Abstract

Keberlanjutan sektor agribisnis manggis tidak lepas dengan dukungan dari tata kelola teknis budidaya saat pramusim pohon. Dukungan alih pengetahuan dalam pelaksanaan good agriculture practice (GAP) manggis saat pra musim dan pasca musim panen diperlukan dalam mempertahankan produksi dan kualitas periode pohon manggis berikutnya. Praktek GAP yang dilaksanakan kepada kelompok bina mandiri adalah perawatan pohon manggis dengan menyediakan pupuk kompos dari bahan-bahan yang tersedia di dalam lahan pohon manggis. Tujuan dari kegiatan pengabdian ini adalah pendampingan dalam pembuatan pupuk kompos memanfaatkan sampah lokal di sekitar kebun. Partisipasi mitra kelompok tani Bina Mandiri adalah melakukan praktek dalam pembuatan pupuk kompos. Hasil pelatihan dan pendampingan di kelompok tani Bina Mandiri adalah adanya kemampuan individu dan kelompok untuk memproduksi pupuk kompos secara mandiri. Anggota kelompok lainnya melakukan pembuatan pupuk kompos secara mandiri di setiap lahannya. Hasil kompos setelah 30 hari dipersiapkan untuk suplai nutrisi manggis setelah selesai berbuah.

Abstract

Tujuan penelitian ini adalah mengetahui kondisi (tingkat kerusakan) lahan di Lombok Barat saat ini, khususnya yang berkaitan dengan kemampuan lahan memproduksi biomasa, Penelitian dilakukan dengan menggunakan metode survai. Pekerjaan itu diawali dengan pembuatan peta dasar (skala 1:50.000) menggunakan citra satelit Alos Avnir-2, sebagai peta sementara; kemudian dioverlay dengan peta topografi dan landuse. Selanjutnya, dilakukan penentuan titik sample (sampling site), pengecekan kondisi lahan riil kelapang, dan pengambilan  sample. Peta dasar dikoreksi berdasarkan hasil pengamatan lapang, dan selanjutnya dibuat peta sebaran lahan berdasarkan tingkat produktivitasnya sebagai penghasil biomassa. Hasil penelitian menunjukkan bahwa luas penghasil biomassa, selain kawasan hutan konservasi, pemukiman, dan tubuh air di Kabupaten Lombok Barat adalah 96,050.43 ha atau 91.13 % dari luas wilayah secara keseluruhan 105392.00 Ha. Secara keseluruhan, tingkat kerusakan lahan berdasarkan produksi biomassa di Kab. Lombok Barat  yang tergolong sangat baik dan baik (produktif) sebagai penghasil biomasa adalah 57,236 ha (54 %), tingkat kerusakan lahan yang tergolong sedang dan buruk adalah 47,594 ha (45 %), dan tingkat kerusakan lahan yang tergolong sangat buruk (tidak produktif sebagai penghasil biomasa) hanya seluas 561.21 ha (±1 %).  Persentase tutupan lahan oleh vegetasi dan kemiringan lereng merupakan faktor pembatas umum kekritisan lahan di kawasan lindung/hutan; sedangkan pada lahan usahatani, faktor pembatas utama berkaitan dengan keterbatasan sumberdaya air untuk usahatani.Kata Kunci : Kerusakan Lahan, Biomassa

Abstract

TA descriptive research aimed to identify the characteristics and name of main soils in Lombok Island was carried out through field observation for soil profiles and landform and laboratory analyses for soil physical and chemical properties. The type or name of soil was defined by using The National (Indonesian) Soil Classification System (2014), Soil Taxonomy (SSS-USDA, 2014), and World Soil Reference (FAO, 2014). There were 4 main types of soil in Lombok Island, which were Litosol, Aluvial, Kambisol, and Vertisol; and a fairly developed soil in limited spots was Mediteran. Based on the soil taxonomy system, those soils were respectively equivalent to Orthents, Fluvents, Undepts, Underts, and Udalfs; whereas based on the soil system of FAO, were Leptisols, Fluvisols, Cambisols, Vertisols, and Luvisols. The main characteristics of Litosol/Orthents/Leptosols Lombok were shallow solum (< 25 cm on the rocks or lithic contacts), coarse textured (sandy), nutritionally deficient, very low CEC (< 5 cmolc.kg-) and C-organic content (< 1 %). Aluvial or Fluvents, were mainly utilized as paddy soil, consisting of several layers which it clay and C-organic content were changed irregularly with depth, CEC of top soil (Ap) was medium (5–10 cmolc.kg-), and it was relatively fertile. Kambisols or Undepts was fairly deep (consisting of 40 – 60 cm of A and B horizons,), loamy textured, fairly fertile, CEC was medium, and C-organic content was low – medium (1–2 %). Vertisol or Uderts was characterized by a significant swell-shrinking properties, clay textured, extremely hard to be cultivated, high CEC, Ca, and Mg, and relatively fertile soil. Mediteran or Udalf was a further developed soil (solum > 100 cm), clay translocation has been occurred from upper (E) to lower horizons (Bt), CEC was fair, and it was relatively fertile soil. In conclusion, the pedologic development of soils in Lombok Island was relatively slow due mainly to the low–moderate rainfall, and the soil types were dominated by Litosols, Aluvials, Kambisols, and Vertisols, and Mediteran in small area. In order to provide a complete reference for the characteristics of main soils in Lombok Island, it necessaries to define mineralogy composition through X-ray diffraction analysis (XRD) and thermogravimetry analysis (TGA) of the clay fractions of the soils

Abstract

test of modifying the properties of vertic material by using a ball milling technique was carried out with the primary aim to eliminate the vertic (swelling-shrinking) property and increase the electrical charge of the material. The clay fraction of Vertisol was dried and ball milled for 5, 10, and 20 minutes. Results reveal that the clay fraction of the soil material was dominated by montmorillonite mineral, and ball milling for > 5 minutes transformed the crystalline montmorillonite into amorphous (non-crystalline) particles. Those changes were followed by increasing the vertic features, cation exchange capacity, water holding capacity, and suspension effect of the milled material. The improvement of vertic characteristics might be due to the increase of electric charge of the milled particles. Thus, high-energy ball milling was an effective technique to improve the reactivity and vertic property of vertic material of Vertisols. Further studies are needed to evaluate the potential uses of modified vertic materials as ceramic material, cement component, adsorbent of heavy metals, and other contaminants, or catalysator

Abstract

Silicate rocks, the abundant plant nutrient source in Indonesia, have not been evaluated for use as a fertilizer/and soil ameliorant. This research was aimed to identify (1) mineral and elemental compositions of silicate rocks originated from Galunggung, Kelud, Tambora, and Rinjani Volcanoes and (2) soil properties determining dissolution rate of plant nutrients from the silicate rock fertilizers (SRFs). The rocks were ground with a ball mill for 10 min providing SRFs with medians of particle size of 30 – 50 mm. Each SRF was added to 6 soils from West Java, East Java, and Lombok Island at a rate equivalent to 20 t ha-1, incubated for 28 days in a laboratory condition.  Results indicate that adding SRFs clearly increased soil pH with negligible effect on soil salinity. Adding SRFs also increased quantity of citric-oxalic-extractable plant nutrients (Ca, K, Zn, and Cu) and activity of soil micro-organisms. Dissolution of plant nutrients from the SRFs in the soils was mainly determined by combination factors of C-organic content and pH of soils before application of the SRFs. It was concluded that SRFs originated from those volcanoes may be used as a plant-multi nutrient source and a remedial agent for acidic and biologically degraded soils. However, the true effectiveness of SRFs for those uses needs to be further tested under various soil-plant systems.

Abstract

A laboratory study was conducted to identify the effects of milling under various conditions, including use of water and potassium as milling lubricants, on several physicochemical properties of rock phosphate fertilizer. The identified properties were the XRD patterns, particle size distribution, surface area, and NaHCO3-extractable P of the fertilizer. Milling for 2 hourssignificantly reduced particle size, promoted amorphization,increased surface area and amount of extractable P in 1N NaHCO3 of rock phosphate fertilizer, with those effects for dry milling were much greater than for wet milling. Wet milling and use of additives (KCl and K-feldspar) minimized the occurrence of agglomeration during milling process. Although further tests in soil-plant system are required, dry milling may be recommended as a simple method for manufacturing an agronomically effective P + K fertilizer.

Abstract

ABSTRAK Penelitian ini bertujuan untuk melihat efektifitas pemberian pupuk batuan silikat berpestisida nabati (Biopestisida fertilizer) terhadap intensitas beberapa penyakit pada tanaman jagung (Zea mays L.). Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) dengan 2 faktor yakni konsentrasi NP dan frekuensi BF (Biopestisida fertilizer) yang ditata secara faktorial dan diulang 3 kali sehingga diperoleh 18 unit percobaan. Hasilnya ditemukan tiga jenis patogen dari golongan cendawan yang menginfeksi tanaman jagung, yakni penyakit bercak/ hawar daun oleh Helminthosporium sp., penyakit busuk batang oleh Pythium sp. dan penyakit busuk tongkol oleh Fusarium sp. Namun, intensitas serangan ketiganya tergolong ringan. Aplikasi biopestisida fertilizer memberi pengaruh nyata terhadap intensitas penyakit busuk tongkol dan busuk batang, sedangkan NP tidak memberi pengaruh nyata, dan interaksi pupuk NP dan BF juga tidak memberi pengaruh nyata terhadap intensitas penyakit. Pada penyemprotan BF 2 kali (BF2) terlihat adanya kenaikan hasil gelondongan dan pipil kering, akan tetapi pada penyemprotan BF 4 kali (BF4) justru terlihat mengalami penurunan. Dengan demikian, aplikasi BF optimal adalah pada 2 sampai 3 kali penyemprotan. Untuk penelitian selanjutnya, produk ini perlu diuji pada varietas jagung yang lain atau pada komoditi yang berbeda terhadap keberadaan jenis penyakit yang lain. ABSTRACT The aim of this study is to explore the effectiveness of application of silicate phytopesticidal fertilizer on the intensity of some diseases in maize (zea mays l). The method used in this research was factorial randomized completely block design with two factors (concentration of np and the frequency of phytopesticidal fertilizer). each treatment has three replications. the result indicated that there are three kinds of fungi pathogens infected maize such as blight (Helminthosporium sp), stem rot (phytium sp) and cob rot (Fusarium sp). however, the intensity of the three pathogens was moderate. the application of silicate phytopesticidal fertilizer had significant effect to the intensity of cob rot and stem rot, whereas, the np concentration and the interaction between np fertilizer and silicate phytopesticidal fertilizer had not significant effects to the intensity of the diseases. on the twice spraying of phytopesticidal fertilizer (bf2) indicated the increment of yield of dry shells. however, on the four times spraying of phytopesticidal fertilizer (bf4) indicated the reduction. thereby, the application of phytopesticidal fertilizer has optimum effect on 2 to 3 times of spraying. for the following study, this product needs to be tested on other varieties of maize or other commodities to the existence of other diseases.
