Optimization of Local Commodity Distribution System: Case Study Seaweed Distribution from Kalimantan to Makassar

The existence of Presidential Regulation Number 33/2019 concerning the Roadmap for the Development of the National Seaweed Industry indicates that it is time for Indonesia to be more serious in developing the seaweed resource industry to meet domestic and international demands. In line with the volume of seaweed traffic in Indonesia of 36.942 tons per year, as well as the production capacity of Indonesian seaweed which controls more than 70% of the global seaweed market, this situation will have a very good impact on seaweed farmers to continue production of seaweed. However, behind the enormous amount of demands for seaweed, there are serious problems experienced by seaweed farmers, especially for seaweed farmers in Borneo. Majority of seaweed produced in Kalimantan cannot be distributed properly to importing areas due to the lack of seaweed transportation. This paper evaluates the current distribution system to find suitable payload for planning a new distribution system by operating either a non-propelled or a self-propelled barge. The non propelled barge will be operated by chartering a tugboat (time charter). Therefore, the manning cost and capital cost for tugboat construction will be the owner’s responsibility. Every options are calculated to find feasible dimension. Unit cost that may be charged to consumers also calculated to provide the comparison with the current unit cost paid by seaweed farmers at Rp 550.000/ton. Unit cost calculation result for the 1st option (Non-propelled barge) is at Rp 367.200/ton and for the 2nd option (Self-propelled barge) is at Rp 870.100/ton. Therefore, the most optimum solution is a non-propelled barge, around 27% cheaper than the current unit cost charged.

ANALISA PENCEMARAN LAUT OLEH PTT EXPLORATION AND PRODUCTION (PTTEP) AUSTRALASIA TERHADAP LAUT TIMOR INDONESIA

<p><em>This study aims to analyze a blowout from an oil and gas leak owned by PTT Exploration and Production (PTTEP) Australasia in the Montara oil field in the Indonesian Timor Sea, and how to resolve disputes between Australia and Indonesia. A qualitative approach was used in this study, whilst the data collection technique was through library research. The theory of state responsibility, the concept of human security, and the concept of international maritime law are used to analyze disputes between Indonesia and Australia. The study found that the Montara oil spill had not only damaged the marine ecosystem but also polluted Indonesian waters. It also found that although the Australian government had formed a special commission to resolve cases and even used dispersant, it had not satisfied all parties. Several points are summarized. First, the Montara oil spill in Australia is a transnational study because the impact has crossed national borders. Secondly, UNCLOS has a weakness in the settlement of the Montara case because the Convention only provides a description related to ‘Responsibility of Each Country’ and does not specifically arrange material compensation mechanisms to countries that cause sea pollution. Third, the Montara oil spill has caused huge losses for Indonesian seaweed farmers, especially 13 districts in NTT. The recommendations are that the Indonesian government along with the Montara Victim Peoples’ Advocacy Team should continue to follow up the case of oil spills from the Montara platform and continue to fight for compensation to the Australian government and the PTTEP as the responsible party.</em></p>

Genetic Diversity Analysis of Cultivated Kappaphycus in Indonesian Seaweed Farms using COI Gene

Indonesia is a major player in the aquaculture of red algae, especially carrageenan producing ‘eucheumatoids’ such as Kappaphycus and Eucheuma. However, many current trade names do not reflect the evolutionary species and updated taxonomy, this is especially the case for eucheumatoid seaweeds that are highly variable in morphology and pigmentation. Genetic variation is also not known for the cultivated eucheumatoids in Indonesia. Therefore, this study aimed to determine the species and the level of genetic variation within species of cultivated eucheumatoids from various farms across Indonesia, spanning 150-1500 km, using the DNA barcoding method. Samples of seaweed were randomly collected at 14 farmed locations between April 2017 and May 2018. For this study the 5-prime end (~ 600 bp) of the mitochondrial-encoded cytochrome oxidase subunit one (COI) was amplified and sequenced. Morphological examination showed that the samples were quite variable in branching pattern and color. All samples collected from farms with floating line cultivation were identified based on COI sequences as Kappaphycus alvarezii and showed no variation in the COI gene. One farm sample with bottom-line cultivation was identified as K. striatus. The low genetic variation is in contrast to the phenotypic variation of samples, indicating that variation and phenotypic responses to environments is still found in samples with implications for growth rates and carrageenan yield and quality. Information about the genetic variation in stocks is important base knowledge for maintaining, expanding and continuing seaweed aquaculture.

An analysis of the current status and future of biosecurity frameworks for the Indonesian seaweed industry

Indonesia is the world largest producer of the red seaweeds Kappaphycus and Eucheuma; however, this country is facing significant challenges such as disease outbreaks, epiphyte infestations and a loss in seedling quality. Biosecurity practices have been widely adopted in other aquaculture sectors and when enforced can help to limit the introduction and spread of diseases and pests. To assess current capacity for biosecurity in seaweed aquaculture in Indonesia, a systematic analysis of policy frameworks including legislation, regulatory tools, and national standards was conducted. Biosecurity themes and risks were used to evaluate current national biosecurity content. The results identified major challenges faced by the industry in order to implement biosecurity policies in practice. Barriers to implementation included unspecific reference to the seaweed aquaculture sector, limited variety of approaches to biosecurity, limited use of up-to-date scientific evidence, insufficient guidance for the use of precaution and insufficient inclusion of specific biosecurity hazards. In general, although national regulations are currently under revision, current policies indicate a lack of clarity where biosecurity is included. Six recommendations are suggested to incorporate proactive biosecurity actions into current frameworks, with the aim of improving the health and sustainability of the seaweed aquaculture sector in Indonesia.

Analisis dan Strategi Untuk Mendukung Prospek Perdagangan Rumput Laut Indonesia

The Indonesian seaweed trade is still dominated by dry seaweed, even though Indonesia's seaweed still has high prospects for development. The purpose of this study is to analyze and provide strategies for supporting the prospects of Indonesia's seaweed trade. In achieving this goal, we use qualitative desk study methods and SWOT analysis. The results showed that Indonesia's seaweed trade still shows the opportunity to increase high added value by prioritizing the trade of semi-finished products rather than dried seaweed. This is supported by the strength of Indonesian seaweed which has a large potential for cultivation, a high number of laborer, high consumption of domestic and foreign seaweed derivative products and the availability of sufficient technology and expertise. Those strengths used to seize high import market opportunities. The existence of a national seaweed development road map also helps create a better prospect for seaweed trade.

Seasonal variation in growth and carrageenan yield of Kappaphycus alvarezii (Doty) Doty farmed using mass selection in Bungin Permai Coastal Waters, South Konawe District, Southeast (SE) Sulawesi, Indonesia

Two methods, tissue culture, and mass selection are generally used to improve the quality of the seedlings of the red algae K. alvarezii. Mass selection is relatively new to be adapted to the Indonesian seaweed farming. In this study we attempted to cultivate the seaweed for 10 months (February-November 2013) in Bungin Permai coastal waters, South Konawe, Indonesia. Cultivation was performed for 30 days of each cycle, using long-line method. Each rope contained had distance between clumps of 15-, 20-, 25- and 30-cm. The selection was carried out until 9th generation. The results showed that the daily growth rates (DGRs) among treatments were found to vary and tended to have seasonal variation. Minimum DGRs occurred in October while the maximum was in April/May. The DGRs range was from 3.81±1.80%/day to 8.32±1.12%/day while mean annual DGRs of 15-, 20-, 25- and 30- cm PD were 6.46±1.98, 6.62±2.00, 6.74±2.01, and 6.90±2.03%/day, respectively. No significant differences was found among four different planting distance. The mean carrageenan (semi-refined carrageenan/SRC) yields were varied among treatments and tended also to have seasonal variation. Minimum SRC of all treatments was varied and occurred in March/June while the maximum SRC were in May/October/November. The carrageenan yields range were from 31.53±2.04% to 48.91±5.05%. The highest mean annual SRC was recorded for 15-cm planting distance (PD) (42.02 ± 3.38%) followed by 30-cm PD (41.58 ± 2.95%), 20-cm PD (41.56 ± 6.03%) and 25-cm PD (41.45 ± 4.09%). The quality of cultivars produced from the selection met international specifications suggesting that mass selection for longer period could be ‘a new method” to produce better quality of seedlings.

Effect of drying techniques on color and bioactive potential of two commercial edible Indonesian seaweed cultivars

Seaweeds (Kappaphycus alvarezii and Sargassum duplicatum) are potentially rich sources of bioactive compounds and functional constituents that are used in food applications. Sun, oven, vacuum, and freeze-drying techniques are commonly used seaweed drying techniques and could be classified as cheap (sun and oven) and expensive (vacuum and freeze) drying techniques based on ovens’ market price. Therefore, the study was designed to investigate the effect of cheap (sun and oven) and expensive (vacuum and freeze) drying techniques based on color and antioxidant potential of K. alvarezii and S. duplicatum using phenolic and antioxidant assays. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) were employed to discriminate the drying techniques by instrumental color analysis. The results revealed that oven-dried seaweed extracts exhibited higher levels of phenolic (0.30 to 0.36 mg GAE g−1) and antioxidant potential (3.59 to 79.68%). PCA and HCA discriminated the drying techniques into two well-defined groups/clusters I (oven, vacuum, and freeze-drying) and II (sun drying) and revealed higher ΔE values of sun-dried seaweed samples, which was interpreted as color was preserved using drying techniques of cluster I. Overall, oven, vacuum, and freeze-drying techniques reported similarities in color characteristics and could be an alternate drying technique to preserve the color of seaweed cultivars. Therefore, oven drying technique is recommended due to low cost (compared with vacuum and freeze-drying) and an affordable alternative to sun drying, the preferred technique in fishing communities of low-and-middle-income countries, for the development of seaweed-enriched functional foods.

Trade Liberalization and Export Competitiveness: A Case Study on Indonesian Seaweed In the Global Market

This research aims to analyze the characteristics of Indonesian seaweed commodities, analyze Indonesian seaweed export competitiveness model in the global market, analyze the Government of Indonesia's efforts to improve the export competitiveness of Indonesian seaweed commodities and analyze the role of actors in increasing the Indonesian seaweed in the global market. This research used mix method analysis quantitative and qualitative, the collected data through primary data derived from Indonesian Seaweed Association and secondary data from United Nations Commodity and Trade, Indonesian Central Bureau of Statistic, Bank of Indonesia, Ministry of Trade. This research found that the characteristics of Indonesian seaweed according to several variables such as export competitiveness, productivity, raw material price, trade liberalization rate, inflation rate, exchange rate, research and investment development, and product differentiation have fluctuated value from 2006 to 2016. The result of regression data shows that interest rate, exchange rate, economic growth, raw material price, farmer wage rate, product differentiation, and liberalization policy has a positive effect on RCA seaweed. Inflation, productivity, nominal protection coefficient, and research development investment have a negative influence on RCA. The prediction on the competitiveness of Indonesian seaweed is that the competitiveness will still increase, but it depends on the economic condition of Indonesia in the future. It is necessary to have synergy between government, private, and universities to increase seaweed competitiveness in the global market.

Ranking of Seaweed Agro-Industry in Indonesia Using Fuzzy OWA Method

Seaweed has an important role in efforts to increase Indonesia’s fisheries production capacity because seaweed is one of the three main commodities of the fisheries revitalization program which is expected to improve community welfare. At 2016, Indonesian seaweed production had reached 11 million tons and has to increase in the coming year.Indonesia is one of the largest producers of Euchema and Gracilaria, and dominate 50% of market share in the world.Nowadays, 80% of the exported products are still in the form of raw material (dried seaweed). Therefore, the government plans to reduce the export of seaweed in the form of raw materials and process it into several potential commodities. To rank the most potential commodities, this study uses the Non-Numeric Fuzzy method and the OWA Method. The results indicate that there is a lack of development from the seaweed agro-industry in Indonesia, while the demand for processed products is high. From the three alternatives of the processed products, SRC was the first product to develop with a weight of 0.5436 and the lowest value.

Application of chemometric techniques: An innovative approach to discriminate two seaweed cultivars by physico-functional properties

Chemometric techniques were employed to discriminate two Indonesian seaweed cultivars (Kappaphycus alvarezii and Sargassum duplicatum) based on their physico-functional properties. Data of physico-functional properties, including emulsifying activity and bulk density, were processed using multivariate, discriminant analysis (DA), principal component analysis (PCA), and cluster analysis (CA). Significant differences (p < 0.05) and discrimination (multivariate analysis (F9,14 = 57.85; Wilks’s lambda = 0.02, p < 0.0001)) were determined among physico-functional properties of seaweed powders. In addition, DA method clarified (Λ = 0.02 and χ2 = 63.74) variations between samples along with two discriminate functions. Moreover, PCA (49.63% with Eigenvalues > 1) and CA (clusters 1 and 2) methods confirmed that the seaweed samples possessed differing physico-functional properties, which implied their distinctive use in food product development. Overall, our results demonstrated strong variation in seaweed powers using chemometrics, which might contribute to the rapid applicability of chemometrics in evaluating novel food material.

Analysis of Internal Risk Management in Indonesian Seaweed Farming

This study aims to identify the internal risk management and acknowledge the highest and the lowest risk that have significant impact on seaweed farming in Indonesia. The case study is used in Morowali-the central seaweed farming in Indonesia. The data obtained from primary data and secondary data and used a census through interview and questionnaire. Data analysis apply analytic hierarchy process (AHP) to determine the weight of each criterion and sub criteria. The results show that the internal risks of seaweed operation by Indonesian farmers include the quality of seeds, technology, human resources, capital and cost management. The study found that the highest internal risk of seaweed operation on the farmers level is technology. This study provides insight and information to the seaweed farmers and manager of seaweed industry about the typical of internal risks in the farmers level.

Significance of Experience, Farm Size, Quantity of Propagules and Location f or Seaweed Farmers in the Divided Island of Sebatik

Seaweed-Kappaphycus-Euchema Cottonii and Denticulum species was first cultivated at Sabah side of Sebatik in 2009. By November 2014, sixty one Sabahan seaweed farmers cultivated 122 ha or 3,050 long lines. Thirty Sabahan seaweed farmers in Kampung Pendekar (3.2 m.t dried) and 31 in Burst Point (12.5 m.t dried) produced 16 metric tonnes of dried seaweed contributed 31% to Tawau’s total production (51 m.t). The remaining 69% were from farmers in Cowie Bay that separates Sebatik from municipality of Tawau. Indonesian in Desa Setabu, Sebatik started in 2008. However, the number of Indonesian seaweed farmers, their cultivated areas and production (as well as quality) in Sebatik increased many times higher and faster than the Sabah side of Sebatik. In 2009 more than 1,401 households in Kabupaten Nunukan (including Sebatik) cultivated over 700 ha and have produced 55,098.95 and 116, 73 m.t dried seaweed in 2010 and 2011 respectively. There is a divergence in productions from farming the sea off the same island under similar weather conditions. Which of the eight explanatory factors were affecting production of seaweeds in Sebatik? Using Cobb Douglas production function, Multiple Regression analysis was conducted on 100 samples (50 Sabahan and 50 Indonesian). Results; Variable significant at α = 0.05% are Experience in farming whereas Farm size; Quantity of propagules and Location — Dummy are the variables significant at α 0.01%. Not significant are variables Fuel; Age; Number of family members involved in farming and Education level.

Managing risks in the Indonesian seaweed supply chain

Seaweed supply chains in Indonesia, especially carrageenan and agar products, are subject to risks arising both inside the participating companies and in their external networks. Uncertainties in yield, quality, price, and infrastructure in one part of the supply chain can affect the whole chain. To ensure a sustainable seaweed industry, an appropriate supply chain risk management (SCRM) is needed. There are four critical steps in SCRM: identifying seaweed supply chains, identifying and categorizing risks, assessing risks, and mitigating risks. To identify seaweed supply chains, we conducted field research, in-depth interviews, and literature studies. The field survey was conducted in the Provinces of South Sulawesi, West Java, East Java, Banten, and West Nusa Tenggara. The seaweed supply chains were modeled by the software Umberto to get a better understanding of material and energy flows between the key members. To identify and categorize the risks, we started with the risks mentioned in the existing literature works, and then applied the Delphi method to analyze the potential risk sources, their causes, and their impacts. To assess risks, we used a semiquantitative approach through the face-to-face interviews to generate a risk map showing the likelihood, and impact of adverse events. Afterward, the risk intensity was categorized based on the value of the responses and classified into five categories: negligible, marginal, critical, most critical, and catastrophic risks. The mitigation strategies considered sustainability (environment, economy, and social) and risks criteria. Multi-criteria decision analysis was used to evaluate these strategies.

Expertise: Sometimes blinding and costly

Economics![Figure][1] Underwater Indonesian seaweed farmer. PHOTO: STINATANO/WIKIMEDIA COMMONS Experts trying to solve global challenges often call for new technologies and access to information, but they might do better to take a harder look at what they've been doing all along, to see whether they've missed some simple solution that could make a dramatic difference. Building on literature in economics and learning sciences, Hanna et al. studied Indonesian seaweed farmers and found that, despite years of experience that showed the importance of factors such as the spacing of pods during planting, the farmers hadn't noticed that adjusting pod size might be useful as well. This work may help improve the way technologies and training are deployed, in agriculture and beyond.

Including capabilities of local actors in regional economic development: Empirical results of local seaweed industries in Sulawesi

Stimson, et al. (2009) developed one of the most relevant and well known model for Regional Economic Development. This model covers the most important factors related to economic development question. However, this model excludes the social components of development. Local community should be included in terms of the development of a region. This paper introduced to the Stimson model “Skills” and “Knowledge” at the individual level for local actors indicating the capabilities at the individual level and introduced “Human Coordination” for the capabilities at the collective level. In our empirical research we looked at the Indonesian seaweed market with a specific focus on the region of Baubau. This region was chosen because there are hardly any economic developments. Furthermore this study focuses on the poorer community who are trying to improve their situation by the cultivation of Seaweed. Eighteen local informants was interviewed besides additional interviews of informants from educational and governmental institutions in the cities of Jakarta, Bandung and Yogyakarta. The informants selected had a direct or indirect relationship with the region of Baubau. With the support of the empirical data from this region we can confirm that it is worthwhile to include the local community in the model for regional economic development. The newly added variables: at the individual level; Skills and Knowledge and at the level of the collective: Human Coordination was supported by the empirical material. It is an indication that including the new variables can give regional economic an extra dimension. In this way we think that it becomes more explicit that “endogenous” means that the people, or variables closely related to them, should be more explicitly included in models trying to capture Regional Economic Development or rephrased as Local Economic Development Keywords: Regional and endogenous development; Fisheries and seaweed industries; Indonesia; Sulawesi; Community-based management, Local community.
