Abstract

Fish stock assessment can be estimated by dependent and independent sampling; Mark-recapture studies is a part of independent sampling method that can be used for it. This study was conducted in 2018 using purposive sampling methods. The purpose of this study was to determine the current status of fish stocks and the composition of fish species in the floodplain/oxbow lake, Jambi city. Interviews were conducted to determine the types of fish in this area as a reference, and then, the composition of fish species, modification of fishing gear and combine with mark-recapture sampling. The total catch was 66.5 Kg, with the dominant compositions were Hemibagrus nemurus (42%), Pangasius sp (20%), Channa lucius (12%) and the others were 26% (Osteochilus haseselti, Osteochilus bornensis, Barbonymus schwanenfeldi, Labiobarbus festivus, Thynnichthys polylepis, Mystus sp, Cryptopterus spp, Bothia macrocanthus, Labeo chrysophekadion, Barbycthys loevis and Macrobrachium rosenbergii). The conversion result of fish catches with the total area, which has been assessed using Mark-recapture studies, was 558.6 kg/ha. Finally, the total area of the floodplain was estimated at 60137 ha, and the fish stock was 66.4151.7 tons. Its showed that, allowable catch should be under this value, and Mark-recapture studies is one simple methods can be used to predict fish stock in floodplain areas.Keywords:Fish stockfloodplain lakeMark recapturemanagement

Abstract

Karakteristik Deep-v planing hull sangat dipengaruhi oleh bentuk dan kecepatan kapal. Bentuk pada haluan kapal akan mempengaruhi performance kapal pada saat kondisi air tenang dan gelombang. Semakin tinggi kecepatan kapal maka akan semakin sulit untuk memprediksi karakteristik kapal tersebut. Pada penelitian ini akan menggunakan pendekatan Computational Fluid dynamic (CFD) dengan menggunakan metode moving grid mesh untuk mengevaluasi karakteristik kapal pada saat kondisi air tenang dan gelombang regular. Perhitungan numerik menggunakan persamaan RANS (Reynolds-Averaged Navier-Stokes) dengan model turbulensi k-ε untuk memprediksi aliran turbulen. Hasil simulasi pada kondisi air tenang hambatan menunjukkan trend yang baik pada kecepatan rendah, sementara pada kecepatan tinggi ada perbedaan yang signifikan. Pada kondisi gelombang regular hasil simulasi numerik masih perlu pendekatan yang lebih baik.

Abstract

The Association of Indonesian Life Insurance Companies (AAJI) has encouraged insurance companies to apply environmental, social, and governance (ESG) principles in their business activities. However, insurance companies in Indonesia generally have not fully implemented sustainability principles in their operational activities due to the uncertainty of increased fi rm values after the implementation. One way to communicate the company's sustainability steps is through the sustainability report (SR), which the Financial Services Authority (OJK) obliged. Although the guidelines had already been prepared in 2021, the depth and breadth of the disclosure depend on each company. Previous studies found that several factors aff ect SR disclosure. This study aims to investigate the role of profi tability and fi rm size as determinants of SR disclosure and the eff ect of SR disclosure on company value. The sample of this study was 15 insurance companies listed on the Indonesia Stock Exchange (IDX) that routinely published SR during the 2021-2023 period. The data was processed using Partial Least Squares - Structural Equation Modelling (PLS-SEM) through SmartPLS ver—3 software. The results of this study show that (1) profi tability has a positive eff ect on SR disclosure, (2) company size has a positive eff ect on SR disclosure, and (3) company size has a positive eff ect on company value.

Abstract

This study evaluates the effectiveness of different types of post-exercise drinks on rehydration in pencak silat athletes. Prolonged exercise in hot environments leads to physiological changes due to depleted glycogen stores and fluid-electrolyte loss through sweat. The aim of this study was to analyze the average difference between the effects of young coconut water (Cocos nucifera) and commercial isotonic drinks on the rehydration process. This experimental research involved dividing subjects into two treatment groups: Group 1 received young coconut water, while Group 2 received a commercially available isotonic drink. Dehydration status was assessed through measurements of body weight, urine pH, and urine specific gravity. Paired t-tests were used to analyze within-group differences before and after treatment, while unpaired t-tests compared differences between groups. The average fluid intake for rehydration was 1062.5 ml. Fluid administration had a significant effect on dehydration status (p < 0.05). A significant increase in urine pH was observed: 1.63 for coconut water and 0.97 for isotonic drinks. These results indicate a difference in the effectiveness of coconut water and isotonic drinks on hydration recovery.

Abstract

Arus globalisasi kini sedang meningkat di seluruh dunia, fenomena ini juga memiliki dampak yang signifikan terhadap kehidupan manusia saat ini. Arus globalisasi ini membawa beragam produk mulai dari teknologi yang semakin canggih, perubahan budaya dalam satu negara, bahkan hingga perkembangan ilmu pengetahuan dan pendekatan mengajar yang semakin inovatif dan modern. Jadi, globalisasi ini memiliki banyak sekali dampak positif dan negatif yang tentu saja harus kita perhatikan adalah dampak positifnya. Namun, masih ada saja manusia-manusia yang terjebak dalam arus globalisasi ini dan menuju ke jalan yang salah. Sebagian besar yang terdampar dalam aliran globalisasi ini merupakan anak-anak dan remaja di era ini. Peran pendidikan memegang peranan yang sangat penting untuk keberlanjutan dan menjaga diri manusia dari dampak makin kejamnya arus globalisasi. Salah satu hal penting yang bisa ditanamkan, terutama kepada anak-anak di Sekolah Dasar, adalah pendidikan mengenai nilai-nilai Pancasila. Di mana peran Pancasila ini berupaya untuk memberitahukan nilai-nilai terbaik yang harus dipatuhi dan melindungi diri dari dampak negatif globalisasi yang semakin tidak terbendung. Disebabkan peran Pancasila sebagai benteng melawan pengaruh arus globalisasi, pembangunan semangat kebangsaan di kalangan siswa sekolah dasar adalah sangat penting untuk memastikan anak-anak memahami pentingnya mencintai tanah air. Oleh karena itu, peran Pancasila serta pembangunan rasa nasionalisme pada era globalisasi ini sangatlah krusial bagi siswa sekolah dasar. Hal ini perlu ditanamkan sedini mungkin agar generasi berikutnya dapat menjaga pergaulan di tengah arus globalisasi.

Abstract

Universities are responsible for producing quality graduates and reducing dropout rates (DO), a serious challenge for the Widuri Institute of Social and Technology (ISTEK). This phenomenon has a negative impact on the quality of education and accreditation, making early identification of students who have the potential to drop out (DO) very crucial. This study aims to apply the Naïve Bayes algorithm to predict the potential for dropout (DO) of ISTEK Widuri students based on data on the activities of the 2021, 2022, and 2023 intakes. Naïve Bayes has proven effective in classifying students at risk of dropping out (DO). The Semester Credit Unit (SKS) attribute is the most dominant indicator, students with low SKS have a high potential for dropping out (DO). Model performance varies for each batch, in the 2021 batch it reached 90% accuracy (100% DO precision, 40% recall), the 2022 batch showed 93.75% accuracy (100% DO precision, 60% DO recall), and the 2023 batch had 86.67% accuracy (100% DO precision, 33.33% DO recall). This model is very good at validating students who are safe from DO (100% recall of Not DO in all batches). Even so, the model still needs to be improved so that it can find all students who are at risk of dropping out (DO) as a whole. The prediction results for students with the potential for DO at ISTEK Widuri Jakarta are expected to support more optimal prevention efforts and contribute to improving the quality of education.

Abstract

Cathodic protection is one of the methods used to protect metals from corrosion. This corrosion can occur due to the influence of the surrounding environment, such as salinity levels. ICCP PV is a cathodic protection method by flows direct electric current from the conversion of solar radiation. The purpose of this study is to determine the effect of water salinity on the capacity of PV components in the ICCP system. The type of material used in this research is SS 400 steel with salinity variations of 0‰, 30‰, and 35‰. The tests carried out are salinity test and load power test by considering metal potential. The experimental results show that 35‰ salinity ICCP requires the highest power of 13.09 watts. Calculation of PV component capacity at 35‰ salinity ICCP requires the largest capacity, which is 170 Wp PV module and 75 Ah battery for 14.68 m² plate area. Based on this, it is concluded that the higher the salinity of water, the greater the power required for the ICCP system, thus affecting the capacity of PV components for the ICCP system.
