Abstract

Peanut (Arachis hypogaea L.) is an agricultural commodity that acts as a protein and vegetable oil source, but in Southeast Sulawesi, its productivity is still relatively low. This study aims to determine the effect of giving bokashi tofu waste and phosphate fertilizer on the growth of peanut plants. The research was conducted at the Experimental Field Laboratory II, Faculty of Agriculture, Halu Oleo University, Kendari, from June to September 2021. The study used a factorial randomized block design consisting of bokashi tofu waste with four treatment levels, namely 0, 5, 10, and 15 tons per hectare, and phosphate fertilizers with three treatment levels, namely 0, 100, and 200 kg per hectare. The total combination of treatments was 12, with three replications. Observational data were analyzed using analysis of variance and UJBD. The analysis results showed that the interaction of bokashi with tofu waste and phosphate fertilizer had a significant effect on plant heights 28 and 35 DAP, stem diameter 21 DAP, leaf area 14, 21, and 28 DAP, and root loss ratio. Bokashi tofu waste independently significantly affected plant height, stem diameter 28 DAP, leaf area, and root loss ratio. Phosphate fertilizer independently significantly affected plant height at 28 and 35 DAP, leaf area at 14 and 21 DAP, and root loss ratio. The combination of 15 tons of tofu waste bokashi per hectare and 100 kg of phosphate fertilizer per hectare was the best treatment for increasing the growth of peanut plants.

Abstract

The purpose of this article is to explain the terms and procedures of jarh wa ta'dil. a researcher must have in-depth knowledge of the terms and procedures of jarh wa ta'dil, because the science of jarh and ta'dil includes a discussion of a critic's assessment of the good and bad or defects of the hadith narrator. It is important to know the terms and procedures in jarh and ta'dil because they relate to a hadith and its rawi which is one of the conditions for accepting a hadith.

Abstract

The road is an infrastructure that plays an important role in people's daily lives. Therefore, it isnecessary to maintain and repair road conditions regularly. The existence of budget constraints causesnot all damaged road sections can be handled. So that in handling road repairs it is necessary todetermine priorities. In determining the priority of road improvement there are criteria that are takeninto consideration in decision making. One method of analysis that can be used to overcome complexitydue to various criteria is the Analytical Hierarchy Process (AHP) method. The AHP method is used toobtain the weight of 4 criteria that are taken into consideration in determining the priority of roadimprovement, namely road conditions, traffic volume, costs, and road classification. Calculation of scoresfor each road improvement proposal is obtained by multiplying the priority weight of the criteria by thecriteria value of each proposal. The results show that the Decision Support System that is designed canproduce a ranking of alternatives in the form of road improvement proposals based on predeterminedcriteria, so that it can be used as a basis for decision making to determine road improvement priorities.

Abstract

This study aims to determine the implementation and evaluation of online learning at SDN Perumnas 9 Tangerang. This type of research is a qualitative descriptive research. The research method used in collecting information is by using observation. The results showed that online learning at SDN Perumnas 9 Tangerang mostly used the WA group application as a medium in providing learning materials and the Quizizz application as a learning evaluation medium. There are several shortcomings in this online learning, such as not all students have Android phones, the background and characteristics of children are different, so it is necessary to evaluate learning as a benchmark for the success of learning. Based on the results of research conducted, online learning is not the best learning method because it is still less effective and difficult to do. Teachers cannot directly assess the development of students. The teacher also cannot see whether the students have understood or not the material that has been delivered.

Abstract

This study aims to analyze the effectiveness of using a realistic mathematical approach to improve critical thinking skills in fourth grade elementary school students at SDN Perumnas 9 Tangerang. The method used is experimentation by giving an initial test in the form of story questions that provoke students to think about solving these questions. After the results were obtained on the initial test, a realistic mathematics approach was carried out with two lessons. After that, a final test was carried out to test the effectiveness of a realistic mathematical approach in learning. Based on the results of the analysis, it can be described as an increase in the critical thinking skills of elementary school students after being taught using a realistic approach. Students can connect formulas, numbers in mathematics to solve everyday problems. In addition, students are more enthusiastic and motivated to solve the problem.

Abstract

An energy-efficient stove powered by used oil is an innovative solution designed to reduce dependence on conventional fossil fuels and utilize unused oil waste. This research concentrates on the creation of an efficient stove system that utilizes used oil as its primary energy source. This stove's specific design ensures optimal combustion, minimizes harmful emissions, and enhances heat efficiency. We employ an integrated heating method to maximize energy output, utilizing heat-resistant material construction and a controlled airflow system. We conducted testing of the stove under various operational conditions to measure its performance, temperature stability, and fuel consumption. The results of the experiment show that this stove not only produces stable heat but also has a higher efficiency level compared to traditional stoves. The implementation of this technology is expected to provide an economical and environmentally friendly energy alternative as well as serve as a sustainable solution in the management of used oil waste.

Abstract

This research aims to investigate the effect of mesh size on the coconut shell charcoal grinder machine on the grinding time and the quality of the produced briquettes. We tested different mesh screen sizes to determine the optimal grinding time and their impact on the briquettes' characteristics, including density, compressive strength, and combustion efficiency. The research results show that the sieve size has a significant impact on the grinding time and the quality of the briquettes. A 0.5 mm sieve results in the longest grinding time, while a 1 mm sieve provides the fastest grinding time. The smaller the sieve size, the longer it takes to achieve the desired fineness. Other factors such as compressive strength and combustion still influence the quality of the produced briquettes, even though the 1 mm sieve increases time efficiency. Therefore, we recommend using the 1 mm sieve for time efficiency, but further testing is necessary to ensure optimal briquette quality, particularly in terms of density and combustion efficiency.

Abstract

Globalisasi telah membawa masuk berbagai budaya luar, yang secara alami memicu perubahan budaya dalam masyarakat. Dalam menghadapi dinamika ini, nilai-nilai tradisional seperti gotong royong yang mulai tergerus oleh perkembangan teknologi perlu diperkuat kembali, khususnya di kalangan siswa, agar tetap lestari. Penanaman nilai gotong royong sangat penting, terutama bagi siswa sekolah dasar. Pendidikan Pancasila menjadi salah satu mata pelajaran yang dapat membantu menanamkan nilai tersebut, sekaligus mendorong rasa kebersamaan dan kerja sama di kalangan peserta didik. Penelitian ini bertujuan untuk mengeksplorasi pentingnya menanamkan nilai gotong royong melalui Pendidikan Pancasila di sekolah dasar. Pengumpulan data dilakukan dengan menyebarkan kuesioner kepada 66 guru sekolah dasar, dan data dianalisis menggunakan metode kuantitatif. Hasil penelitian menunjukkan bahwa menumbuhkan semangat gotong royong adalah salah satu tujuan penting guru dalam mengajarkan Pendidikan Pancasila. Gotong royong mendorong siswa untuk saling membantu dan peduli, serta melalui kerja sama, mereka dapat menyelesaikan tugas dengan lebih efektif, meningkatkan partisipasi, dan menghasilkan pencapaian yang lebih optimal.
