Abstract
Mountain communities in Mutis commonly work as farmers, and farm is used as physical capital to provide all life necessities such as food, housing, clothing, and services. Fulfillment of their life necessities depends heavily on income generated from agriculture, farming, forestry, animal husbandry, and other small business products. This research aims to understand the level of welfare of mountain communities applying the traditional agroforestry model in Ajaobaki Village, District of South-Central Timor. The study was conducted from May to July 2021, with the number of respondents being 41 households. The method used in this research was survey methods with descriptive analysis. Community welfare is measured through respondents’ expenditures for one year (2020) to meet the needs of food, housing, and clothing compared to expenditures to meet the needs/consumption of services such as education, health, electronic goods, recreation, and so on. The result of the research showed that the value of consumption of the basic necessities per year to meet comunities’ needs for food was IDR 9,352,902.439 on average, the board was IDR 1,696,341.463 on average, and clothing was IDR 783,902.439 on average. Meanwhile the average expenditure for service consumption per year was IDR 9,916,439.024. Analysis of the level of community welfare through the analysis of the good services ratio (GSR) in Ajaobaki Village showed that the percentage of people who are not prosperous are 56.11%, prosperous 29.26%, and more prosperous 14.63%. The people who are not or less prosperous generally prioritize primary needs such as food, housing, and clothing rather than consumption of service values, while prosperous people are oriented towards the value of consumption of services (services) in the form of education, health, communication, social, and so on.

Abstract
The Covid-19 Pandemic in Indonesia has an impact to agriculture and extension activities. Agricultural extension activities during the Covid-19 pandemic were carried out used online media such as Whatsapp Groups, Youtube and radio, whereas extension activities involving many people were temporarily removed. Agricultural extension agents are agents of change related with farmers. So that, it is important for farmers to evaluate the performance of agricultural extension workers during the Covid-19 pandemic, so that the benefits of extension activities can feel by all farmers. The purpose of this study was to analyze the perceptions and factors that influence farmers’ perceptions to the performance of Field Agricultural Extension during the Covid-19 pandemic in Jember Regency. This research is located in Jember Regency and was conducted from July 2021 to December 2021. The sampling technique was cluster random sampling with a total of 200 respondents. The data collected in this study were analyzed by statistical descriptive analysis and multiple linear regression model analysis. The results show that farmers’ perceptions of the performance of agricultural extension workers during the Covid-19 pandemic are very satisfied. The factors that influence the perception of farmers are the frequency of extension, the level of farmer’s participation, and farmer’s knowledge. Meanwhile farmer’s experience, farmer’s group class, and land tenure had no effect on farmers’ perceptions of the extension workers’ performance.

Abstract
Indonesia has ratified The Convention on Biological Diversity (CBD) through Law Number 5 of 1994 with considerations that biodiversity, including ecosystems, types, and genetics of animals, plants, and micro-organisms, need to be guaranteed for their existence and sustainability for life. However, the management of Marine Conservation, which is also one of the implementations of CBD ratification, has not provided firm and clear legal protection for managing marine and coastal environmental areas. The management of marine conservation itself is a manifestation of sustainable development that stated in the Sustainable Development Goals, Goals 14, Conserve and Sustainability use the oceans, seas, and marine resources for sustainable development, and it is clearly seen that the principles of sustainable development have not been effective synergized in the implementation of CBD in Indonesia. This study uses a normative judicial approach with descriptive analytical research. The result of the research is The regulation of underwater biodiversity related to a sustainable environment which is regulated by various international, national, and local provisions, must be explicitly determined about the importance of protecting and conserving biological diversity, including marine biodiversity. The related framework also should accommodate its availability and ecosystems for a sustainable environment and human benefits for present and future generations. As a result of the destruction of marine ecosystems, marine biodiversity must be given sanctions for the violators. The sanctions can be in the form of administrative sanctions, criminal sanctions, or civil sanctions.

AbstractShark diving tourism opens opportunities to study shark behavior towards diver. As one of the popular attractions for the marine tourism in Indonesia, shark diving play significant role for the conservation in the eastern part of Indonesia. Banda Sea, as well as Morotai, Derawan, Raja Ampat, Nabire and Teluk Cenderawasih, Bali, Lombok, Komodo, and Gorontalo, is famous for its shark diving attraction. Despite its famous status as a tourism attraction, little is known about the behavior of scalloped hammerhead shark during the interaction with Self-Contained Underwater Breathing Apparatus (SCUBA) diver. The information of scalloped hammerhead shark movement behavior during interaction with SCUBA diver is important for developing ecological assessment, safe diving practice, and shark tourism carrying capacity. This research involves DOV (Diver Operated Video) to record the movement patterns of shark while interacting with SCUBA Diver. Evaluation of approximately 457 photos and 32 videos of theSphyrna lewiniduring 14 days of observations has been analyzed during SCUBA diving shows the most common shark agonistic display: pectoral fins depression - apart from other displays such as tail slapping, flank displaying, charging, snout raise, and jaw gapping. It also reveals three (3) new shark agonistic postures which were never been recorded previously: charging, snout raise, and jaw gapping. This study showed that there are consistent behaviors observed while meeting with SCUBA divers and this may be beneficial for development of safety diving management, as well as conservation efforts.

Abstract
The interaction between offshore waves and complex reef bottom profiles determines the hydrodynamic processes within the reef beaches, for instance, Sea-Swell (SS) wave dissipation, Infragravity (IG) wave generation as well as wave-induced currents and setups. These hydrodynamics phenomena are important to several ecological processes and control the associated shoreline erosion and flooding. Hence, a good understanding of the dynamics is needed that wave observations are challenging and expensive otherwise. Here we present a short term (12 hours) investigation of non-directional spectral waves using a series of HOBO pressure sensors. Six pressure sensors were deployed at 3 locations along the fringing reefs of Tunda Island, Banten Province - Indonesia. The wave spectra were estimated from the surface water fluctuations using linear wave theory for each hourly burst data. During observation, the Tunda waters were calm with significant wave heights were less than 10 cm with peak wave periods of ∼12 s at all sites. Despite the short period measurement due to memory issue, the result demonstrated the ability of HOBO pressure sensors to measure non-directional wave spectra at shallow water.

Published: December 2022

Abstract
Manipulation chromosome through heat shock treatment is safe method and can be applied to mass production in order to fulfil demand in animal food industry. The aim of the study was to evaluate how heat shock affected fertilized eggs after 4 minutes (triploid) and 40 minutes (tetraploid) of fertilization. After heat treatment of Clarias gariepinus fish eggs, the rate of abnormality of fertilized eggs were also determined. Heat shock treatments were 39°C, 40°C, and 41°C for 4 minutes, with times of 4 minutes after fertilization and 40 minutes after fertilization, with three repetitions of each treatment. The results showed that heat shock after 4 minutes of fertilization significantly affected the rate of slow embryonic development starting from the cleavage stage of 8 cell up to hatching compared to treatment 40 minutes after fertilization. The treatment with a shocking temperature of 41°C after 4 minutes of fertilization resulted in the highest percentage rate of abnormalities, 45.67%. Thus, this study revealed that tetraploid development was superior to triploid development due to higher egg abnormalities in triploid. Tetraploids are preferable as broodstocks to produce sterile triploids and can enlarge rapidly.

Published: December 2022

Abstract
The faster growth and higher survival of a strain, including the giant freshwater prawn (GFP), is an urgent requirement to support GFP farming. The selective breeding of GIMacro II (the superior strain of GFP) resulted in a fourth-generation (G4) which grew faster (35%) than the based population (G0). The comparative test among the selected GI Macro II (SGM), the control of GI Macro II (SGM), and the Siratu (SR, the previous superior strain) were conducted to evaluate the performance of these strains in the larval rearing phage, resistance to vibriosis of the larvae, and tolerance to stressors (pH, temperature, salinity, and formaldehyde) of the juvenile. In the larvae rearing stage, the growth (Larvae stage index, LSI) of the three populations was not different, there were 10.25 ± 0.14, 10.31 ± 0.18, and 10.12 ± 0.15 for SGM, CGM, and SR, respectively. The survival rate of the SGM is about 59.92 ± 4.631 %, significantly higher than the CGM larvae (52.67 ± 2.64 %) and SR larvae (45.85 ± 1.74 %). The resistance level of SGM larvae to Vibrio sp. infection (72.75 ± 4.88 %) is not different from the CGM larvae (70.25 ± 5.06%) and SR larvae (67.88 ± 6.59%). The tolerance level of the SGM, CGM, and SR juvenile to low pH, formaldehyde, temperature fluctuation, and salinity fluctuation were relatively high (>90%). The data suggested that the selected GI Macro II has a good prospect to be developed in the GFP farming system.

Abstract
The research was conducted to determine the productivity conditions of tilapia cultivation in the field along with the implementation of reducing the number of floating net cages. Production observations of tilapia culture were carried out on net cages owned by fish farmer in the Jatiluhur Reservoir from 2012 to 2019. The first period-P1 (2013-2015) was before the reduction in the number of net cages, the culture used a double net system and hybrid system. The second period-P2 (2016-2019) when the program started, KJA culture was carried out with a self-maintenance system (100% feeding for tilapia). The value of fish harvest weight ranged from 96.39-102.47 g (P1) and 196.84-278.33 g (P2). The range of survival rate is between 56.99–78.79% (P1), and 60.92–80.41% (P2). The feed efficiency value obtained in the P2 period was 75.77–86.34% while for P1 it was not defined because it was not a 100% feed system (independent). The daily weight gain, productivity and multiple values were as follows: 0.58-1.0 g/day, 0.14-0.45 g/m2, and 2.35-4.56x (P1); 1.43–3.00 g/day, 1.92–2.89 kg/m2 and 6.77–10.80x (P2). The monitored water quality parameters were still within a tolerable range for tilapia floating net cage culture.
