Abstract

Vegetation diversity and intensity of plant pests and diseases in two polyculture systems in Tanggamus District. The vegetable crop management cannot be separated from infestation of plant pest and disease which influences the quality and quantity of crop yield. The pest organism development is influenced by agroecosystem. The objective of this research was to analyze vegetation diversity and intensity of pest and disease in Tanggamus District. Methods used in this research were analysis of vegetation diversity based on Shannon index, percentage of pests damage and diseases incidence. The results showed that the vegetation diversity in polyculture of agriculture typology were 11 plant species with diversity index of 0.64; while in polyculture of agroforestry typology there were 11 plant species with diversity index of 0.74 and both of these indices were less than 1 (H? < 1). The percentage of pests damage in the polyculture of agriculture larger than polyculture of agroforestry typology ranging from 7.20% to 81.67% and 3.04% to 26.67% respectively. While the incidence of disease in polyculture of agriculture ranging from 0.65% up to 100% and polyculture of agroforestry typology 0.65% up to 68.00%.

Abstract. Subak as Bali Civilization Fortress. 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. Keywords: AWOT, subak civilization, effectiveness Abstrak. 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. Kata Kunci: AWOT, peradaban subak, efektivitas
