Studi Perbandingan Kandungan C, N, C/N, P dan K di dalam Kompos Kembang Bulan (Tithoni diversifolia dan Daun Nippon (Euphatorium odoratum L.) dengan Variasi Waktu Pengomposan
No full textIt has been carriet out a comparative study on C, N, C / N, P, and K content in
Kembang Bulan (tithoni diversifolia) and Daun N ippon (euphatorium odoratum
L.) manure in which manuring times were variated. Sample were taken randomly
from Kabupaten Karo, Kabupaten Dairi and Kabupaten Humbang Hasudungan.
They were cut into small species, dried and mixed in equal weight proportion.
Manuring process was carried out by adding the bran and pig’s manure and using
EM4 as starter for the manuring duration of 0, 3, 6, 9, 12, and 15 days. C-organic
content was by Walkey Black method, total-N by Kjehldahl method, total-P by
spectrofotometric method and K content by tomic Asbsorption Spectrofotometre.
The similar procedure of determination is used for both types of sample either
before or after manuring process. Results on this study show that on the optimum
manuring process, that is in 15 days, the C/N ratio for Kembang Bulan manue is
10.08 and for Daun Nippon manure is 10.48. These values show that both product
have good quality. For Kembang Bulan manure, it was found that C-organic
content is 25.50 %, total-N is 2.53 %, total-P as P2O5 is 0.7668 % and K as K2O
4.169 %. For Daun Nippon manure, it was found that C-organic content is 25.01
%, total-N is 2.39 %, total-P as P2O5 is 0.7377 % and K as K2O 3.372 %. It can be
concluded that Kembang Bulan and daun Nippon plants can be used as raw
material for organic fertilizer because the manure obtained by using both plants
fulfilling the standart quality of compost according to SNI 19-7030-2004Telah dilakukan penelitian tentang studi perband ingan kandungan C, N, C/N, P,
dan K di dalam kompos Kembang Bulan (tithoni diversifolia) dan Daun Nippon
(euphatorium odoratum L.) dengan variasi waktu pengomposan. Pengambilan
sampel dilakukan secara acak dari Kabupaten Karo, Kabupaten Dairi, dan,
Kabupaten Humbang Hasudungan, dirajang lalu dicampur dengan perbandingan
berat yang sama. Sampel terlebih dahulu dikeringkan sebelum proses
pengomposan dengan penambahan kotoran babi dan dedak serta menggunakan
EM4 sebagai starter dengan interval waktu pengomposan 0, 3, 6, 9, 12, dan 15
hari. Penentuan C - organik dilakukan dengan metode Walkey Black, N itrogen
(N) Total dengan metode Kjehldahl, Posfor (P) sebagai P-Total dengan
menggunakan metode Spektrofotometri, dan Kalium dengan Spektrofotometer
Serapan Atom (SSA). Prosedur yang sama dilakukan terhadap kedua sampel
Kembang Bulan dan Daun N ippon sebelum dan sesudah pengomposan. Dari hasil
penelitian menunjukkan bahwa pengomposan yang optimum yaitu hari ke-15
diperoleh C/N Kembang Bulan 10,08 dan Daun Nippon sebesar 10,48 yang telah
mendekati C/N yang baik yaitu 10 – 20. Untuk Kembang Bulan C – organik
diperoleh sebesar 25,50 %, nitrogen - total 2,53 %, C/N sebesar 10,08, posfor-
total sebagai P2O5 sebesar 0,7688 % dan K sebagai K2O sebesar 4,169 %.
Sedangkan untuk Daun Nippon kadar C – organik diperoleh sebesar 25,01 %,
nitrogen-total 2,39 %, posfor-total sebagai P2O5 sebesar 0,7377 % dan K sebagai
K2O sebesar 3,372 %. Dapat disimpulkan bahwa Kembang Bulan (tithoni
diversifolia) dan Daun Nippon (euphatorium odoratum L.) dapat dimanfaatkan
sebagai bahan baku pupuk organik, karena kedua kompos yang dihasilkan dapat
memenuhi standar kualitas kompos menurut SNI 19 – 7030 – 2004.97 halamanSkripsi Sarjan
Analisa Unsur Hara Fosfor (P) pada Daun Kelapa Sawit Secara Spektrofotometri di Pusat Penelitian Kelapa Sawit (PPKS) Medan
No full textHave been conducted by analysis element of hara phosphorus (P) at palm leaf in Indonesian Oil Palm Research Institute at Medan. Determination of phosphorus rate
(P) in palm leaf conducted with method of Spektrofotometri UV-Visible. Result of analysis indicate that phosphorus rate the obtained is 0,139% - 0,150% in palm leaf. Of this result indicate that phosphorus rate in palm leaf still less, answer the demand of standard which have been determined by that is between 0,16%-0,19%.44 HalamanKertas Karya Diplom
Pemberian Amandemen untuk Meningkatkan Ketersediaan P dan Pertumbuhan Tanaman Jagung (Zea Mays L.) di Tanah
No full textThe pot research in the screen house examined the application of amendments (lime, humic acid, and biochar) to increase the availability of P nutrients and the growth of maize (Zea mays L.) in Ultisol soil. This study used a non-factorial randomized block design (RAK) with control treatment, lime CaCO3 at a dose of 1.5 x Aldd, humic acid at a dose of 400 ppm, 800 ppm, 1200 ppm, biochar of oil palm empty bunches with a dose of each. each 10 tons/ha, 15 tons/ha, 20 tons/ha, and has 3 blocks; and maize as indicator crops. Parameters observed were pH H2O, Al-dd, C-organic, P-available, P-soluble, P-Al, P-Fe, plant height, shoot dry weight, root dry weight and P uptake. The results showed that giving lime (1.5 x Al-dd) was good in overcoming the acidity of Ultisol soil as it was able to reduce Al-dd and increase soil pH, while the provision of humic acid (6.67g/pot) was better in supplying P nutrients, was able to increase P -available and P-easy to dissolve in the soil due to a decrease in the levels of P-Al and P-Fe in the soil. The application of biochar of oil palm empty fruit bunches (25 g/pot) tended to be better in increasing shoot dry weight,, root dry weight and P uptake of maize in Ultisol soil than lime and humic acid.69 HalamanSkripsi Sarjan
Analisis Tekstual dan Musikal Didong-Didong dalam Upacara Nambalken Gelar pada Masyarakat Karo di Desa Kuta Parit Kecamatan Selesai Kabupaten Langkat
No full textThis research discusses the textual and musical Didong-didong in the Nambalken Gelar ceremony in the Karo community. The aim of this research is to analyze the stages and forms of the Nambalken Gelar ceremony as well as the use and function of Didong-didong. The method used in this research is a descriptive qualitative research method. In this research, the author uses the theoretical approach to the basics of music analysis pioneered by William P. Malm. And using theory (Nettl, 1964: 68) which provides two approaches, namely: analyzing and describing what is heard and describing what is seen and writing it on paper in a certain way of writing. In analyzing the function of Didong-didong, the author applies the theory of 10 musical functions introduced by Alan P. Merriam. And to analyze the form of the ceremony, the author uses the theory of traditional ceremonies pioneered by Koentjaraningrat, which has several elements such as: the place where the ceremony takes place, the time the ceremony is held, the objects and equipment of the ceremony, and the people involved in the ceremony. The results of this research show that during the Nambalken Gelar ceremony there was a Didong-didong song sung by Perkolong-kolong. This song contains messages, hopes and prayers for the child whose name is written. The melody form in this song is the same but the verses are different. The conclusion obtained from this research is that Didong-didong is a song among the Karo people in Langkat which must be sung during the Nambalken Gelar ceremony in Langkat Regency.95 PagesSkripsi Sarjan
