Abstract

Extreme weather incidents refer to high rainfall and strong winds have been speculated to be detrimental on rice production. However, researches on the local adaptation to their impact on rice production are limited especially on tropical region like Indonesia. A study was conducted in Pesawaran, West Lampung, North Lampung, and Bandar Lampung using time series data of 2000-2015 and ground checking during extreme weather and normal seasons and its implication on sustainable management. Data were evaluated using multivariate regressions. Results demonstrated that the impact of extreme weather on the reduction of rice production was weak, 0.92%. Shifting on rice production among swampy, irrigated, and dry lands at which covered area of 13.67%, 42.69% and 43.65%, respectively, minimized the impact of the extreme weather. During limited precipitation, irrigated and swamplands had 2.5-3.0 times cropping intensity. Conversely, during La-Nina with excess precipitation, cropping in irrigated and drylands increased by 20 and 58%, respectively. Moreover, the local government maintained annual production improvement by about 5% through expansion of irrigated land, high yielding varieties and inputs subsidies. Considering that incident of extreme weathers tended to occur more frequently, consequently, planting calender utilization and rice variety adapted should be implemented.

Abstract

The increasing need for food is not in line with the clearing of agricultural land for food crops. So that the effort to increase the productivity of agricultural products is by applying precision agriculture. However, in reality, precision agriculture is difficult to apply to conventional processes, where farmers come to the farm, collect data, then carry out maintenance. This method will make production results not optimal because maintenance is not done accurately. This study introduces a monitoring system for environmental conditions based on the Internet of Things (IoT) for agricultural land, where trials are carried out in a greenhouse. The system that has been developed consists of several sensors designed to collect information related to agricultural environmental conditions, including DHT22 sensor (temperature and humidity), DS18B20 sensor (soil temperature), soil moisture sensor (moisture content in the soil), and BH1750 sensor (light intensity). Based on the Message Queuing Telemetry Transport (MQTT) protocol, the data is sent to a gateway (Raspberry Pi) and a local server via a wireless network to be stored in a database. By using the Node-RED Dashboard, the received sensor data is then displayed on the browser every time the sensor sends data. In addition, the local server also publishes sensor data to the public MQTT broker so that sensor data can be accessed through the MQTT Dashboard application on a smartphone. The results of testing for 25 days of the system running obtained an average success of the system in storing data of 99.64%.
BIMBINGAN TEKNIS PEMURNIAN GENETIK BENIH PADI MENTIK SUSU PADA KELOMPOK TANI MULTI BALIWO, DESA PURWOKENCONO, SEKAMPUNG UDIK, LAMPUNG TIMUR Jaenudin Kartahadimaja; Eka Erlinda Syuriani; Anung Wahyudi; Sri Handayani; Siti Novridha Andini

Abstract

Lampung Timur adalah salah satu kabupaten yang menyumbang produksi 628.000 ton gabah kering giling.  Kelompok Tani Multi Baliwo merupakan Kelompok Tani  penghasil padi yang berada di Desa Purwokencono, Kecamatan Sekampung Udik,  Kabupaten Lampung Timur, Provinsi Lampung.  Sehari-hari kelompok Tani Multi Baliwo melakukan kegiatan usaha memproduksi padi yang dibudidayakan secara organik.  Masalah yang saat ini dialami oleh Kelompok Tani Multi Baliwo adalah varietas padi Mentik Susu yang mereka tanam secara genetik tidak murni lagi.  Masalah ini sulit diselesaikan karena mereka tidak punya pengetahuan dan keterampilan tentang pemurnian genetik benih. Tujuan pengabdian adalah membekali khalayak sasaran dengan pengetahuan dan keterampilan teknik pemurnian benih padi mentik susu yang secara genetik sudah terkontaminasi. Untuk meningkatkan penguasaan materi secara teori, metode yang digunakan adalah melalui ceramah dan memperlihatkan beberapa foto atau gambar kegiatan pemurnian benih padi di lapangan.  Untuk memudahkan alih penguasaan keterampilan pemurnian benih di lapangan kepada  khalayak sasaran, maka digunakan metode bimbingan teknis dan pembuatan demplot tentang pemurnian benih padi mentik susu di lahan milik petani dan melakukan kunjungan ke lahan Teacing Farm milk Program Studi Teknologi Perbenihan Polinela. Hasil pengabdian menunjukkan semua khalayak sasaran (100%) terjadi perubahan penguasaan pengetahuan dari tidak tahu dan tidak mengerti menjadi tahu dan mengerti tentang cara pemurnian benih padi. Hasil pemantauan lapangan, 100% peserta pengabdian bisa menerapkan teknologi pemurnian benih padi yang secara genetik mengalami kontaminasi. Kata Kunci:  pemurnian genetik, padi mentik susu
