Dynamic Modeling Analysis of Paddle Aerator Performance on Litopenaeus vanamei Ponds

Ariadi, Heri, Linayati, Linayati, Mujtahidah, Tholibah
Abstract: Paddle aerator is an important tool in intensive shrimp farming. The purpose of this study is to determine the performance and electrical power consumption of paddle aerators based on the results of dynamic modelling analysis.… lysis. This study uses causal ex-pose facto design concept with data analysis using dynamic modelling system. The results showed the salinity levels of pond 1 20-27 gr/L and pond 2 31-33 gr/L, pH pond 1 7.9-9.0 and pond 2 8.1-8.3, DO concentration pond 1 4.43-6.93 mg/L and pond 2 4.72-5.99 mg/L, temperature pond 1 27.15-31.400C with a brightness of 43 cm and pond 2 ranging from 27.50-29.850C with a brightness of 49 cm. From the calculation of the level of oxygen production paddle aerator power 1 HP produces oxygen average 2.12 mgO2 / hour (1.68-2.89 mgO2 / hour) with gas pressure 10.31-16.00 mmHg and paddle aerator power 2 HP produces oxygen average 3.20 mgO2 / hour (2.82-3.65 mgO2 / hour) with gas pressure 10.05-14.56 mmHg. From the accumulated results, the electrical load power required for pond 1 is about 6.83-10.38 kW and pond 2 is about 6.59-7.71 kW. The performance of 1 HP paddle aerator is more effective than 2 HP paddle aerator 4 pieces. The results of dynamic model analysis estimated the level of dissolved oxygen production by paddle aerators during one cultivation cycle ranged from 1-2.70 mgO2/hours and 1-2.75 mgO2/hours with a rotational speed of 0-30 rpm/s and power requirements of 8-10 kW. The conclusion from the results of this study is that the use of 1 HP paddle aerators in large quantities is proven to be more effective and based on the results of dynamic modelling system analysis, it is shown that the performance of DO production by paddle aerators will stagnate at week ten of the cultivation period, with increasing electrical power requirements.

HUMAN RESOURCE DEVELOPMENT BASED ON KAYUH BAIMBAI VALUES TO OPTIMIZE EDUCATION QUALITY AT SMPIT BANJARBARU CITY

Annisa Zahra, Husnul Madihah, Agustina Rahmi
Abstract: This study aims to: 1) Analyze in depth how the implementation of human resource development based on the value of paddle baimbai in SMPIT Robbani and SMPIT ANIC Banjarbaru. 2) Evaluate the programs that have been implemented… ented in human resource development in the two schools. 3) Analyze the obstacles and challenges faced. This study uses a qualitative approach with a case study type in the form of information in the form of descriptions. Documentation data collection techniques, observations, interviews with 2 principals, 5 deputy principals, and 4 teachers. Data processing techniques: reduction, data presentation and conclusion drawing. The results of the study show that: 1) The implementation of human resource development based on the value of paddle baimbai at SMPIT Robbani is carried out based on teamwork and collaboration. Meanwhile, in SMPIT ANIC is based on morals and self-potential. 2) Programs implemented at SMPIT Robbani include APNI, IHT, Kombel, Morning Instruction, Training, Workshop, Supervision, Coaching, tahsin and teacher tahfizh. At SMPIT ANIC, there are training, mentorship, leadership development, character development and English learning. 3) The obstacles faced by SMPIT Robbani are the time of activities at the same time as other activities, lack of understanding, limited human resources, difficulties in implementation, and lack of motivation. The challenge faced is maintaining commitment. Meanwhile, the obstacles to SMPIT ANIC are limited time and availability of resources, underestimating training, resistance and motivation. The challenge faced is to change the mindset and ensure consistency of implementation in schools.
