Abstract

The process of physical and chemical properties of the former gold mining soil which is caused by the transformation of different land conditions in natural rice fields, reclaimed rice fields, and mine fields. This study aims to determine the differences in the characteristics of the former gold mining soil in natural rice fields, reclaimed rice fields and mining fields in Sijunjung Regency. There were three sampling locations with three sample points each and the samples were analyzed physically and chemically. Results of this study showed that natural paddy soil has optimal conditions for the growth of rice plants followed by reclaimed lowland soil and the worst was in mining paddy soil based on soil physical and chemical properties. The difference in soil physical properties in the form of natural paddy soil texture was smoother compared to land conditions in reclaimed rice fields and mining rice fields. This was due to intensive inundation processes, which created a plough tread layer, low volume weight accompanied by a moderate total pore space. The difference in chemical properties was in the stable pH of natural paddy soil due to inundation and high organic carbon accompanied by rice reclamation and very low organic carbon in mining soils, which would affect the growth of rice plant.

Abstract

Land damage caused by gold mining activities is mainly due to soil contamination by Mercury (Hg). Ex-gold mines are soils that have poor chemical, biological, and physical properties, resulting in a very low level of soil fertility. The objective of this study was to determine the effect of rubber leaf litter compost and biochar of oil palm empty fruit bunches to obtain the best dose recommendation in improving the ex-gold mining soil on the growth of rubber seedlings (Hevea brasiliensis Muell. Arg.). This study was designed by a completely randomized design consisted of 7 treatments and repeated 3 times. The treatments were rubber leaf litter compost at a dose of 10 tons/ha and 20 tons/ha, biochar of oil palm empty fruit bunches at a dose of 10 tons/ha and 20 tons/ha, combination of rubber leaf litter compost and biochar of oil palm empty fruit bunches at a dose of 10 tons/ha and 20 tons/ha, respectively. The results showed that the combination treatment of rubber leaf litter compost and biochar of oil palm empty fruit bunches at a dose of 20 tons/ha resulted in a soil pH value of 4,85, Al-dd 0,42 cmol/kg, C-organik 0,92%, N-total 0,053%, C/N 11,25, P-available 122,69 ppm, K-dd 0,40 cmol/kg, and reducing soil mercury by 0,01 ppm. The growth of shoot height and leaves number of rubber seedlings was obtained by the application of biochar of oil palm empty fruit bunches at a best dose of 20 tons/ha. In addition, the treatment of rubber leaf litter compost at a dose of 20 tons/ha was able to increase the leaf width of rubber seedlings (h. brasiliensis Muell. Arg.).

Abstract

Nagari Sungai Abang is one of the areas in Lubuk Alung District, one of the rice production centers in Padang Pariaman Regency. One farming group that intensively cultivates rice is the Farming Business group. The problem with the farmer groups is their ignorance of the benefits of straw as a source of organic matter in the soil. The composting process is long, so farmers always burn rice straw after harvest in preparation for planting the following season. If the burning of straw is carried out continuously, it is feared that nutrients will be deficient in the soil. This activity aims to empower Farming Business groups in Nagari Sungai Abang, Lubuk Alung District, to utilize Plant Growth Promoting Rhizobacteria (PGPR) as a bio activator in making straw compost as organic fertilizer and an alternative to addressing the problem of straw waste in Nagari Sungai Abang, Lubuk Alung. This activity has been carried out in the Farming Group of Farmers in Sungai Abang Dalam Nagari Sungai Abang, Lubuk Alung District, Padang Pariaman Regency. The method used is outreach, counseling, and training to demonstrate making PGPR suspension and compost from straw. From the activities that have been carried out, ready-to-use PGPR is obtained as a bio activator reproduced in coconut water media and used as a bio activator to speed up the composting process. The conclusion of this activity is increasing farmers' understanding of the benefits of straw as a raw material for compost and the use of PGPR as a bioactivator in making straw compost.

Abstract

The percentage of slope classes on a land has an impact on changes in soil physics. The purpose of this study is to evaluate the physical properties of soil planted with tobacco on various slopes in Kenagarian Situjuah Batua, Situjuah Limo Nagari District, Lima Puluh Kota Regency. The method used in this study was a survey; samples were taken purposively based on slope classes at slopes 8-15%, 15–25%, and 25–45% at depths of 0–20 cm and 20–40 cm. From each slope 3 repetitions were taken. The results showed that there were changes in soil physics properties in each slope class with the dominant texture of sandy clay loam. Organic matter was classified as high to low (18.77–3.63%), low soil buld density (0.66–0.34 g/cm3), and total pore space was classified as high (75.27–86.87%). The permeability of the soil was classified as very fast to somewhat slow (34.88–0.78 cm/h), and the aggregate stability index was somewhat steady to less steady (60.89–45.98%). It is recommended that tobacco farmers to make terrracing and cut the length of the slope so that it does not lose organic matter. Keywords: soil physical properties, slope level, tobacco plantation

Abstract

Faktor lingkungan yang mempengaruhi pertumbuhan bakteri endofit adalah pH dan Suhu. Dua unsur lingkungan ini sangat penting diketahui pengaruhnya baik dalam perbanyakan bakteri maupun dalam penggunaannya. Penelitian dilakukan untuk melihat pengaruh suhu dan pH optimum terhadap pertumbuhan bakteri endofit setelah dilakukan isolasi pada jaringan batang, daun dan akar cabai merah (Capsicum annum, L). Rentang suhu yang dicobakan pada kisaran 30 s.d 50oC dengan selang 10oC sedangkan rentang pH media adalah berkisar dari pH 4,0 s.d pH 8,0 dengan interval 0,5. Pertumbuhan bakteri dalam media kultur cair diamati dalam interval waktu 24 jam berdasarkan perubahan OD (optical density) media kultur pada panjang gelombang 600nm dengan menggunakan spektrofotometer. Penelitian menunjukkan respons pertumbuhan isolat endofit yang bervariasi terhadap tingkatan suhu dan pH media yang berbeda. Terdapat variasi lag dan log phase antara ketiga isolate dengan lag phase terpanjang ditemukan pada isolate DN1 pada suhu 50oC. Namun demikian ketiga isolat masih tergolong bakteri mesofilik yang tumbuh optimum pada suhu 30-40oC. Terdapat juga perbedaan pH optimum antara ketiganya dimana isolat AK1 berkisar dari 6,5–7,5, isolate BT1 pada pH 6.0-8.0 dan isolat DN1 pada pH 5.5-6.0. Hasil ini menunjukkan bahwa ketiga isolat berkemungkinan besar bukan spesies yang sama dan menguatkan dugaan bahwa terdapat bakteri endofit yang spesifik untuk masing-masing jaringan tanaman cabai.
