Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pupuk kotoran kambing terhadap pertumbuhan bibit tanaman pala di tanah aluvial. Penelitian dilaksanakan di kebun percobaan Fakultas Pertanian Universitas Tanjungpura Pontianak, sejak 23 November 2015 sampai dengan 8 April 2016. Penelitian ini menggunakan metode eksperimen lapangan dengan Rancangan Acak Lengkap yang terdiri dari satu faktor yaitu dosis pupuk kotoran kambing (m), dan 6 taraf perlakuan dengan 4 ulangan dan setiap satuan percobaan terdiri dari 3 tanaman sampel. Perlakuan tersebut adalah tanpa pemberian pupuk kotoran kambing (m0), 250 g/ polybag setara dengan 5% pupuk kotoran kambing (m1), 500 g/polybag setara dengan 10% pupuk kotoran kambing (m2), 750 g/polybag setara dengan 15% pupuk kotoran kambing (m3), 1000 g/polybag setara dengan 20% pupuk kotoran kambing (m4) dan 1250 g/polybag setara dengan 25% pupuk kotoran kambing (m5). Variabel pengamatan dalam penelitian ini adalah pertambahan tinggi tanaman, pertambahan jumlah daun, volume akar dan berat kering tanaman. Hasil penelitian menunjukkan bahwa pemberian pupuk kotoran kambing memberikan pengaruh nyata terhadap variabel pertambahan tinggi tanaman pada bibit tanaman pala, sedangkan pada variabel pertambahan jumlah daun, volume akar dan berat kering tanaman berpengaruh tidak nyata. Penambahan pupuk kotoran kambing menghasilkan pertambahan jumlah daun, volume akar, dan berat kering yang sama dengan tanpa penambahan pupuk kotoran kambing.

Abstract

Oyster mushrooms are an agricultural commodity whose cultivation process still has obstacles that must be resolved, namely, the difficulty of cultivators in regulating the temperature and humidity in the oyster mushroom cultivation room. Usually oyster mushroom cultivators will water the cultivation room at certain times without considering the temperature and humidity conditions. so it can cause the room to have abnormal humidity values. To overcome this problem, a device was created that can water automatically by considering the temperature and humidity conditions in the cultivation room. This device consists of an ESP32 microcontroller, an SHT22 sensor which can read room temperature and humidity, a sprayer to spray water, and a fan whose job is to maintain the room temperature and humidity. The ESP32 device will be programmed to control two Single State Relays which function to turn the sprayer and fan on and off, based on temperature and humidity readings from the SHT22 sensor. The results of the research show that the designed device is able to maintain ideal temperature and humidity conditions for oyster mushrooms to grow, namely: The temperature value is in the range of 30°C - 35°C and humidity is between 70% - 100%.
