Authors: Agustiawan Iwan , Riyadhi Ardi Adhiguna 
Published: October 2021

Abstrak Stabilizer bar berfungsi mengurangi besarnya sudut rolling, sehingga diharapkan kendaraan lebih stabil. Tujuan yang ingin dicapai dari penelitian ini adalah mengetahui kekuatan stabilizer bar akibat body roll kendaraan dengan pemodelan dan simulasi serta analisis menggunakan bantuan software solidworks. Metode yang digunakan adalah mengidentifikasi karakteristik fisik, beban, tumpuan dan material yang digunakan untuk proses pemodelan serta simulasi sederhana menggunakan software solidworks sehingga dapat memperoleh tegangan geser dan faktor keamanan. Sebagai pembanding terhadap model dan simulasi solidwork, tegangan geser maksimum yang terjadi dihitung secara manual berdasarkan momen puntir dan momen lentur yang bekerja secara simultan dalam stabilizer bar. Hasil penelitian ini menunjukkan bahwa ketika kendaraan mengalami body roll sebesar 3,51° dimana stabilizer bar terpuntir 2,62° dan mengalami tegangan geser dan faktor keamanan dari perhitungan manual, yaitu 52,47 MPa dan 9,39 untuk beban statis, 104,94 MPa dan 4,69 untuk beban dinamis. Berdasarkan analisis menggunakan software solidwork tegangan geser dan faktor keamanan, yaitu 50,05 MPa dan 8,96 untuk kondisi statis, 100,1 MPa dan 4,48 untuk kondisi dinamis. Berdasarkan prediksi menggunakan persamaan regresi linier, maka sudut body roll kritis yang dapat dicapai adalah sebesar 45,99° ketika stabilizer bar mulai mengalami deformasi plastis. Kata kunci : Stabilizer Bar, Anti-Roll Bar, Solidworks Abstract The stabilizer bar functions to reduce the amount of rolling angle, so that the vehicle is expected to be more stable. The purpose of this research is to determine the strength of the stabilizer bar due to vehicle body roll by modeling and simulation and analysis using Solidworks software. The method used is to identify the physical characteristics, loads, supports and materials used for the modeling process and simple simulations using solidworks software so as to obtain shear stress and safety factors. As a comparison to the solidwork model and simulation, the maximum shear stress that occurs is calculated manually based on the torsional moment and the bending moment that work simultaneously in the stabilizer bar. The results of this study indicate that when the vehicle experiences a body roll of 3.51 ° where the stabilizer bar is twisted 2.62 ° and experiences shear stress and safety factors from manual calculations, namely 52.47 MPa and 9.39 for static loads, 104.94 MPa and 4.69 for dynamic loads. Based on the analysis using solidwork shear stress software and safety factors, namely 50.05 MPa and 8.96 for static conditions, 100.1 MPa and 4.48 for dynamic conditions. Based on predictions using linear regression equations, the critical body roll angle that can be achieved is 45.99 ° when the stabilizer bar begins to undergo plastic deformation.

Published: October 2021

Need for corn is increasing, both for food, animal feed, and industrial raw materials. This is an opportunity as well as a challenge for the government in increasing corn production towards sustainable self-sufficiency. Superior varieties are one of the components that can significantly increase yield. Hybrid varieties have a higher yield potential than composites so that the use of hybrid corn seeds can increase the yield of corn per crop area. The Agricultural Research and Development Agency (Balitbangtan) has produced hybrid maize varieties with high yield potential, which are no less competitive with other private hybrid maize, but they are not well disseminated. In order to obtain added value for farmers and the development of Balitbangtan corn seeds, NASA 29's hybrid corn seed propagation was carried out at the farmer level. The study was carried out in Salukayu Village, Papalang District, Mamuju Regency in 2018 covering an area of ​​1 ha. The results showed that corn seeds were 1.5 tons / ha. The Nasa 29 hybrid maize seed propagation farm is economically feasible and profitable, as indicated by the R / C value of 2.35, TIP 637 kg / ha, TIH Rp. 10,623, - / kg and IK Rp. 88,985, / day. The study of the propagation of the NASA 29 hybrid maize seed was financially feasible and the economic benefits were high and efficient.

Dengan kondisi daerah yang sedemikian rupa maka muncullah di Kabupaten Mojokerto ini penggemar offroad, khususnya roda dua. Seperti halnya yang dilansir oleh MOJOKERTO, FaktualNews.co pada tahun 2017 tepatnya pada hari minggu tanggal 16 Juli event yang dilaksanakan di Desa Ketapanrame Kecamatan Trawas diikuti oleh sedikitnya 1500 crosser menjajal medan yang ada didaerah tersebut walapun bukan sebuah kompetisi. Terkait dengan balap motocross terutama sirkuit yang ditempati, sebuah tema yang berhubungan dengan aspek tersebut haruslah diperhatikan. Untuk menciptakan bangunan yang sesuai dengan fungsi dan kondisi dari kawasan ini maka penulis mengusung tema arsitektur organik yang menjadikan bentuk bangunan yang sesuai dengan lingkungan sekitar. Metode yang dipilih untuk perencanaan dan perancangan ini adalah metode deskriptif dan analisa yang mana dalam pelaksanaannya segala bentuk studi yang telah dilakukan baik itu lapangan dan literatur memberikan output berupa analisa,antara lain yaitu analisa studi banding dan tapak yang digunakan untuk perancangan. Untuk konsep rancangan bangunan motocross ini mengambil konsep makro metafora dari bentuk daun yang selanjutnya dikaitkan dengan prinsip arsitektur organik antara lain building as nature.

Pathophysiology and surgical treatment of spinal adhesive arachnoid pathology: patient series
Authors: Koyanagi Izumi , Chiba Yasuhiro , Uemori Genki , Imamura Hiroyuki , Yoshino Masami , Aida Toshimitsu 
Published: October 2021

BACKGROUND
Spinal adhesive arachnoid pathology is a rare cause of myelopathy. Because of rarity and variability, mechanisms of myelopathy are unknown. The authors retrospectively analyzed patients to understand pathophysiology and provide implications for surgical treatment.

OBSERVATIONS
Nineteen consecutive patients were studied. Thirteen patients had a secondary pathology due to etiological disorders such as spinal surgery or hemorrhagic events. They received arachnoid lysis (4 patients), syringo-subarachnoid (S-S) shunt (8 patients) with or without lysis, or anterior decompression. Three of them developed motor deterioration after lysis, and 6 patients needed further 8 surgeries. Another 6 patients had idiopathic pathology showing dorsal arachnoid cyst formation at the thoracic level that was surgically resected. With mean follow-up of 44.3 months, only 4 patients with the secondary pathology showed improved neurological grade, whereas all patients with idiopathic pathology showed improvement.

LESSONS
The idiopathic pathology was the localized dorsal arachnoid adhesion that responded to surgical treatment. The secondary pathology produced disturbed venous circulation of the spinal cord by extensive adhesions. Lysis of the thickened fibrous membrane with preservation of thin arachnoid over the spinal veins may provide safe decompression. S-S shunt was effective if the syrinx extended to the level of normal subarachnoid space.
