Healthy behaviour is a proactive attitude to maintain and improve health, prevent the risk of disease, protect yourself from disease threats and play an active role in public health movement activities. One of the healthy attitudes that must be created is the attitude of prevention and disease management with immunization activities. This research aims to analyse the relationship level of education, knowledge and attitude of baby mothers with the completeness of basic immunization in the work area of Puskesmas Lemo Teweh District of North Barito Regency. The method used is an analytical survey with a Cross Sectional approach aimed at knowing the relationship level of education, knowledge, attitude with immunization in the baby. The result is a relationship between knowledge and attitude with the completeness of immunization in infants, completeness of basic immunization in infants 48.4% (31 babies). To increase the percentage of completeness of basic immunization in Lemo Puskesmas is by improving the extension, especially about the benefits and schedule of immunization administration.

The use of electric current will be related to heat input. Enough heat input is needed to form a good nugget structure so that it can produce maximum connection strength. The nugget structure is influenced by electrode pressure, holding time and the electric current used. By adjusting the parameters of the amount of electric current, the best connection quality will be produced. The purpose of this study is to determine the effect of variations in electric current on the shear tensile strength of dissimilar welding Stainless steel (SS) and Aluminum (Al). The variation of electric current used is 60 A, 70 A and 80 A. The welding time used is 4 seconds. The test material uses stainless steel material with a thickness of 1.2 mm and aluminum with a thickness of 0.9 mm. This research was conducted at the Kotabaru Polytechnic Mechanical Laboratory and Malang State Polytechnic Material Test Laboratory. Tests carried out are shear tensile tests according to ASME (American Society of Mechanical Engineering) standards. The results showed that an increase in electric current from 60 A to 70 A had an impact on the increase in shear tensile strength. While the increase in electric current from 70 A to 80 A shows a decrease in shear tensile strength. The results of shear tensile testing indicate that the best conditions occur at 70 A electric current which gives a shear tensile strength of 44.109 kN / mm2. The increase in the electric current at the dissimilar welding between Stainless Steel and Aluminum is not directly proportional to the increase in shear stress that occurs. This is because the melting point of each material is different. If the heat generated exceeds the melting point of the material used, the welding results will be damaged.

Exploring information or new knowledge from existing data sets is an important point of the data mining process, such as a collection of course value data that has been stored, but its potential has not been raised to find new benefits. While on the other hand there is the problem of how to find the concentration of studies that are in accordance with the competencies of the students themselves. This study was conducted to find the concentration selection pattern, based on some of the best value data from the courses that have been taken using the Apriori Algorithma, where the rules in this method will be used to find the pattern in question. Using a minimum support value of 70% produces rules with 5 item sets, namely courses in logic and algorithms, system analysis, system design, web programming and software engineering. The pattern / rule produced can be a guide for students in choosing concentration.

Serunai (Chromolaena odorata L.) is a medicinal plant, including the Asteraceae family. Serunai is used to treat wounds, mouthwash to treat sore throats, coughs, malaria drugs, headache medications, antidiarrheals, antimicrobials, antispasmodics, antihypertensive, anti-inflammatory and diuretic agents. Serunai plants contain chemical compounds tannins, phenols, flavonoids, saponins and steroids. The purpose of this study was to determine the total phenolic content of the leaves of serunai using the UV-Vis spectrophotometric method. The stages of the research include plant determination, sampling, making of simplicia leaf of serunai, making extract by maceration method, phenolic compound test, determination of total phenolic levels by UV-Vis spectrophotometry with Folin-Ciocalteu reagent, comparing gallic acid. The results obtained by an average of total phenolic levels of ethanol extract of serunai is 171.30368 ± 1.9694 mg GAE / g means that in every gram of ethanol extract of flattened leaves is equivalent to 171,30368 mg gallic acid.

Geoelectric resistivity method is one method that can be used to characterize water-bearing rock layers (aquifers). This method is based on the existence of differences in type resistivity in the layers of rock that are flowed electrically. The use of this method is based on easy application, faster data acquisition with broad data coverage (lateral and vertical), and lower costs. Data acquisition uses two configurations or electrode arrangement, namely sclumberger and wenner-schlumberger configurations. The number of trajectories for data acquisition uses one path with a total of 28 electrodes and the spacing between the electrodes is 20 meters. The data obtained in the form of data resistivity type of each underground layer and its depth will be further analyzed using AGISSAdmin software. The results are obtained in the form of a 2-dimensional (2D) cross-sectional value of underground layers laterally and vertically. The low resistivity value will be interpreted as a layer containing ground water, which was previously corrected against the geological and hydrological data of the area. From the cross section of the type resistors, values of 20 - 317 Ωm were obtained for the wenner and wenner-schlumberger arrangements. Selaru Village consists of two rocks unit, the first rock (≤ 120 Ohm.m) in the form of Tanjung Formation rocks, with large porosity and small permeability and groundwater potential in this unit is small (0 - 40 m depth). The second rock (≥ 120 Ohm.m) is Pre Tertiary, with very little porosity and permeability, except secondary porosity in rock fractures.

Ammonia which is bound to the adsorbent can interfere adsorption process, so that release the compound can be done by desorption process. This research intends to know appropriate equilibrium models to determine maximum capacity of active carbon for desorption ammonia. The method which used in desorption process are Langmuir and Freundlich isotherm models. The research was performed with variation of active carbon mass and variation of contact time. The concentration of ammonia on the desorption process was determined using spectrophotometer at λ 420 nm. The experiment result showed that the more the active carbon dosage is used, the more the concentration of ammonia is increased. Optimum contact time during 7 hours with desorption percentage 94-96%. This research of ammonia desorption by active carbon followed the Langmuir equilibrium model R2 0.954 and Freundlich equilibrium model R2 0.952. The equilibrium equation is used Langmuir equation y = -0.015x + 3.185, maximum desorption capacity is 66.67 mg/g.

The purpose of this study was to determine the optimum absorption time of corn cob charcoal in absorbing Fe (II) ions, and the effect of pH of the solution on Fe concentration was absorbed in batch isothermic conditions using the Langmuir equation. The study was carried out under atmospheric conditions, temperature 27oC. A total of 0.6 g of char is added to 50 ml of Fe solution with various concentrations and then stirred using a magnetic stirrer at a speed of 150 rpm. Equilibrium data is taken after the process last for 24 hours, while to determine the contact time is selected at 5, 10, 15, 20, and 25 minutes. The optimum absorption time of corn cob charcoal in absorbing Fe (II) ions is 20 minutes. The amount of Fe absorbed increases with increasing pH.
