Abstract

Oldeman agroclimate zone is a classification system used to group areas based on rainfall distribution patterns and soil moisture potential available throughout the year. This system provides a clearer picture of which areas are suitable for certain crops based on their water needs, as well as optimizing the use of existing climate resources through cropping patterns arrangements. This study aims to identify and analyze Oldeman agroclimate zones to determine the right planting season and develop efficient food crop cropping patterns on Kisar Island. This study combines two approaches, namely descriptive and quantitative with the following analysis stages: generating rainfall data, calculating average regional rainfall, determining agroclimate zones, determining planting seasons, and arranging cropping patterns. The results of the study indicate that Kisar Island is included in Agroclimate Zone E3 with a planting season length of 7 months, starting in December and ending in June. Intercropping or mixed cropping patterns are options in corn and legume cultivation. To avoid water shortages during the reproductive phase of the plant, dryland rice planting should be carried out in the period from March to June.

Abstract

The research was carried out in Feruni Village, South Aru District, Aru Islands Regency, from September to November 2021. This study aims to determine the potential and utilization of sago plants (Metroylon sp) in Feruni Village, South Aru District, Aru Islands Regency. The method used was a survey, and field data was collected by using questionnaires and FGD. Twenty respondents of sago’s farmers were randomly selected, and data obtained were descriptively and quantitatively processed to calculate density, frequency, dominance, and the important value index. The results showed that there are 3 types of sago in Feruni Village, South Aru District, Aru Islands Regency, namely Molat Sago (Metroxylon sagus Rottb), Tuni (Metroxylon rumphii Mart.), and Ihur (Metroxylon sylvestre Mart.). Traditional tools such as axes and machetes are used by people in Feruni village to harvest sago after putting it into the gutter, while sago leaves are used for roofs, the woven tumang sago sheath is used for seats, and the sago stems are used for firewood. There are 4 types of processed sago flour products, namely Papeda, Pompom, Sinoli, and Jepa-jepa, and based on basic ingredients, they can be divided into 2 main groups: raw (wet) and dried sago flour.

Abstract

The experiment aimed to investigate the allelopathic effects of active compounds present in broadleaf weeds Ageratum conyzoides and Borreria alata. The study also sought to assess the viability of various seed varieties grown using allelopathic extracts from these weeds, varying in concentrations of tannins and phenols. The research findings revealed that methanol extracts exhibited potent allelopathic properties, inhibiting germination, radicle and hypocotyl growth, as well as reducing the germination rate of soybean seeds. B. alata weed extracts demonstrated lower allelopathy than A. conyzoides, suggesting a possible alteration in the active compounds (allelochemicals) present due to a reforming process. Extracts from both A. conyzoides and B. alata weeds inhibited root length, hypocotyl growth, and germination across a range of concentrations, from low (10% v/v) to high (30% v/v).

Abstract

Musim tanam akan semakin pendek karena berkurangnya ketersediaan airtanah akibat fenomena El Nino. Dalam konteks ini, telah dilakukan penelitian yang menggambarkan kejadian, intensitas, dan frekuensi peristiwa El Nino serta mengkaji pengaruhnya terhadap neraca air jagung di Pulau Babar. Data iklim, koefisien tanaman jagung, ENSO History, dan data pendukung dikumpulkan untuk selanjutnya dianalisis. Analisis data diawali dengan pembangkitan data curah hujan, dilanjutkan dengan analisis kondisi curah hujan El Nino, dan analisis neraca air lahan jagung. Berdasarkan hasil penelitian, di Pulau Babar telah mengalami delapan episode El-Nino, rata-rata setiap empat tahun selama tiga puluh tahun terakhir. Jagung dapat ditanam dua kali setahun di Pulau Babar pada kondisi curah normal atau rata-rata, dan hanya bisa ditanam setahun sekali saat terjadi El Nino

Abstract

The rambutan plant (Nephelium lappaceum) is a tropical fruit of the Sapindaceae family that is loved by the Indonesian people and is widely found in various regions, including Hitu Village and Allang Village, Central Maluku Regency. Rambutan production in this area tends to decrease every year, one of which is due to weed disturbances that inhibit plant growth. This study aims to identify the types of weeds that grow in the rambutan planting area in Hitu Village and Allang Village and determine the most dominant weed types in each location with different altitude conditions. The research was carried out using a vegetation survey method using sample plots measuring 1 m × 1 m under six rambutan trees in two different areas, so that a total of 12 weed samples were obtained. Data collected through field observation includes quantitative and qualitative data, both primary and secondary. The results of the study showed that there were 27 types of weeds in the entire rambutan planting area, namely 15 types in Hitu Village and 13 types in Allang Village. The dominant weed type in Hitu Village is Vigna luteola with an SDR value of 18.56%, while in Allang Village the dominant weed is Miconia crenata (Cahs) Michelang with an SDR value of 28.89%.
