Abstract

Lakitan B. 2019. Double track strategy for agriculture development in indonesia: facilitating millennial generation and improving livelihood of smallholder farmers. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang  4-5 September 2019. pp. 1-8. Palembang: Unsri Press.Agricultural development in Indonesia has not been able to solve two main fundamental problems. Firstly, advancement of agricultural technology failed to significantly improve livelihood of smallholder farmers; instead, it creates wider gap between developed technology and farmer’s adoption capacity. Secondly, educated young generation who has capacity to employ sophisticated technologies has not interested to work in agriculture sector. In 2018, there were 38.7 million farmers in Indonesia, where as 88.27 percent of them were categorized as informal workers. This number was about one third of total Indonesian workers. They could be time bombs if they are not treated wisely. Their livelihoods should be appropriately improved. The efforts require availability of relevant, affordable, and profitable agricultural technologies. Meanwhile, at present, only few of the millennials interested to work in agriculture sector. This small group of millennial farmers should be encouraged to stay in agriculture, in order to motivate more young generation to follow them. Urban and peri-urban agriculture based on relevant technologies seems to fit well with millennial farmers.Keywords: agricultural development, millennial farmers, welfare of farmers, urban agriculture

Sahara E, Sandi S, Yosi F, Bastian A. 2019. The effect of use chitosan solution in the immersion proces on egg quality. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang  4-5 September 2019. pp. 287-291. Palembang: Unsri Press. Eggs are a commodity of poultry that can be easily damaged if stored at room temperature for a long time.  Chitosan has anti-microorganism properties and can be used to extend the shelf life of eggs. The purpose of this study is to extend the shelf life of eggs by soaking chitosan solution and maintaining egg quality. The study used a completely randomized design (CRD) of 6 treatments, 4 replications and each replication consisted of 2 eggs. The treatment is; P0=0% chitosan, P1=0.5% chitosan, P2=1% chitosan, P3=1.5% chitosan, P4=2% chitosan and P5=2.5% chitosan. Eggs are stored for 14 days at room temperature after being soaked in chitosan solution for 24 hours. The parameters measured are; egg white index,, haugt unit and egg white pH. The results showed that immersion of eggs in chitosan solution 0.5% (P1) gave an egg white index of 0.075 significantly better than the control of 0.05, the highest real haugh unit value of all treatments was 84. The pH of the egg white soaked with Chitosan solution is the same, but lower than the control. The conclusion of this study is the treatment of P1 (0.5% chitosan) shows the best haugh unit value which is 10.71% higher than the control.Keywords:  chitosan, ducks, eggs, quality, solution

Abstract

Priatna SJ. 2019. Utilization of palm oil liquid waste on some changes in the soil physical properties at PT. Waymusi Agroindah palm oil plantation area. in: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 554-558.  Palembang: Unsri Press.Palm oil liquid waste is one type of palm oil waste that has the potential to be reused to improve the quality of the land and support the growth of the oil palm plantations themselves, considering that the potential of this waste is quite large and the elements needed are very important to improve chemical fertility and soil physics.  This research activity aims to determine the effect of palm oil liquid waste utilization (LCPKS) on improving some physical properties of soil. This research was carried out on oil palm plantation areas that were applied to liquid waste, by observing soil samples on two into the soil (0-30 cm and 30-60 cm). Soil sampling is carried out at three sampling points, namely: near the sewage application ditch, between oil palm plants and in the control location. Parameters of observed soil physical properties include: permeability; porosity, texture and weight of soil contents. The results showed that the utilization of liquid waste had an effect in increasing the value of soil porosity (1.3 to 18.25% and soil permeability (25.75% to 78.7%), and reduced the value of soil weight (1.77 to 40.24%), while the texture has no effect, where the results of the texture determination before application and after application have the same texture class, namely: sandy clay to sandy clay loam.Keywords: palm oil, palm liquid waste, soil physical characteristics

Sukamto S, Azizah R, Suprihana S, Karim F. 2019.  Production of high protein noodles using wheat flour fortified with composite flour and mungbean protein. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 487-495. Palembang: Unsri Press. Consumption of noodles in Indonesia in 2018 ranks second in the world after China with consumption of 12.54 billion packs. The amount of consumption of instant noodles has caused an increase in the import of wheat because the main raw material for making noodles is wheat flour. In 2018 wheat imports are predicted to reach 11.8 million tons. To reduce the need for wheat there needs to be an alternative local raw material to replace it. This study aims to utilize cassava and corn flour as composite flour to make instant noodles, where Mung bean protein isolates (IPKH) and Na-alginate are used for binding and gelling agents. The study used an experimental method with factorial randomized block design (RBD). The first factor is mung bean protein isolates and the second factor is Na-alginate. Statistical analysis using variance analysis (Anova) followed by Tukey Test with α ≤ 5% if there is a difference. The results showed that the interaction of the use of 30% protein isolates combined with 0.2% Na-alginate to make instant noodles increased the protein content of noodles to 31.24%, water absorbtion during cooking ranged from 104.66%-157.33%, breaking power before cooking around 55.20 g/cm2-81.33 g/cm2. Taste, aroma and texture based on organoleptic tests rather like to like. Keywords: instant noodles, Na-alginate, protein isolates

Abstract

The potential of swamp land to support national food security has been studied through a desctiptive study. The area of swamp land in Indonesia is estimated at around 34 million hectares. The land consists of tidal swamps of around 60% and the remaining is swamp lowland of about 40%. The land spreads from the island of West Papua in the east to Sumatera in the western part of Indonesia. Of that swamp land area, about 14 million hectares is suitable for agricultural crops. Form the total of swampy area, about 4,92 million hectares has been cultivated for rice plants and around 5,04 million more hectares is suitable for expansion of rice cultivation development. The productivity of swamp land is quite low at around 2-3 tons/ha of hasvested dry grain (HDG). With land improvement, the productivity can be increased to 5-7 tons/ha of HDG. The development of the potential of swamp land can be improved through water management and land improvement technology. This technology is followed by extensification and intensification activities on the land that has been cultivated and the land which is potential for the development of rice plants. The results of the study reveal that with water control and land improvement, the extensification could be increased from 10 million hectares to 20-30 million hectares per year. Rice production is increased from 30 million tons to 60-90 million tons of rice per year. This means that swamp lands have fairly high potential to support national food security.

(Eds), Prosiding Nasiobal lahan Suboptimal 2-019, Palembang 4–5 September 2019. pp 330-337. Palembang: Unsri Press. Organic fertilizers have the ability to increase soil fertility both physically, chemically and biologically, on the other hand the content of organic matter is not enough to meet nutrient requirements for plants, so it is necessary to add biological fertilizers containing bacteria that can help provide nutrients. This study aims to determine the types of organic fertilizers enriched with biological fertilizers with different concentrations in corn plants (Zea mays L.) in tidal land. This research has been carried out on the ground of farmers in Purwosari Village, Tanjung Lago Subdistrict, Banyuasin Regency, South Sumatra Province held from May to August 2018. The research method uses Split Plot Design with 12 treatment combinations and 3 replications. The treatments are as follows: Organic fertilizer (K), K1=chicken manure compost, K2=Cow compost, K3=Rice Straw Compost, and Biological Fertilizer Dosage, H0=No Biofertilizer, H1= 10ml/litter, H2= 15 ml/litter, H3=20 ml/litter. The variables observed in this study were plant height (cm), number of leaves (strands), leaf area (cm), root length (cm) and dry weight of plants (g). The results showed that the combination of the treatment of chicken manure compost and 20 ml/liter biofertilizer doses gave the highest yield with an average yield of 5.58 kg/plot or equivalent to 7.3 tons/ha of  corn shelling.Keywords: biological fertilizer, corn, organic fertilizer
