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

Penghalusan bonggol jagung menggunakan metode manual umumnya membutuhkan waktu lama serta penggunaan motor belum mampu memberikan kecepatan yang sesuai dan kurang stabil. Putaran motor yang tidak stabil mempengaruhi tingkat presisi dalam proses penghalusan da tigkat kehalusan tiap sisi. Penelitiaan ini dilakukan dengan tujuan menjaga keseimbangan putaran motor agar bonggol yang dihasilkan lebih presisi dan mempersingkat waktu produksi. Kontrol PID merupakan metode yang cocok untuk mengatur kecepatan putaran motor AC dikarenakan kemampuannya dalam memberikan respons yang cepat, tepat, dan konsisten terhadap perubahan dalam sistem pengendalian. Mikrokontroler yang digunakan adalah ESP32 yang berperan sebagai pengontrol dimmer TRIAC sesuai nilai setpoint yang ditetapkan dan Zero Crossing Detector sebagai pemicuan sudut fasa ketika terjadi persilangan nol serta sensor FC-03 untuk membaca kecepatan motor AC yang akan di umpan balik ke ESP32. Kontrol PID akan mengoreksi kesalahan kecepatan motor yang tidak sesuai dengan setpoint sehingga kecepatan lebih stabil. Setting parameter PID menggunakan metode tuning Ziegler Nichols 2 dengan memperhatikan karakteristik motor didapatkan nilai parameter PID yang sesuai yaitu Kp = 0,3, Ki = 0,15, dan Kd = 0,15 dengan setpoint 2600Rpm. System diujikan dengan parameter dan didapatkan respon system sebagai berikut nilai td = 4 detik, nilai Tr = 11 detik, nilai Tp = 16 detik, Tr = 20 detik, .

Abstract

Negara Indonesia adalah negara yang beriklim tropis, hanya ada dua musim yaitu musim panas dan musim hujan. Pada saat musim panas, sumber energi terbesar untuk mengeringkan pakaian adalah sinar matahari. Keterbatasan dalam mengeringkan pakaian membuat mereka sedikit kesulitan pada saat hujan berkepanjangan. Dalam permasalahan tersebut maka dilakukanlah perancangan lemari pengering pakaian dengan kipas, heater, exhaust fan untuk pengontrolan suhu dan kelembaban yang digunakan di laundry rumahan. Pada perancangan sistem kontrol suhu digunakan pengendali PID Controller (Proporsional-Integral-Derifativ) yang akan mengontrol pemanas (heater) pada lemari pengering pakaian. Dalam sistem pengendali PID Controller dapat berfungsi efektif pada nilai Kp = 3.6 , Ki = 0.9, dan Kd = 3.6 dengan kontrol suhu ±40°C. Sinyal kontrol tersebut digunakan untuk pengaturan tegangan AC pada driver heater dengan prinsip kontrol sudut fasa. Implementasi kontrol PID pada lemari pengering pakaian membuat heater bekerja lebih efektif dibandingkan dengan sistem kontrol tanpa menggunakan PID Controller. Dengan Sistem tersebut membuat respond heater bekerja maksimal dengan hasil lemari pengering pakaian dapat mengeringkan pakaian dengan waktu sistem bekerja selama 30 menit, 60 menit, dan 90 menit sesuai dengan tingkat ketebalan pakaian yang dikeringkan.
