Conventional gasoline engines suffer from low performance and NOx emissions. Controlled auto-ignition (CAI), sometimes referred to as homogeneous charge compression ignition (HCCI), is a promising concept to solve such problems. CAI has the potential to improve spark ignition (SI) engine fuel economy while at the same time solving the trade-off of NOx-soot emissions found in compression ignition (CI) engines. The CAI engine can reach a fuel economy comparable to that of a conventional diesel engine with ultra-low NOx and negligible soot emissions. However, controlling auto-ignition remains the biggest difficulty that hinders the implementation of CAI as a commercial engine. Research towards a cleaner and more efficient engine is driven by the progressively stringent emission regulation imposed worldwide. Therefore, the CAI was developed to meet the emissions target while maintaining engine performance. CAI works on the principle of lean mixture and auto-ignition. To obtain CAI combustion, the temperatures in the cylinder must be sufficient to initiate auto-ignition. Without the use of a spark plug or injector, the CAI suffers from a direct control mechanism to start the combustion. The most practical approach to controlling the initiation of auto-ignition in CAI is diluting the intake charge by either trapping the residual gas or recirculating the exhaust gas. Both approaches enable the engine to achieve CAI combustion without requiring significant modifications to control the onset of CAI combustion phase.
Fakultas Ilmu Komputer Universitas Bung Karno (FIKOM UBK) merupakan salah satu dari lima fakultas yang ada di Universitas Bung Karno. Jumlah mahasiswa aktif FIKOM UBK per tahun 2018 adalah 914 orang, dari 914 mahasiswa tersebut terdapat hanya 53 mahasiswa yang mulai merintis kewirausahaan. Kecilnya jumlah mahasiswa dan alumni FIKOM UBK yang merintis dan terlibat kewirausahaan disebabkan oleh beberapa hal, salah satunya adalah sistem pembelajaran yang diterapkan masih terfokus mempersiapkan mahasiswa untuk lulus tepat waktu dan mendapatkan pekerjaan, bukan lulusan yang siap menciptakan pekerjaan (job seekers). Solusi Tim pengabdi Program Pengembangan Potensi Kewirausahaan (PPK) untuk terhadap masalah ini adalah adalah menawarkan model pengajaran dan pelatihan kewirausahaan kepada mahasiswa FIKOM UBK melalui Pengembangan Potensi Kewirausahaan FIKOM UBK (PPK FIKOM UBK). Metode pendekatan PPK FIKOM UBK yang digunakan adalah Metode Pendekatan Participatory Action Learning System (PALS). metode PALS menitik beratkan peranan peserta secara aktif dalam proses pembelajaran sehingga terbentuk sistem pembelajaran yang partisipatif, metode ini terdiri dari tiga fase, yakni (1) fase penyadaran kewirausahaan (awareness), (2) fase pengkapasitasan dan pendampingan kewirausahaan (entrepreneurship capacity building), dan (3) fase pelembagaan (institutionalization). Hasil dari kegiatan PPK FIKOM UBK adalah berhasil mengembangkan potensi kewirausahaan mahasiswa dengan bukti berdirinya enam wirausaha baru yang kreatif dan inovatif serta tingginya minat dan motivasi mahasiswa untuk berwirausaha
The administrative system is very important in the world of trade and transactions, because with a good administrative system, business owners can know and control the flow of goods circulation and people around public services. Therefore, it is necessary to develop village potential trough out Microsoft Office Excel training so the community will be developed and increased the productivity of the potential in the village. Microsoft Excel is a program issued by Microsoft Office with a function as a numerical data processing program. Various kinds of data processing activities, making graphs, calculating data and others can be used in Microsoft Excel. Thus, training related to Microsoft Excel is carried out and it is hoped that this knowledge can improve abilities and support the potential that exists in Bojonggede village.
The readiness and accessibility of top-notch human resources must be harmonized with the current technology improvements and advancements. The country of Indonesia country, which has a population of around 275 million, has a lot of potential for developing its human resource base. However, preparing its human resources to compete in the global market is a challenge. Therefore, through partnership programs between educational institutions and various organizations, it is the best means of information transfer to increase knowledge and skills in the community. In order to carry out the Tri Dharma of Higher Education, the lecturers of the Computer System Study Program plan to conduct training activities in Pancoran Mas Village, Depok City. The lecturers of the Computer System Study Program at Bung Karno University plan to conduct training activities as part of the implementation of the Tri Dharma of Higher Education, this activity is carried out in Pancoran Mas Village, Depok City. This training activity was carried out in 2 time periods, namely on 21 and 28 July 2022 with the title graphic design training using Adobe Photosop software for PKK and Karang Taruna women, this training was attended by 11 participants consisting of 6 elements from PKK women and 5 participants from Karang Taruna elements. cadets. This activity is carried out using direct training and mentoring methods packaged into 3 learning models such as lectures, practice and sharing sessions, the results of this activity are able to provide new experiences, increase understanding, knowledge, and skills for participants in making a design object. The level of understanding of the original participants was 48.18% and at the end of the training participants were able to increase their understanding by 29.09% so that the understanding of participants now reaches 77.27%. This activity was successfully implemented and obtained satisfactory results based on the level of participant satisfaction of 72.4%.
An important factor in the maintenance of biota for flora and fauna in the aquarium is about lighting the lights to illuminate the aquarium space properly besides being able to invite the attention of connoisseurs of the beauty of skilled craftsmen of aquascape biota. Lighting settings in the aquarium can also be useful for the survival of aquatic animals such as ornamental fish and aquatic plants that adorn the beauty of the aquarium. Good lighting is lighting that allows the biota objects in the aquarium to be seen clearly. Fish keepers or people who come to see the biota in the aquarium sometimes don't, so the lights are on continuously which can lead to a waste of electrical energy. The reason for this research is to design and build a lighting control device for a microcontroller-based aquarium, which can work automatically using the ESP32CAM module with a camera feature to recognize that it is true that there is no object other than a human face with a detected facial object, then the lighting of the aquarium light becomes bright and will die if no facial objects are found around the aquascape aquarium.
