The Analysis of the Water Quality of Peristis Lake and Limboto Lake as Irrigation Water Sources in Gorontalo Province Marike Mahmud1*, Fitryane Lihawa2, Aryati Alitu3, Rawiyah Husnan4, Barry Labdul5 Fakultas Teknik Universitas Negeri Gorontalo Abstract This study aims to analyze the water quality of Perintis Lake and Limboto Lake as water sources of irrigation in Gorontalo Province. The review was carried out based on the research objective, namely the use of water as irrigation water for flowing rice fields. The sampling locations were carried out in 2 lake locations, namely Limboto Lake and Perintis Lake. The research became an initial survey so that the location of each lake was one location and one time sampling. The parameters studied included temperature, TDS, COD turbidity, phosphate, pH, nitrate, iron, manganese, cyanide, arsenic, Florida, chlorine, manganese, magnesium, calcium, sodium, potassium, total coli and E.Coli. The analysis was carried out at the Gorontalo District Health Office of UPTD Water Quality Laboratory Installation and LPPT Gadjah Mada University. The sampling method for Total Coli and Coliform was carried out aseptically, and measurements in the laboratory used the MPN method. The way of taking chemical and physical samples followed SNI 8995-2021. Data analysis employed Government regulation number 22 of 2021 attachment VI regarding lake water quality standards and the like. Analysis of water for irrigation purposes applied the Sodium Adsorption Ratio (SAR) classification. The results showed that the water quality of Perintis Lake and Limboto Lake did not meet the requirements of Government Regulation no 22 of 2021 because the Chlorine, COD and Phosphate parameters were above the required quality. Limboto Lake^s pollution level was higher than Perintis Lake. The results of the SAR analysis for Perintis Lake obtained 7.542 including water criteria with Low Sodium, and Limboto Lake was 11.23 with Medium Sodium criteria.

Willem Iskandar, Psr V, Medan, North Sumatra, INDONESIA 20221, E-mail: msitumorang[at]unimed.ac.id Abstract Abstract Preservation of tropical forest plants that have high economic potential, such as Sumatran Benzoin (Styrax benzoin Dryander), by providing quality seeds is urgently needed. The purpose of this study was to propagate the Sumatran Frankincense (Styrax benzoin) plant to produce good quality seeds needed to meet the needs of seedlings for forest conservation. Styrax benzoin micropropagation technique was carried out using explants from very good quality parent plants. Micropropagation was carried out using explants from the best plants to produce seeds with the same frankincense production quality as the parent plant. Various types of explants have been used for such as seed embryos, young leaves, and shoots. Micropropagation was carried out in a completely randomized design with two factors: concentration of NAA (0-3 mg/L) and BAP (0-3 mg/L). The combination of NAA and BAP in culture media at optimal conditions proved to be effective in inducing callus and plant growth. The success of micropropagation has the potential to produce seeds of the same excellent quality as the parent plant in large quantities in a relatively short time. This technique is expected to be able to meet the conservation needs of community forests and national forests, and in the long term will increase the production of frankincense as a non-timber forest commodity as raw material for medicine.

Contextual Sociology Teaching Materials for Sociology learning in high school. Erianjoni Erianjoni1*, Deski Beri2, Alfajri Yusra1 1Sociology Department, Faculty of Social Science,Universitas Negeri Padang, Jl.Hamka, Air Tawar, Padang, Indonesia, 25132- 2Chemistry Department, Faculty of Mathematics and Science, Universitas Negeri Padang, Jl.Hamka, Air Tawar, Padang, Indonesia, 25132- Abstract The condition of teaching materials on concepts, principles, and attitudes in Sociology textbooks in high school are irrelevant to the context of student life where sociology is taught, thus causing alienation for educators and students. So the sociology learning taught at the high school level is not indigenous to the socio-cultural conditions of the local community and is more Western (Europeancentric) with universal values. This research aims to identify teaching materials on the components of concepts, principles, and attitudes to produce a reconstruction model in contextual sociology teaching materials. The approach used in this research is a qualitative approach with a case study type. Determination of informants was carried out by purposive sampling technique with informants consisting of a board of experts, lecturers, and teachers of sociology. Data collection using in-depth interview techniques, FGD (Focus Group Discussion), and documentation studies. The data were validated by triangulation of sources and methods, while the data analysis was carried out using the semantic analysis model from Yan Zhank and the interactive analysis from Miles and Huberman. The results of the research on the reconstruction of contextual sociology teaching materials can be carried out through three reconstruction models, namely: (a) reconstruction of universal material concepts with local concepts, (b) reconstruction of universal material principles with local concepts, and (c) reconstruction of national attitudes (nationality) with a local attitude. This reconstruction resulted in the sociology of text teaching materials being contextual sociology teaching materials. The reconstruction carried out on Sociology textbooks in high school can contribute ideas about the reconstruction model of contextual sociology teaching materials in sociology subjects at the high school level.

Abstract Civil servants need several competencies such as knowledge, skills and attitudes to carry out their main tasks, functions of authority and mandated responsibilities. To help building the civil servants^ professionalism, one of the important things that can be done is through the implementation of competency development training. Based on observations, civil servant competency development trainings within the Gorontalo City Government were still being done manually, for example processing training data, competency development, checking the number of training hours, submitting training reports, and storing data related to the activities. This raises several obstacles that negatively impact the process of organizing competency development training, such as data entry error and less accurate reports produced. This study aims to create a computerized application of competence electronic information system using the PHP programming language and MySQL database so that the information of competency development training implementation can be carried faster and more accurately. Rapid Application Development (RAD) method is used in building this application. RAD is a combination of several structured methods or techniques using prototyping methods and other structured techniques to determine user requirements and design information systems. The study results are the application design of competence information electronic system and its implementation for employees of Gorontalo City Government Environment which is online and integrated with all application in the Gorontalo City Education and Training Personal Agency which can help the regional apparatus organizations to submit planning data for civil servant competency development to the Gorontalo City Education and Training Personnel Agency.

Political Literacy of Generation Z Voters Towards 2024^s Election Eka Vidya Putra, Reno Fernandes and Abdi Azzara Universitas Negeri Padang Jalan Prof. Hamka Air TawarPadang Sumatera Barat Abstract This article aims to determine the level of political literacy of Generation Z voters towards 2024 General Election and also analyze the role of school institutions to improve political literacy. The background of this article is that more than 60 percent of voters in the 2024 General Election are Generation Z. One indicator of a quality election is the literacy level of the voters. Knowing the literacy level of voters early is very useful for quality preparation for the 2024 General Election. The result can be a recommendation for many parties, one of which is the school. As education providers, schools can play a role in building critical awareness. Especially for students, who incidentally will become voters in the 2024 General Election. The method used in data collection is the mix method. The level of political literacy is carried out quantitatively while the role of schools is carried out qualitatively. Related to the first question, the four findings are: first, Generation Z^s political knowledge is more on political issues than substantial matters- second, the response to the political issues of Generation Z is more cynical and apathetic- third, interest in political issues depends on conversations that go viral on social media- Fourth, TikTok and Instagram, the two applications that are most often used as sources of information. While the second question resulted in three important findings, namely. first, online learning brings students and teachers closer to digital, this situation can be an opportunity to produce creative content with political literacy content- and second, curricular programs with specialization pathways can be developed and directed to increase students^ analytical skills in political literacy.

Potential Development of Pattern Recognition System for Balinese Cultural Objects in Informatics Education Made Windu Antara Kesiman Virtual, Vision, Image, and Pattern Research Group Faculty of Engineering and Vocational Universitas Pendidikan Ganesha Abstract The development of pattern recognition technology which is part of the field of computer vision is very rapid in the last three decades. This is supported by the development of machine learning technology with the concept of deep learning. With so many research communities interested in further exploring these pattern recognition methods, newer corpus and pattern recognition datasets are needed and have their own challenges. Existing corpus and datasets often no longer offer new challenges or only have the characteristics of the usual pattern recognition features that are often found in the problems they propose. The problem of pattern recognition in the field of computer vision finally shifted to problems with new challenges in the form of special art and cultural objects. Apart from visual characteristics, these cultural objects do have certain characteristics, the need for a pattern recognition system for these cultural objects is real. Especially when these cultural objects become one of the assets of the tourism industry. This paper provides a comprehensive explanation of the potential of several Balinese cultural objects that have been used in image recognition research. In addition to contributing to the formation of new corpus and datasets in the domain of computer vision and machine learning, the research for Balinese cultural objects also provides added value in terms of cultural and tourism industry.

The Relationship of Organization Maturity Level and Enterprise Resource Planning (ERP) Adoption (Case Study: ERP Implementation in Indonesian Companies) Gede Rasben Dantes Universitas Pendidikan Ganesha Abstract The research was a preliminary study aimed at finding the relationship between the organization maturity level, implementation approach and Enterprise Resource Planning (ERP) implementation success. Seven companies which have implemented ERP system to support their operational were chosen as the object of the study, covering four different industrial sectors, namely: telecommunication, manufacturing, automotive and oil & gas companies. To address the study objectives, a survey of 37 respondents from these 7 companies was conducted. Survey results showed that based on Information System (IS) Roles, 29.05% of the companies were in the strategic level, 22.30% were in the managerial level and 48.65% were in the operational level. This demonstrates that organization maturity level did not automatically drive the organization to implement ERP. Other factors like technology trend, government policy, bank policy, political issue were more dominant factors to drive organization to adopt ERP rather than maturity level. The result of the study also shows that there is no pattern of relationship between organization maturity level and ERP implementation success. This implies that the implementation of ERP in those companies have been done trivially. ERP adoption was not administered by a mature plan in the sense that it was not designed in accordance with the IS/IT plan owned by the companies. It is also found that ERP implementation success more caused by implementation strategy rather than the organization maturity level.

It is necessary to investigate more deeply the rules and essential values, so that the understanding of the meaning of this dance is completely intact for the Gorontalonese as well as the Bolaang Mongondownese. The research integrates the ethnographic techniques with methodical experiments in learning non-traditional choreography for the department of Pendidikan Seni Drama, Tari dan Musik at Universitas Negeri Gorontalo. Ethnographic techniques place field research simultaneously with literature studies, to create a qualitative-phenomenological analysis process that considers emic and ethical data. The choreography process adapts Hawkins exploration model as a guide for realizing experimental works, which also creates an intersubjective understanding discourse process on the Kabela. The results show that the presence of the Kabela is reinforcer of the tradition of ^eating the betel nuts^ as a noble tradition of the Bolaang Mongondow people in welcoming guests, newcomers, or ^others^ who visit their area, while the concept of non-traditional choreography makes sense of the meaning in the production of imaginative and sensory effects, so that the process of appreciation of the dance is active and dynamic.

FUNCTIONAL ANALYSIS OF GRAMMATICAL SUBJECT IN RESEARCH ARTICLE INTRODUCTIONS WRITTEN BY NOVICE WRITERS Refnaldi Universitas Negeri Padang Abstract This study investigates the types and discourse functions of grammatical subjects in research article introductions written by Indonesian novice writers in five language teaching journals. This study was carried out on a corpus of 50 research article introductions (10 from each journal) published from 2018 to 2022. The corpus was analysed based on Gosden^s (1993) classifications that include 16 types of grammatical subject. The results indicated that 10 types of grammatical subject were used in the corpus and the frequencies of these types varied across the five journals. Besides, the results reported high similarities concerning the discourse functions served using the grammatical subject types.

Analysis of Performance Diesel Engine by Using a Mixture of Diesel Fuel and Coconut Oil Jemmy Charles Kewas, Augustinus R. Butarbutar, Hendro M Sumual, Zuldesmi, I. P. Tamba. Mechanical Engineering Departement, Faculty of Technique, State University of Manado, Indonesia Abstract Ignition energy is an important key factor needed in modern life concept with regard to a high technology usage. Almost 90% of the world^s energy needed is obtained from fossil fuels, where diesel fuel is one of them. Coconut oil is one of bio-diesel resources which is very potential to be developed and it has a potency to replace diesel fuel. It is, therefore research regarding the effect of diesel fuel and coconut oil mixture on engine torque and rate of fuel consumption at various RPM variations is needed to be done. The tested engine was done on a 1200 cc Isuzu Panther using a mixing ratio of diesel fuel (S) and coconut oil (MK), namely: (1). 100% S: 0% MK (pure diesel), (2). 95% S: 5% MK, (3). 90% S: 10% MK, and (4). 85% S: 15% MK. The research method was a quantitative testing method on a laboratory scale. Research finding shows that the engine torque at the 95: 5 and 100: 0 mixtures has almost the same value of almost all of engine rotations. At the 90: 10 and 85: 15 mixing ratio, the engine torque tends to be unstable significant. It can be concluded that the ideal and stable engine torques were found at the combustion of 100: 0 and 95: 5 fuel mixtures. The lowest fuel consumption rate occurred at the combustion of 100: 0 and 95: 5- while the highest fuel consumption were occurring on a mixture of 90:10 and 85:15.

The Effect of Valve Gap on Lambda, AFR, and Fuel Consumption Rate of Octane Fuel Series Jemmy Charles Kewas, Zuldesmi, Hendro M. Sumual, I. P. Tamba, Y. Rampo, H. Dj. Liow Mechanical Engineering Departement, Faculty of Technique, State University of Manado, Indonesia Abstract On a four-stroke motorcycle engine there is a valve mechanism that functions as a regulator of the entry and exit of the air and fuel mixture, and combustion gases. In the valve mechanism there are rocker arm components and valve stems. Over time, the gap between the rocker arm and the valve stem can change due to wear and tear so that it can affect the performance of the motorcycle engine. Therefore, it is necessary to adjust the valve clearance periodically. Often the mechanics adjust the valve gap only based on feeling without measuring the gap with a feeler gauge, for this reason, research is carried out to determine the effect of valve gap variations on fuel consumption and exhaust emissions on 125 cc motorcycle engine. The research method used is experimental, by testing the effect of valve gap variations of 0.03 mm, 0.05 mm, 0.08 mm and 0.10 mm on fuel consumption and exhaust emissions, which was carried out at a stationary rotation of 2000 RPM for two minutes using octane fuel variant. The results showed that the highest Lambda value is 1.487 occurred at a valve gap of 0.05 mm with Pertamax fuel, and the lowest is 1.304 occurred at a valve gap of 0.08 mm with Pertamax fuel. The highest Air Fuel Ratio (AFR) value is 20.84 gr air/gr fuel on Pertamax fuel with a valve gap of 0.03 mm, while the lowest is 19.14 gr air/gr fuel on Pertamax fuel with a valve gap of 0.08 mm. The most significant fuel consumption is 6.88 mL in Pertamax fuel with a valve gap of 0.08 mm, while the smallest is 5.84 mL in Pertamax fuel with a valve gap of 0.05 mm. So the conclusion of this study is the value of Lambda, AFR, and the Rate of Fuel Consumption have the same trend, there is the most significant value for each fuel occurs at the valve gap of 0.05 mm, while the smallest value occurs at the valve gap of 0.03 mm and 0.08 mm.
