Abstract

Usaha peningkatan nilai tambah ubi kayu dapat dilakukan dengan cara penganekaragaman produk olahan ubi kayu menjadi bahan setengah jadi (produk antara) yang selanjutnya dapat langsung dipasarkan atau menjadi produk makanan siap saji. Saat ini, di Kecamatan Kamang Magek Kabupaten Agam usaha penganekaragaman produk olahan ubi kayu banyak dilakukan oleh industri skala rumah tangga (IRT). Namun, dalam proses pengolahannya beberapa IRT masih menggunakan teknologi sederhana sehingga produktivitas dan pendapatan usaha terbatas pada kemampuan teknologi yang digunakan. IRT Erna (mitra) masih menggunakan metode pengeringan konvensional berupa pengeringan melalui panas matahari. Hal ini akan menyebabkan ketergantungan produksi kerupuk ubi terhadap perubahan cuaca. Ketersediaan teknologi pengering dengan menggunakan panas buatan sebagai pengganti panas matahari belum mampu menjadi solusi pengering kerupuk ubi bagi IRT pengolah kerupuk ubi di Sumatera Barat. Kerupuk ubi yang dikeringkan secara paksa menyebabkan ketidakmerataan suhu pengeringan pada produk kerupuk ubi. Untuk itu, perlu dilakukan introduksi teknologi pengering tenaga surya yang dirancang berdasarkan kebutuhan mitra. Dari hasil kegiatan ini dapat disimpulkan bahwa teknologi yang diintroduksikan mampu meningkatkan produktivitas produksi kerupuk ubi hingga 2 kali lipat dari proses produksi dengan menggunakan teknologi konvensional sebelumnya.

Abstract

The micro, small and medium scale of industrial enterprises for cassava crackers is growing rapidly in Kamang Magek District of Agam Regency. Cassava crackers are the typical crackers which only find in the Agam Regency. The taste is crunchy and can be stored for a long time, making this cracker a special food souvenir. In the process of making, cassava is boiled and pounded so that it becomes pasta. Pasta will be formed and dried in the sun. The crackers that have been formed should be dried in a maximum of 1 day. Today, the makers of cassava crackers are still dependent on sunlight, so they often cannot meet market demand during the rainy season. Therefore, through the IbM (Ipteks bagi Masyarakat) program for the community funded by DIKTI, solar drying technology is introduced by using a type of solar tunnel. The result shows the drying time is 2 times faster than traditional drying process. Hopefully, this technology can help the community of the cassava crackers maker to increase their productivity.

Abstract

This research discusses about designing of counter-flow type gasification stove utilizing biomass municipal solid waste (MSW). The first step of the research process is to formulate the design concept of the gasification stove using the MSW collected in Padang city. The results of the design concept formulation are used to obtain the detail design parameters which is used as the reference for manufacturing the stove. The main designing parameters of the gasification stove are the diameter and the height of the stove. The technical drawing is made according to the designing parameters obtained from the design concept formulation. Base on the technical drawing, the counter-flow type biomass gasification stove was built. The obtained results show that for a large value of updraft air and a small value of downdraft air, the operating time of the stove is long. This condition is obtained in the case of standard air and fuel ratio (AFR<1.5). This results show that the gasification stove efficiency is better in comparison with the conventional one.

Abstract

The food business opportunity is very interesting for home industry entrepreneurs in West Sumatra, a home industry of cassava chips. The step of the cassava chip production process that takes longer time than the other step is the washing process. The cassava washing process is carried out manually because washing device that uses motor drives are not affordable for home industry entrepreneurs. In addition, the cassava washing process makes a physical complaint from the operators. Therefore, this research designs a cassava washer that is affordable for the home industry by considering design methods, ergonomic aspects, and customers' needs. This design is carried out using the Quality Function Deployment (QFD) method to translate the voice of the customer into technical and design characteristics, morphological charts for generating alternative designs, and an objective weighted method for evaluating that alternative. The result of this research is the design of a cassava washer which is more practical because it makes the operator works easier and can save time in the washing process. It is also very affordable, with an estimated cost of production IDR2,397,743.

Abstract

The concentration of carbon dioxide (CO2) gas in the atmosphere continues to increase every year, mainly due to human activities such as burning fossil fuels for energy, industrial processes, and transportation. The development of CO2 gas reduction research continues to be carried out, one of which is the adsorption process using adsorbents. The research was carried out by looking at the effect of variations in activating agent and activation temperature on adsorbents as CO2 adsorbers and how N2 and pore size distribution influence CO2 adsorption. The active carbon adsorbent used comes from jengkol peel which is carbonized via the pyrolysis method. Adsorbents are made by varying the type of activating material (KOH, Urea, and KOH+urea) and activation temperature (600℃, 700℃, and 800℃). The active ingredient KOH+urea has better absorption capacity than other variations, but not too high. N2 gas does not really affect the CO2 adsorption process because it has a low N2 adsorption isotherm, so it is not worrying if the CO2 adsorption process also contains N2 in the air. Based on measurements with Belsorp-Max II, the data obtained is only specific surface area data, this is due to the small surface pores of the adsorbent. The temperature of 800℃ has a better specific surface area than other variations, this is also by the higher CO2 adsorption capacity. So it is concluded that the pore surface area influences the ability to absorb CO2. Based on the data obtained, jengkol peel charcoal is not suitable as a CO2 adsorbent because it has a low pore surface area and adsorption isotherm

Abstract

The manufacturing of Unmanned Aerial Vehicles (UAV) requires a design process that involves the design of aircraft’s components such as fuselage, wing, horizontal stabilizer, vertical stabilizer, ailerons, elevators, tail, and wing. The process takes a long time. Therefore, the distribution of structural works based on their characteristics and classifications by considering their design attributes and manufacturing processes is required. This research aims to find the optimal time and critical path of the assembly process of an UAV based on product work breakdown structure (PWBS) and critical path method (CPM). The result reveals that the optimal assembly time is 139 minutes. Finally, the application of product-oriented structural work distribution and the optimization of the assembly activities involved in the critical path successfully minimize the duration of the assembly process.
