Abstract

The degradation of nature has potential to weaken the harmony between humans and their environment in a number of subak. Subak culture is only effective at the level of the superstructure, but the level of implementation is that subak have begun to be degraded due to land conversion, transfer of professions, poor economies, and young people who do not want to continue subak tradition. The purpose of this research is to see the existence of subak civilization then creates the policy strategy to develop Subak’s role as an ecological civilization tourism destination. The effectiveness method was used to see the existence of subak and AWOT Method as subak developing strategy to an ecoculture-tourism. Based on the results of effectiveness analysis and AWOT, it shows that subak culture as Bali civilization at the superstructure level is still exists and strong. However, at implementation level, there had been a weakening especially in urban areas. The implementation and preservation of the Sarbagita community based on the three components study was quite effective even for the superstructure component into a very effective category with an effectiveness value of 83.84%. So the components of the superstructure need to be maintained as a fortress of civilization in Sarbagita. However, the components of the social structure and infrastructure had quite low values, which are 59.55 percent and 50.32 percent respectively, which was included in the effective category but located in critical value. So it needs to improve level of social structure and infrastructure so that the three components of the subak civilization run effectively.Degradasi alam berpotensi melemahkan harmonisasi antara manusia dan lingkungannya di sejumlah subak. Budaya subak hanya efektif pada tingkat suprastruktur, tetapi dalam implementasinya subak telah mulai terdegradasi karena konversi lahan, pengalihan profesi, ekonomi miskin, dan kaum muda yang tidak ingin melanjutkannya. Tujuan penelitian ini adalah untuk melihat keberadaan peradaban subak, kemudian strategi kebijakan dalam mengembangkan peran subak sebagai tujuan wisata peradaban ekologis. Metode efektivitas digunakan untuk melihat keberadaan subak dan metode AWOT sebagai strategi pengembangan subak untuk wisata peradaban ekologi. Berdasarkan hasil analisis efektifitas dan AWOT menunjukkan bahwa budaya subak sebagai peradaban Bali di tingkat suprastruktur masih ada dan kuat. Namun, pada level implementasi telah terjadi pelemahan, terutama di daerah perkotaan. Pelaksanaan dan pelestarian masyarakat Sarbagita berdasarkan tiga komponen (sebutkan komponennya) yang diteliti efektif bahkan untuk komponen superstruktur masuk kedalam kategori sangat efektif dengan nilai efektivitas sebesar 83.84%. Sehingga komponen superstruktur perlu dipertahankan sebagai benteng peradaban di Sarbagita. Namun untuk komponen struktur sosial dan infrastruktur mempunyai nilai cukup rendah yaitu berturut-turut 59.55 persen dan 50.32 persen yang termasuk dalam kategori efektif tetapi berada pada titik kritis. Sehingga perlu dilakukan perbaikan pada tataran struktur sosial dan infrastruktur agar ketiga komponen peradaban subak berjalan efektif.

Abstract

Gamma irradiation to induce mutation in plant has been used intensively since several decades ago.  On maize, 275 Gy gamma irradiation have been known to increase genetic variability indicated by their morphological variation.  Identification on genetic changes by molecular technique is important to answer whether there is mutation happening on DNA level of the plants.   The objective of this research was to identify RAPD marker polymorphism on gamma irradiation mutants compared to their parents.  The initial step of the research was to select random primers could positively amplify the maize DNA.  The result showed that selection on 60 random primers yielded 15 primers that positively amplified the maize DNA.  Amplification on both mutants and their parents by those 15 selected primers indicated that only 5 primers yielding polymorphism between mutants and their parents.  Polymorphisms on mutant G1, G3 and G6 were detected on one locus, meanwhile on mutant G7, G8 and G9 were on two loci.

Abstract

Jakarta merupakan ibukota Indonesia dan sebagai kota besar dengan jumlah penduduk 9.588.198 orang pada tahun 2010 (BPS, Juli, 2010). Saat ini Jakarta perlu air bersih sebanyak 524.953.840 m3 untuk domestik dan non domestik 212.606.350 m3 atau total 737.560.145,20 m3. Kapasitas produksi dari PAM Jaya pada tahun 2009 sekitar 509.431.934 m3/tahun. PAM Jaya saat ini hanya mampu memenuhi sekitar 69,07% dari total kebutuhan DKI Jakarta. Untuk memenuhi air bersih, Jakarta membutuhkan air tambahan dari provinsi lain dan 80% supply untuk Jakarta berasal dari Citarum (Jawa Barat) dan Cisadane (Tangerang-Banten) dan lainnya. Penelitian ini dilakukan selama 13 bulan mulai Juni 2010 sampai Juli 2011. Penelitian ini bertujuan untuk mengidentifikasi penyediaan (supply) dan permintaan air bersih serta mengidentifikasi kebijakan keluar tentang pemenuhan air bersih lintas wilayah atau kabupaten dan membuat modelpemenuhan kebutuhan air antar wilayah secara berkelanjutan. Metodologi analisisnya menggunakan Multi Scalling Dimensional (MDS) untuk analisis keberlanjutan air bersih untuk pemenuhan di Jakarta. Pemerintah memiliki peran sentral dalam memenuhi kebutuhan air bersih, pemenuhan air bersih perlu memahami lebih lanjut tentang supply dan permintaan air. Masalah banjir masih sering terjadi. Di dalam pemenuhan air bersih secara berkelanjutan, nilai dimensi ekonomi (69,17) dimensi hukum dan kelembagaan (68,24), dimensi prasarana dan tecnology (61,45), tetapi dimensi ecology tidak berkelanjutan dengan skor (48,75 ). kata kunci: air bersih, lintas wilayah, pemenuhan,keberlanjutan. AbstractJakarta is the capital of Indonesia and as a big city with 9.588.198 people in 2010 (BPS, July, 2010). Jakarta needs clean water 524.953.840 for domestic and non domestic 212.606.350 m3 or the total 737.560.145,20 m3. PAM Jaya production capacity in 2009 is about 509.431.934 m3/year. PAM Jaya capacity is about 69,07% of the total needs DKI Jakarta. To fulfil the clean water, Jakarta needs water supply from the other provinces and 80% water supply for Jakarta is from Citarum (West Java) and Cisadane (Tangerang-Banten) and others. A research has been done within 13 months started from 2010 June to 2011 July. The research is aimed to identify the supply and demand of clean water and identify the exiting policy about fulfilment the clean water cross boundaries or district and to make the model of fulfilment the clean water cross boundaries with sustainable. The methodology analysis is Multi Dimensional Scalling (MDS) methodology to analysis sustainablity of fulfilment clean water of Jakarta. The goverment has a central role to fulfill the needs of clean water, fulfilment clean water needs to understand more about supply and demand of water. The problem is the flood has often occured. The sustainable of fulfilment clean water is economi dimensional (69,17) dimensional of law and institution (68,24), dimensional of infrastructur and tecnology (61,45), but dimensional of ecology is not sustainable with the score (48,75). key words: Clean Water, Cross Boundaries, Fulfilment, Sustainable.
