Abstract

TSS (True Shallot Seed) need to be developed to address the quality and quality of shallot seeds. The seeds, however, still has constraints on its viability and germination. The objective of this study was to investigate the effect of corona discharge plasma radiation on the viability of true shallot seeds. The research was conducted in March - April 2023 at the Plasma Laboratory, Faculty of Science and Mathematics, Diponegoro University, and the germination test experiments at the the Agricultural Technology Research and Assessment Installation (IP2TP Ungaran). The experiment was designed completely randomized with 6 treatments of radiation time consisting of P0 (without radiation), P1 (5 min), P2 (10 min), P3 (15 min), P4 (20 min), and P5 (25 min). All treatments were carried out with 5 replications. The collected data were processed using ANOVA and then continued with the DMRT test. The results showed that the corona plasma radiation treatment for 15-25 min affected the parameters of germination, germination rate, seed growth rate, vigor index, seed uniformity, and sprout length.  Keywords: Plasm, Radiation, Shallots, TSS.

Abstract

Shallots are bulb-shaped commodities that are difficult to maintain in new conditions because they are easily damaged. An effective effort to prevent deterioration of food quality during storage is by coating it using nano chitosan. The effectiveness of nano chitosan is influenced by particle size which related to the ratio of chitosan and STPP (sodium tripolyphosphate). This study aimed to determine the effect of nano chitosan coating with the addition of different ratios of chitosan and STPP and the appropriate ratio of chitosan and STPP on nano chitosan as a coating to maintain the quality of shallot bulbs (Allium ascalonicum L. var. Bauji). This study used a completely randomized design (CRD) method with four treatments and five replications. The treatments of this research were P0= Control, PI= Nano chitosan ratio of chitosan: STPP 1:3, P2= Nano chitosan ratio of chitosan:STPP 1:4, and P3= Nano chitosan ratio of chitosan:STPP 1:5. The variables of this study were the percentage of damage, the percentage of diameter shrinkage, weight loss, color, hardness, and moisture content. Data were analyzed using the ANOVA test and continued with the DMRT test. The application of nano chitosan coating on shallot bulbs could reduce damage, shrinkage of tuber diameter, weight loss, color, hardness, and decrease in water content better than the control treatment. The best results were shown by treatment P3 (1:5) with a percentage of damage of 8%, diameter shrinkage of 20.20%, weight loss of 18.40%, total color change of 54.45, hardness of 226.23 N, and a decrease in water content of 4.65% at the final water content of 79.09%.

Abstract

Klanceng honey is a type of honey produced by stingless bees. The characteristics of klanceng honey are a liquid texture and a more sour or bitter taste. The content of honey is influenced by the honey's food source, which can be seen from the pollen contained in the honey. Identified pollen can be used to indicate the characteristics of the plants that serve as bee food sources. The purpose of this study was to determine the diversity of pollen sources in klanceng honey from Penggung Village, Boyolali Regency; Kebonrejo Village, Magelang Regency; Ceper Village, and Ngemplak Village, Klaten Regency, which can be used to identify plants that serve as bee food sources and be used to label honey based on its food source. The sampling method used exploratory sampling with purposive sampling. The pollen analysis method used acetolysis. Data analysis used descriptive analysis. The results of melisopalinology showed that there were 26 plant pollen families contained in the four klanceng honeys, with coconut (Cocos nucifera) pollen being the most dominant. Klanceng honey from Ceper and Kebonrejo villages is monofloral, while honey from Penggung village is bifloral, and honey from Ngemplak village is multifloral. The conclusion of this study is that the plant diversity of klanceng bees' food sources is diverse.

Abstract

Indonesia's renewable energy penetration (12.3% in 2022) lags significantly behind 2030 targets (19-23%), with Cilegon City facing 1,167 unelectrified households and rising waste generation. This study assessed renewable energy development potential through LEAP-based electricity demand modeling (2023-2033) and technical-economic evaluation of solar photovoltaic and Refuse-Derived Fuel (RDF) systems. Meteorological and waste generation data informed engineering calculations and financial feasibility analysis. LEAP projections indicate residential electricity demand reaching 728.1 MWh per household by 2033, driven by 13.9% population growth. Off-grid solar PV systems demonstrate viability with Rp. 5,774/kWh levelized cost for unserved households. The proposed UPTD 3 Merak RDF facility shows strong economics: 22 tonnes/day capacity, 2-year payback, Rp. 12.5 billion NPV, and 3.01 benefit-cost ratio. Findings reveal that institutional rather than technical barriers impede deployment, highlighting needs for standardized subsidies, clarified jurisdictional frameworks, and municipal-utility partnerships. This research advances urban renewable energy planning by integrating bottom-up energy modeling with localized assessments, providing replicable frameworks for Indonesian cities pursuing energy transition and environmental sustainability goals.

Abstract

Steryl Glucosides (SG) are compounds produced from the processing of Fatty Acid Methyl Ester (FAME). SG compounds are obtained from the FAME filtration process using filter aid media. The filtering process produces residue in solids mixed with SG compounds (residual cake SG). Previous studies have shown that SG has a high calorific value and good combustion characteristics. However, the research is still on a laboratory scale. Another study states SG has a high energy density due to its characteristics, which include a long hydrocarbon chain. These make SG very potential to be utilized as a secondary co-firing fuel in boilers. Implementing co-firing could minimize coal consumption and lead to a reduction of carbon emissions. Furthermore, several studies found that co-firing could increase the boiler efficiency and reduce the fuel cost. This study aims to determine the effect of the residual cake co-firing ratio on the combustion, efficiency, and fuel cost of the stoker boiler. The research was conducted directly on the stoker boiler with a ratio of residual cake SG 5 wt%, 10 wt%, and 15 wt%. Based on the trial, increasing the residual cake SG ratio will improve the boiler combustion, increase efficiency up to 8%, and reduce the fuel cost.

Abstract

Anggrek Cymbidium ensifolium merupakan anggrek terrestrial dengan ciri bunga berwarna kuning corak merah. Keindahan anggrek tersebut menyebabkan masyarakat melakukan eksploitasi yang dapat mengancam kepunahan, sehingga diperlukan upaya pelestarian salah satunya secara ex situ dengan budidaya. Proses budidaya disesuaikan dengan kondisi alamnya yaitu menggunakan bahan alam sebagai pupuk alami atau organik. Bahan alam yang dapat digunakan dalam pembuatan pupuk adalah air kelapa dan air cucian beras. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk organik cair (POC) berbahan air kelapa dan air cucian beras dengan konsentrasi berbeda terhadap pertumbuhan anggrek C. ensifolium. Metode yang digunakan adalah ex situ dengan menanam menggunakan polybag dengan medium tanah: sekam: sekam berambut = 1: 1: 1 dan mikoriza 15 gr/tanaman di kebun percobaan menggunakan rancangan acak lengkap dengan satu faktor berupa konsentrasi POC 0%, 15% dan 30%. Metode analisis data menggunakan ANOVA dan DMRT. Hasil penelitian menunjukkan POC berbahan air kelapa dan air cucian beras berpengaruh meningkatkan pertumbuhan C. ensifolium. Pupuk organik cair 30% merupakan konsentrasi optimal untuk panjang tunas, panjang dan lebar daun. Kebaruan penelitian ini adalah digunakannya kombinasi air kelapa dan air cucian beras sebagai bahan dasar pembuatan pupuk dan pada konsentrasi 30% meningkatkan pertumbuhan anggrek.
