Abstract

Pembakaran batubara dengan kadar sulfur lebih dari 0,23%-berat (dry basis) dengan udara pembakaran berlebih 50% pada Pembangkit Listrik Tenaga Uap (PLTU) batubara dapat menghasilkan SO2 diatas baku mutu emisi yang ditetapkan oleh pemerintah. Penyisihan gas SO2 dari gas cerobong PLTU-batubara dapat melalui proses adsorpsi menggunakan adsorben padat dengan fasa aktif seperti CuO, MgO, CaO, CeO2 yang ditempelkan pada penyangga berbasis oksida logam baik tunggal maupun campuran diantaranya adalah g-Al2O3, SiO2, TiO2. Penggunaan campuran g-Al2O3 dan SiO2 sebagai penyangga didasarkan pada beberapa pertimbangan diantaranya adalah luas permukaan dan volume pori-pori yang besar dan stabilitas termal yang baik. Campuran senyawa g-Al2O3-SiO2 dibuat dengan metode sol gel menggunakan senyawa AlCl3.6H2O dan boehmite sebagai sumber g-Al2O3 dan natrium silikat dan Siral-10 sebagai sumber SiO2. Variabel penelitian meliputi komposisi campuran g-Al2O3 dan SiO2 diperoleh dengan memvariasikan konsentrasi SiO2 dalam larutan natrium silikat (4, 6, 8 dan 10 % v/v) dan temperatur kalsinasi (550, 650 dan 750°C). Hasil penelitian memperlihatkan bahwa variasi konsentrasi SiO2 (% v/v) dalam larutan natrium silikat menghasilkan penyangga dengan sifat pori yang cenderung mirip. Kenaikan temperatur kalsinasi mempengaruhi sifat pori penyangga γ-Al2O3-SiO2. Luas permukaan, total volume pori dan radius pori rata-rata penyangga γ-Al2O3-SiO2 terbaik diperoleh pada temperatur kalsinasi 550°C masing-masing sebesar 293,724 m2/g; 1,0580 cc/g; dan 67,33Å

Abstract

The problem currently faced by Indonesian coffee in the international market is the low quality of coffee generally produced by community plantations. The quality of coffee is still low because post-harvest processing still produces random coffee, namely coffee beans produced with very simple methods and facilities, relatively high water content and still mixed with other ingredients in relatively large quantities. To improve the quality of coffee beans, the application of Good Agricultural Practices (GAP) was chosen as a framework for analyzing coffee quality, because GAP plays a crucial role in ensuring sustainable and quality agricultural practices. This study aims to determine the extent to which GAP is applied to Arabica coffee cultivation in Simalungun Regency and to find out that the application of GAP can improve coffee quality in accordance with the Indonesian Coffee SNI. The research method used is a descriptive method. The basis for selecting the research location was determined intentionally (purposive method) in Simalungun Regency. The sample in this study was coffee farmers totaling 75 respondents. Data analysis was carried out descriptively and multiple linear regression tests. From the results of the study, it can be concluded that coffee farmers in Simalungun Regency have applied GAP in cultivating coffee plants, where the highest GAP application is found in plant varieties with a score of 4.04 and planting coffee at an altitude that is in accordance with a score of 4, while the lowest GAP application is found in harvesting techniques with a score of 3.55, where there are still many farmers who harvest without considering factors that can affect the quality of the coffee beans produced. The water content of coffee beans in Simalungun Regency is around 11.27%. This is in accordance with the SNI 01-2907-2008 standard, namely a maximum water content of 12.5%. The defect value of koi beans in Simalungun Regency is predominantly quality 2, which is 56% and quality 1 is 33.33%. Coffee beans with quality 1 and 2 have good quality. The size of coffee beans in Simalungun Regency is predominantly medium, which is 69.33% and large size is 26.67%. Partially, the application of Good Agricultural Practices, namely plant varieties, coffee land suitability, altitude, fertilization, pest and disease control have a significant effect on the quality of coffee beans, while harvesting techniques do not have a significant effect on the quality of coffee beans. Simultaneously, the application of Good Agricultural Practices (plant varieties, coffee land suitability, altitude, fertilization, pest and disease control and harvesting techniques have a significant effect on the quality of coffee beans.

Abstract

This study aims to determine the effect of organic compost fertilizer and planting distance on the growth and production of soybean plants. This study uses a randomized block design (RBD) factorial with two treatment factors, namely compost fertilizer and planting distance. The first factor, compost fertilizer, consists of five levels: S0 = No treatment, S1 = 75% inorganic NPK fertilizer + 25% organic compost fertilizer, S2 = 50% inorganic NPK fertilizer + 50% organic compost fertilizer, S3 = 25% inorganic NPK fertilizer + 75% compost organic fertilizer, S4 = 100% compost organic fertilizer. The second factor is planting distance, which consists of three levels: J1 = 20 cm x 30 cm planting distance, J2 = 20 cm x 40 cm planting distance, J3 = 25 cm x 40 cm planting distance. The observed parameters were plant height, leaf chlorophyll content, root nodule count, pod count, filled pod count, empty pod count, weight of 100 seeds, seed yield per plot, wet pod weight, and dry pod weight. The results of the study indicate that the application of compost fertilizer has a significant effect on soybean plant height, leaf chlorophyll content, and root nodule count. Planting distance has a significant effect on empty pod weight, 100-seed weight, and dry pod weight. The interaction between compost fertilizer and plant spacing had no significant effect on plant height, leaf chlorophyll content, root nodule number, pod number, filled pod number, empty pod number, 100-seed weight, seed yield per plot, wet husk weight, and dry husk weight.

Abstract

This research aims to determine the effect of giving Biohayati fertilizer, giving Rhizobium bacteria and also the interaction of giving Biohayati fertilizer on soybean production. This research was carried out in Laut Tador Village, Batu Bara Regency, North Sumatra Province. At an altitude of ± 12 meters above sea level with flat topography. This research used a factorial RAK (randomized group design) with 2 treatment factors. The first factor is the provision of Bio-Biological Fertilizer, which consists of four levels, namely: B0 = No treatment, B1 = Bio-biotic solution with a dose of 18 ml/liter of water, B2 = Bio-biological solution with a dose of 20 ml/liter of water, B3 = Bio-biological solution with a dose of 22 ml/liter of water. The second factor is that the administration of Rhizobium bacteria is carried out at three levels, namely: R0 = no treatment, R1 = Rhizobium at a dose of 1.6 kg/plot (seeds mixed with Rhizobium solution), R2 = Rhizobium at a dose of 1.8 kg/plot (Rhizobium is watered in land). The results of the research show that the effect of providing Biohayati has a significant effect on soybean plant production, namely the number of pods and filled pods. The effect of giving Rhizobium bacteria has a significant effect on soybean plant production, namely the number of pods and filled pods. The interaction effect of giving Biohayati and Rhizobium bacteria on soybean production did not have a significant effect. Providing a biological solution at a dose of 22 ml/liter of water and Rhizobium at a dose of 1.6 kg/production plot to soybean plants is the best dose.
