Abstract

Amount of water that obtained soil depend on soil ability to quick absorp and continue water accepted from soil surface. Water holding capacity of soil are influenced by soil texture and organic matter. The purpose of th is research was to study soil water holding capacity on two textures of soils l.e. clay, and clay loam by organic matter application of chicken manure and compost. Those treatments were control, combined of chicken manure different texture soils, and combined of compost different texture soil. Chicken manure and compost application consisted of two levels of 30 9 5 kg-l soil texture and 50 9 5 kg-l soil texture, respectively. Soil texture consisted of two kinds l.e, clay, and clay loam. The research was analyzed according to descriftive method. Result of this research indicated that the highest available water capacity of 17.352 % was given by combined t reatment of 50 9 compost of 5 kg clay textured soils. The lowest evaporation rate had occur at clay texture soils.

Abstract

The objective of this research was to evaluate the response of six upland rice cultivars from East Kalimantan over different plant spacing. The experiment was conducted at Kutai Kartanegara district in East Kalimantan, Indonesia. The experimental design used was the factorial experiment in Randomized Completely Block Design (RCDB) with three replications. The first factor was six upland rice cultivars of East Kalimantan, i.e.: v1 (Mayas Pancing), v2 (Gedagai), v3 (Bogor Putih), v4 (Mayas Putih), v5 (Serai) and v6 (Kunyit). The second factor was plant spacing i.e.: j1 (20 x 20 cm) and j2 (30 x 30 cm). The results showed that among the six cultivars, Gedagai, Bogor Putih and Kunyit produced higher yield than other varieties.  Gedagai and Bogor Putih cultivars produced higher yield of 2.99 ton ha-1 at plant spacing 20 x 20 cm, whereas Kunyit produced higher yield of 2.66 ton ha-1 at plant spacing 30 x 30 cm. The agronomic characters showed that plant height of the six cultivars differed significantly at harvest time. In addition, highly significant differences of harvest time were observed of the six cultivars.Doi: http://dx.doi.org/10.12777/ijse.4.2.2013.66-68

Abstract

The objective of this researchis identification local low land rice cultivars explored based on morphological and agronomical character from East Kalimantan. This research used single plot and single plant method. The data were then analyzed by computerized Cluster Analysis. Research result showed identification stalk and plant heightwas found that most cultivar were medium height ( 130 cm), medium stalk diameter (5-7 mm), large amount of tillerand productive tiller ( 25 tillers). Identification on morphological character or traits of ligule and leaf showed that all cultivars had colorless or white and split-shaped ligules, light green collars, and light green auricles. Most of them had ligules of medium length ( 20 mm), leaves of medium length ( 61-80 cm), narrow leaf width (1-2 cm), smooth leaf surface, and green colored leaves.The results of identification on morphological traits of panicle and grain showed that any cultivar have axis of panicle floppy and that a greater part of the cultivars had long panicles (25 cm), compact and straggle or dense panicles, relatively large amount of secondary branches, panicle position is a little above the flag leaf, rice grain most of which were tilled with yellow strawcolor, stigma of rice with yellow strawcolor, head pistil with white color, palea lemma with yellow strawcolor, lemma sterile turn yellow straw color with sterile length of lemma in short criterion.The result of cluster analysis combination of all existing traits or character indicated that 26 local low land rice cultivar of East Kalimantan identified there were not found cultivarsof 100 % similar.Keywords: identification, local cultivar, low land rice, Agronomy, Morphology

Abstract

The need for electrical energy is increasing in every area and year. However, not all sites can be fulfilled - incredibly outlandish locations. At the same time, the natural potential in there, such as river irrigation flows, can be used as an additional source of electricity for the area. This paper describes the science and technology-based community service activities by applying appropriate micro-hydro technology to produce electrical energy. This service aims to optimize natural potential in the form of rice field irrigation channels as street lighting in Rindu Hati Village, Central Bengkulu Regency. The methods are socialization and design of micro hydro systems with service participants. The service implementation consists of equipment preparation, socialization, and installation of a micro-hydro system with service participants from members of a group ‘Pokdarwis’ of the Rindu Hati Village. The involvement of participants with the service team made this activity possible to carry out properly so that street lighting with energy sources from irrigation channels could be realized. Monitoring the condition of the sustainability of the micro-hydro system was still carried out by appointing one of the service participants as the person in charge of the micro-hydro system.  ---  Kebutuhan masyarakat terhadap energi listrik setiap tahun terus meningkat. Namun tidak semua daerah dapat tercukupi kebutuhan listriknya, terutama untuk daerah yang terpencil, sedangkan potensi alam di daerah terpencil seperti aliran irigasi sungai dapat dimanfaatkan sebagai sumber listrik tambahan bagi daerah tersebut . Tulisan ini memaparkan kegiatan pengabdian masyarakat berbasis iptek melalui penerapan teknologi tepat guna mikrohidro dalam upaya menghasilkan energi listrik. Tujuan pengabdian ini  untuk mengoptimalkan potensi alam berupa saluran irigasi sawah sebagai penerangan jalan Desa Rindu Hati, Kabupaten Bengkulu Tengah. Metode yang digunakan adalah sosialisasi dan rancang bangun sistem mikrohidro dengan peserta pengabdian. Pelaksanaan pengabdian terdiri dari tahapan persiapan perangkat, sosialisasi dan instalasi skistem mikrohidro dengan peserta pengabdian yang berasal dari anggota Pokdarwis Desa Rindu Hati. Hasil dari kegiatan ini adalah terbentuknya sistem mikrohidro yang memanfaatkan aliran irigasi sungai sehingga dapat dimanfaatkan sebagai sumber penerangan lampu jalan di lokasi tersebut.Pemantauan kondisi keberlangsungan sistem mikrohidro tetap dilakukan dengan penunjukkan salah seorang peserta pengabdian sebagai penanggung jawab sistem mikrohidro.
