ABSTRAK Air limpasan (runoff) pada area pertambangan terbuka umumnya memiliki tingkat kekeruhan yang tinggi dan/atau bersifat asam, sehingga memerlukan pengolahan sebelum memasuki badan air penerima. Pengolahan aktif merupakan metode yang efektif untuk diterapkan, dimana terdapat tahapan pengadukan cepat yang bertujuan salah satunya untuk pencampuran bahan kimia. Studi pustaka ini bertujuan melihat potensi pengaplikasian pengadukan hidrolis menggunakan baffled channel untuk meningkatkan efektivitas. Konfigurasi kolam harus terdiri dari dua bagian atau lebih agar proses dapat berjalan, kolam atenuasi di bagian hulu dan kolam hilir yang dapat berbentuk kolam labirin, meandering. Baffled channel dapat diposisikan pada saluran keluaran (outlet) dari kolam atenuasi. Sebuah pengadukan cepat akan berhasil ketika terpenuhinya gradien kecepatan pengadukan (G) dan waktu detensi (td) yang dipersyaratkan. Parameter yang dapat direkayasa untuk mencapai persyaratan tersebut adalah jumlah sekat (n) yang terdapat di sepanjang saluran. Kalkulasi jumlah sekat yang dibutuhkan harus dapat memenuhi parameter pengadukan pada setiap rentang debit minimum dan maksimum. Tercapainya kriteria pengadukan akan meningkatkan efektivitas tahapan pengolahan selanjutnya. Kata kunci : Pengadukan, baffled channel  ABSTRACT Runoff in open pit areas commonly contain high levels of turbidity and/or low level of pH, its requiring processing before entering the environment.

Level Of Understanding

AbstractThis aims of this research is to explore the Social Capital, the level of understanding of citizens about Disaster Mitigation in their area and readiness in dealing with it. This research is designed to apply qualitative strategies which are explorative, descriptive and explanative. Data collected by observation, literature study, interview or experiment. It is interesting to note that residents have often watched coverage of various disasters that occur in Indonesia through television, even understanding the great potential of disasters in their region. But based on their low level of Social Capital, it turns out they still lack adequate understanding of Disaster Mitigation in their region. Based on this data, it can be assumed that they only have a low level of preparedness in dealing with it, if a disaster does occur, they will become victims of such a large impact. Even in the event of a small-scale catastrophic event, it turns out that their understanding of Disaster Mitigation is still lacking, starting from the level of disasters, causes, anticipations, or even the consequences that will result. Therefore, a literature study is needed, strengthening a comprehensive understanding of Disaster Mitigation, raising critical awareness, and needing actions that directly involve citizens are urgently needed. The research output is designed in the form of national or international proceedings; national or international speaker certificate; with scale achievements following the stages: literature study, discovery of basic principles that have been formulated, experiments, towards a scientifically feasible model.   Penelitian ini bertujuan untuk mengeksplorasi Modal Sosial, tingkat pemahaman warga tentang Mitigasi Bencana di wilayahnya dan kesiapan dalam menghadapinya. Penelitian ini dirancang menerapkan strategi kualitatif yang berjenis eksploratif, deskriptif, dan eksplanatif. Data dikumpulkan dengan observasi, studi pustaka, wawancara atau eksperimen. Menarik untuk diteliti bahwa warga telah sering menonton liputan tentang berbagai bencana yang terjadi di Indonesia melalui tayangan televisi, bahkan memahami potensi besar bencana di wilayahnya. Namun dengan Modal Sosial yang dimilikinya, ternyata mereka masih kurang memiliki pemahaman yang memadai tentang Mitigasi Bencana di wilayahnya. Berdasarkan gambaran tersebut dapat diduga mereka hanya memiliki tingkat kesiapan yang rendah dalam menghadapinya, apabila bencana benar-benar terjadi, mereka akan menjadi korban terdampak yang begitu besar. Bahkan pada saat terjadi kejadian bencana yang berskala kecil sekalipun, ternyata masih kurang pemahaman mereka mengenai Mitigasi Bencana yang jelas mulai dari tataran perihal bencana, faktor penyebab, antisipasi, atau bahkan akibat yang akan ditimbulkannya. Oleh karena itu, diperlukan studi pustaka, penguatan pemahaman Mitigasi Bencana yang komprehensif, peningkatan kesadaran kritis, serta perlu langkah aksi yang langsung melibatkan warga sangat diperlukan. Luaran penelitian ini dirancangkan berupa publikasi prosiding nasional atau internasional; sertifikat pemakalah nasional atau internasional; dengan capaian skala mengikuti tahapan: studi pustaka, penemuan prinsip dasar yang telah diformulasikan, eksperimen, menuju model yang layak secara ilmiah.

Many results implicate perceptual processing in repetition priming, but little is known of potential mechanisms for priming. A new method was used to help determine the processing stage at which priming occurs. Priming pictures were presented under dominance or suppression generated by binocular rivalry. Although low-level, sensory attributes can be processed under rivalry suppression, there is no evidence that repetition priming can be supported by such low-level processing. Priming was found only for stimuli that were processed sufficiently to be identified in the priming stage. The results demonstrate that repetition priming requires processing of stimulus attributes into relatively high-level representations.

AbstractLow-level-jet (LLJ) periods are investigated by exploiting a long-term record of ground-based remote sensing Doppler wind lidar measurements supported by tower observations and surface flux measurements at the Jülich Observatory for Cloud Evolution (JOYCE), a midlatitude site in western Germany. LLJs were found 13% of the time during continuous observations over more than 4 yr. The climatological behavior of the LLJs shows a prevailing nighttime appearance of the jets, with a median height of 375 m and a median wind speed of 8.8 m s−1 at the jet nose. Significant turbulence below the jet nose only occurs for high bulk wind shear, which is an important parameter for describing the turbulent characteristics of the jets. The numerous LLJs (16% of all jets) in the range of wind-turbine rotor heights below 200 m demonstrate the importance of LLJs and the associated intermittent turbulence for wind-energy applications. Also, a decrease in surface fluxes and an accumulation of carbon dioxide are observed if LLJs are present. A comprehensive analysis of an LLJ case shows the influence of the surrounding topography, dominated by an open pit mine and a 200-m-high hill, on the wind observed at JOYCE. High-resolution large-eddy simulations that complement the observations show that the spatial distribution of the wind field exhibits variations connected with the orographic flow depending on the wind direction, causing high variability in the long-term measurements of the vertical velocity.

Study of vandalism level on softscape by park users at I Gusti Ngurah Made Agung Denpasar. This research was motivated by the existence of vandalism activities in I Gusti Ngurah Made Agung Park Denpasar as the result of human interactions between park user with their environment around this location as a public space. This study aims to identify level of vandalism and user perceptions of vandalism on softscape. The methods used in this research are survey method with collecting data techniques, observation, questionnaire distribution, and literature study. The result of this research showed that there are four variables that caused by vandalism on softscape in this area, such as scratching trees, nailing trees, littering around the plants and picking plants carelessly. The number of vandalism cases on softscape in this area reached about 13 cases that occurred with percentage 0.4% and western area or part of the field that is on Jalan Udayana is the area that received vandalism the most. Respondents in this study were visitors aged 12- 21 years old, which is the age of vandal on the park. The respondent’s perception of vandalism assumed that plants that are close or easy to reach by user and plants that have certain beauty or uniqueness are more vulnerable to be objects of vandalism. The low level of vandalism at I Gusti Ngurah Made Agung is still able to give users a sense of fun.

The Impact

Numerous methods of RNA-Seq data analysis have been developed, and there are more under active development. In this paper, our focus is on evaluating the impact of each processing stage; from pre-processing of sequencing reads to alignment/counting to count normalization to differential expression testing to downstream functional analysis, on the inferred functional pattern of biological response. We assess the impact of 6,912 combinations of technical and biological factors on the resulting signature of transcriptomic functional response. Given the absence of the ground truth, we use two complementary evaluation criteria: a) consistency of the functional patterns identified in two similar comparisons, namely effects of a naturally-toxic medium and a medium with artificially reconstituted toxicity, and b) consistency of results in RNA-Seq and microarray versions of the same study. Our results show that despite high variability at the low-level processing stage (read pre-processing, alignment and counting) and the differential expression calling stage, their impact on the inferred pattern of biological response was surprisingly low; they were instead overshadowed by the choice of the functional enrichment method. The latter have an impact comparable in magnitude to the impact of biological factors per se.

Complex Landscapes

Land cover classification (LCC) of complex landscapes is attractive to the remote sensing community but poses great challenges. In complex open pit mining and agricultural development landscapes (CMALs), the landscape-specific characteristics limit the accuracy of LCC. The combination of traditional feature engineering and machine learning algorithms (MLAs) is not sufficient for LCC in CMALs. Deep belief network (DBN) methods achieved success in some remote sensing applications because of their excellent unsupervised learning ability in feature extraction. The usability of DBN has not been investigated in terms of LCC of complex landscapes and integrating multimodal inputs. A novel multimodal and multi-model deep fusion strategy based on DBN was developed and tested for fine LCC (FLCC) of CMALs in a 109.4 km 2 area of Wuhan City, China. First, low-level and multimodal spectral–spatial and topographic features derived from ZiYuan-3 imagery were extracted and fused. The features were then input into a DBN for deep feature learning. The developed features were fed to random forest and support vector machine (SVM) algorithms for classification. Experiments were conducted that compared the deep features with the softmax function and low-level features with MLAs. Five groups of training, validation, and test sets were performed with some spatial auto-correlations. A spatially independent test set and generalized McNemar tests were also employed to assess the accuracy. The fused model of DBN-SVM achieved overall accuracies (OAs) of 94.74%± 0.35% and 81.14% in FLCC and LCC, respectively, which significantly outperformed almost all other models. From this model, only three of the twenty land covers achieved OAs below 90%. In general, the developed model can contribute to FLCC and LCC in CMALs, and more deep learning algorithm-based models should be investigated in future for the application of FLCC and LCC in complex landscapes.
