Abstract

Wingko babat merupakan makanan oleh-oleh khas Kota Semarang yang banyak diminati oleh para wisatawan. Proses pembuatan wingko babat meliputi beberapa tahap yaitu tahap pencampuran bahan baku, pencetakan, pemasakan, pendinginan dan pengemasan. Namunpada proses pemasakan, bahan yang dimasak tidak bisa merata. Hal ini disebabkan distribusi api atau panas tidak merata sehingga produk yang dihasilkan terkadang ada yang gosong. Kuantitas produk atau jumlah bahan yang dimasak tidak bisa maksimal karena proses pemasakan lama. Akibatnyasulit memenuhi permintaan pasar. Untuk mengatasi permasalahan ini perlu dilakukan perbaikan sistem pemasakan bahan wingko babatdengan cara mendesain ulang peralatan masaknya yaitu dengan rancang bangun alat masak bahan wingko babat.Alat ini dinamakan modified oven. Alat ini terdiri dari lima bagian utama yaitu (1) saluran pipa, (2) modified oven, (3)lubangtempat keluarnya api, (4) lubang sirkulasi udara, dan (5) penyangga. Hasil aplikasi alat ini menunjukkan peningkatan kuantitas dan kualitas produk. Kapasitas produksi meningkat 75% per harinya.Penggunaan bahan bakar untuk sekali masak menurun 50%. Omset produksi naik menjadi hampir 75% dan keuntungan UKM meningkat 2 kali lipat. Hasil pemasakan dapat seragam sehingga produk wingko yang dihasilkan tidak sampai gosong. Tekstur produk lembut dan proses pemasakan menjadi lebih cepat. Kualitas produk wingko menjadi lebih terjaga dan dapat memenuhi permintaan pasar khususnya pada musim wisatawan.

Abstract

Small electroplating industry is a small industry that is widely available in the city of Semarang. The mainprocesses in the electroplating industry are located in the coating process. This process occurs in theelectroplating bath. The quality of the metal coating is highly dependent on the quality of the chemicalsolution contained in the electroplating bath. If the chemical solution has good quality, such as the solutionwas clear, there are no impurities, the quality of the coating is also good. If the quality of the chemicalsolution is not good, then the results of the coating are also inferior such as there are bubbles in the layer, orthere is dirt on the die so that the coating process must be repeated. This will add to the cost of productionand a coating time so that increases operational costs. To solve this problem we need a system that canproduce a chemical solution that has good quality, clear, and there are no impurities. This system is calledthe filter electroplating. Results of electroplating filter application showed to increase the quantity andquality of production. The production capacity increased by 30% per day. The production turnover up 35%and profits increased by 45%. The chemical solution becomes clear and does not contain impurities so thatthe coating results becomes good.

Abstract

Biodiesel has become more attractive recently because of its environmental benefits and the fact that it is made from renewable resources. Biodiesel can replace diesel oil without requiring modifications to the engine and advantageously produces cleaner emissions. Productions of biodiesel by various process methods, i.e. homogeneous, heterogeneous, and enzyme catalysts, have advantages and disadvantages. Advanced methods, such as supercritical, microwave, and ultrasonic, still leave the problem despite the high yield of biodiesel produced. Utilizing of fixed bed catalytic reactor in a continuous process can produce biodiesel with a yield of higher than 90%. The newly developed plasma technology can produce biodiesel in a very short time (120 s) with mild operating conditions. This paper reviews briefly the literatures on transesterification reaction using homogeneous, heterogeneous, and enzyme catalysts as well as advanced methods (supercritical, microwave, ultrasonic, and plasma technology).
