Abstract

Indartono, in this paper explain that soybean seed quality decline if easy packaging and storage techniques are not good. This research aims to study the technique of packing and room temperature on soybean seed quality during the four months of storage. Research conducted at the Laboratory of Postharvest and Alsintan, BPTP Central Java, with a Completely Randomized Design 3 (three) factors and two replications. The first factor varieties (Burangrang, Willis, and Baluran), the second factor technique packaging (vacuum and without vacuum), and the third factor storage temperature (27-29 ° C and 6 ° C). During the four storage observed changes in water content, shrinkage and the weight of soybean seed germination. The results showed that the shrinkage weight, water content and temperature of storage space does not give real effect to the power of germination for 4 four months of storage, and storage techniques vacuum (vacuum) to give an average power of germination is higher than without vacuum treatment, but a statistically not significantly different from other treatments by Duncan's test 95% confidence level for all varieties Key words: soybean, room temperature storage, packaging techniques, the germinated

Abstract

Indartono, in paper use of alternative fuel gas for a motor vehicle fuel oil explain that in many ways energy efficiency can also be more than just preservation. Energy efficiency is an attempt to reduce the use of petroleum materials and the selection of alternative fuels. Improved energy efficiency is also an environmental demands, because it can reduce air pollution, acid rain control the incidence and protect the earth from global warming, which may occur due to buildup of carbon dioxide in the atmosphere. One of the alternative fuel is CNG. In motor vehicles, CNG usage advantages include lower price, the exhaust gas is cleaner burning results and the potential source is still very large. Keywords: energy efficiency, fuel, CNG

Abstract

Industri Ukir Tembaga dan Kuningan Mbed Doer Anather Craft merupakan salah satu industri tembaga dan kuningan yang masih eksis di Tumang Cepogo Boyolali. Keberadaan industri ukir tembaga dan kuningan di Kelurahan Tumang Cepogo memberikan potensi yang besar terutama di bidang ekonomi, sosial, pendidikan dan lapangan kerja. Industri ukir kuningan dan tembaga juga memberikan dukungan pada wisata alam dan agro di daerah lereng gunung Merapi dan Merbabu khususnya wisata alam pegunungan Selo. Pengerjaan produk ukir dengan teknik pemanasan, pembentukan dan penyelesaian akhir untuk desain rumit dan ukuran relative besar masih menjadi kendala. Tujuan kegiatan pengabdian adalah kajian dan analisa spray gun untuk proses pelapisan produk ukir tembaga dan sejenisnya. Proses pelapisan logam perlu perlakuan awal yakni dengan pembersihan. Peralatan spray gun pada prinsipnya terdiri dari injektor (nozzle), selang dan kompresor. Jarak semprot atau nozzle dengan permukaan yang akan dicat 100 – 200 mm. Jarak semprot itu prinsipnya tegak lurus. Beberapa cacat pelapisan dengan spry gun meliputi orange peel, runs, pinholing, peeling, polishing marks, solvent pop, mottling, matting, lifting, cracking, colour mismatch, fish eyes, dan srinkage. Peningkatan kualitas pelapisan dengan spry gun dapat dilakukan dengan mekanisme pemanasan atau termal
