In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 47-57. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This research aims to study the effect of the application of Palm Oil Mill (POME) on the physical and chemical characteristics of the soil as well as the growth and yield of soybean (Glycine max L.). Field experiments were carried out on Ultisols soil in Bangka Regency, Bangka Belitung Islands Province. The treatments included chemical fertilizers (75 kg urea/ha, 100 kg SP-36/ha, 50 kg KCl/ha) without POME (L) and POME application at a dose of 75,000 L/ha (L1), 150,000 L/ha (L2), 225,000 L/ha (L3), and 300,000 L/ha (L4). The experiment used a simple randomized group design with 4 replications. The experimental results showed that POME application had a significant effect on soil K-dd at 30 DAP, several primary branches, and soybean yield per plot but had no significant effect on total pore space, permeability, pH, C-organic, and P-available at 30 DAP and 60 DAP and soil K-dd at 60 DAP and soybean plant height. The highest soybean yield was 2.72 tons/ha obtained by treatment L4 (300,000 L POME/ha)

Phosphate Adsorption Capacity and Organic Matter Effect on Dynamics of P Availability in Upland Ultisol and Lowland Inceptisol
Get PDFUltisols and Inceptisols were used to investigate the adsorption-desorption capacity of P and the effect of organic matter on the dynamics of P availability in tropical acid soils. The experiment consisted of two sub-experiments. Sub-experiment I was to study the adsorption-desorption capacity of Ultisols, Fresh-water lowland Inceptisols, and tidal-swamp Inceptisols. Therefore, surface soils (0 to 30 cm) of each tested soil were treated with 0, 10, 20, 30, 40, 60, 80, 100, 120, 140, 170, and 200 mg P kg-1 of soil. Sub-experiment II was to study the effects of organic matterapplication (0, 5, 10, and 15 Mg ha-1) on the dynamics of available P following 60d incubation under room temperature.P fertilizer application significantly affected water soluble-P (WSP) (p<0.01) and soil available P-Bray and Kurtz No. 1 (BKP) (p<0.01) in the three tested soils. The different response of both WSP and BKP confirmed that the soils tested in the current experiment had different soil P buffering capacity in the order of Tidal-lowlandInceptisol>Upland Ultisol>fresh-water Lowland Inceptisol. OM application increased the BKP in all tested soils as compared to the control. Differences in pattern of soil available P dynamics over time were detected between upland soil and two lowland soils used in the current experiment

Suspended load and bed load sediment transport are important component for the sediment transport in surf zone. The\ud
purpose of this study is to obtain a good model for sediment transport in surf zone by combining a quasi-2D sediment\ud
transport model and the Bagnold-type sediment transport model. The quasi-2D sediment transport model is used to\ud
simulate the suspended load transport, while the Bagnold-type for the bedload transport. A quasi-2D numerical wave\ud
model called Funwave was expanded to accommodate the sediment transport model. The model is validated by the\ud
published data for sediment transport in a wave flume. Two mode of morphological change is compared to evaluate the\ud
influence of wave-current (mode A) and instantaneous bottom velocity (mode B) in the third and forth velocity moment\ud
of Bagnold-type sediment transport model. Four sets of bed load transport parameters are evaluated to calculate bed\ud
level change. The evaluation shows that although eB exceeds one, it can produce bed level change similar to that by\ud
using the parameters proposed by Bailard. Parameters proposed by van der Molen calculated very high bed level\ud
change, while Gallagher???s parameter produced relatively small bed level change. The performance of two modes of\ud
morphological change shows that mode A produce much better morphological change than mode B in surf zone for the\ud
bedload transport component. While for the suspended load component, mode B produces very high erosion in surf\ud
zone. Coupling of mode B and a wave motion-induced suspended load transport gives comparable morphological\ud
change to the experimental data
62 anos de relações diplomáticas entre a Indonésia e o México: algumas reflexões e caminhos a serem seguidos
Get PDFThe paper attempts to discuss the Indonesia-Mexico diplomatic relations over the last 62 years (1953-2015). The paper shows that during the Soekarno administration, Indonesia and Mexico enjoyed the peak momentum of the bilateral political relations. The bilateral relations deteriorated during the Soeharto regime, despite some re-invigoration to strengthen economic relations were visible in the later period. In the post-Soeharto regime, the bilateral relations have strengthened, particularly in the economic sphere. The paper pointed out that there is plenty space that both countries could do to strengthen the bilateral relations. But to achieve this goal, both countries need to have strong political willingness, work hard and address the inherent matters and issues in an innovative and creatively manners. In the economic sphere, both states need to find creative ways on how to evolve from being a competing partner to become an emerging collaborative partner. To support the Indonesian economic diplomacy programs, Indonesia should also needs to strengthen the socio-cultural and political cooperation. The paper views that achieving a so-called ‘comprehensive partnership’ as agreed by both Head of States in the Joint Statement 2013 is seems to be a visible goal to be achieved in the near future.El artículo discute las relaciones diplomáticas entre Indonesia y México durante los últimos 62 años (1953-2015). Muestra que durante la administración Soekarno, Indonesia y México disfrutaron del punto más alto en sus relaciones políticas bilaterales. Éstas se deterioraron durante el régimen de Soeharto, a pesar de alguna revitalización para fortalecer las relaciones económicas que fue visible en su periodo tardío. En la etapa posterior al régimen Soeharto, las relaciones bilaterales se han fortalecido, sobre todo en la esfera económica. El artículo señala que hay mucho espacio el cual ambos países podrían aprovechar para fortalecer las relaciones bilaterales. Pero, para alcanzar esta meta, ambos países necesitan tener una fuerte disposición política, trabajar duro y afrontar los temas y problemas inherentes de maneras innovadoras y creativas. En la esfera económica, ambos estados necesitan encontrar maneras recursivas para evolucionar de ser socios competidores a convertirse en socios colaboradores emergentes. Para apoyar los programas diplomáticos y económicos de Indonesia, ésta también necesita fortalecer la cooperación sociocultural y política. El artículo sostiene que alcanzar una llamada “cooperación plena”, como fue acordado por ambos jefes de estado en la Declaración Conjunta de 2013, parece ser una meta visible de lograr en el futuro cercano.

Penguatan Diplomasi Ekonomi Indonesia Mendesain Clustering Tujuan Pasar Ekspor Indonesia: Pasar Tradisional Vs Pasar Non-tradisional
Get PDFStudi ini dimaksudkan untuk mengklasifikasi tujuan pasar ekspor Indonesia dengan metode kuantitatif analisis statistik deskriptif selama periode 1962-2015 sehingga dapat menghasilkan sebuah clustering tujuan pasar ekspor Indonesia secara konkrit. Clustering tujuan pasar ekspor Indonesia dibagi menjadi dua macam: pasar tradisional dan pasar non-tradisional (pasar kspor sudah berkembang dan untapped markets). Hasil analisis menyimpulkan bahwa negara-negara yang masuk dalam kategori pasar tradisional bagi Indonesia sebanyak 12 (dua belas) negara yaitu: Australia, Jerman, Italia, Jepang, Korea Selatan, Belanda, Malaysia, Filipina, Singappura, Inggris Raya, Amerika Serikat dan Tiongkok (termasuk Hong Kong). Sedangkan pada kategori pasar non-tradisional untuk klasifikasi negara-negara ekspor sudah berkembang ditemukan terdapat sebanyak 9 (sembilan) negara yaitu Belgia, Perancis, India, Arab Saudi, Uni Soviet (dan Federasi Rusia), Spanyol, Thailand, Trinidad and Tobago dan Vietnam. Sedangkan untuk kategori pasar yang belum digarap (untapped markets) adalah seluruh negara dan entitas ekonomi selain diatas (sebanyak 219 negara dan entitas ekonomi). Secara keseluruhan, hasil studi clustering tujuan pasar ekspor Indonesia ini dapat dikatakan cukup selaras dengan banyak pernyataan yang sebagaimana disampaikan oleh pejabat Pemerintahan RI
Analisa Model Fungsi Impor Indonesia Dengan ASEAN Dan China Periode 1980 – 2010
Get PDFMakalah ini dimaksudkan untuk memotret dan mengevaluasi model fungsi imporIndonesia dalam lingkup regional ASEAN dan China selama periode 1980-2010. Gunamenganalisis fungsi impor Indonesia, studi ini menggunakan penyederhanaan modelfungsi impor yang dikembangkan oleh Uemura (2005). Dalam studi ini terdapat duamodel fungsi impor yang dimanfaatkan yakni model fungsi impor tradisional dandimodifikasi. Hasil estimasi model fungsi impor tradisional Indonesia dalam lingkupregional ASEAN dan China selama periode 1980-2010 tampak bahwa hanyaimpor/ekspor untuk komoditi primer antara Indonesia dengan ASEAN saja yangberkointegrasi (memiliki hubungan jangka panjang). Sedangkan untuk komoditimanufaktur tampak bersaing dengan sangat ketat. Studi menemukan bahwa terdapathubungan antara impor komoditi primer dengan ekspor komoditi yang sama antaraIndonesia dengan China tampak signifikan. Akan tetapi tidak terdapat hubungan yangsignifikan antara pertumbuhan PDB Indonesia dengan nilai impor komoditi ini.Gambaran yang diberikan model ini menunjukkan bahwa prospek perdagangankomoditi primer Indonesia cukup mendapat tempat di pasar China. Terdapatnyahubungan yang positif antara pertumbuhan ekspor dengan impor perlu dicermatikarena tidak menutup kemungkinan Indonesia akan menderita kerugian dariperdagangan yang terjadi. Sedangkan untuk hasil estimasi model fungsi impormodifikasi ditemukan bahwa perdagangan Indonesia dengan negara-negara ASEANuntuk komoditi impor primer dalam jangka panjang dipengaruhi oleh nilai ekspor, PDB,dan kurs masing-masing pada periode setahun sebelumnya. Hal ini menggambarkankomoditi ini memiliki tingkat persaingan yang cukup tinggi, karena setiap kenaikanekspor akan diikuti dengan peningkatan nilai impor. Nilai koefisien PDB yang negatifmenunjukkan bahwa pertumbuhan perekonomian berdampak positif terhadapperdagangan luar negeri komoditi primer ke ASEAN, dimana pertumbuhan ekonomimemicu pengurangan nilai impor. Hasil estimasi model juga menunjukkan bahwa dalamjangka pendek nilai transaksi ekspor memberikan pengaruh yang signifikan padapeningkatan nilai impor
