Basan Kulon, Desa Sambi Kecamatan Sambirejo, Kabupaten Sragen merupakan daerah dengan predikat zona merah tentang kesejahteraan masyarakatnya. Dusun ini terletak Di kaki gunung Lawu sehingga secara geografis terletak di dataran tinggi dan perbukitan. Wilayah ini tidak dilalui jalur PUAM Pemerintah, sehingga untuk mendapatkan air bersih harus mengandalkan air sungai yang dialirkan menggunakan pipa PVC dengan jarak 5 km dari dukuh tersebut. Pada saat musim kemarau warga kesulitan mencari air karena sungainya kering, sedangkan saat musim penghujan air sungai menjadi keruh kerena telah terkontaminasi dengan air hujan. Kondisi ini telah terulang terus menerus setiap tahun dan belum ada solusi. Bak penampung akan berfungsi untuk media penampungan sementara saat musim penghujan sehingga air menjadi tidak keruh dan pada musim kemarau dapat menjadikan tampungan dengan kapasitas besar, baik air cadangan dari sungai ataupun bantuan/swadaya pembelian air melalui tangki dari pemda sehingga masyarakat dapat mengalirkan air setiap saat. Dengan peningkatan kualitas air bersih yang digunakan oleh warga diharapkan dapat meningkatkan taraf kesehatan dan menjadikan lingkungan Dusun Basan Kulon lebih produktif.

Cattle farms produce waste which consisted of cow excrement in the form of solid, liquid, gas or cattle feed residual. Utilization of cow manure waste into organic compost requires proper processing technology which includes the technology of solid manure pulverizing and the technology of mixing raw materials. This research focuses on designing a cattle dung waste pulverizer. The methods used are numerical calculations, simulations using the Fusion 360 software, and fabrication based on Design for Manufacture and Assembly (DFMA). The main parts of the design include pulverizer, engine frame, cover (input and output hoppers), diesel motor, transmission belt and pulley. The safety factor obtained for the frame section was 4,645, for the cover section was 11.3, and for the counter section was 2,009 with assumptions of uniform load distribution of 20000 N. The power required for the design was 6.6 HP. The cattle dung waste pulverizer was built and tested using a diesel motor with a maximum power of 13 HP. The cattle dung waste pulverizer's capacity was 1500 kg/hour.

Garbage has certainly been a classic problem which tends to get worse, especially in Jabodetabek area. Various attempts were made to solve the waste problem in the cities. This raises the writer's desire to make a tool that can clean trash in the river automatically, far-reaching, and effectively, namely the lifting garbage conveyor. With this design, garbage can be cleaned continuously because of the automatic system. Even if the volume of garbage in the river increases, the tool can increase the speed of cleaning the garbage by itself. With the sensor system, the tool can continue to operate, without allowing trash to accumulate, using energy effectively, and not requiring a lot of human labor. This tool is designed to cover the entire river and it is capable of being assembled. Because the tool can run automatically, it only takes 1 to 2 workers whose to supervise and do not need to work physically. This tool is easy to operate. To start this tool, you don't need special skills such as the ability to drive when using an excavator.

Energi terbarukan merupakan energi alternatif yang bersih, bebas polusi, aman dan ketersediaanya tidak terbatas. Energi angin merupakan salah satu energi terbarukan. Pemanfaatan energi angin dilakukan dengan menggunakan turbin angin salah satunya savonius. Turbin savonius memiliki kekurangan pada nilai koefisien daya (Cp) yang rendah. Penambahan konfigurasi posisi dan lokasi slotted blades dapat meningkatkan nilai Cp. Untuk memaksimalkan desain turbin angin savonius maka perlu dicari faktor yang paling berpengaruh terhadap nilai Cp. Penelitian ini bertujuan untuk menganalisis signifikansi unjuk kerja turbin angin savonius dengan konfigurasi slotted blades secara statistik. Pengujian hipotesis dari dua faktor yang mempengaruhi nilai Cp dilakukan dengan menggunakan metode pengujian statistik Kolmogorov Smirnov Test, Normalitas test, analysis-of-variance (ANOVA) linier, one-way ANOVA menggunakan software SPSS 22. Hasilnya menunjukkan bahwa lokasi slotted blades berpengaruh secara signifikan terhadap nilai Cp (Sig. 0,000 kurang dari 0,05). Terdapat interaksi antara kedua variabel uji posisi*lebar (Sig. 0,000 kurang dari 0,05). Posisi slotted blades lebih berpengaruh signifikan terhadap nilai Cp karena nilai Sig. 0,000 lebih rendah dari lebar slotted blades 0,011

Manual material handling activities one of them is soy porridge filtration. Important research was conducted to provide interventions reviewed from aspects of NBM, biomechanics, NIOSH and fuzzy biomechanics to NBM as the purpose of this study. This research method takes a saturated sample of 24 respondents, observation and documentation regarding working posture, dissemination and withdrawal of NBM closed questionnaires, assessing biomechanics from the aspect of Fcompression with Fshear, and evaluating activities with NIOSH and integration of fuzzy Mamdani initiated fuzzification, inference, and defuzzification. The study showed that Fcompression 1117.05 N < 3400 N; Fshear of 613.4 N > 500 N were declared to be at risk. The dominant LI value may be at risk of 66.7% for 16 people. Traditional NBM complaints are very painful range 75%-100% at the waist (96%), hips (75%), buttocks (83%), right hands (79%), left thighs and right thighs (75%), left knee (92%), and right knee (100%). Traditional proof of biomechanics following fuzzy biomechanics against NBM, by 93.3%. This activity still has risks, both from traditional biomechanics, NIOSH, NBM, and fuzzy biomechanics to NBM. Therefore, appropriate intervention is needed from the aspect of facilities and work environment in the future

The increasing of infrastructure development causing in increased demand for sand material. On the other hand, the sand still contains many other components such as gravel. The size of good sand according to the Indonesian National Standard (SNI - 03-247-2002) is natural or artificial sand produced by the stone crusher industry with the largest grain size of 5 mm. On the other hand, the lack of infrastructure of the Tanggalan vilage and the small income of the village has resulted in an uneven distribution of the regional economy. Youths and heads of the Tanggalan village see the potential to increase the village's income by making sieving businesses and providing good quality building sand. The manual sieving process takes longer, so it has an impact on the development process as well as from an economic point of view on the long construction costs. So, it is necessary to have a rotary type automatic sieving machine that has a function to separate fine sand grains or according to the criteria requested by consumers with gravel. Rotary type sieving machine with a capacity of 10 m3/hour, so it is expected to meet the demand and accelerating development process. In addition, with this tool, hamlet businesses can be formed to increase hamlet income.Key words: Business, Enhancement, National Standard, Rotary, Sand Sieve.

Currently, bread is one of the alternative staple foods that is quite in demand by the public. This has resulted in the bread making industry being enthusiastically welcomed by business people because it has bright and open opportunities for large and small scales. However, the Micro, Small and Medium Enterprises (MSMEs) industry is unable to compete. One of them is because of the use of technology in the dough kneading process. This article discusses product planning for a horizontal type of bread dough mixer using the Design for Manufacturing and Assembly (DFMA) method and Quality Function Deployment (QFD) analysis where the design is based on design, materials, analysis, and equipment and manufacturing process planning. In this study, the Action Research method, engineering engineering and the Solidwork simulation design software were used. The design of the machine can be used for a stirring capacity of 10 kg and a rotation speed of 40 rpm. The results of the design consist of several main parts, namely the main frame, container, stirrer, motor, and transmission system
