Penelitian tentang Pemanfaatan Pupuk Organik Cair (POC) pada Budidaya Tanaman KolBunga Brassica oleraceae var. botrytis L. subvar. cauliflora DC. dilakukan di Tombolo Pao, Kecamatan Tombolo Pao, Kabupaten Gowa Sulawesi Selatan. Analisis kandungan tanah dilakukan di Laboratorium Kimia dan Kesuburan Tanah Jurusan Tanah Fakultas Pertanian Universitas Hasanuddin, Makassar. Penelitian bertujuan untuk mengetahui pengaruh pemanfaatan pupuk organik cair pada budidaya tanaman kol bunga dan dosis yang optimal untuk pertumbuhan dan produksi tanaman kol bunga Brassica oleraceae var. botrytis L. Penelitian ini disusun dalam Rancangan Acak Kelompok dengan 5 perlakuan dan 3 kelompok. Analisis data menggunakan Analysis of variance. Hasil yang berbeda nyata dilanjutkan dengan uji Beda Nyata Terkecil (BNT). Hasil penelitian menunjukkan bahwa pemberian pupuk organik cair dengan dosis 30 ml/l air memberikan pengaruh yang sangat nyata terhadap tinggi tanaman, jumlah daun, berat bunga, berat total tanaman, dan diameter bunga, serta berpengaruh nyata terhadap lebar daun, diameter batang dan panjang akar. Kata Kunci: Kol Bunga Brassica oleraceae var. botrytis L. subvar. cauliflora DC., Pupuk organik cair, budidaya.
Plumbum or lead is a type of heavy metal that is dangerous if it has exceeded the threshold of 0.07 µg/g based on the National Standardization Agency SNI 2004. This type of heavy metal is found in nature such as in soil, water, and air. The purpose of the study was to determine the phytoremediation ability of two types of ornamental plants, namely Celosia argentea L. and Mirabilis jalappa L., against Plumbum (Pb) metal in soil. The growth parameters observed consisted of plant height, plant stem diameter, number of leaves, leaf length, and leaf width. The ICP-MS (Inductively coupled plasma-mass spectrometry) was used to analyze the plumbum (Pb) content in soil and plants. The results ofinitial soil analysis prior to the plant planting process (phytoremediation) were 103.17 µg/g which had exceeded the predetermined threshold. The result of the analysis after phytoremediation of Celosia argentea L. showed plumbum (Pb) content of 49.685 µg/g in soil and 1,9548 µg/g in plants. Similarly, the analysis of Ph content after phytoremediation of Mirabilis jalappa L. was 47.802 µg/g in soil and 5.3077 µg/g in plants. Based on biomass calculation of Celosia argentea L. and Mirabilis jalappa L., the obtained Plumbum (Pb) content was 18.84% and 27.85%, respectively. The percentage of Pb removal of Celosia argentea L. was 51.842%, while Mirabilis jalappa L. was 53.667%. The efficiency of Pb absorption of Celosia argentea L. and Mirabilis jalappa L. was 1.895% and 5.145%, respectively. In conclusion, Ornamental plants Celosia argentea L., and Mirabilis jalappa L., are able to act as phytoremediation agents for Plumbum (Pb) metal that pollutes the soil as evidenced by the decrease in Pb levels in the soil after the phytoremediation process.Keywords: Plumbum (Pb), Phytoremediation, Celosia argentea L., Mirabilis jalappa L.
This research is the phenotypic characteristics and grouping of hybrid waxy corn Zea mays L. product of the top cross had been carried out in the experimental plant Indonesian Cereals Research Institute (ICERI) in Maros South Sulawesi. This research aims to determine the phenotypic characters of the hybrid of waxy corn Zea mays L. product of the top cross and grouping based on its phenotypic characteristics. This research used a randomized block design (RBD) with 17 th treatments (corn strains) and three replications. Waxy corn strains used were: URI 1 (G8), G8G1, G8G2, G8G3, G8G4, G8G5, G8G6, G8G7, Soppeng (G10), G10G1, G10G2, G10G3, G10G4, G10G5, G10G6, G10G7, and Paramitha.. All data (qualitative and quantitative) are arranged in binary tables and grouped using the NTSYST program. The observations show that the data obtained comes from 14 quantitative characters and 17 qualitative characters. Quantitative data from 14 characters were tested and the results of 10 characters were significantly different and the other 4 were not significantly different. The grouping results show that the 17 corn strains studied formed 3 groups at the similarity coefficient of 0.76. Soppeng's corn is different from the others.
Manfaat pengolahan ikan adalah untuk meningkatkan nilai ekonomis serta memperlambat terjadinya proses pembusukan ikan. Melalui diversifikasi pengolahan diharapkan dapat meningkatkan pendapatan masyarakat pesisir sekaligus menjadi solusi pemanfaatan ikan-ikan ekonomis rendah seperti ikan kadalan, ikan layang dan ikan lemuru yang banyak terdapat di pesisir Desa Pengambengan Kabupaten Jembrana, Bali. Tujuan dari pelaksanaan kegiatan pengabdian ini adalah untuk meningkatkan pengetahuan, keterampilan, dan perubahan perilaku masyarakat pesisir dalam mengoptimalkan pemanfaatan ikan lokal ekonomis rendah. Kegiatan ini dilaksanakan melalui tiga pendekatan yaitu pemberian materi diversifikasi olahan, melakukan kegiatan praktik olahan bersama, dan pendampingan kelompok sasaran. Kegiatan diikuti oleh dua kelompok sasaran yaitu Poklahsar Tanjung Cemara dan Poklahsar Tanjung Wangi. Dalam kegiatan ini diberikan pembekalan materi berupa diversifikasi olahan Sambal Ikan, Abon Ikan dan Otak-otak Ikan. Selama kegiatan praktik, kelompok sangat aktif berpartisipasi dan bersemangat untuk mempraktikkannya kembali di rumah. Hasil dari pendampingan yang dilakukan setelah kegiatan pelatihan menunjukkan bahwa kelompok telah melakukan olahan ikan dalam bentuk sambal ikan dan abon ikan dan telah menjadi produk olahan yang dijual sehingga memberikan tambahan penghasilan bagi kelompok.
