The Composition of Spesies and Changes in Reef Fishes Community at Ecoreef Rehabilitation Site, Manado Tua Island, Bunaken National Park

The study conducted from 2006 to 2012 with an interval of every two years in the ecoreef area of ​​ Manado Tua island found 2,936 individual reef fishes of 181 species that include into 32 families. Species composition value of the 10 dominant species of reef fishes was 55.48% of the total species. The highest number of species was Plotosus lineatus with schooling behavior which only discovered in 2010 at a depth of 3 meters. Ecoreef area of Manado Tua island, when analyzed from the abundance and biomass of reef fishes exhibited a succession of reef fish that have been stable, with peak abundance and higher biomass in 2008 and 2010. Reef fish found in ecoreef seemed to start a new living and become a new habitat for them. These were indicated by the highest biomass during the previous year but the number of individuals and spesies were decline. There was no change in the structure of reef fish communities in the ecoreef area of Manado Tua Island, which characterized by non significant different ecological index between the years. Cluster analyses grouped reef fish species into 2 groups i.e., the group of 2006 and the group of 2008, 2010, and 2012. Early survey in 2006 showed lower abundance of reef fish species for allegedly associated with low ecoreef organisms

Pemanfaatan Limbah Penyulingan Serai Wangi Sebagai Pupuk Organik Terhadap Pertumbuhan Dan Produksi Kacang Tanah (Arachis Hypogea L.)

Kacang tanah merupakan salah satu jenis kacang-kacangan yang mempunyai nilai gizi tinggi. Akan tetapi produksi kacang tanah di Indonesia masih rendah dibandingkan dengan negara lain. Untuk meningkatkan produktivitas kacang tanah perlu dilakukan penambahan nutrisi pada tanaman namun dengan mahalnya harga pupuk perlu dicari alternatif lain. Untuk itu dilakukan penelitian pemanfaatan abu limbah penyulingan serai wangi menjadi pupuk organik untuk meningkatkan produktivitas kacang tanah. Penelitian ini dilakukan di Kebun Percobaan Balittro Laing Solok sejak September sampai Desember 2017. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan yaitu pemberian abu limbah penyulingan serai wangi dengan dosis : 1) 200 g 2) 250 g 3) 300 g dan 4) 0 g pada 8 tanaman per plot diulang 6 kali. Benih kacang tanah ditanam dalam kantong berukuran 45 x 60 cm yang berisi media tanah dan pupuk kandang dengan volume 1 kg/kantong. Variabel yang diamati meliputi tinggi tanaman, jumlah cabang, jumlah polong, bobot basah, bobot kering serta bobot kering/100 biji. Pengamatan pertumbuhan dilakukan setiap dua minggu dimulai tiga minggu setelah tanam. Hasil penelitian menunjukan bahwa pertumbuhan vegetatif dan produksi tanaman kacang tanah mempunyai perbedaan yang signifikan dari setiap dosis abu limbah penyulingan yang digunakan. Dengan hasil yang terbaik pada dosis abu limbah serai wangi 300 g/kantong terlihat pada tinggi tanaman, jumlah cabang, jumlah polong, berat basah, berat kering dan berat per 100 biji berturut-turut 46,82 cm, 4,76 buah, 37,72 buah, 80,31 g, 35,40 g dan 62,36

Enhancement of voltage stability in an interconnected network using unified power flow controller

In this paper, the optimal placement of Unified Power Flow Controllers (UPFC) in a large-scale transmission network in order to improve the loadability margin was considered. In other to achieve this aim, the Line Stability Factor (LQP) as a technique for the optimal location of UPFC in the IEEE 14-bus network and 56-bus Nigerian national grid was adopted. The power injection model for the UPFC was employed to secure improvements in the loading margin of the IEEE 14-bus network and 56-bus Nigerian national grid system. Continuation power flow was used to assess the effect of UPFC on the loadability margin. Steady-state simulations using Power System Analysis Toolbox (PSAT) on MATLAB was applied to determine the effectiveness of placing UPFC between bus 13 and bus 14 in the IEEE 14-bus network and between bus 44 (Ikot-Ekpene) and bus 56 (Odukpani) in the 56-bus Nigerian national grid system. The results showed that the loadability margin increased by 8.52 % after UPFC was optimally placed in the IEEE 14-bus network and increased by 195.5 % after UPFC was optimally placed in the 56-bus Nigerian national grid system. Thus, these enhance the voltage stability of both network and utilizing the network efficiently

Inter-Market and Seasonal Variation in Price: An Appraisal of Maize Marketing in Kwara State.

This study investigated inter-market and seasonal variation in prices of maize in Kwara State. Secondary time series data on average monthly retail price of maize in urban and rural markets between 1998 and 2003 were used for the study. Primary data on the average storage cost of maize and the average selling price of maize for 2004 were also used for the study. The study described the seasonal pattern of maize, examined its seasonal price rise and analyzed the inter-market variation in prices of maize in the study area. The study revealed that the seasonal price rise exceeds storage cost but the difference is minimal. The effect of kilometer separation between market- pairs on their Price difference is significant (p < 0.05). Thus, if storage cost should be reduced the inter-market price variation will be reduced while transportation cost should also be reduced to facilitate the movement of food commodities between markets. Keywords: Inter-market, Price difference, Seasonal, Variation, and Maize. Agrosearch Vol. 7 (1&2) 2005: pp. 51-6

Pengetahuan Lokal Masyarakat Adat Kasepuhan: Adaptasi, Konflik dan Dinamika Sosio-Ekologis

Masyarakat Kasepuhan merupakan masyarakat adat Sunda yang hidup di sekitar Taman Nasional Gunung Halimun - Salak (TNGHS). Masyarakat adat ini mempunyai kekhasan dalam mengatur kehidupan warganya dalam berelasi dengan alam. Melalui konsep pancer pangawinan masyarakat mensandarkan kehidupannya pada keterikatan atas tanah. Permasalahannya sekarang adalah sejak diterbitkannya kebijakan perluasan Taman Nasional melalui SK Menteri Kehutanan Nomor 175/Kpts-II/2003, tanah yang dulu dikuasai oleh masyarakat berubah status menjadi tanah Taman Nasional. Perubahan status tanah tersebut menyebabkan hilangnya akses masyarakat terhadap tanah. Kondisi ini menempatkan masyarakat pada kondisi konflik dengan Pengelola TNGHS. Metode penelitian ini adalah kualitatif dengan paradigma konstruktivisme (Denzin, 2000). Teknik pengumpulan data melalui indepth interview, observasi partisipan, dan Focus Group Discussion (FGD). Hasil dan temuan penelitian menunjukkan adanya pengetahuan lokal masyarakat Kasepuhan dalam hal mengatur kelestarian lingkungan dan bagaimana lingkungan tersebut dapat memberi manfaat untuk kehidupan masyarakat. Misalkan dengan adanya konsep Ibu Bumi, Bapak Langit dan Guru Mangsa, Leuit dan Wewengkon Hutan. Pengetahuan ini telah dikembangkan secara turun temurun dan mengatur relasi masyarakat dengan alam (hutan). Namun pertarungan pengetahuan masyarakat lokal dan pengelola TNGHS telah menyebabkan teralienasinya pengetahuan lokal tersebut. Dengan mengacu pada konsep Escobar (1999), maka dapat disimpulkan bahwa pengetahuan lokal dalam mengelola sumber daya alam dapat dipandang sebagai rezim alam organik, dimana sejak diberlakukannya SK Menteri Kehutanan tentang perluasan TNGHS, masyarakat lokal dengan alam organiknya sedang berhadapan dengan pengelola TNGHS selaku rezim alam negara yang dalam prakteknya bertumpu pada pengetahuan kapitalis dan tekno, dalam memperjuangkan hak akses atas tanah
