Abstract

Landslide problems often occur in Indonesia, such as in irrigation canals, most are still in the form of land channels, which results in considerable water loss due to many leaks, so that water disputes often occur by farmers during the dry season. The channel wall landslides also impacted the silting of the irrigation channels which resulted in a non-smooth flow of water, the need for irrigation water on the DI Channel. Lumbangsari (252 Ha) cannot meet the water needs in the rice fields. One of the ways used to control the stability of the soil so that it does not slide is to build a retaining wall on the channel. Planning the channel wall located in DI. Lumbangsari (252 Ha), Lumbangsari Village, Bululawang District, Malang Regency. In this evaluation plan, data is taken directly through direct surveys at locations and using maps of soil types. In order for the building to function properly, the stability of the building must also be planned as well as possible, therefore, the stability of the channel wall is analyzed with the danger of rolling (bolting) and gliding under normal water conditions without earthquakes, double earthquakes and flood water conditions without earthquakes , with earthquakes analyzed using Rankine formulas. The result is SFsliding 1.85> 1.5 and 1.85> 1.5, SFbolters 1.64> 1.5 and 1.64> 1.5 (for normal conditions without earthquakes and with earthquakes) and SFsliding 2.05 > 1.5 and 2.03> 1.5, SFbolters 1.67> 1.5 and 1.66> 1.5 (for flood conditions without and with earthquakes), the situation is safe. In this study the budget plan for the cost of the channel wall is Rp. 52,781,008.28.

Abstract

Agricultural land always needs water to maintain its fertility. Water is a source of nutrients and nutrients that act as fertilizers for land and agricultural crops. At this time the land area of the Onggok Atas sub-irrigation area, Banjarcahyana Irrigation Area has not been able to obtain irrigation water evenly in the sense of sufficient quantity and the right time. This is due to, among other things, the condition of the irrigation network has decreased its capacity. This study aims to determine the need for irrigation water in rice fields, to determine the need for water in the channel and to determine the dimensions of the Onggok Atas secondary channel. Researchers conducted a review of secondary channels by collecting secondary data for the calculation of hydrological analysis, irrigation water needs using KP 01 and 03 guidebooks and later obtained the cross-sectional size of secondary irrigation channels. Based on the results of the analysis that has been calculated on an area of 316.10ha and the length of the secondary channel is 4881m, the irrigation water requirement in rice fields is 1.11lt/dt/ha for rice and 0.89lt/dt/ha for secondary crops. The water requirement upstream is 488.25lt/dt = 0.488m3/dt and the water requirement downstream is 100.67lt/dt = 0.101m3/dt. The dimensions of the largest irrigation secondary channel are B.OA 1, Stream Cross Section, (A) = 0.919m2 with width (b) = 0.95m and height (H) = 0.79m, and the dimensions of the smallest irrigation secondary channel are B.OA 6, Stream Cross Section, (A) = 0.171m2 with width (b) = 0.45m and height (H) = 0.45m.

Abstract

This research aims to examine the effect of giving rewards on students' learning motivation in social studies learning in class VI SDIT BPMAA. The research method used is quantitative with an experimental design. The research subjects were class V students at SDIT BPMAA, consisting of two groups. Data was collected through learning motivation questionnaires and learning outcomes tests which included social studies material. Data analysis was carried out using the Wilcoxon test to compare the level of learning motivation between the experimental group and the control group. The results of the study showed that there was a significant difference in motivation to learn social studies between students who were given rewards and those who were not. Students who were given rewards showed a significant increase in their learning motivation compared to students who were not given rewards. By looking at the results of the SPSS test which uses the Wilcoxon test, where the sig value is smaller than the value 0.005 or 0.00 < 0.05, it can be said that reard training is very influential in increasing students' learning motivation abilities. The conclusion of this research is that giving rewards has a positive influence on the learning motivation and social studies learning outcomes of class V students at SDIT BPMAA. Therefore, the strategy of giving rewards can be considered as a method to increase student motivation and learning outcomes in social studies subjects, written in a maximum of 250 words describing the problem, research objectives, methodology and results obtained.

Abstract

This research aims to analyze the stability of the Kambaniru Dam which is located in the Luku Kambaniru River, East Sumba Regency, East Nusa Tenggara Province. In this research, a preparatory stage was carried out which included literature study and field observations to collect weir design data and soil mechanics data. The data is then analyzed using an appropriate formula to evaluate the stability of the weir. The results of the data analysis were used to prepare a final report examining the performance of Kambaniru Dam stability planning. The calculation results show that the weir with the planned dimensions, namely 7.00 m high and 69.40 m wide, equipped with a 30 m long energy absorber, meets high safety standards. Stability analysis shows that the safety value (Sf) in terms of overturning force, shear force and soil bearing capacity under normal and flood conditions (with and without an earthquake) exceeds 1.5, indicating that this weir is in a safe condition. Therefore, the construction of the Kambaniru Dam according to the planned dimensions is considered reliable and safe.

Abstract

The frequent occurrence of landslides in the Ngantang District, Malang Regency, especially in Ngantru Village, is caused by topographic conditions, where the area is hilly because it is located at the foot of Mount Kelud. Likewise, along the Banu Irrigation Area Channel there are points prone to landslides, especially in the upstream part. These landslides result in the channel breaking so that the irrigation water supply is disrupted. DPT (Soil Retaining Wall) is a building structure whose role is to maintain the stability of the soil on sloping land. The existence of this wall is expected to be able to prevent the soil from moving or landslides. Therefore, to protect the Banu Irrigation Area Channel, a DPT construction was built where the DPT details used were stone masonry construction or the Gravity Wall type. With a total height of 3.9 m, the bottom sole width is 1.00 m and the upper sole width is 0.50 m. The purpose of this paper is to analyze whether the existing DPT is safe  against the forces that work, especially analyzing its stability, then comparing it with other DPT designs with the Cantilever Wall type. Based on the analysis of calculations for the Existing Gravity Type Earth Retaining Wall, the stability figures for soil bearing capacity σ max= 23.76 > 15.012 (safe ), stability against sliding hazards Fgs=3.321 ≥ 1.5 (safe ), and stability against sliding hazards Fgs=3.321 ≥ 1.5 (safe ) are obtained. = 6.26 > 1.5 (safe ) while for cost calculations the value obtained is IDR 180,390,000.00 (One Hundred and Eighty Million Three Hundred and Ninety Thousand Rupiah). Meanwhile, for the analysis of the comparative soil retaining wall for the cantilever type, the stability figures for soil bearing capacity σ max= 25.92 > 15.012 (safe), stability against sliding hazards Fgs=3.55 ≥ 1.5 (safe ), and stability against overturning hazards were obtained. SF= 6.64 > 1.5 (safe ).
