Published: April 2021

Abstract
Newly developed earth reinforcement for slope protection was applied in cold region. The reinforcement by this method is making use of precast concrete panels with insulation and anchor nails. The precast concrete panel is economical, of high quality, durable for weathering, earthquake-resistant and of good appearance, which contribute shortening construction period and less life cycle cost. We can construct for nearly vertical slope by placing panels downward from top of slope at the same time of slope cutting, and for reinforcing of existing retaining wall by simply covering and nailing as well. Practical case of design and construction is explained, and measurement results of temperatures, forces at anchor head during cold season are shown to ensure the protection. Especially concrete panels are designed with insulation for low temperature, and the result of thermal analysis and field measurement shows the insulation works well to stop freezing front going into ground.

Published: April 2021

Abstract
Peatland fires and deforestation are prominent environmental issues in Indonesia due to industrial and plantation activities. The Indonesian government is pressured to take mitigation measures to overcome the issue since there are legal obligations to do so. One of the climate mitigation strategies is by establishing a carbon market in which the entities will be assigned certain ‘permits’ on how much greenhouse gases (GHG) emissions can be emitted, and when they have exceeded their ‘permits’, they are allowed to buy ‘extra permits’ from the other entities who still have the spare. This market has been adopted by the European Union (EU) and other countries in Asia. Therefore, this paper aims to introduce the carbon market concept by taking into account its implementation in the EU, as well as analyse how the market can become one of the climate mitigation policies in Indonesia. The research uses a doctrinal methodology that involves an in-depth legal analysis of the regulatory framework related to the issue. The authors found that the market will enhance the REDD+ Project and projected to bring revenues. However, there are challenges due to the absence of technology and the number of stakeholders involved.

Abstract
The Dawuan Sub-watershed in Mojokerto Regency is a prone area to floods. There were flash floods in this area in 2002 and 2019, which caused casualties and property losses. As one of the mitigation efforts, this study aims to map a flash flood’s susceptibility using the LR-FR combination machine learning technique (logistic regression and frequency ratio). 11 conditioning factors are used to assess landslide susceptibility, namely: slope, aspect, TWI (Topographic Wetness Index), TPI (Topographic Position Index), SPI (Stream Power Index), profile curvature, distance to drainage, rainfall, geological unit, and land use. The results of the flash flood susceptibility mapping show that areas with very high levels of susceptibility have the following characteristics: slope < 8-35°; aspect east and southwest; TWI >16; TPI <(-3,39)-(-0,06); SPI <50-200; profile curvature (-0,001)-0,0; distance to drainage <10-40; rainfall <2000; geological unit Qvwl, Qvlw3, Qvlp3, Qvlp4, Qvwl, Qvf3, Qvf4 and Qvf8; and agricultural land use. The validation results show that the quality of the LR-FR model used has very good quality, as indicated by the AUC value = 0.93.

Published: April 2021

Abstract
Vibration is a common problem in concrete slab system when designed using ultimate strength capacity which producing slim structure. Although this elemen strong enough to sustain the loads, however another problem emerges because vibration of the element is not anticipated during the design. This study was selected from experimental data conducted on two story buildings system. Thin slab member of 120 mm in two story building showed vibration problem during sevice life. Two sensors were located on slab and middle beam to study behaviour of slab system due to human activity load. Numerical study was elaborated in this research for comparison. Strengthening of the slab using Fiber reinforced polymer (FRP) was applied to the slab system to reduce detrimental effect of vibration on slab. Peak acceleration of slab strengthening using FRP was brought down to 0.018 m/s2 and 0.013 m/s2 for damping of 2% and 3% respectively compared with unstrengthening slab which was 0,09 m/s2 which higher than accepted criteria 0,5% G (0,045 m/s2).

Published: April 2021

Abstract
Shrimp culture is carried out by ponds in open areas, especially near coastal areas. The ponds water condition or water quality has a significant impact on the shrimp culture. There are also frequent problems among these shrimp ponds, such as crop failure caused by bad water quality. The water quality monitoring in shrimp ponds is often done manually by the farmer in periodical times. The water quality monitoring that is done manually tends to be impractical, requires high worker wages, and has a high human error rate. With the advances in the field of Information Technology, data may be retrieved through sensors and collected into a server. Then the data may be processed and visualized in order to support precision aquaculture using the Internet of Things (IoT). Precision Fish Farming (PFF) or precision aquaculture is a concept that applies control-engineering principles to aquaculture industries. The PPF concepts allow farmers to have the ability to monitor, control, and document biological processes in aquaculture farms. This research aims were to design and build a multi node sensor and master board to monitor water quality in real time using the prototyping method. The system consists of several sensors for monitoring temperature, pH, and salinity in shrimp ponds that are installed at each node. Nodes are actively sending data to the master board. This model is done to reduce the need for direct data access to the internet. The monitoring system is tested in PB Tunas Baru shrimps pond in order to check if the system may work properly. The sensor is set to retrieve pond water quality data every 5 minutes in a total 100 minute period. The result shows that the model works properly, and the means value of the total error rate for the salinity sensors, pH, and temperature sensors consecutively is 1.65%, 1.25%, and 0%. This information allows the farmers to maintain the water quality precisely in aim to produce high quality shrimp crops toward the precision aquaculture concepts.

Abstract
The prohibition of using cantrang fishing gear in the waters of Lampung Bay is one of the government’s efforts to reduce marine ecosystems’ problem. Polemic in the form of pros and cons of implementing the cantrang prohibition policy, has resulted in a wave of rejection and the emergence of horizontal conflicts between fishermen, a shift in vertical conflict against the government. The role of stakeholders in the failure and success of public policy implementation is very strategic. The study aims to conduct a stakeholder mapping analysis of the cantrang prohibition policy. The research was conducted at the Lempasing Beach Fishing Port, Bandar Lampung City, Indonesia, in July-September 2019. The method uses the Power versus Interest Grid Analysis. The results illustrate stakeholders’ identification from the classification of strong supporters and strong opponents with their interests, resources, influence, and actions taken. Using the stakeholder role matrix, information on comparative, influential, involved, and only receives information is obtained. Contribution: improve governance, and prepare policies that can resolve polemics, improve fishermen’s welfare and protect underwater ecosystems.

Abstract
The presence of weeds during the vegetative growth of pineapple plants could reduce production by up to 88%, so weed control is necessary. One way of controlling weeds is by use of herbicides. However, continuous, long-term application of herbicides could result in environmental pollution and weed resistance to the herbicides. This research aimed to identify the resistance of E. indica weeds to herbicide diuron and to compare the growth characteristics of diuron-resistant and diuron-sensitive E. indica. The resistant weeds were taken from the pineapple plantations under continuous, long term application of diuron herbicides, while the sensitive weeds were taken from areas which have never been applied with diuron herbicides. This research was conducted at the University of Lampung, from February to October 2020. It consisted of two experiments, The experiment 1 : the response of E. indica to diuron and The experiment 2: the growth characteristics of diuron-resistant and diuron-sensitive E. indica. In the experiment 1, experiments were arranged in a split plot design with five replicates and the treatments consisted of two factors. The first factor consisted of the diuron-resistant and the diuron sensitive E. indica and the second factor was diuron dosage (0, 1600, 3200 and 6400 g ha-1). In the experiment 2, The resistant and sensitive E. indica were compared using t-test. The study revealed that the diuron-resistant E. indica needed a longer time to be 50% damaged than the sensitive one. The resistance index (RI) of E. indica to diuron was 2.80, indicating low level of resistance. The diuron-resistant and diuron-sensitive E. indica did not significantly showed different growth characteristics.

Abstract
The COVID-19 pandemic situation is still ongoing in many countries in the world, including Indonesia. The positive case continues to increase every day and impacts our life, including the fisheries’ family. The fishery is a vulnerable sector to climate change, and this day worsened by a pandemic situation. This paper aims to understand the resources attached to fishing families facing various pressures and risks, forms of response, and adaptation within the fishing families. During COVID-19 pandemic situation, we have to carried out an online ethnographic approach by online-focused group discussion (FGD) to fisherman group and fisherman wives. Purworejo village was selected as a research site because it is the one with the largest number of small-scale fishing families in Java’s northern coastal area. The results show that various pressures and risks faced by fishery families, not only related to climate change and COVID-19 such as fishing season, limited resources, capital, and access, but also a risk on their internal family. In the context of fishery family resilience, each family member has a role in dealing with stressors, especially economic stressors. Fathers look for fish in the sea almost eight hours a day; children also go to sea when economic conditions continue to deteriorate; even a fisherman’s wife has the same responsibilities as her husband.

Abstract
Food security is a condition in which food is available to every individual at any time, both physically and economically. In line with the Sustainable Development Goals, the Indonesian government has made efforts to improve food security, especially rice as main staple food. This study aims to know the form of purchased rice of household in urban and rural areas and to examine the relationship between household residences on decisions about where to purchase rice in a sustainable development era. This study uses micro data of 1047 households, consists of 486 urban households and 561 rural households. The data was collected through web survey in August 2020, then it was analysed by using descriptive method. The results showed that households in urban and rural Indonesia had quite different decisions in purchasing rice. The rice purchasing in modern places, such as supermarkets and minimarkets, is mostly carried out by urban households. Meanwhile, rice purchasing in non-modern places, such as markets and rice millings, is mostly performed by rural households. In addition, households in the rural area also prefer to buy uncooked rice from rice milling and farmers, and some households do not buy rice since they have owned rice fields. The number of household who buy cooked rice is larger in urban than in rural. Urban household is more widely on where to purchase rice than rural households.

Abstract
From Bali cultural tourism, traditional myth is the pulling power that makes the tourist come. The existing condition shows that culture only a symbol and not being involved in regulating tourism products. This paper aims to understand how traditional myth, as one of the social environment assets in sustainable tourism development, is forgotten. The method used refers to the qualitative methodology with qualitative methods, qualitative techniques, and qualitative analysis using hermeneutic methods. The results showed that traditional myth as a cultural asset of tourism should be linked with sustainable tourism development, as traditional myth can be preserved and at the same time can be utilized for tourism. Therefore, it is essential to collaborate preservation efforts with the economic value of culture.
Understanding consumers’ behaviour for reducing environmental and social impact through sustainable product design – A Study case of vehicles usage in Indonesia
Authors: Hamni A , Panuju A Y T , Ambarwati D A S 
Published: April 2021

Abstract
One of crucial aspects in achieving a better level of sustainability in a country is the society’s responsible product consumption pattern, as descripted in The United Nations’ Sustainable Development Goals (SDGs). Inevitably, the dynamic interaction between consumers and products creates negative effects to the social and environmental dimension, including emissions from all the product’s life cycle phases. Among other products, the usage of private combustion engine vehicles in Indonesia is one of the highest emission producers and a highly fuel consuming product. While the exploitation of these vehicles for fulfilling basic needs is essential to increase the society’s quality of life, extended behaviour related to the vehicles may come from unimportant desire and endangers the dimensions of sustainability. This paper reveals the consumers’ problematic behaviour and their reasons, as a part of a sustainable design framework, by conducting survey and in-depth interview sessions. Subsequently, the data is analysed qualitatively using thematic analysis method. The results may address strategies for the manufacturers in designing future eco-friendly vehicles and also gives recommendations for other stakeholders in creating policies and educational programs for the society.

Published: April 2021

Abstract
The mechanization of rice farming has been fast developing since implementing the special effort (Upsus) program in 2015. Through this program, many combine harvesters and four-wheel tractors had been distributed to the farmer groups. This study’s objectives were to know the practice of sustainable agricultural mechanization, know its impact on land productivity and profit for rice farming, and know whether sustainable agricultural development in Lampung Tengah Regency. This study was conducted at three sub-districts, Central Lampung Regency, in August and September 2020. Respondents were 108 farmers with 359 observations since each respondent was interviewed for 3-4 previous planting seasons, and an observation was a rice farm in a planting season. To know the practice of the mechanization, the data were analyzed descriptively. To know its impact, the data were analyzed using two multiple regression analysis models, each of which the dependent variable is productivity and profit. The independent variables for these two models were the mechanization types, the treatment variables, and the planting seasons and location, which were the control variables. The results revealed that the 4-wheel tractors were more efficient than that of the 2-wheel tractors. Combining harvester (CH) was the most efficient in harvesting than that of manual cutting and thresher and full manual harvesting. The results revealed that statistically, with the level of significance (α) by 1%, the combined harvester’s use increased the average productivity by 0.16 tonnes/ha or almost 3%, i.e., from 5.51 tonnes/ha to 5.67 tonnes/ha. They increased the average profit by IDR2.44 million/ha or 40%, i.e., from IDR6.10 million/ha to IDR8.54 million/ha. These findings revealed that the use of a tractor together with a combine harvester was sustainable agricultural development.
Static and dynamic panel models: Which is better? (Case study: Poverty data in Indonesia 2012-2019)
Authors: Sihombing P R , Arsani A M 
Published: April 2021

Abstract
Indonesia’s poverty rate continues to decline from year to year; however, the decline in the percentage of poor people is slowing down continuously, following the law of diminishing returns. Many factors influence poverty, including HDI, Gini ratio, and the open unemployment rate. This study model static and dynamic panel data on Indonesia’s poverty cases in 2012-2019 to explain the relationship between HDI, Gini ratio, and the unemployment rate to poverty. It also compares poverty modeling with static and dynamic panel data regression. The results show that the Gini ratio has a significant and positive relationship to poverty. HDI has a significant and negative relationship to poverty. However, there is insufficient evidence to suggest that unemployment affects poverty. Using static panel data regression, the selected model is a fixed effect model but still experiences violations of the classic autocorrelation assumption. The dynamic panel data model gives better results than the static panel data regression model when viewed from the r-square value and the number of variables that significantly affect. From the results of this study, it can be implemented that an increase in economic growth without an increase in equity has no impact on poverty. So, it needs extra efforts by the government in economic equality for all regions of Indonesia. Also, there is a need for additional actions by the government and the community to improve education, health, purchasing power, and community competitiveness.

Abstract
This study discusses students’ perceptions, attitudes, and lifestyles of the Madrasah Ibtidaiyah Teacher Education Program at Siliwangi Islamic College regarding Education for Sustainable Development (ESD). The research was conducted in October 2019 involving 86 students of PGMI study program through a survey that focused on knowledge of ESD, attitudes, and lifestyles of st sustainable development concepts. This research uses descriptive analysis. In terms of understanding found inconsistency of respondent’s knowledge of ESD, it can be seen from 74.4% of students have heard the term ESD, 70% stated understanding of ESD, but only 24.4% of respondent were right when asked about the definition of ESD. In terms of attitude, respondents are in a very good category (85.63%) it means that respondents understand how to behave according to the ESD values in daily activity. But this is not in line with the curriculum in Madrasah Ibtidaiyah Teacher Education Program at Siliwangi Islamic College. The curriculum, especially mandatory subjects at the Madrasah Ibtidaiyah (MI) or elementary school, does not contain the values or activities related to ESD. While on the other hand, the concept and program of ESD have been introduced since 2002 by UNESCO and participated in by many countries through educational programs ranging from primary education to higher education. This research is very important to produce a picture of ESD competence integrated into the curriculum in the madrasah ibtidaiyah teacher education program.
