Abstract

Endoskeletal prosthetic foot that was developed at the knee joint by storing energy systems 2 bar mechanism. This technology is analogous to a spring that can be stretched and loosened, store and release elastic potential energy. Storing energy systems to facilitate the activity of normal or brisk walking. 2 bar mechanism consists of two links and a joint with joint function as a link 2 link. Storing energy in the system design of knee joint using a gas spring with the principle of increasing the pressure causes compression of nitrogen gas in the tube and the more energy saved. This study involves a transfemoral amputee object, male gender, age 49 years, height 164 cm, and weight 67.5 kg (without a prosthetic foot). Kadaba's experimental protocol using a protocol with a prosthetic foot on the right and left foot on the normal road speed 0.7 m/s - 1.4 m/s. Study the biomechanics of gait cycle analysis for a brisk walk, torque (Ï„), style (Fx, Fy) and external work (Ew). Knee joint with energy storing mechanism of 2 bar to perform flexion and extension movements, swinging his legs no longer require a large force. This system has been storing energy and energy release in shaping the pattern of walking to be balanced at the moment pre swing and mid swing.

Abstract

PT. Dwi Komala is one of middle-scale industries that producing in footwear product. In production system, waste such as movement waste and excessive transportation, are commonly found and affect to unmet production target. This waste occurs because the work station placement does not consider the production process flow and spatial interconnectedness. One of solutions that can be done to repair the facility layout is redesigning the layout by considering production process flow and the relationship between any space in the layout. The layout of facilities in this company is not made based on the good planning but only adjusting with the existing space, so that irregular layout results. Meanwhile, the facility layout not taking into account the production process flow, production machineries placement and production activity requirement results in larger material handling cost and it will impact on the high production cost and production process time. For that reason, this research aims to produce the proposal of layout design that can minimize the material handling cost (MHC). In this research, the facility is redesigned using Systematic Layout Planning (SLP). The SLP procedure consists of three stages: analysis, adjustment and evaluation. The analysis stage includes material flow analysis, activity relationship chart (ARC), activity relationship diagram (ARD), area requirement analysis and available area analysis. The adjustment stage includes planning the spatial relationship diagram and alternative layout design. In evaluation stage, the evaluation was done on the alternative layout design. Three proposed layout which minimizes material handling cost could be resulted by Systematic Layout Planning (SLP) method. The first proposed layout gives a significant saving of 11.35% compare to existing layout. The second layout results in 31.17% saving while the last layout gives a saving of 32.44%. Thus, the third layout proposal was recommended as the selected layout proposal

Abstract

The Taguchi Method is one of method that is applied in off line control activities in the design ofproduction process stage. In the production process of interior gypsum, there are many handicaps found when gypsum is going to be taken out of the matrix and placed. Thus, it will make loss in both the company and the customers. The goal of this research is to determine influential factors to the produced interior gypsum, to determine Analysis of variance (Anova) and to count Signal to Noise Ratio (SN ratio), to determine the best setting level from the influential factors, and to count the quality loss function for knowing the loss made by handicapped product. This research uses experiment method and the experiment is done in three stages. The first is based on the company setting and uses 30 samples. The second is based on the applied orthogonal array, L8 (27), and uses 4 replications for every level combination. The third is based on optimum setting and uses 10 samples. From the data processing, there is average rise of compressive strength examination up to 12,63 kg/cm2. This optimum setting will reduce the loss experienced by the company and customers. It can be seen from the value of quality loss function gained before and after applying optimum setting.

Abstract

Taylor Spatial Frame (TSF) better known as an external fixation product from several types of fixation devices in the orthopedic field. The Laboratory of Product Planning and Design has manufactured TSF or called OrthoLPPDUNS external fixations. The OrthoLPPDUNS design found that frame instability forming ring-strut angles caused by strut screw rotations was feeling rough due to backlash. The purpose is how to redesign an OrthoLPPDUNS with a Function Analysis System Technique (FAST). FAST method is applied at each stage of starting from the information stage to the interpretation of the results. The OrthoLPPDUNS design with the joint system uses custom components that cause weakness in frame stability. The use of standard components in joint systems can provide solutions to external fixations, although there are still weaknesses in the ring-strut angle. The OrthoLPPDUNS redesign has a better success rate in terms of stability parameters, allowing more precise bone reconstruction.

Abstract

Pekarangan rumah mencerminkan budaya suatu kelompok masyarakat kreatif. Pemanfaatan lahan disekitar rumah tinggal menjadikan komoditas nilai ekonomi akan memberikan dampak bagi ekonomi kerluarga. Lahan perkarangan terbatas melalui budidaya tanaman obat keluarga (TOGA) yang memiliki khasiat obat sangat cocok untuk memenuhi kebutuhan obat keluarga. Tujuan kegiatan pengabdian ini adalah bagaimana memperkenal kepada masyarakat desa Tanjungsari Boyolali dengan budidaya tanaman TOGA `dengan pemanfaatan lahan pekarangan yang tidak memerlukan lahan yang luas dalam upaya persediaan obat herbal keluarga. Pengabdian ini melibatkan pihak Kelurahan, siswa anak-anak Sekolah Dasar (SD), dan mahasiswa kelompok KKN 103 Universitas Sebelas Maret (UNS) Surakarta. Memperkenalkan tanaman TOGA dengan percontohan pemanfaatan lahan pekarangan di SD Negeri 1 Tanjungsari dengan tanaman suruh, daun sereh, dan kunci. Pemilihan tanaman TOGA disebabkan ketersediaan tanaman mudah, tahan terhadap lingkungan dan memiliki khasiat sebagai obat herbal. Dampak kegiatan ini tumbuh kepedulian warga dengan memberdayakan budidaya TOGA sebagai obat herbal. Pelaksanaan program kerja ini disambut antusias oleh warga dan memberikan nilai ekonomi tersendiri bagi keluarga.
