Menjes is an food that was made by tofu pulp. In order to be made a menjes chis, it must be dried as dry as possible. In this research, it'll develop a menjes dryer with variation of heat and time in order to calculate the efficiency of the dryer. The results, drying process using menjes dryer was faster than ordinary process. If menjes dried by sunlight, it need 3 hour to decrease 14% of water level inside menjes, but if menjes dryed by menjes dryer it only need an hour to decrease 12,33% water level using T=40 0 C heat source temperatur and 8.6% using T=50 0 C.

The existence of cooperatives is expected to be able to realize a populist economy that grows rapidly and is just and in accordance with the goals of sustainable development (SDGs). The participation of members of the Kosayu Credit Cooperative is still considered insufficient. This can be seen from the decrease in the number of members' savings and an increase in Non-Performing Loans (NPL) or members' bad loans. The purpose of this study was to determine the effect of cooperative members' motivation, benefits for members, and cooperative service quality both partially and simultaneously on the participation of Kosayu Kopdit members. The population in this study were all members of the Kosayu Kopdit. From the partial hypothesis testing, it is known that the cooperative motivation variable has a positive effect of 16.4%, the member benefits variable has an effect of 36.2%, and the service quality variable has an effect of 21.7% on the participation of Kosayu Kopdit members. While simultaneously, the variables of motivation to cooperate, the variables of benefits for members, and the variables of service quality jointly affect member participation by 40.4% and the remaining 59.6% is influenced by other factors.

Kulit pisang merupakan limbah dari buah pisang yang melimpah dan masih jarang dimanfaatkan. Kulit pisang sementara ini hanya digunakan sebagai pakan ternak atau dibuang begitu saja yang dapat menimbulkan masalah lingkungan, sehingga diperlukan penelitian lebih lanjut untuk dapat meningkatkan nilai guna dari limbah kulit pisang. Selain dimanfaatkan sebagai bahan baku pada makanan, kulit pisang bisa juga memperbaiki kandungan gizi bila diolah menjadi makanan. Sasaran pengabdian ini bersama Kelompok Tani “Anggrek” Desa Pagelaran Kecamatan Pagelaran Kabupaten Malang. Tujuan kegiatan ini adalah menjadikan limbah kulit pisang sebagai produk olahan menjadi kerupuk kulit pisang, sehingga menjadi produk pangan yang lebih awet, murah, mudah dikonsumsi, mempunyai nilai jual tinggi serta penyuluhan tentang pemasaran produk online.

In line with the development of thin film technology, its also developing plasma-based removal techniques such as plasma ashing. Plasma is an ionized gas-like phase. Ionized gas when the temperature approaches or exceeds atomic ionization energy. The atoms are the ionized into positive and negative ions. The purpose of this research to analyze the working system of plasma generation using 2,45GHz microwaves. The plasma reactor was successfully operate, but it only maintain to generate plasma in short time. The reactor broke because it couldn't hold the bombardment energy of particles which the energy was 1,623x10-24 for each every second. At last, the reactor could maintain the plasma only for ±240 s.

ABSTRAKTelah dilakukan penelitian pengaruh laju alir gas pada proses plasma etching di atas permukaan kristal SiO2. Proses plasma etching SiO2 dilakukan dengan menggunakan reaktor plasma model capacitively coupled plasma (CCP). Plasma dibangkitkan dengan daya 100 W menggunakan generator AC berfrekuensi rendah dengan menggunakan gas CH2FCF3. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh dari perubahan aliran gas terhadap laju etching pada permukaan SiO2. Laju alir yang digunakan pada rentang 20 -40 mL/min di mana parameter lainnya dibuat tetap. Profil permukaan SiO2 yang teretching dianalisa menggunakan white-light profilometer (Topography Measurement System (TMS 1200 Micro Lab)). Hasil penelitian menunjukkan proses etching pada permukaan SiO2 dipengaruhi oleh mekanisme secara fisis dan reactive ion etching (RIE) di mana pada laju aliran gas rendah mekanisme secara fisis lebih dominan sedangkan pada laju aliran gas tinggi dipengaruhi oleh mekanisme RIE. Laju etching maksimum yang diperoleh 7,753 nm/min dicapai pada proses plasma etching.Kata Kunci: plasma etching; laju etching; RIE; QCM ABSTRACT Effect of gas flow rate on the surface of quartz crystal SiO2 during plasma etching was studied. The etching process was applied using the capacitively coupled plasma (CCP) reactor generated with 100 W power AC generator at low frequency of 40 kHz using a gas flow of CH2FCF3. The main objective of this study was to determine the effect of changing gas flow rate on the plasma etching rate on the SiO2 surfaces. Gas flow rate was varied between 20-40 mL/min, while keeping all other plasma parameters constant. The etched surface of SiO2 was analyzed using white-light profilometer (Topography Measurement System (TMS 1200 Micro Lab)). The results show the physical etching processes influenced the rate of etching at a low gas flow rate, while the higher flow rate influence reactive ion etching (RIE) in the etching process. The maximum etching rate is found at 7.753 nm / min achieved in plasma etching process.
