Desain Untuk Disabilitas Perancangan Meja DAYA Untuk Mengakomodir Kebutuhan Mahasiswa Penyandang Tuna Daksa Pengguna Kursi Roda

Abstract —The provision of education that provides opportunities for all students regardless of limitations has been guaranteed by law. Unfortunately, adequate facilities for students with special needs such as wheelchair users in many Higher Institutions are still insufficient, especially in classrooms. This article is a summary of research activities and the design process of the DAYA table that accommodates the needs of wheelchair users in the classroom. The DAYA desk is designed with the Design Thinking methodology, that further elaborate on empathy studies so that the need s of the user are accommodated, so that they can be more independent in following the course of lectures. The design of the DAYA table proves that in designing a product for people with disabilities, ergonomics studies are not enough, because they have to consider the habits and needs of users through empathy studies. These two things are often left untouched by ergonomic studies that focus more on physical parameters alone. Keywords: Design Thinking, Disability, Empathic StudyAbstrak — Penyelenggaraan pendidikan yang memberikan kesempatan bagi semua peserta didik terlepas dari keterbatasannya telah dijamin oleh Undang-Undang. Sayangnya fasilitas yang memadai bagi mahasiswa berkebutuhan khusus (disabilitas) seperti pengguna kursi roda di berbagai perguruan tinggi masih belum mencukupi, terutama di ruang kelas. Artikel ini merupakan rangkuman kegiatan penelitian dan proses desain dari produk meja (meja DAYA) yang dapat mengakomodasi kebutuhan peserta didik pengguna kursi roda di dalam kelas. Meja DAYA didesain dengan metodologi Design Thinking dengan lebih mengelaborasikan studi empati agar kebutuhan mahasiswa tersebut dapat terakomodasi. Hasil dari penelitian ini dapat membantu mahasiswa disabilitas agar dapat lebih mandiri dalam mengikuti jalannya perkuliahan. Desain dari meja DAYA membuktikan bahwa dalam mendesain sebuah produk untuk kaum disabilitas, studi ergonomi saja tidaklah cukup, karena harus mempertimbangkan kebiasaan dan kebutuhan dari pengguna melalui studi empati. Kedua hal ini sering kali tidak tersentuh oleh studi ergonomi yang lebih fokus pada parameter fisik semata.Kata Kunci: Design Thinking, Disabilitas, Studi Empat

Analisa Kerusakan Dan Perbaikan Power Train Pada Unit Excavator Kobelco SK200-5

Power train is a drive mechanism that works together to transmit power from the engine to the final drive, how the power train works when the engine rotates drives the main pump to circulate pressurized oil from the tank to the control valve and is passed on to the travel motor to drive the final drive. A visual inspection of the components is carried out to ensure that the power train components are damaged which causes the unit to stutter, along with several visual inspections of the power train components including checking the Control Valve, Idler, and Motor Travel. Based on the results of checking the power train has damage to the worn sprocket teeth. This damage is caused by soil or mud that sticks and hardens resulting in erosion of the components which makes the components wear out, the service life has exceeded the limit. Repairs to this sprocket component require replacing it with a new part because the Kobelco Sk200-5 excavator uses a solid type sprocket

RESPONSE OF SUB1 INTROGRESSION LINES OF RICE TO VARIOUS FLOODING CONDITIONS

Two types of floods can be happen in rice crops, i.e. flash floods and  stagnant floods. Flash floods cause complete submergence for up to 2 weeks, while stagnant floods (SF) could partially submerge part of rice  plant. To overcome yield loss due to the floods, introgression of SUB1 gene, known as a gene suppressing cell elongation and carbohydrate  metabolism, to rice genotype can increase plant tolerance to complete submergence for 10 days or more. The study aimed to evaluate the response of 18 rice genotypes, including the recently developed sixth pair SUB1 near isogenic lines (NILs) of mega-rice varieties (Swarna, Sambha Mahsuri, IR64, TDK1, BR11, and CR1009), to various flooding conditions. The rice genotypes were planted at field ponds at Los Banos, Philippines, in the wet season (WS) of 2009. The treatments were 15 days  submergence, SF, SF follows submergence and normal conditions. Each treatment was arranged in completely randomized block design with threereplications. The results showed that the SUB1 introgression rice lines had higher survival compared to the non-SUB1 and did not much elongate their shoots during submergence. Nevertheless, under SF the rice genotypes should elongates their shoots to allow restoring contact with the air. SF and SF follows submergence decreased the panicle number, grainnumber per panicle and panicle fertility. Consequently, the yield declined. It suggests that sensitive genotypes are mostly sourcelimited during grain filling. The SUB1 introgression lines had higher chlorophyll concentration and less depletion in soluble sugar and starch after submergence. Under SF, soluble sugar and starch contents between the SUB1 NILs and  non-SUB1 lines were not significantly different. Introgression of the SUB1 into high-yielding varieties improved submergence tolerance without affecting yield potential. The study indicates that introgression of the SUB1 into taller type rice varieties should be done to compensate the effect of suppressed elongation

Design of a Sky Camera-Based Cloud Monitoring Camera at the Agam Space and Atmospheric Observation Station, Bukit Kototabang

Indonesia is a center of convection and acts as a driving force for global atmospheric circulation due to its geographical position. Moreover, Kototabang Hill is one of the national strategic areas in the equatorial atmospheric observation room with limited cloud cover data so that tools and development are needed to meet these data needs. Sky Camera for the purpose of observing clouds (Cloud Camera) is urgently needed to complement the need for cloud cover data to support observation and research activities in the field of the atmosphere. The Cloud Camera design is done by modifying the CCD Camera with several supporting devices including fish eye, solar tracker, sun filter and dome. Evaluation of the urgency of these enhancements is discussed in this paper. Among the four combinations of using supporting instruments (dome and sun filter) for the Cloud Camera device, the best image obtained is the device that uses a sun filter and without a dome.
