Aliran permukaan/limpasan (run off) merupakan salah satu variabel hidrologi yang sangat penting di dalam menunjang kegiatan pengembangan sumber daya air. Metode prediksi yang handal untuk menghitung jumlah dan laju limpasan yang berasal dari permukaan tanah dan bergerak menuju sungai di suatu DAS yang tidak dilengkapi alat ukur (ungaged watershed) adalah suatu pekerjaan yang sangat sulit dan memerlukanwaktu yang banyak. Penelitian ini dilakukan di DAS Ciliwung Hulu, yang merupakan daerah penting dalam kotribusi banjir di Jakarta. Untuk mengetahaui run off yang terjadi, digunakan data curah hujan dan debit Tahun 2007-2009. Sebagai model, untuk mengetahui run off menggunakan peta penggunaan lahan, peta jenis tanah, dan topografi. Peta-peta tersebut diolah dengan menggunakan Arcview, sehingga didapatkannilai CN. Berdasarkan analisis perhitungan, besarnya debit mendekati 50% dari tebal hujan. Kondisi ini mengindikasikan bahwa kondisi DAS Ciliwung Hulu sudah tidak mampu lagi menyerap curah hujan dengan baik. Korelasi antara hasil prediksi run off model yang menggunakan CN dengan perhitungan run off observasi cukup baik. Hal ini menunjukkan bahwa metode Curve Number cukup dapat mepresentaskan hubungancurah hujan dengan aliran permukaan (run off). kata kunci : Run off observasi, run off model, curve number AbstractRun off (surface flow) is one of the most important hydrological variable in supporting the activities of water resources development. A reliable prediction method to calculate the amount and rate of runoff from the land surface caused by the rain that falls in a watershed that is not equipped with measuring devices (un gauge watershed) is a verydifficult job and requires a lot of time. The research was conducted in the watershed Ciliwung Hulu, which is an important area in relation to the incidence of flooding in Jakarta. Curve Number (CN) method can be used to predict the amount of runoff from a watershed. This model required input of rainfall; land cover maps; soil type maps,and topography. The maps are processed using Arc View software, so we get the value of CN. In this study, we used of rainfall and discharge data 2007-2009. Based on the analysis of calculation, known that amount of surface flow approaching 50% of rainfall depth. This condition indicates that the Ciliwung Hulu watershed conditions were not ableand proper to absorb of rainfall. The correlation between the results of run-off prediction models using CN with run-off observation was quite good. This indicated that the Curve Number method could be able to represent the relationship of rainfall with surface flow (run off) and also to predict runoff key words: Run off observation, run-off model, curve number

Sistem komposting windrow adalah metode yang umum digunakan untuk pengolahan limbah padat oraganik. Temperatur adalah variabel yang penting dalam pemodelan yang mana dapat disimulasikan dengan memperkirakan perubahan keseimbangan panas dari komponen pada setiap saat. Energi panas biologis adalah istilah yang paling signifikan dalam keseimbangan panas. Dalam tulisan ini pembangkitan panas oleh proses komposting diuji dan dievaluasi dalam penerapannya untuk sistem windrow skala penuh. Sampai saat ini keakuratan memprediksi laju degradasi substrat telah menjadi tantangan utama. Penggunaan pendekatan induktif berdasarkan ekspresi kinetik orde pertama ataupun relasi kinetik empiris telah ditemukan untuk tujuan praktis. Bagaimanapunjuga faktor skala koreksi untuk proses dan tipe substrat tertentu mungkin dibutuhkan investigasi lebih lanjut untuk perbedaan sempit diantara skala lab dan skala sistem skala penuh. Kata kunci: Komposting terbuka, keseimbangan panas, panas biologis, model pengkomposan AbstractWindrow composting is the most common method for organic solid waste treatment. Temperature is an important state variable in modelling, which could be simulated by estimating the change of heat balance components at any moment. Biological heat energy is the most significant term in the heat balance. In this paper biological heat generation of the composting process are examined and their applicability for a full-scale windrow system is evaluated. It is found that, to date, the accuracy of predicting the rate of substrate degradation has been a major challenge. The use of an inductive approach based on either first-order kinetic expression or empirical kinetics relation was found to be more feasible for practical purposes. However a scale-up correction factor for particular processes and types of substrate may need to be further investigated to narrow the discrepancies of kinetic performances between laboratory and full-scale systems.

Published: January 2019

Waste as one of human activity products should be managed in order to minimize its negative impacts to the environment and human health. Environmental pollution will also take place due to waste which contains hazardous substances, such as used battery, accu and broken TL bulbs. Production of those goods uses plublum (Pb) in its process, so that the Pb will be carried later by the leachate flow to the environment. This work was an experiment with pre and post tests design which also used reference group as a control towards Pb parameter. Statistical analyzes was carried out using Anova and T tests with the degree of confidence of 95%. Result of the anova test of reference group with a variation of detention time was probability of about 0.293, whereas the experimental group resulted a probability of 0.005. The T-test for both reference and experimental groups with a variation of detention timegave different values of Pb parameter where the different with the probability of 0.000. The result showed that concentration of Pb in leachate decreased after it was treated using alum and lime. the significant reduction is at leaving time of 3 hours, i.e. 798.3 mg/L (75.7%). Therefore, it ca be concluded that treatment using alum and lime can be applied to reduce concentration of Pb in a lechate.
Survival of Overwintering Aedes albopictus Eggs Under Natural Conditions In North-Central Florida
Authors: Jiang Yongxing 
Published: January 2019

ABSTRACT
Aedes albopictus mosquitoes overwinter as eggs in north-central Florida. Knowledge of this species' overwintering survival rate is of great interest to local mosquito control districts. In this study, field-collected Ae. albopictus eggs were exposed to natural conditions during winter 2016–17 in Gainesville, FL, to determine the overwintering survival rate. Individual strips of germination paper containing eggs of this species were collected from ovitraps in November 2016 then later clipped to the inner edge of empty flowerpots and placed in the Department of Public Works compound, City of Gainesville, in December. Egg strips that remained outdoors were later brought back to the laboratory and hatched in late March 2017. Significant differences were found among the 5 ambient environmental exposure methods (configurations) in terms of egg survival rate, egg collapsed rate, and egg unaccounted rate, whereas no significant difference was observed on the egg intact rate. Egg strips stored in flowerpots with the drainage hole sealed had the highest survival rate (18.3%), whereas eggs stored in an open covered area had the least survival rate (2.4%). The effect of different storage conditions on the survivorship of overwintering Ae. albopictus eggs in north-central Florida is discussed.

Published: January 2019

ABSTRACTAedes aegypti is the primary vector for serious diseases, including those caused by chikungunya, dengue, and Zika viruses. In 2017, the Southern Nevada Health District first detected this invasive species in Clark County, NV, including in the city of Las Vegas. We analyzed Ae. aegypti from the city of North Las Vegas to determine the likely source of the invasion. We genotyped a sample of Ae. aegypti at 12 highly variable microsatellites and analyzed the data in reference to published data from 25 sites in the southern USA. We found that the Ae. aegypti in Las Vegas most likely invaded from southern California. Knowing the source of new invasions may provide information about the invading population (e.g., previous insecticide exposure) and can help prevent future invasions from the region.

ABSTRACTDetoxifying pathways of mosquitoes against the neem (Azadirachta indica) extracts are still unclear. The aim of the present study was to investigate the role of adenosine triphosphate–binding cassette (ABC) transporters in this process in Anopheles stephensi, one of the main malaria vectors in southern Asia. Third-stage larvae of An. stephensi were fed with fish food alone or in combination with neem extract at 0.5%, 1%, 5%, and 10%. Six ABC-transporter genes from 3 different subfamilies (B, C, and G) were analyzed to assess their relative expression compared with controls. A bioassay was also performed to assess larval mortality rate at different concentrations and in combination with verapamil, an ABC-transporter inhibitor. No significant variation in the expression levels of any transporter belonging to the B, C, and G subfamilies was detected. Furthermore, the use of verapamil did not induce an increase in mortality at any of the tested neem extract concentrations, indicating that ABC transporters are not involved in the detoxification of neem extracts in An. stephensi larvae.

Objective: To demonstrate the patterns of syndesmosis reconstruction in ankle fractures via the measurement of pre-established and universally accepted parameters. Methods: In a retrospective study, fractures with radiographic images obtained during the postoperative period showing fixation of the distal tibiofibular syndesmosis were selected. After this selection, fracture reduction and syndesmosis fixation were evaluated by measuring radiographic parameters in the selected cases. Results: Twenty-three patients (63.8%) were male. Fourteen fractures (38.8%) were operated on by a senior surgeon (foot and ankle specialist). All syndesmoses were fixed with only 1 screw, and 35 patients (97.2%) had syndesmosis fixation involving 3 cortices. The mean syndesmosis fixation height from the articular surface was 2.20cm. Four fractures (11.1%) presented radiographic signs of medial ligament reconstruction. Regarding measurement of the tibiofibular space, in the anteroposterior (AP) view, 33 patients (91.6%) had values within the normal range. Regarding the tibiofibular overlap, in the AP view, 19 patients (52.7%) had measurements with values greater than 10mm (normal). In the evaluation of tibiofibular overlap, in the true AP view, all patients (100%) presented measurements greater than 1mm (normal). Regarding the measurement of the talocrural angle, only 1 patient did not have normal parameters. Regarding the medial clear space, only 2 patients (5.5%) had values above normal during the postoperative period. Conclusion: The adoption of objective parameters, in a standardized manner and relative to the contralateral side, adds additional value to the evaluation and ensures an accessible and reproducible method for the evaluation of these injuries.

Published: January 2019

Objective: The objective of this study was to evaluate the efficacy of the systematic protocol developed in our institution for the treatment of Charcot arthropathy (CA) of the midfoot, specifically for cases anatomically classified as Brodsky type II. Methods: Sixty patients with type II CA were treated in the period between 1997 and 2017 following a systematic protocol adopted at our institution. Two patients (3%) were lost to follow-up, leaving a total of 58 patients with 64 feet (six had bilateral involvement). The mean follow-up time was 31 months (range 12 to 150), and the mean age was 55 years (range 27 to 73). Conservative treatment was indicated in 41/64 of the extremities (64%), and surgical treatment was indicated in 23/64 of the extremities (36%). We considered the result as satisfactory when the patient was able to walk independently, placing full body weight on the foot. The result was considered unsatisfactory when the affected extremity presented clear instability and was deformed to the point that it was not possible to fit it in a stabilizing orthosis or for the patient to place their weight on the foot during walking as well as when it was necessary to perform an amputation. Results: We obtained a satisfactory outcome in 54/60 patients (90%) and in 58/64 feet (91%). In 19/23 of the operated feet (83%) and 39/41 of the conservatively treated feet (95%), the result was atisfactory. Conclusion: The systematic treatment protocol developed at our institution allows achievement of a favorable prognosis regarding the clinicalfunctional outcome of type II CA, with conservative treatment being sufficient in most cases.
