Abstract

This article presents an investigation of the actual cooling effect on a lab-scale prototype of LPG-fueled vehicles. The cooling effect is obtained from heat absorption by LPG on the vaporizer. Water with a mass flow rate of 1, 2 and 3 lpm is flowed from the cooling box to the LPG evaporator and flow back to the cooling box. The car used in this study has a capacity of 1500 cc that rotates 1000, 1500, and 2000 rpm. The results showed that there was a relationship between cooling power with the increase in engine speed and mass flow rate of water that crosses the evaporator. The biggest cooling power is 378 Watts at 1000 rpm with a water mass flow rate of 3 lpm.

Abstract

This paper compares the three largest marketplaces in Indonesia as a marketing platform for temanggung coffee products. The three marketplaces are tokopedia, bukalapak, and shopee. PPPUD Team of Universitas Muhammadiyah Magelang accompanied two partners, namely Palatiga Coffee SMEs and Garuda Coffee SMEs in product marketing through the marketplace. Tokopedia is one of the marketplaces that have a high user rating and has the complete features of the two other marketplaces. Also, Tokopedia also supports Indonesian coffee by providing a special page of Hot List Kopi Indonesia. PPPUD team of Universitas Muhammadiyah Magelang is currently developing marketing through Tokopedia and does not rule out the possibility to expand the market by opening a shop in Bukalapak and Shopee

Abstract

In the past decade, the general method for measuring the performance of research and scientific publications in a Study Program at a Higher Education is by the Rough Value (Nilai Kasar, NK) calculated per three years. This value is derived from the accreditation instrument. In fact, the calculation of the performance of research and scientific publications with NK cannot represent an annual performance. Therefore, this paper presents a new method for calculating research and scientific publications performance with an index (IP-PS and IPub-PS), which is calculated annually. An example of quality measurement practice in the Automotive Diploma Program of Universitas Muhammadiyah Magelang. As a result, calculations with IP-PS and IPub-PS are more likely to present real conditions per year than using NK.

Abstract

This article presents an analysis of the development of fuel system technology in Liquified Petroleum Gas (LPG) vehicles compared to the development of a fuel system in a gasoline engine. We found that over the past 100 years of using LPG as an alternative fuel, there have been changes in LPG kits for six generations. The first and second-generation LPG kits are similar to the concept of a carburetor, LPG and air mix in front of the throttle valve through a mixer. The third-generation of LPG kits is equivalent to K-Jetronik on a gasoline engine. The fourth and fifth-generation follow the development of a multi-point multi-point injection system and the sixth generation follows the workings of gasoline direct injection (GDI). The sixth-generation of LPG kits, where LPG is injected into the combustion chamber, has an advantage in volumetric efficiency but due to high combustion chamber temperatures, it is necessary to develop injectors that are resistant to high temperatures.

Abstract

During deceleration, continuous fuel flows into the engine not only causing over fuel consumption but also increasing exhausts emissions. Therefore, this paper presents a simulation of AFR and fuel cut-off modeling in the LPG-fueled vehicle using Fuzzy Logic Controller (FLC). The third generation of LPG kits (Liquid Phase Injection, LPI) was chosen due to its technological equivalency to EFI gasoline engine and promising to be developed. Given that the fuel system control is complex and non-linear, FLC has been selected because of simple, easy to understand, and tolerant to improper data. Simulation results show that the AFR and fuel cut-off controller able to maintenance AFR at the stoichiometric range during normal operation and able to cut the fuel flow at deceleration time for saving fuel and reducing emissions.

Abstract

Gagasan ini ditujukan untuk perbaikan transaksi dan manajemen lapak rosok Quantum Leap di Kecamatan Candiroto Kabupaten Temanggung. Persoalan yang dihadapi mitra selama ini adalah: proses transaksi konvensional memerlukan waktu yang relatif lama; sering terjadi kekeliruan dalam perhitungan berat rosok dan harga; transaksi tidak terekam dengan baik; pencatatan cash flow dengan buku sering terjadi kesalahan hitung; pihak manajemen tidak mengetahui jumlah barang di gudang; dan pihak manajemen mengalami kesulitan dalam perhitungan keuangan. Dari hasil telaah permasalahan yang dihadapi, maka solusi yang dapat diusulkan untuk menyelesaiakan permasalahan adalah dengan komputerisasi transaksi. Tujuan khusus gagasan ini adalah untuk meningkatkan akuntabilitas transaksi dan keuangan. Jika gagasan ini diimplementasikan, akan ada potensi luaran berupa: 1) peningkatan mutu layanan jasa transaksi rosok yang mencakup sistem neraca digital yang terhubung dengan komputer untuk meningkatkan akurasi dan perhitungan harga dengan komputer untuk mempercepat proses transaksi; 2) peningkatan akuntabilitas keuangan pada lapak rosok yang memudahkan dalam penghitungan jumlah transaksi (jenis dan jumlah barang, nilai transaksi, periode); aliran kas (cash flow); keuntungan; zakat; bagi hasil bagi pemasok; dan biaya perawatan lapak.

Abstract

Mulai tahun 2011 produk kopi ditetapkan sebagai salah satu produk unggulan di Kabupaten Temanggung. Sejak saat itu, UKM kopi bermunculan di Temanggung dan sebagian besar merupakan produsen rumahan yang dikelola secara tradisional. Oleh karena itu, melalui pengabdian masyarakat Program Pengembangan Produk Unggulan Daerah (PPPUD) ini, dipilh 2 mitra yang telah memproduksi kopi bubuk masing-masing sudah 2 tahun dan membutuhkan difusi ipteks di bidang teknologi pengolahan, perbaikan manajemen produksi, pengembangan produk, pengurusan hak cipta, dan pemasaran. Pada mitra 1 (UKM Kopi Manungal), dilaporkan ada peningkatan produksi mencapai 150 kg dari sebelumnya hanya rata-rata 100 kg per bulan. Saat ini juga melayani jasa roasting untuk masyarakat sekitar UKM. Label juga sudah bisa cetak sendiri dengan paket komputer dan printer dari PPPUD dengan pelatihan desain dan pencetakannya. Pada sisi pengelolaan keuangan, saat ini sudah tertib administrasi standar UKM melalui pendampingan. Sementara itu, untuk mitra 2 (UKM Kopi Gesing), telah memproduksi dengan mesin roaster sendiri. Selain itu, UKM ini juga telah melayani jasa roaster kepada UMKM lain dan masyarakat sekitar. Hasil ujicoba, alat roaster mampu mengolah 36 kg kopi dengan 3 kg LPG.

Abstract

Salah satu tugas utama peneliti adalah mengkomunikasikan hasil penelitian kepada komunitas ilmiah yang lebih luas. Oleh karena itu, penyusunan artikel ilmiah sebagai salah satu media komunikasi harus dilakukan dengan hati-hati karena ide yang baik atau proses penelitian yang baik tidak tidak cukup untuk bisa diterima di jurnal bereputasi jika tidak ditulis dengan benar dan akuntabel. Perlu diperhatikan bahwa artikel yang baik mempunyai tiga komponen utama yang esensial, yaitu: (1) mengandung kebaruan (novelty), (2) memiliki kontribusi nyata, dan (3) disajikan dengan baik/presentasi artikel. Dalam technical note ini, 9 (sembilan) tahapan menyusun manuskrip disajikan sebagai bentuk sharing pengalaman penulis kepada para dosen dan peneliti, khususnya dosen muda dan peneliti pemula.
