Abstract

Jember has 16.882 ha of coffee plantation, which  5.601,31 ha of them are smallholder coffee. Smallholder coffee is often identified has  low productivity and quality. This research wanted to know: (1)the advantage of smallholder coffee at District of Jember; (2) how to increase the advantage. Research was done on May – August 2012 (harvest periode) at Sub District of Silo, Sumberjambe, Ledokombo and Panti with 98 respondens which were choosen by  stratified random sampling methode.  The advantage was measured by  DRCR dan PCR, in order to increase the advantage using the result of Cobb-Douglas model of multiple regression analize on production function.  The  result show  that:  (1) there are two methode of post-harvest processing of coffee, they are wet process and dry process methode;(2) smallholder coffee at Jember has competitif and comparative advantage (PCR wet process methode is 0,3679 and dry process methode is 0,4261). (3) Balance fertilizing could increase  the advantage, but just comparative advantage (DRCR decrease to  0,4907 on wet process methode and 0,3566 on dry process methode), on the other side competitive advantage was a little decrease (PCR wet process methode is 0,5056  and  0,5089 on dry process methode).  Further more, balance fertilizing could increase the profit from IDR 17.804.906/ha/year to                IDR 21.103.109/ha/year on wet process methode and from IDR 8.965.371/ha/year to            IDR 17.112.813/ha/year on dry process methode.

Abstract

Shallow groundwater in urban areas today is no longer fully utilized directly for domestic human needs. Some of the factors that cause, among others, due to pollution of springs by household waste, too much groundwater production resulting in the reduced amount of ground water. Finally the water function as a solvent and the neutralizer of the pollutant decreases as the water becomes less clear. By utilizing coconut shells as activated carbon mixed with silica sand, zeolite, and manganesee in this research can reduce turbidity, TDS and ground water PH so that the water produced can meet clean water standards according to PERMENKES/RI No.416/IX/1990. The objective of this study was to find an effective mixture composition to purify water using 5 different mixing compositions and it can be concluded in this study that coconut shells used as activated carbon amount to 35% of total media composition. So the most optimal composition to produce water with good quality of 35% active carbon, 25% silica sand, manganese 20%, 20% zeolite. In this composition also, Mangan (Mn) and Iron (Fe) have decreased and meet the quality standard of raw water quality as required by PERMENKES quality standard of Class B water quality.

Abstract

The main objective of the Technology for the Society (IbM) is aimed at addressing the main problems faced by approximately 200 urban poor, namely: (1) The location of the residence located on the edge of the city with a distance society of about 10 km from urban areas. (2) Low economic level or low income about Rp.600.000 / month so it can not meet the basic needs and lift the economy of the surrounding community. The specific target in this IbM program is to apply Batako engine utilization technology to improve the quality and quantity of local Batako production of marginalized urban communities which originally produced only Batako blocks of about 200 seeds to 1000 seeds per day and increased concrete compressive strength. from 175 Kg / cm2 to 225 Kg / cm2, thereby increasing employment for the surrounding communities and increasing the income of business actors and partner workers. The method of implementation to solve the problems of the program partners of IbM is to increase the added value of community income through the utilization of Batako chili type which includes the stages: (a) Thesocialization of Batako IbM program; (b) Preparing social prerequisites, such as strengthening rural community groups, groups and forums as a medium to meet and solve problems faced by farmers or the poor; (c) Implementation of Batako IbM program, supported by related institutions (Dinas Cipta Karya Kabupaten Lumajang and University (Faculty of Engineering, Muhammadiyah University of Jember), and (d) Monitoring, evaluation and reporting.

Abstract

Terjadinya bencana banjir di Kecamatan Panti Kabupaten Jember  agak sulit diprediksikan sehingga akan kesulitan melakukan antisipasi. Pada tahun 2009 sekitar 8.936 hektare hutan gundul, maka tatkala turun hujan deras mudah menimbulkan banjir dan longsor, air bah yang datang berwarna coklat karena bercampur lumpur akibat longsorang yang terjadi secara terus menerus. Menurut catatan Satkorlak Bencana Kabupaten Jember, kejadian banjir tahun 2009 telah menimbulkan banyak korban diantaranya 250 orang meninggal, 120 orang tidak ditemukan atau hilang dan sekitar  86 hewan piaran hilang dan mati. Bencana banjir telah menimbulkan trauma bagi masyarakat, sehingga pada saat hujan terjadi dengan intensitas dan durasi yang tinggi timbul was-was dari masyarakat dan kekhawatiran peristiwa terjadinya bencana banjir dan longsor  terulang lagi.  Akhirnya secara psikologis masyarakat tidak dapat menjalani kehidupan secara tenang dan tentram.  Maka langkah antisipasi perlu dilakukan, yaitu dengan melakukan menciptakan sebuah teknologi sensor untuk peringatan dini banjir, sehingga kejadian bencana dapat diketahui  beberapa jam sebelum  terjadi dan kerugian akibat bencana banjir juga dapat diminimalisir. Bahkan dengan didukung ketersediaan sistim infomasi, sensor ini akan memberitahukan kepada masyarakat secara otomatis berapa lama lagi banjir akan terjadi termasuk besaran debit puncak yang akan terjadi termasuk tingkatan bencana yang akan terjadi. Adapun target khusus penelitian ini adalah diperolehnya sebuah alat sensor banjir yang integrasi dengan stasiun pengukur hujan sebagai sistim informasi peringatan dini banjir. Tahapan kegiatannya adalah pengumpulan peta administrasi wilayah, survey posisi dan tata letak stasiun hujan yang ada layout, perancangan sensor stasiun hujan, kalibrasi sensor,  integrasi sistim informasi dan pemasangan sensor di lokasi penelitian. Sistim modifikasi stasiun hujan otomatis telah dibuat sebanyak 3 buah dan telah berhasil diintegrasikan dengan sistim informasi bencana banjir telah dibuat. Setelah dilakukan beberapa kali test lapangan diperoleh hasil bahwa sensor dapat merekam data tinggi hujan sampai dengan 200 mm dengan tingkat kesalahan kurang dari 10 % serta dapat menyajikan sistim informasi bencana yang terdiri dari debit banjir, tinggi air banjir dan status bencana.Kata Kunci : Bena, Sensor, Banjir, Stasiun, Hujan.

Abstract

Drainase adalah salah satu fasilitas yang digunakan untuk mengalirkan air agar tidak mengakibatkan genangan yang dapat mengganggu aktifitas penduduk, perekonomian. Di kawasan pemukiman kampus Kecamatan Sumbersari kabupaten Jember terdapat permasalahan banjir yang ditimbulkan oleh curah hujan yang tinggi serta perubahan peruntukan lahan cukup signifikan. Perubahan peruntukan lahan yang semula sawah atau lahan kosong menjadi permukiman. Adanya perubahan tata guna lahan tersebut mengakibatkan limpasan (runoff) akan bertambah besar. Disamping itu adanya pengendapan sedimen sehingga mengurangi luas penampang basah, akibatnya dimensi saluran drainase yang ada tidak dapat menampung debit banjir maksimum. Untuk mengantisipasi masalah-masalah yang terjadi karena, maka perlu suatu perencanaan sumur resapan. Setelah dilakukan analisa dan kajian diperoleh beberapa kesimpulan diantaranya : pada perhitungan debit banjir rencana, hampir semua dimensi saluran drainase existing sudah tidak dapat melewatkan debit banjir rencana kecuali pada saluran Jalan Kalimantan F1, Jalam Kalimantan F2 dan Jalan Mastrip H1. Jika dilakukan peresapan air, maka diperlukan sumur resapan pada masing-masing ruas dengan total sebanyak 4146 Buah. Kata Kunci : Drainase, sumur, resapan, banjir

Abstract

Water balance can be used as a guide to the presence or absence of water in an area. In the concept of the hydrological cycle that the amount of water in a certain area on the surface of the earth is influenced by the amount of water entering (input) and out (put) in a certain period. Balance input and water output somewhere known as water balance. Since water is dynamic, the water balance value changes from time to time so that somewhere there may be surplus or deficit. If the shortage and excess water is in extreme circumstances can certainly cause disasters, such as floods or drought. The disaster can be prevented or mitigated if good management of the land and the environment is carried out. The water balance is a water balance for agricultural land use in general. This balance sheet is useful in considering the suitability of agricultural land, arranging planting and harvesting schedules, arranging irrigation water supply in the right amount and time. It cannot be denied that some areas of Java and Madura have experienced water shortages, of all the water earth 97.5% is salt water, fresh water is 2.5%.This not entirely surface water and ground water. In Kabupaten Jember, especially in the area of underground water sampling (ABT) conducted by drilling wells in community development projects from the results of this study is expected to help and provide solutions to communities in the study area in the form of water buildings for storage of agricultural water reserves.Keywords:Reviewof Craft Balance
