Abstract

The objectives of this study are to analyse fish catch characteristics of arad and dogol (both are likes mini trawl), which categorized as "illegal" fishing gears. Study was conducted at northern coastal of West Java province. Results of this study showed that species number and total catch weight varied among fishing gear. Based on the species number, arad which operated in Eretan Kulon could captured highest number compare to other fishing gears. On the other hand, based on the catch weight, dogol which operated in Karangreja captured highest catch weight compare to other fishing geras. The diversity analyses of catch species showed that all of fishing gears have a diversity index > 0.1. This result indicated that all of "illegal" fishing gears categorized as low species selectivity.

Abstract

Kearifan lokal merupakan kebijakan manusia dan komunitas dengan bersandar padafilosofi, nilai-nilai, etika, cara, dan perilaku yang melembaga secara tradisional untukmengelola sumber daya alam, sumber daya manusia dan sumber dayabudaya secaraberkelanjutan. Salah satu kearifan lokal dalam masyarakat Bali adalah adanya persepsitentang kawasan-kawasan suci. Dalam masyarakat Bali terdapat berbagai perangkatkepercayaan tradisional yang merupakan bagian yang terintegrasi dari sistem kepercayaanAgama Hindu yang terbukti memberikan nilai positif bagi kelestarian dan pelestarianlingkungan.Berdasarkan pandangan Hindu sumber-sumber air atau tempat yang banyak menampungair dianggap sebagai salah satu tempat suci. Air yang murni (suci) baik dari kelembutan (mataair), danau, campuhan (pertemuan dua buah sungai atau anak sungai) loloan (pertemuansungai dengan laut) mempunyai kekuatan yang menyucikan.Air merupakan salah satu unsur penting dalam upacara keagamaan Hindu. Untukmembuat tirta, air biasanya diambil dari mata air tertentu. Pada saat-saat tertentu (misalnyaHari Raya Nyepi) masyarakat Hindu melakukan upacara melasti ke sumber-sumber air,seperti danau, campuhan, atau ke laut.Air sungai atau mata air dalam fungsinya sebagai tirta, dalam prosesi upacara dipakaiuntuk memerciki bagian kepala, tubuh, dan kemudian diminum. Karena itu, air sungai ataumata air harus tetap bersih dan tidak tercemar. Karena fungsinya tersebut masyarakat selaluberusaha untuk menjaga agar kondisi atau kualitas air tetap terjaga. Jadi secara sadar atau puntidak mereka telah melakukan penjagaan dan konservasi terhadap lingkungan mata air.Bagi krama subak air sangat bermakna dalam kehidupan mereka . Secara teknis airmerupakan sumber daya yang sangat penting bagi mereka agar dapat melaksanakan aktivitaskehidupan bertani. Secara religius mata air diyakini sebagai sumber kesejahteraan mereka.Hal ini dapat dilihat melalui aktivitas-aktivitas keagamaan yang dilakukan petani selaluberorientasi pada pura-pura yang terletak pada sumber-sumber air utama, yaitu Pura UlunSuwi dan Pura Ulun Danu.

Abstract

Shifting cultivation is the oldest agricultural system widely practiced until now especially in tropical areas. Since this system requires relatively extensive use of land and uses slush and burn technique it is often labeled as a main cause of deforestation and land degradation. Each household of farmers needs about 1 – 5 hectares of land for shifting cultivation. On the other hand a lot of researchers have different opinions. They believed that shifting cultivation system has positive influenced on environment because it can increase biological diversity. Many studies show that the system does not caused permanent land degradation as long as the fallow period is not too short. Many scientists believe that if the system causes environment degradation then a lot of forested areas in Indonesia will have turned into desert now. Shifting cultivation practiced by Dayak communities in Kalimantan does not cause serious deforestation.

Abstract

TThe aimed of this study was to know agronomic characters performance of SMB-5 line mainly yield potential, compared to another local varieties in an arid area. The study was conducted at Sumber Klampok Buleleng in 2007. Randomized Block Design was used, seven varieties i.e. : SMB-5 line (Bt), Seraya (Sr), Cicih Tombong (Ct), Pulut Putih (Pp), Lombok Putih (Lp), Tongtongan Tianyar (Tt), and Ketokong (Kt) as a treatment with three replications. Ninety plants were taken as a random sampling from every genotype. Quantitative characters of SMB-5 line and another varieties tested showed a significant different for more variables except for maximum leaf number, time of tasseling, time of silking, number of productive pods and harvest index. SMB-5 line and another varieties tested was different in genetics showed by a high heritability (h2 > 0.50), and some others showed a main heritability (h2 >0.20). SMB-5 give the highest yield (4.02 ton/ha) which are significant different from another local varieties. SMB-5 lines have a good adaptation potential to an arid area.
