ANALISIS KUANTITAS DAN KUALITAS AIR BERSIH PELANGGAN PDAM KABUPATEN BOYOLALI DI KELURAHAN PENGGUNG
Full text linkARDI IRMANSYAH, 2010, “ANALISIS KUANTITAS DAN KUALITAS
AIR BERSIH PELANGGAN PDAM KABUPATEN BOYOLALI DI
KELURAHAN PENGGUNG”
Peranan air sangat penting bagi manusia, sehingga harus memenuhi standar
kuantitas dan kualitas air bersih. Penelitian ini menganalisis kuantitas air yang
dapat dipengarui oleh faktor teknis yaitu pemakaian meter air dan faktor ekonomi
yaitu tingkat kemampuan ekonomi masyarakat, ditunjukkan dengan rekening air
PDAM. Kebutuhan air pemukiman penduduk di Kelurahan Penggung
menggunakan air PDAM, maka kualitas air perlu diteliti.
Penelitian ini menggunakan metode deskriptif kuantitatif. Data yang diperlukan
antara lain data pembacaan meter air, rekening air PDAM, jumlah jiwa dalam satu
keluarga dan wawancara.
Hasil analisis menunjukkan bahwa pemakaian air rata-rata untuk kelompok
menengah ke atas sebesar 165,79 l/hr/jiwa, sedangkan rata-rata pemakaian air
untuk kelompok menengah kebawah sebesar 103,55 l/hr/jiwa. Kualitas air di
PDAM berdasarkan adanya chlor belum memadai, sedangkan berdasarkan warna
dan kekeruhan dalam keadaan baik.

No full textPRAYOGA BAGASKARA : Pertumbuhan dan produksi beberapa genotipe ubi jalar (ipomea batatas L.) terhadap perbedaan ketinggian tempat penanaman, dibimbing oleh Ibu Dr. NINI RAHMAWATI S.P, M.Si dan Bapak Dr. Ir. T. IRMANSYAH, MP.
Penelitian bertujuan untuk untuk mengetahui pertumbuhan dan produksi beberapa genotipe ubi jalar (Ipomoea batatas L.) terhadap perbedaan ketinggian tempat penanaman. Manfaat penelitian ini adalah untuk mengetahui karakteristik lingkungan, yang mendukung pertumbuhan dan produksi tanaman ubi jalar. Penelitian ini dilaksanakan di dua lokasi yang berbeda, lokasi satu (Berastagi) tepatnya di balai penelitian tanaman sayuran Tongkoh dengan ketinggian ± 1300 meter diatas permukaan laut dan lokasi dua (Medan) tepatnya di lahan percobaan Fakultas Pertanian USU dengan ketinggian ± 30 meter diatas permukaan laut. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Multi Lokasi dimana memiliki dua faktor yaitu genotipe lokal ubi jalar (dataran rendah, dataran tinggi) dan lokasi penanaman. Hasil penelitian menunjukan bahwa interaksi antara keduanya menunjukan pengaruh nyata antara genotipe dan lokasi penanaman. Ubi jalar mampu tumbuh dan berproduksi dengan baik selama tanah memiliki struktur yang memadai untuk umbi berkembang.PRAYOGA BAGASKARA: Growth and production of several genotypes of sweet potato (ipomea batatas L.) on differences in planting altitude, guided by Mrs. Dr.NINI RAHMAWATI S.P, M.Si and Mr. Dr. Ir. T. IRMANSYAH, MP
The aim of this study was to determine the growth and production of several genotypes of sweet potato (Ipomoea batatas L.) on the difference in planting height. The benefit of this research is to determine the environmental characteristics, which support the growth and production of sweet potato plants. This research was conducted in two different locations, location one (Berastagi) to be precise at the Tongkoh vegetable research center with an altitude of ± 1300 meters above sea level and location two (Medan) to be precise in the USU Faculty of Agriculture experimental field with an altitude of ± 30 meters above sea level. . This study using Randomized Block Design (RBD) multi locations with 2 factors, namely the local genotype of lowland sweet potato, upland and planting location. The results showed that the interaction between the two showed a significant effect between genotype and planting location. Sweet potatoes can grow and produce well as long as the soil has adequate structure for the tubers to develop.68 HalamanSkripsi Sarjan

(Brassica oleraceae var. acephala) on biological fertilizer application in some
plant spacing, supervised by : T. IRMANSYAH and JONATAN GINTING.
This research was conducted to determine the effect of bio-fertilizer and plant
spacing on the growth and production of kailan and interaction of both factors.
The research was carried out in the BPTB Tongkoh with an altitude of 1200
meters above sea level from March to May 2014. The design used randomized
block design with two factors, treatment of H0 biological fertilizer (control); H1
(5 ml / l); H2 (10 ml / l); H3 (15ml / l) and the spacing of J1 (20 x 25 cm); J2 (20
x 30 cm); J3 (20 x 35 cm) with the following combinations: J1H0, J1H1, J1H2, J1H3,
J2H0, J2H1, J2H2, J2H3, J3H0, J3H1, J3H2, J3H3. Parameter observed plant height,
number of leaves, canopy wet weight, weight wet roots, canopy dry weight, root
dry weight and fresh weight per plot sale. The results showed that bio-fertilizer
treatments significantly affected to the parameters of plant height 20-40 DAT and
number of leaves DAT 10 to 15 DAT, plant spacing affected to the parameter of
root fresh weight, root dry weight, and selling fresh weight per plot. While
significant interaction of both factors affected to plant height 5 to 15 DAT, leaf
number 5 DAT, and root fresh weight.77 HalamanSkripsi Sarjan

Assessment of Biomass Cover Crops in Oil Palm (Elaeis gueneensis Jacq.) Plantations in Peatlands and its Relationship with Soil Characteristics
No full textMUNAWARAH. Assessment of Biomass Cover Crops in Oil Palm (Elaeis gueneensis Jacq.) Plantations in Peatlands and its Relationship with Soil Characteristics (under the guidance of ABDUL RAUF as Chairman of the Supervisory Committee and T. IRMANSYAH as Member of the Supervisory Committee).
The clearing of peatlands for oil palm cultivation causes a decrease in soil surface due to the drying process. The presence of ground cover is able to rehabilitate the peat soil so that it supports the growth of oil palm (Elaeis guineensis Jacq.) by returning in the form of biomass. This study aims to evaluate the total biomass of vegetation on peatlands, the total biomass of vegetation on moisture, and the total biomass of vegetation on peat chemical characteristics. This research was conducted at PTPN IV Kebun Meranti Paham using the ex post facto method. Observations were made on 6 different years of oil palm planting. The results showed that there were differences in the total biomass of ground cover vegetation at each age of oil palm planting. The highest biomass in the 2011 planting year was 32,17 tons/ha and the lowest in the 2015 planting year was 13,46 tons/ha. The increase in total biomass can maintain soil moisture in the upper and lower layers of peat in young plants and increase C-organic and N-total content in the upper layer and increase pH, P2O5, and K2O in the lower layer of peat.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

sorghum (Sorghum bicolor (L.) Moench) with spacing and weeding time.
Supervised by EDISON PURBA and T. IRMANSYAH.
The aim of this research was to observe the response growth and result
sorghum (Sorghum bicolor (L.) Moench) with spacing and weeding time. This
research was conducted at Jl. Tri Darma Fakultas Pertanian Universitas
Sumatera Utara, Medanwith altitude 25meter above sea level with 2 factor
namely spacing (70x30, 70x20, 70x10) and weeding time (without weeding, 2
weeks after planting, 4 weeks after planting, 6 weeks after planting, 8 weeks after
planting, clean weeding).
Observed paramaters were plant height, number of leaves, diameter of
stem, days of flowering, wet weight of tassel per sample, wet weight of tessel per
plot, sample seed production, plot seed production, weight of 1000 seed. This
research showed the treatment of spacing had a significant effect against height of
plant at 6 and 8 week after plant and wet weight of tassel per sample.Weeding
time had a significant effect against plant height 6 and 8 after planting, number of
leaves 4 6 and 8 after planting, diameter of stem 4, 5, 6, 7 and 8 weeks after
planting, days of flowering, wet weight of tassel per sample, wet weight of tessel
per plot, sample seed production, plot seed production, weight of 1000 seed.77 HalamanSkripsi Sarjan
