Abstrak. Tulang punggung sebagai bagian dari tulang belakang yang mempunyai peran penting pada tubuh manusia. Trauma yang terjadi pada tulang punggung dapat mempengaruhi kemampuan sumsum tulang belakang untuk mengirim dan menerima pesan dari otak ke sistem tubuh yang mengendalikan sensorik dan motorik. Disk Hernia dan Spondylolisthesis merupakan contoh dari penyakit yang terjadi pada tulang punggung. Penelitian tentang klasifikasi penyakit atau kerusakan tulang dan sendi dari sistem kerangka masih jarang dilakukan. Padahal sistem klasifikasi tersebut dapat digunakan sebagai second opinion oleh para ahli radiologi sehingga dapat meningkatkan produktivitas dan konsistensi diagnosis dari ahli radiologi. Penelitian ini menggunakan dataset vertebral column yang memiliki tiga kelas (Disk Hernia, Spondylolisthesis, Normal) dan 310 instance yang terdapat pada UCI Machine Learning. Dalam penelitian ini menggunakan metode penerapan algoritma K-NN untuk klasifikasi penyakit Disk Hernia dan Spondylolisthesis pada tulang belakang. Data disusun dalam dua tugas klasifikasi yang berbeda namun terkait, yaitu kategori "normal" dan "abnormal". Algoritma K-NN melakukan pendekatan klasifikasi data dengan cara mengoptimalkan data contoh yang dapat dijadikan acuan sebagai data training untuk menghasilkan klasifikasi data tulang belakang berdasarkan proses belajar (learning). Hasil penelitian menunjukkan bahwa akurasi dari classifier K-NN sebesar 83%. Rata-rata lama waktu yang dibutuhkan untuk melakukan klasifikasi classifier K-NN 0,000212303 detik.Abstract. Vertebral column as a part of backbone has important role in human body. Trauma in vertebral column can affect spinal cord capability to send and receive messages from brain to the body system that controls sensory and motoric movement. Disk hernia and spondylolisthesis are examples of pathologies on the vertebral column. Research about pathology or damage bones and joints of skeletal system classification is rare whereas the classification system can be used by radiologists as a second opinion so that can improve productivity and diagnosis consistency of the radiologists. This research used dataset Vertebral Column that has three classes (Disk Hernia, Spondylolisthesis and Normal) and instances in UCI Machine Learning. This research applied the K-NN algorithm for classification of disk hernia and spondylolisthesis in vertebral column. The data were then classified into two different but related classification tasks: "normal" and "abnormal". K-NN algorithm adopts the approach of data classification by optimizing sample data that can be used as a reference for training data to produce vertebral column data classification based on the learning process. The results showed that the accuracy of K-NN classifier was 83%. The average length of time needed to classify the K-NN classifier was 0.000212303 seconds.

In general, hospitals in Indonesia treat wastewater using a biological method, namely an aerobic anaerobic biofilter system. The anaerobic aerobic biofilter Waste Water Treatment Plant (WWTP) system in the hospital consists of a screen tub, fat catcher tank, initial settling tank, aerobic biofilter pond, aerobic biofilter and final settling tank, chlorination tank and indicator pond. So that this wastewater treatment method has the disadvantage of requiring an expensive investment, because it requires a large area of land, uses biofilters, pumps, blowers and chemicals in its operation. Alternative methods for treating hospital wastewater can use a microfiltration membrane, where the results of the study show that the removal of oily wastewater reaches 82.5%, BOD 90%, COD 85% and total Coli up to 70%. In addition, it can remove particles from wastewater measuring 0.04 to 100 microns. The problem faced in the use of microfiltration membranes is the rapid occurrence of fouling/saturation on the surface of the microfiltration membrane causing the operation time of wastewater treatment not to be in a long time. The duration of this treatment causes the problem of a small amount of wastewater being treated and other problems, membrane replacement is faster. The purpose of the research is to determine the performance of the preliminary treatment for microfiltration membranes made from alum, silica sand and activated carbon for parameters ph, bod, cod, tss, ammonia, oil and fat, total coliform wastewater. Analyzing the effect of differences in pre-processing materials for microfiltration membranes made from alum, silica sand and activated carbon on the quality parameters of ph, bod, cod, tss, ammonia, oil and fat, total coliform. The research method carried out is a quasi-experimental, namely research that aims to explain things that will happen to the research variables through manipulation and control of variables with a design using pre test (before treatment) and post test (after treatment) to the object under study. The results of the study are as follows: 1) the average quality of hospital wastewater is temperature 28.8 °C, pH 7, BOD 79 mg/l, COD 167.05 mg/l, Total Suspended Solid 68 mg/l, Ammonia 4 mg/l, Phosphate 0.745 mg/l, Fatty Oil 1.64 mg/l, coliform 2,200 mpn/100 ml. 2) Analysis of the comparison of the most effective materials on the parameters, for BOD is silica sand 78.24%, COD is silica sand 56.25%, total suspended solid is 83.42% activated carbon, ammonia is silica sand 56.49%, phosphate is 80.43% activated carbon, fatty oil is 80.43% alum, coliform is a 40.91% microfiltration membrane.

“…The physician then proceeds to apply some pressure on the patients’ hip toward the table located in front of the physician, resulting in lumbar extension from the previously flexed state. Tenderness is evident when the interspinous spaces are palpated with a wider gap, appearing during the shift from flexing to extending [ 7 ]. However, it has been speculated that tightness or spasm in the paraspinal muscles secondary to pain when standing may have a splinting effect, thus reducing the apparent instability on flexion-extension radiographs.…”

Background Spondylolisthesis refers to anterior displacement of the vertebral body in reference to the bordering vertebral bodies, causing segmental instability, that mostly occurs in the middle lumbar spine and the lumbosacral junction. If surgery is indicated, open technique with lumbar pedicle strew instrumentation is the standard therapy. Recently, minimally-invasive technique can be applied in spondylolisthesis surgery using percutaneous long-arm pedicle screws with a promising short- and long-term outcome. Objective This paper reviews the development of minimally-invasive percutaneous long arm pedicle screws from techniques to reported outcomes. Conclusion Minimally-invasive surgery utilizing advance techniques and instrumentations can give a better outcome in spondylolisthesis surgery associated with lesser blood loss, pain level, and length of hospitalization.
