Published: September 2020

Abstract
This paper examines the impact of foot and mouth disease (FMD) outbreaks on meat prices in Malaysia (i.e., at wholesale and retail of beef, imported mutton and mutton) from January 2000 to December 2015. The data were analyzed using time series methods (i.e. unit root test and error correction model). The results demonstrate that frequent FMD outbreaks have significant impacts on meat prices in Malaysia. Most of the drops in prices occurred within a short period of time. Due to FMD outbreaks, several meat price margins took a long time to recover, while some price margins improved quickly. This may occur due to the FMD reduces the amount of meat that an animal can produce, and animals affected by this disease require some time to recover. High demand with low supply will consequently cause an increase in the price of meat.
Agricultural Land Conversion Mechanisms, Internal Migrations, and Housing Policy: Case Studies of Industrial Estates in the Northern Cikarang, West Java Province, Indonesia
Authors: Irawati Miya 
Published: September 2020

Abstract
Various researches on agricultural land conversions stepped into the conclusion that those conversions, into housing and industrial land uses, were difficult to be controlled. Housing and industrial functions dominated those conversions on 36% and 20% respectively in the Province of West Java while they correspondingly accounted for 57% and 22% in the Java island. Other notable features of that conversions consisted of the proximity to the economic centers and occurred in rural areas that were located in urbanized regions. This paper identified that land-use change mechanisms have been including internal migrations within their dynamics in which, on the contrary, the supply for migrants’ accommodations has not been appropriately considered as the evidence-based information into the development policy. Cikarang, a prominent District of industrial estates in the Province of West Java, reflected the Central and Local Governments’ underdeveloped capacity in terms of incorporating the mechanism, data and integrating multi-sectoral programs through housing policy. Through random sampling, migrants’ origins in both areas altogether can be figured out as follows: Bogor/Bekasi (2%), DKI Jakarta (2%), West Java (35%), Central Java/D.I. Yogyakarta (41%), East Java (6%), Outside Java Island (11%). The growing internal migrations which accompanied the increasing demand for accommodations were inadequately responded to. While considerable percentage of migrant samples (46-92% in Northern Cikarang) were found to be financially capable for paying monthly rent above the standard costs of public rental housing (Rusunawa) however the housing policy was unable to innovatively design the rental systems which expanded its benefits towards various groups of lower-income and sustain its operational costs. This paper concluded that housing policy, particularly Rusunawa, would be the key where the agricultural land conversions rate can be moderated, and the internal migrations may turn into capital.

Abstract
Mount Gede Pangrango National Park is the example of a protected area in which land conflict happens. The surrounding communities run their cultivation activities inside the national park which are actually illegal according to the law. This research aims to capture the progress of conservation efforts vis-a-vis such an encroachment issue as well as to explore the characteristics of the surrounding villages that can explain the encroachment level. To this end, this research performed spatial analysis and stepwise multiple regression using Landsat imagery, Google Earth images and village potential data. The result shows that the area of plantation, dry-agriculture land and bare land were declining. The encroachment level could be associated with the distance of settlement to the number of farm laborers around and the land slope of the national park. Meanwhile, the existence of large land occupied by the private company could restrain the tendency of local people to encroach the land of national park.

Abstract
Java is widely known as the economic center of as well as the most populous (main) island in Indonesia. Rapid urbanization process and economic development in Java are mostly concentrated in six major metropolitan areas (MA): “Jabodetabek” (Jakarta MA), “Bandung Raya” (Bandung MA), “Kedungsempur” (Semarang MA), “Kartamantul” (Jogjakarta MA), “Gerbangkertosusila” (Surabaya MA), and “Solo Raya” (Surakarta MA). Due to its extensive development progress over the past decades, Java is now facing environmental crisis and declining carrying capacity. This paper aims to measure urban and regional sustainability in these metropolitan areas in particular and in all regencies/municipalities in Java more generally by drawing on the so-called Regional Sustainability Index (RSI). The results show that every regency/municipality in Java has diverse regional development condition and sustainability performance. In addition to this, most of the localities (regencies/municipalities) being part of the metropolitan areas have a relatively better economic, social, and environmental condition than that of other localities.

Published: September 2020

Abstract
Sustainable city development is influenced by the availability of sustainable infrastructure. High population growth in urban areas requires improvements in many aspects, especially infrastructure. However, the need for improvements is often not fulfilled. As a result, various problems that would ultimately affect the city sustainability emerge. To overcome the problems, it is important to develop comprehensive and integrated policies and strategies framework that enables a city to meet the demand for improvement and sustainability. The very first stage of developing a city development framework is to understand the current condition of city performance and sustainability. The main objective of this paper is to develop an indicator framework of a sustainable city. The stages of developing the framework consist (1) defining the criteria and indicators of sustainable city; (2) measuring performance and sustainability level of a city and (3) identifying the influential indicators that increase the city sustainability status. The criteria of sustainability framework were developed based on the Triple Bottom Line (TBL) Sustainability of people, planet, and profit. Subsequently, the level of sustainability is measured by using a weighted-score method. This paper presented the results of the performance and sustainability assessment of two cities in the Lampung Province (Bandar Lampung and Metro City) based on the performance and sustainability framework developed in this study. It can be concluded that Bandar Lampung City is less sustainable than Metro.

AbstractBlackeye thicklip wrasseHemigymnus melapterusis a Labridae that was widespread throughout the tropical and subtropical waters of Indo-Pacific. In eastern Indonesia, blackeye thicklip wrasse found from the Strait of Bali, Mentawai Islands, Raja Ampat Islands, Manado and surrounding areas, and Banggai; while in central Indonesia, blackeye thicklip wrasse found in the waters of the Spermonde Archipelago. This research aims to analyze the sex ratio, gonad maturity stage, and the size at first maturity of blackeye thicklip wrasse in the Spermonde Archipelago. This research was done on the population of blackeye thicklip wrasse in the Spermonde Archipelago, South Sulawesi, Indonesia. Samples were collected from fishermen caught landed in the Rajawali Makassar Fisheries Port at Makassar City. Blackeye thicklip wrasse sex ratio was not balanced. This imbalance was thought to have something to do with the “r” reproductive strategy where blackeye thicklip wrasse tries to produce as many eggs as possible to maintain its population. The success of this strategy probably supported by protogyny reproduction patterns where young fish can produce eggs as fast and as much as possible before being devoured by predators. Based on its gonad structure, blackeye thicklip wrasse could be classified as fish with a total spawning pattern that take place long spawning period or individual different spawning period throughout the year. The size at the first maturity of blackeye thicklip wrasse female was 21.4 cm; it was much smaller than half the size that has ever been caught.

Abstract
Overfishing in the Spermonde Archipelago has resulted in long-term changes in fishery composition and structure, as well as in resource utilization patterns. Later on, the patterns of resource use are highly variable, with new activities and new target species, e.g., ornamental corals and intensive coral reef fishery being a relatively recent phenomenon in the area. This research aims at measuring the coral fishes abundance and assemblages in six islands (Kapoposang, Lanyukang, Lumu-Lumu, Badi, Ballang Lompo, and Karanrang), representing off-shore and in-shore of Spermonde Archipelago waters during the occurrence of the 2016 El Nino. Underwater Visual Census (UVC) method was done to measure coral fish abundance, once every seasonal interval, totaling four times for every island, on 70 meter transects covering an area of 350 m2 (2.5 m to the right and left and 5 m above). Fish species found were identified by following several coral fish identification books Data was analyzed for their total species abundance based on the family. Results showed that coral fish abundance by the family was found to be lowest (less than 10.000 individuals/hectare) all through the year in Karanrang Island. The most abundance was found in Lanyukang Island (84.600 individu/hectare) during the month of September, followed by Badi Island (59.971 individu/hectare). In February, fish abundance of 35. 743 and 46.886 individu/hectare were only found in Kapoposang and Badi islands. All in all, on average, Badi island showed for having relatively equal coral fish abundance in all four seasons. One hundred species were found in Lanyukang, while 78 species were found in Lumu-Lumu, totaling 136 species of coral fishes of 28 families. Coral fishes species always found in all trips were 20 species in Lanyukang and 11 species in Lumu-Lumu. Four species always found in both islands were Thalassoma hardwicke, Neoglyphidodon nigroris, Labroides dimidiatus, Cirrhilabrus ryukyuensis. Fishes found most abundance were from Labridae and Pomacentridae families, each of 31 and 30 species. The temporary conclusion was that Lanyukang has more species than Lumu-Lumu.
Seagrass meadows for fisheries in Indonesia: a preliminary study
Authors: Ambo-Rappe R 
Published: September 2020

AbstractSeagrass meadows are among the most productive ecosystems on earth and are of great importance to support an abundance and diverse fish assemblages that form the basis for artisanal fisheries, especially in the tropics. Fisheries are vital in maintaining food security, and therefore the ecosystems that support these fisheries are also essential. Seagrass ecosystems contribute to fishery productivity, and seagrass fisheries are especially common in the Indo-Pacific region, where seagrass beds and their associated fauna are heavily exploited. However, these fisheries remain largely undocumented. Within the Indo-Pacific region, Indonesia contributes significantly to seagrass biodiversity and global seagrass extent. Seagrass fisheries undoubtedly exist in Indonesia, but publications on this topic are rare. Therefore, there is a need to highlight the extent, importance, and status of fisheries exploitation in the seagrass meadows of Indonesia. The aims of this study were to determine the importance of seagrass meadows in supporting fisheries productivity and examining the variability of seagrass fisheries in Indonesia. A literature search of published data on fisheries activities in seagrass meadows in Indonesia was conducted from March-May 2020. Google Scholar database was searched using the most specific keywords in English and Indonesian, for example, “seagrass” AND ”fisheries” AND ”Indonesia”, “seagrass fisheries” AND ”Indonesia”, “Perikanan Skala Kecil” DAN “Padang Lamun”, in the title, abstract or keywords, in order to obtain information from the few papers on seagrass fisheries in Indonesia published in English (international journals) and Indonesian. Additional data on seagrass fisheries and the fishing methods/gears used were collected by interviewing people who live or work in areas with few or no published data to gain a broader picture of seagrass fisheries in Indonesia. It was found that seagrass fisheries occur in almost all nearshore seagrass areas in Indonesia, including around many small islands. Many fishing gears are used in these fisheries, the most common being gill nets, traps, and gleaning (directly picking up fauna from the seagrass beds using bare hands or very simple tools). Therefore, from a socioeconomic perspective, seagrass beds are extremely important for the livelihoods of coastal and island communities in Indonesia.
Microhabitat preference of the Banggai Cardinalfish (Pterapogon kauderni): a behavioural experimental approach

Published: September 2020

Abstract
The Banggai cardinalfish Pterapogon kauderni is an endangered endemic species with an exceptionally small native distribution and an unusual life history. A paternal mouthbrooder with direct development, symbiosis with benthic organisms (referred to as microhabitat), is crucial to its survival. This is especially so for postflexion larvae (recruits), after their release from the male parent’s buccal cavity. Microhabitat preference in P. kauderni has been studied empirically based on a survey of wild populations. This study adopted an ex-situ experimental approach to P. kauderni microhabitat preference using two well established behavioural trial methods: choice flume and choice tank. The experimental animals were sourced from the introduced P. kauderni population in Palu Bay, Central Sulawesi, Indonesia. The choice flume method was applied at the Central Sulawesi Marine and Fisheries Service Hatchery in Mamboro, Palu, with microhabitats Diadema setosum and D. savignyi. The choice box method was applied at the Universitas Hasanuddin Centre for Research and Development in Makassar, South Sulawesi, Indonesia, with microhabitats Heteractis crispa, Entacmaea quadricolor, D. savignyi and D. setosum. The results indicate the most to least preferred preference hierarchy of D. savignyi, D. setosum, H. crispa, E. quadricolor. While the preference for the sea anemone H. crispa compared to E. quadricolor is consonant with empirical in situ studies on P. kauderni, the observed preference for D. savignyi over D. setosum was unexpected, and points to the need for further research. Observations made during the trials also raise the possibility that imprinting may occur and influence subsequent microhabitat preference.

Abstract
Maninjau Lake is located in Tanjung Raya Subdistrict, Agam Regency, West Sumatra Province, with the surface area 9,737.50 ha. Maninjau Lake has one major outlet through the Batang Antokan river flows to the west coast of Sumatra Island. The excessive number of floating net cages, those are upper of carrying capacity, is the biggest problem in Maninjau Lake. Mass fish kills happened frequently due to deterioration of water quality in this lake. This study is aimed to observe the current fishery activities and environmental conditions in Maninjau Lake. The data were collected by survey using interview methods and record statistic data from the government. The results showed that Maninjau Lake has three functions as ecologies, social and economic. The capture fisheries are still using the traditional fishing gears, while the fish culture is using the floating net cages. There were 18 species inhabited in Maninjau Lake, consists of native and introduced species. Moreover, invasive species have been found, namely Pterygolichtys pardalis (Amazon sailfin catfish) and Amphilophus trimaculatus (flowerhorn). Nowadays, it is difficult to catch the native fish, Tor sp (gariang), and the endemic fish, Psilopsis sp (rinuak). Maninjau Lake is in the eutrophic state with quite good waters conditions, but it could become worse since the lake is steadily changing naturally and also anthropogenic activity. The fisheries management in Maninjau Lake should involve the stakeholder groups that have a different degree of interest, the role of management, and related institutions.

Abstract
Zooxantellae is living symbionts in the body of giant clams. This research was conducted to determine the sensitivity of the loss of zooxanthellae (bleaching) from the body of giant clam as a tool to detect metal pollutants. Juvenile of giant clam was exposed to lead in concentrations of 0, 0.004, 0.008, 0.016, 0.032 mg/l for 24 hours. Zooxanthellae density data were analyzed with parametric anova. The zooxanthellae densities at treatments 0, 0.004, 0.008.0.016 and 0.032 mg / respectively were 32,322,222.2, 32,488,888.89, 24,977,777.78, 17,676,666.67, and 14,542,222.22 cell/g mantle. Statistical analysis showed that there were significant differences in zooxanthellae densities of control with 0.016 and 0.032 mg/l treatments. There was no mortality of the juvenile of giant clams during the experiment. Therefore, it was concluded that the loss of zooxanthellae from giant clam’s body could be used as a sensitive biomarker to detect lead metal toxicity. Zooxanthella of Tridcana derasa is also considered as a sentinel organism that is potential for ecotoxicological studies.
