Published: August 2021

Voice Communications is still playing important role in business activities. Large companies generally use PBX to handle corporate communications both internally and externally. PBXs have rich features that can fulfil corporate voice communications requirements. Internet changed the corporate communications importance from voice centric to data communications. Intranet becomes the strategic data infrastructure for internal communications and its connection to Internet is an absolute must to have global reach. Voice over IP (VOIP) is the technology that capitalizes the ubiquitous presence of data network in corporates. VOIP provides efficiency in business communications. Naturally, traditional PBX evolves to IP-PBX that use data network which is currently based on TCP/IP for certain connections. The acceptance of SIP (Session Initiation Protocol) as the protocol for VOIP resulted in improvement of IP-PBX to become SIP-PBX. One of the SIP-PBX that is Open Source is called Asterisk. It has rich features found in high end corporate PBX. In this research Asterisk is used as the basic PBX for small corporates in fulfilling corporate voice communications. Sometimes small companies have to operate in locations that have no proper and reliable fixed or cable infrastructure for Internet connection. The only economic viable choice is 3G or 4G cellular service. The problem is whether the service quality is suitable. ITU has recommendation for planning of telephony transmission quality. The parameter is known as MOS. The recommendation shows detailed variables to reach the MOS. Based on the ITU recommendations; this research provides a novel technique to quickly assess the voice quality of internal voice corporate communications using SIP-PBX that is located in the Internet. The data used for evaluating MOS can be directly obtained using Wireshark as the tool. The resulting MOS used only to assess whether the 3G or 4G service in that particular location is suitable for small corporate communications or other solution should be found. This research result showed that based on MOS, 3G access line quality is inadequate for VOIP based voice communication.

Published: August 2021

The aim of this study was to examine the fatty acid composition and sensory acceptance of Indonesian shortfin eels meat (Anguilla bicolor) in two consumable sizes (small and large) as compared to farmed Atlantic salmon meat (Salmo salar) that are commonly consumed by Indonesian consumers as a source of nutrient and omega-3. Fatty acid analysis was carried out by fat extraction and gas chromatography. Data obtained was analyzed by ANOVA. Results revealed that the highest total fat content was found in small eels (23.75 / 100 gr), followed by large eels (18.52 / 100 gr) and salmon (15.98 / 100 gr). Meanwhile, the highest total fatty acid content was found in salmon (88.07% w/w), followed by large eel (81.88% w/w) and the small eels (75.68% w/w). Saturated fatty acid (SFA) was found more abundant in eels of both sizes whereas salmon contains a higher amount of monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA). Both small eel and large eel contain 25 types of fatty acids, while salmon contains 24 types of fatty acids with heneicosanoic acid being the fatty acid absent in salmon. Sensory evaluation using hedonic scale demonstrated panelists’ preferences for texture (firmness, juiciness), aroma, taste, and overall of boiled salmon were not significantly different from boiled eel. The panelists’ preference for the aroma, taste, and overall of boiled eel with dipping sauce was also not significantly different from steamed salmon with dipping sauce. In conclusion, our study suggests that Indonesian shortfin eels present a commensurable if not greater fatty acid composition and palatability compared to Salmon.

Assessing the cultural state after the disaster as a driver for sustainable development
Authors: Rahmayati Y
Published: August 2021

In disaster situations, physical buildings and infrastructures can be damaged or destroyed, including the community’s livelihood, yet generally, the cultural structures that shaped the settlements persist. However, local cultural values have been commonly ignored in a postdisaster intervention. It creates conflict, which results in improper development practice that contributes to the weak sustainability outcomes. Using the Aceh tsunami disaster as a case study, this study examines how far the community recognises their cultural values after the disaster. It argues that culture is a potential resource that is significant for community building. Thus, assessing the cultural state of the affected community is vital to be carried out for the longer term of sustainability of the new development. The study relied on a qualitative approach as the primary methodology. The data was collected through a series of fieldwork, which involved indepth interviews and site observations. It was supported by desk research to gather related statistical information and literature. The study targeted all levels of the community ranging from young people, elderly, key persons (such as the head of the village and religious leaders), male and female, educated, and uneducated people. The desk research was conducted to get the overview and background information regarding the history of the places, significant values, profile of the areas, and the statistical data. Both tangible (such as substantial buildings, monuments, and sites) and intangible aspects, including everyday life, cultural interaction, and traditional practices were assessed. The study covered the area of Banda Aceh city and part of Aceh Besar district. Both were the devastated areas hit by the tsunami disaster of 26th December 2004. Studies on the importance of culture for sustainable development have been carried out; however, this study will be different since it focuses on sustainable development in the context of post-disaster, which was not commonly studied. The results of this study offer a lesson learned and provide a recommendation for the planning of sustainable development after a disaster. It may also contribute to the development studies and practices in general.

Poverty is the inability to meet the basic needs of life, both for food, clothing, and shelter that might happiness of the people’s life. By collecting both primary and secondary data, the main objective of this study is to determine the level of happiness of the people divided into poor and non-poor households, so that this research might bring a better understanding of poverty in Indonesia, with special case of Kedungkandang District, Malang City through the measurement of Happiness Index covering three dimensions. Happiness threshold is at a scale of 60-79,9 namely Happy level, result research indicates that the district has a quite happy level for the people whole live in it with an average value of the HI at about 44.62. Some important variables to be noticed from the three dimensions are the LSI indicates that in general district residents have higher social satisfaction than their personal, the LAI whereby variables of unworried and undepressed at some sub-districts indicate the very low value, and the LMI wherein neighborhood control has the very low value. For future research, it seems important to scrutinize the social structure of the community to find better possibilities on dealing with poverty through their social ties.
Socio-Economic Analysis of Creating Coastal Reservoir in Welang Coastal Area, Pasuruan: Comparison with on-land Reservoir
Authors: Rakhmawati A L , Armono H D
Published: August 2021

Welang river is located in a residential area and national road access as well as a productive agricultural area which must be maintained. Floods that often hit the location disrupt economic activity and regional economic growth. The estuary and the capacity of the river sections, especially around the estuary are not able to accommodate and drain the flood discharge. The flood overflows caused inundation in Pasuruan, especially on national roads, agricultural lands, and industrial areas. To control the destructive power of the Welang river, it is necessary to plan an appropriate infrastructure for flood control in the Welang River especially when the high water discharge meets the high tide. This paper discusses the comparison between coastal and on-land reservoirs. In addition, based on economic analysis, the Benefit-Cost Ratio for on-land reservoirs is 1 and for coastal reservoirs is 1,54. Therefore, the coastal reservoir project is more economically feasible to carry out than an on-land reservoir with less social impact. This study also shows that with the use of the coastal reservoirs, the river runoff, water supply, and the water quality in Welang river basins can be improved.

The waste bank is one of the formal sectors to reduce waste in the city of Surabaya. Sukolilo Sub-District has 22 active waste banks, but eight waste banks are inactive. Also, the TPS is carrying out plastic waste sorting. The sorting activity at the TPS is much greater than the reduction through the waste bank. The purpose of this research is to analyze the recovery factor (RF) through the waste bank and TPS. The method used is interviews with waste banks and TPS as the formal sector and collectors as the informal sector. The results show that the recovery factor (RF) in Sukolilo District is still far from standard. Plastic RF in Sukolilo District is 4.79% from the standard which can be reduced by 50%. This waste reduction involves the roles of the formal and informal sectors.

Smoked fish processing waste has a high nutritional content that can be used as a raw material for fish feed (pellets). One standard of fish pellets based on BSN is there must be no aflatoxin content produced from Aspergilus flavus. Qualitative analysis of aflatoxin content can be seen from the presence or absence of A. flavus fungi. In this study the identification of fungi on pellets, fish, and water for maintenance is discussed. Pellets made from smoked fish processing waste are grouped into: K.0 (control), K.1 (100% raw material + 0% fish feed), K.2 (70% raw material + 30% fish feed), K.3 ( 40% raw material + 60% fish feed), and K.4 (10% raw material + 90% fish feed). Pellets were given to African catfish for 30 days of maintenance. The identification of fungi was carried out on pellets, African catfish, and pond water. The identification results in three fungi namely Rhizopus oryzae, Aspergilus niger, and Fusarium oxysporum.

Population growth in Kupang has consequently led to an increase in solid waste generation. On the other hand, the provision of waste management infrastructures, such as temporary waste collection sites and waste transportation services, are not distributed equally in several areas. This condition and the community’s low awareness of proper waste management have resulted in the emergence of informal waste collection sites. This study aims to examine the distribution of formal and informal waste collection sites in regards to their distribution patterns, characteristics of the sites using a descriptive survey method supported by a Geographical Information System. The study was conducted in Alak and Kelapa Lima Sub-Districts, Kupang, East Nusa Tenggara. The study identified a total of 57 informal waste collection sites, 14 sites in Alak Sub-District and 43 in Kelapa Lima. The distribution of informal waste collection sites was influenced by geophysical factors, where 79% of collection sites were located on vacant land and 53% are on local roads. However, the distribution of informal waste collection sites was not affected by population density nor the type of settlement.

Water Treatment Plant (WTP) with conventional systems uses pumps that work for 24 hours, and chemicals that produce residues or by-products in water processing and have an impact on the environment and humans. This study aims to identify the quality and performance of the WTP treatment, Identify the impacts arising from the drinking water treatment process and determine the efforts made to reduce the impacts identified by the method Life Cycle Assessment (LCA). The Life Cycle Assessment (LCA) method is an assessment method regarding potential environmental impacts and evaluation of the environmental performance of a process to the product. Life Cycle Assessment (LCA) consists of four stages, are Goal and Scope determination, Life Cycle Inventory, Life Cycle Impact Assessment, and data interpretation. The software used in SimaPro 9.0.0 with the impact assessment method is CML-IA Baseline. The impacts discussed in this research are Global Warming, Human Toxicity, and Eutrophication. The way to reduce the impact is based on literature studies. The results of the analysis found that the quality of raw water has not reach the quality standards as drinking water standards. While the quality of produced water has reached the quality standard. The performance of the processing unit at WTP has not worked well, therefore needs improvement with the addition of polymer in clearator, electricity usage in WTP is 11.220.195,47 kWh/year. The analysis results using Life Cycle Assessment (LCA) method, showed that the highest contribution to environmental impact was Eutrophication of 287.644,1 kg PO4--eq/year followed by Global Warming of 23.697.275 kg CO2eq/year, and Human Toxicity of 9.190.241 kg 1,4-DBeq/year. The way to reduce the impact is to take pretreatment on raw water, plan and build sludge treatment, also recycle sludge from clearator unit, replace equipment, replace aluminum sulfate, and liquid chlorine into PAC and hypochlorite salts.
