Abstract

This study aims to explain the effect of media-assisted problem-based learning using ChemCollective on buffer solution material on the critical thinking skills of 11th grade students at SMAN 1 Narmada. This quasi-experimental study used a nonequivalent control group design and was conducted in classes XI F5 and XI F6 with a total of 72 students. Cluster sampling was used as the sampling technique. The determination of the experimental class and control class was based on the lower average pretest score as the experimental class and the higher score as the control class. The pretest results obtained in class XI F5 were 53.44 and class XI F6 were 59.69, so class XI F5 was the experimental class and class XI F6 was the control class. The data collection technique used a two-tier multiple-choice test instrument. The results showed that the average N-Gain score was 0.6 in the experimental class and 0.34 in the control class, both of which were in the moderate category. The t-test result obtained was tcount (4.25) > ttable (1.994), so Ho was rejected and Ha was accepted. It can be concluded that the use of media-assisted problem-based learning chemcollective on buffer solution material had an effect on improving the critical thinking skills of grade XI students at SMAN 1 Narmada.

Abstract

This research was conducted due to the low problem-solving skills and learning outcomes of students at SMA Negeri 13 Bone due to unattractive conventional learning methods and the minimal use of interactive learning media. This study aimed to determine the effect of implementing the Problem-Based Learning model supported by SPICO (Spinner Game Economy) learning media on student learning outcomes at SMA Negeri 13 Bone. This study was a pre-experimental study with a One Group Pre-Test and Post-Test design. A sample of 35 students was selected using a random sampling technique. Data were collected through learning achievement tests and documentation, then analyzed using descriptive and inferential statistics, including normality tests, homogeneity tests, and paired sample tests. The results showed a significant increase, from an average pre-test score of 39.86 to a post-test score of 85.43, with the majority of students in the high to very high categories. These findings indicate that the implementation of PBL supported by SPICO media has an impact on student learning outcomes at SMA Negeri 13 Bone and encourages students to be more active, critical, and confident in their learning.

Abstract

Oyster Mushroom Cultivation at KM 15, Balikpapan City produces up to 4,000 kg of baglog waste within a 3-month period. The baglog waste, which serves as the growing medium for oyster mushrooms, is merely stacked and discarded into the surrounding forest without proper treatment. Accumulation of baglog waste can cause environmental pollution as it becomes a breeding ground for wild fungi. Composting offers a potential solution for managing baglog waste. The composting process requires the addition of an activator to accelerate decomposition, such as fermented rice-based Local Microorganisms (MOL), which contain Lactobacillus sp. and Saccharomyces sp. Rice-based MOL is rich in carbohydrates, which serve as nutrients for microorganisms. This study aims to analyze the quality of compost produced from oyster mushroom baglog waste using rice-based MOL as a bioactivator, as well as to determine the effect and optimal volume of MOL on compost quality. The composting process was carried out using the aerobic Takakura method at a laboratory scale over a 30-day period. The variations of rice-based MOL used were 0 mL, 100 mL, and 250 mL. The quality of the resulting compost was compared against the Indonesian National Standard (SNI) 19-7030-2004. The results of the study showed that the control treatment, as well as the addition of 100 mL and 250 mL of MOL, met the compost quality standards for temperature, pH, odor, color, texture, moisture content, nitrogen, phosphorus, organic carbon, and C/N ratio. However, the potassium parameter did not meet the standard. Based on the graph, the addition of rice-based MOL indicates a positive effect on compost quality improvement. The optimum MOL volume for all parameters was 250 mL, although the potassium parameter still did not meet the SNI 19-7030-2004.

Abstract

The research conducted by this researcher is something that can be used to understand the importance of applying the characteristics of Islamic marketing and the importance of customer satisfaction for a bank. This study aims to determine how the impact of sharia marketing characteristics on customer satisfaction in deposit products made by Bank Mitra Syariah Gresik. This field research used a qualitative approach, using primary data and secondary data. Then retrieve data sourced from interviews with banks and customers and supporting data, namely through journals and the internet as a reference for relevant researchers. The data testing method used by researchers is data triangulation. The type of triangulation used in this research is source triangulation, namely by checking the data obtained through 3 (three) sources. The results of this study indicate that the characteristics of sharia marketing that have been carried out by Bank Mitra Syariah employees have had a good impact on customers. In marketing deposit products, Bank Mitra Syariah employees have implemented the characteristics of sharia marketing. The characteristics of sharia marketing are theistic (rabbaniyah), ethical (akhlaqiyyah), realistic (al-insaniyyah), and humanistic (al-waqi'iyah). Customers are satisfied with the characteristics of sharia marketing implemented by employees of Bank Mitra Syariah Gresik.

Abstract

The need for clean water is one of the essential aspects of community life, especially in areas that are not fully served by the PDAM (Regional Drinking Water Company) distribution network. In Sumber Rejo Subdistrict, particularly in RT 7, the availability of clean water remains a major issue due to the hilly topography, making it difficult for the PDAM pipeline network to reach the area. The local community relies on springs as an alternative water source, which is collected manually without a planned distribution system. This study aims to analyze the potential of the spring in RT 7, Sumber Rejo Subdistrict, as a clean water source based on water quality, flow rate classification, and clean water distribution system planning. The methods used include water quality analysis through laboratory tests covering physical, chemical, and microbiological parameters, flow rate classification based on spring discharge measurements, and distribution system planning using EPANET 2.2 software. The results show that the spring water quality does not fully meet the clean water quality standards according to the Indonesian Ministry of Health Regulation Number 2 of 2023 on Environmental Health, particularly for nitrate, manganese, and aluminum parameters. Based on the flow rate measurements, the spring falls into Class VI, with a flow rate ranging from 0.1 to 1 liter per second, indicating low flow capacity and generally only sufficient to meet water needs on a limited scale (less than 1,000 people). In the clean water distribution network simulation, three alternative distribution scenarios were evaluated, with Alternative 2 showing the most optimal results, with flow velocities ranging from 0.31 to 0.46 m/s
