The planning of the air system is intended to calculate the cooling load in the Hall of SMKN 1 Sekayu. So that before the AC was installed in the SMKN 1 Sekayu had an overview of the amount of AC capacity needed to condition the air in the hall with dimensions of 18 m x 16 m x 6 m. To obtain these results, the authors used the CLTD (Cooling Load Temperature Difference) calculation method based on ASHRAE GRP 158 Cooling Load Calculation Manual. Which consists of calculation of Extenal and Internal cooling loads. Calculation of cooling load based on primary and secondary data which then results are adjusted to the type of air system. After calculating the cooling load, the maximum load results are obtained at 237013,1917 Btu / hr, thus the AC capacity needed is 26 Pk with the Direct Refrigerant System, AC Floor Standing system.

Buffer solution is one of the lessons that are considered difficult by students. This is because in learning the buffer solution has a lot of prior knowledge, which must be understood by students in order to understand the buffer solution. This research means to analyze the relationship of prior knowledge with students' learning difficult in learning buffer solutions in SMA N 1Solok. This research is a descriptive study conducted on class XI students of SMA N 1 Solok. The research subjects were 47 students. Data analysis techniques are carried out quantitative means at determining the percentage of students' learning difficulties in learning buffer solutions and the percentage of learning difficulties in the prior knowledge. From the research found the percentage of students experiencing learning difficulties with a very high category, namely the subject matter of the capacity of the buffer solution 92.3% and the pH of the buffer solution 83%, then the percentage with a high category on the subject matter of the mechanism of the buffer solution is 74.5%, and the moderate category in the material the properties of the buffer solution is 65.3%.  Learning difficulties by students are caused students do not understand the prior knowledge which is a prerequisite for learning buffer solutions in the form of chemical equilibrium, equilibrium constants, Brownsted-Lowry acid base concepts and acid base stoichiometry.   Keyword:  Prior Knowledge, Learning Difficulties, Buffer Solution

The total flavonoid content in salam leaves has an anti-inflammatory activity at a dose of 2.1% w/w. For topical anti-inflammatory, a matrix patch has a delivery mechanism that drugs pass through in the skin in a controlled for an extended period. Polymers were the patch's main component to control the drug release. Polyvinyl alcohol (PVA) and alpha-cellulose (AC) were polymers that can increase the rate of drug diffusion and form a strong film layer. Salam leaves were extracted by maceration using ethanol 96%. Matrix patches were made with a combination of PVA and AC in ratios 1:1; 3:1; 1:3. The patches were tested for physicochemical properties. The stability test was conducted at 4, 25, and 40 temperatures for 8 h, respectively. Statistical analysis of the test data used One Way ANOVA with a confidence level of 95%. The results showed that the high concentration of PVA significantly affected the weight and moisture content but did not affect the organoleptic thickness, folding endurance, and pH of the matrix patch. The best matrix patch of salam leaves ethanolic extract was PVA and AC of 3:1 because it met the requirements for the matrix patch, including the weight of 1.96-2.06 grams, thickness of 1.15-1.18 mm, folding endurance >300 times, humidity 25.75 – 30.17% and pH 6.3 – 7.1. The patch contains flavonoids with Rf values for extract and patch of 0.95 and 0.96, respectively. Further study, in vivo anti-inflammatory test is necessary.

Background: The main factor in a restaurant that must always be maintained is the hygiene and sanitation of the restaurant. Based on the results of observations in several restaurants in the working area of the Lampulo Community Health Center,it can be seen that the sanitation of restaurants does not meet standards, such as the condition of the equipment washing facilities that are not suitable for use, the absence of special trash cans, the absence of covers for prepared food and the absence of facilities for prevention fly. This research aims to determine the relationship between basic sanitation and the level of fly density at restaurants in the Lampulo Community Health Center Working Area, Kota Banda Aceh in 2021. Method: The research is descriptive analytical with a cross- sectional design. Sampling was taken using a total sampling method of of 50 restaurants. Data analysis used the Chi Square test with the STATA 13 computer program. Results: The results showed that 55.8% of restaurants had a high fly density level. The results of the bivariate analysis show that there is a relationship between ready-made food storage places (p value = 0.019), equipment washing places (p value= 0.013), rubbish disposal places (p value= 0.003), and fly prevention facilities (p value= 0.001). Recommendation: Restaurant owners to improve sanitation facilities in restaurants, maintain environmental cleanliness, and implement health requirements in restaurants.

Balancing Funds from cen tral to specific regions in Central Java Province contributed from the balancing fund from the Year 2013-2016 on average by 98.36% while for the Revenue Only 90.37%. This indicates that local governments are still dependent on the central government. Local governments need to optimize the source of revenues sourced from the Local Revenue. Special Government of Central Java Province is regulated in Local Regulation number 2 Year 2011 on Central Java Province Tax and has been referring to Law Number 28 Year 2009 on Regional Tax and Retribution. This study aims to determine and analyze the extent of the existence of local tax arrangements in increasing local revenue in Central Java Province for the fiscal year 2013-2016. Data analysis method used is juridical empirical. The results of this study indicate that simultaneously there is the influence of Local Taxes on Local Revenue of 90% and fragmentary Local Tax positively substantially influential on Local Revenue have a significant effect positively on the Original Revenue.Keywords: Existence, Local Tax, Local Original Income

Writing skills are one of the essential components in mastering a language, apart from other linguistic skills. Writing demands a profound understanding of language structure, particularly grammar. The current junior high school (SMP) curriculum integrates grammar materials into various learning modules, often causing students to be unaware that they are learning grammatical concepts. This development research aims to design an effective grammar learning module, with the hope to (1) facilitate students' understanding of grammatical concepts, (2) enhance student's writing skills with an emphasis on grammatical aspects, (3) assess the suitability of the learning module with the writing learning needs at the junior high school level, and (4) obtain feedback from educators and students regarding the implementation of the module in schools in Bekasi City. This research adopts the Research and Development (R&D) model following the 4-D model stages: definition, design, development, and dissemination. Data collection was conducted through interviews and questionnaires. Experts in content, media, and language performed module validation. The research results indicate that the implementation of the grammar learning module can have a positive impact on improving students' writing skills, as reflected in the increased writing test scores.
