The results of the flexible pavement analysis on Jalan Gulang-Gulang Dusun Koto, Sawahlunto City are based on Component Analysis Method SKBI-2.3.26.1987 are Surface Course (Laston MS 744) 6 cm thick, Base Course (Batu Broken class A) 20 cm thick, Sub base Course (Sirtu Class A) 25 cm thick, while the rigid pavement "AASHTO 1993 method" is a concrete pavement with a thickness of 30 cm and a thin concrete foundation layer (LC) with a thickness of 10 cm. The analysis uses continuous concrete pavement with reinforcement with a plate thickness of 30 cm using shoulders and using D10-20 cm reinforcement for longitudinal and transverse directions. The dowel is installed with D-36 reinforcement with a length of 45 cm, a distance of 30 cm, while the tie bar is installed with D-16 BJTU-24 threaded steel reinforcement with a length of 30 cm. while the tie bar is installed with D-16 BJTU-24 threaded steel reinforcement with a length of 700 mm and a distance of 75 cm. The cost of rigid pavement construction is Rp. 3,039,054,000, - with skinny concrete (LC) specifications of K-175 kg/cm2 and cement concrete layer of K-250 kg/cm2, flexible pavement is Rp.2,910,136,000. shows that flexible pavement can save costs of Rp.128,918,000. With a percentage of 4.24% of the cost of rigid pavement construction. From the results of the comparison of the cost of flexible pavement construction which is cheaper and saves costs

The conservation law states that the cumulative of a quantity in a closed system will stay remain unless there is an inflow or outflow that goes through the boundary area of the system. The law models a consevative phenomena from variety physical quantity that exist in nature. This study is an analysis of descriptive studies on the discontinuities propagation that arise in the nonlinear scalar conservation law with discontinuation initial value problem, also known as the Riemann problem, which is done using characteristic methods. As discontinuity shows, discontinue solution concept from conservation law is introduced , which is referred to as a weak solution.

This research was conducted to increase the selling value of kuini, because kuini is a fruit that is quite popular with the public because of the combination of sweet and sour taste in kuini, but kuini has a low shelf life because it is easily rotten caused by pests. The existence of kuini is abundant at the time of large harvest, but it is not accompanied by absorption in the market, causing losses at the level of kuini farmers. Therefore, it is necessary to process the kuini into a form of diversification of food products so that it can compete in the market and be able to increase the economic value of the kuini. This study aims to determine the effect of adding carrageenan to the total acid of the kuini juice jelly drink. The design used in this study was a completely randomized design (CRD) with 5 different treatments. Observational data were analyzed by means of variance (ANOVA) if significantly different, the DNMRT (Duncan New Multiple Range Test) test was carried out at a 5% significance level. The treatment of this research is the difference in the addition of carrageenan. The five treatments were A (Additional Carrageenan 0.2%), B (Add Carrageenan 0.4%), C (Add Carrageenan 0.6%) D (Add Carrageenan 0.8%), E (Add Carrageenan 1.0 %). The results showed that the addition of carrageenan had no significant effect on the total acidity of the kuini juice jelly drink.

Reinforced concrete structure is a structural forming material that is still widely used. Concrete structure has advantages in the ease of materials and also the workmanship. Reinforced concrete is also more effectively used for structures that have a less long span. Ibis Padang Hotel building planning uses reinforced concrete structures with reference to SNI 2847:2013 on Structural Concrete Requirements for Buildings and SNI 1726:2012 on Earthquake Resilience Planning Procedures for Building And Non-Building Structures. The burdens that occurred were reviewed in SNI 1727:2013 on The Indonesian Demolition Regulation for Buildings and Other Buildings. This planning uses a dual system of SRPMK and sliding walls in terms of earthquake anchoring. The concept of this plan is based on the ultimate design that occurs, where the ultimate value must be smaller than the cross-sectional strength of the structural components. Style calculation â€“ style in using the ETABS 2013 program. In addition, there is also a calculation of the Cost Budget Plan. This writing aims to find out the comparison of the structural components of the Ibis Padang Hotel building using Base Isolator with the results of planning using Fixed Base. The beam component comparison obtained a smaller yield of 15.17% for casting volume and 23.64% for repeat weight. The comparison of column components obtained smaller results of 29.17% for casting volume and 24.32% for repeat weight. Comparison of plate components obtained a smaller result of 16.58% for the repeating weight. The comparison of pile cap components obtained a smaller result of 45.98% for casting volume and 2.54% of repeating weight.

Seeing the importance of an information managed by the kelurahan part, which called as the community who cares about garbage where it is very difficult for people to get information about waste in the Ratu Sima subdistrict. To address this, a website must be created that is both effective and capable of assisting in the management of garbage and information from the Ratu Sima Village. The website was created using the CodeIgniter 3 framework with MySQLI as the database management system. To test how the website works, this system is examined using the black box method. The website was successfully developed according to the concept, and all functionalities can run effectively, as evidenced by the results of the User Acceptance Test (UAT), which scored "Very Good" with an 87 percent score.

This study aims to determine the optimal inventory control of cardboard raw materials at CV. Multirejeki Selaras, a Bottled Drinking Water company in 2020 using the Economic Order Quantity method. The research was conducted using quantitative descriptive methods by describing how the company controls inventory and then the data obtained were analyzed using the EOQ method. The results showed that the cardboard raw material inventory control was implemented by CV. Multirejeki Selaras is not yet optimal. This can be seen from the resulting TIC value whereby using the EOQ method the company can make savings of 53%. By using the EOQ method, the optimal number of cardboard purchases is 129,839 units with a frequency of ordering 13 times a year. The number of safety supplies that must be available in the company is 15,457 units. The re-order point for purchasing boxes is when the available boxes are 38,657 units.

Momordica charantia L. contain alkaloid, flavonoid, phenolic, tannin and saponin compounds which can protect the gastric mucosa. This study aims to determine the effect of giving the ethanol extract of bitter melon leaves (Momordica charantia L.) on the protective activity of the gastric mucosa in aspirin-induced male white rats. Momordica charantia L maceration using 70% ethanol as a solvent. The gastric mucosal protective activity test used 15 male white rats which were divided into 5 groups. The treatments were given orally for 3 days including: the positive control group was given 0.5% Na-CMC + aspirin 600 mg/kgBB, the comparison control group was given sucralfate suspension 360 mg/kgBB + aspirin 600 mg/kgBB, the test dose group 1 was given Pare leaf ethanol extract 100 mg/kgBB + aspirin 600 mg/kgBB, group 2 test dose was given ethanol extract of bitter melon leaves 200 mg/kgBB + aspirin 600 mg/kgBB and group 3 test dose was given ethanol extract of bitter melon leaves 400 mg/kgBB + aspirin 600 mg/kgBB. On day 3, the mice were dissected after 4 hours of aspirin administration, observation and the percentage of gastric mucosal protection in the rats was calculated. Data were analyzed statistically with one-way ANOVA test followed by Duncan's test. The bitter melon leaf extract had a significant effect (p <0.05) on the protection of the gastric mucosa. The highest percentage of protection was shown by the dose of 400 mg / kgBW at 62.48%.
