Abstract. Alfian RL, Iskandar J, Iskandar BS, Suroso, Ermandara DP, Mulyanto D, Partasasmita R. 2020. Fish species, traders, and trade in traditional market: Case study in Pasar Baru, Balikpapan City, East Kalimantan, Indonesia. Biodiversitas 21: 393-406. The purpose of this study is to analyze the species of fish traded by fish traders in the Pasar Baru traditional market, Balikpapan, East Kalimantan. In addition, this study analyses the Traditional Ecological Knowledge (TEK) of fish traders on fishes, including naming fish, fish habitat and caught technique, sex differentiate, taste of fish, price of fish, origin of fish and processing, freshness of fish and preservation, and the transmission of knowledge and conservation of the fish species. This study used qualitative methods that ethnoichthyology approach was used, with some field technics, namely observation, depth interview, and survey of species of fish were applied. The results showed that there were 36 species, representing 22 families recorded in the traditional market of Pasar Baru. Fish traders have good knowledge on fishes, including naming fish, sex differentiate, fish caught, freshness of fish, and how to preserve fish. Traders often offer fish to buyers by mentioning the names and various aspects of fish species, so the traders have indirectly introduced and socialized the TEK of fish species to buyers and a wider community. In addition, since the high diversity of fish species has normally traded in the traditional market, it has an important function not only for the community's economy, but also have an important function for the conservation of biodiversity of fish species in the region.

Abstract. Sudiana A, Putri A, Napitupulu TP, Purnaningsih I, Idris, Kanti A. 2020. Growth inhibition of Fusarium solani and F. oxysporum by Streptomyces sasae TG01, and its ability to solubilize insoluble phosphate. Biodiversitas 21: 429-435. Actinomycetes have been widely explored for new antibiotic production, but not many studies explore its abilities to inhibit the growth of phytopathogenic fungi and solubilize insoluble phosphate hence stimulate the growth of plants. We isolated Actinomycetes from the soil. Based on morphology, physiology, and 16S rDNA analyses, the isolate is closely related to Streptomyces sasae. The strain was able to inhibit the growth of phytopathogenic fungi Fusarium solani, and Fusarium oxysporum. S. sasae produced secondary metabolites 2-methyl-1,3-dioxolane as the major constituent. The strain assimilated variable carbon sources include L-arabinose, D-fructose, D-glucose, D-mannitol, Lactose, raffinose, L-rhamnose, and sucrose. The strain grew at pH 6.0 to 8.0, and at salinity (1-3%). Their growth was affected by the salinity level. The strain solubilized Ca-P at 1-3% salinity, but their ability to solubilize phosphate was influenced by salinity. The strain was also able to solubilize rock phosphate. Their ability to solubilize less soluble phosphate and inhibit the growth of F. solani and F. oxysporum may imply that this strain is potential for biocontrol agents. The 16S rRNA gene was submitted to DDBJ with the entry number 5df623c1a3c8820021322a36.TG01, and the accession number is LC514451.

We report the first detailed descriptive osteocranium of keureling, Tor tambroides (Cypriniformes: Cyprinidae) collected from Tangse River, Indonesia. This study aimed to describe the cranium morphology of keureling (Tor tambroides). Keureling fish used in this study were obtained from the catch of fishers in the Tangse River, District of Pidie, Aceh Province, Indonesia. Stages of research include sample preparation, bone preparations, and identification of cranium nomenclature. For osteological examination, the cranium of the keureling prepared physically and chemically. Based on the results, the cranium of the keureling is divided into two major parts, namely the neurocranium and the facial bone,s including the branchial apparatus. The neurocranium is divided into (anterior to posterior) olfactory (ethmoid), orbital, otic, and occipital regions while the rest divided into oromandibular, opercular series, branchial arch, mandibular arch, and hyoid arch (suspensorium) regions. The neurocranium includes bones in the dermal series of the skull and endochondral bones protecting the brain. At the same time, branchiocranium are those located in the oromandibular part, opercular series, and branchial arch.

Abstract. Purba A, Hayati R, Putri LAP, Chalil D, Afandi D, Syahputra I, Basyuni M. 2020. Genetic diversity and structure of Ganoderma boninense isolates from oil palm and other plantation crops. Biodiversitas 21: 451-456. Oil palm is an economically important plant, which one of the most important sources of vegetable oil in the world. However, oil palm plantation and other crops face the treat basal stem rot (BSR) disease by Ganoderma boninense. A study on genetic diversity and structure of G. boninense is therefore needed in order to formulate improved control strategies for this disease. This work aimed to analyze the genetic diversity and structure of the G. boninense isolates derived from different hosts, 131 oil palm (Elaeis guineensis), six rubber (Hevea brasiliensis), three coconuts (Cocos nucifera), and three lontar palm (Borassus flabellifer). Genetic diversity and population structure of G. boninense isolates were investigated using six SSR markers with GenAlex 6.502 software. Results showed that several microsatellite loci indicated specific primary success rates, such as KT124402, KT124399, and KT124394, depicting high polymorphism content (>75%). This result suggested that these markers were equally effective in determining the polymorphisms of G. boninense isolates. A hierarchical analysis of molecular variance (AMOVA) revealed that genetic diversity mostly found among individuals within a population (88%), then among populations (8%), and within individuals (4%).. Phylogeny analysis showed two clusters of Ganoderma isolates. which was considered variation as dissimilar across with origin. The present study indicated that G. boninense from oil palm was predominantly comprised of a genetically distinct individual.

Abstract. Abdulah L, Suhendang E, Purnomo H, Mattangaran JR. 2020. Measuring the sustainability of wood consumption at the household level in Indonesia: Case study in Bogor, Indonesia. Biodiversitas 21: 457-464. Data on consumption of wood products at the end-user level does not yet exist. This is caused by variations in the shape of wood products and raw materials used. Meanwhile, information on the level of consumption per capita is needed to measure sustainability consumption at the household level, determine the volume of wood production and carbon storage in wood products in the household. The novelty of this study is in method for measure wood product consumption. The aim of this study was to estimate the level of wood consumption at the household level in the form of use for construction and furniture. The method used was a survey of wood products at the industrial level and to make a database and then confirmed to households to determine the level of consumption. The results showed that wood products in the household are divided into 2 main parts namely construction and furniture. The level of wood consumption varied greatly depending on the type of roof, the number of doors and windows and the amount of furniture used. The level of consumption in Bogor reached 0.1 m3 per capita. This consumption was influenced by the time of use and the size of family.

Abstract. Sherman J, Ancrenaz M, Voigt M, Oram F, Santika T, Wich S, Meijaard E. 2020. Envisioning a future for Bornean orangutans: Conservation impacts of action plan implementation and recommendations for improved population outcomes. Biodiversitas 21: 465-477. Populations of the Critically Endangered Bornean orangutan (Pongo pygmaeus) are declining despite more than 10 years of conservation action plan implementation. Here we analyzed the impacts on species' population and habitat from orangutan conservation strategies implemented between 2007 and 2017. We also assessed data on investments into orangutan conservation, orangutan population trends and landcover change in orangutan range between 2007 and 2017. Diverse strategies addressed the range of threats to orangutans but were not implemented at scales that impacted species’ level populations and habitats. Since 2007 orangutan populations and forests across orangutan range have declined, with orangutan killing and deforestation as the major drivers of loss. Protected areas have increased since 2007, notably in Malaysian range states and in Central Kalimantan, Indonesia. However, 80% or tens of thousands of orangutans live outside protected areas in Kalimantan alone. Our results underscore scientific findings that have demonstrated this species’ resiliency and modified previous understanding of their habitat use. Orangutans are regularly found using agriculture landscapes (acacia, oil palm, and timber plantations), and exploited forests. This plasticity must be considered to design more effective orangutan conservation strategies. We need to revise the notion of “orangutan habitat” to extend beyond forests alone, incorporating all landscapes where P. pygmaeus can be found. Orangutans cannot survive in exclusively monoculture production areas; they need some natural forest to fulfill their ecological requirements. However, individuals surviving in isolated forest patches or mosaic landscapes play an important role in sustaining the long-term viability of the local metapopulation through provision of crucial genetic, reproductive and socioecological connectivity. Our findings suggest removing these individuals through translocations weakens overall metapopulation health. All necessary efforts must be made to maintain individuals in isolated forest patches or mosaic landscapes in order to support healthy metapopulations. Improved orangutan population outcomes will require addressing habitat connectivity at the landscape level, incorporating both non-forested and anthropogenically modified areas, and developing efficient management strategies for human and orangutan co-existence within these multiple-use landscapes.

Abstract. Irsyad AF, Rindyaastuti R, Yulistyarini T, Darmayanti AS, Daryono BS. 2020. Genetic variation of agarwood producing tree (Gyrinops versteegii) from Pongkor, Manggarai District, Flores Island, Indonesia using ISSR molecular markers. Biodiversitas 21: xxxx. Agarwood is a black-colored tree wood that produces distinctive sap because of fungal infections which belong to Thymelaeaceae family (mainly Aquilaria and Gyrinops). Agarwood product is highly valuable that leading to over exploitations by the collectors. To develop the most effective and efficient conservation strategies, genetic information from these plants is required. The aims of this research are to determine the genetic variation and to confirm the species identity of agarwood producing tree (Gyrinops versteegii (Gilg.) Domke) population in Pongkor Community Forest, Pongkor, Manggarai District, Flores Island, East Nusa Tenggara. Information of the genetic variation, as well as the phenetic relatedness, were evaluated with inter-simple sequence repeat molecular marker (ISSR) using five primers; Ng2.01, Ng2.06, Ng3.01, Ng3.02, and UBC 855, with two other agarwood producing species as outgroup (Aquilaria filaria and Gyrinops decipiens). Amplified bands from all primers showed 55.17% polymorphic bands in G. versteegii. Genetic variation of G. versteegii identified with Nei’s genetic diversity (h value) obtained at 0.218. Clustering analysis from UPGMA dendrograms formed three major clusters. Degree of similarity of G. versteegii based on the dendrograms obtained at 85.9% using SSM method. The results showed close phenetic relatedness between individuals and relatively high genetic variation of G. versteegii, however, imply the need for strictly maintenance of habitat preservation and larger population size.

Published: January 2020

Wood is a natural and highly anisotropic material. Therefore, mechanical characteristics of the material depend on the direction of wood. In this paper, we propose to describe the transfer of the water inside the wood in two dimensions by immersing the sample in liquid water. The potential which drives the transport of water through the wood is controlled by the diffusion transient process.  A model based on a numerical finite difference method has been found to follow the absorption process of water above the fibers saturation point of two-dimensions.
The community economies of Esch-sur-Alzette: rereading the economy of Luxembourg
Authors: Taylor Aiken Gerald , Schulz Christian , Schmid Benedikt
Published: January 2020

This article outlines the community economies of Esch-sur-Alzette, the ‘second city’ of Luxembourg. ‘Community economies’ – an approach outlined by J.K. Gibson-Graham – draws attention to alternative narratives of economic development and the representation of economic identity. Despite (the Grand Duchy of) Luxembourg’s reputation as a European Union centre, with substantial finance and tax activity, Esch-sur-Alzette is a post-industrial and multilingual melting pot. The alternative narrative here is of the multiple community-based organisations and movements in Esch-sur-Alzette: an energy cooperative, urban gardening, an upcycling clothing factory, a local food shop and restaurant, and vibrant civil society discussions and interventions in (inter)national politics. Civil society, while central to both understandings of grassroots environmental action and the community economies framework of Gibson-Graham, takes on quite a different flavour in Luxembourg. This article then takes the case of Luxembourg to reread the relationship of the state to the so-called third sector, in doing so defending the political possibilities of community economies.
Feminist responses to sexual harassment in academia: voice, solidarity and resistance through online activism
Authors: Anitha Sundari , Marine Susan , Lewis Ruth
Published: January 2020

This paper takes as its starting point the compilation and circulation online of a list naming alleged sexual harassers in Indian academia in order to examine broader questions about the nature of online activism to address gender-based violence. Set against the historical silencing of women who speak about violence as well as institutional mechanisms to address this issue through due process, we examine the meaning, impact and limitations of this list, which generated considerable discord and debate within feminists in India. In doing so, we consider the place of these new forms of collective actions and expressions of solidarity within the broader feminist campaigns to resist violence.

Published: January 2020

We developed a modified photonic Doppler velocimetry (PDV) configuration which possesses the ability to record wide-range velocity information to evaluate composite material fracture behavior. With the laminate and tunnel design of a fragment generator, the controllable parameters such as fragment size and applied voltage can provide the flexibility for dynamic evaluation under different momentum conditions. We obtained velocity profiles using continuous wavelet transforms and by using our proposed velocity line tracing algorithm. Simulated heterodyne signals and surface morphology of fractures were examined to verify the heterodyne signals. We observed that the obtained tunnel-end velocity of the fragment generator was proportional to the applied voltage.
General method for complex-wave fields registration with high fidelity
Authors: Zhao Jie , Zhang Fucai , Wang Dayong , Zhu Weimin
Published: January 2020

In the field of optical imaging, the image registration method could be applied to realize a large field of view along with high resolution. The traditional image registration methods are mostly conceived for intensity images and might fail for complex-valued images. Especially, those methods do not account for the random phase offset associated with phase. In this paper, we proposed a general method for complex-wave field registration. A similar procedure has been proposed for the reconstruction of the ptychographic dataset, but here is modified for the registration of general wave fields. The method can efficiently separate the illumination and object function, refine the positions of each wavefront, and thus provide a stitched wide-field object wave with high fidelity. Simulation and experimental results applied to register the wave fields obtained from digital holographic microscopy are given to verify the feasibility of the method. This method would have potential applications in large-field high-resolution microscopy, adaptive imaging, remote sensing and the measurement of structured optical fields.
Coupled approach for radiometric calibration and parameter retrieval to improve SPM estimations in turbid inland/coastal waters
Authors: Zhou Q. , Li J. , Tian L. , Song Q. , Wei A.
Published: January 2020

High-precision radiometric calibration (RC) coefficients are required to retrieve reliable water quality parameter products in turbid inland/coastal waters. However, unreliable RC coefficients when satellite sensors lack accurate and in-time RC may lead to pronounced uncertainties in the products through error propagation. To address this issue, a novel approach for estimating water quality parameters, taking suspended particulate matter (SPM) as a case, was proposed by coupling the procedures of RC and SPM model development. The coupled models were established using digital numbers (DNs) from target sensors and “in-situ” SPM measurements from concurrent well-calibrated reference sensors, with the RC coefficients introduced as unknown model parameters. The approach was tested and validated in varied Chinese inland/coastal regions, including the Hongze lake (HL), Taihu lake (TL), and Hangzhou bay (HB). The results show: (1) the DN-based SPM models can achieve a degree of accuracy comparable to reflectance-based SPM models with determination coefficients (R2) of 0.94, 0.92, and 0.72, and root-mean-square errors (RMSE) of 7.02 mg/L, 15.73 mg/L, and 619.2 mg/L for the HL, TL, and HB, respectively, and the biases less than 3% between the derived and official gain RC coefficients; (2) the uncertainty of SPM products increases exponentially as the RC uncertainty increases for exponential reflectance-based SPM models; (3) the DN-based SPM models are less sensitive to the uncertainties of atmospheric correction and RC coefficients, while the reflectance-based models suffer deeply. This study provides encouraging results to the improvement of SPM retrieval using the DN-based models by coupling RC and SPM retrieving processes, especially for sensors without precise RC coefficients.

Authors: Roth Gian-Luca , Rung Stefan , Esen Cemal , Hellmann Ralf
Published: January 2020

In this contribution, we report on the generation of internal microchannels with basically unlimited channel length inside of PMMA bulk material by femtosecond laser. A precisely controllable and stable circular channel cross section is obtained by using a spatial light modulator to compensate the writing depth depending spherical aberration. Furthermore, the generation of a rotatable elliptical input beam by adaptive optics ensures a fitting of the beam shaping to the writing direction. In this study, we report on both, the effect of the ellipticity of the input beam and the effect of a correction of the spherical aberration on the circularity of the resulting internal microchannels. Moreover, we demonstrate the application of this writing technique by creating microfluidic testing structures inside of a transparent standard polymer.

Published: January 2020

Gallium oxide (Ga2O3) has been studied as one of the most promising wide bandgap semiconductors during the past decade. Here, we prepared high quality β-Ga2O3 films by pulsed laser deposition. β-Ga2O3 films of different thicknesses were achieved and their crystal properties were comprehensively studied. As thickness increases, grain size and surface roughness are both increased. Based on these β-Ga2O3 films, a series of ultraviolet (UV) photodetectors with interdigital electrodes structure were prepared. These devices embrace an ultralow dark current of 100 fA, and high photocurrent on/off ratio of 10E8 under UV light illumination. The photoresponse time is 4 ms which is faster than most of previous works. This work paves the way for the potential application of Ga2O3 in the field of UV detection.

Published: January 2020

The development of a broadly and accurately tunable single-frequency mid-infrared laser source and its application to a sensitive laser absorption detection method are described. Photo-thermal interferometric spectroscopy is employed as a phase-sensitive method to detect the minute refractive index change caused by the heating of a gas under laser radiation. A separate probe beam allows for the spectrally-interesting mid-infrared region to be examined whilst utilizing low cost, high detectivity photodetectors in the visible/near-infrared region. We also describe the implementation of a Sagnac interferometer to minimize the effects of environmental perturbation and provide inherent passive stability. A continuous-wave ring-cavity pump-enhanced OPO has been developed to provide excitation light from 3–4 µm at 140 mW with the ability to mode-hop tune continuously over 90 cm−1 in 0.07 cm−1 steps. Complementary use of both detection apparatus and excitation source has allowed for presence of ethane to be detected down to 200 parts per billion.

Authors: Turan Deniz , Yardimci Nezih Tolga , Jarrahi Mona
Published: January 2020

We present a photoconductive terahertz detector operating at the 1 µm wavelength range at which high-power and compact Ytterbium-doped femtosecond fiber lasers are available. The detector utilizes an array of plasmonic nanoantennas to provide sub-picosecond transit time for the majority of photo-generated carriers to enable high-sensitivity terahertz detection without using a short-carrier-lifetime substrate. By using a high-mobility semiconductor substrate and preventing photocarrier recombination, the presented detector offers significantly higher sensitivity levels compared with previously demonstrated broadband photoconductive terahertz detectors operating at the 1 µm wavelength range. We demonstrate pulsed terahertz detection over a 4 THz bandwidth with a record-high signal-to-noise ratio of 95 dB at an average terahertz radiation power of 6.8 µW, when using an optical pump power of 30 mW.
Two broad absorption bands in infrared atmosphere transparent windows by trapezoid multilayered grating
Authors: Li Yulian , Li Linzhi , Wang Fang , Ge Haonan , Xie Runzhang , An Bowen
Published: January 2020

We proposed a metamaterial absorber composed of an array of trapezoid multilayered grating Au and InP on top of an opaque substrate, which covers two atmosphere-transparent-window bands with appropriate modulation of geometric parameters. The absorption higher than 0.8 is from 3.5 to 4.8 µm and 7 to 14.3 µm. From the effective medium theory and dispersion relation, the reason of the broad-band absorption is the first and third order slow light effect respectively, which is verified by the electromagnetic and thermal loss distribution further. This absorber may greatly promote the practical application of absorbers in double-color infrared imaging, detecting, infrared stealth and sub-ambient passive radiative cooling by thermal emitting.
Analysis of phenolic compounds and immunomodulatory activity of areca nut extract from Aceh, Indonesia, against Staphylococcus aureus infection in Sprague-Dawley rats
Authors: Sari Liza Meutia , Hakim Rachmi Fanani , Mubarak Zaki , Andriyanto Andriyanto
Published: January 2020

Aim: The aim of the study was to investigate the immunomodulatory activity of areca nut extract. The phytochemical content and phenolic composition of the extract were also determined.

Materials and Methods: An extract of areca nut was prepared using 96% ethanol and subsequently screened for phytochemical content using a high-performance liquid chromatography (HPLC) method. The immunomodulatory activity of the extract was tested in 35 Sprague-Dawley rats, divided into four groups: One control group and three experimental groups in which the rats received 500, 1000, or 1500 mg/kg of oral areca nut extract biweekly (BW). The extract was orally administered 14 days before the intraperitoneal challenge with Staphylococcus aureus (1×108 CFU/mL). On the 14th day of the experiment, rats in all the four groups were sacrificed. Measurement of the levels of red blood cells, hematocrit (Hct), hemoglobin (Hb), white blood cells (WBCs), lymphocytes, monocytes, neutrophils, basophils, eosinophil, and macrophages were recorded. The activities of serum glutamate oxalate transaminase, serum glutamate pyruvate transaminase, urea, and creatinine were also determined.

Results: Areca nut was found to contain an alkaloid, tannin, and flavonoid compounds. HPLC analysis revealed the presence of catechin as the major compound along with quercetin. Administration of areca nut extract in rats infected with S. aureus produced a significant increase in the concentration of WBC but did not affect Hct, Hb, and other cell types. Among the different doses tested, 1000 mg/kg BW was found to be most effective in cellular immunity models. No harmful effects on the liver and kidney functions were observed.

Conclusion: The antioxidant activity of areca nut might be attributed to the presence of catechin and quercetin. Administration of areca nut extract increased the number of WBCs and improved the activity and capacity of macrophages significantly in rats infected with S. aureus.
Large Cameron Ulcer Bleed

Published: January 2020

Cameron ulcers usually present with chronic obscure gastrointestinal bleeding. Few cases of life-threatening bleeding have been reported. We hereby present an elderly man who presented with upper gastrointestinal bleeding associated with hemodynamic instability because of a large cratered Cameron ulcer. This ulcer contained a large pseudoaneurysm, and endoscopic therapy was deemed unsafe. The patient had a recurrence of his bleeding, necessitating intervention by our interventional radiology colleagues and then surgical intervention for definitive therapy. This case is important because it familiarizes gastroenterologists with the endoscopic appearance of huge Cameron ulcers and therapeutic options to control hemostasis. It also stresses the importance of a multidisciplinary team approach to ensure the best outcomes for patients.

Published: January 2020

Rare condition characterized by an intensive and excessive breast enlargement is known as gigantomastia. Gestational gigantomastia manifests during pregnancy and could represent a life-threatening condition for both the mother and the fetus, therefore the risk of spontaneous abortion complicates the choice of treatment approach. We present a clinical case of a patient requesting medical assistance with a progressive breast growth. The onset occurred on the 5th week of gestation and, subsequently, was aggravated by distal tissue necrosis. The ambiguity of treatment approach in such situation is based on, on the one hand, the insecurity of watch-and-wait approach due to the high risk of septic complications and, on the other hand, the increasing danger of fetal loss in the case of surgical treatment during the first trimester of pregnancy. After an adequate assessment of mothers health state, a decision was made towards the wait-and-see tactic until the complete formation of the placental barrier. A total bilateral mastectomy was performed at the 19th week of pregnancy, with a favorable outcome for the patient and her child. This case emphasizes the significance of an individual, interdisciplinary approach to the choice of management for patients with this pathology.

Argumentamos ser necessário ampliar o olhar sobre o trabalho na universidade, de forma a considerar seus múltiplos agentes e sua dimensão global e multifacetada, sob a égide da degradação, desgaste e falta de sentido. Apontamos para situações nas quais distintas formas de sofrimento se desdobram em estresse, distúrbios de ansiedade ou depressão.  Concluímos que tais desdobramentos podem provocar, especialmente nos estudantes, situações-limite de psychache, desalento e desesperança, de forma a implicar em  tentativas ou atos suicidas que necessitam ser prevenidos e melhor investigados.
Effect of the combination of Education level and Business location on product quality: The Case Study of Arc Welding in Small Scale Metalworking Enterprises in Kenya
Authors: Ondieki Charles M. M.
Published: January 2020

The quality of products from the micro and small enterprise sector is affected by both the entrepreneur’s and enterprise’s attributes. This paper presents and discusses findings of a study that was designed to investigate experimentally the relationship between the quality of arc in the Small Scale Metalwork sub-sector and the combined effect of the artisan’s education level and business location. A total of 36 artisans with secondary education and 36 artisans with primary education consisting of formally (35) and informally (37) trained artisans from urban (29) and rural (43) areas participated in the evaluation. A mild steel product was fabricated by each participating artisan, assessed and scores awarded based on the quality of arc welding. The analysis of variance (ANOVA) was used to show any variation in the quality of arc welding; comparisons of means using the Least Significant Difference (LSD) at the alpha level of 5% were done to determine which pairs of artisans affected quality significantly. The study found out that artisans with secondary education performed better than those with primary education. The study also found out that artisans from urban areas performed better those from rural areas. The findings of this study provide evidence that higher level of education and urban location of business can improve product quality.

This paper examined the intervening variables affecting the mobilization of savings of Staff owned Cooperative Societies in Nasarawa State Public Institutions and their effects on the savings mobilization. It was a survey research that focused on the Naspoly Staff Cooperative Society, Nasarawa State Polytechnic Lafia, Nasarawa State Nigeria. Questionnaire was administered to a randomly sampled 250 members from the 380 registered members as at December 2018, with the view to confirming that the following variables (family size, income level, number of children in school and market situation) affects savings mobilization of staff owned cooperative societies in public institutions in Nasarawa State.  Data collected were analyzed using descriptive statistics and The Pearson Product Moment Correlation. Findings from results of the study showed that, the identified variables intervenes in savings activities of staff members, it actually hampered the society’s efforts in mobilizing savings.
