Land Position in Inti Gambier (Uncaria gambier Roxb) Garden Pakpak Bharat
Distric. Supervised by Abdul Rauf and Benny Hidayat.
Evaluation of soil nutrient status is a way to be able to determine the
needs and soil nutrient management techniques to be performed on an area of
land .This study aimed to evaluate the nutrient status of the soil ( pH , N , P , K ,
Ca , Mg ) based on the position of the land in Inti Gambier Gardens Pakpak
Bharat. It was conducted at Inti Gambier Garden Pakpak Bharat district, North
Sumatera in March 2013 until June 2013. The method used in this research is
descriptive method by conducting surveys and soil sampling based on the position
of the land which is on the top of the hill , hillside and valley sectio. The results
showed nutrient soil status of total-N in Inti Gambir Garden Plants Pakpak
Bharat is likely to increase in the valley compared to the top of the hill and
hillside . As for the value of pH and P-available soil are relatively the same, while
the value of K, Ca and Mg - exchange rate tends to decrease.52 HalamanSkripsi Sarjan

Karakteristik Kimia Sampah Organik Laut Dalam Bentuk Kompos dan Biochar
No full textThe condition of Kuala Indah Beach is dominated by piles of marine organic waste such as wood branches, sea grass, piles of stranded coral, and waste remains of clam shells so innovation is needed in managing marine organic waste by processing it into biochar and compost. This study aims to examine the chemical characteristics of marine organic waste in the form of compost and biochar. This research involved taking samples of marine organic waste which was carried out at Pantai Kuala Indah, Sei Suka District, Batu Bara Regency, then making compost and biochar was carried out at the Faculty of Agriculture, University of North Sumatra, then followed by analysis of compost and biochar at the Research and Technology Laboratory of the Faculty. Agriculture University of North Sumatra, Central Laboratory Assessment Agricultural Technology (BPTP), Palm Oil Research Center Laboratory (PPKS). The results of the study showed differences in the chemical characteristics of compost and biochar of marine organic waste where marine organic waste compost had the highest value in CEC, N-total, P2O5-total and K2O-total. While the treatment of biochar marine organic waste has the highest value in the analysis of pH H2O, Moisture Content, C-Organic, C/N ratio, Mg-total, Ca-total, Cu-total, Zn-total, Mn-total and Fe-total56 HalamanSkripsi Sarjan
Micro Analysis of Structure and Elements of Biochar Made from Sawdust with Retort and Kiln Techniques
No full textThe quality of the biochar produced is determined by the type of biomass and pyrolysis method used. Meranti wood biomass has a fairly high lignin content of around 16-33%. The results and quality of biochar can be known by microanalysis of structures and elements using microscopic techniques, namely Scanning Electron Microscope (SEM) to determine the pore morphology of the biochar surface, Brunauer Emmnet Teller (BET) to determine the surface area of biochar and Fourier Transform Infrared Spectroscopy (FTIR) to find out the functional group. The purpose of this study is to find out the best pyrolysis technique in making wood-based biochar. This analysis was conducted at the Soil Biology Laboratory, Faculty of Agriculture, University of North Sumatra, Medan, and at the National Research and Innovation Agency (BRIN). The results of this study show that there are differences in the microstructure of biochar resulting from the retort and kiln techniques. The results of pH analysis showed that biochar with the retort technique was 7.53 while the kiln technique was 7.75. The results of SEM analysis show that biochar with the kiln technique has a more porous surface structure and is better than the retort technique. The results of EDX analysis obtained nutrients in the retort technique, namely 75.39% C, 21.19% O and 3.42% Cu while biochar nutrients with the kiln method consisted of 68.77% C, 11.81% O, 1.77% Cu, 9% K and 8.66% Zn. The results of the BET analysis show that the retort technique has a smaller surface area of 0.285 m²/g while the kiln method is 34.440 m²/g. The pore volume consisting of BJH adsorption and desorption in the retort technique has a smaller value, each has a value of 0.045 cc / g and 0.036 cc / g while in the kiln technique each has a value of 0.071 cc / g and 0.059 cc / g. The pore size of biochar with the retort method is larger at 24.921 Å or 2.4921 nm (meso pore) while the kiln method has a pore size of 19.366 Å or 1.9366 nm (micro pore). The results of FTIR analysis show that biochar with the retort technique has 19 wave peaks and 11 functional groups while the kiln technique has 9 wave peaks and 7 functional groups.56 PagesSkripsi Sarjan
Aplikasi Pupuk Organik Biochar (POB) dalam Mengurangi Pemakaian Pupuk Kimia pada Sifat Kimia dan Pertumbuhan Tanaman Jagung (Zea mays L.) di Tanah Ultisol
Get PDFThis study aimed to determine the effect of application biochar organic fertilizer
in the form of pellets, a combination of empty bunches of oil palm biochar, azolla
and chicken manure to reduce the use of chemical fertilizer on the growth of
maize plants (Zea mays L.) and chemical properties on ultisol soil. This research
was conducted at the Greenhouse, Research and Technology Laboratory, Faculty
of Agriculture, University of North Sumatra and the Socfin Indonesia Analytical
Laboratory (SOCFINDO) from February 2023 to August 2023. This study used a
Non-Factorial Randomized Block Design with 7 treatments and 3 replications.
Treatment factors included: POB 0 (control without POB, full dose of chemical
fertilizer), POB 1 (50 g POB, ½ CF dose), POB 2 (100 g POB, ½ CF dose), POB
3 (150 g POB, ¼ CF dose ), POB 4 (200 g, ¼ CF dose), POB 5 (250 g POB,
without CF), POB 6 (300 g POB, without CF). Parameters observed were soil
pH, organic C, available P, total N, plant height, shoot dry weight, N content, P
content, N and P absorption. The research result showed that the application of
biochar organic fertilizer at different doses had an effect significantly on soil pH,
organic C, available P, shoot dry weight, N content, N and P absorption of corn
plants in Ultisol soil except on total N and P levels. The application of biochar
organic fertilizer at a dose of 200 g and ¼ of N,P,K dose was better than other
biochar organic fertilizer doses in increasing soil-total N, plant height, shoot dry
weight, N content, N and P absorption of corn plants on Ultisol soil.87 HalamanSkripsi Sarjan
