Abstract

Especially in Rokan Hulu Regency, the low productivity of upland rice is caused by the improper planting time. Land dryness often occurs as a result of incorrectly predicting climate which in turn hurts crop yields. This research was conducted to determine the level of groundwater availability based on the analysis of the land water balance and to determine the planting time of upland rice in the Rokan Hulu Regency. The method used in this research is a survey method. The primary data consisted of the water content of field capacity, permanent wilting point, and bulk density. Location of the soil sampling consisted of seven Homogeneous Land Units (SLH) resulted from overlay of soil type map, administrative map, dryland agricultural map using the Geographic Information System technique. Secondary data (climate period 1990-2019) were obtained from Balai Wilayah Sungai Sumatera III. Land water balance analysis was performed using the Thornthwaite-Matter methods. The data obtained were analyzed using descriptive statistics to explain the period of surplus and deficit in groundwater, as well as for determining the planting time for upland rice based on soil water content and plant water needs per growing period at each SLH. The results of the research showed that the Rokan Hulu regency was classified as a wet area with an annual rainfall of 2,751.1 mm (Oldemann C1). Soil water content is classified as very sufficient criteria every month, both topsoil and bottom layer in the range of January-May and September-December. However, in the range of June-August, the soil water content varied at each SLH. Upland rice planting (Inpago Varieties) can be done in January, May, and September in SLH 1, SLH 2, SLH 3, SLH 4, SLH 5, and SLH 6, while in SLH 7 upland rice planting is carried out in January and September. Planting using local varieties can be done in February and September in SLH 1, SLH 2, SLH 3, SLH 4, SLH 5, and SLH 6, while in SLH 7 planting can be done in March and September. Alternating planting can also be done by planting inpago varieties in February and local varieties in September.

Abstract

Generative propagation of onion sumenep cultivars had not provided optimum results. To overcome this problem vegetative propagation was used with tissue culture systems. Growth Regulator (ZPT) 2iP and Coconut Water were used as a source of cytokines to stimulate explant. This research was aimed to observe effect of 2iP and coconut water in stimulating red onion compound shoots. This experiment was carried out using a completely randomized design consisting of two factors. The first factor was the provision of 2iP with five levels of concentration of 0.0, 2.0, 4.0, 6.0, 8.0 mg/l and the second factor was the provision of coconut water with three levels of concentration of 10, 20 and 30%. The parameters observed were shoot number, leaf number, leaf length, root number and root length .The results of this research showed that the combination of 8.0 mg/l 2iP and 20% coconut water resulted in an average number of shoots and the highest number of leaves, each of which was 6.5 shoots and 6.3 leaves at 8 MSP. The combination of 2iP treatment and coconut water gave more significant effect than that of the single treatment.

Abstract

ABSTRACTRice processed from paddy is the main food of Indonesian people in general.Jayawijaya regency is a place that is located in Pegunungan Tengah, Papua Province, can only be connected to the other regencies through air transportation. Rice that is supplied to this regency are varied by quality and brands. Because of those rice supplying condition to this region, automatically, those various rice will be put in storage by both seller and consumer. However, keeping those rice will cause the emergence of pest, in this case, rice lice. Therefore, the purpose of this research was to find out the influence of different types of rice: organic rice, betet rice, and bulog rice to the population of rice lice pest (Sitophilus oryzae) and the rice quality by its storage period in Jayawijaya Regency. This research was conducted in Plant Conservation Laboratory of STIPER Petra Baliem Wamena. This research was conducted for six months which was started June to December 2017. The method of this research was experiment method, and the used design pattern was Random Completed Design. The treatment design was one factor which was consisted of threetypes of rice. Each treatment was repeated by three repeats. The treatment was: types of rice factor: B1: organic rice; B2: betet rice; B3: bulog rice. In this research, there were three treatments, and three repeats so there were nine experiment units. Each unit consisted of packed rice in 0.5 kg plastic for 10 plastics. In each experiment unit, three plastic were taken as samples, so there were 27 rice samples in total. According to the result of the research, we can conclude that bulog rice was able to produce more rice lice (Sitophilus oryzae) and had higher damaging percentage, however, had lesser water and glucose level compared to betet and organic rice.
