Published: February 2023

: Discipline is an attitude that students need to have in learning in order to help students achieve learning goals. On the other hand, learning aims to train discipline so that students can behave correctly and have good character in society. This study aims to examine teachers' efforts to use positive reinforcement in increasing student discipline in the learning process. The research method used is descriptive qualitative. The data found by the author shows that the percentage of discipline in grade IV elementary school students is 63.2%. The teacher applies a positive reinforcement method that aims to improve student discipline. The use of positive reinforcement methods shows an increase in student discipline to 73.3%. The teacher has a role as a role model and guide in building student character. The conclusion obtained is that positive reinforcement shows the percentage of success of positive reinforcement on student discipline of 10.1%. The advice given is to make more specific disciplinary indicators and research is carried out over a longer period of time so that discipline improvements are more visible.

Anjhir Hill is a natural tourist attraction located in Tragah District, Bangkalan Regency which is still new and is still rarely known by many people. Based on observations, these problems are caused by a lack of promotion and publication to the wider community. Therefore, there is a need for promotional innovations to introduce this tourist destination. The purpose of developing this comic in three languages ​​is an effort to promote the natural tourist spot of Anjhir hill through language and science approaches. This research is development research using 4D development model which has 4 stages, they are Define, Design, Development, and Dissemination. The subjects of this study were high grade elementary school students in three elementary schools in Madura. Data collection techniques were carried out by observation, interviews, and questionnaires. Based on the percentage validation results from tourism promotion experts, linguists, and materials experts, it was obtained that they were 90%, 85%, and 80.5%, respectively. So that it is known that from the results of expert validation, comics developed obtain a valid category. In addition, based on the results of student questionnaire with an interpretation of score based on the Linkert scale as a whole, a percentage value of 85% is obtained in the very good category.

The purpose of this study was to analyze what problems occurred in the 2013 curriculum so that it was changed to the merdeka curriculum. This research is included in the qualitative descriptive research using the method narrative inquiry, namely the results of the research which is a detailed description of an event that we make the object of research, without exaggerating the information obtained regarding the analysis of the 2013 curriculum and the difficulties experienced so that it turns to the merdeka curriculum which is currently being discussed and being intensively implemented in schools elementary, starting from class I and class IV. From the results of the analysis, important findings were found, namely that there were 3 aspects of difficulties experienced by teachers in planning learning, carrying out learning and evaluating (learning assessment). So the Merdeka Curriculum was born which is a form of evaluation or refinement of the 2013 Curriculum, and is expected to be able to solve existing problems in the 2013 Curriculum. After going through a trial period of one year it can be said that the Merdeka Curriculum has provided a better picture than the previous Curriculum. Because, the Merdeka Curriculum found fewer problems and was able to solve problems in the 2013 Curriculum.

Published: February 2023

Academy in Pakistan is a gendered space that manifests and nurtures various forms of inequalities. This paper examines women’s experiences of working in Pakistani academies focusing primarily on factors influencing their career progression. Data for this paper is drawn from larger qualitative research on the experiences of women in the academy. Phenomenological interviews were carried out with fourteen participants including professors, associate professors, assistant professors, and lecturers from two Public universities in Pakistan. The paper unveils the struggles of women academics in sustaining in the academy due to prevailing gender norms. Several organizational challenges were narrated by the participants including; difficulties in conducting and publishing academic research, discrimination in appointments and promotion practices, workplace favoritism, lack of networking opportunities, and absence of mentors for junior faculty. Resultantly, women professors, irrespective of their ranks, qualifications, skills, and confidence, feel frustrated and find it difficult to contribute effectively to teaching and research. The paper contributes to the global debates on gender inequalities experienced by women in the academy. These findings call for a more gender-balanced approach in the academy to include women as equal stakeholders.

The engine is currently overheating because the cooling system's temperature increased by 80 oC after the overhaul. A "bench engine test," often referred to as a "assembly engine performance test," must be performed to measure the temperature rise before the engine is given to the customer. The test findings indicate that the PRC PT X standard engine is suitable for supplying SITE clients with high-quality components. In order to be corrected or prevented through engineering, the proposal identifies the root cause of the cooling system dyno test engine issue. The dyno test engine at PRC PT X is being tested in this investigation using the flow method. After the repairs, the cooling tower's output has cooled down and is now ready to be injected into the engine system at a temperature between 35 and 40 °C. This takes place as a result of the heat exchanger's ability to operate at peak efficiency. When executing a Komatsu engine performance test, all systems, starting with the fuel, oil, water, and electrical sensors, must be in working order and comply with manufacturer-required standard indicators. This will eventually lead to the testing process evolving into a quality method. Therefore, a quality process will result in a quality output.

The observation was held in one of small holder plantation located in Desa Sonomartani, Kecamatan Sukarame, Kabupaten Labuhan Batu Utara (north Sumatra). The palms were planted in shallow peat. The seedlings were assuming coming from illegitimate seeds. In general, like any other small holder palms, the farm was not well managed such as manuring was only applied ones per year with dosage 0.5 kg Urea.Â Weeding in palm circle and inter row is not totally cleaned.Â The observation was done during January to December 2013. The number of palms sampled is 238 palms or more or less one hectare. Â The stand trees in the area is 140 palms/ha. Average bunch weight during observation is average on 13 kg. Based on the observation, the trend of one year production was tent to distribute nearly in normal distribution.The yield potential is 21.8 ton FFB /ha/year. However, the actual yield was only around 9.9 ton FFB/ ha/ year. This actual production is still far lower from their potency.Â In order the yield achieve their potential, herewith some recommendation (i) The seeds planted much be certified seeds boughtÂ from legal seed producer, (ii), weeding must be done properly in which palm circle, harvesting path and inter-row must be free from any weed, (iii) manuring program must be correct dose, type, time and application.Â Drainage must be maintained to avoid water lagging.
