Abstract

The research was conducted at the Experimental Garden of the Faculty of Agriculture, Baturaja University. Ogan Komring Olu Regency. The materials used were: Dendrobium sp orchid seedlings, charcoal, ferns, coconut fiber. The tools used were plastic/paranet, 7 cm diameter plastic pots. ruler, pot rack, treatment labels, stationery, and cameras. The study used a Randomized Block Design (RAK). The factorial treatment consisted of a combination of Shade (N), and planting media composition (M), the combination of Shade (N) consisted of 3 levels and the composition of the planting media consisted of 3 levels, the treatment was repeated three times so there were 27 combinations. Each treatment consisted of 5 plants with five sample plants. The variables observed were the percentage of growth, plant height, number of leaves, number of roots, root length, and wet weight of the plant. From the results, it was obtained that the average vegetative appearance of dendrobium orchid seedlings from the shade and planting media treatments showed more vigorous growth than without shade. The average growth of shaded seedlings was higher than without shade. Growth was higher in 50% shade. The average growth of orchid seedlings was higher in coconut fiber, fern, and rice husk charcoal (1:1:1) planting media except for leaf chlorophyll content. Correlation regression testing of the percentage of survival determined plant height by 0.55. number of leaves 0.19, dry plant weight 0.57, root length 0.005, number of roots 0.63, and leaf chlorophyll content 0.41. Based on the coefficient of determination (R2), the percentage of plant growth correlated with the number of roots, dry plant weight and plant height. The conclusion of this study is based on the plant growth pattern, the use of 50% shade and the use of coconut fiber, fern, and rice husk charcoal (1:1:1) planting media is a better treatment for the growth of Dendrobium sp. Orchids. The percentage of survival determined plant height by 0.55. number of leaves 0.19, dry plant weight 0.57, root length 0.005, number of roots 0.63, and leaf chlorophyll content 0.41. From the results of the determination coefficient (R2), it can be seen that the percentage of plant growth is correlated with the number of roots, dry weight of the plant and plant height.

Abstract

The objective of this research was to study and cluster of Jatropha germplasm belonging to University of Sriwijaya. This research was conducted from September 2007 until July 2008. The research used 14 accessions of Jatropha taken from some regions in Indonesia, namely: Komering, Palembang, Yogyakarta, Indralaya, ATP2, Pontianak, Lahat, Pagaralam, Curup, Lampung, Medan Aceh Besar, Pidi and Gorontalo. Accessions of Jatropha curcas L. were planted at Agro Techno Park (ATP) Bakung village, Indralaya Utara district Ogan Ilir, South Sumatera using Randomized Complete Block Design. RAPD analysis using 20 primers was done at RGCI (Research Group on Crop Improvement), Bogor Agricultural University. Dendrogram based on RAPD analysis produced five groups that were: the first group was Komering, Lahat, Pidi, Indralaya, Aceh Besar, Pontianak and Curup. The second group was Palembang and ATP2. The third group was Pagaralam, Gorontalo, and Medan. Lampung was included in to fourth group. The fifth group was Yogyakarta. Dendrogram from morphological marker had also five groups. First group was: Komering, Indralaya, Pontianak. Lahat, and Pagaralam. Second group was: Palembang, Lampung, Pidi, Medan, and ATP2. Third group was: Curup. Fourth group was: Yogyakarta and Gorontalo. Fifth group was: Aceh Besar. The difference of member from each groups between dendrogram using RAPD and morphological markers indicated that the bands resulted from RAPD did not have relation with characters observed. Key words: Jatropha curcas L, RAPD analysis, Morphologycal marker, cluster analysis

Abstract

Tantangan utama dalam budidaya porang adalah meningkatkan kemampuan adaptasi tanaman terhadap naungan, sehingga porang dapat tumbuh dengan baik di bawah kanopi pohon perkebunan. Percobaan ini bertujuan untuk mengkaji pertumbuhan siklus hidup pertama tanaman porang yang berasal dari ukuran bulbil yang berbeda pada tanaman sela di antara pohon karet. Percobaan ini dilaksanakan di kebun karet rakyat yang telah berumur 20 tahun, pada bulan Agustus 2021 - Januari 2022, di Desa Lubuk Batang Kabupaten Ogan Komering Ulu Provinsi Sumatera Selatan. Penelitian ini menggunakan Rancangan Spilt-Split Plot dengan 3 faktor. Petak utama terdiri atas perlakuan naungan yaitu tanpa naungan (N0) dan ditanam di antara pohon karet (N1), dan anak petak  yang terdiri dari perlakuan berat bulbil yaitu bulbil  2 g - 3,9 g (B1), bulbil 4 g - 5,9 g (B2), dan bulbil 10 g -15,9 g (B3); anak-anak petak terdiri atas  morfologi bulbil yaitu tanpa turberkel (D0) dan tuberkel menonjol (D1). Hasil percobaan menunjukkan porang yang ditanam di antara tanaman karet lebih cepat muncul tunas dan mempercepat pecah selubung pertiole 33 HST dan 43,94 HST. Selain itu, tuberkel yang menonjol juga mempersingkat waktu kemunculan tunas selama 45,52 hari. Selanjutnya berat bulbil yang lebih tinggi yakni 10 g – 15,9 g  juga memengaruhi morfologi tanaman porang di antara panjang midrib 14,17 cm, lebar anak daun 5,61 cm,  serta luas daun 212,81 cm. Naungan menjaga kelembapan substrat namun sedikit memperlambat kemunculan tunas dan membuat tunas lebih pendek, namun memperpanjang tangkai daun, meningkatkan luas daun, serta mengurangi ketebalan daun. Selain itu, semakin besar bobot bulbil, semakin cepat pertumbuhan tunas dan tanaman porang. Kondisi bulbil dengan tuberkel menonjol mempercepat kemunculan tunas di atas permukaan tanah dibandingkan dengan bulbil yang masih dalam kondisi tanpa turberkel.

Abstract

This Community Service (PkM) activity was carried out in Tanjung Sari Village, Pengandonan District, Ogan Komering Ulu Regency (OKU), to improve the knowledge and skills of farmers/breeders in utilizing goat urine waste as raw material for liquid organic fertilizer (POC). The main problem of the community is the dependence on chemical fertilizers and the lack of optimal use of livestock waste that has the potential to pollute the environment. The implementation method is carried out through counseling, training, and demonstrations of making POC using local ingredients (goat urine, ginger-turmeric-galangal rhizomes, EM4, dolomite, shrimp paste, and molasses). POC is fermented for two weeks and applied to corn and vegetable crops at a dose of 200 ml/L of water. Field observations showed that plants that were given POC had greener leaves, stronger stems, and more uniform growth compared to controls without POC. This activity improves farmers' practical skills in producing organic fertilizers independently and encourages productive livestock waste management. Thus, this PkM contributes to increasing crop productivity and strengthening sustainable agricultural practices in Tanjung Sari Village.ABSTRAKKegiatan Pengabdian kepada Masyarakat (PkM) ini dilaksanakan di Desa Tanjung Sari, Kecamatan Pengandonan, Kabupaten Ogan Komering Ulu (OKU), untuk meningkatkan pengetahuan dan keterampilan petani/peternak dalam memanfaatkan limbah urine kambing sebagai bahan baku pupuk organik cair (POC). Permasalahan utama masyarakat adalah ketergantungan pada pupuk kimia dan belum optimalnya pemanfaatan limbah ternak yang berpotensi mencemari lingkungan. Metode pelaksanaan dilakukan melalui penyuluhan, pelatihan, dan demonstrasi pembuatan POC menggunakan bahan lokal (urine kambing, rimpang jahe-kunyit-lengkuas, EM4, dolomit, terasi, dan molase). POC difermentasi selama dua minggu dan diaplikasikan pada tanaman jagung dan sayuran dengan dosis 200 ml/L air. Hasil pengamatan lapangan menunjukkan tanaman yang diberi POC memiliki daun lebih hijau, batang lebih kuat, serta pertumbuhan lebih seragam dibandingkan kontrol tanpa POC. Kegiatan ini meningkatkan keterampilan praktis petani dalam memproduksi pupuk organik secara mandiri serta mendorong pengelolaan limbah ternak yang produktif. Dengan demikian, PkM ini berkontribusi pada peningkatan produktivitas tanaman dan penguatan praktik pertanian berkelanjutan di Desa Tanjung Sari.
