Abstract

ABSTRACT The Government of Republic Indonesia had positively responded the emerging of new paradigm on irrigation management. Government Act No. 7/2004 on water resources as well as tile new Government Regulation No. 20/2006 on irrigation state about concept on good governance in management of water resources as well as irrigation management. One of implementation of the concept is application of irrigation management asset. The Department of Agricultural Engineering, Gadjah Mada University. Yogyakarta had been developed the concept of irrigation asset management plan since 1995. This paper aims to discuss the concept development and its implementation in several irrigation systems in Java. Even though some constraints were also found, in some extend the implementation of irrigation asset management plan could help the management of irrigation system in providing several information in transparent way to all stakeholder especially farmers. Diterima: 15 Pebruari 2007; Disetujui: 4 Maret 2007

Abstract

Pengasapan karet RSS adalah metode pengawetan dan pengeringan karet lembaranmenggunakan asap kayu bakar agar jamur tidak tumbuh saat penyimpanan. Pada umumnya pengasapan karet RSS konvensional membutuhkan waktu 5-6 hari dan konsumsi kayu asap sebanyak 4 m3 per ton karet kering. Selain itu mutu RSS juga ditentukan oleh pengontrolan yang rutin mengenai bahan bakar kayu dan suhu ruang pengasapan. Penelitian ini berupaya meningkatkan mutu karet RSS dan efisiensi energi proses pengasapan karet RSS dengan menerapkan sistem kendali otomatis berbasis mikrokontroller yang dapat mengatur konsentrasi asap dan suhu.  Sistem kendali ini merupakan sistem yang akan mengatur suhu dan kepekatan asap pada setiap tingkatan suhu. Tujuan penelitian ini adalah untuk melakukan perancangan dan pengujian pengendalian suhu dan konsentrasi ruang asap karet RSS menggunakan mikrokontroller. Prosedur penelitian ini mencakup; 1) Disain dan Konstruksi, 2) Merancang perangkat keras  kendali, 3) Merancang perangkat lunak, 4) Kalibrasi Sensor LM 35 dan 5) Pengujian sistem kendali pada ruang pengasap. Hasil pengujian sistem kendali suhu dan konsentrasi asap adalah proses pengasapan karet RSS terbagi pada 4 tingkatan suhu yaitu suhu 400C-450C selama 12 jam, suhu 450C-500C selama 12 jam, suhu 500C-550C selama 12 jam, dan suhu 550C-600C selama 24 jam. Keberhasilan pengujian ini dicapai selama 60 jam atau 2,5 hari. Mutu karet RSS berwarna coklat transparan, tidak timbul gelembung dan lembaran tidak tambah panjang atau putus. Karet RSS menjadi dominan mutu RSS 1 setelah terjadi penguapan air sebesar 35,78%. Adapun panjang karet RSS berkurang sebesar 3,81%, lebar berkurang sebesar 8,95% dan ketebalan bertambah sebesar 4,36%. Penggunaan kayu bahan bakar asap sekitar 2 m3 dengan kapasitas karet RSS 1.000 Kg.

Abstract

Managing irrigation water is not only distribute irrigation water .to the assigned field, but it is also include arranging the cropping pattern and scheduling in order to fit it to the availability of irrigation water. Cropping pattern and scheduling plan is the important things because each crop has its characteristics in water consumptions and on the other hand there is a limited water resources. There are three important factors in determining of cropping pattern and scheduling: (i) farmers need, (ii) service target and (iii) the ability of irrigation scheme. in the era of Government Regulation No 77/01, farmers participation in operation and maintenance (O&M) of irrigation scheme is an important things. The consequences is the managers of irrigation scheme have to negotiate these cropping pattern and scheduling plan as well as its water allocation to the farmers. The aim of this study is to prepare the tool to make easier during negotiation for determining the cropping pattern and scheduling. This tool is a computer program of information systems used for O&M of an irrigation scheme, and it is based on the availability of irrigation water, irrigation scheme performance, crop characteristics as well as its water consumption, market driven as well as the income offarmers.
