Development of Pratylenchus Coffeae in Biochar Applied Soil, Coffee Roots and Its Effect on Plant Growth
Biochar improve physical, chemical and biological properties of soil. It may also be used as botanical pesticides. The experiment was aimed to determine the effect of biochar on population development of parasitic nematode Pratylenchus coffeae. The experiment was carried out in Nematology Laboratory and in a greenhouse of Indonesian Coffee and Cocoa Research Institute (ICCRI), Jember, Indonesia. The experiment was arranged according to completely randomized design with six treatments of biochar concentrations, i.e. 4%; 3%; 2%; 1%; 0.5% and 0% dry weight of soil. Research results revealed that biochar application of 4.0% was effectively killed 74.5% of P. coffeae, while the lowest mortality level of 37.5% at biochar 0.5% treatment. In the greenhouse trial, application of biochar 4.0% was the most effective in suppressing the population of parasitic nematode in coffee seedlings. Application of biochar was also able to increase the growth and biomass of coffee seedlings
Kajian Dampak Keberadaan Industri PT. Korindo Ariabima Sari di Kelurahan Mendawai, Kabupaten Kotawaringin Barat
Kota Pangkalan Bun sebagai Ibukota Kabupaten Kotawaringin Barat mengalami perkembangan cukup pesat. Salah satu faktor yang mampu mempengaruhi perkembangan wilayah tersebut adalah industri PT. Korindo Ariabima Sari di Kelurahan Mendawai. Selain itu, keberadaan industri tersebut telah memberikan dampak terhadap kondisi fisik, lingkungan, dan sosial ekonomi. Tujuan penelitian ini adalah mengkaji dampak keberadaan industri PT. Korindo Ariabima Sari, baik dampak positif dan negatif berdasarkan kondisi fisik, lingkungan, dan sosial ekonomi. Penelitian ini menggunakan pendekatan kuantitatif dengan metode kuantitatif serta teknik analisis deskriptif dan spasial. Berdasarkan hasil analisis, menunjukkan bahwa industri PT. Korindo Ariabima Sari cenderung memberikan dampak negatif terhadap kondisi fisik (penggunaan lahan) dan lingkungan. Luas Perubahan penggunaan lahan di Kelurahan Mendawai sejak Tahun 1979-2012 sekitar 163,038 Ha dengan Perubahan terbesar terjadi pada hutan seluas 59,318 Ha menjadi permukiman (17,847 Ha) dan industri (16,271 Ha). Selain itu, dampak negatif terhadap kondisi lingkungan ditunjukkan dengan terjadinya degradasi lingkungan ditinjau berdasarkan kebisingan, pencemaran udara, dan pencemaran air. Selain dampak negatif, industri tersebut juga memberikan dampak positif terhadap kondisi fisik (ketersediaan fasilitas umum dan kondisi prasarana jalan) dan sosial ekonomi. Hal ini dapat dilihat dari ketersediaan fasilitas umum dan kondisi prasarana jalan cukup lengkap dan memadai, sedangkan tingkat pendapatan masyarakat saat ini diatas UMR Kota Pangkalan Bun sebesar Rp. 1.600.000,-. Rekomendasi dari penelitian ini adalah perlunya zonning regulation untuk mengendalikan perkembangan kawasan permukiman dan dampak lingkungan
Pengetahuan Ibu Primipara Tentang Faktor-faktor Yang Dapat Mempengaruhi Produksi Asi
Infant mortality in Indonesia is still high. That is due to serious disease problems. One way to anticipate serious disease's attack that is increasing the body's immune baby with breast-feeding infants. Obstruction of breastmilk production in primiparous mother become one of problem in Tugurejo Hospital. The purpose of this study to assess knowledge of primiparous mothers about factors that may affect milk production. Type of this research was quantitative research, which was a descriptive survey. The method used of this research was cross sectional. Population of this research is all of primiparous mother in Room Bougenville Tugurejo Hospital Semarang. The research used total sampling with 60 respondents. The result of this study showed that knowledge of primiparous mothers was good and enough, but there were primiparous mother that had less and not good knowledge in factor nutrition, rest and sleep, oxytocin message, used of contraceptive, and breastfeeding technique. That's why, primiparous mother need to increase more information about the way can product breastmil
Uji Fitokimia dan Antioksidan Ekstrak Etanol Buah Terung Asam (Solanum Ferox L)
Penelitian ini bertujuan untuk mengetahui kandungan senyawa kimia dan aktivitas antioksidan ekstrak etanol buah terung asam (Solanum ferox L). Untuk mencapai tujuan tersebut digunakan beberapa cara yaitu dengan melakukan uji fitokimia alkaloid, terpenoid, steroid, saponin, fenolat secara umum, dan flavonoid. Hasil dari uji fitokimia menunjukkan reaksi positif terhadap beberapa pereaksi yaitu uji alkaloid, uji terpenoid, uji fenolat dan uji flavonoid. Sedangkan uji steroid dan saponin tidak memberikan hasil yang positif terhadap pereaksi. Selanjutnya dilakukan uji antioksidan dan diperoleh nilai IC50 sebesar 177,16 ppm. Sehingga dapat disimpulkan ekstrak etanol buah terung asam memiliki aktivitas antioksidan sedang
Peripherally Inserted Central Catheterdan Pemberian Terapi Intravena Pada Neonatus
Previous studies have found that peripherally inserted central catheter (PICC) is effective for delivering an intravenous therapy. However, few studies were found to compare the effectiveness of PICC with peripheral intravenous access. The purpose of this study was to compare the effectiveness of intravenous therapy using peripheral intravenous access and PICC in hospitalized neonates. This study was a descriptive comparative. By using a purposive sampling technique, 32 neonates were involved as subjects of peripheral IV access group (n=16) and PICC group (n=16). Data were collected using observation forms for 24 hours within 5 days in a row. A Fisher Exact test was utilized to analyze the data. The results indicated that PICC was more effective than peripheral intravenous access (ρ=0.00) in providing intravenous therapy for neonates. Accordingly, PICC is recommended for neonates requiring intravenous therapy in the hospital
Eksperimentasi Model Problem Based Learning Dan Discovery Learning Pada Materi Perbandingan Dan Skala Ditinjau Dari Sikap Peserta Terhadap Matematika Didik Kelas VII SMP Kabupaten Klaten Tahun Pelajaran 2013/2014
Abstrack: The aims of this research were to determine: (1) the better students' achievement in learning by using Problem Based Learning (PBL), Discovery Learning (DL) or direct learning models (2) the better students' achievement among the students who have positive, neutral or negative attitude (3) the better students' achievement in each category attitude, in learning by using PBL, DL or direct learning models (4) the better students' achievement in each learning model, among the students who have positive, neutral or negative attitude. This research used a quasi-experimental research with the population of seventh grade students of Junior High Schools in Klaten Regency which have implemented curriculum 2013 in the Academic Year 2013/2014. The sampling technique used stratified cluster random sampling and three schools selected namely SMPN 1 Delanggu, SMPN 1 Prambanan and SMPN 2 Wedi. Two-way variance analysis was used to test the hypothesis, followed by scheffe' technique. Considering the result of analysis, the following conclusion could be drawn. (1) The students' achievement who learnt by using DL was better than PBL and direct learning models. The students' achievement who learnt by using PBL were similar to direct learning models. (2) The students' achievement with positive attitude was better than neutral and negative attitude. The students' achievement with neutral attitude was better than negative attitude. (3) In the positive and neutral attitude, the students' achievement who learnt by using PBL, DL and direct learning models were similar. In the negative attitude, the students' achievement who learnt by using DL model were better than PBL and direct learning models and the students' achievement who learnt by using PBL and direct models were similar. (4) In learning by using PBL, the students' achievement with positive attitude were better than negative one, the positive and neutral attitude ware similar and the neutral and negative attitude were similar too. In learning by using DL, the student's achievement with positive, neutral and negative attitude were similar. In learning by using direct learning, the students' achievement with positive attitude were better than the negative one, the positive and neutral attitude were similar and the neutral and negative attitude were similar too
