Research aims to test the effectiveness of various types of manure combined with various doses of application for the growth and result of shallot varieties of Palu Valley. This research was designed using factorial randomized block design. The first factor was manure with three types of treatment, namely chicken manure (P1), got manure (P2), cow manure (P3). The second factor was the dose of manure consisting of three types of treatment, namely 10 t ha-1 (3,6 kg plot-1) (D1), 20 t ha-1 (7,2 kg plot-1) (D2), 30 t ha-1 (10,8 kg plot-1) (D3). The results show that the combination of various types of treatment and doses of chicken manure interacts on plat height parameters aged 35 days after planting. The treatment of chicken manure with a dose of 30 t ha-1 gives better results. The single treatment of chicken manure gave better results for the plant height, weight of leaves, root dry weight, leaf dry weight , number of tubers per clump. Single treatment of manure dosage of 30 t ha-1 gave better results on plant height, leaf area , leaf fres weight, leaf dry weight tuber fresh weight per hectare.

A study that was aimed to elucidate roles of Gliricidia sepium and Tithonia diversifolia composts and their extracted humic and fulvic acids on aluminum concentration in an Ultisol was conducted in a laboratory. Those composts and humic and fulvic acids extracted from them were mixed with soil and incubated for 90 days. Results of the study showed that the highest decrease in exchangeable Al concentration (90,5%) was observed for Tithonia fulvic acid treatment during 90 days, followed by Tithonia compost (88,4%), Gliricidia fulcic acid (82,3%), Gliricida compost (82,2%), Gliricidia humic acid (82,3%), and Tithonia humic acid (75,7%) treatments. In general, rate of change in exchangeable concentration was fast for the first 45 days, but it then slowed down during the second 45 days (45-90 days). This was particularly observed for humic and fulvic acid treatments, whereas compost treatment still showed subsequent decrease. It was concluded that roles of humic and fulvic acid in reducing exchangeable Al was only a short term, whereas compost played roles in a long term. In terms of capability in reducing exchangeable Al, Tithonia compost and its humic and fulvic acids was better than Gliricidia compost and its humic and fulvic acids

A glasshouse experiment was conducted to judge the beneficial effects of Gliricidia sepium and Tithonia diversifolia composts on plant growth improvement, P availability and reduction of aluminium concentration in an Ultisol. Thirteen treatments consisting of two composts, six rates of each compost (5, 7.5, 10, 20, 40 and 80 t/ha) and one control (no added compost) were arranged in a randomized block design with three replicates. Each mixture of compost and soil was placed in a pot containing 8 kg of soil, and maize of Srikandi cultivar was grown on it for 45 days. At harvest, plant P content, soil pH, and soil aluminium concentration were measured. Results of this study showed that application of Gliricidia and Tithonia composts significantly reduced Alo concentration, increased Alp content, increased soil pH, increased P availability, and increased P taken up by maize grown for 45 days. The optimum rate of both Gliricidia and Tithonia composts should be 45 t/ha. However, at the same rate, optimum production gained by application of Tithonia compost would be higher than that of Gliricidia. This was due primary to the difference contents of humid acid and fulvic acid of the composts

This study aimed to determine the growth and yield of shallot Lembah Palu variety planted on dry land with different direction and form of seedbeds. It have been carried out in January-April 2013 in the village of Guntarano, Tanantovea Sub Districts, District of Donggala, Central Sulawesi. This study used a Spilt Plot Design. The main plot was the seedbed direction (A) consisting of: (A1) = seedbeds in the direction of the slope of the land, and (A2) = seedbeds crossed the slope direction. Sub-plot was the form of beds (B) comprises of: (B1) = depth seedbeds and (B2) = high seedbeds. Each treatment was repeated 3 times, so that there were 12 experimental units. The research found that (i) the direction of the beds as well as its interaction with the form of beds did not significantly affect the growth and yield of shallot ‘Lembah Palu’ on dry land. (ii) depth seedbeds produces the number of leaves, leaf length, leaf dry weight, total leaf areaper plant, and total dry weight per plant, and the number of tubers per clump and the weight of the harvested dry tuber per hectare was higher than high seedbeds form.

The tendency of more intensive use of chemicals in agricultural cultivation activities causes an imbalance of other nutrients and decreases the content of soil organic matter. This causes degradation of soil fertility and residues of active pesticides that threaten the sustainability of farming. The community partnership program (PKM)aimed to provide solutions to problems faced by partners in both the production and management fields by providing counseling, demonstrations and assistance. The method activities is participatory rural appraisal (PRA) in applying appropriate technology and empowerment, with partners in these activities being members of the "Batu Sari" farmer group in Astina Village, Torue District, Parigi Moutong Regency. The results of the implementation of community partnerships show an increase in knowledge and skills and attitudes of farmers. The production of organic fertilizers, vegetable pesticides and bioinsecticides carried out by the activity participants went well and could be used as expected. The system of rice intensification (SRI) cropping system can be implemented by partner farmers. partner farmer groups become independent in carrying out their farming activities using assembled technology that has been practiced

The aims of this experiment were to obtain a suitable combination of planting medium and gibberelline concentration for the germination and growth of nutmeg seeds; to obtain a suitable planting medium as well as gibberelline concentration for the germination and growth of nutmeg seeds. This experiment used Split Plot Design and was arranged in Completely Randomized Design. Two factors were tested, namely concentration of gibberelline and the type of planting media. Concentration of gibberelline was ploted as main plot, with three concentrations tested, namely 200 ppm, 250 ppm and 300 ppm. The types of planting media were ploted as subplot with three types of planting media tested, namely sand, coco peat and sawing peat. Therefore, there were nine treatment combinations which each treatment combination was repeated three times. Data was analysed by using analysis of variance and followed by HSD at 5%. Results of this experiment indicated that nutmeg seeds soaked into gibberelline solution and germinated in coco peat medium produced more root numbers and higher normal germination dry weight; and the highest number of roots as well as the highest normal germination dry weight were obtained when seeds were soaked into 250 ppm gibberelline and germinated in coco peat medium. The number of roots and dry weight of normal germination on such treatment combination were 10.67 roots and 2.01 g per germinating seed. Coco peat medium was better for the germination and growth of nutmeg seeds as indicated with the highest germination rate, growth rate, length of plumula, length of roots, total length of roots as well as the ratio of plumula length and root length. The soaking of seeds into gibberelline had a relatively similar effect on the germination and growth of nutmeg seeds, except if the seeds were soaked into 250 ppm gibberelline and germinated in coco peat medium which produced the highest number of roots and the highest normal germination dry wieght.

ABSTRACTMost upland soils are poor in organic matter and have high temperature. The utilization ofmulch and organic manure with appropriate dosage are expected to enhance the physical andchemical conditions of the soil and the production of shallot. This study aimed to determine the effectof applying various types of mulch and cow urine bioculture on the growth and yield of shallot. Theresearch was conducted in March to June 2017 in Oloboju Village, Sigi Biromaru District, SigiRegency, Central Sulawesi Province. A randomized block design factorial with two factors was usedin this study. The first factor was the various types of mulch, namely: Gliricidia sepium leaves, ricestraw, and plastic mulch. The second factor was the frequency of bioculture, namely: without cowurine bioculture, two times and four times application. Thus, there are nine in the combination oftreatments and repeated three times and therefore there were 27 experimental units. The resultsshowed that interaction of rice straw mulch and four times cow urine bioculture application have avery significant effect on the growth and production of shallot. The use of 3 ton ha-1 rice straw andfour times cow urine bioculture application frequency produced 11.25 ton ha-1 shallot bulb.Keywords: chemical properties, gliricidia leaf, organic matter, rice straw, soil physicalABSTRAKLahan kering umumnya memiliki kandungan bahan organik yang rendah dengan suhu yangtinggi.

One technique to secure data is to use the Advanced Encrypt on Standard (AES) 128 method. The Advanced Encrypt on Standard (AES) method can be applied in improving data security, especially at the Central Sulawesi Provincial Inspectorate. The data in question are audit reports of BOS funds (School Operational Assistance), reports of special investigations into violations of regional finances and reports of violations of civil servant discipline (PNS). The data must have a high level of security, so that it is not easily known by irresponsible parties and will have a negative impact and be misused. The conclusion in this study was obtained that, the AES-128 algorithm can be used as an alternative to the process of improving data security, namely by encryption and decryption. The results of encryption can be guaranteed as long as the symmetry key encryption is not leaked to irresponsible parties
