Published: May 2021

Abstract
In spite of the importance of woman lecturer perception of work-family conflict and its influence on organizational commitment, job satisfaction can be used as a mediator, this study aims to examine an indirect influence of work-family conflict on female lecturers’ commitment to their organization. This study employed a survey of 91 female lecturers of Nahdlatul Ulama University of Surabaya. In exploring the complex relationship among work family conflicts (i.e. work interferes family and family interferes work), job satisfaction and organizational commitment, the researchers utilized partial least square to overcome the weaknesses of linear regression models. In this research, we found that female lecturers’ perception of work-family conflict was negatively related to their level of organizational commitment. In addition, perception of work interfere family and family interfere work had an indirect impact on the female lecturers’ organizational commitment through job satisfaction. This study contributed to the literature by examining organizational commitment in light of female lecturers’ perception of work family conflict and job satisfaction using partial least square to explore the complex relationship among organizational factors.

Abstract
Fractions are one of the mathematics topics that have been taught starting in grade two on elementary school. For kids, understanding a fraction is not so simple, especially in sorting fractions, ascending or descending. A fraction consists of two part numerator and denominator. A common technique frequently used in sorting some fractions is making the denominators of those fractions are the same, and compare the numerator which on is greater or less than other. This technique requires a long and slightly complicated process. The researchers will study a new technique for sorting fractions, namely the Graph Area Shading (GAS) technique. By a graph, we mean a set of vertices together with edges representing a specific relation. The simplest graphs are path and cycle. We will use some other graphs such as wheel, friendship and fan graphs. This technique is considered to be pretty much easier for kids to sort the fractions.

Abstract
Elaborating Science, Technology, Engineering, and Mathematics in learning activities is now getting important, especially to improve the STEM literacy of the students of school age or higher. For the higher age students, elaborating the STEM education should encourage them to raise their higher-order thinking skills. Thus the implementation of research-based learning together with a STEM education will be a good model in designing learning activities. Meanwhile, in STEM education, integrating some social real-life problems becomes the main issue. In this study, we will focus on the preservation process of food or meat. The biggest problem, in this case, some preservatives, however, contain harmful substances, like formalin and borax. Under STEM education, we will guide students in research-based learning activities to use chitosan made from shrimp skin to be a natural preservative substance. The objective of this study is to design the research-based learning activities under the STEM approach on the use of chitosan preservatives for processed meat.

Published: May 2021

Abstract
Concrete has high compression strength but low tensile strength. Therefore fibers are added to enhance the tensile strength. South Kalimantan is one of Indonesia’s largest wetlands, and the banana tree is common in this area. After harvesting, they are accumulated or be burned, causing pollution. Utilizing banana tree waste as fiber in the concrete minimizes it. This paper investigated the effect of banana fiber length and percentage of fiber by volume fraction on the compressive of mortar, tensile, and compressive concrete strength. The correlation between the compressive and tensile strength was further established. The percentage of fiber used in this research was 0.1%, 0.2%, and 0.3%, and the length of the fiber was 7cm and 15cm. The results showed that the addition of banana fiber significantly improved the mechanical properties of mortar and concrete. The compressive strength of mortar with a fiber length of 7cm was higher than 15cm. The higher percentage of fiber causes the lower compressive strength of mortar. The compressive strength of fiber-reinforced concrete was 27.9 MPa, and the ordinary concrete was only 17.91 MPa. The tensile strength of fiber-reinforced concrete was 6.96 MPa, while the ordinary concrete was just 1.93 MPa.

AbstractStyrax sumatrana, native to Sumatra island, Indonesia, is distinctive for its production of benzoin resin. The resin is used for medicinal treatments and commercially valuable. Fungal endophytes are known to produce various bioactive metabolites and may contribute to host resin production or properties. However, the diversity of culturable endophytic fungi associated withS. sumatranawere still underexplored. This study was conducted to examine the distribution and diversity of culturable endophytic fungi associated with tree parts; bark, stem, and leaves ofS. sumatrana. A total of 31 endophytic fungi isolates were obtained fromS. sumatranagrown in North Sumatera Province, from which 10 genera and 17 species were identified by internal transcribed spacer (ITS) sequence analyses. Among 31 isolates,Fusarium, Phyllostica, NeopestalotiopsisandPestaliopsiswere repeatedly isolated. The species richness S (10), Margalef index D’ (3.323), Shannon–Wiener index H’ (1.587), and Simpson diversity index Ds (0.756) and low dominant index λ (0.244) of endophytic fungi in the bark ofS. sumatranaindicated its high diversity in comparison to other parts of the tree. This finding provides a knowledge of the diversity and organ-type-specificity of endophytic fungal that could be used for biotechnological application in the future.

Abstract
Wana Patra Lestari (WPL) is a remaining forest in the center of Balikpapan City. It is located in the working area of PT Pertamina Refinery Unit (RU) V Balikpapan. Besides having cultural and historical value, the existence of the WPL area also has environmental service value as a habitat for birds and mammals. This study aims to analyze the diversity of bird and mammal species in the WPL area. We collected all related bird record by using a combination of point count and mist-netting methods. Furthermore, mammal was sampled by using a combination of line transect, live-trapping, camera-trapping, and also mist-netting survey. The results showed that in the WPL area 17 species of birds and 6 species of mammals were identified. There are 14 species of birds and 2 species of mammals added from previous studies. Of all the identified species, there is only one protected species in Indonesia, namely Elang Bondol (Haliastur indus). Periodic monitoring is needed to find out more about population dynamics and diversity of wildlife in the WPL.

Abstract
Pot experiment was conducted to observe the effect of frass (insect feces) from Black Soldier Fly larvae (BSFL) as soil amendments at different application rates in comparation with other organic fertilizers on Pakchoi (Brassica rapa L). The experimental design was completely random with seven treatments, namely compost, compost+LOB (liquid organic biofertilizer), 5%, 10%, and 15% BSF frass, chemical fertilizer (NPK, equivalent to 10 kg/ha), and soil as a control. After 35 days planting, the result showed that Pakchoi cultivated with compost+LOB, compost, and BSF frass produced the highest biomass compared to control and NPK treatment significantly. The highest total plant weight was achieved in the treatment of Compost+LOB (24.4 gr), followed by 10% BSF frass (23.3 gr), compost (21.8 gr), 15% BSF frass (20.7 gr), 5% BSF frass (19,8 gr), NPK (1.3 gr ) and control soil (0.9 gr). While the chlorophyll content was not significantly different between all treatments, the application of BSF frass tended to be higher but with curly leaf symptoms than other treatments. The population of P solubilizing bacteria and the activity of PME-ase enzyme in soil were also higher in the treatment of compost, compost+LOB, and BSF frass compared to control and NPK treatment.

AbstractMillipedeCylindroiulussp. is well known as decomposer invertebrate. Its ability to break down organic waste is related to microbiota in their gut. Gut bacteria are known to be able to produce enzymes which have the potential as an organic waste decomposing agent. This study aimed to obtain potential bacteria in producing hydrolytic enzymes from the gut ofCylindroiulussp. and to evaluate their enzymatic activities. Gut bacteria were isolated fromCylindroiulussp. living in the household organic solid waste composter. Furthermore, isolated bacteria were analyzed quantitatively for their amylase, cellulase, protease, whereas qualitatively for lipase activities using semi-selective media. In this research, nine bacterial isolates were obtained. Three isolates namely EKG A1, EKG A4, and EKG A5 were able to produce all of the enzymes and identified asBacillusgenera. The highest index of enzyme activity in amylase, cellulase, and protease were 2.13 ± 0.08, 2.56 ± 0.03, 4.49 ± 0.17, respectively.Cylindroiulussp. gut bacteria were prospectively applied to decompose organic solid waste.

Abstract
We present population structure analysis of two differed Ongole grade cattle strains in Indonesia i.e., common Ongole grade (PO) and Kebumen Ongole grade (PO Kebumen). The aim of this study was to identify the genomic characteristic of both PO and PO Kebumen cattle strains. In this study, genotyping method of 15 PO and 25 PO Kebumen was carried out using an Illumina BovineSNP50 Bead Chip. In order to deeper analyses, we used additional 50K SNP data of 20 PO, 20 Nellore, 20 Brahman, 20 Simmental, and 20 Limousin that freely available in the data repositories. An estimation of the genetic population study was carried out using following approaches: pairwise fixation indices, heterozygosity and Nei’s standard genetic distance, and ancestral based admixture. These analyses revealed a B. taurus influence in PO but none in PO Kebumen. Furthermore, we also identified the close admixture of PO Kebumen to Nellore. Since Nellore was originated from Ongole cattle, we presume the PO Kebumen is the maintained Pure Ongole Breed in Indonesia.

Using in vitro technique for drought, heat, and combined drought-heat assay in potatoes
Authors: Handayani T , Watanabe K N 
Published: May 2021

Abstract
Drought and heat stresses are the significant abiotic stresses threatening the food crops, including potato. The in vitro technique is promising to conduct an abiotic stress assay. The assay of drought, heat, and combined drought-heat stress was conducted by using five potato lines. Polyethylene glycol (PEG) 8000 (25%) was used to induce drought stress. Heat stress was obtained by growing the plantlets at 35°C. Whereas placing the plantlets cultured in the media containing PEG 8000 (25%) at 35°C was applied to generate combined drought-heat stress. The results showed that four hours of abiotic treatments had no effect on growth of potato plantlets. The results showed that potato lines gave different responses to drought and combined drought-heat stress. Potato line 87HW13.7 wilted 8 hours after drought and combined drought-heat treatments, which became more severe by the time and died after 48 hours on combined drought-heat stress. Potato line 84.194.30 showed the wilting symptom after 24 hours due to drought stress and combined drought-heat stress and performed less wilting among five potato lines. The in vitro technique could differentiate the response of different potato lines to abiotic stress; therefore, this method would help the abiotic stress assay in potatoes.

Abstract
Hybridization is meant to combine good characters to produce new individuals. This study aims to understand the genetic relationship of parents and progeny derived from crossed pollination. The study was conducted in the laboratory and greenhouse of the Indonesian of Spice and Medicinal Crops Research Institute. The plant materials used were female (N2) and male (LDL) parents, F1, F2, and their backcrosses. Morphological characters were observed in young plants grown in pots. Molecular analysis was performed with RAPD. Morphological and molecular data were processed with PBSTAT. The coefficient of diversity for the genetic relationship of parents and progeny derived from crossed pollination (N2 x LDL) based on morphology ranged from 12-50% or Similarity of 50-88%. The dissimilarity between parents (N2 and LDL) and both hybrids (LH 4-5 and LH 4-5-5) was 32%. The genetic relationships based on RAPD obtained diversity coefficients ranging from 40-80% or Similarity of 20-60%. The dissimilarity between parents (N2 and LDL) with both hybrids (LH 4-5 and LH 4-5-5) was 46%. Similarity-based on morphological characters is higher than on RAPD markers.

Published: May 2021

Abstract
A characterization of the sarcoplasmic protein in the meat had been investigated. The method that was utilized in this study was SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) which played a role in analyzing the molecular weight of the meat protein. The characterization of the molecular weight depended on the concentration of acrylamide gel that has been used. The result reported that using of 10% acrylamide gel showed difference of the molecular weight characterization from the sarcoplasmic protein. The difference of protein in the meat is on sarcoplasmic proteins. Protein with molecular weights of 50.8 kDa was not found in pork. Therefore, this molecular weight of the protein can potentially serve as a key for differentiating pork and other meats.

AbstractGibberellins are growth regulators that can increase seedling germination of true shallot seed (TSS). This study aims to determine the effect of TSS soaking duration in gibberellins solution on germination and growth of two TSS varieties. The study was conducted from May to June 2020 in Kotarindau Village, Dolo SubDistrict, Sigi Regency. The study used Factorial Randomized Block Design with 2 factors, each repeated 5 times. The first factor is Variety, consisting of Trisula and Lokananta. The second factor is the Seed Soaking Duration (T), consisting of 4 levels which are No Gibberellin Soaking, 2 hours Soaking, 4 hours Soaking, and 6 hours Soaking. To determine the effect of treatment, analysis of variance was carried out, continued with Duncan’s Multiple Range Test (DMRT) at 5% when the results of variance showed significant differences. The results showed that varieties and soaking duration of TSS in gibberellins solution treatments have significant effect on the growth of TSS. The highest number of plant height and number of leaves was obtained in the treatment of Lokananta varieties with 6 hours soaking duration, but not significantly different from the treatment of the Trisula varieties with 2 hours soaking duration in the number of leaves parameters.
