Abstract

Slow-release fertilizer can provide nutrients more efficiently; nutrients are released and available slowly so that they have the potential to be absorbed by plants. This study aimed to investigate the effects of several slow-release N fertilizers on the growth and yield of corn (Zea mays L.) in sandy soil. This research was carried out in the greenhouse and laboratory of the Faculty of Agriculture, University of Trunojoyo Madura. The experiment was arranged on a non-factorial completely randomized design. There were six treatment levels, namely P0 (uncoated urea fertilizer, applied into one application), P1 (uncoated urea fertilizer, split into three times applications), P2 (urea fertilizer with bentonite coating, P3 (urea fertilizer with biochar coating), P4 (urea fertilizer with coal coating), and P5 (urea fertilizer with biochar compost coating). All coated urea fertilizers were applied one time at the early growth of corn. The results showed that the application of slow-release N fertilizer had no significant effect on plant height, number of leaves, leaf area, cob length, diameter, plant fresh weight, plant dry weight, seed weight per plant, 100 seed weight, and flower age. However, the application of slow-release N fertilizer had a very significant effect on plant height at 42 DAP, the number of leaves at 14 DAP and 56 DAP, and leaf area at 28 DAP and 56 DAP. All coated urea fertilizers were as effective as uncoated urea on the growth and yield of corn.

Abstract

Maize is one of the most important food commodities after rice and is widely cultivated because it has a high protein value. The purpose of this study was to determine the effectiveness of the coating material on the growth and yield of maize under saline stress. This research was conducted in the Agroecotechnology greenhouse of the Faculty of Agriculture, University of Trunojoyo Madura from August 2022 to January 2023. This study used a factorial Completely Randomized Design (CRD) with 10 treatment combinations and 3 replications with a factor of one coating material (P) and a factor of two salinity (K). The coating material factor consisted of 5 treatments namely control (P0), bentonite (P1), biochar (P2), light coal (P3), and biochar compost (P4), the saline stress factor consisted of 2 treatments namely control (K0) and saline (K1). The results showed that the application of coating material to saline stress had a significant effect on all growth parameters. The interaction between treatments only had a significant effect on plant height at 1 MST, leaf area at 6 MST, and 100 seed weight. Treatment (P2K1) with biochar and saline showed the best results on all growth and yield parameters of maize. Saline stress reduced the percentage of growth and yield of maize by about 50%.

Abstract

Refugees are defined as people who are due to a reasonable fear of persecution, caused by reasons of race, religion, nationality, membership in certain social groups and political parties, are outside their nationality and do not want protection from the country. When refugees leave their home country or residence, they leave their lives, homes, possessions and family. The refugees cannot be protected by their home country because they are forced to leave their country. Therefore, protection and assistance to them is the responsibility of the international community. In countries receiving refugees, they often experience inhumane treatment such as rape, assault, discrimination, repatriated by force, those lead to the violation of human rights. There has been regulation for human rights in refugee issues both internationally and regionally, for instance Convention related to Status of Refugee 1951 and The Protocol related to the Status of Refugee 1967. There are at least five basic rights of refugees, they are the right to be protected from returning to the country of origin forcibly (non refoulement), the right to seek asylum, the right to obtain equality and non-discrimination, the right to live and to be secured, as well as the right to return home.

Abstract

This study aims to describe (1) the types of speech acts and implicatures in caricature discourse; (2) the linguistic aspects inherent in caricature discourse and; (3) caricature readers' understanding of the social functions in caricature discourse. The research methodology used is descriptive qualitative research. Data collection techniques used interviews, observation and document analysis. The sampling technique used was purposive sampling technique. Data validity was validated by using data source triangulation. Then the analysis model uses an interactive model from Miles and Huberman. The results showed that many caricatures were drawn mainly to put forward constructive ideas about existing issues and to emphasize the humorous function. The types of speech acts utilized in caricature drawings are directive, commissive, expressive, and permissive speech acts. The linguistic aspects utilized in caricature discourse are, phonological aspects in the form of anomatope or sound imitation, words, phrases, sentences, and discourse. In the end, readers and caricature makers often have different understandings of the social function of caricature discourse texts. They have different understandings and interpretations of the meaning contained in the text and images of caricatures in relation to constructive criticism.

Abstract

This study was conducted to evaluate the effect of chemical fertilizer coated with biochar on the growth of shallots (Allium ascalonicum L.) in sandy soil. The research was carried out at the Greenhouse of the Agroecotechnology Department, Faculty of Agriculture, Trunojoyo University of Madura, located in Telang Village, Kamal District, Bangkalan Regency, Madura, at an altitude of approximately 5 meters above sea level, from August to December 2023. A non-factorial Completely Randomized Design (CRD) was used, consisting of six treatments: P0 (control), P1 (recommended fertilizer), P2 (80% urea coated with rice husk biochar + bentonite), P3 (100% urea coated with rice husk biochar + bentonite), P4 (80% urea coated with corn cob biochar + bentonite), and P5 (100% urea coated with corn cob biochar + bentonite). The results showed that the application of biochar-coated urea fertilizer had no significant effect on plant growth and yield parameters such as plant height, number of leaves, number of tillers, number of tubers, tuber diameter, and root volume. However, plant height at 42 days after transplanting (DAT), the number of tillers at 42–63 DAT, and chlorophyll content showed significant differences among the treatments. Additionally, soil analysis parameters—including pH, organic carbon (C-organic), and soil nitrogen (N)—showed significant responses to the treatments.

Abstract

Kegiatan belajar mengajar di Lembaga Pendidikan Al Qurán An Nur terdiri atas Pembelajaran membaca Al Qurán (dengan metode IQRO’) dan Menulis Huruf dan Angka Arab (Al Qur’an) serta bagi santri yang telah khatam Al Qurán 30 Juz mereka mendapat bimbingan tambahan menghafal Al Qur’an, terjemah lafziyah, menghafal Hadis, Mahfuzhat mengenalkan bahasa Arab, Terjemah Al Qur’an dengan Bahasa Indonesia dan Bahasa Inggris dengan jadwal belajar dari pukul 14.30 sampai dengan 18.00. Kegiatan pembelajaran di LPQ An Nur berupa kegiatan baca dan tulis, dimana kegiatan ini harus ditunjang oleh fasilitas pencahayaan yang baik. Sesuai dengan Standar Nasional Indonesia, intensitas cahaya yang dibutuhkan untuk kegiatan ruang kelas adalah sebesar 250 lux. Hasil survei lapangan terukur intensitas cahaya di ruangan kelas sebesar 86.1 lux tanpa pencahayaan lampu dan terukur dengan nilai 132.4 lux , kedua nilai tersebut masih dibawah nilai SNI. Untuk mengatasi masalah tersebut, dilakukan pembenahan berupa penggantian lampu dengan nilai lumen sesuai dengan perhitungan yang mempertimbangkan luasan ruang kelas dan nilai lux yang diharapkan. Dari perhitungan, dilakukan pembenahan lampu dengan 3300 lumen dan daya 30 Watt untuk menggantikan lampu sebelumnya. Dengan penggantian lampu tersebut, menaikan intensitas cahaya di ruangan kelas sebesar 298 lux sedikit mendekati nilai lux ruang baca sesuai nilai SNI. Peningkatan nilai lux memberikan konsekuensi peningkatan nilai daya per lampu yang awalnya 8 Watt menjadi 30 Watt, sehingga memberi dampak kenaikan konsumsi energi listrik bulanan untuk pencahayaan dan bertambahnya biaya operasional bulanan LPQ An Nur

Abstract

Various activities especially in fulfillment daily needs, generate a lot of waste. One of the negative effects of waste generation is the contribution of greenhouse gas emissions to the atmosphere which causes global warming. Every location has waste, both organic and non-organic, or other types. The open space in Bendan Dhuwur campus area is dominated by organic waste due to leaf fall from many trees around. This is a concern because there is no proper waste management and it is immediately burned. This study focuses on analyzing the composition of waste and calculating the contribution of CO2 emissions from domestic waste generation at Bendan dhuwur campus of UPGRIS Semarang. The method used is random sampling accompanied by quantitative descriptive measurements and analysis. The result of the research shows that the calculation of waste composition for leaf waste is 3.58 x 10-3 Gg/year; twig waste 3.6 x 10-4 Gg/year; paper waste 3.57 x 10-4 Gg/year; plastic waste 2.02 x 10-4 Gg/year and CO2 emissions = 2.12 x 10-3 Gg/year; CH4= 2.57 x 10-5 Gg/year (leaves), CO2 = 2.18 x 10-4 Gg/year; CH4=2.58 x 10-6 Gg/year (twig), CO2 = 1.53 x 10-4 Gg/year; CH4= 2.56 x 10-6 Gg/year (paper), CO2 = 0.02 Gg/year; CH4= 1.45 x 10-6 Gg/year (plastic) Keywords: waste, CO2, CH4

Abstract

This study is an autobiography of the author's experience as an English teacher teaching 12th graders digital multimodal composing (DMC). I have been teaching vocational high school students for seventeen years in one of Indonesia's vocational high schools. I am still looking for the best way to develop the writing skills of vocational high school students. I want to alter their perceptions of writing. It is essential to create a fun and meaningful writing process both inside and outside the classroom. Students born in the twenty-first century, the digital generation, and modern students. DMC as the textual practice entails using digital tools to generate text by combining various semiotic modes. Each mode is meaningful and serves a purpose. As a teacher, I can create any digital mode based on my students' needs and knowledge. This study used the narrative inquiry method to explore and reflect on the story of the teacher.

Abstract

Indonesia needs to adopt the agricultural technique that gives high production to fulfill the need of its population. Automatic fertilizing with a drip irrigation system is one of the agricultural technologies to boost yield. Using this fertigation technology involves giving specific nutrients to plants based on their demands to conserve resource inputs. The potential for developing lettuce as an export commodity is highly encouraging. This study was to build an automatic fertigation device that includes a drip irrigation system, environmental management and to decide whether to test the device on green lettuce (Lactuca sativa L.). The research results are anticipated to be adopted and expanded in the community. The research began with designing and preparing instruments and materials; testing each instrument element; construction and programming; system testing tools; and evaluating lettuce plants. This instrument employs sensor components, microcontrollers, and actuators and is based on the IoT (Internet of Things). The results showed that the apparatus could function effectively following the program's specifications. However, the sensor could perform the tool's performance with high accuracy and be tracked by an Android smartphone. Testing the apparatus on lettuce plants showed that the plant tended to improve its height and yield in terms of fresh weight and economic weight compared to the plant watered manually. Moreover, there was less variation in the number of leaves of the plant.
