Abstract

Herlinda S.  2019. Development of technology for cultivation adaptive crops in freshwater swamps of South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang  4-5 September 2019. pp 20-30.  Palembang: Unsri Press.Freshwater swamps is an ecosystem that is saturated with river water or rain throughout the year. This paper aimed to review the needs of farmers based on technology that could be developed in  the suboptimal wetland or the freshwater swamps, specifically for commodities that were adaptive in the wetland ecosystem in Indonesia, especially South Sumatra. Now, many superior varieties have been invented that were resistant to pests and disease. Rice seedlings in the freshwater swamps generally still used a floating and “samir” system or a combination of both. Soil and planting began to use agricultural machinery, but it needed to be adjusted to the conditions of soil in the wetland. Farmers  generally still used synthetic fertilizers and appropriate technology needs to be used to make compost from local materials. Pumping water management was still constrained by capital but farmers had difficulty managing water, especially in the freshwater swamps which would be drought during the dry season and flooded during the rainy season. Farmers needed dams for their fields so that water could be regulated using pumping. The rice were harvested using a combine harvester. The main problem for drying grains in the South Sumatra freshwater swamps was the scarcity of cheap and practical dryers. In addition to rice, adaptive vegetables in the freshwater swamps were grown, including chili, cucumber, bitter melon, long beans, cloves. Adaptive vegetables in the freshwater swamps that have been neglected by farmers were water lily, Leafy vegetable, and genjer plant. The adaptive rice and vegetables, if developed in an environmentally friendly manner, can improve the welfare of farmers.Keywords: harvest and post-harvest technology, mechanization, seed technology, SERASI

Abstract

Chuzaimah C, Sjarkowi F, Wildayana E, Yunita Y. 2019. Micro perspectives on land conversion implied problems in rawas sub-watershed in North Musi Rawas District, South Sumatera. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 228-235. Palembang: Unsri Press. Musi Rawas Utara District is included in the sub-watershed area (watershed) of Rawas, one of the 14 sub-districts included in the Musi River Basin. Factors influencing land conversion, among them are Sporadic Patterned Gradual Conversions where conversion patterns are caused by two main driving factors (economically less productive/beneficial land and the economic urgency of the convert). This paper aims to analyze the factors that influence the occurrence of land conversion from the micro side in the Rawas Sub-watershed area of North Musi Rawas Regency. This research was carried out in Maur Baru Village, Karang Dapo District and Rantau Kadam Village, Karang Dapo District, North Musi Rawas District. Data collected consists of primary and secondary data. The results showed that from the micro aspect there are several factors that influence the occurrence of land conversion: 1) age of plants, where the average rubber farmer who has older rubber plants prefers to do conversion, 2) Land Area, the average farmer who have a small land area prefer to convert their land 3) The number of family dependents, the average farmer who converts has a greater number of dependents than farmers who do not convert, 4) The distance from home to the land, the farmer who converts take the distance from home to the land further than farmers who do not convert land.Keywords: conversion, land, micro

Bela DV, Latifah S. 2019. MSG-benefits of micin for rice (steady) plants as a food that is chemical-free and environmentally friendly to maintain public health towards a progressing Indonesia. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 502-507. Palembang: Unsri Press.Indonesia is one of the countries that has the largest population in the world, 260,580,739 people whose staple food is rice (cooked rice from rice). Over time, the need for rice is increasing, as a result farmers take a way out by using chemicals to produce maximum harvest, even though the use of chemicals is not good for the health of the body, especially if consumed long and excessive. But in reality in various regions the use of chemicals as fertilizers is still very high. Thus, one way to reduce the use of chemicals in rice plants is by using MSG (Monosodium Glutamate) as a maximum fruit-producing auxiliary material. The content of compounds in MSG can increase water content during the summer or dry and is able to nourish the development of plants. So that MSG can prevent the occurrence of water resistance, fertilize plants and make plants look fresh with greener leaves, dense and healthy rice. So with the use of MSG, besides being environmentally friendly, rice is also free of chemicals.Keywords: environmentally friendly, MSG, rice growth

Yuono AL, Putranto DDA, Sarino S. 2019. Spatial analysis of environmental and hydrological conditions upper komering sub basin relationship with water availability. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 430-436. Palembang: Unsri Press.Potential water resources in the Komering sub-basin (645.49 m3 / sec), in March (Putranto Dinar DA et al, 2015), should be able to increase national agricultural production in South Sumatra. This study aims to analyze spatially the decreasing availability of water in the Komering sub-basin, where the mainstay discharge in August - September, only 43.08 m3/sec. To analyze the reduced mainstay discharge of the Komering sub-basin, due to poor land use practices in the upstream area and the effects of climate variability, it can be analyzed by the Mock method (1978), by analyzing land cover conditions, the value of rain variability, and the amount of evapotranspiration and validation of direct measurements river discharge. Changes in land use for the upper Komering sub-basin, which are used mostly by the population as community plantation areas, have increased the critical condition of the upper Komering sub-basin by 2,517,560 Km2, or about 65.66% of the total upper Komering sub-basin. From the measurement of debit data at the Perjaya weir in the last fifteen years (2005-2019) the biggest mainstay debit value for 2 weeks to two months in April was 241.67 m3/sec, while the smallest mainstay discharge occurred in the first 2 weeks of October at 54,69 m3/sec. A large enough difference between the largest and smallest mainstay discharge, it is necessary to think of a way so that the availability of water is always maintained throughout the year (the mainstay discharge difference between the rainy season and the dry season so that it is not so extreme). Some ways that can be done to maintain water availability include by making water reservoirs during the rainy season, such as reservoirs and reservoirs, or increasing storage in the soil by reforestation and harvesting methode.Keywords: discharge, harvesting, land-use change, resources, spatial

Hutapea Y, Suparwoto S, Suryana Y, Hutabarat P. 2019. Value added weight of cattle based on giving feed in rubber plantation area. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 62-70.  Palembang: Unsri Press. Rubber plantation areas have the potential to provide cattle feed such as natural grass and leftovers from other crops that are cultivated such as corn waste. This potential can be used to support the development of cattle in South Sumatra. This study aims to analyze the added value of cattle weight through several types of feed that can be obtained in rubber plantation areas. The activity was carried out in August - October 2018 in rubber plantation area of Betung Sub-District, Betung District, Banyuasin Regency. The cattle used were 20 male cows with a body weight (BW) of 150-200 kg and around 1-2 years old. Feed treatment (P1) in the form of: fresh grass according to farmer's habits, P2: fresh grass (10% BW) + concentrate (1% BW), P3: fresh grass (5% BW) + corn silage (5% BW) + concentrate (1% BW), and P4: corn silage (10% BW) + concentrate (1% BW). The results of the study show that the highest daily weight gain of cattle was 0.36 kg obtained from P2 treatment, while the lowest was 0.23 kg in P4 treatment. On a maintenance scale of 5 cows for 3 months, feed in the form of fresh grass (10% BW) + concentrate (1% BW) provides the highest added value of Rp 2,598,750 and the combination of natural grass (5% BW), corn silage (5% BW) and concentrate (1% BW) provides added value of Rp. 371,250 compared to the control. Keywords: added value, body weight, cattle, feed, rubber plantation area
