Jalur puntara jawa merupakan jalan raya wilayah utara jawa membentang dari merak sampai ke banyuwangi. Jalur pantura ini merupakan jalur padat yang dilalui oleh kendaraan baik roda 4 maupun lebih. Beban jalan pantura per tahun mencapai 1 juta ton. Selain itu juga dengan beban ini merupakan penyumbang penggunaan BBM (bahan bakar minyak) yang lebih sebesar 42 ribu kiloliter dan mengakibatkan pemberi emisi udara cukup banyak sebesar 350 ton per hari. Dengan demikian semakin banyak kendaraan yang melintas jalur pantura, sehingga perlu diketahui tentang jumlah kendaraan yang melintas dijalur pantura secara otomatis oleh sistem. Data ini dapat dijadikan rujukan beban jalan pantura secara tepat. Pada penelitian ini, menggunakan beberapa algoritma dari blob detection dengan menggunakan library openCV dan kalman filter. Hasil dari deteksi dengan menggunakan bolb deteksi masih terdapat beberapa error yang cukup besar dan menggunakan kalman filter didapatkan 78.81 %.
Ayat Toleransi Prespektif Ibnu Jarir Ath-Thobari

Ibnu Jarir Ath-Thabari he is one of the mufassir scholrs who handed dwon the verse of the Quran using the Bil Ma’stur method (interpreting the verse with periwayatan). He sendiai manpret the Al Baqarah verse 256 with the periwayatan path, both from the hadist and the mufassirin before, in lafadz “there is no complusion to (enter) Islam as someone is not forced to convert to Islam, the latters Alif and Lam actually entered lafadz to clarify the lafadz that Allah intended in his word there is no complusiaon to enter it, nemely Islam. And bloch Came in. Alif and Lam as a subtitute for the latter ha wich was hidden in the lafadz call, than the meaning the verse when Allah is haigh and great, there is no compulistion to enter His religion, in fact the ruth is clear from the wrong path. In my opinion, this opinion is more concred with verse revelation, in Lafadz uall the most apropriate opinio about the meaning in my opinion is, that every person who was adultery with Allah, then mean worshiping other than him, sometimes by forcing others for worship him, sometime people on the basis ofthe willingness of the those who worship themselves. The wor ship was also in the form of humans, ghost, statuse, idols, and others.

OBJECTIVEThe accuracy of stereoelectroencephalography (SEEG) electrode implantation is an important factor in maximizing its safety. The authors established a quality assurance (QA) process to aid advances in implantation accuracy.METHODSThe accuracy of three consecutive modifications of a frameless implantation technique was quantified in three cohorts comprising 22, 8, and 23 consecutive patients. The modifications of the technique aimed to increase accuracy of the bolt placement.RESULTSThe lateral shift of the axis of the implanted bolt at the level of the planned entry point was reduced from a mean of 3.0 ± 1.6 mm to 1.4 ± 0.8 mm. The lateral shift of the axis of the implanted bolt at the level of the planned target point was reduced from a mean of 3.8 ± 2.5 mm to 1.6 ± 0.9 mm.CONCLUSIONSThis QA framework helped to isolate and quantify the factors introducing inaccuracy in SEEG implantation, and to monitor ongoing accuracy and the effect of technique modifications.

OBJECTIVESurgery for low-grade gliomas (LGGs) aims to achieve maximal tumor removal and maintenance of patients’ functional integrity. Because extent of resection is one of the factors affecting the natural history of LGGs, surgery could be extended further than total resection toward a supratotal resection, beyond tumor borders detectable on FLAIR imaging. Supratotal resection is highly debated, mainly due to a lack of evidence of its feasibility and safety. The authors explored the intraoperative feasibility of supratotal resection and its short- and long-term impact on functional integrity in a large cohort of patients. The role of some putative factors in the achievement of supratotal resection was also studied.METHODSFour hundred forty-nine patients with a presumptive radiological diagnosis of LGG consecutively admitted to the neurosurgical oncology service at the University of Milan over a 5-year period were enrolled. In all patients, a policy was adopted to perform surgery according to functional boundaries, aimed at achieving a supratotal resection whenever possible, without any patient or tumor a priori selection. Feasibility, general safety, and tumor or patient putative factors possibly affecting the achievement of a supratotal resection were analyzed. Postsurgical patient functional performance was evaluated in five cognitive domains (memory, language, praxis, executive functions, and fluid intelligence) using a detailed neuropsychological evaluation and quality of life (QOL) examination.RESULTSTotal resection was feasible in 40.8% of patients, and supratotal resection in 32.3%. The achievement of a supratotal versus total resection was independent of age, sex, education, tumor volume, deep extension, location, handedness, appearance of tumor border, vicinity to eloquent sites, surgical mapping time, or surgical tools applied. Supratotal resection was associated with a long clinical history and histological grade II, suggesting that reshaping of brain networks occurred. Although a consistent amount of apparently MRI-normal brain was removed with this approach, the procedure was safe and did not carry additional risk to the patient, as demonstrated by detailed neuropsychological evaluation and QOL examination. This approach also improved seizure control.CONCLUSIONSSupratotal resection is feasible and safe in routine clinical practice. These results show that a long clinical history may be the main factor associated with its achievement.

Abstract. The purpose of this research was to analyze the marketing system and marketing channel of chicken eggs and to analyze marketing efficiency based on marketing margin, price share and profit ratio of chicken egg cost in Pematangsiantar Municipality of Simalungun District. This research was conducted for two months, from July to August 2017. The methods used in data collection were: sampling of breeders and other marketing institutions selected by snowballing sampling technique and data collection methods was done by interviewing techniques using questionnaire. Data analysis included: marketing costs, marketing margin,farmer share and profit cost ratio of each marketing channel. The results of this study indicated that there were four marketing channels. The marketing margin on the Channel II showed the smallest cost margin and the largest profit margin so that it showed the largest cost-benefit ratio. The largest farmer share was obtained on the Channel IV but this channel used only the retailers as an intermediate channel (one level) and relatively few exchanged eggs. So it was concluded that the Channel II was the most efficient channel becauseof the smallest cost and that the profits were spread evenly among all the marketing institutions that play a role. The need for chicken eggs in Pematangsiantar Municipality was supplied from outside the city (63.33%) and filled by breeders from within the city(36.66%).

A cross-sectional study from an ectopic tissue of endo-metriosis and normal was examined for immunohistochemistry. This research was conducted from November 2015 until the sample complete. The analysis was performed using Fisher Exact test, p <0.05 was considered to any difference of estrogen alpha receptor expression between endometriosis patients with no endometriosis. REα is more dominant in normal endometrium, whereas in the case of endometriosis in the presence of many negative expression of REα then the assumption that REβ is a receptor that many encountered. There is a dif-ference in the expression of REα between endometriosis with no endometriosis.
