Abstract

Penelitian ini bertujuan untuk mengetahui kondisi optimum sintesis Carboxymethyl Cellulose (CMC) melalui kombinasi perlakuan Kalium Hidroksida (KOH) Natrium Monokhlor Asetat (NaMCA) dan suhu yang optimal serta identifikasi karateristiknya melalui rendemen, viskositas, Derajat Subsitusi (DS), Water Holding Capacity (WHC), dan Oil Holding Capacity (OHC). Penelitian ini menggunakan Response Surface Methodology (RSM) dengan 3 faktor dan 5 level masing ? masing NaMCA (3,18-6,68g) dalam 20 ml KOH (11,59-28,41%), 100 ml isopropanol pada suhu (46,59-63,41oC). Parameter pengamatan meliputi rendemen, viskositas, derajat subsitusi (DS), Water Holding Capacity (WHC), dan Oil Holding Capacity (OHC). Hasil penelitian menunjukkan bahwa kondisi optimum sintesis CMC terhadap karateristiknnya diperoleh pada kombinasi perlakuan pada konsentrasi KOH 20% (w/v), NaMCA 5 gram dan suhu pada 47,60oC, dengan diperoleh nilai rendemennya sebesar 7,5226 gram, DS sebesar 0,82, WHC sebesar 6,51 g/g, OHC 3,59 g/g, dan nilai viskositasnya 0,095 cp.

Abstract

Sterilisasi eksplan merupakan salah satu faktor penting yang perlu diperhatikan dalam melakukan kultur jaringan, guna mengeliminir berbagai sumber kontaminan yang terbawa pada eksplan, termasuk untuk induksi kalus.  Salah satu zat pengatur tumbuh yang digunakan untuk induksi kalus adalah 2,4-D(2,4-Dichlorophenoxyacetic acid).  Penelitian dilakukan dalam dua tahap.Percobaan sterilisasi eksplan bertujuan untuk mengetahui bahan sterilan yang lebih baik untuk sterilisasi eksplan umbi bawang merah lokal Palu.Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan berbagai bahan kimia sterilan yaitu deterjen, fungisida, cloroxs, tween 80, bakterisida dengan atau tanpa pembakaran(perlakuan fisik) dengan 4 ulangan.Tahap induksi kalus bertujuan untuk menentukan konsentrasi zat pengatur tumbuh 2,4-D yang baik dalam menginduksi kalus dari eksplan bawang merah lokal Palu.  Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan berbagai konsentrasi 2,4-D yaitu M1 = 1,0 ppm, M2 = 1,5 ppm, M3 = 2,0 ppm dan M4 = 2,5 ppm, yang diulang 4 kali. Hasil penelitian menunjukkan bahwa penggunaan bahan sterilan 1g bakterisida, 1g fungisida, 10% cloroxs dan 5% cloroxs disertai pembakaranmampu menekan kontaminan yang lebih baik dibandingkan perlakuan yang lain.  Penggunaan media yang ditambahkan 2 ppm 2,4-D menghasilkan induksi kalusbawang merah lokal Palu yang lebih baik dibandingkan dengan perlakuan yang lain.  Penggunaan media tersebut mempercepat pembentukan kalus (25,66 hari setelah kultur) dengan persentase pembentukan kalus mencapai 91,67%.

Abstract

This study aims to determine the influence of some kind of Bokashi on the growth and yield of sweet corn. This research was conducted in the village of Sidera, District of Biromaru, Sigi, Central Sulawesi Province. Analysis of the soil, and Bokashi were conducted in the Laboratory of Soil Science, Faculty of Agriculture, University of Tadulako, Palu. This study used a randomized block design with 7 treatments that werecontrol, Bokashi of gamal 15 t ha-1, Bokashi of johar15 t ha-1, Bokashi of geanust leaf peanuts 15 t ha-1, Bokashi of chicken manure 15 t ha-1, Bokashi goat manure 15 t ha-1, Bokashi of cow manure 15 t ha-1. Each treatment was repeated 3 times so that there are 21 units experiments.Variabel observations were: plant high, stemdiameter ,total leaves , day of flower ins, cob length, diameter cob and sweet corn production (tons ha-1). Data were analyzed using ANOVA test if there are significant then tested further by using advanced test Honestly Significant Difference 5% (HSD 5%). The results showed that the granting of various types of Bokashi provide a significant influence on the growth and yield of sweet corn. Giving Bokashi Johar leaves give better results on the growth of sweet corn plants, while granting Bokashi Gamal leaves give better results against the results of sweet corn production.

Abstract

This study aim was to determine the single and the interaction effect of inorganic fertilizers (NPK) and organic fertilizers (chicken manure) on the nitrogen uptake of shallot in entisols Sidera. This study used a Randomized Block design (RBD), which consisted of 9 treatments and replicated three times so that there were 27 experimental units. The treatments consisted of control and two types of fertilizers. The inorganic fertilizers were added at the rate of 150 and 300 kg ha-1, whereas the organic fertilizers at 10t ha -1 and 40 t ha-1. Data was analyzed using analysis of variance to determine the effect between treatments. If the results of analysis of variance showed a significant effect, then it was tested further using 5% honest significant difference (HSD 5%). The results showed that administration of inorganic fertilizer (NPK) at the rate of 300 kg ha-1 significantly increased the nitrogen uptake of the crops while the chicken manure at the rate of 40 t ha-1 very significantly increased the nitrogen uptake and there was no significant interaction between the inorganic and organic fertilizers (NPK) on the nitrogen uptake of the shallot (Allium ascalonicum L.).

Abstract

This study aimed to determine the effect of  plant number, fertilizers, pesticides, and labor on the production of cacao farming in Masari Village, South Parigi Sub District, Parigi Moutong District. Determination of respondents used a simple random technique.  The analysis tool used was the Cobb-Douglas production function. The analysis shows that the coefficient of determination (R2) was 0.856 indicating that the dependent variable of the cocoa farm production was 85.6% affected by the independent variables tested by the reasearchers, while the remaining 14.4% was affected by other variables outside the model.  The result of F-test showed that number of producing plants (X1), fertilizers (X2), pesticides (X3) and labor (X4) simultaneously had significant effect on the cacao production..  The results of t-test also suggested that individually all independent variables significantly affected the production of the cacao farming in Masari Village, South Parigi Sub District, Parigi Moutong District.

Abstract

The purpose of this study is to analyze financial feasibility and conducting business planning Taro Chips Enterprises. The research was conducted at the home industries KUB "Menggaka" which took place in the village of Porame, District Konivaro, Sigi in May to July 2016. The data used in this study using two types of data, primary data and secondary data. Analysis of the data used is the Net Present Value (NPV), Net Benevit Cost Ratio (Net B / C), Internal Rate of Return (IRR), and Payback Period (PP). Results of the analysis showed that the Net Present Value (NPV) of Rp. 53,652,956 and Rp.33,914,761for data input. This indicates that the positive NPV (NPV> 0), so declared eligible to run. Net Benefit Cost Ratio (Net B / C) obtained a value of 5.2 > 1 and 1.215> 1 for data input. Meaning Net B / C is greater than 1 (one), so that the business is feasible to run. Internal Rate of Return (IRR) obtained amounted to 51 percent and 18,95percent for data input. That is, the industry is eligible to run because the rate of return greater than the interest rate applicable (i = 15%) and (i = 18%), while the result of the calculation Payback Period obtained has a repayment period of 1 year 6 months 10 days and 1 years 5 months 14 days to prediction data. That is, in this period of investment costs incurred will be back, so the faster the payback period of investment costs, the business run better.
