Karak is one of food products favored by many indonesians. Demands for this traditional meals is still high especially in the rainy season, so this food is good to be developed. In some karak cottage industries especially in urban areas, their production process has advanced, but they are still unable to fulfill high demand. In this research, Toyota Business Practices (TBP) is used to identify the root cause problem and propose improvement actions for the problem. Based on TBP’s results, the problem occurs in the cutting station where there are 900 pieces of karak which are too small or large and sloping. The root cause problem identified are the lack of a standard size for karak and equipment used is still a regular knife. Accordingly, the proposed corrective action are the creation of standards karak size and design of cutting tools to increase productivity and neatness in the cutting station.

Stirling engine technology is an old technology that was developed to be a power back. In America and in Europe the development of Stirling engine has been done so far by utilizing production technology and advanced materials. This research uses the technology micro-scale workshop and uses the other engine components that exist on the market to accommodate the volume Stirling engine design compressor size. In performance testing, this study used cranckshaft axle load testing methodology. Testing is done by 5 (five) times. From the data at average constant speed, travel time and expense it can be calculated that the engine power is generated. The results of this study produced a prototype Stirling engine with a pressure of 1 bar gamma type. In addition to the prototype machine, the performance measurement analysis used as the input source in the development later of the Stirling engine to produce competitive and cheap

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

Kualitas produksi dan performa perusahaan dapat ditingkatkan dengan mengurangi pemborosan yang ada di perusahaan. Dalam penelitian ini, metode yang digunakan adalahFMIC (Flow Material Information Chart) untuk menghitung kapasitas mesin, produktivitas operator dan TSK (Tabel Standar Kerja)untuk mengukur beban kerja operator. Hasil yang diperoleh dari penelitian ini adalah kapasitas mesin terbesar adalah mesin frying dengan jumlah 7935,75 kg. Nilai produktivitas operator tertinggi adalah operator proses frying dengan jumlah 881,75 kg/orang. Nilai cycle time semua operator selalu lebih kecil atau sama dengan nilai takt time mesin sehingga kerja operator masih termasuk ke dalam kategori kerja ringan. Nilai not value work yang didapat untuk tiap operator selalu lebih besar daripada nilai value work. Kesimpulan yang didapat dari penelitian ini adalah diperlukan upaya untuk mengurangi jumlah operator ataumenambah jumlah mesin packing. Selain itu perlu dibuat penutup untuk mesin molen di stasiun coating sehingga jumlah waste mentah dapat dikurangi

This research investigates the problem of electromagnetic noise on myoelectric device. This myoelectric device has a low pass filter response (Butterworth type) with cut-off frequency (fc) 6 Hz and passing 8 volt signal. The passed signal, then amplified by a differential amplifier for 150 times into 1,2 Volt (20% noise captured system). So we require an approach to electromagnetic shielding to reduce interference from the outside that enter into the device system. In this study utilizing an experimental design using full factorial experiment methods to determine the effect of the type of bahan, the frequency response, and the interaction to the performance of shielding. The experiment results showed that each element and their interactions, significantly affected the value of the shielding performance. Aluminium foil air cell bubble has the highest shielding performance with the average performance of shielding efficiency of 94,80887 %. This bahan used for shielding socket design proposal which based in the Wisconsin department of health service and American heart association standard.

Design for Manufacturing and Assembly (DFMA) is a method to evaluate the design of productwith considering the ease of manufacture process and the assembly process. UNS LPPD Hand isprosthetic hand with the function and shape that has likely the original hand man. UNS LPPD Hand is developed by the Laboratory Planning and Product Design of Sebelas Maret University (Laboratorium P3 UNS). From the conceptual design of prosthetic finger by Cahyadin (2016), the prototype can't do the movement flexed according with the design objectives and there are some components that not required. Therefore, there are some components that must be modified or eliminated. The modified component is phalanx of media and eliminated components are short and long pin holder The result is improvement of design prosthetic finger that 2 components are fixed and 4 components are eliminated, and reducing the process from 99 steps to 79 steps

The experiment has a purpose to observe performance of indirect passive solar dryer, so that it can raise the effectivity of drying process without decreasing the nutrition of biopharmaca rhizome. This observation using a fresh turmeric rhizome as an experiment matter. Each process using 2 kg turmeric rhizome. Turmeric rhizome cut alongside for about 3-5 mm. The design of this experiment using a factorial design with two influential factors which is can be control, that is the size of inlet hole and exhaust. Response of this experiment show by moisturising level from turmeric rhizome. The measuring of moisturizing level in each treatment are doing every 8 hours. The sample of turmeric rhizome are take for 3 sample. The trial result show that the temperature of dryer equipment is reached for 53.5 celcius. Moreover, the rate air flow for about 1,02 m/s in inlet hole and 0,43 m/s in exhaust hole. There are significant difference between inlet and exhaust level, moreover there is an interaction between inlet and exhaust hole to decline moisturizing level of simplisia turmeric. The optimal setting of this dryer equipment can be obtain with some action of closing the inlet hole for about ¾ and exhaust hole for about 1/2 from its part. The position of the rack didn’t influence the rate of decrease water content.

To increase the production of simplicia, has been designed and fabricated rhizome cutting tools with 5 parallel blades. Based on testing, there were still weaknesses known in the knife-blade thus inhibiting the cutting process. At the beginning of the research showed that the bottleneck caused by the cutting blade is too thick to be a narrow gap between the blade and the friction becomes large rhizome pieces. Thinning of the blade is not necessarily done because it will weaken the blades. This research aims to provide design solutions that is able to overcome a problem of the blade is. To obtain a solution to the existing contradiction problems, TRIZ method was used. The first step taken is identification the problem include the study of literature and direct observations of turmeric rhizome cutting tools. Then followed by determining technical requirements of design, resolve problems that occur contradiction, the last is preparation of design concept and the determination of the design specifications. The results of this research is produce design concept and resolve most issues contradictions mainly on cutting blades. By using TRIZ method, the design of cutting blades not occurring deflection, because the shape of blade was thin and there was additional features that serve to regulate the tension of cutting blades.
