Abstract

Yayasan Pendidikan Islam (YAPSI) Darussalam merupakan salah satu lembaga pendidikan yang menaugi Pondok Pesantren (PP) Darussalam yang berasa di desa Jatiguwi Kecamatan Sumber Puncung Kabupaten Malang. PP Darussalam merupakan pondok pesantren yang menaungi santri usia sekolah yang berasal dari keluarga prasejahtera mulai dari tingkat SD-SMP. Selain fokus pada pendidikan sekolah formal santri pada PP Darussalam juga dibekali dengan pelajaran keagamaan Islam dan kewirausahaan untuk membekali dan membantu perekonomian para santri. Salah satu bidang kewirausahaan yang dikembangkan untuk ketahanan ekonomi santri adalah usaha dibidang pembudidayaan jamur tiram. PP Darussalam mempunyai kumbung jamur seluas 4m x 4m dengan kapasitas 500 baglog, dengan hasil 2kg/hari. Hal ini bisa dibilang tingkat keberhasilannya kecil karena seharusnya bisa mendapatkan 4-6kg/hari, selain itu kapasitas masih bisa ditingkatkan sampai dengan 1000 baglog. Hasil analisa dari tim pelaksana PKM dan pihak pesantren menyebutkan kegagalan dalam budidaya jamur tiram disebabkan karena perawatan kumbung jamur tidak maksimal karena semua dilakukan secara manual.Oleh karena itu dibutuhkan alat otomasi kendali kelembaban pada budidaya jamur tiram. Alat yang dibuat mempunyai empat (4) mode yaitu:1 mode full otomatis dan 3 mode semi otomatis. Mode-mode yang dibuat agar alat dapat bekerja sesuai dengan perubahan kondisi lingkungan yang berbeda. Selain menghibahkan alat, pelaksanaan PKM ini juga memberikan pelatihan kepada pengelola pondok berupa pelatihan pengoperasian dan perawatan sederhana alat yang dihibahkan.

Abstract

Sterilization is the oyster mushroom cultivation process. Sterilization is used to kill nuisance microorganisms that can inhibit mushroom growth. The sterilization process is 8 hours at a temperature of 70–95 oC. This process of frequent breakdown is caused by the unstable temperature sterilization space and is controlled manually. Based on these problems, the right solution is to use a steamer that can be controlled automatically using the proportional–integral (PI) control method. PI controller consists of proportional gain and integral gain. To determine the value of proportional gain and integral gain, this study used the Ziegler-Nichols tuning method using the S curve. The results of the PI control parameters obtained the value of Kp=25.2 and Ki=0.302. Thus, producing a transient response graph with Mp=94.5; Os=0.45; PO=0.47; Tr=16,440 s. The system can work according to setpoint 95 oC and maintain a stable temperature according to the setpoint with these results. And the sterilization time becomes fast from 8 hours to 6 hours.

Abstract

Prayer time reminder based on raspberry pi with LCD TV as a display that not only can be set according to locationbased on GPS coordinates, but also contain information in the form of picture, text, video, etc. This is much betterthan just simple words placed on dot matrix or running text as it is today. Display design can be fully customized asper needed, it can be accommodated because the system based on raspberry pi mini PC. The method used for thisresearch is by conducting literature studies and field studies that are necessary for system design and manufacture.This system had several components involve include raspberry pi, signal jammer, air freshner, and LCD TV. Thisprayer time reminder display information of mosque name, address, clock, prayer schedule based on GPS coordinate,event photo, announcement, video, and running text as per installed program. This reminder also act as mobile phonesignal jammer, so there is no interference based on mobile phone signal. Jammer activated when entered prayer timeup to at least 30 minutes later. It function can also be added as air freshner which will spray as long as the jammer isactivated at 10 minute intervals.
