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 (τ), 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. IKAD is a company that produces ceramic tile. Quality decreasing is occurred on some Critical To Quality (CTQ) in a part of kiln. Kiln process itself was the last process and the most vital in determining final output of ceramic tile. Realizing the importance to the quality of kiln process, hence needed a problem solving method to improve and control process which taking place in Department Plant 3 so the amount ofdefect product can be minimized to achieve zero defect. The method to solve the problem is Six Sigma method that consist of Define, Measure, Analyze, Improve, and Control (DMAIC) phase. DMAIC phase begins with identifying customer needs to determine priority ofCTQ. Then measuring the sigma level, stability and process capability ofpriority CTQ. On the analyze phase, cause effect diagram is used to find failure cause analysis of CTQ, and then Failure Modes Effect Analysis (FMEA) tool is used to analyze the failure. On the final phase, improvement plan and process control act is done for company. The result ofthis research from Define phase is dash away as the priority ofCTQ. On the Measure phase known that sigma level in the month of January 2006 equal to 3,46 sigma and decrease to 3,24 sigma in Februari 2006. At that both period, process condition is not stable but capable enough if seen from Cp and Cpk value. On the Analyze phase is obtained the information that many factors like process or method, man, material, measurement, mother-nature, also machine and equipments are supposed causing instability and incapability of kiln process. Improve suggestions for managerial and technical side are given and Control suggestions to guarantee the quality of kiln process are also given on the Improve and Control phase.

Abstract

TELKOM always make an effort to fulfill the society need upon products and services of fixed phon. The effort of TELKOM such as repair the old network (existing) and add the new network in certain area that have high potency of demand, such as in Gentan, Purbayan, Colomadu, Jaten and Kaliyoso. Those reparation and increament of the network give chances to customer of TELKOM who want to have a new installation of fixed phone (PSB). Process of PSB fixed phone in existing area is different with new network area. In new network area, TELKOM not yet had standard business process, and this is stimulate some problems, such as delayed activation, untidy network, lack of access of network and escalation (fatal cancel).Evaluation and improvement of business process are required in order to prevent and to reduce some problems. Evaluation and improvement of business process are conducted using the method of Fault Tree Analysis (FTA) and Malcolm Baldrige National Quality Award (MBNQA). Based on the result of FTA and MBNQA, there is improvement on business process new installation (PSB) of fixed phone in new network area by adding Drop Wire withdrawl in early stage.

Abstract

One of the biggest barier which faced by company to apply total quality is cultural barricade. Many company try to implement total quality , entangling employees at all level with providing training to guarantee employees to be skilled, where this matter is done just to flatten their ability. There is no effort to make a freshment in doing something. In other words, there is no effort to change company culture.

Abstract

Alat ukur ini diharapkan dapat digunakan untuk evaluasi kinerja dosen sebagai dasar penyusunan kebijakan jurusan TI UNS dalam pengembangan sumber daya manusia. Atribut awal mengacu pada butirbutir BAN-PT (Borang), portofolio dosen dan Ekivalen Waktu Mengajar Penuh (EWMP). Pentingnya alat ukur kinerja dosen akan menjadi alat evaluasi jurusan dan dapat digunkan sebagai perbaikan internal serta realisasi penjaminan mutu jurusan TI UNS. Penelitian ini terdiri dari lima tahap : (1). identifikasi atribut, (2). pengelompokan atribut (3). penetapan atribut dengan Focus Group Discussion (FGD), (4) desain alat ukur. Dari identifikasi atribut diperoleh 22 atribut (studi pustaka) dan 14 atribut (masukan dosen). Pengelompokan atribut dilakukan berdasarkan atribut terukur dan tidak terukur. Atribut terukur ini akan digunakan pada tahap selanjutnya karena supaya dalam perancangan alat ukur memiliki atribut penyusun yang jelas tingkat pengukurnya sehingga penilaiannya tidak bersifat subjektif dan berdasarkan bukti. Dari FGD menetapkan 2 atribut yang tereliminasi. Penelitian ini menghasilkan alat ukur yang tersusun atas 4 bidang dengan total 29 atribut, yaitu: (1) pendidikan dan pengajaran terdiri dari 16 atribut, (2) penelitian dan pengembangan karya ilmiah terdiri dari 7 atribut, (3) pengabdian kepada masyarakat terdiri dari 2 atribut, serta (4) kegiatan penunjang Tri Dharma Perguruan Tinggi terdiri dari 4 atribut. Berdasarkan uji coba alat ukur nilai performance dosen TI UNS pada bidang penelitian dan kegiatan penunjang Tri Dharma Perguruan Tinggi mendapatkan skor 2 yang artinya masih dalam level cukup. Oleh karena itu diharapkan pihak TI UNS lebih mengarahkan atau memberikan kebijakan pada kegiatan yang berkaitan dengan penelitian yang masih memiliki nilai yang kurang dalam hal karya yang dihasilkan dalam bentuk buku ber ISBN, Kegiatan riset dosen yang digunakan industri, dan Karya-karya yang dipatenkan serta kegiatan penunjang Tri Dharma Perguruan Tinggi dalam hal mengikuti organisasi profesi dan prestasi dosen dalam mendapatkan penghargaan.

Abstract

Oyster mushroom is one of the most popular mushroom consumption cultivated in Indonesia. The cultivation process of oyster mushrooms is relatively easy , and also marketable because it has the nutrients and good nutrition. Oyster mushrooms is perishable foodstuffs. A few days after harvesting, oyster mushrooms will be amended, color changes to brown, becoming soft texture, and appeared unpleasant aroma. To overcome this, it is necessary to oyster mushroom processing innovation into alternative food products that have high sales value and longer shelf life. One alternative diversification of processed fresh oyster mushrooms is powdery mildew . To cultivate oyster mushrooms into powdery mildew, in this study focus to design a dryer oyster mushrooms with solar energy ( Solar dryer) and applying the grinder. Drier and grinder oyster mushrooms  was tested in groups of oyster mushroom farmers in the Tambak village Boyolali . Solar drier, can drying fresh oyster mushrooms with a capacity of 10 kg within a period of 50-72 hours. Oyster mushrooms grinder can be used with a capacity of 120 grams with a flouring 180 seconds
