RESPON PRODUKSI KELAPA SAWIT DALAM PANENTUAN DOSIS OPTIMUM UREA DAN MOP PADA TANAH TYPIC PALEUDULT

Determination of the optimum dosage of urea fertilizer (source N) and MOP (source K) in oil palm producing (TM) plants through fertilization experiments in the field is very important because the plant needs for both types of fertilizers are relatively high. N-K fertilization trials on TM (aged 4-12 years) have been conducted at one location of PT.Salim Ivomas Pratama Tbk & Subs (in two gardens: Lubuk Raja Estate and / Balam Rumbia Estate) during the 1992-2000 time period. The urea and MOP fertilization treatments separately showed the response of FFB production by 22 and 50%, respectively (1995 - 2000). The interaction of urea and MOP is not real. The response curve of FFB production to urea and MOP doses showed that the optimum dosage in Typic Paleudult soil types for TM aged 7-12 years was 2.50 kg urea and 3.00 kg MOP / tree / year to achieve the production target of 28 tons of FFB / ha /year.To get the maximum fertilizing effect, fertilization must be done by using the type of fertilizer, the correct method and time of fertilization, and with fertilizer quality that is in accordance with specifications (for example SNI or Indonesian National Standard). An examination of the quality of fertilizers is important so that the company avoids multiple losses that have a large impact on production.

TEKNOLOGI TEPAT GUNA PENERAPAN HYDROCOOLING DAN PENYIMPANAN DINGIN UNTUK MEMPERPANJANG UMUR SIMPAN BUAH DAN SAYUR YANG TERKENA ERUPSI GUNUNG SINABUNG

The effect of Mt. Sinabung eruption has profoundly affected the quality of fruit and vegetable production, in this context is fruit and vegetables. Fruit and vegetable, carrot, strawberry and pakcoy is kind of fruit and vegetable that is consumed by the community especially the communities surrounding both the mountain ranges and the general medan area. The fruit and vegetable are kinds of climateric and the lifespan must be kept. During the transportation of field to market, there wa both mechanical and physical damage.The damage will obviously harm farmers, merchants, and other marketers. So that hydrocooling is applied as a post harvest treatment. Hydrocooling is done right after the harvest, This prosess extracts heat from fruit and vegetables so that respiration and transpiration can continue for a long time.The lack of farmer understanding for post harvest handling is a major problem. Therefore, farmers in aberastagi will be given education and training about post harvest handling (hydrocooling) so they could understand and self applying that will keep their produce fresh. As for the output of this activity is a simple hydrocooling device designed as a visual aid in training. This hydrocooling equipment can also be a reference to training science for schoolchildren in particular agriculture schools and could be a referenceto researchers and developing them.

DAMPAK SOSIAL EKONOMI PENGARUH ERUPSI SINABUNG TERHADAP PENDAPATAN, PENDIDIKAN DAN KESEHATAN MASYARAKAT DI KABUPATEN KARO

In this study, there are several things that can describe the socio-economic conditions of farmers having differences in income, education, and health levels, among others: 1. The highest level of income is in Siosar Suka Meriah Village, because they receive government assistance in the form of land, funds , subsidized fertilizers, and seeds, while in Kuta Tengah Village Shelter the income is lower because the government only provides temporary shelter. The lack of capital also caused the lack of income and land to not allow farming because it was located on the slopes of Mount Sinabung. 2. The education level in Siosar Suka Meriah Village is lower, because after moving to relocation the distance to school is too far and some children do not want to continue their education. Whereas in Kuta Tengah Village Shelter their education is higher, because the distance to school is not too far away and most children also have the desire to go to school. 3. The health level in Siosar Suka Meriah Village and the level of health in the Kuta Tengah Village Shelter together use BPJS / KIS which is programmed by the government for the Mount Sinabung eruption refugee community.

PERFORMA PRODUKSI KEBUN KELAPA SAWIT RAKYAT PADA DATARAN TINGGI

The limitation of mineral land as a productive land makes some people expand oil palm cultivation to peat land in marginal class conditions (Class S3). The expansion of oil palm plantations into peatlands is accompanied by Government Regulation No. 57 of 2016 concerning Protection and Management of Peat Ecosystems. The regulation has a positive effect to protect and restore the hydrological function of peat, but also affects the management of oil palm cultivation. The limitation of peatlands also makes some people switch to using the highlands as a form of agricultural and plantation extensification. Planting oil palms in the highlands is a form of expansion of oil palm cultivation that is limited due to lack of sufficient land availability. It is necessary to carry out technical culture and cost requirements that are "more" in order to obtain the same production resembling the treatment of oil palm technical culture in very suitable class land conditions (Class S1). Some state-owned companies have planted oil palms in the highlands. Some state-owned plantation sites have even been converted to oil palm from other plantation crops. This will certainly be very different if done by farmers (smallholders) who are in the highlands. Farmers' knowledge of technical culture and the high amount of funds that will be used to cultivate oil palms are an inhibiting factor other than marginal land class.
