Abstract
Urbanization is a worldwide phenomenon which poses both opportunity and problem for urban areas. Potential for development becomes more significant as the population grows, especially in developing countries. Various perspectives see the phenomenon differently. Economists might see that this development is preferable, while environmentalists and medical people see it is more problematic than beneficial. This paper presents research-based documents and literature regarding urban development with its implication on the urban environment and humans’ health. It also suggested efforts to mitigate the impact of the inevitable urbanization, i.e., urban planting. Abundant scientific evidence confirms the benefits of urban planting to humans’ health and well-being. The virtues of urban vegetation resulted in the rise of concept for urban development that accommodates the existence of greeneries with all its attributes. Among the two most popular are the green networks and ecological network.

Abstract
Butini fish (Glossogobius matanensis) is one of the most endemic species of freshwater fish that lives in Matano Lake. The purpose of this study was to determine the histopathology of hepatopancreas and kidney from butini fish. The samples used were six Butini fishes with a size of approximately 18.5–20.5 cm. Organ preparations (hepatopancreas and kidneys) were fixed using 10% neutral buffered formalin (NBF), dehydrated using multilevel alcohol, embedded using paraffin, cut with a thickness of 5 μm, stained using Haematoxylin-Eosin (HE) then covered for microscopic observation. Data analysis used was qualitative descriptive. Measurement of metal content of Matano Lake water showed nickel content of <0.0184 mg/L, iron 0.0238 mg/L, zinc 0.0491 mg/L, and copper <0.0136 mg/L. Histopathological study on hepatopancreas showed fat degeneration and cell necrotic, while kidney showed renal tubular lysis, basal membrane detached, and cell necrotic. Thus, the high concentration of metal was thought to be related to the abnormal tissue of fish organs observed in this study.

Abstract
Edible bird nest (EBN) is an excellent export commodity from Indonesia and South East Asia countries. To keep the quality assurance of EBN, aflatoxin analysis should be conducted to check its biological hazard. This research was conducted to develop a rapid, sensitive and validated method to detect aflatoxin contamination in EBN. This study showed that in-house AF.2 IAC containing AF.2 monoclonal antibody can be used for EBN sample clean-up. Validation methods were measured using parameters which were recovery (86.5-96.3% for AFB1, 87.8-98.5% for AFB2, 82.8-100.5 for AFG1, 79.8-94.3% for AFG2), intra-day repeatability RSD (⩽ 6.4% for all aflatoxins), linearity (⩾ 0.99997 for all aflatoxins), limit of detection (0.26 ng/g for AFB1, 0.04 ng/g AFB2, 0.26 ng/g for AFG1, 0.03 ng/g for AFG2) and limit of quantification (0.79 ng/g for AFB1, 0.13 ng/g AFB2, 0.81 ng/g for AFG1, 0.09 ng/g for AFG2). These results showed that both recovery test of spiked PBS and recovery test of 3-level aflatoxin concentration spiked IBN were good, thus in-house AF.2 IAC can be used to analyze aflatoxins in EBN. Based on validation parameters such as recovery test, intra-day repeatability, linearity, LOD, and LOQ which had been tested, our method can be used for validated method for aflatoxin analysis in EBN. Further analysis of aflatoxins in edible bird nest will be reported separately.

Published: November 2019

Abstract
Local wisdom and local knowledge are very influential on the life of the Tobelo dalam community in the role of forest management and conservation, especially in the context of forest conservation in Aketajawe Lolobata National Park. We observed that there is a strong relationship within the community still rely on forest resources for subsistence, medicine, and livelihoods. We used observation and in-depth interview to describe the particular forms of local wisdom in forest management and its relation within forest conservation in Aketajawe Lolobata National Park. We particularly observe how the community interact with the particular management of Aketajawe block in the park, or local community in the Tayawi Village on managing their land-use system, the system of labor, and utilization of non-timber forest products in the context of making informal collaboration. The results showed that the existence of local wisdom on forest management is manifested by enforcing rules and sanctions. The belief system is inherently manifested through informal collaboration between the government and the Tobelo community. The involvement of the local community on the park’s tourism activities is also one example. They contribute as the local guides and play a role in the aspects of security and cleanliness of tourist activities.

Abstract
Plant rhizospheric zone is a narrow soil region were rich in microbes. Microbes are of capacity to dissolve phosphate. Phosphate (P) is the second essential component after N, which plays a crucial part in photosynthesis and root development. P is difficult to dissolve due to strong bonding with compounds in the soil. Here, we explored rhizospheric bacteria around chili peppers’ roots area. The bacteria were isolated and purified on solid media. The bacterial isolates were then quantitatively assayed for their capacity to dissolve phosphate using Pikovskaya liquid medium consisted of Ca3(PO4)2 as Phosphate source. Moreover, the capacity to produce Gibberellin hormone was also evaluated using Borrow et al. method. The assays revealed that phosphate concentration produced by rhizospheric bacteria of chili pepper ranged from 19.0 to 58.8 μg/L. Meanwhile, gibberellin concentration ranged from 5.81 - 12.79 μg/L. Our results present that bacteria inoculated from roots and roots area of chili pepper are potential as Plant Growth Promoting Bacteria.vThe first section in your paper.

Published: November 2019

Abstract
Floating Production Storage and Offloading (FPSO) is the mobile offshore structure like a ship where the wave load acts on the ship’s hull periodically. The influence of the cyclic load must be analyzed for the fatigue life of the FPSO. The objective of the present study is to analyze the fatigue life of the FPSO. Two models of FPSO are taken to be analyzed. To calculate fatigue life, JONSWAP wave spectrum is adopted. Then, calculate the Response Amplitude Operator (RAO) to obtain the stress response of the spectra. Based on the stress response spectra calculation, the zero and second moment may be determined using Simpson’s rule. The stress cycle can also be obtained and the failure cycle is determined from the S-N curve. From the S-N curve, the X parameter is used for the main parameter. According to this, the fatigue life of FPSO can be obtained.

Published: November 2019

Abstract
This study aims to assess the role of CTI-CFF in handling marine ecosystem problems that include coral reef conservation, fisheries, and food security in Indonesia. To achieve the objective, the research method used is a qualitative study using library research data collection techniques. The result of this study indicates that the role of CTI-CFF in environmental conservation in Indonesia can be divided into three aspects of CFF itself namely on coral reefs, fisheries and food security. A number of conservation efforts have been carried out with the implementation of national action plan and have significant impacts on the sustainability of society and the environment. On coral reefs issues, CTI-CFF runs particular programs namely CTI-COREMAP and Marine Protected Areas (MPA). On fisheries issues, CTI-CFF has a particular program called Ecosystem Approach to Fisheries Management (EAFM). CTI-CFF in Indonesia plays an important role in implementing the strategic steps of the regional action plan which is later adopted into the national plan of actions. These plans are used as a parameter of the involvement of the CTI-CFF in efforts to save marine ecosystems in Indonesia.

Published: November 2019

Abstract
This article aims to explain how to apply the approach to action and consequences with a progressive contextual explanation mode in the study of marine fisheries resource use practices in fishing communities. This approach is part of an effort to develop a critical study of human ecology. The approach with an explanation mode would like to explain empirically and progressively the patterns of fishing practices and the environmental and resource consequences of marine fisheries caused (positive, negative) in the context of their internal and external and historical socio-cultural influences. The approach with explanation mode rejects assumptions from various perspectives of previous anthropological theories which tend to be ideal, essentialist, general and abstract, totalist, and a priori, which are not or less able to see the phenomenon of variation, the role of individuals and parts, processes, openness system, change, temporal and context. Through the application of the approaches and explanatory modes, the complexity of the practices of the various fishing categories of Pulau Sembilan (Sinjai) which are used as illustrations can be understood empirically, contextually, and holistically as they are.
