PENYEBAB CHANGE ORDER PADA PROYEK KONSTRUKSI BANGUNAN AIR WILAYAH DKI JAKARTA
Authors: Putri Ivana Ramayanti Hendratno , Waty Mega 
Published: March 2021

Change orders are proposals for additional / less work where the main work does not follow the initial design or there are new proposals for new work at all (Pusat Pendidikan dan Pelatihan Sumber Daya Air dan Konstruksi, 2017). A contract or agreement has been signed before implementing the project, but changes often occur after and greatly affect the project performance. This change is also needed to be known if it occurs in a water construction project. To control change orders and contract changes, it is necessary to know the causing factors. This study aims to determine these causative factors by compiling a questionnaire distributed to workers in the water construction sector in the area of DKI Jakarta. The questionnaire results were tested for validity and reliability and Ranked by RII (Relative Importance Index) method. With the acquisition of RII above 0.51, the results found that coordination with utility systems (RII 0, 6842), is the main contributing factor to the Change Order in the construction of DKI Jakarta water buildings. ABSTRAKChange order adalah usulan pekerjaan tambah/kurang dimana pekerjaan utama tidak mengikuti desain awal atau terdapat usulan pekerjaan baru sama sekali(Pusat Pendidikan dan Pelatihan Sumber Daya Air dan Konstruksi, 2017). Sebelum pelaksanaan proyek, pihak yang terlibat dalam konstruksi telah menandatangani kontrak atau kesepakatan. Dalam pelaksanaannya, setelah penandatanagnan kontrak seringkali terjadi perubahan-perubahan. Perubahan sangat berpengaruh pada kinerja proyek, perubahan ini juga perlu diketahui terjadi atau tidaknya dalam proyek konstruksi air. Jika perubahan dalam proyek terjadi pada proyek konstruksi air, untuk mengendalikan perintah perubahan maupun perubahan kontrak diperlukan pengetahuan faktor penyebab terjadinya perubahan. Penelitian ini bertujuan untuk mengetahui faktor penyebab dengan penyusunan kuesioner yang disebarkan terhadap pekerja bidang konstruksi air wilayah cakupan DKI Jakarta. Setelah dilakukan uji validitas dan reliabilitas, hasil kuesioner akan diurutkan berdasar tingkat kepentingan dengan metode RII. Dengan perolehan RII diatas 0,51, hasil yang ditemukan bahwa pengkoordinasian dengan sistem utilitas (RII 0, 6842), merupakan faktor penyebab utama Change Order pada konstruksi bangunan air DKI Jakarta.

With the development of technologies, some engineers still have a limit about technologies that can help them on their project. One of the technologies in the construction field is Building Information Modelling (BIM). BIM is an innovation from Information Communication Technology (ICT) in the construction world. Applications from BIM used in this research are Cubicost Take-off Architecture & Structure (TAS) for concrete working volume calculation and Cubicost Take-off Reinforcement Bar (TRB) for reinforcement working volume calculation. In this research, the writer aims to compare the calculation of roof plate working volume between the Building Information Modeling method with the conventional method. On concrete working volume calculation with Cubicost TAS, the calculation has the same number as conventional calculation or having 0% differential. The working volume calculation between Cubicost TRB and conventional calculation has an accurate result with a differential of 0.59% on reinforcement. The calculation process with Cubicost, which has an automatic system, is shorter and not taking much time than the conventional one, which has a step-by-step process and formula that the writer should be studied first.

Published: March 2021

The increase in housing needs is in line with the increase in the population. Residential buildings in Indonesia are only about 1-2 floors, which require shallow foundations to support. Land is one of the important aspects, where it supports the entire building that stands on it. One of the development constraints encountered in Kalimantan is the peat soil. The construction on peatland will cause problems such as low bearing capacity and large deformation, therefore it needs improvement before use. This study aims to find out the overview of shallow foundation settlement with a size of 2 m x 2 m with a depth of 1 m in untreated soils with a thickness of 6 m and in stabilized peat soils. Stabilization used by 10% of the dry weight of the soil with a content of 30% lime + 70% ash husk rice. Calculation of the settlement in stabilized peat soil, there’re 5 variations of stabilization thickness ranging from 2 m – 6m. Within 30 years, the total settlement of untreated peat soil by 1,25828 m, as well as for stabilizing peat soils with a thickness of 2 m - 6 m experienced a total settlement of 0,534587 m to 0,379714 m. Peningkatan kebutuhan rumah tinggal selaras dengan peningkatan jumlah penduduk. Pada umumnya bangunan rumah tinggal di Indonesia hanya berkisar 1- 2 lantai, dimana membutuhkan fondasi dangkal untuk menopang beban. Tanah merupakan salah satu aspek penting, dimana tanah menopang seluruh bangunan yang berdiri diatasnya. Salah satu kendala pembangunan yang ditemui di Kalimantan adalah lapisan tanah gambut. Pembangunan bangunan diatas tanah gambut akan menimbulkan masalah seperti daya dukung yang rendah serta penurunan yang besar, maka dari itu perlu perbaikan sebelum digunakan. Penelitian kali ini bertujuan untuk mengetahui sebuah gambaran mengenai penurunan fondasi dangkal dengan ukuran 2 m x 2 m dengan kedalaman 1 m pada tanah gambut asli (untreated soil) dengan ketebalan 6 m serta pada tanah gambut yang telah distabilisasi. Stabilisasi yang digunakan sebesar 10% dari berat kering tanah dengan kadar 30% kapur + 70% abu sekam padi. Perhitungan penurunan pada tanah gambut yang telah distabilisasi, ada 5 variasi ketebalan stabilisasi mulai dari 2 m – 6m. Dalam jangka waktu 30 tahun, penurunan total tanah gambut asli sebesar 1,25828 m, serta untuk tanah gambut stabilisasi dengan ketebalan 2 m – 6 m mengalami penurunan total sebesar 0,534587 m sampai 0,379714 m.

Published: March 2021

The high growth rate of vehicles gives direct effect on high road traffic. The capacity of Surabaya-Gresik Highway, which is designed with 2 lanes on each lane, is no longer able to accommodate the existing traffic load. This is proven by frequent long traffic jams on Jalan dr. Wahidin S.H. Therefore it is the right time to construct the underpass.The purpose of this research was to define the peak hours, the degree of saturation, and the level of service that occurred on the road section of Dr. Wahidin S.H to the intersection of Gresik Grand Mosque due to the construction of the underpass in GKB Gresik. The method used in this study was identification of traffic character, traffic survey, and analysis of traffic performance of signalized intersections using the Indonesia Highway Capacity Manual. The results of the study were morning and afternoon peak hours. In the existing condition in 2020 the value of Saturation Degree (DS) was 0.858 > 0.75 (LOS) E. In 2026 in which it is 5-year prediction by using management of traffic engineering the value of degree saturation (DS) was 0.744 < 0.75, level of service (LOS) C. Conditions after management of traffic engineering with adjustment of traffic light time cycle at the intersection of Jl. Dr. Wahidin S.H. – Jl. Gresik – Babat – Jl. Mayjen Sungkono, widening of intersection geometry and the operation of left and right side frontage and setting of Traffic Signaling Equipment (APILL) showed a level of service (LOS) C, stable flow, but limited speed.

Objetivo: Avaliar e revisar a correlação imune da disbiose na progressão do câncer de mama (CM). Revisão bibliográfica: A flora bacteriana contribui positivamente para as funções nutritivas, imunomoduladoras e metabólicas do organismo, entretanto possui um equilíbrio que se interrompido pode resultar em consequências sistêmicas, incluindo efeitos pró-carcinogênicos. Existe relação comprovada do microbioma intestinal em equilíbrio e da manutenção da saúde do hospedeiro, não apenas por interações locais, mas por meio alterações metabólicas sistêmicas, com produção de metabólitos envolvidos na oncogênese ou na supressão tumoral, e por meio da modulação do sistema imune e dos processos inflamatórios. Os resultados sugerem uma ligação entre disbiose e CM, podendo influenciar em implicações diagnósticas e terapêuticas. Considerações finais: Dessa forma, a disbiose presente em diferentes tecidos é passível de afetar outros órgãos, e cada perfil pode afetar o sistema imune distintamente - ou exacerbando-o, ou suprimindo-o. No entanto, ainda são necessários estudos com maior enfoque na pesquisa sobre o perfil de disbiose de cada paciente, para posteriormente, reconsiderar a análise no estadiamento do CM. Além disso, há associação da alteração da microbiota própria do tecido mamário com o risco do desenvolvimento do CM, apesar de não se saber ao certo o mecanismo.

Hyperperfusion and intracranial hemorrhage after burr hole surgery of chronic subdural hematoma
Authors: Shimizu Yu , Tokuda Kazuhiko , Cheho Park 
Published: March 2021

Background:
Chronic subdural hematomas (CSDHs) mainly occur in elderly people and usually develop after minor head injuries. CSDH can be cured by a relatively simple burr hole surgery. Rarely reported, hemorrhagic postsurgical complications include subarachnoid, intracerebral, intraventricular, and remote cerebellar hemorrhages. The causes of such uncommon complications are difficult to explain and remain poorly understood.

Case Description:
We report the case study of an 89-year-old man with CSDH who presented with the right hemiparesis. He underwent burr hole surgery with a closed-drainage system. A computed tomography (CT) scan conducted the following day demonstrated an acute intraventricular hemorrhage and hyperperfusion of the ipsilateral hemisphere.

Conclusion:
This is a rare case of an acute hematoma in the ventricle following drainage of a CSDH. The likely mechanism of this intraventricular hemorrhage could be that the drainage of the hematoma produced a movement of the ventricle and hemisphere accompanied by hyperperfusion.

Background:
Ependymomas are rare tumors originating from neuroepithelial cells lining the wall of the ventricles or central canal of the spinal cord. While these tumors mainly occur within the central nervous system (CNS), there are occasional reports in children and young adult patients with a primary tumor occurrence outside of the CNS. Ependymomas of the sacrococcygeal region have been infrequently described in the literature with no standard of care established. We present a case report and review of the literature regarding this rare entity.

Case Description:
A 24-year-old woman presented with right gluteal pain worsened by sitting and a palpable soft tissue mass of the sacrococcygeal region. Magnetic resonance imaging revealed a 3.7 cm cystic mass centered in the right gluteal region. She underwent a biopsy at an outside institution, with histology revealing myxopapillary ependymoma. The patient was referred to our hospital and underwent an interdisciplinary neurosurgical and orthopedic oncology en bloc resection of the ependymoma, which intraoperatively appeared to originate from the coccygeal nerve.

Conclusion:
In the present report, the authors demonstrate that a myxopapillary ependymoma may present as an isolated gluteal mass attached to the coccygeal nerve, without frank CNS involvement. Furthermore, an interdisciplinary approach to surgical resection of this lesion appears to represent an effective treatment modality.
