Sistem Humidifier dan Temperaturizer Digunakan dalam Penyiraman Otomatis Tanaman

Kurang atau berlebihnya kelembaban dan suhu dapat menyebabkan tanaman rusak atau bahkan mati. Untukmengurangi faktor human error yang sering terjadi dalam menjaga kelembaban dan suhu tanaman agar tumbuhsempurna diperlukan alat yang secara otomatis menjaga kelembaban dan suhu lingkungan disekitar areatanam.Metodologi pembangunan sistem menggunakan metode v sommerville. Sensor yang digunakan adalah sensor suhu Sensirion SHT-11. Relay yang digunakan adalah Relay Board DT I/O 1210 Delta-Electronic. Mikrokontroler yang digunakan adalah ATmega8535 16PU PDIP. Software Code Vision AVR versi 2.03.4 digunakan untuk kegiatan pemrograman (compile dan build) serta penginjeksian program ke mikrokontroler (via AVR ISP cable). Program yang digunakan berformat Bahasa C yang kemudian di terjemahkan ke bahasa assembler (format HEX dan ROM) dengan codevision. User-System Interface dibangun dengan Microsoft Visual Basic 6. Sistem bekerja secara mandiri tanpa intervensi atau input dari user. Input dari user hanya berupa kode program yang diinjeksikan ke mikrokontrol yang berguna untuk memprogram sistem, yakni untuk menentukan ambang batas derajat suhu (dalam celcius) dan kelembaban (dalam %) yang diinginkan. Bagian output sepenuhnya akan ditangani oleh mikrokontroler, yakni berupa otomasi on/off pompa air untuk melakukan aplikasi penyemprotan air via sprinkler yang bertujuan untuk menjaga kelembaban suhu lingkungan sekitar area tanam

Seleksi Kacang Bambara (Vigna Subterranea (L.) Verdcourt) Berumur Genjah Hasil Iradiasi Sinar Gamma Generasi M2

Mutation breeding using gamma-ray irradiation is one way to improve thevariability of bambara groundnuts. Improved variability can increase the effectiveness of selection on bambara groundnuts. The objective of this research was to obtain some genotypes of bambara groundnut of M2 generation that are of early maturity and high yield from gamma-ray irradiation through phenotypic selection. The experimental design was Spatial Plan, using the descriptive-comparative method. Bambara groundnuts accessions (KB-29 (1)) were treated with gamma-ray irradiation with different doses namely 100 Gy, 150 Gy, and 200 Gy. The results of this study showed that the phenotypic variability of the population irradiated by gamma rays 100 Gy, 150 Gy, and 200 Gy on the character of flowering time, harvest time, and all yielding ability characters was broad. The results of selection obtained 30 of the best genotypes that have advantages in the character of early maturity based on scoring value

The Phonology of Landawe Language

This study aims at investigating the phonology of Landawe Language. The data collecting was done by participant speaking and scrutinizing methods. It was analyzed using apportioned methods. Landawe language has 10 vowel sounds, but there are only five sounds proved as vowel phonemes, they are /i, a, e, o, u/. Besides, Landawe language has 18consonant sounds, they are:/b/, /p/, /d/, /t/, /g/, /k/, /ŋ/, /m/, /n/, /s/, /h/, /l/, /r/, /c/ /y/, /j/, /w/, and /ʔ/. Those consonant sounds are proved as the phoneme. Based on the distribution of the consonant, there is not any consonant that places the final position. They just place the initial and the medial of the word, except /ʔ/ and /y/that only place the medial position, and /j/ that only place the initial position. It means that Landawe language is categorized as vocalist language

PENERAPAN TEKNOLOGI JARINGAN SENSOR NIRKABLE UNTUK PEMANTUAN KADAR OKSIGEN DALAM KEMASAN EMBEDDED SYSTEM

This research aims to monitor oxygen levels using Wireless Sensor Network / JSN technology. The process ofsending oxygen content data is carried out in real time and continuously. The results of this study there are two parts,namely oxygen level control devices and oxygen content data delivery systems. Performance The oxygen level controldevice works well with an accuracy rate of 90%, and the maximum data transmission range is 60 meters. This device isequipped with displays and databases that are monitored stored in the data base. All device components are integrated inembedded system packaging. The benefits of the results of this study can be used to monitor oxygen levels in ponds or infish ponds, thereby increasing the yield and quality of harvested milkfish and shrimp ponds
