A field study was carried out to assess the effects of mixed cultivar plantings on grain yields and on the abundance of pests in rice. Increasing plantation species diversity through cultivar mixtures is often claimed to decrease pest problems while stabilizing or even increasing yield, but the effects on pest abundance of planting rice cultivar mixtures in Indonesia have not been extensively studied. We tested for changes in pest abundance in experimental plots planted with five genetically distinct rice cultivars, combined in two different mixture arrangements (seed mix and row mix). These mixes were cultivated in lowland paddy areas, in replicated randomized block designs, during two growing seasons. Pest abundance was measured weekly in all plots, and rice yields were measured at harvest time. The results showed that the average abundance of pests was reduced in plots planted with cultivar mixes, compared to those planted with monocrops comprised of each of the component cultivars. Plots planted with the seed mix showed consistently reduced brown plant-hopper (Nilaparvata lugens (Stål)) abundance compared to monocrops in each growing season, with a relative reduction in pest abundance of 29.83% at the end of season 1 and 6.61% at the end of season 2, respectively. Plots planted with the row mix consistently showed decreased stem borer abundance compared to monocrops in each growing season, with a relative reduction in pest abundance of 100% at the end of season 1 and 1.4% at the end of season 2, respectively. In terms of yield, plant height proved to be a consistent yield component character, correlating positively with plant yield for both seed mix and row mix in both growing seasons. Our results showed higher average yields –and plant heights--for the mixed genotype plots compared to pure genotype stands in 2013. We found a greater relative increase in the yield of seed mix plots than row mix, measuring 7.26% and 4.63%, respectively in 2013. Among the two types of mixtures, seed mix showed higher overall grain yield. Our findings suggest that rice farmers can both increase yield and decrease pest abundance by planting cultivar mixes.

Joint beam-columns are the main structural components that function to support other structural loads. The beam-column relationship area is a critical area that needs to be designed to be truly accurate so that it can dissipate energy properly well in the event of an earthquake happen. As a structural component with the role and function, column joint beams occupy important positions in the building. The ability of column joint beams to deform cyclic loads in the inelastic region provides a good structure, so as to minimize damage caused by earthquake shaking. The failure of column joint beams directly affects other structural components associated with it. The purpose of this study was to study the ability of building structures on concrete column beam joint elements to resist cyclic load with reinforcement reinforcement in accordance with SK SNI T-15-1991. Test specimens amounted to 1 (one) with a concrete quality of 19.17 MPa. The beam measuring 120 x 30 x 40 cm, column measuring 30 x 30 x 200 cm using reinforcement 8, 13.4 mm with a melting voltage (fy) 310,03 MPa and stirrup reinforcement Ø9.8-100 mm with melting stress (fy) 374,59 MPa. The test was carried out by giving a cyclic load to the end of the beam with 0.75 mm, 1.5 mm, 3 mm, 6 mm, 12 mm, 24 mm and monotonic loading, until the specimen was destroyed. The results achieved in this study are the use of reinforcement reinforcement according to SK SNI T-15-1991-03 the capacity of the cyclic load produced is higher, namely 6,97 tf (press) and 5.09 tf (tensile).

Water stress is one of factors which causes low yield of lowland. This study aimed to identify and characterize morphology and physiology of drought tolerant rice varieties. Experiments which have conducted: (i) Investigation of rice varieties tolerance to drought stress at early vegetative stage in the laboratory (ii) morphology and physiology characters of rice varieties to drought stress in the paddy field and (iii) determining the character of root of rice tolerant to drought stress. The experimental design used was split plot design with 3 (three) replications, with drought stress as the main plot and the variety as sub-plot. The result of screening test at the laboratory using PEG (Polyethylene Glycol) which could characterize which rice varieties could be considered as drought tolerant varieties. Results showed that periods of drought increasing the proline content at Ciherang (25.38 μmol) and IPB 3S varieties (22.08 μmol) at 13 WAT (Week After Transplanting). The variety that has the highest total sugar content in the flowering stage is Rokan (289.38 mg.g-1DW) followed by Menthik Wangi (230.53 mg.g1DW), while the lowest sugar content in harvest found in Jatiluhur (17.14 mg.g-1DW) followed by Way Apo Buru (46.99 mg.g-1DW). Jatiluhur, Way Apo Buru and IPB 3S varieties have drought tolerant based on the root characteristic. Ciherang, IPB 3S, Way Apo Buru and Jatiluhur varieties were drought tolerant and potential to be used in paddy field.

Hyperactive teens on social media who try to keep up with the times. Many parents do not care or even let their children use social media according to their children's wishes without parental supervision. Anticipating this problem, the role of parents is very important in overcoming the negative impact of social media on adolescent behavior, where parents have the task of fulfilling children's thinking with positive things that are in accordance with Islamic teachings in building good mindsets for children. Parents are also tasked with providing supervision of children's social media so that children use social media wisely. The purpose of this study was to determine the role of parents in anticipating the negative impact of social media, the negative impact of social media on adolescent behavior in the X neighborhood of Sumber Karya Village, East Binjai District, Binjai City and parents' efforts to anticipate the negative impact of social media on adolescent behavior in X Sumber Karya Village, East Binjai District, Binjai City. The research location is the X neighborhood of Sumber Karya Village, East Binjai District, Binjai City. This research includes field research (field research) with a descriptive qualitative approach. The results showed that: The role of parents in anticipating the negative impacts of social media: acting as educators, directors and supervisors. The negative impact of social media on adolescent behavior is that teenagers always want to be considered cool in social media, prefer to communicate using social media rather than communicate directly and affect adolescent health. Parents' efforts to anticipate the negative impacts of social media: always provide advice about the negative impacts of social media, provide supervision and provide limits on the use of social media Keyword: The Role Of Parents, The Negative Impact Of Social Media, Adolescent Behavior
