Abstract

AbstractUtilization of natural resources in the form of coal mines has a positive impact on economic and energy development, in addition to coal mining activities have a negative impact on the environment that result in environmental pollution in soil, water, and air. Pollution begins when clearing land, taking exploitation, transporting, stockpile and when the coal is burned. When land clearing causes damage to forest ecosystems. At the time of exploitation impact on air pollution by coal dust particles, the erosion, siltation of the river, the pollution of heavy metals and the formation of acid mine drainage (AMD). The high acid conditions cause the faster heavy metals such as Hg, Cd, Pb, Cr, Cu, Zn and Ni present in the coal dissolved and carried to the waters. Coal stockpile activity also causes pollution in the air, soil, and water. At the time the coal is burned as an energy source causes the emission of hazardous materials into the air of Hg, As, Se and CO2 gas, NOx, SO2. This condition has an impact on the environment and ultimately on human health. Keywords: coal, pollution, heavy metal, gas emission  Abstrak (Indonesian)Pemanfaatan sumber daya alam berupa tambang  batubara berdampak positif dalam pembangunan perekonomian dan energi, disamping itu aktivitas penambangan batubara berdampak negatif bagi lingkungan yang berakibat pencemaran lingkungan di tanah, air dan udara. Pencemaran dimulai ketika membuka lahan, pengambilan batubara (exploitasi), pengangkutan, penyimpanan sementara (stockpile) dan saat batubara tersebut dibakar. Ketika pembukaan lahan untuk penambangan batubara, hutan mulai di tebang sehingga menyebabkan kerusakan ekosisitem. Pada saat exploitasi berdampak pada tercemarnya udara oleh partikel debu batubara, terjadinya erosi, pendangkalan sungai, pencemaran logam-logam berat dan terbentuknya air asam tambang (AAT). kondisi asam yang tinggi menyebabkan semakin cepat logam-logam berat seperti Hg, Cd, Pb, Cr, Cu, Zn dan Ni yang ada pada batubara tersebut terlarut dan terbawa ke perairan. Aktivitas penyimpanan sementara (stockpile) batubara juga menyebabkan terjadinya  pencemaran di udara, tanah dan air. Pada saat  batubara tersebut dibakar sebagai sumber energi menyebabkan emisi bahan berbahaya ke udara berupa Hg, As, Se dan gas CO2, NOx, SO2. Kondisi ini yang berdampak pada lingkungan dan akhirnya pada kesehatan manusia.  Katakunci : batubara, polusi, logam berat, emisi gas.

Abstract

One of the concrete efforts made by the Indonesian government is through social forestry policy as a trigger for land conflicts. One area that has implemented a pattern of social forestry is a forest area located in the management area of the Regional Technical Implementation Unit(UPTD) KPHRegion I Meranti located in Musi Banyuasin Regency. Only 3 social forestry scheme permits have been issued. So the aims of this study was to find out and analyze the process of implementing social forestry policy and analyze the factors that influence. The study was conducted in Pangkalan Bulian and Lubuk Bintialo Villages, Batang Hari Leko District, Musi Banyuasin Regency, South Sumatra Province. Used descriptive method combined (mixed methods) from two different approaches namely quantitative or qualitative approaches. Funding and staff resources (human resources) are still lacking. The process of collective action between actors is running well with the existence of a committed PPS Working Group. Technical rules are clear with the existence of SOPs that are derived from the rules of government and local government.Communication goes well between communities (Forest farmer groups and cooperative members) - local government and facilitators, but not so well between government structures (village heads and apparatus and local government.The Social forestry policy in Musi Banyuasin District, South Sumatra has been effectively implemented from the perspective of policy accuracy in resolving forestry problems and environmental accuracy in accepting policies.

Abstract

The objective of this research was to study how much yield difference of fresh fruit bunch of oil palm between dry and rainy season, and whether the yield difference much in dry land compare with wetland. The research was conducted in Entisol of PTPN VII Betung, and in Ultisol of PTP Hindoli, both in Sungai Lilin Regency. Yield data used in this study was data of year 2007−2010. Rainfall data during 2007−2010 showed no absolute dry month during dry seasons. The result of the study indicated that yield in dry land higher than in wetland either in dry season or in rainy season. Yield fluctuated between dry and rainy season either in dry land or in wetland. But, yield in rainy season did not consistently higher than in dry season. It was concluded that oil palm yield was influenced not only by soil water supply and rainfall quantity, but also internal and many other external factors.

Abstract

The objective of this research was to study the effect of nutrient fertilization on the growth and development of nepenthes (Nepenthes mirabilis). The research was conducted from October 2011 until March 2012 at Sukarami village, Palembang, Indonesia. Factorial randomized block design with two treatment factors was applied. The first factor was NPK fertilizer dosage which consisted of three levels: Po = no fertilizer, P1 = 5 g, P2 = 10 g. The second factor was number of ants: S0 = none, S1 = 20, S2 = 40, S3 = 60. The results indicated that NPK fertilizer application of 5-10 g to the planting media could increase plant growth and development, particularly in plant height, stem girth, and leaf number of N. mirabilis. Giving 60 ants per plants into nepenthes pitcher could yield the largest pitcher number, 3-4 pitcher per plant. Combination of 5 g NPK and 20 ants, similarly, combination of 10 g NPK and 0 ants resulted in the largest leaf increment (10-11 leaves). Combination of 0 NPK and 60 ants resulted in the largest pitcher number (3-4 pitcher per plant).

Abstract

Surahman H, Sulaksono G, Sembiring Z, Kurnianingsih A, Priadi DP, Asmono D. 2020. Effect of plant gowth regulator on the gowth of zygotic embryos in three types of oil palm fruit (Elaeis guineensis Jacq.) in tissue culture. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 149-159.Embryo culture is a widely used and effective way of overcoming the dormancy nature of seeds in oil palm.  At the germination stage, the influence of gowth regulators play an important role although in relatively lower concentrations in the germination media. This aim research determined the effect of adding various concentrations of gowth regulator on the three types of oil palm fruit based on the thickness of the shell. This research carried out at the Tissue Culture Laboratory of PT. Sampoerna Ago Tbk. from September 2018 to January 2019. The gowth regulator substances used in this study were NAA, BAP and GA3. The composition of the gowth regulators used were H1 = 0.05 mg/L NAA + 0.1 mg/L BAP + 0.1 mg/L GA3, H2 = 0.05 mg/L NAA + 0.3 mg/L BAP + 0.1 mg/L GA3, H3 = 0.05 mg/L NAA + 0.5 mg/L BAP + 0.1 mg/L GA3 and H4 = No gowth regulator. While the types of oil palm fruit used were C1 = Dura, C2 = Tenera and C3 = Pisifera. This research used a factorial complete randomized design with three replications. The results showed that in general the use of gowth regulator substances H1 = 0.05 mg/L NAA + 0.1 mg/L BAP + 0.1 mg/L GA3 and the type of dura fruit showed positive results based on viability, scoring, survival and height of plantlets when compared with other treatments.
