Abstract

The experiment of sustainable technology application with casting organic fertilizer and styloassociation with King grass was conducted at Siut Cattle farm at Gianyar regency. The experimentdesign was a randomized block design arranged in Split-plot pattern and was replicated threetimes. The treatment consisted of two factors as follows: (1) two types of cropping systems as mainplot (King grass monoculture and King grass – stylo association), (2) four levels of casting organicfertilizer as sub-plot (0, 10, 20, dan 30 t ha -1). The variable studied were: forage production,production characteristic, and leaf characteristic. Leaf characteristic variable consisted of: leafarea, leaf color, and leaf thickness. The results showed that: casting organic fertilizer weresignificantly (P<0.05) effect on leaf area and leaf production. Cropping system was not significantly(P>0.05) effect on all of variable studied. There was no significantly interaction (P>0.05) foundedbetween cropping system and casting organic fertilizer on all of variable studied. The conclusion ofthese experiment were: casting application at King grass and its association with stylo wasincreased forage production at first regrowth. The optimal levels of casting organic fertilizer in Kinggrass monoculture and that association with stylo were 17.09 dan 16.41 t ha -1 respectively.

Abstract

Eksistensi subak sebagai warisan budaya mulai terancam akibat alih fungsi lahansawah yang terus meningkat sejalan dengan pesatnya laju pembangunan, terutama disektor pariwisata. Alternatif yang dapat ditempuh untuk menekan alih fungsi lahan sawahyaitu  melalui optimasi penggunaan lahan dengan menerapkan usaha tani bernilai tinggi,seperti hortikultura untuk konsumsi hotel dan tanaman obat. Agar perencanaanpengembangan komoditas pertanian dapat dibuat akurat dan efektif,  maka perlu didukungdata karakteristik lahan yang yang lengkap dan mutakhir. Tujuan penelitian ini yaituuntuk mengevaluasi kesesuaian lahan untuk pengembangan komoditas tanamanhortikultura dan obat, dan menyusun arahan pertanian perkotaan berbasis lingkungan,peluang pasar, dan perlindungan subak.Metode yang digunakan dalam penelitian yaitu survey lapangan dengan subak sebagaiunit pengambilan sampel. Sifat-sifat tanah dianalisis dengan metode analisis tanah yangtelah baku berlaku di laboratorium. Kelas kesesuian lahan ditentukan berdasarkan faktorpembatas minimum dengan matching system yaitu membandingkan antara kualitas lahandengan persyaratan tumbuh tanaman menurut Zainudin, dkk., 1997. Arahan penggunaanlahan disusun berdasarkan kelas kesesuaian lahan tertinggi, konsevasi subak, dan filosofibudaya Bali.Hasil penelitian menunjukkan, bahwa kesesuaian lahan untuk padi tergolong sangatsesuai (S1), untuk sayuran, buah-buahan, dan tanaman obat tergolong sesuai (S) dengandua faktor pembatas yaitu drainase buruk dan tekstur tanah halus. Dalam pengelolaantanaman tersebut diperlukan pembuatan saluran drainase untuk memperbaiki drainasedan penambahan bahan organik untuk memperbaiki tekstur tanah. Arahan penggunaanlahan pertanian di Denpasar, pada musim hujan diprioritaskan untuk bertanam padimengikuti pola rotasi tanaman dan zonasi penanaman komoditas pertanian, seperti jenisbunga-bungaan di bagian utara, jenis buah-buahan dan sayuran di bagian tengah, sayurandan tanaman palawija di bagian selatan.

Abstract

The utilization of industrial wastewater into a versatile material that has been the focus of research for economics reasons, environmental and technical. One of the proposed industrial wastewater for a new useful material is wastewater from the desalination process which is also known as brine water. The magnesium content in brine water is able to used as a source of magnesium for the synthesis of Mg/Al hydrotalcite-like compound (Mg/Al HTlc). Mg/Al HTlc are widely investigated for their potential applications in research and industrial processes as adsorbents, catalysts and /or catalyst precursors and pharmaceutical industry excipients. As adsorbents, Mg/Al HTlc are receiving greater interests in the environmental community due to their high adsorption capacity. However, before using natural brine water, has conducted a preliminary study the synthesis of Mg/Al HTlc by using artificial brine water as a model of desalination wastewater. The objective of this research is to synthesis of Mg/Al HTlc from artificial brine water and its ability tested as a methyl orange (MO) adsorbents. The research initiated with the synthesis of Mg/Al HTlc from artificial brine water. Characterization of the Mg/Al HTlc synthesized was confirmed through X-ray Diffraction and FT-IR Spectroscopy. The determination of optimum acidity, adsorption rate, and energy and capacity adsorption were studied. The result showed that pH 3 was the optimum acidity for the adsorption of MO on Mg/Al HTlc. MO was adsorbed at first order adsorption rate of 7.30 × 10-4 s-1 on the Mg/Al HTlc, the adsorption capacity and adsorption energy were 4.36 × 10-5 mol g-1 and 27.54 kJ mol-1, respectively. From the preparatory process and the synthesis of Mg/Al HTlc by using artificial brine water to provide the information that the byproduct of desalination processes (brine water) which are believed to be used for the synthesis of Mg / Al HTlc.

Abstract

AbstractMercury (Hg) and lead (Pb) are two heavy metals which run-off with waste water of industry,market, and office to territorial water of Jakarta Bay. Fishing ground in adjacent water ofMarunda, Bidadari Island, and Damar Island have been contaminated by Hg and Pb.Pelagic fish caught in Jakarta Bay have not been contaminated by Hg and Pb. However,demersal fishes that have been caught in the same area, a positively contaminated with Hgand Pb. The rate of Hg and Pb in fishing ground are signicantly influence by the rate of Hgand Pb in pelagic fish (NK Hg = 0,895 at sig 0,016 and NK Pb = 0,962 at sig 0,002) and indemersal fish (NK Hg = 0,825 at sig 0,043 and NK Pb = 0,894 at sig 0,016). The pattern ofHg contamination in fishing ground to pelagic fish and demersal fish each following linearmodel Y = -0,055 + 5,314 X, and quadratic model Y = -1,370 + 215,549X – 4190,579X2, where Xrepresents rate of heavy metal in fishing ground and Y represents rate of heavy metal in fishcaught by fisherman. While pattern of Pb contamination of fishing ground to pelagic fishand demersal fish each following cubic model Y = -0,006 +1,114X - 399,652X3 and sigmoidmodel Y = e0,627 – (0,10 / X).

Abstract

Diarrhea is one of the main reasons of infant mortality in Indonesia. Diarrhea is also a negative impact of interaction between human beings and the environment. The aims of reasearch to know the influence of environment sanitation of house area and social economical characteristics of household toward diarrhea at infant in NTT. Design used secondary data from Susenas 2012 by using household sample for 4 triwulan as many as 10,702 household in all the regencies/city. Unit of analysis consists of both household having infants suffer diarrhea and infants did not suffer from diarhea, so that the amount of household that was researched were as many as the amount of infants in the household namely 5.783. The analysis method was descriptive analysis and inferensial, meanwhile the tool of statistics was by using the logistics regression. The result showed that the variable influences diarrhea at children under five years based on logistics regression was environment sanitation that was non-improved source (OR = 1.484; 95%CI = 1.180 – 1.867), source of water that was non-improved source (OR = 1.516; 95%CI = 1.097 – 2.095), type of tile from soil (OR = 1.439; 95%CI = 1.139 – 1.818), age of infant less than 24 month (OR = 1.294; 95%CI = 1.043 – 1.606), education of household is low (OR = 1.412; 95%CI = 1.010 – 1.973), and without breast feeding (OR = 1.898; 95%CI = 1.001 – 3.601). There was a significant relationship between source of water, condition of improved source sanitation, type of tool, age of children under five years, education of the head of household, and breast feeding with the diarrhea at children under five years (p = 0.000). The risk factor that was proved to influence diarrhea at children under five years was source of water that was non-improved source, condition of environment of house area that was not healthy, type of tile from soil, age of infant less than 2 year, education of the head of household was low, and there was no breast feeding given.
