AbstractA detailed chronostratigraphic framework established by the mapping of tephra key beds and application of oxygen isotopic data allows assessment of the synchroneity and diachroneity of depositional systems formed in coastal and deep-water environments. This framework also allows estimation of the timing of active delivery of coarse-grained sediments beyond the shelf margin in relation to relative sea-level changes. The depositional processes of deep-water massive sandstones (DWMSs) are still enigmatic; their formation is a result of active delivery of sands in association with the supply of organic carbon into deep-water environments. DWMSs are also important as reservoirs for hydrocarbon explorations. This study investigated the origins of DWMSs in the upper Umegase, Kokumoto, and Chonan formations (in ascending order) of the Pleistocene Kazusa Group on the Boso Peninsula, central Japan. Each formation contains several packets of DWMSs that are interpreted to have formed in response to the progradation of gravelly shelf-margin deltas or fan deltas during the falling and lowstand stages of relative sea-level changes controlled primarily by glacioeustasy. The development of DWMSs and associated sandstone beds is interpreted to have been induced by hyperpycnal flows, in association with sediment gravity flows that were initiated by breaching and/or collapse of sandy substrates on the shelf-margin deltas or fan deltas. The timings of the initial and final deposition of the packets vary within and between the formations, and are considered to have been controlled by the interaction between allogenic and autogenic processes operating in the gravelly shelf-margin deltas or fan deltas. A muddy horizon that contains the Lower–Middle Pleistocene Subseries boundary (the base of the Chibanian Stage) in the Kokumoto Formation is also underlain and overlain by the packets and represents a deposit formed in a condensed section in an upper slope environment. This depositional setting may have favored the development of the Global Boundary Stratotype Section and Point (GSSP) for the Lower–Middle Pleistocene Subseries boundary in the formation.
Another way of “amusing ourselves to death”? Experience, ideological fantasy, and labor control in variety entertainment production
Authors: Jia Wenjuan , Zhong Kaiou 
Published: August 2020

AbstractCompared with traditional industries, new changes have taken place in the labor process and manufacturing consent in cultural and creative industries. In entertainment labor, managers transform high-intensity labor into pleasant entertainment through relational work, emotional work, and sentimental work. In contrast to traditional industries, labor control in entertainment does not rely on organizational institutions or economic incentives but is based on supplemental cultural factors, such as relationships, emotion, and sentiment. At the same time, the logic of ideological operation behind manufacturing the consent of laborers is no longer according to the traditional Marxist-Althusserian interpretation in which managers shape a particular idea through the control of the labor process while concealing the real labor–capital relation with a false consciousness. It becomes a case of a Lacanian–Zizekist description: the laborer enters a realistic fantasy through specific experience and pursues hisplus-de-jouirin ideological reality. In the end, the laborers devote their body and soul to work.

Abstract. Rached-Kanouni M, Hani I, Bousba R, Beldjazia A, Khammar H. 2020. Structural variability of Aleppo pine stands in two forests in northeastern Algeria. Biodiversitas 21: 2848-2853. The layout of the stand can be described as the width of the trees, their reciprocal locations, diametric distinction and height. The goal of this study is to recognize changes in the Pinus halepensis spatial and demographic systems in two Beni Oudjana and Chettaba Forests, located in northeast Algeria. An inventory of trees in these forest formations with P. halepensis dominance was carried out based on dendrometric parameters such as total height, tree diameter at dbh ≥ 5 cm, basal area, total volume, etc., as well as the number of trees in the forest. Tree diameter and height measurements were made on 12 rectangular plots (20 m × 20 m), located in both forests. The results obtained show that the mean stand density, mean diameter, basal area and total volume are higher in Chettaba Forest, the values attributed to these parameters are respectively (422 trees/ha, 27.07 cm, 26, 86 m2, 251.63 m3); while the total height and regeneration rate show significantly higher values in Beni Oudjana Forest (18.97 m, 607 individuals/ha). The structure in diameter and height of the species is bell-shaped to asymmetrically positive with a predominance of small diameter individuals in the Chettaba forest. On the other hand, in the Beni Oudjana Forest, the structure is ‘L’ shaped, showing a predominance of very small diameter individuals. These results indicate that the low regeneration rate of P. halepensis in the Chettaba Forest is due to anthropogenic pressures that favor the degradation of this forest.

Abstract. Simanjuntak R, Yusniar M, Samalukang YM, Boleu FI, Mardiastuti A, Widyasari V, Udin JS. 2020. Short Communication: Egg harvesting and local conservation of Moluccan Scrubfowl (Eulipoa wallacei) in the Maluku Islands, Indonesia. Biodiversitas 21: 3018-3024. This study was conducted at four locations in Central Maluku and North Halmahera, which have been used as nesting ground habitats of the Moluccan Scrubfowl (Eulipoa wallacei), an endemic bird of the Maluku Islands, Indonesia. The objective of this study was to record and analyze the egg harvesting and local conservation of Moluccan Scrubfowl in four locations in the Maluku Islands: Simau, Kao, Haruku, and Kailolo. The results showed that a relatively large number of harvested eggs were found in Simau (Halmahera Island) and Kailolo. In Kailolo, the total number of eggs harvested was 21,707 per year. The local community has the initiative to conserve this bird by establishing local regulations, called sasi. The Haruku community gave a portion of the eggs to Kewang, a customary institution authorized to manage the natural resources, to be hatched semi-naturally around the Kewang House. Likewise, the Salabia youth organization in Simau, together with landowners, developed a semi-natural hatchery for the Moluccan Scrubfowl eggs.

Abstract. Baihaqi ZA, Nurcahyo W, Widiyono I. 2020. Prevalence naturally infected gastrointestinal parasites and complete blood count condition on Wonosobo sheep at Wonosobo District, Central Java, Indonesia. Biodiversitas 21: 3057-3061. The aim of this study was to determine complete blood count of Wonosobo sheep infected with internal parasites on sheep farms in Wonosobo District, Central Java, Indonesia. Fecal and blood samples were taken from 130 female Wonosobo sheep. Fecal samples were individual and the numbers of worm eggs per gram of feces (eggs per gram, EPG) were counted. Complete blood count analyzed with a hematology analyzer machine and total protein were measured with a refractometer. The total average prevalence of gastrointestinal (GI) parasite infections in the Wonosobo sheep are 66.92%. The prevalences of low EPG and high EPG GI parasite infections in female Wonosobo sheep were 19.23% and 47.69%. The gastrointestinal worm species found infecting female Wonosobo sheep in this study were Haemonchus spp., Ostertagia spp., Trichostrongylus spp., Trichuris spp., Bunostomum spp., and Moniezia spp. The most prevalent GI parasites infections in Wonosobo sheep were caused by Haemonchus spp., and the last prevalent ones were caused by Trichuris spp. Mean Corpuscular Volume (MCV), Mean Corpuscular Hb (MCH), Mean Corpuscular Hb Concentration (MCHC), White Blood Cell (WBC), neutrophil, eosinophil, and lymphocyte counts in female Wonosobo sheep with naturally occurring gastrointestinal worms that had EPG > 600 were significantly higher (p < 0.001) than those in sheep that had EPG <600. Hb, Hematocrit (HCT), Red Blood Cell (RBC), and Total Protein (TP) were significantly lower (p < 0.001) in sheep with EPG values >600 than in sheep with EPG <600. Monocyte and basophil values were not significantly different (p > 0.05) between infected sheep with EPG <600 and those with EPG >600. This study shows that gastrointestinal worm infections naturally affect the hematology and blood chemistry of female Wonosobo sheep in Wonosobo district, Central Java, Indonesia.

Abstract. Mulyani A, Darwanto D, Widodo S, Masyuri. 2020. Production efficiency of Inpago Unsoed-1 and Situbagendit rice farming in Central Java, Indonesia. Biodiversitas 12: 3276-3286. Inpago Unsoed-1 rice is a new superior rice variety that is not as familiar as Situbagendit variety for farmers in Indonesia. As one of the new superior rice variety, Inpago Unsoed-1 is expected to improve farm business efficiency so that it can increase farmers' income. This study was conducted to figure out the factors influencing the production of Inpago Unsoed-1 and Situbagendit rice in Province of Central Java, and to recognize the level of technical, allocative and economic efficiencies of Inpago Unsoed-1 and Situbagendit rice farming in Province of Central Java. Research sites included selected regencies in Province of Central Jawa, such as Banyumas, Purbalingga, and Cilacap. Meanwhile, the selected districts were Kalibagor (Banyumas); Kalimanah, Kemangkon, Bukateja, Kutasari, Kaligondang, and Bobotsari (Purbalingga); and Gandrungmangu (Cilacap). Data were collected by direct observation and interviews using semi-structured questionnaire. The sampling technique used non-probability sampling using a purposive sampling method. Data were collected during December 2018-May 2019, 147 farmers were sampled, consisting of 71 and 76 farmers for Inpago Unsoed-1 and Situbagendit, respectively. Data were analyzed by using Cobb-Douglas production function and function of Stochastic Frontier. The results showed that production factors of land acreage (ha) and P fertilizer (kg) positively affected the production of Inpago Unsoed-1 rice, whereas seeds (kg), N fertilizer (kg) and pesticide (l) had negative impact on its production. On Situbagendit rice production, the positive and negative effects were revealed by land acreage (ha) as well as pesticide (l) and N fertilizer (kg), respectively. Technical, economic, and allocative efficiencies on Inpago Unsoed-1 rice farming were 0.75, 0.65, and 0.88, respectively, which were higher than those of Situbagendit, i.e. 0.73, 0.54 and 0.75, respectively.

Abstract. Yulianto D, Batubara IIAS, Nur FM, Rizal S, Siti-Azizah MN, Muchlisin ZA. 2020. Morphometrics and genetics variations of mullets (Pisces: Mugilidae) from Aceh waters, Indonesia. Biodiversitas 21: 3422-3430. Mullets are one of the commercial groups of coastal fish living in Aceh waters, in Indonesia. Presently, there is limited information on the bioecology, especially on the genetics and morphometrics of these fishes. Therefore, the objective of this study is to examine the morphology and genetic variations of Liza macrolepis, Liza tade, and Moolgarda engeli mullets. This study was conducted from January 2018 to July 2019 in four locations along the northern and eastern coasts of Aceh. Data were obtained by measuring the morphometrics of a total of 180 samples of the species in equal ratios. The data were analyzed using the ANOVA and Discriminate function analysis (DFA). The ANOVA test showed that at least 75% of characters are not significantly different among the mullets. Meanwhile, the discriminant function analysis produces the two functions with Eigenvalue of 0.627 and 0.107 with 85.5% and 17.2% total variants, respectively. Function 1 discriminates the mullet samples into two groups; the first was L. tade, and the second belonged to L. macrolepis and M. engeli. In addition, a total of 18 samples of mullets consisting of 8 samples of the L. macrolepis, 2 samples of the L tade, and 8 samples of the M. engeli were successfully amplified from the 5' region of the mitochondrial cytochrome oxidase subunit I (COX1) gene using a pair of primers (Fish F1 and Fish R1). Furthermore, a total of 7 haplotype sequences were produced from the ingroup where L. tade has one haplotype, L. macrolepis and M. engeli had three haplotypes, respectively. The genetic distance analysis showed that the interspecific distance was 0.38% and intraspecific was 8.2%. Therefore, the COI gene successfully discriminated against the mullet into three valid species.

Assessment of soil quality parameters and yield of rice cultivars in Melaleuca cajuputi agroforestry system. Biodiversitas 21: 3463-3470. Interactions between rice cultivars and soil quality parameters rises problems in the attempt of increasing rice yield. The objective of this study was to assess soil quality parameters that affect the yield of 15 rice cultivars in an agroforestry system of ‘kayu putih’ (Melaleuca cajuputi) situated in Menggoran forest, Yogyakarta, Indonesia which have three soil types namely Lithic Haplusterts, Ustic Epiaquerts, and Vertic Haplustalfs. The observation was conducted on 21 soil quality parameters and yield of rice cultivars. The data were analyzed by using ANOVA, factor analysis, and stepwise regression. The highest yield of rice per hectare was attained by GM 28 in Ustic Epiaquerts with 6.493 tons ha-1, while Situ Patenggang and GM 28 in Vertic Haplustalfs as high as5.549 and 5.401 tons ha-1, respectively, and Situ Patenggang in Lithic Haplusterts as high as 4.893 tons ha-1. Soil quality parameters that had significant effect on the yield of rice cultivars were Clay, SMC, pH, SOC, N, Mg, Fe, Fg, and Bae. We suggested that rice cultivars recommendations for Lithic Haplusterts, Ustic Epiaquerts, and Vertic Haplustalfs are Situ Patenggang, Situ Patenggang or GM 28, and GM 28, respectively, in addition to fertilization based on limiting factors of each rice cultivars.

Abstract. Tan WA, Teja HS, Stephane. 2020. Ramularia mali strains isolated from petroleum product-contaminated soil are capable to grow on multiple aromatic compounds. Biodiversitas 21: 3590-3595. Aromatic compounds are present as a complex mixture in the environment, some of which are toxic and carcinogenic in humans and animals. In this study, we reported the first instance of arthroconidial yeast growth on more than one aromatic compound. Yeasts were isolated from soil surrounding gas stations and screened for growth on phenol, followed by qualitative growth testing on chlorobenzene, aniline, toluene, 2-nitrotoluene, benzoate, and naphthalene. Pure isolates identity and phylogeny were determined based on the ITS region. All isolates grew on phenol and benzoate, but none grew on naphthalene. Aside from the inability to grow on naphthalene, SR8 grew on other tested aromatics, while SR3 showed similar growth ability except on 2-nitrotoluene. Growth on 2-nitrotoluene was observed for PPS3, PB4, SR1, SR6, and SR8, a phenotype that has yet been reported in yeasts thus far. All isolates shared 99.81-100% similarity and were phylogenetically clustered with the arthroconidial yeast Ramularia mali CBS 129581, despite that some of them were morphologically different and had varying capability to grow on tested aromatics. Therefore, ITS sequences cannot be used to differentiate Ramularia mali up to the strain level. Overall, we demonstrated the diverse potential of yeast strains in reducing aromatic compound contamination.

Abstract. Fatem SM, Djitmau DA, Ungirwalu A, Wanma AO, Simbiak VI, Benu NMH, Tambing J, Murdjoko A. 2020. Species diversity, composition, and heterospecific associations of trees in three altitudinal gradients in Bird's Head Peninsula, Papua, Indonesia. Biodiversitas 21: 3596-3605. The region of Bird's Head Peninsula, West Papua, Indonesia has a high level of vegetation diversity distributed from coastal to mountain areas. Yet, the information regarding this diversity is limited. We studied species diversity, composition, and heterospecific association of trees in three altitudinal gradients in Bird's Head Peninsula to reveal the biotic phenomenon in the region. Systematic random sampling was applied during data collection in three locations representing lower, middle, and upper altitudes of natural tropical forest. We applied diversity indices to investigate taxonomic diversity, importance value index (IVI) to reveal floristic composition and canonical correspondence analysis (CCA) for heterospecific associations. In total, we recorded 30 families, 44 genera, and 66 species in the three locations. There were 20 families in lower area and each 15 families in middle and upper areas while the genera per site were 29 in lower, 20 in the middle, and 18 in the upper. The number of species found in lower, middle, and upper areas was 35 species, 24 species, and 27 species respectively. The research revealed that the taxonomic diversity of trees generally decreases as the elevation increases in terms of family, genera, and species level. The dominant species was also different across elevation gradients in which the dominant tree had a different pattern in the three locations between understory and upperstory. Moreover, the gradient of elevation has shaped the type of tree communities, suggesting interactions and associations among tree species. Of all species recorded, 26 species were listed in IUCN Red List with two species were under data deficient, 20 species were least concern, three species were near threatened, and one species was vulnerable.

Abstract. Partasasmita R, Cahyani NT, Iskandar J. 2020. Local knowledge of the community in Cintaratu Village, Pangandaran, Indonesia on traditional landscapes for sustainable land management. Biodiversitas 21: 3606-3616. Cintaratu, a village in Parigi Sub-district, Pangandaran District, West Java province, Indonesia has various landscapes. The recent developments of the community reflect a shift in values towards the attainment of economic prosperity. However, scaling-up the use of landscapes in this capacity can cause negative impacts. A cultural approach to landscape management can assist the village community in identifying sustainable practices. The purpose of this study was to elucidate the community's knowledge of the variety of traditional landscapes that exist in Cintaratu Village and the historical influence on variations in the landscapes. The qualitative method was applied in this study. The result of the study showed that some landscapes, i.e., leuweung karamat (sacred forest), kebon (garden), sawah (rice field), astana (grave/ tomb), pamukiman (residential area), pekarangan (homegarden), walungan (river), solokan (small river), tampian (bathing and washing place for residents), and balong (fish pond) are documented in Cintaratu Village. On the basis of ecological history, it has been revealed that village community’s behaviors have changed various landscapes in Cintaratu Village. Conservation efforts carried out by the people themselves towards the traditional landscapes are usually associated with a customary prohibition or pamali that develops in the village community. The local people of Cintaratu recognize various landscapes that can be classified as natural and cultural landscapes. Based on the information provided by informants, the village landscape changes can be traced from the 1780s to 2019. The history of these landscape changes is the result of various factors, including an increase in population density, the implementation of government policies, and market economic development in the village.
Short Communication: Updated tabular key and improved browser-based interactive key to species of Pratylenchus Filipjev (Nematoda: Pratylenchidae)

Abstract. Gafur A. 2020. Short Communication: Updated tabular key and improved browser-based interactive key to species of Pratylenchus Filipjev (Nematoda: Pratylenchidae). Biodiversitas 21: 3780-3785. Pratylenchus is the genus of plant-parasitic nematodes that attack many crop plants and cause significant economic losses worldwide. Attempts have been made to control the parasitic nematodes. However, incorrect identification of species has hindered biological studies on the nematodes and has led to improper and inefficient control measures. To facilitate identification of Pratylenchus species, a prototype of a cross-platform, browser-based computer-assisted identification key for species of Pratylenchus has been developed, based on the pre-existing tabular key. This paper described updates and improvements that have been made to enhance the performance of the prototype key. Updates on the tabular key, which the browser-based key was based on, were made primarily to incorporate all-new species that have been subsequently published and new data from further reports of existing species. Illustrations of characters and character states were added to the key to help users decide which character states best correspond to their specimens. Drawings of each species were also given to provide general ideas on how the species look like. The user interface has been revised in which species name(s) relevant to selected character state(s) was listed, instead of highlighted from a lengthy full list.
