Published: July 2020

AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh pemanfaatan biogas terhadap kesejahteraan keluarga peternak sapi perah di Kecamatan Mojosongo. Metode penelitian yang digunakan dalam penelitian ini adalah metode deskriptif. Penelitian dilakukan di Kecamatan Mojosongo Kabupaten Boyolali Provinsi Jawa. Populasi dalam penelitian ini adalah seluruh pengguna biogas yang terdapat di Kecamatan Mojosongo berjumlah 30 peternak, sehingga seluruh populasi dijadikan sampel. Teknik pengambilan data menggunakan angket berupa kuesioner tetutup. Dalam penelitian ini, variabel X adalah pemanfaatan biogas dan variabel Y adalah kesejahteraan keluarga peternak. Instrumen yang digunakan dilakukan pengujian terlebih dahulu berupa uji validitas dan reliabilitas data melalui metode Corrected-Item-Total Correlation, dapat disimpulkan bahwa instrumen valid dan reliabel. Selanjutnya dilakukan uji normalitas menggunakan uji Shapiro-wilk, dari hasil perhitungan variabel X diperoleh Sig = 0,055 dan variabel Y diperoleh Sig = 0,101, sehingga kedua variabel memiliki data berdistribusi normal. Dilanjutkan dengan uji linieritas, diperoleh Sig = 0,029, maka dapat disimpulkan kedua variabel memiliki hubungan yang linier. Data dianalisis menggunakan teknik analisis regresi, yaitu suatu proses memperkirakan secara sistematis tentang apa yang paling mungkin terjadi di masa yang akan datang berdasarkan informasi masa lalu dan sekarang yang dimiliki agar kesalahannya dapat diperkecil (Riduwan, 2007: 147).Hasil pengujian hipotesis menggunakan metode Regresi Linier Sederhana. Diperoleh nilai persamaan Ŷ = 48,161 + 1,980 X, berarti terjadi hubungan positif antara pemanfaatan biogas dengan kesejahteraan keluarga. Pada Keofisien Regresi Sederhana, diperoleh nilai thitung > t tabel (2,134 > 2,048), yang menyatakan H 0 ditolak dan menerima H1, artinya ada pengaruh signifikan. Namun dari hasil perhitungan Koefisien Determinasi didaptkan hasil bahwa pengaruh pemanfaatan biogas terhadap kesejahteraan keluarga sebesar 10,9%, yang didapat dari perhitungan Koefisien Determinasi. Sedangkan 89,1% lainnya dipengaruhi faktor lain yang tidak diteliti dalam penelitian ini. Jadi dapat disimpulkan terdapat pengaruh signifikan antara pemanfaatan biogas dengan kesejahteraan keluarga dengan arah hubungan yang positif, walaupun pengaruhnya sangat kecil. Namun jika semakin banyak pemanfaatan biogas yang dilakukan oleh keluarga peternak maka akan semakin baik kesejahteraan keluarga peternak.

Integrasi Paham Agama: Membangun Kesamaan untuk Menegasikan Perbedaan Telaah Serat Sastra Gending
Authors: Riyadi Muhammad Irfan
Published: July 2020

Islamization in Mataram shows symptoms of transformation of the cultural system of society, from global to local culture, from great culture to little culture; Sultan Agung, the last student of Sunan Kalijaga, played an important role in this task. as the third king of the Mataram, he strongly criticized the Islamization model which did not build local conciusness because it uprooted the cultural roots of the community from where it had grown, which would hinder the process of Islamization and the process of community maturity. For this reason, he formulated his thoughts through allegorical poems in the Sastra Gending Literature text. The purpose of this study is to provide an interpretation of the literary Sastra gending so that an integrative acculturative pattern is found in concocting a phenomenal model of Islamization in the Mataram era. This study was carried out by exploring library data, which will be assembled by utilizing historical research methodology of thought, while analyzing the contents utilizing social hermeneutics. Conclusion This study has 2 things: 1) Serat Sastra Gending contains that’s about personal self-integration and divine integration; 2) According to Sultan Agung, human should understand the essence of religious teachings in a balanced way, it will make human life harmonious and peaceful, not mutually blaming and toppling each other. That is the point of preaching with the pacifique penetration model
Interaksionisme Simbolik Ritual Meron di Indonesia dan Relevansinya dalam al Quran
Authors: Atabik Ahmad
Published: July 2020

This paper examines the cultural traditions of meron in Pati Indonesia. A tradition that is interpreted with respect to the prophet by bringing a cone made from large rengginang. The method used is qualitative research with an ethnographic approach that aims to find out the meaning of each meron symbol. The theory used is Herbert Blumer's symbolic interactionism that narrates three assumptions of symbols, namely meaning as the basis of human action, meaning created from social interaction and meaning modified through reader interpretation. The results of this paper are that the meron tradition has relevance to the teachings of Islam as a form of da'wah. Rengginang as a symbol of gratitude and togetherness, a mosque as a religious symbol and the arrangement of rengginang is a symbol of the levels of Iman, Islam and Ihsan. The relevance of meron to the verses of the Quran, as in the study of QS. al-Baqarah: 260. Rengginang made from rice is hinted at in QS. al-Baqarah: 261 and QS. Al-Fath: 29. While the mosque symbol is strengthened in the QS. At-Taubah: 18-19.

Morphological and physiological characteristics of Vinca at di fferent water stress levels

Vinca (Vinca rosea L.) is one of the important medicinal crops as the sources of raw materials for traditional medicines. Its alkaloid is believed can reduce the risk of cancer, blood tension and diabetes diseases. Recently, vinca is only grown as ornamental plant in the garden, therefore, its cultivation methods is limited, especially its water stress tolerance, lite purpose of this experiment was to study the effect of water stess on the morphological and physiological characteristics of vinca. A pot experiment was conducted in the plastics house of the Research Institute for Spice and Medicinal Crops from November 1997 to March 1998. Factorial experiment consisted two factors and three replications was arranged in a randomized block design. Ihe irst factor consisted of two vinca varieties, those wee white flowers (WFV) and red flowers of vinca (RFV). While 4 different levels of water stress i.e., (I) 100% ield capacity (FC), (2) 80% FC, (3) 60% FC, and (4) 40% FC were used as the second factor. Parameters used for evaluating the effect of teatment consisted of morphological characteristics such as (I) plant height, (2) number of primary branches, (3) number of leaves, (4) leaf area (5) dry weight of stem, (6) dry weight of leaf, (7) dry weight of flowers and (8) dry weight of roots, and physiological characteristics observed including: (I) percentages of opened stomata and (2) free proline content of leaf. Results showed that interaction between varieties and water stress did not significantly affect the morphological nor physiological characteristics. Varieties significantly affected the morphological characteristics (except plant height), however they did not signiicantly affect physiological characteristics. Water stress significantly affected the morphological (except dry weight of roots) and free proline contents. Under 80% FC, vinca produced the highest growth and dry weight of plant however, the plant growth and dry weight wee inhibited under 60 and 40% FC. Under 40% FC, percentages of opened stomata deceased signiicantly. Moeover, proline content in the leaves signiicantly increased by water stess treatments.

The experiment was conducted to study the effect of temperature and host size on the growth and development of Trichogramma sp., a species of parasitoid which attacks Cricula trfenestrata s eggs. The experiment was carried oul in the Pesl laboratory, Dalillro, Bogor. with relative humidity ranged between 60-80%. temperature ranged.between 23-25°C, 26-28°C, and 29-3 l"C. with two kinds of different egg size (big and small). This research was conducted from March lo Sepeniber 2000, to optimize the production (generation) of Trichogramma sp. in the Laboratory. The resuts showed that some of Ihe biological index of Trichogramma sp., changed when it was cultivated in different temperature and host size. Temperature influenced longivity of parasitoid while host size influenced almost all of Ihe biological index. Although it was hardly measured, however the temperature and host size seemed to have mutual support in Influencing 7}"fcAogrximnta biological index. In low temperature, the development of parasitoid was longer than that in high temperature, while parasitoid behaviour in ovipositing was influenced by egg size. On Ihe big size host, parasitoid tended ovipositing all al once, while thai on small host ovipositing was done one by one. Ihe average of Trichogramma generation on big host was 42.1 ± 17.1 with sex ratio 1 8.8 I , while thai on small host was 73.3 ± 1 3.2 with sex ratio 6.71 I , where female was plcnticr than male. By using Birch methods, it was showed that intrinsic growth rate (r„) and net reproductive rale (Ro) on big size host were lower compared with small size host while generation lime (T) on big host was longer than small host. Ro values were significantly different belween the two hosts. The result of this experiment also showed that on both host sizes, optimum value of T, Ro and rm was achieved on 26-28°C. These results arc expected to guide parasiloid breeders lo decide the temperature and host size in mass cultivating Trichogramma sp. in laboratory. While for ield application, tempeature and hosl range arc Ihe factors should be considered.

Carboxy methyl selulase and exo-polygalacturonase enzymes production and their role in determining the pathogenicity of Ralstonia solanacearum isolated from ginger

Bacterial wilt disease on ginger (Zingiber oicinale Roscoe) caused by Ralstonia solanacearum is the most destructive disease Infected tissues show macerated symptom on infected hosts indicating that the pathogen produces plant digestive enzymes. This research was aimed at analizing carboxymethylccllulasc (CMC-ase) and exopolygalacturonase (cxo-PG) enzymes production by the pathogen. In vitro production of CMC-ase of both virulent and avirulcnt isolates of R solanacearum was measured from diameter of clearing zone around bacterial colony on CMC medium whereas exo-PG was measured by the reduction of Na- polygalacturonatc by filtrate of the pathogen culture. Virulence of the pathogen was tested on tomato cultivar Gondol Hijau by pouring 50 ml of pathogen suspension (I07 cfu/ml) around roots of the plant and it was also tested on ginger cultivar Jahe Putih Besar by pricking suspension of pathogen into rhizome and basal pscudostcm of the plant. The results showed that CMC-ase and and PG-asc were produced by virulent isolates of R. solanacearum al 2.23 cm clear zone and 0.662 mg eq. glucose/ml/hour/ODiti, respectively. The avirulent isolates, however. correlated with disease intensity of the isolates. Disease intensity of the virulent isolates was 0.6 and 0.96 on tomato and on ginger plants respectively, whereas the avirulent isolates was 0.04 and 0.00 respectively. Therefore, CMC-ase and exo-PG are important in determining pathogenicity level of/?, solanacearum.

The change of colour was measured with Chrommameter CR-200. while the production of ethylcne, ACC (1-aminocyclopropanc-l-carboxylic acid) and MACC (malonyl-ACC) were measured with Photoaccuslic Spectroscopy, from the sample of 100 kg tobacco leaves cv. Jepon grown from April to September 1995 in Plakpak, Pcgantenan, Pamekasan, East Java. The experiment was designed as a completely randomized design in three replicates. The leaves samples were taken randomly from the mature middle leaves Results showed that endogenous ethylcne production al the irst day al a level of 169 ppb. was able to initiate ripening. Conversion percentage of ACC to ethylcne for 8 days ripening increased from 7.7 up lo 61.4 %. F tests least signiicantly different (1%). showed that yellow intensity signiicantly increased on the second day. This indicated thai ripening process was stated on the second day. On the other hand green intensity significantly decreased at the ifth day, thus no chlorophyl degradation. Brightness was signiicantly observed on Ihe third day of ripening, meaning that ripening stated on the third day. Based on the three criteria, the best ripening period was from the third lo the ilth day. This implies that the farmers will have three day periods of ripening which can be arranged to overcome the shotage of man power for slicing the leaves.

The cause of stunting disease of black pepper (Piper nigrum) in Indonesia has not yet been confirmed cither due o a virus or mycoplaam. However, similar disease found on black pepper plants in the Southeast Asia is caused by Piper yellow mottle virus (PYMV) which is transmitted by Planococcus citri. This expeiments was aimed o examine the cause of the stunting disease and its insect vectors. The expeiment were conducted from October 1998 to May 2001. Diseased vegetative materials of black pepper plants showing stunting disease were collected from Sukamulya, Sukabumi. The potential insect vectors were collected from black pepper plants in Bogor, IP Sukamulya (Sukabumi), Lampung and Bangka. The insects were fed on the diseased plants obtained from Lampung, Bogor and IP Sukamulya, then transferred o the healthy plants. The healthy plants were produced rom true seeds and cutings oiginated rom Bogor and IP Sukamulya. The tested plants were incubated at the green house and examined for disease development. Diseased leaf samples collected rom black pepper plant rom IP. Sukamulya and the transmitted plants were sent to the University of Minnesota, USA for Ihe virus (PYMV) by using ISEM (immunosorbent electron microscope). The result snowed that the leaves samples rom IP. Sukamulya were infected by PYMV. The morphology and size of the virus were similar to those caused stunting disease in the South East Asia. Potential insects vectors found on the diseased black

pepper plants were two mealybugs, P. minor and Ferrisia virgata (Hemiptera; Coccoidca: PaaidbcoccidaeX aa well as an aphid Toxoptera aurantii (Hemiptera: Aphidoidea: Aphididae). The first tial on disease transmission by using P. minor, previously reared on the potato tubers, showed one out of ten tested plants produced disease sympom. The subsequent trial using P minor, bred on healthy black pepper seedlings, showed thee out often tested plants developed disease symptoms. None of the aphid transmitted plants developed Ihe disease. This study confirmed thai PYMV b the cause of stunting disease on black pepper in IP Sukamulya and Lampung and P. minor as the insect vecor of the disease.

ABSTRACT

Effect of fertilizer application on the growth of young cashew plants in Bayan, Lombok

This study was conducted on young cashew trees grown in grayish- brown regosol soil located in Anyar Bayan (West Lombok) rom 1997 to 2000. The objective of this study was to find out the effect of NPK fertilizer and its composition on Uie growlh of me crops. The treatments were: (1) fetilizer rates (0, 150, 300, 450, 600 and 750 g NPK /tree/year); and (2) composition of NPK (2:1:1, 1:1:1 and 1:1:2). The treatments were arranged in randomized block design with 2 replicates, 4 plants per plot. Results showed that there was no significant interaction between fertilizer rate and its composition on the growth of the plants. Individually, however, both fertilizer rate and NPK composition significantly affected growlh of young cashew trees. Adequate rates of fertilizer application were 100, 200, 400 and 600 g NPK (in N, P2Oj dan KjO) per tree per year for 1, 2, 3 and 4 years old, respectively. Whereas, fetilizer compositions of NPK 1:1:2 and NPK 2:1:1 were suitable for young trees of 1-2 and 3-4 years old, respectively.

Published: July 2020

The purpose of the study was to analyze the role of rice’s price in household consumption patterns in Indonesia. The method used was the Quadratic Almost Ideal Demand System (QUAIDS). The data used were obtained from the National Social Economy Survey in 2016. The results show that when the price of rice increases by one percent, the demand for other carbohydrates, eggs-milk-beans, fruits also Cigarette and processed foods will be increase. Meanwhile, in other groups, when the price of rice rises, the demand will go down. Thus, it can be concluded that households still prioritize rice consumption in their daily consumption patterns compared to other commodity groups. Therefore, the government should develop policies that encourage people to consume more diverse food groups.
LA “AFECTACIÓN” DE LA CRISIS SANITARIA A LAS SITUACIONES CONCURSALES Y PARACONCURSALES EN VIRTUD DEL REAL DECRETO-LEY 16/2020, DE 28 DE ABRIL, DE MEDIDAS PROCESALES Y ORGANIZATIVAS PARA HACER FRENTE AL COVID-19 EN EL ÁMBITO DE LA ADMINISTRACIÓN DE JUSTICIA
Authors: Espigares Huete José Carlos
Published: July 2020

Nos parece un término particularmente idóneo el utilizado para estas reflexiones: porque “afectación” de la crisis sanitaria a las situaciones concursales es lo que se produce con el Real Decreto-ley 16/2020, de 28 de abril, de medidas procesales y organizativas para hacer frente al COVID-19 en el ámbito de la Administración de Justicia. Desde luego, al menos, en tanto que estas disposiciones producen una “alteración o mudanza” inmediata en algunos aspectos del régimen jurídico aplicable a las situaciones concursales y paraconcursales; y, también, en tanto que cualquiera de las demás acepciones de esta palabra podría ser perfectamente aplicable a lo que ha motivado estas medidas o a lo que está por venir una vez aplicadas. Nadie puede dudar de la oportunidad y necesidad de algunas medidas. Pero sí puede dudarse razonablemente de la suficiencia de las mismas y de la influencia favorable odesfavorable que tendrán sobre el devenir de las situaciones que regula. A nadie escapa tampoco que las dificultades de interpretación o de aplicación que puedan surgir determinarán en un grado notable los resultados a alcanzar.

Background

Pseudomonas aeruginosa ( P. aeruginosa ) is a major Gram-negative pathogen, which has been reported to result in high mortality. We aim to investigate the prognostic value and optimum cut-off point of time-to-positivity (TTP) of blood culture in children with P. aeruginosa bacteremia.

Methods

From August 2014 to November 2018, we enrolled the inpatients with P. aeruginosa bacteremia in a 1500-bed tertiary teaching hospital in Chongqing, China retrospectively. 52 case were analyzed. Receiver operating characteristic (ROC) analysis was used to determine the optimum cut-off point of TTP, and logistic regression were employed to explore the risk factors for in-hospital mortality and septic shock.

Results

Totally, 52 children with P. aeruginosa bacteremia were enrolled. The standard cut-off point of TTP was18 hours. Early TTP (≤18 hours) group patients had remarkably higher in-hospital mortality (42.9% vs 9.7%, P=0.014), higher incidence of septic shock (52.4% vs 12.9%, P=0.06), higher Pitt bacteremia scores [3.00 (1.00-5.00) vs 1.00 (1.00-4.00), P=0.046] and more intensive care unit admission (61.9% vs 22.6%, P=0.008) when compared with late TTP (>18 hours) groups. Multivariate analysis indicated TTP ≤18 h, Pitt bacteremia scores ≥4 were the independent risk factors for in-hospital mortality (OR 5.88, 95%CI 1.21-21.96, P=0.035; OR 4.95, 95%CI 1.26-27.50, P=0.024; respectively). The study also revealed that the independent risk factors for septic shock were as follows: TTP≤18h, Pitt bacteremia scores≥4 and hypoalbuminemia (OR 6.30, 95%CI 1.18-33.77, P=0.032; OR 8.15, 95%CI 1.15-42.43, P=0.014; OR 6.46, 95% CI 1.19-33.19 P=0.031; respectively).

Conclusions

Early TTP (≤18 hours) appeared to be associated with worse outcomes for P. aeruginosa bacteremia children.

Background: Chronic exposure to lead causes lead to accumulate mainly in the liver. In vivo studies have shown that lead toxicity is related to alterations in the inflammatory response. We aimed to evaluate the association between lead poisoning and liver fibrosis as well as the change in the degree of liver fibrosis, levels of inflammatory mediators and glutathione (GSH) after chelation therapy.Methods: Workers from a battery factory who were exposed to lead for > 12 months and had a blood lead level (BLL) > 70 µg/dL were enrolled (n=86) in the study. Participants underwent chelation therapy with intravenous CaNa2EDTA for 2 days followed by treatment with oral D-penicillamine for 90 days. The primary outcome was the change in the degree of liver fibrosis, which was presented as liver stiffness (LS) measured by FibroScan®. Secondary outcomes were the changes in the levels of serum GSH and inflammatory mediators such as tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) after chelation therapy.Results: Among the 86 participants, there was a positive correlation between the duration of lead exposure and LS (r=0.249, p=0.021). To avoid the confounding effect of obesity-related steatosis, only 70 individuals who had controlled attenuation parameters < 296 dB/m, BMI < 25 kg/m2 and normal waist circumference were included in the interventional analysis. After chelation, the mean LS significantly decreased from 5.4 ± 0.9 to 4.8 ± 1.4 kPa (p=0.001). Similarly, all of the inflammatory cytokines studied significantly decreased after chelation (p<0.001); TNF-α decreased from 371.6 ± 211.3 to 215.8 ± 142.7; the levels of IL-1β decreased from 29.8 ± 1.7 to 25.9 ± 4.3; and the levels of IL-6 decreased from 46.8 ± 10.2 to 35.0 ± 11.9. On the other hand, the mean GSH level increased significantly from 3.3 ± 3.3 to 13.1 ± 3.7 (p<0.001) after chelation therapy.Conclusion: The duration of lead exposure was significantly correlated with the degree of liver fibrosis. Chelation treatment was associated with increased levels of GSH and decreased levels of proinflammatory cytokines and could potentially reduce the degree of LS.Trial registration: This study was retrospectively registered and approved by the Thai Clinical Trial Registry (TCTR) on 2019-11-07. The TCTR identification number is TCTR20191108001. http://www.clinicaltrials.in.th/index.php?tp=regtrials&menu=trialsearch&smenu=fulltext&task=search&task2=view1&id=2867
