Biomass and Carbon Stock Estimation Inventory of Indonesian Bananas (Musa spp.) and Its Potential Role for Land Rehabilitation

Abstract: Bananas (Musa spp.) are widely cultivated in Indonesia. They are extensively grown in backyards, homegardens, intercropped with short term crops and also in agroforestry sy stem . Potential role of bananas to absorb and store Carbon related to climate change mitigation is rarely studied. An inventory of biomass and C-stock estimation on banana accessions has been conducted in Musa germplasm plots - Purwodadi Botanic Garden, Pasuruan. 4 2 individual banana accessions has been estimated its biomass and C-stock comprises of 5 wild types and 3 7 cultivars. Biomass estimated using non-destructive method ie. allometric equation for banana by measuring its mature stage pseudostem diameter at breast height (dbh). C -stock was estimat e d by crossing its bio mass to averaged value of banana C-stock 0, 46 . The results showed that the biomass and C-stock estimation level were in positive correlations with its plants pseudostem dbH. The conclusions of these research that Kepok Bung cultivar has the highest level of estimated biomass and Carbon stock about 15, 02 kg/plant and 6, 92 kg C/plant and then c ultivars with range averaged C - stock between 3,5 – 3,9 kg C/plant (higher level) are Tlekung, Baflo, and Cici . Musa balbisiana species contributes higher level of biomass and C-stock estimation than Musa acuminata species.

Tree species preference and rehabilitation perspective by local community: Case study in Bondowoso, East Java, Indonesia

Abstract: . Danarto SA, Budiharta S, Fauziah. 2019. Tree species preference and rehabilitation perspective by local community: Case study in Bondowoso, East Java, Indonesia. Asian J For 3: 54-63. Study of community’s preference on tree species used for rehabilitation programs was conducted in Gubrih sub-watershed, Sampean watershed in Bondowoso District, East Java. The aim of the study was to find out tree species that have ecological values as well as are preferred by local community for rehabilitation program in the region. Questionnaires were distributed to respondents chosen randomly (i.e. to minimize bias) to select tree species which have ecological and/or economic values. Result of the study showed that among 62 species of trees listed in the questionnaire, there were 45 species chosen by the respondents. There were 13 species of trees selected by more than 20% of total of respondent (high preferred), suggesting the potential list of species for rehabilitation programs in the region. Local community in Gubrih Sub-watershed have understood the importance of trees as a source of income as well as a measure to conserve environmental functions. This is strengthened with land-use systems they selected which prefer tree-based land-use system, such as in the form of plantation of timber species and agroforestry over dry land agriculture. The findings of this study suggest that there is opportunity in rehabilitating degraded lands in Sampean watershed using tree species preferred by local community under the land use system of timber plantation or agroforestry. Our study demonstrates that similar strategy of incorporating ecological and socio-economic perspectives could be applied to another regional context to enhance the chance of success of rehabilitation programs.

Vegetation diversity and stand carbon stocks in Wana Wisata Tampora, Situbondo, East Java

Abstract: Forest degradation and industrial development have a negative impact on the global climate. Forest vegetation plays a role in absorbing CO2 emissions in the air. The aims of this research are to determine vegetation community structure, plant diversity indices, and estimation of stands carbon stocks in Wana Wisata Tampora, Situbondo district, East Java. The research was conducted using the transect method and measured the diversity indices including Shannon-Wiener diversity index (H'), richness index (R), and evenness index (E), while the carbon stock was estimated using an allometric equation. The results showed that the diversity index value at the ground cover layer was considered high (3.18), while saplings and trees were moderate (2.68 and 2.60). The results of the stands carbon stocks estimation have shown an average value of 145.94 tonnes/ha. Plant species with high Important Value Index (IVI) and carbon contributor including Schleichera oleosa (83.97 and 56.49 ton/ha), Lannea coromandelica (58.88 and 32.35 ton/ha), Tectona grandis (24.72 and 8.5 ton/ha), Azadirachta indica (20.72 and 8.27 ton/ha), and Acacia nilotica (9.40 and 8.39). The results of the research will be useful for local governments as the basis for the development of Wana Wisata Tampora and the management of flora biodiversity.

Abstract: Bawean Island is a small island located between two islands (Java and Borneo). Geographically, the diversity of plants, especially epiphytic plants on this island is very interesting to be studied. This research aims to investigate the diversity of epiphytic plants, focussing on epiphytic orchids, Hoya and Dischidia in Bawean Island Nature Reserve and Wildlife Reserve. It was conducted through an inventory of epiphytic orchids and hoya growing on host trees. The results showed there were 10 species of epiphytic orchid and 3 species of epiphytic Hoya, and 1 species of Dischidia growing on-location studies. The epiphytic orchids which found in location studies included Phalaenopsis amabilis, Aerides odorata, Cymbidium aloifolium, Dendrobium anosmum, Rhynchostylis retusa, Liparis condylobulbon, Taeniophyllum biocellatum, Cymbidium sp., Eria sp. Orchid species that most often found in the study location was Phalaenopsis amabilis . In addition, this study recorded Taeniophyllum biocellatum as an endemic orchid from Java that was found on this island. The epiphytic Hoya recorded in there, i.e. Hoya diversifolia, H. verticillata, and H. amoena , and also only found 1 species of Dischidia was Dischidia imbricata . There were 12 species of trees as the host trees of epiphytic, i.e. Irvingia malayana, Tectona grandis, Diospyros buxyfolius were the host trees frequently found as the host of the epiphytic plant. Zone 3 as an area of 1/3 basal part of a total length of the branches was the most preferred zone by epiphytic orchids and hoya. The epiphytic orchid and hoya hardly found in Zone 5.

Ethnobotanical uses of plants by Brangkuah Community of Moyo Island, West Nusa Tenggara, Indonesia

Abstract: An ethnobotanical study at Moyo Island, West Nusa Tenggara was carried out to record the traditional knowledge and utilization of plant species there. It is expected that traditional knowledge can play a role in natural resource management systems which can be used in conservation programs. This research was conducted with field observational methods in the Moyo forest and interviews with local people that have knowledge about utilization of plants. There are about 48 species of plants which are utilized by the Brangkuah Community in Moyo Island. Most of them are collected from the forest and 21% (10 species) are cultivated. Local people also use plants for medicine 41% (21 species), food 39% (20 species) and building materials 16% (8 species). The Brangkuah have started to cultivate several plants which are used as building material and food plants which previously collected from the forest. The Brangkuah community has conserved useful plants for their daily life. It is expected that the forest is sustainable. J Bangladesh Agril Univ 17(3): 325–337, 2019

The business case

Abstract: Central to the case for adopting some type of chip card in transit applications, whether it be a memory chip or true smart microprocessor card, are the benefits from more efficient fare and toll collection. The article presents a case for significant opportunities for contributions to the business case arising from co-resident applications compatible with transit use and for revenue generation additional to the payment of fares and tolls. Public transit fare collection and charges for road use, parking and other transportation applications provide the major opportunities for smart cards to replace complex and failure-prone cash-handling equipment and to avoid costly handling and security procedures. Some of the specific benefits to be gained from smart card use include: cost reduction, increased reliability; system cost reduction; and, data collection. The article also includes some application examples.

Biomass yield and carbon abatement potential of banana crops (Musa spp.) in Ecuador

Abstract: Banana is one of the most important agricultural products of Ecuador It relies on intensive monoculture cropping systems with a large volume of standing biomass and large amounts of residual biomass that can be used for carbon sequestration This study was performed (1) to quantify the yearly residual biomass generation, (2) to quantify the carbon stock of standing banana biomass, (3) to estimate the carbon sequestration potential by using the residual biomass generated yearly, and (4) to propose a biomass prediction model for banana crops in Ecuador The study was conducted between March 2018 and January 2019 in the three main banana-producing provinces of Ecuador (Los Rios, Guayas, and El Oro) Samples of rachis, pseudostem, leaves, and flowers from 36 banana plants of the variety Musa AAA Cavendish were taken for laboratory tests Physical measurements such as height, circumferences, number of leaves, and weights were determined for the 36 plants Results showed an average residue-to-product ratio of 379 and a country's yearly biomass generation of 265 Mt on a dry basis The carbon stock of the standing biomass was estimated as 418 ± 102 Mg/ha, 544 ± 096 Mg/ha, and 513 ± 111 Mg/ha for Los Rios, Guayas, and El Oro, respectively The estimated carbon abatement capacity of the residual biomass is 392 MtCO2/year Three biomass estimation models were developed in Python®, using the data collected in this study and least squares fitting for exponential models of the form: Y = AXn + C The models showed good prediction capacity for Ecuadorian banana plants, with R2 up to 085 It is expected that this study could serve as the basis for studies on developing sustainable conversion processes of banana residual biomass

Traditional Subsistence Farming of Smallholder Agroforestry Systems in Indonesia: A Review

Abstract: Agroforestry has been practiced for decades and is undoubtedly an important source of income for Indonesian households living near forests. However, there are still many cases of poverty among farmers due to a lack of ability to adopt advanced technology. This literature review aims to identify the characteristics and factors causing the occurrence of agricultural subsistence and analyze its implications for the level of farmer welfare and the regional forestry industry. The literature analysis conducted reveals that small land tenure, low literacy rates, and lack of forest maintenance are the main causes of the subsistence of small agroforestry farmers. Another reason is that subsistence-oriented agroforestry practices are considered a strong form of smallholder resilience. All of these limitations have implications for low land productivity and high-sawn timber waste from community forests. To reduce the subsistence level of farmers, government intervention is needed, especially in providing managerial assistance packages, capital assistance, and the marketing of forest products. Various agroforestry technologies are available but have not been implemented consistently by farmers. Therefore, it is necessary to develop an integrated collaboration between researchers, farmers, and regionally owned enterprises (BUMD) to increase access to technology and markets. Although it is still difficult to realize, forest services, such as upstream–downstream compensation and carbon capture, have the potential to increase farmer income.
