Kajian Pemberian Zat Pengatur Tumbuh Terhadap Pertumbuhan Stek Tanaman Buah Naga (Hylocereus Costaricensis)

Tanaman buah naga ( Hylocereus costaricensis) merupakan salah satu tanaman yang berasal dari family Cactaceae yang tergolong baru di masyarakat Indonesia. Kebutuhan buah naga di Indonesia cukup besar, namun kebutuhan tersebut belum mampu dipenuhi oleh produsen. Tujuan penelitian ini adalah untuk mengetahui adanya interaksi antar kombinasi perlakuan yang tepat dalam perbanyakan tanaman buah naga. Penelitian ini dilaksanakan pada bulan Mei sampai Juli 2014 dalam green house STPP Malang dengan menggunakan Rancangan Acak Kelompok Faktorial (RAKF) dengan faktor 1: bahan stek yaitu B1 batang ujung dan B2 batang bawah dan faktor 2: konsentrasi ZPT sebagai perlakuan(1 kontrol dan 6 perlakuan) dan 3 ulangan, yaitu : N0 : Kontrol (Tanpa ZPT), N1 : 25 mg/10 ml, N2 : 50 mg/10 ml, N3 : 75 mg/10 ml, N4 : 100 mg/10 ml, N5 : 125 mg/10 ml, dan N6 : 150 mg/10 ml. Pengamatan yang dilakukan secara distruktif dan non distruktif. Hasil penelitian menunjukkan adanya interaksi nyata pada kombinasi perlakuan bahan stek dengan konsentrasi ZPT terhadap pertumbuhan buah naga pada parameter pengamatan saat muncul tunas (hst), persentase tanaman berakar, Jumlah tunas dan panjang tunas, Sedangkan untuk parameter pengamatan persentase tanaman hidup (%), persentase tanaman berakar, jumlah akar, persentase tanaman bertunas, serta bobot basah, menunjukan hasil yang tidak berbeda nyata terhadap perlakuan kombinasi bahan stek dan konsentrasi ZPT.

Rancang Bangun dan Implementasi Automatic Transfer Switch (Ats) Menggunakan Arduino Uno dan Relai

Sistem cadangan/backup catudaya mutlak diperlukan pada perangkat elektronika yang memerlukan energi listrik yang tidak terhenti. Cadangan catudaya digunakan untuk menggantikan sumber utama PLN. Pada penerapannya diperlukan sebuah perangkat pendukung berupa Automatic Transfer switch (ATS) untuk melakukan pensaklaran dari sumber utama ke cadangan catu daya atau sebaliknya. Pada paper ini, dibahas realisasi perangkat ATS berbasis mikrokontroler yang bekerja berdasarkan pembacaan arus dan tegangan. Sistem ini juga dilengkapi dengan komunikasi berbasis LAN untuk mengirim data monitoring. Setelah dilakukan pengujian, perangkat ATS dapat mengukur arus dan tegangan dengan rata-rata kesalahan 3,76% dan 0,21% pada pengukuran generator set dan sumber PLN. Pengujian lainnya, sistem relai dapat berfungsi untuk memindahkan sumber listrik dari sumber utama ke sumber cadangan atau sebaliknya

Maternal and neonatal complications of fetal macrosomia: cohort study

Objective: To estimate risks of maternal and neonatal complications in pregnancies with macrosomia. Method: This was a retrospective cohort study undertaken at a large maternity unit in United Kingdom between January 2009-December 2016. We compared the incidence of complications in pregnancies with macrosomia, defined by birthweight (BW)>4,000 g and severe macrosomia with BW>4,500 g, to those in pregnancies with normal BW 2,500-4,000 g. Regression analysis was undertaken to determine odds ratios (OR) [95% confidence interval (CI)] for pregnancy complications in macrosomic compared to normal BW group. Results: The study population of 35,548 pregnancies included 4,522 (12.7%) with macrosomia, 643 (1.8%) with severe macrosomia and 31,026 (87.3%) with normal BW. In macrosomia group, adjusted OR was 3.07 (95%CI:1.64,2.01) for cesarean section for failure to progress, 2.40 (95%CI:1.95,2.96) for post-partum haemorrhage, 2.29 (95%CI:1.86,2.82) for sphincter injury, 10.37 (95%CI:8.57,12.55) for shoulder dystocia, 28.48 (95%CI:8.94,90.67) for brachial plexus injury, 32.33 (95%CI:3.76,278.15) for birth fractures and 4.40 (95%CI:2.20,8.82) for hypoxic-ischemic encephalopathy. The respective values for severe macrosomia were 4.32 (95%CI:3.05,6.13), 2.93 (95%CI:1.93,4.44), 3.12 (95%CI:1.92,5.08), 28.74 (95%CI:20.75,39.79), 73.92 (95%CI:15.05,363.16), 87.17 (95%CI:7.72,984.96) and 13.77 (95%CI: 5.16,36.75). Conclusion: Macrosomia is associated with serious adverse perinatal outcomes. This study provides accurate estimates of risks to aid in pregnancy management

Hydrogen Energy Storage: New Techno-Economic Emergence Solution Analysis

International audienceThe integration of various renewable energy sources as well as the liberalization of electricity markets are established facts in modern electrical power systems. The increased share of renewable sources within power systems intensifies the supply variability and intermittency. Therefore, energy storage is deemed as one of the solutions for stabilizing the supply of electricity to maintain generation-demand balance and to guarantee uninterrupted supply of energy to users. In the context of sustainable development and energy resources depletion, the question of the growth of renewable energy electricity production is highly linked to the ability to propose new and adapted energy storage solutions. The purpose of this multidisciplinary paper is to highlight the new hydrogen production and storage technology, its efficiency and the impact of the policy context on its development. A comprehensive techno/socio/economic study of long term hydrogen based storage systems in electrical networks is addressed. The European policy concerning the different energy storage systems and hydrogen production is explicitly discussed. The state of the art of the techno-economic features of the hydrogen production and storage is introduced. Using Matlab-Simulink for a power system of rated 70 kW generator, the excess produced hydrogen during high generation periods or low demand can be sold either directly to the grid owners or as filled hydrogen bottles. The affordable use of Hydrogen-based technologies for long term electricity storage is verified

Design and Study of a Nanocavity-based One-dimensional Photonic Crystal for Potential Applications in Refractive Index Sensing

Refractive index (RI) can be used to identify a particular substance and determine its purity and concentration. The RI of glucose solution with various concentrations can be determined using a distributed Bragg reflective (DBR) device containing a nanocavity. The optical property of the reflection spectrum produced by DBR is sensitive to the variation of the refractive index. In this study, a DBR with a cavity width of 220 nm, located in the middle of the device, is designed and used to sense the variation in the refractive index of glucose at different concentrations. The proposed design showed a sharp dip pattern within the reflection spectrum. The wavelength of the absorption peak was found to be sensitive to trivial variations in the refractive index of glucose solution. Results showed that the variation in the refractive index of glucose within the order of Δn = 0.02 has led to a noticeable shift in the absorption spectrum by Δλ = 2.6 nm. Furthermore, the sensitivity of the proposed device was found to be 130 nm/RIU which is considered high compared with those reported in the literature. Hence, the proposed structure can be a promising optical device for chemical ultrasensing applications

To investigate the performance of some sunflower genotypes to phosphorus fertilizer rates and planting dates to germination characters and seedling parameters. A laboratory experiment accompanied in seed lab during April and May 2017.The experiments included six sowing dates at 1th May, 15th May and 31th May, three soybean cultivars namely Crawford, Giza 22 and Giza 111 and three rates of phosphorus fertilizer viz. 0, 37.2 and 74.4 kg P2O5/ha.The tallest shoot, great percentages of germination, the lowermostpercentagesof dead seedand the highestcoefficient of velocitypercentage from sown on mid-May. In addition, the lowest days of germination time was produced from sown on first May. Whereas, the tallest root, the highest weight of fresh shoot and root as well as shoot dry weight from sown on end-May.The results clearly revealed that the highest percentage of germination, soot length and root length obtained from sown cv. Giza 111. The uppermostenergy of germination, shoot and root dry weight were recorded from sown Giza 22 cultivar. In addition, sown Crawford cultivar produced the highestdead seedpercentage and the lowest mean germination time.The results indicated that the lowest mean germination time and maximum percentage of coefficient of velocity, tallest shoot and root, weight of fresh shoot, shoot and dry root were obtained fromfertilizationof phosphate at the rate of31 kgP2O5/fed. It summarized that seed Giza 111 cultivar recorded the best in seed viability when sown on first May and fertilized with phosphorus fertilizer at the rate of 74.4 kg P2O5/ha
