Abstract

Achievement level of input use efficiency will determine the success of farmers in achieving maximum production and income from farming and agro patchouli and can compete in the market. The research aimed to analyze system of patchouli agroindustry conducted from production technology, input using, cost, production, income and patchouli agroindustry efficiency and marketing sub-system conducted from channel, marketing organization, cost, profit and marketing efficiency in Guo Batu Village, Mandailing Natal Districk, North Sumatra Province. Census method used in this research with 30 farmers as sampling. The average of agroindustry sub-system production 116,70 kg of patchouli oil per production process, gross income Rp. 64,185,000 and net income Rp. 41,453,091.67. family income Rp. 45,185,076.53 and RCR 2,90. The conclusion is the marketing doesn’t have problem because the farmers sell the patchouli in oil directly to traders with the price Rp. 550,000/kg.

Abstract

Both oil palm plantations boerdering forests and oil palm plantations bordering rubber plantations were studied using purposive random sampling with pit fall traps, sweep nets and yellow pan traps. Species biodiversity was analyzed using the Shanon-Wienner index and the Simpson index. The dominant species was determined using the Important Value Index. This study found 1,683 individuals, 7 orders and 18 families of predatory and parasitoid insects. The Shanon-Wienner diversity index was 2.78 for oil palm plantations adjacent to forest and 2.62 for oil palm plantations adjacent to rubber plantations. While the Simpson diversity index was 1.00 for oil palm plantations adjacent to forest and 0.94 for oil palm plantations adjacent to rubber plantations. The Order Hymenoptera Family Formicidae had the highest Important Value Index (0.58 for oil palm plantations bordering forest and 0.62 for oil palm plantations adjacent to rubber plantations).

Abstract

The soil physical properties are one of the components of soil fertility that function as a place for roots to penetrate. Different types of land uses affect the soil physical properties, especially on the availability of water and soil aeration which indirectly affects the availability of nutrients in the soil. Research on the soil physical properties of ex-gold mining, oil palm plantations and forests was carried out on Ultisol located in Tebing Tinggi Village, Dharmasraya Regency from April until October 2021. The objective of this study was to obtain the comparison of soil physics properties in ex-gold mining land with oil palm and forest land on Ultisol. The method on this study was a survey with purposive sampling on three different land uses (ex- gold mining land, oil palm land and forest) at a depth of 0-20 cm and 20-40 cm and it was replicated 3 times. The observed parameters were soil texture, organic matter, volume weight, soil pore space, soil water content, permeability, and soil aggregate stability. Based on soil analysis in the laboratory, it was obtained that the physical conditions of the soil in three different land uses, i.e the physical condition of the oil palm land and forest were better than the ex-gold mining land. The soil texture on ex-gold mining land was classified on sandy clay loam and sandy loam with a very low organic matter content (0,20-1,72 %) if compared with oil palm and forest land. The volume weight in each land use was relatively high with the total soil pore space was low except in oil palm land depths of 0-20 cm, which is 69,93 % vol (moderate). Permeability was slow to moderate with the soil aggregate stability classified as unstable to steady. Soil water content was relatively low except in forest land depths of 20-40 cm which very high criteria (33,93 %).

Abstract

Rapid development of oil palm plantations in Indonesia, cause seeds requirement also increase. Nurseries are a phase that is very vulnerable to pests and diseases because the morphological sensitivity of the seedlings which are very responsive. The main pests that attack oil palm in nursery are nocturnal beetles. The objective of this study was to determine the species, population and percentage of crops attacked by the nocturnal beetles in the main nursery phase oil palm (Elaeis guineensis Jacq.). This research was conducted at the CV. Agro Unggul Sejati located in Sungai Kambut Village, Pulau Punjung District, Dharmasraya Regency. The method on this study was a survey. The sample plants were determined systematically, there were 10% of the total number of seeds in each observation block. The trapping of nocturnal beetles was carried out by light traps were installed two traps in each observation block. Observation of the percentage of affected crops was carried out by counting the sample plants that were attacked and vice versa. Two types of nocturnal beetles were found in oil palm main nursery in CV. Agro Unggul Sejati, namely Apogonia expeditionis Ritsema and Adoretus compressus Webb. Morphological characteristics of A. expeditionis are shiny black and sized 8,5-11 mm while A. compressus is reddish brown, with a body length ranging from 1-1,5 cm. The attack of nocturnal beetle cause large tears in the leaves of oil palm seedlings. The population of A. compressus was more abundant than A. expeditionis. There were 45 species of A. compressus, while 29 species of A. expeditionis. The percentage of affected crops caused by the nocturnal beetles in oil palm in the main nursery ranged from 11,12-37,03%.

Abstract

Exploration and characterization of germplasm is an important stage in plant breeding activities. The present research was about exploration and morphological characterization of cacao (Theobroma cacao L.) in smallholder plantations in Koto Salak Sub-district, Dharmasraya Distric. It was carried out on July until October 2021. The objectives of this study were to characterize the morphology of cacao crops in Koto Salak Sub-district, Dharmasraya District and to determine the diversity level of cacao crops in that area. This research was by a survey method, with purposive sampling. The technique for data collection was by observe the morphology of the plants in each sample. The obtained data were analyzed descriptively, and for the similarity analysis, statistical calculation was by the NTSYS Ver 2.02 program. The research results obtained 4 variants of cacao plants which collected from 5 villages namely Padukuan, Pulau Mainan, Simalidu, Koto Salak, and Ampalu. Researcher obtained 30 samples of cacao plants which characterized by 16 characters, characters were wide variability and 14 other characters narrow variability with the level of diversity ranging from 39-77%.

Abstract

Pertumbuhan tanaman kakao sangat dipengaruhi oleh ketersediaan unsur hara di dalam tanah. Ketersediaan unsur hara ditentukan oleh sifat fisik, kimia dan biologi tanah. Pada tanah marginal seperti Ultisol memiliki tingkat ketersediaan unsur hara yang sangat rendah. Hal ini disebabkan oleh proses pelapukan yang intensif. Oleh karena itu, perlu dilakukan perbaikan kesuburan tanahnya. Salah satu upaya yang bisa dilakukan untuk memperbaiki kesuburan tanah Ultisol agar kakao dapat tumbuh dengan baik adalah dengan melakukan penambahan pupuk alam. Pupuk alam dapat berasal dari pemanfaatan sisa-sisa tanaman atau hewan. Salah satu diantaranya yaitu pemanfaatan limbah darah sapi, limbah ini belum banyak digunakan sebagai sumber pupuk alam. Penelitian ini dilaksanakan pada bulan November 2019 hingga April 2020, yang bertempat di kebun percobaan kampus 3 Universitas Andalas, Dharmasraya. Penelitian ini merupakan penelitian eksperimen yang disusun dalam Rancangan Acak Lengkap (RAL). Perlakuan yang dicobakan terdiri dari 5 taraf perlakuan yaitu: P0: 0 ml darah/L air P1: 40 ml darah/L air, P2: 60 ml darah/L air, P3: 80 ml darah/L air, P4: 100 ml darah/L air. Dari hasil penelitian diketahui bahwa penambahan pupuk cair darah sapi memberikan pengaruh terhadap pertumbuhan bibit kakao pada ultisol. Aplikasi pupuk cair darah sapi dengan dosis 40 ml – 100 ml pada tanaman kakao memberikan respon pertumbuhan yang lebih baik pada tanah ultisol, jika dibandingkan dengan tanaman yang tidak ditambahkan pupuk cair darah sapi. Hal ini dapat dilihat pada variabel pengamatan jumlah daun dan diameter batang. Dengan demikian pemanfaatan limbah darah sapi dapat dipertimbangkan sebagai salah satu sumber pupuk cair alami.
