Uncertainties in modelling undrained shear strength of clays using Critical State Soil Mechanics and SHANSEP
Authors: D’Ignazio M , Phoon K K , Länsivaara T T 
Published: April 2021

AbstractThe determination of the undrained shear strength of clays relies upon the goodness of the available in-situ and laboratory tests. Often, limited soil investigation data is available, or the collected data may suffer of low quality associated with poor test execution or sampling operations. The use of reliable correlations can then play an important role in geotechnical design. In that perspective, it is vital to choose the most appropriate correlation models that are suitable with the local soil conditions and that are possibly characterized by low uncertainty. The SHANSEP empirical model describes the undrained shear strength of clays in terms of normalized properties, where the soil strength is defined by means of the overconsolidation ratio (OCR) and two material coefficients that require empirical calibration. The SHANSEP model can be further combined with analytical solutions based on Critical State Soil Mechanics (CSSM) in order to define the undrained shear strength as a function of two fundamental properties, such as the preconsolidation stress (or the OCR) and the friction angle at critical state. The paper deals with the uncertainties associated with modelling the undrained shear strength of clays using a hybrid CSSM-SHANSEP model. The performance of the model is assessed by comparing the predicted undrained shear strength to an existing multivariate database of field vane data points from Finland. For each data point, the friction angle is estimated indirectly from the plasticity index using a correlation in the literature, while the OCR is taken directly from the database. Bias and uncertainties of the CSSM-SHANSEP model associated with the multivariate database are evaluated. Finally, a sensitivity study on the model parameters is presented.

Abstract
Indonesia’s population is increasing every year, so many household needs need to be met. As a result, a lot of household waste has accumulated in FDS (Final Disposal Sites). This condition is very disturbing to the health of the people living around the FDS. Therefore it is necessary to compost household waste which can minimize the pile of garbage in the FDS. One of the methods is using BSF larvae. BSF (Black Soldier Fly) larvae are larvae that can consume various kinds of organic waste, such as household waste, quickly. The experimental results show that household waste compost has micronutrients that comply with Indonesian composting standards (SNI 19-7030-200). Micronutrient elements from household waste compost using BSF are Zink (60.55ppm), Manganese (36.55ppm), and Boron (12.07 ppm). Also, compost from household waste using BSF, the toxic elements cannot be detected, so it is safe to be applied as a nutrient for plants.

Abstract
Increasing access to proper sanitation in urban areas in Indonesia has not been accompanied by the availability of a domestic wastewater disposal system that is safe for the environment. The existing domestic wastewater management system is felt to be unable to prevent pollution. Several studies have reported contamination of water bodies in several cities originating from domestic wastewater that has not been appropriately managed. This paper aims to discuss the developments of the domestic wastewater management system in Indonesia by exploring the current conditions and challenges. The service capacity and application of domestic wastewater treatment technology at wastewater treatment plants already operating in Indonesia will be discussed to find out the existing comparisons. Several regulations related to the domestic wastewater management system also be reviewed to find out the policy direction of pollution prevention efforts. From the conditions exposed, it is necessary to evaluate and adjust the existing concepts to the progress of developments in the field. More significant effort is needed to find solutions for problems and realize the domestic wastewater management system’s implementation to achieve the desired goals.

Published: April 2021

Abstract
This research is driven by the phenomenon of the increasing trend of population migration from agricultural and coastal areas due to climate change. The impact of climate change that is felt most severely by the population is the reduction in agricultural production, which then impacts decreasing household income. To meet household economic needs, some residents respond by migrating outside the village in search of work. This research uses a qualitative approach with in-depth interview techniques, Focus Group Discussion (FGD), and observation. The research locations were East and North Lombok Regency, NTB Province. The results showed no management of migration due to the impact of climate change by the NTB provincial government and district governments. There are no programs aimed at facilitating migration due to the impacts of climate change. Therefore it is necessary to include migration as a strategic issue in the adaptation and mitigation action plan to address the impacts of climate change at both the national and regional levels with the Ministry of Manpower and its aides-de-camp as the sector leading.

Abstract
The proboscis monkey is an endangered primate endemic to Borneo. Most of their habitats are outside conservation areas and are under threat from conversion to other land uses, such as those found in the Berau Delta. Habitat loss and destruction significantly affect the quality and viability of the proboscis monkey population. This study aims to determine land cover and proboscis monkey habitat types in Berau Delta. Land cover was obtained from the interpretation of the Lansat 8 OLI 2019 satellite image. Vegetation data were collected using a line plot transect method and continued with cluster analysis. The results showed that mangrove forest has the largest coverage (35.92%), followed by secondary forest (17.10%) and riparian forest (12.96%). At least 74 species of woody plants belonging to 61 genera and 37 families in a 2.4 ha observation plot. The range of species diversity index was from 0.80 to 2.88, and; evenness index values range from 0.58 to 0.82. The habitat was categorized into two main clusters: mangrove cluster (Buasin Cape, Guntung Estuary) and riverine cluster (Lati River, Saodang Kecil Island, Batu-Batu, Bebanir Lama). The mangrove forest habitat consists of Rhizophora mucronata, R. apiculata, Bruguiera sp, Sonneratia alba, and Avicennia alba. The riparian habitats are dominated by Sonneratia caseolaris, Vitex pinnata, Cerbera manghas, Brownlowia argentata, Heritiera littoralis, Syzygium lineatum, Nauclea officinalis, Xylocarpus granatum, Syzygium sp.1, and A. alba. The average of total and lower branches height of trees in the Lati River and Basin Cape were higher than in other habitats, forming a continuous canopy.

Authors: Istianto M , Emilda D 
Published: April 2021

AbstractOne of the main obstacles in tropical fruit cultivation is pests and diseases. It is necessary to apply safe pest control for consumers and the environment. Indonesian Tropical Fruit Research Institute (ITFRI) studies the potency of several essential oils for pests and disease control on tropical fruit for many years. These studies aimed to evaluate the effectiveness of Citronella and clove oils in controlling pests and diseases. These studies were conducted in laboratory and field conditions by comparing the development of pest and disease symptoms on essential oils treated plants and untreated control or among several essential oils treated plants. The results showed that clove oil could inhibit the development of powdery mildew in rambutan and Phytophthora palmivora that caused diseases in durian. Citronella oil decreased ant attack and scarring symptoms on mangosteen fruits. Research activities to test the effectiveness of these two essential oils in field conditions need to be intensified so that this technology is truly effective, efficient, and right on target.

Published: April 2021

Abstract
The interpretive sign is to communicate specific educational and/or management learning, behavioral and emotional messages to visitors. Interpretive signs are most commonly used for self-guiding trails, or for wayside exhibits at points of interest. This study aims to assess the effectiveness of interpretation signs on biodiversity at the Dramaga IPB Campus. The research was conducted at the Dramaga IPB Campus, Bogor in January-March 2020. This research was conducted through field observations, literature and document studies, and interviews using a questionnaire to 90 respondents classified into the general public, students, and lecturers. The signs effectiveness assessment is approached based on three components: layout, design, and media content. The results showed that the media for interpretation of the Dramaga Campus of IPB as the center for tropical biodiversity information was considered ineffective. This is because there are only seven criteria out of 14, which are considered effective based on the assessment of field observations and the results of respondents’ assessments. The criteria that are considered effective are not obstructed by other objects, protected from sunlight and rain, using illustrations, appropriate board height, the suitability of themes, and illustrations’ suitability. Eight areas are considered effective, and five areas that are considered ineffective.
