Land use does not the rules of soil and water conservation potentially lead to land causes of degradation that will eventually lead to critical land. The impact ofthe existence of critical landis the decrease of soil fertility, lack of water resoucesin dryseasonandin rain season. Critical land mapping is necessary to determine the right efforts in the management of upper course of Binanga Lantang Sub Watershed until not distrub ecosystem balanced.This study aims to identify the extent and distribution of critical land and formulate appropriate land use directions to suppress degraded land in Binanga Lantang Sub Watershed. The method based on Forestry Departement P.4/V-SET/2013 by overlap method, scoring and weighting of each parameter. The parameters used are map of vegetation class, productivity class map, class map slope, erosion class map and class map management. Reseach results show (1) Classification of critical land after land use direction Binanga Lantang Sub Watershed is very critically broad area 2870,38 ha, critically area 3541,11 ha, rather critically area 4962,34 ha, critical potential 3121,75 ha and not critically area 170,95 ha. (2) critical land Binanga Lantang Sub Watershed to reach 43,72 percen of the total watershed area. The entire production forest area is critical, the protected forest arund 50 percent of the area is in critical condition and other uses are only 20 percent of the area is in critical condition. (3) One of the efforts that can be done to minimize the increase in land criticality is agroforestry and rehabilitation.

This study aims that knowing the level of resistance of several rice varieties to stem borer in organic and inorganic input paddy ecosystems. The research was conducted in the rice fields of Nonong Village, Batui District, Banggai Regency, from March to June 2020. The research used the Split Plot Design method. The main plot was the rice field ecosystem, namely organic input rice fields and inorganic input rice fields, while the subplots were 4 types of rice varieties, namely: Ciherang, Cisantana, Ciliwung and Towuti. Each treatment unit was repeated three times in order to obtain 24 experimental units. The results showed that the towuti variety planted in the paddy field ecosystem with inorganic input was more resistant to rice stem borer. The intensity of attack and the population of stem borer in the lowland organic matter input ecosystem was higher than the inorganic input lowland ecosystem. There is no interaction between rice varieties and types of paddy ecosystems (input of organic and inorganic materials) on the intensity of stem borer attack and the results of production

The study of degraded areas n the pattern of ecosystem restoration in the wildlife comma area of the Takalar district is a study that examines the location of degraded sites in wildlife reserves before ecosystem restoratioan activities in the area. This study aims to identify the extent of degraded sites, know the type of damage that occurs in a degraded location and determine the recovery pattern to be implemented. The area of degradation in the wildlife reserve in Takalar district is 298.84 ha, from the results of visual identification/image in 2016 then conducted direct measurement of wildlife sanctuary Ko’mara with an area of 122.65 ha. Determination of the type of damage to the degraded site is done by inventory of stand to determine the number of nature regeneration/seedlings, stable diameter 10 cm to 20 cm and stands ≥ 20 cm in diameter. The result of the stock inventory shows the type of damage to the degraded location in the Ko’mara wildlife reserve of Takalar district is moderately damaged with plant enrichment recovery pattern.

Segregation pattern of the chloroplast genome in somatic hybridization potato between S. tuberosum cv. BF-15 and the wild species of S. stenotomum was identified through RFLP analysis in 3.2 kb fragment produced from PCR amplification for specific regions of DNA chloroplast. PCR amplification was performed by using rbcL primer and ORF106, i.e. specific primer located on konsenrvatiive sequence which flanking 3.2 kb fragment region of DNA chloroplast. PCR amplification product used two primers, in conformity with the target region on DNA chloroplast, where generated fragments or DNA bands with a size of about 3.2 kb. The 3.2 kb fragment produced from amplification was cut by using two kinds of restriction enzymes HhaI and RSAI. Restriction Enzym treatment with HhaI resulted in four bands each measuring; those were 2.0 kb, 1.2 kb, 0.8 kb and 0.4 kb. While the treatments by using RSAI restriction enzymes, also resulted in four bands each measuring, those were 1.6 kb, 0.7 kb, 0.3 kb and 0.2 kb. Band pattern that produced from restriction enzyme showed that monomorphic nature or not polymorphic at all elder fusion plant, so this method can not be used to identify the patterns of chloroplast genome segregation in plant which is produced by somatic hybridization.

Sweet corn is a type of corn that has special characteristics because of its high sugar content so it can be used in various types of food, including snacks, various kinds of vegetables, corn sugar, and so on. Based on this, the demand for sweet corn is increasing so efforts are needed to increase production by increasing the correct population density per unit area and using the right type of manure. This study aims to get the population density and the right type of manure to increase the growth and production of sweet corn plants. This research was conducted in Lera Village, Wotu District, East Luwu Regency, South Sulawesi Province, starting in July-October 2019. This research used a factorial of 2-factor of the randomized block design method. The Factor I: population density (P) consists of 3 levels, namely: P1 (one plant per clump), P2 (two plants per clump), P3 (three plants per clump), and factor II is the type of manure (A) with 3 types, namely: A1 (chicken manure 15 t/ha), A2 (cow manure 15 t/ha), A3 (goat manure 15 tons/ha), so that 9 treatment combinations were obtained, repeated 3 times. The results showed that the interaction of two plants per clump and the application of chicken manure gave the best results on cob production with husks per hectare.
