Abstract

Bamboo is an abundant biomaterial having important potential as a resource for bioenergy development. In this study, the potential of andong (Gigantochloa pseudoarundinacea (Steudel) Widjaja) bamboo for pellet production was evaluated. Some properties of bamboo pellets as density, moisture content, moisture adsorption, compressive strength, and heating value were analysed. The results indicated that bamboo is highly prospective to be explored for fuel pellets commercially. All characteristics of pellet made of bamboo fulfilled the requisites of the commercial pellets. The heating value of the pellets achieved the minimum standard for commercial pellets along with SNI 8675:2018 (>17,5 MJ/kg). The effects of culm parts on the moisture content, density, moisture adsorption were not significant. There were significant differences in compressive strength and heating value between bamboo pellets produced from different culm parts. This research showed potential of andong bamboo pellet for bioenergy resource. Keywords:   Andong (Gigantochloa pseudoarundinacea), Biopellet, Mechanical Properties, Physical Properties

Abstract

 Penggunaan sumber energi dari fosil secara terus menerus mengakibatkan pasokan minyak bumi menjadi terbatas, sehingga dibutuhkan inovasi energi terbarukan. Tandan kosong kelapa sawit (TKKS) merupakan salah satu limbah padat dari industri minyak sawit yang potensial untuk digunakan sebagai energi terbarukan karena ketersediaannya yang melimpah dan harga bahan baku yang relatif murah. Sifat-sifat TKKS dapat ditingkatkan menggunakan metode torefaksi. Torefaksi adalah perlakuan termokimia pada kisaran  suhu 200-300°C dengan kondisi inert (oksigen terbatas).  Penelitian ini bertujuan untuk mengetahui perubahan sifat fisis pelet TKKS melalui torefaksi dengan menggunakan electric furnace (EF). Torefaksi pelet TKKS pada penelitian ini menggunakan suhu 280°C dengan durasi 20 menit.  Pengujian pelet TKKS meliputi perubahan warna, kerapatan, kadar air, dan ketahanan terhadap perendaman air. Hasil penelitian menunjukkan bahwa warna pelet tandan kosong kelapa sawit berubah total setelah torefaksi dengan nilai perubahan warna (ΔE*) sebesar 14,97. Kerapatan awal pelet sebesar 0,58% g/cm3 menurun dan setelah torefaksi menjadi 0,48 g/cm3. Kadar air awal pelet tandan kosong kelapa sawit sebesar 11,54% menurun setelah torefaksi menjadi 6,66%. Uji ketahanan terhadap air menunjukkan bahwa pelet yang ditorefaksi lebih tahan terhadap air dibandingkan pelet yang belum ditorefaksi, sehingga akan sangat menguntungkan ketika pelet disimpan dalam waktu yang lama dan pada kondisi lembab. Kata kunci: sifat fisis, tandan kosong kelapa sawit, torefaksi, warna.

Abstract

Chronic kidney disease is a condition where the kidneys fail to perform their function to excrete substances that are not needed by the body, resulting in accumulation in the body which can trigger uremia. This scientific work aims to apply nursing care to CKD patients with ineffective breathing patterns at Ibnu Sina Gresik Hospital. The method applied in the preparation of this scientific work is the case study method. The subjects in this scientific work are participants with CKD cases and have problems with ineffective breathing patterns who are undergoing treatment at Ibnu Sina Gresik Hospital. Data collection using interview techniques, observation, physical examination, and documentation and was carried out in the period January to March 2023. The nursing care process for participants was carried out for 5 days, and the assessment results were obtained, namely shortness of breath. The implementation process is carried out in accordance with nursing care planning, one of which is by giving the semi-fowler position. A thorough evaluation was carried out during the provision of nursing care, and it was found that the participants with the problem of ineffective breathing patterns were resolved. Participants do not complain of shortness of breath, breathing frequency improves or is in the normal range, dyspnoea decreases, and there is no use of breathing muscles. The problem of ineffective breathing patterns is resolved by the application of nursing care that is carried out comprehensively. Giving the semi fowler position has an impact on reducing ineffective breathing patterns, because in a tilt angle of 45 degrees and applied during treatment is able to press the diaphragm down so that the lungs can expand and get maximum oxygen supply. Keywords: Chronic Kidney Disease, Ineffective Breathing Pattern, Semi-Fowler's Position.

Abstract

This study aims to determine the effect of substrate composition on biogas production from a mixture of cow dung and elephant grass using semi-continuous digester. Fresh cow dung and elephant grass were obtained from Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. Elephant grass was knife-chopped, crushed using a blender and then mixed with cow dung at a total solid (TS) ratio between elephant grass and cow dung varies from 35:65 (P1), 40:60 (P2), 45:55 (P3), and 50:50 (P4). This mixture was then diluted with tap water until its TS content reach 5% and was used as substrate. Four semi-continuous digesters (labeled as P1 to P4) having a capacity of 36 L and working volume of 28 L were initially loaded with 22 L of diluted fresh cow dung (dilution ratio of 1:1) as a starter (source of bacteria) and were left until stable condition. When the biogas was produced, the prepared substrate was added daily into the respective digester at a loading rate of 500 mL.d-1. Parameters to be observed included daily temperature and pH of the substrate, daily biogas production, TS and VS content, and biogas quality. The results showed that the digester worked at average pH of 6.9 and the daily temperature 26.3 to 29.7°C. The total biogas production for 60 days was 608.4, 676.8, 600.0, and 613.3 L, respectively for P1, P2, P3, and P4. Biogas yield after the substrate achieving the designed composition was 254 (P1), 260 (P2), 261 (P3), and 271 L.m-3 of the substrate (P4). The addition of elephant grass up to 50% could maintain high production of biogas.
