Abstract

Striped catfish is one of the most popular types of freshwater fish consumed by Indonesians. Striped catfish contains Monounsaturated Fatty Acids (MUFA) and Polyunsaturated Fatty Acids (PUFA). MUFA in striped catfish (Omega-3, Omega-6, and Omega-9 Fatty Acids) plays an important role in fat transport and metabolism, immune system regulation, and maintaining cell membrane function and integrity. MATERIALS AND METHODS: This study is a descriptive study to compare and determine the analysis result of proximate, protein, and fat between cultivated and wild striped catfish, and compare the analysis of this study with other studies. RESULT: In this study, there was a significant difference in the proximal and fat levels of cultivated and wild striped catfish with α=0.021 (α<0.05), and there was no significant difference in protein content with α=0.021 (α<0.05). The results of comparison with other studies showed that the proximate, protein, and fat of striped catfish in this study were higher than in other studies. CONCLUSION: Striped catfish has a high protein and fat content, high adaptability, and is easy to cultivate. This study showed that cultivated striped catfish has a better result analysis of proximate, fat, and protein content than wild catfish. Therefore, striped catfish have the potential to be an alternative for nutrition improvement, and the cultivation of striped catfish may reduce the damage to wetland ecosystems.

Abstract

ISO 9001:2015 is a Quality Management System that to assist the operational business processes of each organization to achieve the vision and mission that has been set by the organization. Management's responsibility is to provide resources, including material, machines, humans, methods and money. Basically, the strength that exists in a company lies in the human resources (HR) in the company. If HR is treated properly and in accordance with its dignity, the company will achieve results in accordance with the goals desired by the company. The benefits of implementing ISO 9001:2015 certification for companies cause a positive assessment of the company's reputation. The ISO 9001:2015 certification implementation system also emphasizes customer-focused business processes, understanding customer needs and increasing customer satisfaction. In ISO 9001, Internal Audits must be carried out on companies or organizations to determine whether the implementation of the quality management system is running, and the internal audit can be a reference and preparation for later if there is an external audit from the certification body. Through the Gap Analysis checklist, it will facilitate the analysis of ISO requirement elements in the form of a checklist. Gap Analysis is effective because the checklist created is structured and in accordance with the topic. The checklist will cover all existing requirements and is made hierarchically in its assessment, this will include general questions and provide an overview of the topic or category to be assessed. The results showed a difference in the gap of 8.1% with a score of 91.9%. This indicates that Citra Abadi Sejahtera corporation is ready to implement ISO 9001:2015 and conduct certification. However, Citra Abadi Sejahtera corporation needs to make improvements according to the checklist that refers to the requirements of ISO 9001:2015 to cover the gap, especially by implementing the PDCA (Plan-Do-Check-Act) cycle.

Abstract

Present research was carried out to elucidate the diversity diversity of cellulolytic microbes from several depth in peat soil planted with oil palm. Soil samples were taken from wetlands cultivated to 2 years, 6 years, and 10 years old oil palm, as well as secondary forest, in Landasan Ulin Utara village, South Kalimantan. Soil samples were transported to the laboratory and used for determination of population of cellulolytic microbes, microbial C, soil pH, and water content. Correlation test was employed to assess the relationship between population of cellulolytic decomposer with microbial C, soil pH, and water  content. The results showed that the largest cellulolytic bacterial population was found at a depth of 0-40 cm from 10 years old oil palms, followed by a depth of >40 cm from 10 years old oil palms. There was no difference between cellulolytic bacterial populations from 6 and 2 years old palms at all depths. The lowest population of cellulolytic bacteria was found at a depth of >40 cm from forest soil. There were positive correlations between population of cellulotic decomposer with all parameter measured, except soil water content that were logistic negatively correlated. The relationship between water content (Y, mm/day) and the population of cellulolytic decomposer (x, cfu/g soil) can be described with equation Y = log (-0.0051x + 162.65).  These findings suggested that the organic matters supplied by oil palm, especially the 10 years old oil palm) enhance the diversity of cellulolytic microbes. These results may also suggest that the cellulolytic microbes were mostly from aerobic type.

Abstract

Peat soil is a soil that is rich in organic matter, hence contains many essential nutrients, such as nitrogen, to support plant growth. During the vegetative period, plants need a lot of nitrogen as a source of nutrients for plant growth. Other than soil organic matter, nitrogen can also be obtained from     N2 gas in the atmosphere by the Nitrogen Fixing Bacteria. This study aimed to determine the number of non-symbiotic nitrogen-fixing microbial populations on peatlands and their relationship with the urease enzyme activity of peat soil cultivated to sengon (Albizia chinensis), petai (Parkia speciosa), pineapple and orange. Soil samples were taken from rhizoplane of sengon, petai, pine apple, and orange in Landasan Ulin, South Kalimantan. Six soil samples were taken from each plant in wet season and dry season of 2021 and 2022. The soil samples were transported to the laboratory and used for non-symbiotic nitrogen-fixing microbial and urease enzyme determination. The data obtained were then analyzed to follow the Nested Randomized Complete Design (CRD). The results showed that the number of nitrogen-fixing microbes during dry season was more than that of wet season. The highest number of nitrogen-fixing microbes during dry season was observed in orange rhyzoplane, while the highest nitrogen-fixing microbes during wet season was observed in pane apple rhyzoplane. The number of nitrogen-fixing microbes had a positive correlation with urease enzyme activity.

Abstract

The city of Banjarmasin has the potential for religious tourism, especially tourism objects in the form of the tombs of the Ulama (Habib) and old mosques that have Islamic historical value in Bumi Lambung Mangkurat, including the Sultan Suriansyah Mosque, Sultan Suriansyah's Tomb, Surgi Mufti's Tomb, Al Allamah Datu Muhammad Amin's Tomb (Habib Datu Amin or Habib Benua Anyar), Tomb of Al Habib Hamid bin Abbas Bahasyim (Habib Basirih), and Tomb of Habib Abu Bakar Bin Salim Al Habsyi (Habib Basirih). This study aims to 1) explore the potential and obstacles faced by religious tourism objects from the historical, physical, and socio-cultural aspects of the surrounding community, and 2) analyze the development of religious tourism objects in Banjarmasin City. This research is a qualitative descriptive study describing the object of research in the form of Islamic religious tourism in Banjarmasin City along with the potential and obstacles faced, which are expected to be further developed as an integrated pilgrimage tourism destination. The results of the study indicate that the constraints that exist in religious tourism objects are related to the lack of availability of facilities and infrastructure and their maintenance, the weak ability of local resources in developing and marketing various products that can be sold around religious tourism objects, and the weakness of promotional programs. The development that can be done is by running an appropriate marketing program for religious tourism objects; proper promotion and positioning of religious tourism objects as pilgrimage tourism, improving infrastructure, facilities, and infrastructure, and establishing cooperation between the government, managers, and the community in maintaining and maintaining the sustainability of religious tourism objects in Banjarmasin.

Abstract

The problem of rice cultivation at C type tidal lowland (it does not receive high tidal water inundation) is water shortage. The research objective was to develop an open water level control model to support rainwater storage in order to provide the water requirement for rice crops. The research method was a field experiment. Land with an area of 16 ha (one tertiary block) was planted with rice variety Inpari 32 at first planting season (MT 1) for the period October-February 2019/2020. Rainwater harvesting was done by maintaining the open water level in the canal at minimum depth of 50 cm (controlled drainage) resulting in saturated soil conditions and enable rainwater storage, which can be used to fulfil the rice water requirement. The water control gate operation was done by applying a controlled drainage system (opened gate). Annual rainfall of > 2500 mm at normal conditions is sufficient for rice cultivation, but if the annual rainfall is less than 2500 mm such as in 2019, then water supply is needed by using pump irrigation at the initial planting period and generative phase period. A water pump is operated if there is no rainfall during more than 10 days. Rice production is very good with average yield of 7.5 ton/ha such as at first planting in 2020.

Abstract

The importance of in-depth exploration and design of Ethno-STEM (Ethno-Science, Technology, Engineering, and Mathematics) as a valuable learning resource within the realm of phytochemistry. This research aims to examine the diversity of local Ethno-STEM culture, design it, and use it as a transformative tool to enhance students' metacognitive and higher-order thinking skills, with a specific focus on addressing pressing environmental issues. In this study, an exploratory qualitative method is used with ethnographic techniques, knowledge extraction from indigenous communities, and laboratory investigations into the phytochemical properties of local flora. In order to learn phytochemistry, we are exploring the potential of Banjar, South Kalimantan's traditional ethno-scientific heritage. The subjects of this research are community leaders and academics who understand Banjar culture and ethnoscience. Data collection was carried out through observation, writing, and interviews. The results of this research show the important role of metacognitive skills in the learning process because they facilitate orientation-representation, planning, monitoring, and evaluation skills. The integration of Ethno-STEM knowledge not only enriches students' understanding of phytochemistry but also encourages the development of higher-order thinking skills for environmental problems (HOTSEP), including critical thinking, problem solving, and developing creative innovations to overcome environmental problems in the field of phytochemistry. The conclusion of this research proves that there is a synergy between indigenous knowledge, Ethno-STEM design for phytochemical learning, the development of metacognitive skills, and higher order- thinking. The results of this research not only contribute to the preservation and appreciation of cultural heritage (Banjar ethnoscience), but also have extraordinary potential for cultivating a generation that is environmentally conscious and able to solve problems.

Abstract

Tidal swamp land is an alternative land that has great potential for agricultural development in the future. At present time, the rice productivity in tidal areas vary from relatively high to low. This diversity is caused by obstacles and problems, including low soil fertility, acidic soil reactions, the presence of pyrite, high levels of Al, Fe, Mn and organic acids, deficiency of P, poor base cations such as Ca, K, Mg, and suppressed microbial activity. This research aimed at determining the role of several soil properties (pH, soluble Fe, available P, organic C, soil CEC, presence of pyrite and groundwater level) on rice production in tidal areas. This research is field research using survey methods. Sampling in the field was carried out using purposive sampling technique, namely referring to differences in rice production of the Karang Dukuh variety in Barito Kuala Regency. Soil samples were taken at a depth of 0-20 cm from the ground surface three points at each location with different rice production level. The research results showed that only three variables had a partially significant effect on rice production, namely soil pH, soluble Fe and available P. Together these three variables play a major role in rice production in tidal areas which best (coefficient of determination of 0.919) approached with aquation Y ( rice production ) = 1,501 − 0.011 Fe-soluble + 0.269 P-available + 0.561 Soil pH. C-organic content, soil CEC, pyrite depth and water level play a very small role (≤ 8.1%) in rice production in tidal areas (coefficient of determination ≤ 0.081).
