Abstract

Marpaung et al, 2019. Utilization of Upland Rice as Intercropping Chilli Plant in North Sumatra Province (case study in North Sumatra Karo District). pp. 442-448.Rice is one of the main comodity that the government always seeks to increase. This research was to  study utilization of upland rice as intercropping chilli in North Sumatra Province.  The decrease in rice field area for rice plants needs to be an effort to increase  rice production, one of them is by using intercropping between chilli plants. Rice cultivation as a chilli crop carried out by upland farmers in North Sumatra can provide farmers income of  Rp. 3.809.000/ 2000m2 with R/C ratio 1.74 compared to just monoculture. The intercropping of rice and chilli plants carried out for farmers is a means of fertilizer production that is more efficient and easier to use. OPT for chili plants.

Abstract

Prasetyo et al, 2019. Performance of Palm Oil in Dry Season in South Sumatera: Effect of Fertilizer on Vegetative Growth and Status of Nutrient. pp. 60-66.Most of the oil palm plantations in South Sumatra Province are planted in acid soils (Ultisol and Oxisol). The main limiting factor in acid soils is high acidity with low fertility. This condition is coupled with the typical climate conditions in South Sumatra, namely the existence of a strict boundary between the rainy and dry seasons. When the dry season, it is not uncommon to find water deficits. This study was conducted to determine the relationship between water deficit events and vegetative growth and nutrient content of oil palm. This study was carried out by exploiting data in fertilization experiments. Fertilization experiments using factorial design N3P2K3Mg2 (higher order partially confounded interactions) and each plot consisted of 64 trees. The results of the study showed that in general the water deficit events in 2014 decreased 4-6 frond per year in the same year and decreased 2-6 frond per year in 2015. Increased K content in the leaves will increase frond production. The optimum K content to maintain a fixed 24 frond production is 1.1%. This study can be used as initial information for management of fertilization management in the event of a water deficit.

Abstract

Herlinda et al, 2019. Development of Biological Control for Pests of Oil Palm and Rice-Corn-Soybean. pp. 1-12.Biological control for  pest insects is an activity of predator, parasitoid or entomopathogen in decreasing pest populations, it makes the populations lower. This paper was written based on information and both primary and secondary data. The development of biological control in oil palm plantations was currently dominated by conservation of predatory arthropods and parasitoid by utilizing refugia. The refugia that were widely used were Turnera subulata, Turnera ulmifolia, Antigonon leptopus, and Cassia cobanensis. In addition to refugia, palm oil plantations currently utilized a lot of entomopathogens, both entomopathogenic fungi and viruses. Entomopathogenic fungi that had been widely developed were Metarhizium anisoplia, Metarhizium majus, and Cordyceps militaris, while entomopathogenic viruses were used, such as the Nudaurelia ß virus and Multi-Nucleo Polyhydro Virus (MNPV) and Rhabdionvirus oryctes. The use of parasitoid in oil palm plantations was not as intensive as the use of entomopathogen and refugia. The development of biological control in rice, corn, and soybeans (“pajale”) generally used  conservation approach for natural enemies that prioritized habitat management, for example intercropping which was able to provide habitats and niches for predators and parasitoids. The use of entomopathogens to control pests in “pajale” was less intensive because it is constrained by the micro climate in “pajale” ecosystems was less ideal,  due to fluctuations in temperature and humidity are relatively more higher than in the oil palm ecosystem. The predators that were dominant in “pajale” were hunter spiders, for example Pardosa pseudoannulata while predominantly parasitoid was oligophagous or polyphagous parasitoids.  Thus, it can be concluded that the development of biological control in oil palm and “pajale” is slightly different, in oil palm natural enemies are easier to settle because the ecosystem is more stable, whereas in “pajale” ecosystems, the natural enemies of the entomopathogens are less able to settle due to less stable micro climate.

Abstract

Saputra et al, 2019. Effect of Different Types of Feed on Albumin Content and Survival of Snakehead Fish (Channa striata). pp. 394-401. Albumin plays an important role in maintaining plasma osmotic pressure and helps host recovery process due to a disease caused by a lack of blood protein. The availability of blood protein in sufficient quantities can help maintain fish health performance. Healthy fish produce high survival values. This study was conducted to determine the effect of different types of feed given to survival and albumin levels of snakehead fish. The treatment given in the form of P1 snakehead fish was given commercial pellets with 32% protein, P2 snakehead fish was given commercial pellets with 32% protein plus 3.5% black cumin and P3 snakehead fish was fed in the form of fresh water and sea water trash paste in comparison 1: 1. Fish are kept in hapa in concrete ponds for 30 days. Feeding is carried out three times a day at satiation. Fish maintenance was carried out at the Laboratorium Kolam Percobaan Faculty of Agriculture while measuring albumin levels was carried out at the Laboratorium Bioproses Faculty of Engineering, Srwijaya University. The study lasted from May to July 2018. The results of measurements of albumin levels of snakehead fish were found to produce P3 treatment with the highest average addition of albumin levels of 0.025 mg / ml, while the average addition of the lowest albumin levels was found in fish fed P1 treatment (0.015 mg / ml). The snakehead fish treated with P2 had an average addition of albumin of 0.019 mg / ml. The highest survival rate was found in fish in P3 which was 80%. The snakehead fish in treatment P1 and P2 have average survival values of 72.5% and 73.75%, respectively. The results showed that differences in feed did not significantly affect albumin levels and has significantly affect fish survival rate.
