ABSTRACT The results of reference studies in journals related to the potential of Trichoderma spp fungi in the application of sustainable agroecosystems can be reported that the best solution to overcome food safety and environmental problems is the application of biological control using Trichoderma spp. Its antagonistic properties with plant pathogenic microorganisms make it more reliable for use in agriculture. Several research results reported that Trichoderma spp is known to have the ability to attack other fungi so that it has the potential as a potential biological control agent. Secondary metabolites secreted by Trichoderma spp. has proven its role in suppressing the growth of pathogenic microorganisms and stimulating plant growth. Several research results reported that Trichoderma spp. as natural decomposition agent and bioremediation biological agent Key word: Trichoderma spp, sustainable agroecosystem, application

Desa Ngunut berada di wilayah Kecamatan Kawedanan, Kabupaten Magetan yang sebagian besar penduduknya menggantungkan hidup dari bercocok tanam. Berdasarkan data dari segi ekonomi, sebanyak 27% warga Desa Ngunut, Kecamatan Kawedanan merupakan keluarga pra sejahtera, sehingga diperlukan upaya untuk dapat meningkatkan perekonomian keluarga di wilayah mitra melalui pemberdayaan potensi warga. Salah satu upaya peningkatan perekonomian melalui pemanfaatan tanaman sereh yang berpotensi dikembangkan untuk mengembangkan usaha perekonomian dari hulu ke hilir akan tetapi belum menjadi komoditas di wilayah Desa Ngunut. Hal tersebut dikarenakan warga belum memahami manfaat dan potensi ekonomi dari tanaman sereh. Oleh karena itu kegiatan pengabdian kepada masyarakat ini dilakukan melalui penyuluhan untuk memperkenalkan manfaat dan potensi ekonomi tanaman sereh (Cymbopogon nardus). Luaran yang dicapai adalah peningkatan pengetahuan warga Desa Ngunut, Kecamatan Karangrejo, Kabupaten Magetan mengenai tanaman sereh (Cymbopogon nardus) yang dapat dimanfaatkan untuk meningkatkan perekonomian warga.

Metode untuk mengetahui distribusi suhu inkubator penetasan telur ayam adalah dengan metode analitik dari penyelesaian persamaan difusi panas pada inkubator penetasan. Karena inkubator penetasan berbentuk kotak berukuran dengan sumber pemanas kawat nikelin, penyelesaian persamaan difusi panas memanfaatkan persamaan difusi panas pada koordinat kartesian dan menggunakan metode pemisahan variabel. Untuk mendapatkan pola distribusi suhu dan melihat kemerataan distribusi suhu di dalam ruang penetasan telur, maka penyelesaian persamaan difusi panas pada inkubator penetasan divisualisasikan menggunakan software Matlab R2013a.Hasil dari penelitian ini menunjukkan bahwa pola distribusi suhu inkubator berfluktuasi berdasarkan fungsi waktu dan posisi. Pertambahan waktu menunjukkan bahwa suhu mencapai keadaan kesetimbangan (steady-state). Perbedaan posisi menunjukkan bahwa suhu memiliki nilai yang berbeda-beda dalam range (34,7-41,2) . Hasil pemerataan suhu ruang inkubator berdasarkan visualisasi dengan software Matlab R2013a menggambarkan bahwa distribusi suhu merata di dalam inkubator penetasan telur ayam dan pada sebagian besar titik diperoleh suhu ruang yang sesuai untuk penetasan telur ayam pada range (38,5-40,5).Kata kunci: difusi panas, inkubator penetasan telur, visualisasi, distribusi suhu.ABSTRACTThis research was aimed to (1) know the pattern of distribution of temperature of chicken egg hatching incubator (2) know of the evenness of distribution of temperature in the incubator made from ceramics, and (3) know the temperature of the walls of the incubator so that the distribution of temperature in the incubator spread evenly on the range of (38,5-40,5)℃.

Penelitian ini bertujuan untuk menganalisis kemampuan kerja dari beberapa komponen penggerak pada sistem pengaman pintu ber-password dan mengetahui unjuk kerja sistem pengaman pintu ber-password.Analisis komponen pada sistem pengaman ini meliputi analisis motor stepper beserta rangkaian kontrolnya dan analisis ulir daya. Analisis motor stepper meliputi pengujian torsi motor, kecepatan motor dan karakteristik masukan pada rancangan program, sedangkan analisis ulir daya digunakan untuk mengetahui torsi minimum yang dibutuhkan untuk memutar beban. Beberapa program yang digunakan untuk menganalisis komponen motor stepper adalah program Arduino dan program SpectraPLUS 5.0.Hasil penelitian menunjukkan bahwa torsi minimum yang dibutuhkan ulir untuk berotasi sebesar (0,036 ± 0,004) N.m, sedangkan torsi maksimum yang dihasilkan motor stepper sebesar (0,060 ± 0,003) N.m, sehingga dapat disimpulkan bahwa torsi yang dihasilkan motor stepper cukup untuk menggerakkan beban. Motor stepper diprogram dengan kecepatan putar sebesar 60 rpm yang tidak berpengaruh terhadap besar torsi motor melainkan mempengaruhi waktu rotasinya. Kecepatan 60 rpm dipilih karena lebih ideal dari kecepatan yang lain karena menghasilkan waktu yang lebih cepat saat menggeser pintu dan tidak menimbulkan kemacetan pada sistem. Hasil pengukuran menunjukkan bahwa motor stepper berotasi sebanyak 25 kali untuk menggeser pintu dan membutuhkan waktu sebesar (24,91 ± 0,01) s, sedangkan rotasi sebanyak 25 kali tanpa beban, akan membutuhkan waktu sebesar (24,14 ± 0,01) s. Dengan demikian disimpulkan bahwa beban mempengaruhi kecepatan motor.Kata kunci: kecepatan putar, torsi, motor stepper, dan ulir.This study aims to analyze the workability of several activators component of the passworded door security system and to find out the performance of door security with password system. Analysis of components of the safety system included analysis of stepper motor control and analysis of power screw. Analysis of stepper motor included testing the motor torque, the motor speed and the characteristics of the input on the design of the program, while the analysis of the power screw was used to determine the minimum torque required to rotate the load. Some programs used to analyze the component of the stepper motor were Arduino and SpectraPLUS 5.0.The results showed that the minimum torque required to rotate the screw was (0.036 ± 0.004) N.m, while the maximum torque produced by stepper motor was (0.060 ± 0.003) N.m, so it can be concluded that the stepper motor torque generated was enough to drive the load. Stepper motor was programmed with rotational speed of 60 rpms that did not affect to the motor torque but it influenced the time of rotation. Speed of 60 rpms was more ideal than the other speeds because it produced a shorter time to slide the door and did not cause congestion on the system. The measurement results showed that the stepper motor rotated 25 times to slide the door and took (24.91 ± 0.01) s, while the rotation of 25 times without a load, took time of (24.14 ± 0.01) s. Thus it could be concluded that the load affected the speed of the motorKeywords: rotational speed, torque, stepper motors, and screw
