Studi Etnoekologi Masyarakat Dani-Baliem Dan Perubahan Lingkungan Dilembah Baliem, Jayawijaya, Irian Jaya*[ethnoecological Study of the Dani-Baliem Society and the Environment Changes in Baliem Valley, Jaya Wijaya, Irian Jaya]

The objective of the ethnoecology study of the Dani-Baliem society is to know the relationship between Dani-Baliem society and their environment.This study covers the perception and traditional management system of environment by the Dani-Baliem society, and also the impact of their activities to the environment change in Baliem Valley. This study is expected to determine the change of plant diversty, which happened, and to reconstruct this change from pre-historic era to the present time.The methods used in this study based on anthropological, ecological, paleoecological and bibliography study.The result showed the ecosystem change in the Baliem valley since 26.000 BP.It was indicated by Carbon content as a result of fired activities in the base of valley sedimentation.Since 7000 years ago, the impact of human activities in the Baliem valley area is significant. It is indicated by organic material sedimentation.This environment change continue untill now and relate to the intensity of human activities intervention. These human activities cause many enironment units which has physical and biological characteristics. By using floristic analysis in each environment unit, it can be seen the change of plant diversity composition in this area

Pola Arus Di Perairan Paciran Jawa Timur Pada Musim Peralihan Awal

Wilayah Perairan Paciran, Jawa Timur merupakan perairan dengan aktivitaswisata bahari, pelabuhan, permukiman dan lain-lain.Kondisi tersebut dapat menimbulkan dampak-dampak negatif seperti erosi, tanah yang timbul akibat sedimentasi dan lain-lain.Pengetahuan akanpemahaman gambaran mengenai kondisi hidro-oseanografi sangat penting sebagai langkah untuk pengelolaan dan perlindungan wilayah pesisir dan laut. Tujuan dari penelitian ini yaitu untuk mengetahui pola arus laut yang ada di Perairan Paciran Jawa Timur pada musim peralihan awal (Maret sampai April).Penelitian ini menggunakan data primer berupa data arus dan data pasang surut, sedangkan data sekunder berupa peta batimetri. Simulasi model diolah menggunakan software ArcGIS 9.3 dan SMS 8.1 , didukung dengan pengolahan data menggunakan CD-Oceanography dan Mike 21. Hasil simulasi model menunjukkan bahwa pola arus di Perairan Paciran Jawa Timur merupakan arus non pasut, di tunjukkan oleh hasil pengolahan dalam bentuk stick diagram, scatter dan current rose yang menunjukkan pergerakan arus cenderung tidak teratur. Pada saat surut menuju pasang kecepatan maksimum berkisar 0,2851 meter/sec sampai 0,5623 meter/sec bergerak ke arah tenggara, dan kecepatan minimum berkisar 0,0197 meter/sec sampai 0,2733 meter/sec bergerak ke arah tenggara. Sedangkan pada saat pasang menuju surut kecepatan maksimum berkisar 0,0530 meter/sec sampai 0,565 meter/sec bergerak ke arah barat laut dan kecepatan minimum 0,0067 meter/sec sampai 0,0525 meter/sec bergerak ke arah barat laut

The program is very important to help companies engaged in telecommunicationsinformation services as a substitute operator, thereby reducing the operational costs ofthe company. In addition the program also can help to achieve work efficiency of theData Entry especially the parts that need spelled out from a figure, and also makes iteasy for consumers to get information quickly and accurately regardless of humanerror that often occurs

Nitrogenase Activity and IAA Production of Indigenous Diazotroph and Its Effect on Rice Seedling Growth

The diazotroph bacteria as ecofriendly biofer-tilizers play an important role in improving the N status and availability of paddy soil. Laboratory experiment to study nitrogenase activity and IAA production of diazotroph from rice rhizosphere and to assess its effect on the growth of rice seedling has been conducted from September to October 2014 in Agronomy and Horticulture Laboratory Faculty of Agriculture Jenderal Soedirman University, Purwokerto. The experiment was arranged as a completely randomized design and consisted of seven treatments and provided with 4 replications. The treatments were the isolates of indegenous diazotroph (T1 = A11003, T2 = A230041, T3 = A24001, T4 = A230022, T5 = A230021, T6 = A230042 and T7 = without inoculation). The nitrogenase activity measured by acetylene reduction assay method and IAA production was measured by HPLC method. Plant height, leaf greeness, leaf area, total dry weight and total root length were determined on 21 days after sowing. The experimental results showed that the isolat A230021 was identified as Rhizobium sp. LM-5 and have the highest nitrogenase activity at 0.07 µM C2H4 ml-1 h-1 and IAA production reached 19.01 ppm. Inoculation with strains of diazotroph enhanced chlorophyl content, total root length, and biomass production
