DIAGNOSIS KESEIMBANGAN HARA N, P, K DAN Mg PADA JERUK SIEM MENGGUNAKAN METODE DRIS DI KECAMATAN CLURING

Perunurnan Produktivitas jeruk dapat dipengaruhi oleh ketidak seimbangan hara pada tanaman. Penelitian ini bertujuan untuk mengetahui faktor pembatas kadar hara N. P. K dan Mg serta perbaikan keseimbangan hara tanaman melalui rekomendasi pemupukan di Kecamatan Cluring. Metode pengkajian menggunakan DRIS (Diagnosis and Recomendation Integraed System) untuk menganalisis interaksi kadar hara dalam tanah dan jaringan tanaman jeruk. Analisis daun dalam menetapkan N menggunakan metode Kjeldahl dengan cara pengabuan basah H2SO4, sedangkan P, K dan Mg dengan pengabuan basah HNO3 dan HClO4. Hasil penelitian menunjukkan bahwa nilai norm n/p, n/k, k/p, n/mg, p/mg dan k/mg berturut turut adalah 7.63, 1.50, 5.36, 14.81, 1.88 dan 9.90. Nilai rata-rata indeks hara N. P. K dan Mg di kebun jeruk berproduktivitas optimum berturut-turut adalah (-0.39), (-0,07), (-1.56) dan 7.38. Hara pembatas pada sebagian besar kebun jeruk berproduktivitas rendah - sedang adalah hara nitrogen dan fosfor. Urutan hara yang harus diperbaiki pada kebun jeruk berproduktivitas rendah (<22.5 ton/ha) hingga sedang (22.5 – 27.5 ton/ha) berturut-turut adalah nitrogen, fosfor dan kalium. Rekomendasi pupuk untuk musim selanjutnya pada kebun jeruk berproduktivitas rendah adalah Urea 239.13 Kg/ha, SP36 338.89 Kg/ha dan ZK 80 Kg/ha, sedangkan pada kebun jeruk berproduktivitas sedang adalah Urea 204.35 Kg/ha, SP36 300 kg/ha dan ZK 170 kg/ha.Kata kunci: Tanaman jeruk, diagram DRIS dan Faktor pembata

STRUKTUR MIKRO BAHAN PROPELLER DARI KOMPOSIT ALUMINIUM 6061-ALUMINIUM OXIDE DENGAN METODE SQUEEZE CASTING

The composite is a combination of two or more materials that form a bond, in which eachmaterial has different elements and forms a new material. One way to improve themechanical properties of composite materials is by heat treatment T6 consisting of threestages: 1. Solution treatment, 2. Quenching, 3. Artificial aging. The purpose of this study isas a comparison between the influence of type variations and temperature of cooling mediato the change of shape, dimensions, distribution of hardness and microstructure after andbefore T6 process of composite material aluminum 6061-aluminum oxide by squeeze castingmethod. In the process of T6 is done solution heat treatment at temperature 530℃ for 2 hoursand aging at temperature 180 ℃ for 2 hours. Specimen 9 with variations of coolant mediatype (water, brine, and oil SAE 40) and variations of coolant media temperature (roomtemperature, 70℃, dan 110℃). From the result of measurement and testing conducted showthat, changes in shape and dimensions are irregular due to non-uniform cooling rates. Thevalue of hardness increases after the heat treatment process and the value of hardness thatexist in the variation of the type and temperature of irregular cooling media, because it isinfluenced by the internal condition of the material. XRD microstructure testing showed thatall specimens in the compound candidate (Al, MgO, Si, and O) had a percentage value andthe compound formed differently. But the MgO compound affects changes in shape anddimension, If the value of MgO percentage is low then the change of shape and dimensionhas the biggest difference value. While the MgO is high then the change of shape anddimension has the smallest difference valu

Gambaran Intervensi Perawat dalam Asuhan Keperawatan Pasien Tuberkulosis Paru di Rumah Sakit

Introduction: The nurses’ role within nursing care of tuberculosis patients in hospitals is  very important. Nurses problem are preparing nursing interventions in patients with pulmonary tuberculosis rarely use the standard Nursing Intervention Classification (NIC). Independent nursing interventions are not in accordance with the diagnoses established by nurses, so the impact on the implementation needed by patients is not in accordance with the problems occured. Collaborative intervention is mostly carried out by nurses compared to independent intervention. Nurses must arrange nursing interventions based on the standard of nursing diagnoses that are enforced. The objective study was to describe the interventions compiled by nurses at the hospital.Methods: Research design was qualitative research with observational approach. Sample was 100 nurse’s documentastions  of  pulmonary tuberculosis patient  in TB MDR ward. Data analysis used language and text analysis with content analysis. Results: The results research was the highest 10 interventions written by nurses is intervention about observe general condition of patient was 83 times, collaboration with  doctor’s therapy was 54 times, give comfort position was 54 times, give therapy was 47 times, check vital signs regulerly was 40 times, give oxigen was 34 times, advise to bedrest was 30 times, teach  to effective cough was 25 times, Give position semi fowler was 15% times, and teach to deep breath was 15 times. Conclusion: Nurses must improve their skills and knowledge in preparing treatment plans, because the interventions that have been prepared have not been optimal for dealing with patient problems in hospitals. Interventions to improve patient knowledge and abilities in the management of the disease are important to give to patients.

Seismic Vulnerability Evaluation of Existing Structures Using the Rapid Visual Screening Method in Malang City

Indonesia is characterized by its volcanic mountain ranges and bordered by several tectonic plates. This geographical setup makes Indonesia susceptible to both tectonic and volcanic earthquakes. The Indonesian National Standardization Body issued the latest earthquake regulations in 2019, leading to changes in the seismic hazard values used as reference in seismic design. As a result of these regulation changes, seismic load designs have been updated. While these regulations are applicable to the planning of new buildings, it’s equally important to assess existing structures to determine if they can withstand the updated seismic loads. This research focuses on evaluating the vulnerability of older buildings constructed before the implementation of the new earthquake regulations. The assessment method employed is Rapid Visual Screening (RVS). This study was conducted in Malang City, as it falls within an area of moderate to high seismicity. After conducting the RVS method, a numerical analysis was performed on a sample of buildings for comparison. The research findings indicate that the examined buildings are still capable of withstanding the updated seismic loads

Hubungan Peran Tim Pencegahan dan Pengendalian Infeksi (Tim PPI) dan Fasilitas Cuci Tangan dengan Kepatuhan Cuci Tangan Perawat

Introduction: Health care associated infections (HCAIs) are infections that patients get during hospitalization. The most effective prevention of HCAIs is hand washing. Hand washing compliance behavior is still quite low. Nurses' hand washing compliance needs to be improved by optimizing the role of the Infection Prevention and Control Team (PPI team) and adequate hand washing facilities. Research related to the role of the PPI team and existing hand washing facilities still shows mixed results, therefore it is interesting to study.Methods: This study used a descriptive correlational design that aims to determine the relationship between the role of the PPI team and hand washing facilities with nurses' hand washing compliance. The research sample consisted of 204 nurses who were taken at simple random, data collection using questionnaires and observation sheets. The questionnaire consisted of 10 questions for the role of the PPI Team variable and 5 questions for the variable hand washing facilities and 11 statements for observing nurse handwashing compliance.Results: The results showed that nurses who obeyed hand washing were 88% and did not comply with 12%, the role of the PPI team performed well at 97.5% and not good 2.5% and the availability of hand washing facilities were considered good at 97.5% and not good 2,5%. The results of the Chi-Square test showed that there was a significant relationship between the role of the PPI team and nurses' hand washing compliance (P = 0.0001) and there was a significant relationship between the completeness of hand washing facilities and nurses' hand washing compliance (P = 0.007).Conclusion: Based on the results of this study, nurses are expected to be able to maintain and improve hand washing and transform these good habits for other health teams, patients, families, and visitors. In addition, the PPI team must continue to work optimally and the hospital can provide complete hand washing facilitie
