Published: June 2022

Introduction Rhizarthrosis is a common cause of pain and impaired function of the hand. Most patients present an excellent response to the conservative treatment, although a small percentage requires a surgical procedure due to the persistence of symptoms. Different surgical procedures have been described; however, there is still no consensus in the literature regarding the superiority of one technique over the others.

Objective To evaluate the clinical and radiological results of patients with a diagnosis of rhizarthrosis in stages 2 to 3 of the Eaton-Littler classification, submitted to arthroscopic hemitrapezectomy and suspension with Mini TightRope (Arthrex, Naples, FL, US).

Materials and methods We conducted a retrospective evaluation of the clinical and radiological results of patients operated on through the technique proposed in Clínica INDISA, in Santiago, Chile, between 2017 and 2019. The pre- and postsurgical assessments were performed using the visual analog scale (VAS) for pain, the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and the Kapandji score. The state of the articular cartilage was also evaluated intraoperatively according to the Badia classification.

Results A total of 12 patients (3 men and 9 women) met the inclusion criteria. Their mean age was 56 years, the mean duration of the follow-up was of 21 months. There were 7 patients in stage 2 and 5 in stage 3 according to the Eaton-Littler classification. Intraoperatively, there were 6 patients in stage II and 6 in stage III of the Badia classification. The mean preoperative score on the Kapandji index was of 3.6, and the mean postoperative score was of 9. The mean preoperative score on the VAS was of 8.8, and the mean postoperative score was of 1.2. The mean preoperative score on the DASH was of 33.3, and the mean postoperative score was of 4.7.

Conclusion Arthroscopic and suspension hemitrapezectomy with Mini TightRope for the treatment of stage 2-3 rhizarthrosis is a minimally-invasive, reproducible technique, effective in reducing pain and improving function, with sustained effects on the short and middle terms (6 to 36 months).

Authors: Valverde-Vilamala D. , Sala-Pujals A. , Cebamanos J. , Dominguez-Font E.
Published: June 2022

Introduction Acrometastases are extremely rare in the hand, with a prevalence of around 0.1% according to the literature. They are normally associated with advanced tumor stages, especially in lung cancer. The present article shows the experience of our center in the management and treatment of these pathologies.

Materials and Methods We report a series of 9 cases treated between 1992 and 2020 in the hand and wrist. Data regarding the primary tumor, the target organ, and survival are analyzed. A review of the cases of acrometastasis reported in the literature is also carried out, emphasizing in how many of then the acral lesion was the first sign of an unknown tumor.

Results Acrometastases predominantly affect male patients aged around 60 years, and the primary tumor that is the cause in most cases is lung cancer, with a very low survival rate after the diagnosis (of approximately 8 months).

Discussion and Conclusions In cases of acral lesion of non-traumatic origin, acrometastases should be considered, especially in patients who have a known primary tumor. In the present series, there were three cases in which the acrometastases were the first sign of a tumor in the patient, and in one of them it was initially treated as whitlow. In the literature, in approximately 50% of the cases, acrometastases are the first sign of the presence of a tumor.

Once diagnosed, multidisciplinary medicosurgical treatment is essential to improve the patient's function and pain as much as possible.

Authors: Lerma Eva Guisasola , Garcia Francisco Javier Lucas , Caraballo Alberto Márquez , Royo David Santosjuanes
Published: June 2022

Injuries to the triangular fibrocartilage complex (TFCC) can lead to instability of the distal radioulnar joint (DRUJ). In fact, they are the most frequent cause of it. But, in other cases, depending on the type of injury, the DRUJ remains stable. This will condition different types of treatments, from conservative management to the different options of surgical treatment. Since a controversy persists regarding the management of these lesions, our purpose is to disclose the foundations of the rehabilitation treatment and propose an algorithm of treatment according to the different types of injuries and their repairs.

Noise and signal as ground and figure: Emergence and interference in media ecologies
Authors: Castro Vinícius Portella
Published: June 2022

This paper proposes an interdisciplinary and generative understanding of noise that can be useful for thinking critically about art across different media ecologies. This notion of noise would be the counterpart of an intensive concept of information, such as the one presented by Gilbert Simondon. Unfolding a remark made by that author, the paper proposes three distinct notions of noise, as correlated to “pure chance”, “form”, and “information”. The noise of “pure chance” describes events of chaotic disruption and interference. The noise of “form” describes an index of the materiality and historical contingency of any transmission. The noise of “information” describes the irreducible margin of indeterminacy that is present at every layer of informational transmission and reception. An artwork created by Nam-June Paik is taken as a concrete demonstration of these three different kinds of noise. More generally, following sound theorist Aden Evens, an argument will be made for a speculative understanding of the signal in artistic practices as an emergent configuration from a ground of noise. To expand this idea for all media, we will explore the figure–ground relationship in the philosophy of Simondon as a scheme for the generation of forms from latent structural potential in a field. The work of Cécile Malaspina is used throughout the paper to clarify some confusions around the concept of noise and lay down the groundwork for fertile and rigorous interdisciplinary research across different media. The ambiguity of the concept of noise should not let us turn it into a night where all cows turn to greyscale. Instead, we should regard noise, in its distinct modes, as a marker of the granularity, speed, and resolution of any actual transmission and reception of information.

Patient-centred medicine is a healthcare approach that focuses on patients’ wants, needs and preferences. An obstacle to implement patient-centred medicine is the difficulty of obtaining data that is relevant and representative of the whole society. In 2019, the Spanish Society of Cardiology highlighted eight trends that would exert a determining influence on the future of cardiology: “demographics”, “economic environment”, “political environment”, “citizens’ expectations”, “incorporation of women”, “technological innovation”, “health levels and cardiovascular risk factors” and “healthcare organisation and management”. In order to assess these trends from a pacient-centred approach, the aim of this study is to evaluate the opinions of the individuals who are part of Spanish society, regarding the eight trends identified by the Spanish Society of Cardiology, using natural language processing tools to analyse the communications expressed by citizens in digital ecosystems and official channels of communication. We analysed communications published between 2007 and 2019. Natural language processing identified 17 areas of opinion that support the eight trends. We evaluated the impact of each area of opinion based on the standard metrics of online reputation: presence, emotion and reach. Thus, 257,456 communications were analysed. The most relevant trend was “healthcare organisation and management” (54% of the total impact), followed by “health levels and cardiovascular risk factors” and “demographics” (14% and 10%, respectively). The least relevant trend was “citizens’ expectations” (1%). Within the areas of opinion identified, the one with greatest impact was “the cardiologist” (16% of the total impact). In conclusion, the results of this research show that natural language processing tools are a useful tool for patient-centred medicine. The high impact associated with the cardiologist’s role, together with the low impact observed for “citizen’s expectations” show that Spanish citizens identify the cardiologist as the leading figure regarding their cardiovascular health.

Published: June 2022

Quantum conductance, known as Sharvin point contact, has been extensively investigated in many electronic devices, including diodes, transistors, and switches, especially in conductive filaments-based memristors. Quantum conductance with one or multiple atoms point connection can overcome the limitations of scaling and operating speed of nonvolatile multiple memory, logic device, and brain-inspired computing systems. However, because of the instability of the atomic arrangement in the one/multiple atoms connection in a conductive filaments-based memristor, it is a great challenge to maintain quantum conductance states for a long time. Here, we demonstrate that the stable long-time retention of multi-level quantum conductance states can be realized in Mott insulator vanadium dioxide with a highly oriented crystalline texture. According to in situ transmission electron microscope, conductive atomic force microscope, and detailed energy band analysis results, it is proposed that the grain boundaries act as reservoirs for oxygen vacancies and confine the oxygen vacancy diffusion in the narrow grain boundaries due to the higher bulk diffusion barrier. Our approach is extremely crucial for realizing quantum conductance-based electronic devices, such as multi-level and high-density storage and neuromorphic computing.

Published: June 2022

We report on a multi-photon source based on active demultiplexing of single photons emitted from a resonantly excited GaAs quantum dot. Active temporal-to-spatial mode demultiplexing is implemented via resonantly enhanced free-space electro-optic modulators, making it possible to route individual photons at high switching rates of 38 MHz. We demonstrate routing into four spatial modes with a high end-to-end efficiency of ≈  79% and measure a four-photon coincidence rate of 0.17 Hz mostly limited by the single-photon source brightness and not by the efficiency of the demultiplexer itself. We use the demultiplexer to characterize the pairwise indistinguishability of consecutively emitted photons from the quantum dot with variable delay time.
Origin of uniaxial magnetic anisotropy in MnAlCx: A first-principles study
Authors: Islam Riyajul , Alam Aszad , Borah J. P.
Published: June 2022

Exploring the thermodynamically metastable L10-ordered τ-MnAl alloy and its intrinsic magnetic properties are of great importance for its potential candidature as rare-earth-free permanent magnets (PMs). Here, based on first-principles calculations, we present a comprehensive investigation of the intrinsic magnetic properties of MnAlCx. The interstitial C-doping is demonstrated to have a substantial influence on the uniaxial magnetic anisotropy energy Ku, making MnAlCx appealing for PM applications. We predict a substantial enhancement in Ku of up to 2.30 MJ/m3 for x = 1, which is roughly 35% larger than that of pristine MnAl. The atomic resolved and orbital resolved Ku, as well as the perturbation theory energy analysis, may be used to understand the cause of this enhancement. Using second-order perturbation theory and electronic structure analysis, we show that increased Ku is caused by a complex interplay between tetragonal and orbital distortion due to the C-doping. These findings can aid in the efficient and inexpensive design of PM materials.

Published: June 2022

In recent years, the field of flexible electronics has become one of the cross-disciplinary research hotspots, attracting worldwide attention and making rapid advances. So far, there has been plenty of research on the use of two-dimensional (2D) materials in flexible electronics, including graphene, transition metal dichalcogenide, and so on. In this work, we successfully prepared quasi-one-dimensional (Q1D) Nb2Pd0.73S5.97 superconductors on flexible paper by mechanical friction and systematically studied their physical properties at low temperatures. Superconductivity with transition temperature (Tc) ∼ 6.05 K by Meissner effect was observed in Nb2Pd0.73S5.97 wires coated on flexible paper, and a resistance drop at 4.80 K was confirmed in electrical transport measurements. The lower critical field (Hc1) of coated paper shows anisotropy effect under parallel and perpendicular magnetic fields, exhibiting a 2D-like feature, unlike the bulk Nb2Pd0.73S5.97 fibers. Our work provides a broader platform for the application of low-dimensional materials in flexible functional devices.

Published: June 2022

Background Medicare, the health insurance system underpinning free healthcare in Australia, introduced free telehealth items in 2020 in response to the coronavirus disease 2019 (COVID-19) pandemic. Their uptake among healthcare providers was significant, including among general practitioners and sexual health services. Here, we report people’s experiences of accessing sexual and reproductive health (SRH)-related care via telehealth collected as part of a survey exploring the impact of COVID on SRH health. Methods This study utilises qualitative data from two online surveys conducted in 2020. Surveys were advertised through social media and professional and personal networks. Anyone aged ≥18 years and living in Australia was eligible to participate. Respondents were asked whether they accessed care for their SRH via telehealth. A free-text question asking for further detail about their experience was analysed using content analysis. Results A total of 114/1070 respondents (10.7%) accessed healthcare services via telehealth for SRH-related reasons within the previous 4 weeks. Three themes were identified from 78 free-text comments: (1) accessibility and convenience of telehealth; (2) appropriateness of telehealth for SRH issues; and (3) connecting and communicating with clinicians via telehealth. Respondents had a wide range of experiences. Telehealth improved access to services for some participants, and it was appropriate for some, but not all SRH issues. Difficulties connecting with clinicians on both an interpersonal and technical level was a key barrier to a satisfactory patient experience. Conclusions Telehealth can offer a viable alternative to face-to-face care, providing patients can overcome key connection and communication barriers.
Structure of human NADK2 reveals atypical assembly and regulation of NAD kinases from animal mitochondria

Published: June 2022

All kingdoms of life produce essential nicotinamide dinucleotide NADP(H) using NAD kinases (NADKs). A panel of published NADK structures from bacteria, eukaryotic cytosol, and yeast mitochondria revealed similar tetrameric enzymes. Here, we present the 2.8-Å structure of the human mitochondrial kinase NADK2 with a bound substrate, which is an exception to this uniformity, diverging both structurally and biochemically from NADKs. We show that NADK2 harbors a unique tetramer disruptor/dimerization

nimals (EMKA) and absent from other NADKs. EMKA stabilizes the NADK2 dimer but prevents further NADK2 oligomerization by blocking the tetramerization interface. This structural change bears functional consequences and alters the activation mechanism of the enzyme. Whereas tetrameric NADKs undergo cooperative activation via oligomerization, NADK2 is a constitutively active noncooperative dimer. Thus, our data point to a unique regulation of NADP(H) synthesis in animal mitochondria achieved via structural adaptation of the NADK2 kinase.
A study of linguistic manipulations of activating, seeking and creating common ground in intercultural business communication
Authors: Li Chengtuan
Published: June 2022

Previous studies on common ground (CG, for short) have mainly focused on its definition and functions in various daily interactions. Few studies explore the linguistic manipulations of CG in cross-cultural business interactions. This paper aims to fill in this gap by examining how sellers and buyers manipulate linguistic actions of activating, seeking and creating CG to make a deal. This study instantiates and develops Kecskes’ (2013) CG model. Based on qualitative analysis of data collected from email interactions between Chinese sellers and Australian buyers, I find that (1) Interlocutors often activate their core CG through manipulating frequency markers such as “again”, and epistemic markers such as “I knew”, “you know”, “might”; (2) Interlocutors seek core CG and emergent CG by manipulating epistemic markers such as “I’m sure”; (3) Interlocutors often bring the third party or element into the communication to create emergent CG by using question markers such as “you see?”, imperative markers such as “Do you understand!”, and narrative markers like “I tell you” and “once” or “before”; (4) The interpersonal manipulations of CG construction contribute to business integrity and reliability because the more efforts interlocutors make to activate, seek, and create CG, the more clarified and acceptable their business relations become in business communication. For the purpose of validating what I have found, I conduct a quantitative study of linguistic means of constructing CG in the Santa Barbara Corpus of Spoken American English (SBCSAE), and summarize the typical linguistic means of activating, seeking, and creating CG in various settings.
Investigation on rheological characteristics of magnetorheological shear thickening fluids mixed with micro CBN abrasive particles

Published: June 2022

The novel magnetorheological shear thickening polishing fluids (MRSTPFs) were developed by mixing micro cubic boron nitride (CBN) abrasive particles into traditional magnetorheological shear thickening fluids. MRSTPFs were constructed by uniformly fumed silica and polyethylene glycol as shear thickening fluids, carbonyl iron particles (CIPs) as ferromagnetic phase and CBN particles as abrasive phase. In this work, various MRSTPFs were prepared to explore their rheological characteristics. Sweeps of steady shear rate and dynamic shear frequency were conducted under different magnetic flux densities, respectively. A mathematical model was presented to explain shear rate variation with shear stress. The magnetorheological shear thickening mechanism was well described. The rheological experiment results have revealed that shear thickening effect was still existing in magnetic flux density. However, the increased magnetic flux density played a negative role on the shear thickening effect. Particle size optimization of CIPs was thus essential to maximize the shear thickening effect. On the other hand, with increased shear frequency, the viscoelastic feature of MRSTPFs was converted from linear to non-linear. It was found that the shear yield stress of the MRSTPFs was magnified with the stronger magnetic flux density and larger CIPs size. The investigation of rheological characteristics demonstrated that MRSTPFs could enhance polishing performance, which contributed to developing a high-efficiency and ultra-precision polishing process.

Published: June 2022

Objective. We investigated whether a recently introduced transfer-learning technique based on meta-learning could improve the performance of brain–computer interfaces (BCIs) for decision-confidence prediction with respect to more traditional machine learning methods. Approach. We adapted the meta-learning by biased regularisation algorithm to the problem of predicting decision confidence from electroencephalography (EEG) and electro-oculogram (EOG) data on a decision-by-decision basis in a difficult target discrimination task based on video feeds. The method exploits previous participants’ data to produce a prediction algorithm that is then quickly tuned to new participants. We compared it with with the traditional single-subject training almost universally adopted in BCIs, a state-of-the-art transfer learning technique called domain adversarial neural networks, a transfer-learning adaptation of a zero-training method we used recently for a similar task, and with a simple baseline algorithm. Main results. The meta-learning approach was significantly better than other approaches in most conditions, and much better in situations where limited data from a new participant are available for training/tuning. Meta-learning by biased regularisation allowed our BCI to seamlessly integrate information from past participants with data from a specific user to produce high-performance predictors. Its robustness in the presence of small training sets is a real-plus in BCI applications, as new users need to train the BCI for a much shorter period. Significance. Due to the variability and noise of EEG/EOG data, BCIs need to be normally trained with data from a specific participant. This work shows that even better performance can be obtained using our version of meta-learning by biased regularisation.
Persistence probabilities of mixed FBM and other mixed processes
Authors: Aurzada Frank , Kilian Martin , Sönmez Ercan
Published: June 2022

We consider the sum of two self-similar centred Gaussian processes with different self-similarity indices. Under the assumption of non-negative correlations and some further minor conditions, we show that the asymptotic behaviour of the persistence probability of the sum is the same as for the process with the greater self-similarity index. In particular, this covers the mixed fractional Brownian motion introduced in (Cheridito 2001 Bernoulli
7 913–34) and shows that the corresponding persistence probability decays asymptotically polynomially with persistence exponent 1 − max(1/2, H), where H is the Hurst parameter of the underlying fractional Brownian motion.

Published: June 2022

This investigation aimed to determine the physicochemical, proximate, and antioxidant results of a functional drink made from red and purple roselle with the addition of chitosan. Six drink formulations were prepared based on different ratios for red, purple roselle extracts and chitosan, respectively; C0 (30: 0: 0)%; C1 (0: 30: 0)%; F1 (20: 10: 0.5)%, F2 (10: 20: 0.5)%, F3 (20: 10: 1)%, and F4 (10: 20: 1)%. Functional drink samples were made by the pasteurization method at 90 °C for 15 minutes. The scavenging activity of 2,2-diphenyl-1-picrylhydrazyl (DPPH) was used to measure antioxidant activity. The resulting pH values ranging from 2.62 to 3.20. Moisture content ranging from 90.45 to 93.10 g/100 ml, ash content ranging from 2.20 to 3.44 g/100 ml, protein content ranging from 1.42 to 2.62 g/100 ml, fat content ranging from 0.22 to 0.48 g/100 ml. The scavenging ability on DPPH radical is the highest on F4 with the addition of 1% chitosan ranging from 18.08% to 34.10% and the smallest at C0 is 10.05% to 27.15%. The results show that the addition of chitosan can improve the physicochemical, proximate, and antioxidant properties in functional drinks from red and purple roselle extracts.

Development of ruminant livestock requires to a stable availability of feed because feed is a determining factor for the continuity and success of businesses in livestock production The aimed of this study was to analyses the potential for beef cattle development based on the availability of forage from agricultural waste in the eastern region of West Java province. The sample locations were taken from 3 regencies based on low of population density per unit of agricultural land, namely Majalengka, Indramayu, and Ciamis Regency. Time series data on land use and agricultural waste production at the Regency’s from 2015 to 2019 were used in this research. Data analysis used LQ (location question) and IDD (carrying capacity index). The results showed that the total sub-Regency’s from 3 Regency’s was 84 sub-districts, where there were 24 sub-districts that have LQ> 1, indicates that these sub- districts were the base area for beef cattle development. Furthermore, based on the IDD analysis, all of the 24 sub-districts have IDD values > 2, which means that based on the availability of forage from agricultural land, it was in the safe category to increase of the beef cattle population. The twenty-four sub-districts in West Java Province can serve as the basis for the development of beef cattle that need to be considered by farmers and the local government, namely increasing production (especially quality forage feed even though the availability of agricultural waste is sufficient), productivity and efficiency (marketing infrastructure) supported with policy government.

Published: June 2022

Beef cattle farming is a source of income preferred by the people of Kediri Regency to fulfill their daily needs. Various components related to beef cattle business in Kediri Regency need to be assessed to understand the real facts related to the business. This study aims firstly to analyze the density cluster of cattle and the second perception of beef cattle breeders in Kediri Regency regarding the components of strength, weakness, threat, and opportunity in the beef cattle business. The research was conducted in June - December 2019. Data collection was carried out through a survey of 150 breeders and FGD (Focus Group Discus) involving 15 experts was conducted. The data obtained were then analyzed by using the K-means cluster. The results of the first study regarding the density level of cluster 1 (one) solid category with successive central values (13239, 7658, 88190, 4759), there are 6 (six) districts. Cluster 2 (two) with moderate category with central value (9966, 1870, 59872, 3618) totaling 17 (seventeen) districts. Cluster 3 (three) categories rarely consist of three districts. The second result is based on the perception that the strength component of the government support aspect must be optimized, small amount of farmer capital became the weakness aspect of the business. The increasing demand for beef was the opportunity aspect. The rampant slaughter of productive female cattle was the threat aspect of this business. Based on the results of the K means cluster analysis, it is concluded that the beef cattle business in Kediri Regency is very potential to be developed because of the dominance of the area in clusters 1 and 2. The Kediri Regency Government and its stakeholders are actively involved in the success of the beef cattle breeder business. The results show that the strength component of the government support aspect must be optimized.

Published: June 2022

The use of wheat flour as a raw material in the manufacture of other food products will cause dependence on imports of wheat flour in Indonesia. One of the opportunities to suppress wheat imports is to develop local flour, including cassava flour. To be applied further, one of the characteristic parameters that can be observed from local flour is its viscosity profile. This study object to determine the effect of several additives on the RVA (Rapid Visco Analysis) profile of cassava flour. Several modifications were made by adding several types of additives, including: salt, sugar, developer, emulsifier and various hydrocolloids using various concentrations of 0.5 to 4%. Based on the results of the analysis, the presence of types and variations in concentration resulted in varying characteristics based on the results of the RVA analysis. With increasing levels of guar gum and xanthan gum, the peak viscosity increases. However, it is different with the addition of concentration in the developer and malto dextrin forms a peak at the concentration of additives added. These results can be used further as consideration for the formulation process and application of further processed products.

Single-phase induction motors are a type of electric machine that are widely used in people’s lives due to it has advantages such as lower prices, simple maintenance and construction. However, the single-phase induction motor also has a weakness, which is difficulty in setting up the rotation. The rotation setting of a single-phase induction motor can be affected by changes in the input frequency and changes in the input voltage. In this study is to design the control of a single-phase induction motor in a commonly used fan. The speed of the single-phase induction motor is regulated based on the number of visitors, using artificial intelligence namely fuzzy logic. The fuzzy logic controller can be group visitors to the room to determine the speed of the fan. The visitors are divided into three groups, namely “many” to indicate the maximum speed, “medium” for medium speed and “few” for low speed. Therefore, this research may contribute as an energy-saving solution using artificial intelligence.

This study assesses the sustainability of indigenous cattle production (Jabres Cattle) during the COVID 19 pandemic in Brebes Regency, Indonesia. The sustainability of Jabres cattle production is considered from the aspects of production, socio-economic, and environmental aspects. The study was conducted on 64 Jabres farmers in 5 sub-districts (Ketanggungan, Bantarkawung, Banjarharjo, Larangan, and Salem). Respondents were taken using a simple random sampling method and data was taken using online questionnaires. The collected data were analyzed using descriptive statistics. The indigenous cattle farmers in Brebes Regency have a long experience as beef cattle farmers (10.7 years on average) with an average ownership scale of 7 heads. During the pandemic, there was an increase of 54.7 percent of farmers who felt it was difficult to get cattle breeds compared to before the pandemic. The number of farmers who found it difficult to get forage also showed an increase of 36 percent compared to before the pandemic. Likewise, an increase in the number of farmers (75 percent) felt that it was increasingly difficult to sell beef cattle, which resulted in not making it easy for profits. However, the COVID 19 pandemic can encourage all farmers to pay more attention to the cleanliness of cowshed and the cage environment. Most of the indigenous cattle farmers (89 percent) remain committed to continuing their business despite difficulties in obtaining calves, feed, and selling cattle. Farmers still have confidence that the difficult situation will pass, and demand slaughter cattle will recover.

So, the perspective that focuses on handling during and after a developing disaster must be changed. In this matter, the government establishes the Desa Tangguh Bencana (Destana)/Disaster Resilient Village Policy. With various activities with the community involvement, the risk and impact of disasters can be eliminated because the community has been trained to prepare for disasters. The research aimed at determining the types and forms of community participation in disaster management in Gondoriyo Village Administration, Ngaliyan Sub-District, Semarang City. Gondoriyo Disaster Resilient Village is one of the pioneers in Semarang City, which started from the volunteers of the Disaster Preparedness Group. The research results show that the type of community participation is direct; either in a kind of money, support or their involvement in decision making. Their participation is in the form of thoughts, energy, skills, and property as well. It indicates that the awareness of Gondoriyo community to actively participate in prevention, preparedness, disaster risk reduction and capacity building efforts for the post-disaster recovery. It is proven later that Gondoriyo Village Administration has received the title as the Intermediate Disaster Resilient Village. However, what must be improved is how the disaster management programs are integrated into village administration development plans; particularly in relation to assistance to increase capacity and funding as well. Therefore, its existence can be maintained and sustainable.

Palm oil waste management must be done as a form of implementing zero waste palm oil industry. Oil palm Empty Fruit Bunches (EFB) are one of the solid wastes produced from processing Fresh Fruit Bunches (FFB). PT ABC manages EFB waste by utilizing it as organic fertilizer with the mulching method. EFB is organic material containing nutrients and can improve soil physical properties when applied to plant cultivation areas. This study was conducted to determine the impact of EFB application on plantation land on the level of oil palm production and the potential for pests that can be caused and to analyze the implementation of EFB application at PT ABC, Bengkulu. The study method used is descriptive, using primary data obtained through observation, interviews, literature studies and documentation, and secondary data obtained by identifying organisms at the spot of EFB application and observing oil palm plants for symptoms of horn beetle attack. Then, data analysis was carried out using descriptive statistical methods and SWOT analysis methods. The results showed that the application of EFB with a single layer mulching method at PT ABC could reduce the risk of the appearance of horn beetle pests and could potentially increase the productivity of oil palm plants, although not too high. PT ABC has the opportunity to carry out a comprehensive EFB application to have a good impact on the company by considering the recommended SWOT analysis strategy.
