Abstract

This research is a descriptive exploratory study aiming at analyzing the abundance index and diversity index of soil macrofauna in organic and conventional vegetable fields.  The research method used is an entrapment (Pitfall traps) method where traps are installed in a land with 10mx25m of size and results in 10 plots. Each plot has 5 points determined diagonally to place the pitfall traps; therefore, the total sample points are 50 samples per observation location. Identification of macrofauna trapped in the pitfall trap uses a microscope. Based on the results of diversity analysis, soil macrofauna in organic fields has H'2.6546 with an abundance of 2242 individuals, whereas the conventional fields have H'1.6775 with an abundance of 1507 individuals. In terms of dominance index, the conventional fields have a higher evenness of 0225 with a low value of 0229, while the organic fields have a low dominance index of 0077 yet a higher evenness value of 0344. It can be concluded that the diversity of soil macrofauna in the organic vegetable fields in Ternate city has a higher diversity value because the fields have abundant and more even availability of soil macrofauna so that there are no dominant species found. On the other hand, the conventional vegetable fields have low abundance so that the diversity of soil macrofauna in the fields is low due to one dominant species. The results of the analysis in the two fields indicate that the similarity index is 0.803, which means that the similarity value of the macrofauna species in the two fields is close to the index value. An index value is 0 if there are no similar species in both fields and the value is 1 when both fields have the same species composition. However, the diversity of soil macrofauna in the two different fields has an abundance of soil macrofauna so that it can increase soil fertility and maintain the stability of soil macrofauna and its function in a sustainable agricultural system.

Abstract

Meningkatnya permintaan masyarakat akan sayuran mendorong petani untuk meningkatkan produksinya. Upaya yang dapat dilakukan untuk meningkatkan hasil panen antara lain penggunaan pupuk. Pemupukan dengan pupuk kimia merupakan alternatif yang sering dilakukan, namun kelangkaan pupuk kimia di pasaran membuat pupuk tersebut semakin mahal, sehingga perlu dicari alternatifnya. Pembuatan pupuk organik dari limbah tanaman merupakan salah satu alternatif yang memungkinkan, dengan teknologi EM yang akan mempercepat proses produksi pupuk. Kegiatan pengabdian ini dilaksanakan di Kelurahan Kalumata Kota Ternate Selatan dengan tujuan membantu petani mengelola limbah pertaniannya dengan memanfaatkannya sebagai pupuk organik. Peserta pengabdian adalah anggota Kelompok Petani Sayur "Masure". Metode yang digunakan adalah metode penyuluhan dan demonstrasi. Kegiatan dilakukan secara langsung dengan anggota kelompok tani, diawal dan diakhir kegiatan dilakukan penilaian untuk mengetahui tingkat pengetahuan peserta pengabdian. Hasil evaluasi menunjukkan bahwa pengetahuan dan pemahaman anggota kelompok tani “Masure” mengalami peningkatan. Hal ini tercermin dari peningkatan nilai tes akhir, dimana sebagian besar anggota mendapat nilai di atas 80. Peserta dalam kegiatan ini juga dapat memproduksi pupuk organik sendiri dengan memanfaatkan limbah organik dari sisa tanaman pasca panen dan kulit buah.

Abstract

Land use planning is the process of inventorying and assessing the status, potential and limitations of a given area and its resources, which local people interact with or with people who care about the area to determine their needs, wants and aspirations. for the time. Kulaba sub-district is a small part of Ternate City which is located in West Ternate sub-district, which has a characteristic sloping to steep topographic area. The purpose of this study is to plan land use based on land capability, which is in the Kulaba Village, so that it becomes information in farming and other businesses. Determination of sampling points using a map then carried out a land survey with a free survey observation distance system, the approach used is analytic. Classification of land capability is categorized based on the characteristics that are potential and obstacles in its use. This analysis uses the LCLP (Land Classification and Landuse Planning) application. The results showed land use planning based on land capability that the land at the research location in Kulaba Village had four land capability classes namely III, IV, VI and VIII with the limiting factor of surface slope (L), soil permeability (P) and erosion sensitivity (KE). and subsoil texture with an area of 259.4 Ha. The alternative is that C-organic must have an important role in determining the soil's ability to support plants.

Abstract

Signs of soil that has undergone advanced development include clearer horizons, higher fine fraction and lower coarse fraction, brighter soil color, higher levels of free Al and Fe. Soil aggregation is increasing, to a certain extent organic matter and nutrient levels are increasing as well as CaCO levels, and soluble salts. Soil development is characterized by the occurrence of horizon differentiation as a representative of the process of change in the earth's skin both physically, chemically and biologically by reactions in the soil profile there is an addition of organic and mineral materials in the form of solid, liquid or gaseous materials, the disappearance of materials above the soil, the transfer of materials from one part to another in the soil body, the transfer of the form of mineral compounds and organic matter in the soil body This research was carried out in the village of Bobaneigo Madihutu, South Jailolo District, West Halmahera Regency from June to July 2023. The method used in data collection is a free survey method, which is an observation made directly in the field by determining the research location based on land use maps, and administrative maps. The variables observed were C-Organic, N-Total, C/N Ratio, CEC, KB which are soil chemical properties. The results showed that the study of the level of soil development in several types of land use has not experienced weathering or advanced development due to the low content of nutrients.

Abstract

Kompleksitas proses pedogenesis pada pulau vulkanik kecil yang berpengaruh terhadap tingkat perkembangan tanah, khususnya ordo Entisol dan Inceptisol di Kelurahan Moti Kota, Kota Ternate. Kondisi iklim tropis basah, bahan induk piroklastik Kuarter–Holosen, serta variability topografi memunculkan perbedaan morfologi dan sifat fisik-kimia tanah yang signifikan. Tujuan penelitian adalah mengidentifikasi dan membandingkan variasi tingkat perkembangan profil tanah berdasarkan indikator pedogenik termasuk nisbah debu/liat, KTK/liat, rasio C/N, dan rasio Fe-oksalat/Fe-dithionit serta mendeskripsikan karakteristik morfologi, fisik, dan kimia tanah pada dua profil representatif, yakni Entisol (profil II) dan Inceptisol (profil I). Metode yang digunakan meliputi survei toposekuens dengan penggalian profil pada setiap posisi elevasi, deskripsi morfologi lapangan sesuai prosedur USDA, analisis tekstur (metode pipet), pH H₂O, kapasitas tukar kation (NH₄OAc pH 7,0), Saturasi Basa, karbon organik (Walkley–Black), total N (Kjeldahl), serta ekstraksi besi oksalat dan dithionit. Data kuantitatif dianalisis untuk menghitung nisbah indikator pedogenesis dan diklasifikasikan menurut Soil Taxonomy USDA. Hasil penelitian menunjukkan bahwa profil I (Inceptisol) membentuk horizon cambic dengan struktur gumpal menyudut, peningkatan fraksi liat dari 20 % hingga 35 %, nilai KTK 19,95–23,25 cmol(+)/kg, dan decreas­ing basa saturation dari 60 % ke 33 %. Indikator nisbah debu/liat menurun dari 1,25 pada horizon Ap ke 0,15 pada horizon Bb/C, sedangkan rasio Feₒ/Fe_d berfluktuasi menandakan proses transformasi oksida besi lanjutan. Sebaliknya, profil II (Entisol) hanya memiliki horizon A dengan tekstur lempung berpasir, KTK 20,95 cmol(+)/kg, saturasi basa 62 %, nisbah debu/liat 0,85, dan rasio Feₒ/Fe_d 1,10, menggambarkan tanah muda dengan sedikit perkembangan horizon. Kesimpulan penelitian menyatakan bahwa interaksi bahan induk vulkanik, iklim lembap tropis, organisme, topografi, dan waktu menghasilkan gradiens perkembangan tanah dari Entisol ke Inceptisol di Kelurahan Moti Kota. Pemahaman mendalam terhadap variasi ini penting untuk perencanaan penggunaan lahan berkelanjutan, di mana Inceptisol cocok untuk hortikultura intensif dan Entisol memerlukan tutupan vegetatif untuk mencegah erosi.
