Pemanfaatan Pupuk Hayati terhadap Pertumbuhan, Hasil Padi dan Sifat Kimia Tanah pada Lahan Sawah Irigasi

Industrial waste, both in liquid and solid form, often causes environmental pollution, either in the form of an unpleasant odor or a dark color. One of the industrial waste that makes alcohol is processed and added with multi-strain microbes to become Biological Fertilizer (Ciunik). The purpose of this study was to study the use of Ciunik's biological fertilizers on the growth and yield of irrigated rice fields, to obtain information about the effect of Ciunik fertilizer on the chemical properties of rice fields. The research was carried out on irrigated rice fields in Batang Experimental Garden (KP) Batang Regency from March to August 2016. Randomized block design (RAK) with 4 repetitions of 6 fertilization treatments consisting of fertilization according to farmer/comparison (P0), NPK fertilization based on tools Rice Field Soil Test / PUTS (P1), Fertilization Recommendation from the Ministry of Agriculture no. 44 of 2007 (P2), Fertilization 25% Recommendation PUTS + Ciunik (P3), Fertilization 50% Recommendation PUTS + Ciunik (P4), Fertilization 75% Recommendation PUTS + Ciunik (P5). Analysis of growth and yield data used analysis of variance. If there were differences between treatments, it was continued with Duncan's Difference Test (UBD), 05. Soil microbial population data was carried out by descriptive analysis. The results showed that the application of Ciunik biological fertilizer 3 times per application, namely 5 lt / ha (at 0-3 Hbt, 15 Hst, and 25-30 Hst) combined with 75% of the NPK recommended by PUTS (P5) increased. Rice yields were 26.9% (7,450 t Gkg / ha) above control (5,219 t Gkg / ha), but not different from rice yields that applied the recommended fertilizer PUTS (P1) and MOA No. 40 th 2007 (P2). The application of Ciunik's liquid biological fertilizer to rice plants did not affect some of the chemical properties of the paddy soil. &nbsp

TINJAUAN YURIDIS TERHADAP PEMANFAATAN TANAH ASET MILIK PT KAI OLEH PIHAK KETIGA DI KAB. MOJOKERTO BERDASARKAN PERATURAN DASAR POKOK-POKOK AGRARIA

Dalam rangka memberikan jaminan kepastian hukum atas status dan hak kepemilikan tanah, Indonesia telah mengatur secara yuridis aspek kepemilikan tanah melalui Undang-Undang Nomor 5 Tahun 1960 tentang Peraturan Dasar Pokok-Pokok Agraria. Meskipun demikian, konflik penguasaan tanah masih kerapkali terjadi. Di antara sekian banyak pihak yang terlibat dalam konflik penguasaan tanah, PT Kereta Api Indonesia merupakan salah satu pihak yang paling sering terlibat dalam sengketa penguasaan tanah, mengingat perusahaan ini memiliki aset kepemilikan berupa tanah yang dimanfaatkan sebagai jalur transportasi kereta api dan menunjang pekerjaan utamanya sebagai penyelenggara transportasi kereta api di Indonesia. Dalam beberapa kasus, khususnya yang terdapat sangkut pautnya dengan tanah-tanah yang berada di tanah aset milik PT Kereta Api Indonesia, secara yuridis PT KAI masih memegang status kepemilikan atas tanah-tanah tersebut. Namun untuk memberikan nilai ekonomi dan nilai manfaat yang lebih banyak, beberapa masyarakat memanfaatkan tanah tersebut sebagai tempat tinggal, tempat aktivitas perekonomian, dan tempat-tempat kegiatan kemasyarakatan. Hal ini terjadi salah satunya di Kabupaten Mojokerto tepatnya di Kec. Gedeg yang masuk ke dalam DAOP VIII Surabaya. Untuk membahas aspek hukum dari permasalahan tersebut, peneliti membagi fokus ke dalam dua poin, yakni mekanisme penguasaan yang dilakukan oleh masyarakat selaku pihak ketiga dan status hukum yang ada. Penelitian ini menggunakan metode yuridis normatif sebagai metode penelitian. Hasil dari penelitian ini menunjukkan bahwa penguasaan tanah PT KAI oleh masyarakat bertentangan dengan undang-undang yang berlaku sehingga batal demi hukum (dianggap tidak pernah ada)

PENGUASAAN HAK ATAS TANAH OLEH WARGA NEGARA ASING BERLANDASKAN PERJANJIAN PINJAM NAMA

In a country, land is regarded as an integral part of human life. Land becomes one of the essential things needed to sustain their livelihoods as humans require housing or a place to reside. As time goes by and their living needs evolve, humans not only utilize land as a place to live but also see it as an investment due to its high economic value. This situation leads to an increasing land price each year as more individuals require it. Such land-related investments attract foreign nationals to visit or settle in Indonesia for a certain period to balance their investments in the country. To facilitate this, the government establishes legal provisions for foreign nationals with connections to land in Indonesia through various regulations, particularly the Agrarian Law as the legal framework. In reality, many buying and selling activities are conducted through a borrowing agreement between Indonesian citizens and foreign nationals. Therefore, the purpose of this article is to discuss the rights over land in Indonesia for foreign nationals. According to the Agrarian Law, foreign nationals can possess land in Indonesia through the rights of use and leasehold for buildings. However, in practice, ownership rights (Hak Milik) are also highly coveted by many foreign nationals. Therefore, to fulfill their desires, various covert practices are carried out by foreign nationals through legal circumvention, such as borrowing agreements or nominees with Indonesian citizens

Pengggunaan tanaman penutup tanah jenis legum sebagai penyuplai unsur hara dan baran pembenah tanah di hutan tanaman industri

The effect of legume cover crop on soil characteristic was studied to evaluate the possibility of legume cover crop (LCC) as soil amelioration for the next generation of Gmelina arborea Roxb. plantation forest. Three species of LCC: Crotalaria anagyroides (CA), Mucuna chochuchinensis (MC) and Calopogoniurn caeruleum (CC) were planted at the former field of G arborea plantation forest with I plot for control. Above and belowground biomass were studied 4 months after planting (MAP), and soils were sampled 6 months after planting for laboratory analysis. CA is not a creeping plant and has a good suitability to grow well and fast to flower. The growth rate of MC was relatively high and could cover soil surface fastly. The initial growth rate of CC was relatively slow, but finally could cover soil surface well, thick and remain in a long time. Biomass in CA was 2.9 Mg ha\u27, MC was 2.6 Mg ha-\u27 and CC was 2.1 Mg ha-1. The organic matter and nutrient contents in the total biomass of LCC that could be supplied to the soil were 1,160-1,680 kg ha-\u27 for C30.-41 kg ha\u27\u27 for N,1.5-2 kg ha-1 for P,18-21 kg ha-1 for K, 9-12 kg ha.-1 for Ca, 0.70.9 kg ha-1 for Mg and 0.2 kg ha-\u27 for Fe at 4 months after planting (MAP). Organic matter and C, N, P, K, Ca, Mg and Fe content were higher than the other crop. Soil characteristics were affected by LCC, especially in the top layer. The concentrations of total-and available nutrient in the soil under LCC were relatively higher than control. Legume cover crops could increase the nutrient\u27s availability and become a good soil amendment for the forest land.

Isolation and Selection of Rhizobium Tolerant to Pesticides and Aluminum from Acid Soils in Indonesia

Application of Rhizobium as inoculum in acid soil requires specific characters, namely high tolerance to pesticide residues, soil acidity, and high concentration of Aluminum. This study was conducted to isolate Rhizobium having these characters. Inspite of acid soils from Kalimantan, Sumatra, Sulawesi and Java; root nodules of legumes planted in those regions were used as source of isolates. Rhizobial isolation was done using direct isolation andenrichment technique. A paper disc diffusion technique was used in selecting tolerance to pesticides. The selected isolates were examined the tolerance to pH, Al, and ability to form root nodule with soybean. From soil analysis, it could be seen the correlation between pH value and Al concentration. It means that the lower pH value the higher Al concentration. The number of Rhizobium isolates and its tolerance to paraquat was depended on soil type. From 173 strains of isolated Rhizobium, 24 strains were tolerance to pesticides and Aluminum. They were able to grow in wide range of pH, namely 3 – 8, or some of them in 5 - 8. Around 92% of the selected bacteria could form root nodules with soybean plant in different number and size. Hopefully, these isolates can be applied in the pesticide polluted agricultural lands, especially in acid soils with high concentration of Al, and it can also increase soybean production.Keywords: Acid soils, aluminium, Rhizobium, pesticide
