Cavitation in pumps is the most severe condition that centrifugal pumps can work in and is leading to a loss in their performance.  Herein, the effect of semi-open centrifugal pump side clearance on the inception of pump cavitation has been investigated.  The input pump pressure has been changed from 80 to 16 kPa and the pump side clearance has been changed from 1 mm to 3 mm at a rotation speed of 1500 rpm. It has been shown that as the total input pressure decreased; the static pressure inside the impeller is reduced while the total pressure in streamwise direction has been reduced, also the pump head is constant with the reduction of the total input pressure until the cavitation is reached. Head is reduced due to cavitation inception; the head is reduced in the case of a closed impeller with a percent of 1.5% while it is reduced with a percent of 0.5% for pump side clearance of 1mm, both are at a pressure of 20 kPa.   Results also showed that the cavitation inception in the pump had been affected and delayed with the increase of the pump side clearance; the cavitation has been noticed to occur at approximate pressures of 20 kPa for side clearance of 1mm, 18 kPa for side clearances of 2mm and 16 kPa for 3mm.

When there is combustion there are three main components that cause the fire which is commonly called the Fire Triangle. The fire triangle itself consists of unified and balanced Heat, Fuel and Oxygen that will cause fires to the point where workers are also very detrimental to the company if this happens if it is not immediately addressed. The author in collecting the data needed until the completion of writing this scientific paper, uses the method of approach and data collection by Observation and Literature Study on the MT ship. Katomas which is an oil product cargo ship which is a flammable liquid, the best extinguishing agent is foam fire extinguisher. Fire fighting equipment is also not only a supporting factor but also an indispensable factor and is part of the ship and its crew. Safety concerns the safety of the cargo, crew and ship itself. Then the damage to the fire extinguisher and the decline in the work function of the tool is due to lack of maintenance and attention to the extinguisher which causes the work of the device to be less than optimal. Keywords : Portable fire extinguisher, Foam fire extinguisher, Fire fighting equipment Saat terjadi pembakaran ada tiga komponen utama yang menyebabkan terjadinya api yang biasa disebut Segitiga Api. Segitiga api itu sendiri terdiri dari Heat, Fuel dan Oxygen yang bersatu dan seimbang yang akan menimbulkan kebakaran hingga membahayakan para pekerja juga sangat merugikan perusahaan apabila hal ini terjadi jika tidak segera ditanggulangi. Penulis dalam mengumpulkan data yang diperlukan hingga selesainya penulisan karya tulis ilmiah ini, menggunakan metode pendekatan dan pengumpulan data dengan Observasi dan Studi Pustaka pada kapal MT. Katomas yang merupakan kapal muatan Oil Product yang merupakan zat cair yang mudah terbakar, maka zat pemadam yang paling baik adalah jenis pemadam api foam. Peralatan pemadam kebakaran juga bukan hanya faktor pendukung tetapi juga merupakan salah satu faktor yang sangat diperlukan dan menjadi bagian dari kapal dan awaknya. Keselamatan yang menyangkut keselamatan pada muatan, awak kapal, dan kapalnya itu sendiri. Maka kerusakan alat pemadam api dan menurunnya fungsi kerja dari alat tersebut dikarenakan akibat kurangnya perawatan dan perhatian terhadap alat pemadam tersebut yang menyebabkan kerja dari alat tersebut menjadi kurang optimal.

Status: PostprintThis study aims to analyze the potential aplication of of palm oil-based foamingagent as peat fires fighter in Indonesia. From literature review, it has been known that thefoaming agent able to form foam to extinguish fire, wrap and refrigerate the burning peat. It isnecessary to develop the production and application of foaming agent in Indonesia becausepeat fires occur almost every year that caused smoke haze. Potential raw material for theproduction of environmental friendly foaming agent as foam extinguishing for peat fires inIndonesia aong other is palm oil due to abundant availability, sustainable, and foam producteasily degraded in the environment of the burnt areas. Production of foaming agent as firefightingin Indonesia is one alternative to reduce the time to control the fire and smog disasterimpact. Application of palm oil as a raw material for fire-fighting is contribute to increase thevalue added and the development of palm oil downstream industry.

The majority of people in Kuta Dame Village work as farmers. Several outreaches have been carried out to develop the agricultural sector in Kuta Dame village. However, some of the extension services rarely touched on effective technology to support agriculture in Kuta Dame village. One of the technologies that need to be developed by the Kuta Dame village farmer group in supporting agriculture is an automatic sprayer. This development is necessary because most farmers are still using the carrying type sprayer with a manual pump (diaphragm pump). The sprayer's diaphragm pump pressure produces a relatively low spray pressure, especially when the operator is tired of moving the pump lever. As a result, the spraying performance is not perfect, making the spray grains not smooth and not reaching the leaf surface evenly. A community service program was implemented to implement automatic sprayers for farmers in Kuta Dame village. This community service program aims to carry out the planning process and use of an electric sprayer appropriately to increase spraying fertilizers and pesticides on crops. Implementing this community service activity starts from planning activities, implementing academic counseling, implementing the practice, handing over an electric sprayer, monitoring, and satisfaction analysis.

The design features of the existing design and technology for the protection of downhole pumps of the ECV type from abrasive wear during operation are considered and analyzed. Based on the analysis, a new method for capturing solid impurities on the suction line of a borehole pump of the ECV type using a pressure-vacuum hydrocyclone is proposed. It is specified that at field tests of a prototype of new installation technological process is estimated on the pressure-expense characteristic and technological-operational indicators according to requirements of GOST 6134-81 " pumps dynamic. Test method. " In this case, the flow rate of the base pump on water is determined by means of a turbine water meter mounted on a water-lifting pipe with a valve. The performance of the hydraulic elevator is established by the volumetric method, and the head in front of the valve of the pump pressure pipe using an approximate pressure gauge. It is established that the flow-pressure characteristics of the base submersible pump ECV are provided in full (water flow 60-70 m3/h, head - 110-118 m), overload on the electric motor is not detected (ammeter readings are within the permissible limits-68-71 amperes), the degree of water purification is 95-96%. It is noted that the implementation of a flexible packer device with slots and the presence on the surface of the second minihydrocyclone-thickener significantly improves the functioning of the adopted scheme of water treatment. It turned out that with this technology, the overload of the pump motor is reduced by cooling with water without mechanical impurities.

Проанализировано применение погружных (плавающих) насосов в насосно-рукавных комплексах. Рассмотрены их преимущества перед центробежными насосами, устанавливаемыми в мобильной пожарной технике. На основе практики применения и технических характеристик погружных насосов, производимых ведущими зарубежными фирмами, сформулированы технические требования для разработки отечественного погружного насоса. Кроме того, технические требования могут стать основой разработки национального стандарта для этого типа пожарно-технической продукции. The article analyzes the results of operation of a relatively new type of centrifugal pump - a submersible (floating) centrifugal pump with a hydraulic drive. These pumps have a number of significant advantages over centrifugal pumps installed on mobile fire fighting equipment - they can be used to pump liquid from a mark up to minus 30 m. Since the suction pipe of such a pump is located directly in the pumped liquid (below the liquid mirror level), the phenomenon of cavitation is practically excluded. Submersible pumps are used to supply water in case of fire and for water disposal during the elimination of hazardous hydrological phenomena, both independently and in conjunction with centrifugal pumps installed on mobile fire fighting equipment (supply to pumping). All submersible pumps included in the set of hose-pumping complexes are of foreign production. The demand for such pumping units causes the need to develop domestic samples in order to get away from import dependence in the manufacture of pumping and hose systems and their operation. Based on the practice of using submersible pumps and the technical characteristics of submersible pumps produced by leading foreign companies, the following technical requirements for the development of a domestic submersible pump have been formulated. Pump delivery is 170-180 l ∙ s from the mark to minus 30 m. Water intake is possible both in equipped (adapted) and unequipped (unsuitable) places. In addition, the requirements for the hydraulic drive, weight and size characteristics, and some components have been formulated. In conclusion, some directions for the further development of pumping and hose systems and submersible pumping stations are considered.
