Abstract

Ulujami Sub-district is one of the sub-districts in Pemalang Regency, Central Java. Ulujami Sub-district is around 2305 ha, covering 18 urban villages. The 18 villages are: Ambowetan, Blendung, Botekan, Bumirejo, Kaliprau, Kertosari, Ketapang, Limbangan, Mojo, Padek, Pagergunung, Pamutih, Pesantren, Rowosari, Samong, Sukorejo, Tasikrejo, Wiyorowetan. It’s a densely populated region. Some urban villages are located at the northern coastline of Java and along rivers, and are often hit by tidal floods. Therefore, a study on the effect of tidal water on the quality of well water at the coastline of Pemalang Regency, specifically Ulujami Sub-district, is necessary. The data required by the present study were administrative map and well water quality parameters from the Decision of the Minister of Health No.416/MenKes/Per/XI/2010. The instruments were GPS, stationary, and Water Quality Checker. The well water sampling used stratified random sampling technique. The analysis included quality test of well water in tidal flood areas. The research result showed that in general the well water quality in Ulujami Sub-district was unqualified for daily needs. However, some locations near the coast showed high salt content, so well water wasn’t recommended for drinking, especially water from dug well. The well condition in Ulujami Sub-district is generally not fit for use. Of 36 tested well water in Ulujami Sub- district, 88.89% of the wells had odorless water, and 11.11% had slightly odored water, 11.1% had salty water, 3.89% had slightly salty water, and 75% had non-salty water, 44.44% had clear water, 33.33% had slightly cloudy water, and 22.22% had cloudy water.

Abstract

Effectiveness is the goal in a system. To achieve this, it is necessary to carry out continuous development. Likewise, what is done in small industries in Pasangsari village, Windusari district, Magelang regency. The abundance of cassava in this area makes the community required to innovate in terms of cassava processing. One of the speakers processes cassava into rengginang. By processing it into rengginang, the cassava has a longer life because it is stored in a dry state. In addition, selling cassava that has been processed into rengginang has greater added value in terms of selling price. The problem in this study is the effectiveness of the tool because it still uses conventional methods where the drying process is still dependent on sunlight, while erratic weather conditions become a barrier in the drying process. The purpose of this research is to design a tool with a temperature control system so that the effectiveness of the tool manufacturing process can be achieved. Keywords: automatic drying machine, design, production, cassava, rational methods

Abstract

Sungai Tenggang merupakan bagian dari sistem drainase Kota Semarang. Sungai Tenggang tidak terlepas dari masalah banjir. Masalah utama penyebab luapan Kali Tenggang dan banjir di Kota Semarang adalah curah hujan yang cukup tinggi di Wilayah Kota Semarang dan elevasi muka air pada penampang sungai meningkat. Dalam hal ini akan dilakukan analisis kenaikan muka air banjir sungai dengan menggunakan software HEC-RAS 4.1.0. Metode Nakayasu HSS digunakan untuk menghitung debit banjir yang dirancang, dan memberikan hubungan antara parameter aliran dan waktu. Parameter ini bisa berupa kedalaman aliran atau debit aliran. Dalam analisis hidrolik, program HEC-RAS 4.1.0 digunakan untuk memodelkan penampang melintang sungai. Hasil perhitungan debit banjir rencana Sungai Tenggang menggunakan metode HSS Nakayasu menghasilkan debit banjir maksimum sebesar 303.715 m3/detik periode 2 tahun; 356.318 m3/detik, untuk jangka waktu 5 tahun; 386.651 m3/detik; 421.348 m3/detik, selama 10 tahun; 445.047 m3/detik, selama 25 tahun; dan 467.190 m3/detik periode 100 tahun. Berdasarkan hasil pemodelan banjir dengan menggunakan software HEC-RAS, terdapat debit air yang tinggi akibat luapan dari Kali Tenggang Semarang. Di STA 1800 terjadi elevasi muka air yang cukup tinggi yaitu 4,5 m, dan untuk STA 2000 terjadi elevasi muka air yang sangat tinggi yaitu 5 m.
