PERKEMBANGAN DAN POTENSI PRODUKSI PERIKANAN PELAGIS KECIL, SERTA STRATEGI PEMULIHAN SUMBER DAYA IKANNYA DI LAUT JAWA
Authors: Purwanto Purwanto 
Published: September 2022

Laut Jawa adalah salah satu daerah penangkapan utama perikanan pelagis kecil di Indonesia. Untuk pengelolaan perikanan tersebut, telah dilakukan pengkajian sumber daya ikannya. Hasil kajian menunjukkan bahwa produksi lestari maksimum (MSY) dari pemanfaatan sumber daya ikan pelagis kecil sekitar 312,1 ribu ton/tahun, yang dihasilkan dari penangkapan dengan upaya optimal (EMSY) setara dengan pengoperasian 996 kapal pukat cincin berukuran 80 GT dengan mesin utama 270 DK. Hasil kajian juga menunjukkan bahwa sumber daya ikan pelagis kecil di Laut Jawa sudah dimanfaatkan secara berlebih sejak 1999. Agar sumber daya ikan menghasilkan produksi pada tingkat MSY perlu dilakukan langkah pemulihannya, yaitu penghentian penangkapan ikan pada tahun pertama; kegiatan penangkapan dimulai kembali pada tahun kedua dari periode pemulihan dengan upaya penangkapan setara 80% dari EMSY dan tahun-tahun sesudahnya setara dengan EMSY. Bila terdapat resistensi kuat terhadap penghentian kegiatan penangkapan, strategi alternatifnya adalah pengendalian upaya penangkapan pada tingkat EMSY sejak tahun pertama periode pemulihan.The Java Sea is one of the main fishing areas for small pelagic fishery in Indonesia. To support the management of that fishery, an assessment of the small pelagic fish stock was conducted. The result shows that the maximum sustainable yield from utilizing small pelagic fish stock in the Java Sea was about 312.1 thousand tons per year, resulting from fishing activity with optimum effort (EMSY) equaling to the operation of 996 purse seiners of 80 GT with the main engine of 270 HP. Unfortunately, fishing effort was higher than EMSY and the fish stock has been over-exploited since 1999. To ensure the optimal sustainable production from utilizing the small pelagic fish stock, it is necessary to recover fish stock by halting fishing activity in the first year of the recovery period; the fishing activity should be started at the second year of the recovery period by controlling fishing effort at 80% of EMSY and at EMSY afterward. If there is strong resistance of fishers to the cessation of fishing activity, an alternative strategy should be controlling fishing effort at EMSY since the first year of the recovery period.

The Ross procedure was first proposed by Donald Ross in 1967. Numerous studies show excellent long-term outcomes of the Ross operation. One of its disadvantages is the intervention on two valves due to pulmonary homograft dysfunction.Aim. To study long-term outcomes of pulmonary homograft use after Ross operation (cumulative incidence of pulmonary homograft dysfunction, freedom from reoperation on pulmonary homograft, long-term survival, predictors of pulmonary homograft dysfunction) using data from one Russian center.Material and methods. A retrospective study included patients aged 18 years and older with aortic valve disease who underwent Ross procedure from April 2009 to December 2020 by a single surgeon. The age of the patients was 35 (26-44) years (men, 159 (75%)). Infective endocarditis as a cause of aortic valve pathology was diagnosed in 55 (26%) patients. Bicuspid aortic valve was diagnosed in 131 (62%) patients. The median follow-up period was 79 (26,5102,7) months.Results. Combined interventions were performed in 40 cases (18,9%). The modified Ross procedure was used in 54 (25,5%) cases (intra-aortic — 29, using Dacron tube graft — 25). Inhospital mortality was 0,5%. The 5- and 10-year allcause survival rates were 98,5% and 95,4%, while the 10-year cumulative pulmonary valve reoperation rate and pulmonary homograft dysfunction was 4,6% and 35,2%, respectively. The only factor affecting pulmonary homograft dysfunction was patient age ≤30 years (odds ratio =0,2 with 95% confidence interval: 0,06-0,7; p=0,02).Conclusion. Fresh pulmonary homografts have a low incidence of dysfunction and reintervention after Ross procedure. Young age is the only independent risk factor for pulmonary homograft dysfunction.

Published: September 2022

Introduction. Allergic reactions and side effects are a common consequence of drug use and account for ~5% of all hospital admissions. The co-occurrence of ana phylactic shock and acute myocardial infarction (AMI) is called Kounis synd rome (KS).Brief description. The article analyzes the case of ceftriaxone-induced KS in a 56-year-old female patient with a history of anaphylactic shock after ampicillin therapy. The patient was treated on an outpatient basis due to an acute upper respiratory infection. The patient was diagnosed with acute bronchitis, in connection with which antibiotic therapy with azithromycin was started. Due to inefficiency the drug was canceled and ceftriaxone 1 g in 3,5 ml of 1% lidocaine solution 2 times a day was prescribed. After the first intramuscular injection, the patient developed anaphylactic shock, which was stopped by intravenous administration of prednisolone 120 mg, dexamethasone 8 mg and adrenaline hydrochloride 1,0 ml. Almost immediately, the ST segment elevation was recorded, in connection with which thrombolytic therapy with fortelyzin 15 mg was performed. Coronary angiography revealed thrombotic occlusion of the left anterior descending artery in the upper segment. Further examination verified AMI in the patient.Discussion. This case of AMI is pathogenetically associated with anaphylactic shock. However, the available data on the state of patient coronary system and no data on the morphologic characteristics of thrombus do not make it possibelr to define a type of KS.Conclusion. This clinical case indicates the need for a thorough allergic anamnesis collection by physicians of any specialty and prescribing medications taking it into account.

Breast cancer has been attributed to be the second most common malignancy in females worldwide after skin cancer associated with a significantly high mortality rate. Tumor suppressor genes have an indispensable role in maintaining genomic integrity as well as cell cycle regulation. Phosphatase and tensin homolog deleted on chromosome ten (PTEN) is one of the most frequently mutated human tumor suppressor genes, implicated in cell growth, survival, and suppressing tumor formation. As the tumor progresses to more advanced stages, genetic alterations tend to increase one such alteration is the mutation of the PTEN gene which is linked to programmed cell death and maintenance of cell cycle regulation. There is a syndrome known as Cowden syndrome associated with a high risk of breast cancer which is a result of an outcome of germline mutations in the PTEN gene. Loss of PTEN activity, either at the protein or genomic level, has been related to many primary and metastatic malignancies including breast cancer. This study focuses on developing a potential bioavailable ligand inhibitory molecule for PTEN, using a computer-aided drug design approach (CADD). A library of developed ligands consisting of 50 potential molecules was screened to find a potential candidate to be used for second generation drug development. Among them, LIG28 was adjudged as the most effective and potential PTEN inhibitor given its maximum binding affinity of ΔG -5.96Kcal/mole with a lower RMSD value. Carmer’s Rule of toxicity further revealed the compatibility and non-toxicity of the molecule. These observations underscore the importance of PTEN as a target in the development of tumorigenesis and the prognosis of breast cancer.

Published: September 2022

Knowledge of the feeding habit and the digestive physiology of a fish is important in making appropriate strategies for feed development and successful culture. Nutrient-rich small indigenous fish species (SIFs) are abundant in Assam, India. Puntius sophore, Mystus tengara, and Trichogaster fasciata of Gossaigaon, Assam are important SIFs for the local rural population, and also potential candidates for ornamental fish culture. The present study aims to evaluate the feeding habit and digestive enzyme activities of these species. Data obtained from the relative gut length and gut content analysis suggested that M. tengara is a carnivorous fish and the rest two fishes are omnivorous in habit. Further, the relative gut length was highest in T. fasciata (4.20±0.45) and lowest in M. tengara (0.55±0.11). Digestive enzyme activity indicates a correlation with the dietary habit of the fish. Further, total protease, trypsin, and amylase activity was reported highest in P. sophore. Acid protease pepsin was found to be significantly higher in M. tengara complementing its carnivorous habit and gut anatomy. The present study has established some important information on the digestive enzyme characteristics and feeding habits of the three fish species. This information might be useful in the development of suitable feed for the fish species for their culture.

Technika spektrometrii w podczerwieni (IR) stosowana jest do identyfikacji substancji organicznych, polimerowych i w niektórych przypadkach materiałów nieorganicznych. Zgodnie z tezą, że era paliw kopalnych powoli zbliża się do końca, zaistniała konieczność szukania i testowania alternatywnych źródeł energii. Gaz ziemny zawierający metan stanowi źródło energii wytwarzające duże ilości gazów cieplarnianych. Magazynowanie i wytwarzanie energii z paliw takich jak biogaz stanowi jedno z wielu innowacyjnych podejść podczas produkcji w zamkniętych, neutralnych pod względem CO2 obiegach (biogazownie). Technologie służące do wytwarzania biogazu i wykorzystujące biogaz kwalifikują się do otrzymania dofinansowania wspierającego rozwój OZE. Biogaz jest uważany za odnawialne źródło energii, obieg węgla w cyklu produkcji jego surowców i zużycia jest zamknięty i nie wiąże się z emisją netto dwutlenku węgla. Spektrometry IR pracujące zarówno w zakresie średniej, jak i bliskiej podczerwieni dają możliwości analizy chemicznej i materiałowej z dużą czułością i dokładnością, przez co mogą być szeroko stosowane w monitorowaniu środowiska lub do kontrolowania prowadzonych procesów technologicznych. W artykule opisano analizę próbek biogazu za pomocą spektrometrii w podczerwieni z transformacją Fouriera z zastosowaniem kuwety gazowej o regulowanej drodze optycznej. Badane próbki pochodzą z przerobu odpadów gorzelnianych. Przedstawiono analizę próbek gazów wzorcowych będących głównymi składnikami biogazu oraz dokonano porównania otrzymanych widm IR z widmami rzeczywistych próbek biogazu. Podjęto próbę określenia możliwości użycia tej techniki do wykrywania zanieczyszczeń, takich jak obecność gazowego amoniaku. Przeprowadzone badania potwierdziły możliwości analityczne badania głównych składników biogazu. Zawartość substancji będących zanieczyszczeniami biogazu może okazać się za niska do ich oznaczenia w przypadku ich śladowych ilości, wtedy spektrometria IR może okazać się niewystarczająca m.in. do oceny skuteczności prowadzonych procesów oczyszczania biogazu, dlatego należy ją stosować w połączeniu z analizą GC.

Este artigo pretende reunir diferentes práticas de pesquisa com arquivos, entre públicos e privados, no intuito de evidenciar a importância de uma disposição de escuta e observação, e não somente de questionamento e interrogativa, diante dos conjuntos documentais e suas formas de organização. As perguntas aos arquivos nos guiam nas pesquisas pelas quais chegamos a eles. Mas o arquivo tem também suas demandas, aquelas projetadas por seus gestores e aquelas solicitadas pela (sobre)vida das imagens (DIDI-HUBERMAN 2013) e documentos. Como corpo pulsante, o arquivo, existente ou inventado na pesquisa, que pode condicionar leituras pelos seus regimes de visibilidade, também sugere sutis movimentos, entre mostrar, ouvir, inventar, criar, constelar. Que perguntas emergiram diante de alguns arquivos, além das interrogativas que nos levaram até eles? Quais demandas os sujeitos gestores mas também os corpos documentais apresentaram? Que cidades podemos vislumbrar nessas urgências de arquivo? Para tentar responder a essas perguntas vamos apresentar 5 situações de pesquisa em arquivo que evidenciam 5 diferentes ações de investigação (investigAção) com conjuntos documentais. Esses 5 arquivos - Arquivo UFBA/MAP (Meta Arquivo UFBA70), Acervo Aracy Esteve Gomes, Laboratório de Fotodocumentação, Acervo Arlete Soares e Zumvi Arquivo Afro Fotográfico - colocaram diferentes solicitações em função das urgências emanadas daqueles acervos e de seus gestores, evidenciando que, ao tempo que precisamos fazer o arquivo falar, é também importante atentar-se a perscrutá-lo com uma escuta sensível.

Published: September 2022

There is widespread agreement that 21st-century skills are skills that should be possessed by students in the current era; however, generally, the component value of these skills is low. This research aims to investigate the effectiveness of the physics electronic teaching material-integrated STEM education (PETMS) in improving the 21st-century skills of students. This research was an experimental study with a post-test-only design with a non-equivalent group. The research subjects consisted of 66 students in two groups. The results indicated that the use of the PETMS was effective in improving students’ mastery of concepts and three aspects of 21st-century skills: creative thinking, critical thinking, and communication. Based on this result, it is inferred that the PETMS is an effective teaching material in promoting students’ 21st-century skills and is expected to be a relevant reference to enhance the quality of physics learning and to apply in the 21st-century learning era.

Published: September 2022

Character is an important aspect that needs to be instilled in students from an early age. However, the coronavirus pandemic has changed the learning process from offline to online so that character formation must be identified whether it is in accordance with before. This study aimed to identify the character-building process of students learning mathematics in elementary schools during the coronavirus pandemic. This study used a qualitative approach with phenomenological methods. Data were collected through observation (descriptive, focused, and selected), and interviews. The data were analyzed using domain analysis techniques, taxonomic analysis, componential analysis, and theme analysis. The research subjects consisted of students and mathematics teachers at Elementary schools. The results showed that students formed through online mathematics learning during the coronavirus pandemic were honest, disciplined, and responsible. Forming students' character in learning mathematics is carried out by exemplary methods, habituation, and inculcation of values.

Published: September 2022

This study assessed the perceived teachers’ competence and benefits of inclusion to learners. There were 63 teachers who answered the survey questionnaires that assessed their perceived competence and benefits of inclusive education. They were identified using cluster sampling. The data gathered were treated using descriptive and inferential statistics. The results revealed that majority of them were in the age range of 33-42 years, had finished their master’s degree with specialisation not related to special education and had served in their school for 8-16 years. They perceived themselves to be highly competent and stated that inclusive education is highly beneficial for learners with and without special education needs. Moreover, their perceived competence is significantly related to the benefits of inclusive education for learners with and without special needs. Hence, school administrators need to validate the teachers’ perceived competence in handling inclusive classes and create programmes geared towards an enhanced inclusive education implementation.

Published: September 2022

In society 5.0, everyone is faced with multiliteracy. Ideally, this multiliteracy is learned from elementary school. However, information on the implementation of learning that trains multiliteracy has not been widely studied. This study aims to describe or photograph the implementation of multiliteracy learning carried out by teachers in elementary schools. This research is a phenomenological type of qualitative research. The participants of this study were elementary schoolteachers in Indonesia. Data were collected by interviewing teachers and observing multiliteracy learning in schools. Data analysis was carried out using the Bogdan and Biklen model with the stages of data reduction, data presentation, conclusion drawing and verification. The results show that the teachers’ understanding of multiliteracy was not correct. The implementation of learning that leads to multiliteracy learning has not been carried out; it is still limited to reading and writing activities.

Keywords: Multiliterate learning, elementary school, phenomenology.
