learning results from Cycle 1 to Cycle 2, with qualitative data showing that 14.3% of students were categorized as Developing as expected and 85.7% as Very Developing. In terms of cognitive aspects, 85.7% were classified as Proficient and 57.1% as Skilled. The conclusion of the study is that the implementation of the PBL model with audiovisual media in teaching can improve the learning outcomes of seventh-grade Catholic Religion education.

Potensi Umbi Porang (Amorphophallus oncophyllus Prain) Sebagai Pakan Ayam Broiler

Porang tuber (Amorphophallus oncophyllus Prain) contains glucomannan as a prebiotic source which can be used as animal feed to improve the performance of broiler chickens. The aim of the study was to determine the potential of porang, to analyze the nutritional content and its use as a feed ingredient for broiler chicken rations. The research was conducted at Rumah Mbacang Pancur Batu Village, from April-June 2022. This data was obtained from the results of proximate analysis at the Laboratory of Small Ruminant Instrument Standard Testing Workshop, Sei Putih, Galang. Data is processed manually and presented descriptively. The preparation of the ratio formulation consists of P0 (0% porang flour), P1 (5% porang flour), P2 (10% porang flour) and P3 (15% porang flour). The parameters studied: water content, crude protein (CP), crude fiber (CF), crude fat (EE) and NNFE. The results showed that the results of the proximate analysis on porang flour: moisture 12.92%, ash 8.22%, CP 4.19%, CF 4.79%, EE 0.62%, NNFE 69.26%. The water content and CP met the requirements according to SNI 7939: 2013, namely quality I. The conclusion from the results of formulation preparation was obtained a good composition of the formulation with nutritional content, starter phase: CP 20.08-20.59%, ME 2948.00-2985.08 Kcal/kg, CF 4.11-4.15%, EE 4.25-4.63%, Ca 0.78-0.79%, P 0.61-0.62% and finisher phase: CP 18.34-19.07 %, ME 3017.49-3050.65 Kcal/kg, CF 3.79-3.83%, EE 4.19-4.59%, Ca 0.56-0.68%, P 0.53-0.56%.

Study of Residual Soil Permeability Coefficient Post Addition of Coal Fly Ash

Residual soil is soil that is often used as barrier cover soil at the closure of B3 waste storage facilities. This is because the shear strength of the soil is quite good. The minimum value of the soil permeability coefficient (k) for barrier hoods at the closure of B3 waste storage facilities is 10-7 cm/sec. Many residual soils have a soil permeability coefficient (k) of less than 10-7 cm/sec. Because the dominant compound in coal fly ash is silica, mixing this fly ash with residual soil can reduce the value of the soil permeability coefficient (k) and is also expected to increase the shear strength value of the soil. In this study, residual soil samples were mixed with fly ash at 5%, 10%, 15%, 25% and 35% of the dry weight of the soil. This research aims to determine the effect of adding fly ash on the parameters of dry density, shear strength and soil permeability. The tests carried out were standard proctor testing, direct shear test, and Falling-Head permeability testing. The residual soil used in this research came from Hamlet I, Bintang Meriah Village, Pancur Batu District, Deli Serdang Regency. Based on standard proctor testing, the maximum density (gd max) of original soil is 1,410 gr/cm3. The largest maximum density (gd max) was obtained when adding 15% fly ash, namely 1.471 gr/cm3. In the direct shear test, the original soil cohesion value was 0.024 kg/cm² with an internal shear angle of 37.96º. In the variation of adding 15% fly ash, the cohesion value was 0.131 kg/cm² with an internal friction angle of 53.08º. Based on the Falling-Head permeability test, the original soil permeability coefficient value was 1.98 x 10-6 cm/s. The permeability coefficient value for variations in adding 15% fly ash was obtained at 8.02 x 10-8 cm/s.

STUDY OF THE COMPOSITION OF PLANTING MEDIA AND ZA FERTILIZER ON THE GROWTH AND PRODUCTION OF SAMOSIR SHALLOTS USING PVC PIPES

The research was joined by Suka Raya Village, Rampah Dua Village, Pancur Batu and Deli Serdang Districts. Research launches in July 2021 and ends in November 2021. Research objective is used for ingredient resource volume as well as the development of ZA, thereby increasing Samosir's productivity and productivity. The experimental design used in this study was a factorial randomized block design with 2 factors: the first factor, namely, the composition of the planting medium with 3 treatment levels: 100% topsoil, 75% top soil: 25% cocopeat, 50 top soil soil. %: cocopeat 50%. The second factor is ZA fertilizer with 3 treatment levels: 0 g/planting hole, 1g/planting hole, and 2 g/planting hole. Parameters observed were plant length (cm), number of leaves (strands), number of tubers, tuber diameter (mm), tuber fresh weight per plant (g), tuber dry weight per plant (g), quercetin analysis (ppm). The outcomes showed that the treatment of ZA manure with a portion of 2 g/establishing opening on plant length boundaries brought about the best plant length, tuber diameter, fresh weight and dry weight of Samosir shallots, while a dose of 1 g/planting hole could increase the number of tubers and quercetin compared to the dose of 1 g/planting hole. other. The composition of the growing media, namely top soil and cocopeat, showed an increase in the growth and quality of Samosir shallots on the number of leaves and quercetin parameters. The communication between the treatment of the sythesis of the developing media and the utilization of ZA manure didn't expand the development and nature of Samosir shallots on totally noticed factors.
