Regency of Deli Serdang in the Province of Sumatera Utara has high diversity of landrace rice that has adapted to various climatic and edaphic condition including drought. Studies on various local rice genotypes tolerant to drought is of important to be carried out. This will help plant breeders with germplasms for future breeding program. Polyethylene glycol (PEG) is a water-soluble compound with high osmotic pressure and unlikely to have specific interaction with biological chemicals. With these properties, PEG is often be used in studies of plant response to drought stress. The experiment reported here was aimed at determining rice genotypes, local to Regency of Deli Serdang, tolerant to drought. The experiment was carried out at Laboratory of Physiology and Glass House of Faculty of Agriculture, Universitas Islam Sumatera Utara, Medan from February to April 2020. A two-way factorial experiment was assigned in a completely randomized design (CRD) with 3 replicates. The first factor was 23 local rice genotypes plus 4 genotypes tolerant to drought and the second factor was the concentration of PEG 6000 i. e 0 and 20% (w/v). Observations included percent of germination, plant height, length and number of roots protruding from paraffin-wax layer, leaf chlorophyll content, seedling fresh and dry weight, index of tolerance, probability of resistance, and proline content. Data were analyzed with analysis of variance and mean separation of DNMRT at 5%. Results demonstrated that 6 local rice genotypes, Gemuruh, Ramos Merah, Arias, Sialus, Silayur, and Sirabut were resistant to drought stress under the experimental condition.

Oil palm (Elaeis guineensis Jacq.) has become the main plantation commodity in Indonesia. Climate change phenomena and competitiveness fluctuation of palm oil commodities have led to increased need for optimized land productivity while maintaining sustainability. This research aimed to study the potential of oil palm intercropping with liberica coffee (Coffea liberica L.) in several smallholder oil palm plantations in Riau Province, Sumatera Island, Indonesia. Measurements in the middle of the non-harvesting path of oil palm showed the age of oil palm is directly proportional to the difference between air and soil temperature and relative humidity under canopy. Oil palm roots were dominantly distributed vertically in solum 0 - 30 cm and always dominant compared to coffee at all horizontal distances observed. While the dominant root coffee distribution was in solum 31 - 60 cm. Analysis results show the tap roots extend no further than 30-45 cm below the soil surface. It was known that oil palm roots are dominantly distributed at a distance of 2-3 m from the trunk while the coffee roots are dominantly distributed at a distance of 1-2 m from the trunk. Analysis of oil palm yields in the intercropping system showed no significant decrease compared to monocropping systems with relatively the same age and production input. Coffee production per tree has decreased by 25-30% compared to the average production in monocropping systems.

Jack bean (Canavalia ensiformis), Indonesian local bean, has a high content of protein and great potential either for substituting or overcoming the shortage of imported soybean in tofu production. However, an appropriate coagulant in a proper amount is needed to make tofu with acceptable characteristics. This study set out to investigate the appropriate type and concentration of coagulant. The experiment was carried out by using GDL (glucono delta lactone) and nigari as coagulants with concentration levels of 0.25; 0.5; 0.75 and 1%. Some quality parameters such as yield, color, texture (hardness, cohesiveness, chewiness, springiness), and microscopic structure of tofu were observed. Consumer preference tests on aroma, color, taste, texture, and overall acceptability were directed to determine tofu with the best characteristics. The result showed nigari at concentration level 0.75% delivered the most preferred tofu for consumers.

The SWC and the SBD play an important role in determining soil’s suitability for agricultural uses because they affect various physical, chemical, and biology of soil properties. This field experiment aimed to investigate the reciprocal effect of the SWC and the SBD on the growth and yield of onion (Allium cepa L.). The experiment was layout in a randomized complete block design (RCBD) with three replications. This experiment consisted of one factor, namely, water (A) with four levels, namely, (A0=0 liter, A1=4 liters, A2=8 liters, and A3=16 liters), and one variety endemic of local Tomia (V). The treatment consisted of A0V, A1V, A2V, and A3V. Parameters observed including plant height, leaf width, fresh bulb and dry bulb weight. The results showed that the different water levels treatment had a highly significant (p<0.01) affected the SWC and SBD. Also, simultaneously the SWC and the SBD had a high significance (p<0.01) reciprocally influenced the plant height, leaf width, fresh and dry weight of onion. When the SWC increase, the growth and the yield of onion increase, and when (SBD) decreases, the growing and the yield parameters increases. The best result occurred at the pair of SWC and SBD values of (28.52 %, 1.2 g.m3) with 33.07 cm plant height, 1.3 cm leaf width, 51.67 g fresh weight, and 44.33 g dry weight, followed by other pair of values of SWC and SBD. Through graphs, the analysis showed that SWC has a positive effect and SBD has a negative influence on the growth and yield of onion except at an appropriate value.
