ABSTRACTImproving soil quality from sand mining area by application of biological ameliorantsSoil from disturbed mine sites render to be unfertile and have poor characteristics. One of the solutions to improve the soil and to rehabilitate the ecosystem is through application of biological amendments such as organic matter, soil microbes, and plant which known to be adaptive such as dragon fruit (Hylocereus costaricensis). This study was aimed at understanding the effects of arbuscular mycorrhizal (AM) fungi and organic matter on soil C-organic, soil N-total, soil C/N, and length of bud of dragon fruits grown on soil originated from sand mining, Sumedang, Indonesia under greenhouse condition. Different types of organic matter i.e. chicken manure, goat manure, cow manure and rabbit manure were applied. Results of experiment showed that application of manures and AMF was significantly improved soil C-organic content, N-total, and C/N, as well as length of bud of dragon fruit plants. Planting soil from sand mine sites with dragon fruit combined with organic matter and mycorrhiza has potential as restoration tools on ecosystem of sand-mining areas.Keywords: Sand-mine, Mycorrhiza, Manure, Dragon fruitABSTRAKTanah pada lahan bekas tambang galian pasir memiliki tingkat kesuburan yang rendah. Salah satu upaya untuk meningkatkan kualitas tanah dan ekosistem di wilayah penambangan pasir adalah melalui aplikasi amelioran biologis berupa bahan organik, mikroba tanah, dan tanaman yang dikenal adaptif terhadap lahan berpasir, seperti buah naga (Hylocereus costaricensis). Tujuan dari penelitian ini adalah untuk mengetahui efek pemberian berbagai jenis pupuk kandang (PK: berasal dari kotoran ayam, kambing, sapi, dan kelinci) dan fungi mikoriza arbuskula (FMA) terhadap kandungan C-organik, N-total, C/N tanah dan panjang tunas bibit buah naga super merah yang ditanam pada tanah bekas tambang pasir asal Sumedang, Indonesia pada kondisi rumah kaca. Hasil percobaan menunjukkan bahwa pemberikan pupuk kandang dan mikoriza meningkatkan kandungan C-organik, N-total, C/N tanah dan panjang tunas bibit buah naga super merah secara nyata. Kombinasi PK sapi dengan FMA atau PK kelinci tanpa FMA menghasilkan tunas bibit buah naga terbaik. Penanaman buah naga di lahan bekas tambang pasir yang dikombinasikan dengan pupuk kandang dan mikroba tanah seperti fungi mikoriza memiliki potensi sebagai sarana untuk restorasi ekosistem di wilayah penambangan pasir.Kata kunci: Tambang pasir galian C, Pupuk kandang, Mikoriza, Buah naga

Abstract

ABSTRACTContinues phosphate fertilization as well as organic matter amendment can increase cadmium concentrationin soil and induce more cadmium uptake by plants. Pytoremediation using non edible plant such as ramie(Boehmeria nivea L. Goud) is cheap and effective method to extract Cd from Cd-contaminated soil. Since inplant tissue Cd is bound in phytochelatin peptide which contains nitrogen and sulphur, the objective of thisgreen house experiment was to assess the influence of nitrogen fertilizer in form of urea on cadmiumuptake, nitrogen and sulphur concentration in shoots as well as shoot dry weight of 60-day old ramiegrown in cadmium-contaminated soil. The experiment was set up in a Split Plot Design with two treatmentsand three replications. The main plot was cadmium levels (0, 10 and 15 mg kg-1) and subplot was urea level(0, 5.0 and 7.5 g pot-1). The result showed that the increase of cadmium concentration in soil enhanced itsconcentration in ramie shoot regardless of urea levels. However either cadmium or urea did not changesulphur concentration in ramie shoot. Urea of 7,5 g/pot increased shoot dry weight but adding CdCl2.H2O of15 mg/kg did not change shoot dry weight. This experiment demonstrated that ramie was able to grow inrelatively high level of soil cadmium, and higher cadmium uptake by ramie shoot was not followed by anincrease in nitrogen as well as sulphur uptake.Keywords: Cadmium, Urea, Nitrogen, Sulphur, Ramie.

Abstract

Pemanfaatan Fungi Mikoriza Arbuskula (FMA) sebagai pupuk hayati telah diketahui mampu meningkatkan pertumbuhan dan produktivitas tanaman. Penyediaan sumber inokulum FMA sangat berkaitan erat dengan sumber bahan baku pembawa atau media tumbuh inokulum FMA. Penelitian ini bertujuan untuk mengetahui pengaruh komposisi media tumbuh dan jenis FMA yang berbeda terhadap persentase infeksi akar dan pertumbuhan tanaman sorgum. Perlakuan komposisi media tumbuh inokulan  terdiri atas beberpa komposisi zeolit dan arang sekam. Isolat FMA yang digunakan adalah: 1) Glomus sp., 2) Gigaspora sp., dan 3) Glomus sp. + Gigaspora sp. Hasil penelitian menunjukkan bahwa tidak terjadi interaksi antara komposisi media tumbuh (zeolit dan arang sekam) dengan jenis FMA terhadap peningkatan persentase infeksi akar, nisbah pupus akar dan tinggi tanaman sorgum. Secara mandiri perlakuan komposisi media memberikan pengaruh yang nyata terhadap nisbah pupus akar dan tinggi tanaman sorgum. Komposisi media tumbuh terbaik yang menghasilkan persen infeksi akar  tertinggi (62 %) adalah komposisi media 50 % zeolit + 50 % arang sekam, sedangkan nisbah pupus akar tertinggi diperoleh dari komposisi media tumbuh  75 % zeolit + 25 % arang sekam.  Walaupun kontrol (media zeolit 100%) lebih baik di dalam meningkatkan pertumbuhan tanaman sorgum, akan tetapi komposisi 75 % zeolit + 25 % arang sekam memiliki potensi untuk digunakan sebagai media produksi inokulan FMA.  Komposisi media ini dapat digunakan baik bagi produksi inokulan tunggal Glomus sp. atau Gigaspora sp., maupun inokulan campuran Glomus sp. + Gigaspora sp.

Abstract

Enhancement of productivity of potato plants grown on poor-P soil such as Inceptisols due to application of arbuscular mycorrhizal fungi (AMF) has been acknowledged. However, whether this AMF improved the quality of potato tubers is still need further investigation. This study was conducted to evaluate the effectiveness of AMF in enhancing potato quality and determine whether the addition of compost and biochar to soil can support the productivity of this biofertilizer in enhancing the nutrient content in the tubers of potato plant. Screen house experiment was set up in factorial design with treatments were organic matter types (compost and compost plus biochar), and application of arbuscular mycorrhiza (without and with AMF consisted of Glomus sp. and Gigaspora sp.). Results of experiment showed that there was no interaction effect between organic matter and AMF on quality of potato tubers, however, the individual treatment especially AMF  increased the content of protein and lipid of potato tubers. Biochar that added to soil with compost was also increased the lipid content of potato tubers. This finding showed that AMF application in potato production grown in poor P-soil was not only increased the yield of potato, but also increased the quality of potato tubers.

Abstract

Sterilisasi dan komposisi media merupakan faktor penentu dalam menghasilkan inokulan mikoriza yang berkualitas. Penelitian ini bertujuan untuk mendapatkan kualitas inokulan konsorsium FMA dan MHB yang terbaik dengan merekayasa media tanam dan metode sterilisasi. Percobaan telah dilakukan di rumah kaca menggunakan Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri atas dua faktor perlakuan. Faktor pertama adalah sterilisasi media yang terdiri atas: (1) sterilisasi melalui pencucian dengan air, (2) sterilisasi menggunakan autoklaf, (3) sterilisasi dengan NaOCl, dan (4) sterilisasi dengan irradiasi gamma. Faktor kedua adalah komposisi media yang terdiri atas: (1) 100% zeolit, (2) 75% zeolit : 25% arang sekam, dan (3) 50% zeolit : 50% arang sekam. Hasil penelitian menunjukkan bahwa terdapat interaksi antara sterilisasi dan komposisi media terhadap jumlah spora MA, namun tidak berpengaruh terhadap nisbah pupus akar sorgum. Sterilisasi media secara mandiri berpengaruh terhadap populasi MHB. Perlakuan sterilisasi irradiasi gamma + komposisi media 75% zeolit : 25% arang sekam merupakan perlakuan yang cenderung lebih baik dalam meningkatkan jumlah spora MA, populasi MHB, dan nisbah pupus akar sorgum.

Abstract

Quality of biofertilizer such as arbuscular myorrhizal fungi could be improved through the selection of appropriate sterilization and composition of the medium. The objective of the experiment was to determine the effect of sterilization and carrier composition on root colonisation, root length and weight of sorghum root. A green house experiment was conducted in randomized block design. The factors were: 1. methods of sterilization (ie. control; autoclave; NaOCl 10%; Co-60 gamma irradiation), and 2. composition of the carrier of mycorrhiza (100% zeolite; 75% zeolite + 25% rice charcoal;  50% zeolite + 50% rice charcoal). Results showed that there was no interaction effect of sterilization and composition of carrier on root colonisation, root length and weight of sorghum root. However, different technique of sterilisation gave differences on root colonisation, root length and weight of sorghum root. Sterilization using NaOCl 10% was not recommended. Gamma Co-60 irradiation sterilization did not have difference with control and autoclave, however there was  tendency  that irradiation technique gave better results to all parameters measured.

Abstract

Pada tahun 2004 di DAS Cimanuk Hulu telah diperkirakan mempunyai lahan kritis seluas 40.876 ha, namun hingga kini belum diketahui bagaimana penanganan terhadap fenomena tersebut. Sementara itu kejadian cuaca ekstrim di wilayah ini pada tanggal 20 September 2016 yang melahirkan bencana banjir bandang di kota Garut dapat dijadikan sebagai indikator tentang masih belum tertanganinya secara baik lahan kritis yang ada. Untuk itu perlu adanya upaya untuk menangani masalah tersebut, salah satunya dengan upaya deforestasi melalui agroforestri. Metode kegiatan pengabdian kepada masyarakat di Desa Cilampuyang Kecamatan Malangbong  ini berupa sosialisasi, penyuluhan, dan penanaman pohon. Penyuluhan dan diskusi dilaksanakan sebanyak dua kali bertempat di aula BPDASHL Cimanuk desa Cilampuyang. Kegiatan penanaman dilaksanakan setelah acara sosialisasi untuk memberikan ketrampilan secara teknis mengenai sistem agroforestry.
