Abstract

Kenari (Canarium indicum L) belongs to the Burseraceae family and is one of the endemic fruits in Indonesia, especially Maluku. Walnuts have a tough shell that encloses the flesh, to get the flesh without damaging it careful effort is needed. This study investigated the strength of walnut shells through mechanical testing to determine the amount of impact force needed to break the walnut shell. The mechanical test carried out is a compression test and impact test. The values of these tests assist in determining, measuring, and analyzing the minimum and maximum force loads required to crack a walnut shell. Tests were carried out on walnut shells from 6 different villages on Ambon Island and Saparua Island. The impact test where the highest impact absorption energy value was found in walnut shells from Booi Village, namely 23.18 J/mm2, and the lowest in walnut shells from Morela Village, 22.40 J/mm2. In the compression test where the lowest value was found in walnut shells from Morela village with a value of 3.61 MPa while the highest value was found in walnut shells from Booi village, namely 5.24 MPa. Whereas the minimum compressive force is 16.22 kgf/mm2 and the maximum compressive force is 17.61 kgf/mm2.

Abstract

Optimizing Hydraulic Pump Units (HPUs) is a crucial step in increasing oil production rates at the AGL well in field X. HPUs are used to lift crude oil from production wells to the surface using hydraulic pressure. This research focuses on analyzing and improving various operational aspects of HPUs to address challenges such as hydraulic leaks, component wear, and control system failures. The methods employed include preventive maintenance, the application of advanced technology for real-time monitoring, and the adjustment of operational parameters to find the optimal configuration. The study results show that with proper optimization, production rates can be significantly increased, downtime can be reduced, and equipment lifespan can be extended. Continuous monitoring and performance evaluation of HPUs after implementing optimization also provide valuable insights for further improvements. This research is expected to offer practical guidance for the oil and gas industry in implementing HPU optimization to achieve more efficient and productive operations. Keyword : pump, oil and gas, production flow rate, hydraulic pressure, AGL filed well X

Abstract

Refrigeration has become an essential part in the design of spaces that will be occupied by people or products intended to provide space temperature, humidity, other process requirements. Refrigeration was originally used to produce ice, as technology advances, refrigeration has an important role in commercial and non-commercial refrigeration. Research on efficient refrigeration has been carried out by several previous studies. Previous methods were used by calculating cooling efficiency and heat loads that affect cold storage cooling.Based on an interview with one fishery company focused on processing quality seafood products located in PPN Tantui, PT Mina Usaha Harapan, the energy consumption for the cooling system takes up almost 70%-80% of the total energy expenditure of the company. Due to several factors, including excessive heat loads provision, or inefficient cold storage design. Therefore, author wants to calculate the cold storage performance in one of the seafood processing companies based on eco-fishing located in PPN Tantui, PT Mina Usaha Harapan.Calculations and analysis have been carried out in the previous chapter, several conclusions is made: 1) The average value of evaporator capacity is 34.96 kW for Cold Room and 57.39 kW for Air Blast Freezer 2) The calculated total load value (without product load) is 11.94 kW for Cold Room and 3.56 kW for ABF. 3) The company set a time of 9 hours to freeze 3500 kg of seafood, but according to calculation results, it only takes 7 hours to freeze 3830.4 kg of products with product temperature reaching -21 ͦC.Keywords: vapor compression cold storage, refrigeration load, cold room, abf, cold storage, evaporator capacity, seafood products

Abstract

Oil and gas are important resources that every country must fulfill and Indonesia, despite being a producer, has not been able to meet domestic demand. In field operations, wells do not always produce optimally, so an evaluation and optimization of pump performance is needed to produce optimal production rates. Research on the evaluation of the Sucker Rod Pump at Well M has been carried out by Untoro, E & Saleky, H (2023), obtained the results of the flow rate (Qmax) of 945.403 Bfpd, the current Q of 236.63 Bfpd, pump displacement (v) of 792.091091 Bfpd, and pump volumetric efficiency of 29.87497%. Thus, from the evaluation results, this research will optimize the Sucker Rod Pump, with the aim of obtaining Sucker Rod Pump optimization results to obtain the optimal production rate. Optimization was carried out by changing the pump SPM from 6 SPM to 8 SPM and the pump stroke length from 150 in to 145 in, so that the production rate increased from the previous 236.63 Bfpd to 355,3 Bfpd, and the pump volumetric efficiency increased to 34,77%.
