The Kendal Industrial Area (KIK) is developed to accelerate economic development in the Kendal district area and to support the acceleration and expansion of economic development. Industrialization will lead to a process of air pollution which is marked by 16 companies that are already operating in the KIK area. This research was aimed to analyze the impact of the Kendal Industrial Estate on air quality. The approach of this research used descriptive method, with an analysis of changes in air quality that occurred before the existence of KIK and after the development of industrial areas. The factors that affect the air quality conditions reviewed in this study were air temperature, surface pressure, wind speed, and relative humidity. Data collection techniques used were secondary data NASA satellite imagery. The results showed that there is a change in air conditions after the presence of KIK as indicated by the increase in air pressure and air temperature and the decrease in relative humidity and wind speed. The results indicates that the existence of the Kendal Industrial Area (KIK) causes changes in environmental conditions, but these changes are not significant so they are still within the comfort limits for industrial areas.

According to the HDI, science education in Indonesia has a low number in producing students with independence, creativity, and critical thinking. In fulfilling and improving these criteria, the use of media learning based on Android, HTML, and offline-accessible applications has been enforced. The purpose of this research is to examine the need for developing learning media aiming to increase students' independence, creativity, and critical thinking. Descriptive narrative survey research is used as the method to employ the instrument indicators, including independence, creativity, and critical thinking. The instrument indicators consist of learning process, the need for electronic materials and supporting facilities and infrastructure. This study was conducted on 40 teachers, 3 male and 37 female, at SMK Pusat Keunggulan and 125 students, two females and 123 males, at SMKN 1 Trenggalek, two female and 123 male students. The survey on the students is also conducted to acknowledge and measure the indicators, including independence, creativity, and critical thinking. Data analysis is carried out through the validation of the instrument as the first step. After being revised, the implementation of the instrument was then conducted. Following the steps, the data were analyzed by applying Likert analysis. Based on the data obtained, 88% of the students and 100% of the teachers required innovative, intriguing, and accessible electronic-based materials to support and enhance both comprehensions of the lessons. Students who are categorized as less independent have 83.25% independency, 68.25%, and 83% critical thinking in average. As a result, learning media that are accessible offline, based on Android, HTML, and applications, are required.

Boron Neutron Capture Therapy (BNCT) is a relatively safer technology for killing cancer cells, one of which is the Glioblastoma multiforme. One of the main components of the BNCT equipment is the collimator which functions as an exit point for epithermal neutron particles that hit cancer cells. In addition to the experimental method, BNCT research can be carried out by modeling, including using the MCNPX software based on the Monte Carlo Method. This research aimed to determine the flux distribution of fast and epithermal neutrons and the dose rate of fast neutrons and gamma that hit the target cancer cells in the phantom head of ORNL MIRD. Modeling using the MCNPX software has three main parts: cell cards, surface cards, and data cards. A tally is used on the data card to calculate the neutron flux. Based on the calculation of the modeling results, the flux of epithermal neutron is 2.87 x 109 n/cm2.s. The dose ratio of the epithermal to the fast neutron flux is 2.29 x 10-14 Gy.cm2/n. Then, the balance of the dose rate of the epithermal to the gamma is 1.64 x 10-14 Gy.cm2/n, and the ratio of epithermal to thermal neutron flux is 0.004. In this study, the epithermal neutron flux hitting the target cancer cells in cell target was moderated at 4 cm so that at a depth of 8 cm, the energy was converted into thermal neutrons. Based on the analysis of the results, it can be concluded that the neutron flux that will interact with cancer tissue is thermal neutrons, not epithermal neutron flux.

The development of education needs to adapt to the needs of 21st century skills, including collaboration and problem solving. This study aims to analyze and describe the profile of Collaborative Problem Solving (CPS) online learning, as well as to describe the problem solving skills after learning. This research was conducted at SMA N 1 Gubug in class XI MIPA 1 for the academic year 2021/2022 with a qualitative descriptive method. CPS online learning is divided into virtual meetings using Microsoft Teams and discussions via text messages in WhatsApp. The research data was obtained through data observation’s, interviews, and written posttests. Data processing using a fixed comparison method with three stages, namely; data reduction, categorization, synthesis, and determination of hypotheses. The results showed that the role of the teacher appeared with almost the same frequency, namely as a motivator (37%), communicator (32%) and facilitator (31%). Students' problem-solving skills are dominated by the ability to plan and identify problems with the frequency of occurrence of 35% and 31%, respectively. The next two stages of problem solving, namely implementing the plan and checking back only appeared with a percentage of 19% and 15%.

The purpose of this research was to examine the value of the Wien’s constant using PhET Simulation virtual laboratory and simple numerical approach. The independent and dependent variable is blackbody temperature (T) and maximum wavelength (λ_max). In the use of a virtual laboratory, research is carried out by shifting the black body temperature feature so the graph will display a spectral power density that varies to the wavelenght. Numerical approach was used in this research is Newton Raphson methods by Python program. Both of simulation and numerical approach yield the value of the maximum wavelength (λ_max) for a black body temperature variation. The black body temperatures and their appropriate maximum wavelength data then analyzed using linear regression. Final result show that value Wien’s constant using PhET is 2,93 × 10-3 mK with relative error obtained is 1,07 % while using Newton Raphson the Wien’s constant value obtained is 3,07 × 10-3 mK with relative error is 5,90 %. The two approachs carried out produce data that slightly different, but still in a very good accucracy range when compared with theory. So, PhET Simulation and Newton Raphson methods effective to examine the value of the Wien’s constant.

Weather is a very important factor in supporting various human activities. However, weather is a natural event that keeps on changing due to various air conditions that affect it. One way to anticipate weather changes that may occur early is to create a system that can predict weather changes. Fuzzy logic is one of the methods that can be used in system prediction to find out the cause at a certain time and place. In this system, two fuzzy logic methods were used, they are the Mamdani and Sugeno methods, with three supporting criteria, including air temperature, humidity, and air pressure. In this research, data levers were carried out in June 2022 and resulted in a percentage accuracy of 73.34% for the Mamdani method and 70% for the Sugeno method.

This study aims to find out class VII students’ profiles of Pancasila abilities of MTs SA Miftahul Huda Bumijawa. The dimensions of the meticulous Pancasila student profiles include four dimensions, namely critical reasoning, creativity, mutual cooperation, and independence. This type of research is a qualitative descriptive. Data collection instrument were observation and interview guidelines. Based on research data, the results showed that the ability of students to the Pancasila student profiles were still very low. 70% of students were in category of very low and another 30% were in category of low on the critical reasoning dimension. 57% of the students were in category of very low and another 43% were in category of low on the independent dimension. Overall students where in category of very low on the dimensions creative and mutual cooperation dimensions. It indicates that the applied learning media and learning models have not been able to strengthen Pancasila student profiles. The Integrated Science learning process still uses conventional methods and rarely does practicum or projects. The media used is still limited to textual. One of the potential solutions in order to strengthen the Pancasila student profiles are to develop an e-module based PjBL.
本研究旨在了解七班学生对MTs SA mittahul Huda Bumijawa的Pancasila能力概况。细致的Pancasila学生档案的维度包括四个维度，即批判性推理，创造力，相互合作和独立性。这种类型的研究是定性描述性的。资料收集工具为观察和访谈指南。根据研究数据，结果表明，学生对Pancasila学生概况的能力仍然很低。70%的学生在批判性推理维度上处于非常低的类别，另外30%的学生处于低类别。57%的学生在独立维度上属于非常低的类别，另外43%的学生在独立维度上属于低类别。总体而言，学生在创造性和相互合作的维度上处于非常低的水平。这表明，应用学习媒体和学习模式未能加强Pancasila学生的形象。综合科学的学习过程仍然使用传统的方法，很少有实习或项目。使用的媒介仍然局限于文字。为了加强Pancasila学生档案，一个潜在的解决方案是开发一个基于PjBL的电子模块。

The study aim is to analyze soil quality for dryland agriculture with variations in fertilization and plant rotation in Argomulyo sub-district, Salatiga city. This study took samples on dryland agricultural land in Ledok Village by taking sample points using random sampling with a cluster sampling pattern by dividing them into 4 clusters. The Step of the research are field and laboratory observation to know the soil pH and moisture, also to determine the soil value and cation test, respectively. Next is the interview step to know the effect of fertilization and plant rotation variation. This research uses quantitative description analysis techniques. Based on the field observation was obtained the cluster 2 has pH value around 6.5 in the category slightly acidic. Then, for cluster 1,3, and has 4 neutral pH category in the range 6.6 – 7.5. The humidity of clusters in the dry category is in the range of 0 - 30%. Laboratory observation shows cluster 3 has a lower resistance around 8.1KW and has the best cation exchange capacity (CEC) test compared with other clusters. Based on the results of interviews, cluster 2 received organic fertilization and crop rotation occurred. Clusters 1 and 4 have not received any planting activity since October 2020. Meanwhile, fertilization in cluster 3 uses inorganic fertilizers. So Cluster 2 soil quality is better than the other three clusters due to organic fertilization and plans rotation so that the soil nutrients become stable. Cluster 1 has poor soil quality due to variations in inorganic fertilization, neglecting the soil, and being planted Manihot esculenta which impacted the reduction in the amount of nitrogen and phosphorus in the land.
