Gas buang pada kendaraan berbahan bakar fosil yang tidak ramah lingkungan akan berdampak buruk terhadap lingkungannya. Pengembangan gas biomassa juga bisa dipakai untuk bahan bakar alternatif pada motor pembakaran dalam. Syngas hasil gasifikasi yang kandungan CO2, CO, NOx lebih rendah membantu mengurangi emisi gas buang. Pada reaktor gasifikasi untuk menghasilkan gas yang mudah terbakar didapatkan air fuel ratio 1,01; 1,13; 1,34; 1,52. Artinya campuran antara serbuk kayu dan udara dapat menghasilkan gas sebagai campuran bahan bakar pada mesin diesel. Penelitian ini bertujuan untuk mengetahui perbedaan kandungan gas buang pada single dan dual fuel. Dengan putaran pada mesin konstan yaitu 1500 rpm dengan pembebanan pada generator set mulai 200 watt sampai 2400 watt dengan interval 200 watt. Setelah dilakukan eksperimen, temperatur gas buang dengan adanya penambahan syngas akan semakin semakin naik hingga 249áµ’C. Untuk emisi gasi buang dengan penambahan syngas, karbon monoksida (CO) turun sampai 0,71%. Nitrogen okside (NOx) juga mengalami penurunan seiring panambahan syngas sebesar 100 ppm. Serta hidro karbon (HC) seiring penambahan syngas pada emisi gas buang turun hingga 64 ppm

Pengetahuan dan keterampilan dasar dalam mengoperasikan komputer saat ini sudahlah menjadi kebutuhan yang tidak dapat dihindari lagi. Berbagai kegiatan atau aktivitas hidup manusia di jaman moderen ini tidak dapat lepas dengan bantuan komputer untuk membuatnya menjadi lebih mudah, cepat dan efektif. Sebagai contohnya aktivitas pekerjaan manusia yang berkaitan dengan komputer diantaranya: pekerjaan dengan pengolah kata (word processing), pekerjaan dengan tabel (table processing), membaca berita, browsing artikel di internet, bermain game, mengirim dan menerima email. Begitu banyaknya tugas pekerjaan manusia yang dapat dikerjakan dengan bantuan komputer membuat banyak program maupun aplikasi yang dirancang untuk berbagai tujuan. Program teknik (engineering software) merupakan program khusus yang dirancang dengan tujuan untuk membantu manusia untuk menyelesaikan berbagai perhitungan dibidang teknik. Pada pengabdian masyarakat ini kami ingin memberikan pengetahuan dan meningkatkan keterampilan kepada siswa SMA/SMK di Banjarmasin tentang perancangan aplikasi atau program yang berkaitan dengan teknik khususnya dibidang teknik mesin, dengan cara memberikan pelatihan perancangan aplikasi interaktif dibidang teknik mesin ini. Adapun metode pelatihan yang digunakan pada pelatihan ini nantinya adalah kombinasi dari teori dan praktek, dimulai dari pengenalan dasar pemrograman, pengenalan identifier, pengenalan variabel dan pengenalan IDE (Integrated Development Environment) sehingga diharapkan akan memudahkan peserta untuk menguasai materi yang diberikan. Peserta juga akan diberikan berbagai contoh studi kasus perhitungan dalam dunia teknik yang kemudian dicoba untuk dibuat aplikasi programnya. Target luaran dari kegiatan pengabdian masyarakat ini adalah jasa pelatihan pemrograman teknik dan publikasi yang akan diterbitkan adalah jurnal pengabdian nasional.

Computers have been widely used in the community, because computers can ease human work. To operate it, you need special knowledge about computers to be able to run it properly. Although computers make human work easier, computers can also be damaged or error. Only some people can repair computers like computer technicians. Therefore, on this occasion we had the opportunity to provide training on how to assemble computers and repair them. With expertise in assembling and repairing computers, the community can also open up jobs that would certainly have a positive impact on the surrounding community. Computer users / Personal Computers (PC) have been found in various circles, one of them is SMKN2 students. But many computer uses (PC) do not know how to repair a computer in case of damage, not to mention a few technicians or computer experts who can be easily found. Because of this, damage to the computer will be a difficult problem to deal with. Although there are very few technicians that we can find, repairing or servicing computers requires quite expensive costs. On this occasion, we intend to hold community service in the form of PC technician training (Personal Computer) for SMA/SMK students who aim to provide understanding and skills in making repairs, assembling, and upgrading PCs with community service programs in the form of this training. Besides this training is not limited to the provision of theory, but combined with practice so that not only knowledge is given, but the skills and creativity that are honed in this training. Outcomes of this training are skills training services and publications in national service journals.
