Landscape Ecological Changes and Livelihood Dilemma of the Rural Household around the Oil Palm Plantation

The pressure of global market demand for palm oil is driving a massive expansion of oil palm plantations in Indonesia. Although it provides benefits in economic terms, it also has social and environmental impacts. The impact is in the form of changes in the ecological landscape, conversion of agricultural land, rural household livelihood systems, reduced biodiversity, deformation, plant monoculturalization, and even a monostructuring of livelihood. This study aimed to provide an overview of changes in the ecological landscape that resulted from the expansion of oil palm plantations and the socio-economic impact of the expansion of oil palm plantations on farmers' household livelihood systems. The study was conducted in West Sulawesi, Indonesia. This study uses the livelihood survey method by selecting 30 farmer households selected by random sampling. The results of the study found the fact that oil palm plantations seemed to provide welfare for rural households, but what happened was a vulnerability and high livelihood dependence on income from the wages of oil palm plantations. The expansion of oil palm plantations has created the integration and dependence of rural economies on the global political economy of oil palm, but at risk to even undergoing household livelihood dilemmas due to the two villages’ deliberate divergence of livelihoods because of shifting ecosystems now leading by palm oil commodities

Analysis of phosphate rock dissolution determining factors using principal component analysis in some acid Indonesian soils

Dissolution of phosphate rock (PR) materials and its subsequent phosphorus (P) availability to plants depend upon soil characteristics, PR characteristics, type of crops, and environmental conditions. Agronomic effectiveness of the PR sources has frequently been investigated in the field or in the greenhouse. This is time consuming and not cost-effective. Therefore, identification of the soil characteristics influencing the dissolution of PR is very important for direct application of P sources. The principal component analysis was used to summarize the characteristics of acid soils in an incubation system into a number of factors that may affect PR dissolution. Three major factors were selected in this study: 1) soil texture, 2) soil acidity, and 3) fertilization. Using the scores of the individual factors as independent variables, a stepwise regression analysis was performed to derive a PR dissolution function. The coefficient of determination (R2) reached 0.91**, and the magnitude of the different factors affect PR dissolution following the order of soil texture (54%) > soil acidity (43%) > fertilizer (3%). Fertilizer was not significant as a PR dissolution factor

Abstract - Currently, the number of companies offering health products is increasing over the years. This varied range of options available for customers has driven the researchers to dig out what the factors are that influence the intentions of purchasing by customers. The importance of this research was to actually realize what are the factors that could impact the behavior of customers in deciding which product to be purchased or to be bought.  The objectives of this research are to investigate the impact or relationship of customer knowledge, product performance, and health concern towards the purchase intention of consumers toward health products. In addition, the research is classified as a descriptive study to collect data by using a quantitative method. The researcher had distributed survey questionnaires to 201 respondents through online distribution after manual questionnaires have been answered by 20 respondents during the pilot test.  Data gathered and analyzed by using SPSS software. The results obtained showed significant influences between customer experience, customer attitude, perceived values, perceived usefulness, and health background on purchase intention of consumers toward health products. However, perceived ease of use and health awareness failed to achieve a significant correlation with the intention of purchase by consumers. Based on the discussions made on findings, this research may be able to be explored deeper view through further research in the future and eventually contributing to the industry.Keywords - Health products, customer attitude, customer experiences, perceived values, perceived usefulness, health background, purchase intention towards health product

Comparative study of photodegration of orange by solar and fenton process / Wan Abdul Rahim Wan Musa

Wastewater is exhausted in large volume every year due to the processes of textile industries such as dyeing am finishing processes. Nowadays, more than 50% of dyes used in textile industry are Azo-based dyes. Inorganic salts improve the coloration of the dye, which enhances the pollution load of wastewater from textile industries. Degradation of the reactive textile dye Orange Gelb (OG) was studied using Fenton's Reagent of Advanced Oxidation Processes (AOPs) and solar photo catalytic by TiO2. A laboratory set-up was designed to evaluate the effectiveness for both treatment. The initial concentration of OG in the reaction was 5 ppm. The effects of irradiation time and the condition of pH dye and concentrations of catalyst (TiO2, H2O2 and FeSO4) on the degree of degradation efficiency were studied. The results indicated that photo-Fenton's process is more effective than solar photo degradation by TiO2. The degradation effectiveness of Fenton's procedure was up to 79.22% in 2 hour rate at pH 3 and in 3.1 X 10-2 M, while the degradation efficiency of TiO2 was just up 19.75% at pH6 am in 5 ppm The degradation effectiveness of Fenton process increased as the concentration of OG dye decreased, the concentration of H202 increased, concentration of FeSO4 increased and pH value get decreased which is in more acidic. While for photo degradation for TiO2, the best degradation happened when TiO2 concentration increased, concentration of OG dye decreased, and ph value increased

Degree of phosphorus saturation and soil phosphorus thresholds in an ultisol amended with triple superphosphate and phosphate rocks.

Soil phosphorus (P) release capability could be assessed through the degree of P saturation (DPS). Our main objective was to determine DPS and, hence, P threshold DPS values of an Ultisol treated with triple superphosphate (TSP), Gafsa phosphate rocks (GPR), or Christmas Island phosphate rocks (CIPR), plus or minus manure. P release was determined by the iron oxide - impregnated paper strip (strip P), while DPS was determined from ammonium oxalate - extractable aluminum (Al), iron (Fe), and P. Soils were sampled from a closed incubation study involving soils treated with TSP, GPR, and CIPR at 0-400 mg P kg-1, and a field study where soils were fertilized with the same P sources at 100-300 kg P ha-1 plus or minus manure. The DPS was significantly influenced by P source x P rate, P source x manure (incubated soils), and by P source x P rate x time (field-sampled soils). Incubated soil results indicated that both initial P and total strip P were related to DPS by exponential functions: initial strip P = 1.38exp0.18DPS, R2 = 0.82**and total strip P = 8.01exp0.13DPS, R2 = 0.65**. Initial strip P was linearly related to total P; total P = 2.45, initial P + 8.41, R2 = 0.85**. The threshold DPS value established was about 22% (incubated soil). Field soils had lower DPS values <12% and strip P was related to initial DPS and average DPS in exponential functions: strip P = 2.6exp0.44DPS, R2 = 0.77**and strip P = 1.1DPS2 - 2.4DPS + 6.2, R2 = 0.58**, respectively. The threshold values were both at ≈8% and P release was 11-14 mg P kg-1. Results are evident that DPS can be used to predict P release, but the threshold values are environmentally sensitive; hence, recommendations should be based on field trials

Extractable Bray-1 phosphorus and crop yields as influenced by addition of phosphatic fertilizers of various solubilities integrated with manure in an acid soil

Soil extractable Bray-1 P (B1P) and response to phosphate (P) of Setaria anceps cv. Kazungula (Setaria grass) were monitored in a field trial bimonthly for 14 months in an acid soil fertilized with triple super phosphate (TSP), Gafsa phosphate rock (GPR) or Christmas Island phosphate rock (CIPR) integrated with or without manure. Extractable B1P from the same soil incubated with the same fertilizers in wet and dry 3-day cycles for 91 days was determined. Field experimental design was randomized complete block (RCB) with three replications. Results indicated that B1P magnitude for field and incubation trial were; TSP > GPR > CIPR, consistent with their solubility. An integration of manure and fertilizers resulted in much higher extractable B1P than sole fertilizers or manure. Over time, P availability decreased at a fast rate for the first 6 months and later was relatively constant. The dry matter yields (DMYs) exhibited quadratic relationships with P rates. Maximum DMYs (6-11 t ha-1) were attained between 100 and 200 kg P ha-1, above which they declined. Average DMYs were not significantly different for TSP, GPR and CIPR (6.1-6.6 t ha-1). Maximum individual DMY were attained at 2-6 months and then declined to a minimum (2-4 t ha-1) after 1 year. Cumulative yields (20-55 t ha-1) also were not significantly different for the three fertilizers. Manure-CIPR integration increased DMY whilst in GPR and TSP/manure combinations DMYs were depressed. The PRs could supplement the expensive TSP without loss of yields but the non-reactive PR should be integrated with manure. © 2009 Springer Science+Business Media B.V
