Optimal nutrient delivery is one way to increase palm oilproduction. This is because the need ofnutrients for palm oil is quite high, while the soil capacity in providing nutrients for plants is limited. Besides fertilization, nutrients can be given in the form o forganic materials added or grown as cover crop. Beans as a cover crop is a vine that can increase nutrients and improve soil quality. Ofthe many types o fbeans as a cover crop, Mucuna bracteata is the most widely used species, because it has several advantages, namely rapid growth, high biomass production, resistant to shade, resistant to drought, suppress the growth ofweeds, and not liked by livestock. Mucuna bracteata also has benefitsforpalm oil crops such as increasing soil fertility, protecting against erosion hazards, improving soil properties and shortening seedling periods. This research was conducted to obtain informative data about the physical and chemical properties o fsoil on slope andflat areas planted with Mucuna bracteata as a cover crop and without Mucuna bracteata. This research was conducted at Afdeeling IKebun Bangun Bandar Socfindo Inc, Tanjung Maria Village, Dolok Masihul Sub-District, Serdang Bedagai District, Sumatera Utara Province. The research was conducted from May to July 2016. This research was conducted by descriptive analysis method that is collecting direct data infield and testing o fsoil samples in laboratory. Soil samples were taken based on: Topography (flat and slopes 15-30%), cover crops (without Mucuna bracteata and with Mucuna bracteata) and plant life (seedling periods 1, 2 and 3). The soil sample is taken composite by zigzagging soil sampling method. The research results showed that the planting of Mucuna bracteata in palm oil plantations was able to improve some physical and chemical properties of the soil; Planting Mucuna bracteata onflat area can fix bulk density o f 12.64%, on slope area o f 6.04%. The color o fthe soil that is planted with Mucuna bracteata tends to be darker than those not planted. The infiltration rate belongs to the class 'very quickly'with a sandy clay-dominated ground texture; Planting o fMucuna bracteata onflat area can increase soil organic matter content by 42.74%, while on slope area o f15.11%, increase ofN-total soil level by 31% and on slope area does not increase N-total.

Paraquat is an active herbicide used to control weeds chemically. This research aim is to determine the effect of herbicide applications with active paraquat matters on the percentage of weed mortality and the number of soil microorganisms. This research used a non-factorial randomized block design with five levels of treatment, that is P0: control; P1: 5 ml of paraquat in 1 litre of water, frequency of application is once a week; P2: 10 ml of paraquat in 1 litre of water, frequency of application is once a week; P3: 10 ml of paraquat in 1 litre of water, frequency of application is once in two weeks; and P4: 5 ml of paraquat in 1 litre of water, frequency of application is once in two weeks. The results of the observations were compiled in a Variety Checklist and continued with the Duncan Multiple Range Test. The results showed that the dominant weeds in the research plot were Ageratum conyzoides, Mimosa pudica, and Paspalum commersonii.The application of 5 ml/l paraquat herbicide, the frequency of application once a week was effective in reducing weed mortality. However, the use of paraquat did not significantly affect the number of soil microorganisms

Tandan kosong umumnya dimanfaatkan sebagai pembenah tanah, disisi lain potensi tandan kosong kelapa sawit dapat dimanfaatkan menjadi berbagai produk yang memiliki nilai ekonomi yang tinggi. Limbah dapur berupa nasi, buah dan sayur banyak ditemukan di tempat pembuangan sampah yang berasal dari pemukiman maupun pasar. Limbah tersebut diklaim sebagai salah satu sumber gas rumah kaca. Penelitian bertujuan untuk mengetahui perkembangan massa maggot black soldier fly dalam biopond berbahan tandan kosong kelapa sawit dan limbah dapur. Penelitian dilakukan di Basmallah BSF Farm Kabupaten Deli Serdang pada bulan Maret hingga Juni 2021, menggunakan rancangan acak lengkap faktorial, dengan dua faktor perlakuan yaitu tandan kosong kelapa sawit yang disusun tiga taraf (tandan kosong utuh, tandan kosong dipotong menjadi empat bagian, tandan kosong yang telah dicacah) dan faktor limbah dapur dengan dua taraf (tanpa limbah dapur, menggunakan limbah dapur), masing-masing 3 ulangan. Hasil pengujian parameter disusun pada daftar sidik ragam dan hasil yang berbeda nyata diuji dengan DMRT taraf 5%. Hasil penelitian menunjukkan larva maggot sulit berkembang pada biopond kering seperti tandan kosong kelapa sawit. Tandan kosong utuh yang dicampur dengan limbah dapur sangat berpotensi dijadikan sebagai biopond maggot, pada biopond ini massa maggot dewasa, pra pupa dan pupa yang dihasilkan lebih besar dibanding perlakuan lainnya. Pemanfaatan tandan kosong tanpa pencacahan dan dicampur dengan limbah dapur menghasilkan perkembangan maggot yang terbaik.
