Fishermen in the coastal area of Kebunrejo hamlet, Alasrejo village, Wongsorejo sub district, Banyuwangi district are traditional fishermen. The boat used is a small boat with a sail. Catching fish is carried out by fishing line which is stretched out with strings. Storage of catches using simple foam boxes. The use of sail has weather problems that cause the total fishing trip travel time to be ± 5 hours. The amount of travel time and a simple storage box causes the freshness of the fish to be not optimal and the selling value is relatively low. Community partnership program activities are carried out with the aim of increasing the income level of fishermen with the application of diesel engines with propellers. The partners are 4 (four) fishermen. Activities carried out by designing, manufacturing and using a 24 Hp diesel engine with 2 blades brass propeller as a replacement for the sail driving power. The results of the activity show that the partners get technical benefits including improvements to boat propulsion device, increased speed of movement of boats at sea, relatively low fuel needs and operating costs, and income opportunities from actors in sea fishing tourism.

In order to reduce pollutants of the emission from diesel vehicles, complex after-treatment technologies have been proposed, which make the fault detection of diesel engines become increasingly difficult. Thus, this paper proposes a canonical correlation analysis detection method based on fault-relevant variables selected by an elitist genetic algorithm to realize high-dimensional data-driven faults detection of diesel engines. The method proposed establishes a fault detection model by the actual operation data to overcome the limitations of the traditional methods, merely based on benchmark. Moreover, the canonical correlation analysis is used to extract the strong correlation between variables, which constructs the residual vector to realize the fault detection of the diesel engine air and after-treatment system. In particular, the elitist genetic algorithm is used to optimize the fault-relevant variables to reduce detection redundancy, eliminate additional noise interference, and improve the detection rate of the specific fault. The experiments are carried out by implementing the practical state data of a diesel engine, which show the feasibility and efficiency of the proposed approach.

And Performance

Market globalization necessitates the development of heavy duty diesel engines that can operate at altitudes up to 5000 m without significant performance deterioration. But the current scenario is that existing studies on high altitude effects are still not sufficient or detailed enough to take effective measures. This study applied a single cylinder direct injection diesel engine with simulated boosting pressure to investigate the performance degradation at high altitude, with the aim of adding more knowledge to the literature. Such a research engine was conducted at constant speed and injection strategy but different ambient conditions from sea level to 5000 m in altitude. The results indicated the effects of altitude on engine combustion and performance can be summarized as two aspects. First comes the extended ignition delay at high altitude, which would raise the rate of pressure rise to a point that can exceed the maximum allowable limit and therefore shorten the engine lifespan. The other disadvantage of high-altitude operation is the reduced excess air ratio and gas density inside cylinder. Worsened spray formation and mixture preparation, together with insufficient and late oxidation, would result in reduced engine efficiency, increased emissions, and power loss. The combustion and performance deteriorations were noticeable when the engine was operated above 4000 m in altitude. All these findings support the need for further fundamental investigations of in-cylinder activities of diesel engines working at plateau regions.

Operational Characteristics

The article considers and solves the problems of adapting the mathematical models, used in calculating operational characteristics of diesel engines burning mineral diesel oil, to engines converted to RME biofuels. The analysis of mathematical models of calculating the main technical and economic characteristics of diesel engines as well as the parameters of the in-cylinder process and the concentration of toxic substances in the exhaust gases is performed. The need for adjusting the calculation algorithms is also demonstrated. The computer programs based on single-zone thermodynamic models are used in the research. The programs of mathematical modelling are modified, i.e. supplemented with the algorithm for calculating energy characteristics of the combustion products (e.g. specific heat capacity, internal heat, the lower calorific value, etc.). Based on the computer programs, modified for examining diesel engines burning biofuels, the computer-aided mathematical modelling experiment is carried out. The results of modelling are compared with the data obtained in testing the diesel engine 1A41. The mathematical modelling performed demonstrates the accuracy acceptable for solving practical problems: the difference between the obtained calculation results and diesel engine testing data for the load range of (1.0÷0.5) Pi nom does not exceed ± 5÷7%. Higher accuracy of modelling the characteristics of diesel engines, operating in the low- and medium-load modes, may be accounted for by the adjustment of the algorithm for calculating the induction period and the on-set phase of fuel injection.

Atlikta skaičiavimo algoritmų analizė ir pagrįsti pagrindiniai jų tobulinimo aspektai. Sukurtas kompiuterinis programinis modelis, skirtas darbinio kūno dyzelio cilindre energiniams parametrams skaičiuoti (specifinei šilumai, vidinei energijai), dyzeliui dirbant plačiąja elementinės cheminės sudėties biodegalų gama. Atliktas 1A41 dyzelio techninių ir ekonominių bei ekologinių rodiklių modeliavimas kompiuteriu, naudojant patobulintus matematinius modelius. Parodytas gautų rezultatų, pakankamų praktiniams uždaviniams spręsti, tikslumas: dyzeliui dirbant artimos nominaliosios apkrovos režimais (1,0÷0,5) Pi nom skirtumas tarp skaičiavimo ir dyzelio motorinių tyrimų rezultatų neviršija ±5÷7%. Dyzeliui dirbant mažos apkrovos režimu, matematinio modeliavimo rezultatų adekvatumo didinimas susijęs su kuro įpurškimo fazės bei savaiminio užsiliepsnojimo indukcijos periodo skaičiavimo algoritmo tobulinimu. Резюме Рассмотрены и решены задачи адаптации математических моделей расчета показателей дизеля при переводе их работы с минерального дизелина на биодизелины метилового эфира рапсового масла (МЭРМ). Выполнен анализ и дано обоснование направлений доработки расчетных алгоритмов ряда однозонных термодинамических математических моделей, используемых в практике исследования эксплуатационных показателей, параметров индикаторного процесса и эмиссии токсичных компонентов в выхлопных газах дизелей. В форме программного модуля составлен алгоритм расчета энергетических параметров рабочего тела в цилиндре (удельной теплоемкости, теплоты сгорания, внутренней энергии) для топлив с широким элементарным химическим составом. С использованием доработанных компьютерных программ выполнен широкий расчетный эксперимент и сопоставлены его результаты с данными моторных стендовых испытаний одноцилиндрового отсека дизеля 1А41. Показана приемлемая для решения практических задач точность математического моделирования: для нагрузочных режимов (1÷0,5) Pmi расхождения расчетных и экспериментальных значений параметров работы дизеля не превышают ±5÷7%. Повышение качества моделирования показателей дизеля на режимах средних и малых нагрузок связано с уточнением алгоритма расчета периода индукции и фазы начала видимого горения топлива в цилиндре.

This Community Service is a Community Partnership Program that was carried out by to partners of the Brown Sugar Cane Business Group in Latellang Village, Patimpeng District. The processing of sugar cane so far has been very simple, and some of the sugar cane businesses were out of business due to the consumption and need for brown sugar cane by the community, especially the Latellang and other villages, who are reluctant to consume brown sugar cane. This reluctance is caused by the aroma of brown sugar cane. Therefore, diversification of brown sugar cane products was carried out by processing brown sugar cane into Liquid sugar and Recengan sugar. The results of the PKM program were able to provide partners with increased knowledge of processing brown sugar cane into a diversified product that has high economic value and reduced the price of brown sugar cane from Rp. 10,000 per kilogram into products with 250 grams of brown sugar cane as raw material. 2-3 bottles of Liquid Sugar (250 ml plastic packaging) with a price of Rp.10,000 per bottle and produce 15 pieces of Recengan Sugar. Especially for Recengan sugar packaging, it is packaged in pouch containing 8 Recengan sugar ata a price of Rp.10,000. The impact will be revive the production of cane brown sugar to the Cane Brown Sugar Business Group partners, especially in Latellang Village.

Environmental education is needed to increase community resillience, with knowledge and skills in order to understand environmental problems, be motivated to act, and solve or prevent certain environmental problems. Building social resilience in utilizing while preserving the environment is one of the important factors for sustainable environmental management. One of the efforts is by increasing people's understanding and love of biodiversity in order to increase their motivation to manage it sustainably. To provide an engaging and dynamic learning environment for Generation Z or gen Z, a creative approach is adopted that combines technology with social interaction and feedback that stimulates curiosity and motivation, and simulates real-life situations. The problem agreed upon by the team of this program and partners was the students' low recognition of biodiversity and its function for the environment. In the long term, this could have implications for a lack of appreciation for biodiversity, including a low appreciation for the presence of plants and animals endemic to North Sulawesi. The solution applied is to introduce various types of plants and animals, with an emphasis on endemic species, and their benefits for humans and the environment. After the community partnership program (PKM, Program Kemitraan Maysarakat), the student groups of SDN 36 and SDN 70 Kota Manado (main target) as well as teachers and students involved (additional targets) increase their knowledge about biodiversity and its function for the environment and can apply planting and maintaining various local fruit-producing trees in schools and the surrounding environment. The community partnership program activities are carried out in Kelurahan Kleak, Malalayang District, Manado City, North Sulawesi Province for six (6) months. The service is carried out in several activities as follows. 1) Inventory of the school environment situation and student behavior in relation to their interactions with biodiversity. 2) Programming with partners. 3) Preparation of teaching modules. 4) Implementation of outreach activities in the form of webinars with active involvement of learners through presentations accompanied by interactive discussions. 5) Planting and distributing various types of plant seeds. 6) Preparing reports and writing articles for scientific publications.

The necessity of adapting diesel engines to work on vegetable oils is justified. The possibility of using rapeseed oil and its mixtures with petroleum diesel fuel as motor fuels is considered. Experimental studies of fuel injection of small high-speed diesel engine type MD-6 (1 Ch 8,0/7,5)when using diesel oil and rapeseed oil and computational studies of auto-tractor diesel engine type D-245.12 (1 ChN 11/12,5), working on blends of petroleum diesel fuel and rapeseed oil. When switching autotractor diesel engine from diesel fuel to rapeseed oil in the full-fuel mode, the mass cycle fuel supply increased by 12 %, and in the small-size high-speed diesel engine – by about 27 %. From the point of view of the flow of the working process of these diesel engines, changes in other parameters of the fuel injection process are less significant.
