Abstract
The study aimed to investigate the response of superior rice variety (Inpari 33) to the combined fertilization of inorganic fertilizers with organic and biosilica fertilizers to its growth and productivity. Field activities carried out in rice fields at Sidowaluyo Village, Sidomulyo District, South Lampung Regency, Indonesia. The experiment was arranged in a Randomized Block Design with four replications with the treatments were: A. Control (without liquid biosilica or organic fertilizer application); B. Liquid biosilica sprayed on the plants at 21 and 42 days after planting (DAP), 2 l/ha/application; C. Liquid biosilica applied at 21 and 42 DAP, 4 l/ha/application; D. Liquid organic fertilizer applied at 40 and 47 DAP, 1 l/ha/application; and E. Liquid organic fertilizer applied at 40 and 47 DAP, 2 l/ha/application. Results showed that organic liquid fertilizer application at 40 and 47 DAP 2 l/ha/dose increases the number of panicles, grains, rice yields, and straw weight. The application of liquid organic fertilizer increased rice yields by 9.9 % (from 7.10 to 7.88 tons/ha) and rice straw weight by 13.23% (from 11.15 to 12.85 tons/ha) compared to the control. However, the application of biosilica could not increase rice yields or straw weight.

AbstractVariety improvement program of citrus in Indonesia has still been prioritized, therefore, characterization and identification of varieties within and/or among citrus species are absolutely required in order to obtain desired varieties based on market demand needs. The aim of this research was to determine morphological characteristics, flowering periods, and the genetic relationship of four citrus species. This study was carried out at Indonesia Citrus and Subtropical Fruit Research Institute (ICISFRI). A total of 12 varieties derived fromCitrus reticulataBlanco,Citrus sinensisL. Osbeck,Citrus aurantifolia(Christm.) Swingle), andCitrus lemon(L.) Burm. F was used for morphological description. The genetic relationship was evaluated by morphological and molecular analyses using Inter-simple Sequence Repeat (ISSR). The result showed that variations of morphological characters were identified either within or among four citrus species.Citrus reticulataBlanco had the highest physiochemical contents. In terms of flowering periods, varieties that belong toCitrus reticulataBlanco, andOrtaji(Citrus sinensisL. Osbeck) required 9 to 11 days for fully blooming after flower bud; whereasMontaji(Citrus limon(L.) Burm. F) andNimas(Citrus aurantifolia(Christm.) Swingle) needed 16 days. In both morphological and molecular analyses, 12 varieties were classified into two main clusters, however, some differences were found between the two dendrograms. The genetic relationship of four citrus species based on similarity coefficient ranged from 1 to 25 (morphological analyses) and 0.62 to 0.90 (ISSR marker), respectively. The highest genetic relationship derived from both analyses was performed byKrismaversusMonita, andKrismaversusOrlinda Kuning, respectively. Morphological analyses are still needed to complement molecular analyses in citrus classification in order to produce desired new citrus varieties in order to create sustained citrus agribusiness in Indonesia.

Abstract
Despite the fact that lime and lemon groups have been collected as germplasm in the Indonesian Citrus and Subtropical Research Institute, a limited amount of research has been conducted on the identification and evaluation of these species. This study aimed to evaluate the morphological, anatomy, genetic polymorphism, and relationships among 16 lime and lemon accessions based on six ISSR markers. The research was conducted at Punten Experimental Garden, Batu, East Java, Indonesia from January to December 2021 in order to describe the morphology and anatomy characteristics. The results showed that 109 DNA bands were considered for the ISSR analysis, of which 88.1% were polymorphic. The dendrogram showed that the accessions were separated into two main groups at a coefficient of 0.62. The first group was divided into three clusters, i.e. A, B, and C consist of introduced varieties, most of the local lemons, and limes, respectively. The second group has only a single member (Limo Kwit). The closest genetic distances were between Cai Kahuripan and Lemon Jumbo (88.1%) and Uereka with Lime Bearr (88.3%). In contrast, the lowest ones were Montaji with Lemo Kwit (52.9%) and Lemon Swanggi with Jari Buda (51.2%). In general, genetic traits reflected in existing clusters contributed to differences in their morphology and anatomy of plants. It is assumed that the local accession of Lemo Kwit is a hybrid of subgenus papeda, so it is separated from the lime and lemon groups that belong to Cluster II. This finding is very useful for breeding programs in Indonesia.

Abstract

Pyricularia grisea (blast disease) and bacterial diseases resulted rice yield loss. Tolerant varieties and seed-dressing are expected reduces the disease. This research was aimed to define the effect of tolerant varieties and seed - dressing to the incidence of blast and bacterial diseases. Research was conducted at endemic area in Yogyakarta Indonesia from November 2021 to March 2022. The experiment was designed in randomized block with 2 factors and 4 replications. Factor 1 was variety: Inpari 32 HDB, Inpari 45 Dirgahayu and Inpari 48 Blas as tolerant variety and Sunggal as common variety. Factor 2 was seed treatment: Pseudomonas fluorencens solutions, consortia of antagonist fungi and bacterium, and fungicide Trisiklazol 225 g l−1 and Azoksistrobin 75 g l−1. Results showed that tolerant varieties was significantly reduced blast and BLB. The highest incidence of blast and bacterial diseases were found at Sunggal, while not found at Inpari 45 Dirgahayu and Inpari 48 Blas. Meanwhile, bacterial diseases was found at low level at the 3 tolerant varieties. Bacterial disease found in this research was BLB (Bacterial Leaf Blight), BRS (Bacterial Red Stripe) and BLS (Bacterial Leaf Streak). Result also showed that seed treatment did not affect the reduction of blast and bacterial disease. At other site, highest yield (10.18 ton ha−1) was obtained from Inpari 32 HDB which was treated with consortia of antagonist fungi and bacterium. Hence, the 3 tested tolerant varieties was promising to be established at the endemic area in the agro ecosystem of irrigated rice in Yogyakarta Indonesia.

Abstract
Authentic Luwak arabica coffees are expensive and available in the market in a very limited quantity. For this reason, feeding Luwak arabica coffees at a cheaper price is becoming popular for substitution the authentic Luwak arabica coffees in the specialty coffee market. In the form of coffee powder, it is quite hard to visually inspect the difference between authentic and feeding Luwak arabica coffees. In this study, we proposed a low-cost and eco-friendly approach to discriminate between authentic and feeding Luwak arabica coffees. This method works by preparing aqueous Luwak coffee samples using hot-distilled water. The absorbance data of a total of 200 samples of authentic and feeding Luwak arabica coffees in the wavelength of 190-1100 nm were obtained using a benchtop UV-visible spectrometer. Chemometrics using both unsupervised and supervised methods were demonstrated. The results confirmed authentic Luwak arabica coffees could be well discriminated from feeding Luwak arabica coffees with sensitivity, specificity, and accuracy of 100% could be obtained. This method could be easily implemented in the specialty coffee market to avoid Luwak coffee fraud.

Published: May 2023

Abstract
There is a lack of information regarding the characteristics and potential of specialty corn in Indonesia, resulting in its limited use as a raw material in the corn processing industry. Starches were isolated from four varieties of biodiversity-specialty corn (Srikandi Kuning, Srikandi Ungu, Pulut Uri, and Provitamin A), one line of specialty corn (Dent-type), and one imported corn from Argentina. The aim of this study was to gather data on the physicochemical and functional properties of Indonesian specialty corn starch, which is to be used as the base to increase the value of those biodiversity. Starch yields ranged from 34.30 to 49.22%. The starches met the SNI (Indonesian National Standard) requirements for both water content (6.90–8.72%) and white degree value (86.40–105.46%). There were variations in the starch contents of starches from 72.03 to 82.75%, and in the amylose contents from 6.32 to 31.47%. Starch granules showed oval and polygonal shapes with sizes ranging from 2.93 to 18.36 mm. Pasting profile and thermal properties showed the differences among the starches. The Dent-type corn starch had the lowest breakdown value of all the Indonesian specialty corn types, while imported corn starch had the lowest breakdown value of all the starches, showing the greatest stability during heating and stirring. In terms of peak temperature and enthalpy value, they ranged from 82.9°C to 92.71°C and from 85.94 to 551.93 J/g. The present study is expected to provide information about characteristics of Indonesian specialty corn starch, then subsequently, it can be utilized by the food industry, and increase the value of our national biodiversity.

Abstract
Food processing technology to produce meals that ready to eat is one alternative way to reduce damages of horticulture product. To ensure the carrot chips are still suitable for consumption, the information of the shelf life of this product is needed. Method to determine shelf life of carrot chips is by using Accelerated Storage Studies (ASS) with Arhenius approach using 7°C, 15°C, 25°C and 30°C as acceleration condition. In an empirical research, carrot chips were packaged using aluminum foil with thickness of 50 μm, 80 μm and 100 μm and stored at 30°C, 37°C and 45°C. The products were evaluated every weeks for eight weeks of storage. Parameters observed in both studies were moisture content, crispness and free fatty acids (FFA). Result showed that aluminum foil with thickness 100 μm maintained quality of carrot chips during storage. The product packaged in aluminum foil thickness of 100 μm had the longest shelf life in terms of FFA parameter using the acceleration method reaching 66.99 to 103.21 days.

Published: May 2023

Abstract
Mangrove ecosystems are crucial to the management of coastal resources, particularly those of small islands. The destruction of mangrove forests is brought on by mangrove logging and the transformation of mangrove land into aquaculture areas. This is due to the economic demands of the local community. The government has made numerous efforts to protect and rehabilitate mangroves, including mangrove restoration in accordance with Regulation No. 03/MENHUT-V/2004 of the Minister of Forestry and Environment. However, its implementation has not been effective, especially if it is tied to the convention on biodiversity and the Sustainable Development Goals; the protection of mangroves continues to face numerous obstacles. The research methods employed are both empirical and normative. The results of this study indicate that the convention on biodiversity, which is the actual basis for mangrove rehabilitation, has not protected the area because (1) spatial planning does not accommodate mangrove protection; (2) public awareness is low; (3) law enforcement is ineffective; and (4) the problem of mangrove rehabilitation exists.

Abstract
This study aims to determine how Malioboro tourists behave towards the government’s policy of forcing people to walk in the Malioboro area. In addition, this study wants to find out whether the habit of walking in Malioboro can make people have green behavior that can be applied in everyday life. The conceptual framework is proposed using the theory of planned behavior (attitudes, subjective norms, and perceived behavioral control). The sample comprises 151 respondents from Malioboro tourists who visited during the last six months and was analyzed through partial least squares-based structural equation modeling. The results demonstrate that personal desire drives intention toward green behavior (perceived attitude and behavioral control). However, it turns out that humans also need external factors to make them inclined toward green behavior in the form of coercive regulations from the government. According to predictions, coercive environmental policy has been proven to moderate the TPB theoretical framework towards intention towards green behavior.

Published: May 2023

Abstract
The Decree of the Minister of Forestry of the Republic of Indonesia, Number SK 398/Menhut-II/2004, dated October 18, 2004, converted the Maros Pangkep karst area to the Bantimurung-Bulusaraung National Park (Babul National Park). Karst and Babul National Park depend on rainwater absorbed by subsurface rivers. Babul National Park has integrated water management, although water supply and security are still threats. This study analyzes the harmonization and synergy of water policy with community requirements in the Maros-Pangkep Karst area, where residents rely largely on underground rivers. This study utilizes empirical legal research. (1) The Babul National Park manager distinguishes between the use of water as mass and as energy, and the surrounding community must seek for a permit for the latter. In the implementation process, the permission did not fully comply with the existing standards, notably the Minister of Environment and Forestry Number P.18/MENLHK/SETJEN/KUM.1/4/2019 governing the use of water and energy in wildlife sanctuaries, National Parks, Grand Forests, and Nature Tourism Parks. (2) Because legal enforcement hasn’t deterred forest destroyers, this will undermine forest conservation and the importance of forests in water management.

Abstract
Tourism is an alternative livelihood for people to earn income by utilizing the natural wealth around them. Natural ecosystems need to be conserved so that they remain balanced and can be utilized. These problems are what prompted the emergence of the idea of a green economy. The idea of a green economy aims to encourage the economic development of tourism while still preserving the environmental ecosystem. Therefore, the focus of the problem in this article is to examine the policy direction of green economy ideas in the regulation of tourism in Indonesia. The purpose of this study is to analyze the implementation of the idea of a green economy in the regulation of the tourism sector in Indonesia. Normative research methods are used with statutory and conceptual approaches to analyzing the regulations of the tourism sector in Indonesia. This research resulted in a novelty of draft regulations in the tourism sector that accommodate the idea of a green economy to become a reference for tourism actors to maintain environmental sustainability to realize sustainable tourism and update previous regulations that have not accommodated the idea of a green economy.

Abstract
This research is related to the Statistics of Riau Province, which noted that the poverty rate has increased from year to year in Rokan Hulu Regency. Poverty that afflicts 74.73 thousand people in Rokan Hulu is the responsibility of the state, including the regional government. The purpose of this study was to determine the strategy of regional government in preparing the Regional Government Budget in Rokan Hulu Regency in completing the mission. This type of research is a qualitative research with an empirical juridical approach. The data used is primary data in the form of interviews with informants and secondary data obtained from literature review in the form of legislation and related documents. It was found that the regional government strategy in preparing the Regional Government Budget to complete the mission in Rokan Hulu Regency was to include special programs for the poor. It takes the form of agricultural assistance, agriculture, plantations and so on. The problem is that some of these aids are not well targeted and there is weak supervision from the regional government. Therefore, it can be said that the regional government of Rokan Hulu has developed a strategy to complete the mission, but in its implementation there are no drawbacks, namely inappropriate assistance and the weakness of local government supervision.

Abstract

Objective. This study has aimed to evaluate the effects of toothbrushing on the wear behavior of two composites, three ceramic materials, and ceramic/composite interfaces. Material and Methods. Nanofilled (Filtek Ultimate), and nanohybrid composites (Spectra ST HV) were used for the repair of a hybrid ceramic (Vita Enamic), resin nanoceramic (Katana Avencia), and zirconia block (Katana Zirconia). Composites, ceramics, and ceramic/composite interfaces were examined before and after a period of one-month and one-year of toothbrush abrasion testing using non-contact optical profilometry and scanning electron microscopy (SEM). Data were analyzed by two-way ANOVA and Bonferroni correction. The statistical significance level was set at p < 0.05. Results. No difference was found between the surface roughness of the Vita Enamic, Katana Avencia, Filtek Ultimate, and Spectra surfaces after one month and one year of toothbrushing. Sa values in Katana Zirconia material were found to be significantly lower than those in the control group after one year of brushing. The surface roughness of the repair interfaces formed by repairing hybrid ceramic and resin nanoceramic CAD/CAM materials with nanofilled and nanohybrid composite materials was found to be similar after different brushing times. Conclusion. Vita Enamic, Katana Avencia, Filtek Ultimate, and Spectra materials can be preferred in clinical repair applications, since they exhibit similar wear behavior after brushing at different times. For the zirconia material, the repair interface had similar surface roughness as the ceramic and composite surfaces after one year of brushing. Periodic recalls and re-polishing may thus be necessary when these products are used clinically.

Authors: Tripathi Jayant Mani , Mallik Sanjeev Kumar 
Published: May 2023

Abstract
The present study is focussed on solving the relay coordination problem. Protection of microgrids is performed through the placement of directional overcurrent relays (DOCR). The efficacy of microgrid protection depends on coordination of all the DOCRs placed in the system. For this purpose, a number of optimization techniques have been employed by the power system researcher. In this paper, Grey Wolf Optimizer (GWO) is proposed for the protection coordination of DOCRs for different modes of microgrid operation. The proposed method is tested and validated on a 7-bus mesh system and a 9-bus radial test system. The proposed method has been compared with other meta-heuristic optimization approaches, namely Genetic Algorithm (GA), Artificial Bee Colony (ABC), Gravitational Search Algorithm (GSA), and Hybrid Particle Swarm Optimization Gravitational Search Algorithm (PSOGSA). Based on the obtained results, the GWO-based approach is very efficient in mitigating the problem of relay coordination as compared to other optimization techniques.
