The area of agricultural land, especially paddy fields, is related to the level of rice production. Conversion of agricultural land to non-agriculture will have an impact on the availability of rice supply. This study aims to identify changes in paddy field land use in 2005 - 2016 using high-resolution satellite imagery and calculate the need for rice per capita in Pallangga District. This research utilizes the application of geographic information systems in monitoring changes in paddy field use. The method used in the classification of land use is digitizing on screen. The conversion of paddy fields to non-paddy fields was obtained from the results of overlapping maps of Pallangga District land use maps in 2005 and 2016 and presented in the form of cross tabulations. The accuracy test results obtained the overall accuracy value of 98.04%, and the kappa accuracy value of 0.98. This study shows that paddy field area has decreased by 305.25 ha. The change consisted of 17.68 ha into a water body, turned into a garden of 132.86 ha and became a settlement of 154.71 ha. The conversion of paddy fields in Pallangga District in 2005-2016 affected rice production. The results of the analysis of the needs of rice per capita per year show that in 2017 Pallangga District is surplus in the supply of rice to its population. However, based on population projection, the decrease in land area and rice production in Pallangga Subdistrict in 2020 was unable to meet the rice needs of its population of 1,027 tons

Ultisol soil has high potential for the development of dryland agriculture. However, this soil use faces obstacles because the nutrient content in Ultisol soils is generally low. This study aims to determine the effect of manure and straw compost on increasing nutrient content of phosphorus in ultisol soil. This study used a completely randomized design (CRD) with 9 levels of treatment, namely P0 = control, P1 = manure 10 tons / ha, P2 = manure 5 tons / ha, P3 = compost 5 tons / ha, P4 = compost 10 ton / ha, P5 = manure 5 tons / ha + compost 10 tons / ha, P6 = manure 10 tons / ha + compost 5 tons / ha, P7 = pellet compost 5 tons / ha, P8 = compost pellets of 10 tons / ha. The treatment was repeated 3 times. The results showed that giving 10 tons / ha of manure plus 5 tons / ha of compost had a significant effect on reducing Al-dd content, and increasing P-available, pH, base saturation, cation exchange capacity and C-organicon Ultisol soil. Giving pellet fertilizer 10 tons / ha gives a real influence on the growth of maize plants.

Bawang merah salah satu komoditas sayuran penting yang banyak dibutuhkan masyarakat sebagai bumbu penyedap masakan. Kebutuhan dari tahun ke tahun mengalami peningkatan seiring dengan bertambahnya jumlah penduduk dan beragamnya produk olahan. Ketersediaannya yang langka menimbulkan keresahan di tengah masyarakat dan mempengaruhi inflasi secara nasional. Sebagai komoditas penting maka pemerintah mencanangkan produksi nasional bawang merah sebesar 1.410.847 ton. Untuk mencapai produksi tersebut dibutuhkan benih sebanyak 155.556 ton umbi bibit dan biji bibit (True shallot seed) sebanyak 28.590. Selama ini, biaya usahatani bawang merah khususnya dari bibit dapat mencapai 60% dari total biaya produksi dengan mutu bibit yang kurang memenuhi syarat agronomi. Karena bibit diperoleh dari umbi yang diseleksi dari hasil panen umbi untuk konsumsi. Semestinya produksi untuk bibit berbeda cara pe-nanganannya dengan produksi untuk konsumsi. Perbanyakan tanaman bawang merah dengan umbi memiliki kekurangan di antraanya biayanya mahal karena dibutuhkan bibit dalam jumlah besar (1,0-1,5 ton/ha), mudah rusak dan umur simpannya singkat (kurang 3 bulan) serta mengalami masa dormansi. Sedangkan keuntungan menggunakan biji adalah biaya produksinya rendah karena dibutuhkan 5-6 kg/ha, hemat biaya transportasi bibit, umur simpan lebih lama (2 tahun), ukuran umbi lebih besar, dan produksinya lebih tinggi. Penggunaan biji untuk bibit bawang merah merupakan alternatif dalam membudidayakan bawang merah lebih murah dengan produktivitas yang tinggi. Kata Kunci, Bawang merah, biji untuk bibit, dan umbi untuk bibit.

Reclamation of post-nickel mining soil requires a long process and renewable innovations to improve soil properties. One of the alternative technologies for post-mining soil reclamation is utilizing oil palm empty fruit bunches (OEFB) as biochar and applying calcite (CaCO3). The objective of this research was to determine the effect of OEFB and the application of CaCO3 on the properties of post- nickel mining soil and the growth of Mucuna sp. This research was a pot experiment using a factorial randomized block design method. Treatments tested were combinations of three OEFB biochar (B) levels, i.e., B1 = 2.5%, B2 = 5%, and B3 = 7.5% of soil weight, and three calcite (K) dosages, i.e., K1 = 1.5, K2 = 3, K3 = 4.5 t ha-1. The soil parameters measured included soil pH, available P, organic C, cation exchange capacity, and exchangeable Al, Ca, Mg, K, and Na. The parameters of Mucuna sp. measured were plant height and plant dry weight. The results showed that applying biochar and calcite to post nickel mining soil significantly increased soil pH, available P, organic C, cation exchange capacity, growth of Mucuna sp. and decreased exchangeable Al content. Treatment of biochar 7.5% by weight of soil and 4.5 t calcite ha-1 gave the best effect on improving soil fertility and growth of Mucuna sp. compared to other treatments.
