Abstract

The high number of losses and casualties experienced by the Indonesian people is caused by various factors. One of the factors lies in the people who lack knowledge in dealing with climate phenomena. Student-teacher candidates must take an important role in solving climate problems. One solution is to predict climate phenomena. This study uses the ARIMA model to predict the El Niño La Niña & Indian Ocean Dipole phenomenon. The research method is the ARIMA model prediction steps using student worksheets. (1) know the model by determining ACF and PACF. (2) parameter model estimation determines ARIMA on predetermined ACF and PACF. The ARIMA parameter model is the slightest Mean Squared Error (MSE) level. (3) the diagnostic model of the smallest MSE. (4) a measure of predictive accuracy. And (5) Argumentation. Results In the IOD calculation, the correlation between the three-month prediction period is 0.92 and for six months is 0.96. This is the same as in the Nińo 3.4 correlation data. The value is close to 1, which is very accurate and can be used. The predicted value of the IOD index was expected. The resulting values ​​ranged from 0.01 to 0.17. This means that students are proficient in making climate predictions. Because students are enthusiastic and passionate about studying climate, it is a new science

Abstract

This study used waste coconut fibre and HDPE plastic as partial aggregate replacement materials. Coconut fibre ash has pozzolanic properties, which contain high silicate elements. High-density polyethene (HDPE) plastic has more potent, complex, opaque material properties and is more resistant to high temperatures. Superplasticizer is an admixture added to concrete during mixing and during placing to improve its strength performance. This study aims to study the effect of adding HDPE plastic as a substitute for coarse aggregate, coconut fibre ash as a substitute for fine aggregate and Viscrocrete-8670 MN on absorption, concrete compressive strength and elastic modulus of concrete. With variations in the addition of BN HDPE plastic, 0.5%, 1%, and 1.5%, the coarse aggregate passed 3/8 filter retained by filter no 4, 3% coconut fibre ash for each variation of concrete and Viscrocrete-8670 MN by 0.8% by weight of cement. The maximum value for each concrete test is the absorption value of concrete (4.23% for regular concrete), compressive strength (32.49 MPa for 1.5% HDPE concrete), and the modulus of elasticity (3152 MPa for 1.5% HDPE concrete).

Abstract

This study aims to determine the types of weeds that can be controlled or destroyed using the chemical Gempur 480 SL at PT. Toba Pulp Lestari Estate Tele. The method used in this research is a field survey method at 3 different masl by means of purposive sampling. Based on the research that has been done, it shows that the treatment of weed types found in Estate Tele is dominated by sedge weeds such as Cyperus rotundus and broad leaf weeds such as Boreria latifolia, Climedia hirta and Melastoma malabathtricum, while narrow leaf weeds such as Petridium (elephant fern), Stenochlaena (Vegetable ferns), Dicranopteris linearis (Wire ferns) are relatively few compared to sedge weeds and broadleaf weeds. The use of the concentration of the hebicide Gempur 480 SL of 1.25% can suppress weed growth where the percentage of dead weeds is higher. Weeding rounds have a significant effect on the percentage of weeds that die and the percentage of weeds that don't die. The highest percentage of weeds that died was in Weeding Round 3 (WR3). The interaction of herbicide concentrations and weeding rounds had a significant effect on the percentage of live weeds and the percentage of weeds that were not alive. The increase in the percentage of dead weeds will increase with the increasing concentration of the herbicide Gempur 480 SL, especially if the increased concentration of the herbicide Gempur is combined with Weeding Round 2 (WR2).

Abstract

Alstonia sp leaves extract has previously been reported as a potential antimalarial drug as traditional. This study aims to analyze the antimalarial activity and determine the antioxidant potential of titi tree leaves (Alstonia sp). The method used in this research is a modified method of "4 Days Suppressive Test" which was originally described by Peter with different doses (0.55 g/kg, 0.65 g/kg and 0.75 g/kg body weight) of methanol extract of leaves of Titi tree (Alstonia sp) was administered orally to albino mice. Antioxidants were analyzed using a spectrophotometer. The Leaves of Alstonia sp has antimalarial activity and contains potential antioxidant activity with an IC50 value of 70.12 ppm for leaves (strong category). The dose of 0.75 g has a better effect compared to the other effects because it lowers the level of parasitemia more strongly. So that the leaves of Alstonia sp. pressured to be developed as a nutraceutical.
