Abstract

The plants surrounding rice field serve as a habitat and niche for entomophagous arthropods. This study aimed to identify the entomophagous arthropod species and to analyze their abundance and community in vegetables and refugia grown in the rice field. The field was surrounded by 4 species of refugia (Zinnia sp., Tagetes erecta, Cosmos caudatus, and Sesamum indicum) and 4 species of vegetables (Vigna unguiculata, Momordica charantia, Cucumis sativus, and Luffa acutangula). The arthropod found were 67 species of predatory arthropods and 22 species of parasitoids. The predatory arthropods were mostly found in rice (51 species) followed by Zinnia sp. (15 species), and M. charantia (9 species). Parasitoid species were dominantly found in rice (19 species), Zinnia sp. (7 species), and M. charantia (6 species). The predatory arthropods mostly found were Tetragnatha javana, Tetragnatha virescens, and Paederus fuscipes, while the dominant parasitoids were Cardiochiles sp., Elasmus sp., and Snellenius sp. The parasitoid species composition in rice was more similar to those in bitter melon and zinnia. The composition of predatory arthropod species in rice was similar to those in all vegetables and refugia, except in cowpea. Zinnia sp. and M. charantia were the most chosen habitat by entomophagous arthropods.

Efriandi E, Nurwahyudi MA, Ariadi Z, Karenina T, Defriyanti WT.  2022. Relationship between some physical properties of soil inceptisol post soil mining. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 1067-1072.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Research to know and observes change of morphology after done soil mining for brick industry. The purpose of this study is to find out and observe changes in the physical properties of the soil after taah mining for the brick industry.Research is done by observing 4 soil profile that is (1) soil that is not is mined (control); (2) soil which have been mined and leaved more than 10 years; (3) soil which have been mined and leaved ± 5 year; (4) soil which have been mined and leaved between 1-3 years. Inceptisol soil has limited physical properties for the development of the root system and soil roots, has a thin effective depth for tillage, has a larger density due to some of the pores filled with dust particles. Based on the distribution of each soil order on the earth's surface, inceptisols have an area of about 15% of the earth's surface area. Classified as fertile land for agricultural land. Result of research indicates that Inceptisol experience change of morphology soil colour, structure, consistency, root, horizon boundary. Inceptisol which has been mined for brick base material experiences change of morphology and soil physical properties. The need of doing of research that is further about land rehabilitation technique so that serve the purpose of consideration in doing repair of area ex-mined.

Abstract

Shallots are the important horticultural commodities that contribute to inflation but the level of production is still limited. Shallot cultivation is mostly carried out on Java and its development in other regions is limited. The purpose of the introduction of shallot technology was to motivate and empower the community in utilizing yard to meet needs and increase income. The implementation of shallot introduction activities was carried out through three main stages. There were of coordination consisting of initial survey activities with internal and external stakeholders, demonstration plot for shallot cultivation on the yard of business group members, and periodic monitoring and evaluation. From the introduction of shallot cultivation in the yard, it had increased the knowledge of business group Rawa Ijo Sematang Borang members in cultivating shallots and was able to motivate business group members in understanding the importance of utilizing the yard as productive land. From per 100 polybags planted with shallots with a total seed weight of 0.565 kg, a yield of 5.83 kg was obtained. Beside that, it could also reduce family consumption expenditure and increase household income.

Maryani, S., Novriadhy, D., & Karenina, T. (2024). The effect of peat soil compaction on physical properties at the Sriwijaya Botanical Gardens, South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 878–885). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The physical characteristics of the soil at each location are always different, especially for land that contains peat. The Sriwijaya Botanical Gardens of South Sumatra is a botanical garden on peat land with five functions, namely plant conservation, research, education, tourism and environmental services. These various functions will result in soil compaction which also affects the physical properties of peat soil, so research is needed to determine the effect of peat land compaction on the physical properties of the soil at the Sriwijaya Botanical Gardens of South Sumatra for planning the management of this land in the future. This research was conducted at the Sriwijaya Botanical Gardens in Bakung Village, Indralaya Utara District, Ogan Ilir Regency, South Sumatra Province with a peat land type. Soil sampling was carried out using a soil sample ring at a soil depth of between 0-20 cm. The sample points were determined as many as 20 points on a land area of 100 hectares. The parameters of the physical characteristics of the soil observed were bulk density, soil pore space and water content. Observations of the physical characteristics of the soil were carried out at the Laboratory of the Soil Department, Sriwijaya University. The results of the study showed that the physical characteristics at several soil sampling locations in the peatlands of the Sriwijaya Botanical Gardens of South Sumatra varied, influenced by the function of the land before and after development, the depth of the peat, and the distance of the location from the canal. The physical characteristics of the soil bulk density value at the location ranged from 0.15 to 0.38; the soil pore space obtained with an average value of 93.68% and the saturated water content ranged from 66.68% - 98%). It is hoped that the identification of the physical characteristics of this land can be used as a reference material in the planning and management of peatlands at this location in the future.

Abstract

Penggunaan hidroponik untuk produksi sayuran telah umum dilakukan. Namun penggunaan hidroponik untuk tujuan pembibitan tanaman sayuran belum banyak dilakukan meskipun secara penelitian cukup potensial. Oleh karena itu, tujuan penelitian adalah untuk mengetahui pengaruh pembibitan secara hidroponik terhadap pertumbuhan beberapa jenis sayuran. Penelitian dilaksanakan di Kota Palembang menggunakan 5 jenis sayuran cabai merah keriting, cabai rawit putih, cabai rawit hijau, terong ungu, dan tomat cherry. Penelitian menggunakan rancangan acak kelompok dengan 3 perlakuan berupa pembibitan hidroponik menggunakan media rockwool, cocopeat dan tanah (kontrol). Data yang dikumpulkan terdiri dari beberapa attribut morfologi dari tanaman yang umum digunakan dalam menilai kualitas bibit serta pertumbuhannyaantara lain tinggi tanaman (cm), jumlah daun (cm), panjang akar (cm), dan berat akar (gr). Data yang diperoleh diuji melalui analisis sidik ragam dan kemudian diuji lebih lanjut menggunakan uji Beda Nyata Jujur (BNJ) pada taraf kesalahan 5%. Hasil penelitian menunjukkan bahwa media tanam cocopeat dapat meningkatkan pertumbuhan tinggi dan jumlah daun tomat cherry dalam pembibitan secara hidroponik. Media tanam cocopeat juga meningkatkan bobot akar tomat cherry dan cabe rawit serta panjang akar lima komoditi hortikultura yang diuji dan secara. Media tanam rockwool menghasilkan pertumbuhan tinggi dan jumlah daun yang secara nyata lebih rendah daripada cocopeat dan tanah. Media tanam cocopeat berpotensi untuk dimanfaatkan sebagai media tanam pembibitan tanaman sayuran secara hidroponik.
