Abstract

ABSTRAK Derajat perkawinan silang bakau bandul (Rhizophora mucronata Lamk.) dari beberapa pohon induk yang tumbuh di hutan alam Sumatera, yaitu Sumatra Utara, Riau, Jambi, dan Jawa, yaitu Muara Angke dan Ujung Kulon, diduga menggunakan isozim. Enam sistem enzim dicobakan dalam penelitian ini, masing-masing AAT, ADH, EST, IDH, MDH, dan PER. Hasil penelitian menunjukkan bahwa bakau bandul memiliki sistem perkawinan campuran, dengan perkawinan sendiri sebagai sistem perkawinan utama, karena perkawinan silang hanya berkisar antara 6-32%. Populasi-populasi pada hutan yang tidak mengalami kerusakan berat (Sumatera Utara, Jambi, dan Ujung Kulon) memiliki derajat perkawinan silang lebih tinggi (32%, 17%, dan19%) dibandingkan dengan populasi-populasi yang hutannya mengalami kerusakan berat (Riau dan Muara angke) yang besarnya masing-masing adalah 13% dan 16%. Rasio polen(serbuk sari) dan ovule(sel telur)beragam antar  lokus  dan  alel,  tetapi  menunjukkan pembentukan gamet  jantan  dan  gamet  betina  yangberimbang. Bakau bandul walaupun cenderung untuk selfing(menyerbuk sendiri), tidak memiliki sistem perkawinan berpilih (F = - 0,197), karena setiap alel pada ovule dan polen dari pohon-pohon bakau bandul yang berlainan berasosiasi secara acak. Angin dan serangga tampaknya berperan penting terhadap terjadinya penyerbukan silang.

Abstract

Land of coal post-mining is the critical area that generally can not becultivated due to very low levels of fertility of the land, so this landbecomes slighted. One of the alternatives to overcome this problem isthrough inoculation with Arbuscular Mycorrhiza Fungi (AMF).Indigenous AMF (from coal post-mining location) is more potential AMFdeveloping in that area. Therefore, isolation, identification and purificationsteps of AMF spores are required. The objective of this study was toisolate, identify, and purify of arbuscular mycorrhiza fungi from coal postmining area. The study had identified that at this soil was found 3 AMFgenuses, i.e. Glomus, Acaulospora, and Gigaspora. On coal post-miningsoil was found 20 strains of AMF (13 strains of Glomus, 3 strains ofAcaulospora, and 1 strain of Gigaspora). In this soil was dominated byGlomus. Strain’s AMF that was successful isolated from single sporeculture was 4 strains i.e. Glomus sp-3, Glomus sp-6, Glomus sp-15, danGlomus sp-16.

Abstract

Deforestation and fragmentation of mangrove forests in Indonesia are widespread that resulted in losing biodiversity including genetic variation. Rhizophora mucronata Lamk. is a common mangrove species in Secanggang, Langkat, North Sumatra and have been degrading due to anthropogenic disturbance. The aim of this study is to determine the genetic variation in natural population of R. mucronata in Secanggang, North Sumatra using isozyme markers. From five enzymes systems used namely aspartate aminotransferase (AAT), alcohol dehydrogenase (ADH), esterase (EST), malate dehydrogenase (MDH), and peroksidase (PER); eleven loci was found and five polymorphic loci were detected.The estimate value of genetic variation parameters i.e. observed and expected heterozygosity, average alel per loci, and average polymorphic (95% criteria) were 0.1386, 0.1724, 1.5455, and 45.45 % respectively.The low genetic variation of R. mucronata found in this study suggested that genetic variation may be influenced by anthropogenic activities such as illegal logging, conversion into shrimp pond and agricultural farm.Keywords: Anthropogenic, genetic variation, isozyme, mangrove, Rhizophora mucronata

Abstract

Environmental services are activities to utilize the potential of natural resources by not damaging the environment and its main function. One of the utilization of environmental services is the utilization of water flow services and water utilization. Humans in their life processes use water for drinking, cooking, washing, and all other activities directly related to human welfare. This study aims to determine the factors that influence people's willingness to pay for environmental services, look for the value of Willingness To Pay (WTP), factors that influence the value of PAPs and the effect of the value of environmental service benefits on payments for environmental services. The willingness of respondents to make payments for environmental services is influenced by several factors, namely an assessment of the level of water quality, the amount of water needed in the household, and the average income in the household. This study aims to determine the factors that influence people's willingness to pay for environmental services, look for the value of willingness to pay (WTP), factors that influence the value of PAPs and influence the value of the benefits of environmental services on payments for the environment services. The willingness of respondents to make payments for environmental services is influenced by several factors, namely the assessment of the level of water quality, the amount of water needed in the household, and the average income in the household. The PAP value in this study is the value that will be given by respondents to the environmental services produced by the Lubuk Beringin Village Forest per cubic meter per household. The average value of PAPs for environmental improvement as water service services in the Lubuk Beringin Hamlet is Rp. 4,439, - / m3. The factors that influence the respondent's WTP value are influenced by the assessment of water quality level and average household income. The total value of PAPs from the population is Rp. 1,406,143 per month. The data shows that there are funds that can be used for 1 year of Rp. 16,873,716. The funds can be used to conserve the Village Forest area as an effort to maintain the environmental conditions of the Lubuk Beringin Village Forest as a provider of water use services by the community in the Lubuk Beringin Hamlet.

Abstract

ABSTRACT Forest and peatland fires in the tropics occur on a large scale and cause environmental damage in the lungs of the world. The flames on the burning peat mix with water vapor inside the peat and produce a lot of smoke. The carbon which was previously buried in the soil and stored in stands above it became exposed and united in the life and human environment. It is very important to know the total carbon stocks in peat to see its contribution as carbon sequestration and carbon storage in stabilizing the ecosystem for rehabilitating peatlands in the tropics which are the lungs of the world. This research is limited to the estimation of carbon stocks stored in peat and understorey soil at the rehabilitation site of the Orang Kayo Hitam forest park. The estimation of soil carbon stocks is carried out by measuring the depth of peat at 48 drill points that are systematically placed. The estimation of understorey carbon stocks is carried out by destructive sampling method on a 0,5 x 0,5 meter plot which is repeated 3 times. The results showed that the peat depth varied from 7,2 - > 10 meters. The mean of understorey carbon stocks is 7.74 tons/ha while the mean of soil carbon stocks is 33.183,67 tons/ha.
