This study' purposes are to synthesize molecularly imprinted polymer (MIP) with hydroxyethyl methacrylate (HEMA) and triethylene glycol dimethacrylate (TEGDMA) using p-xylene under ultraviolet curing at 405 nm for the recognition of hydroquinone (HQ) in aqueous medium. The template was extracted from the polymer with a mixture of methanol and acetic acid (9:1) by volume (v/v). The Fourier transform infrared (FTIR) spectrum of MIP (after wash) showed the absence of peak at the range of 840–860 cm−1, which represented the stretching outside the aromatic plane C–H at the para position (p-xylene). Field emission scanning electron microscope (FESEM) micrograph showed that the MIP had cavities compared to non-imprinted polymer (NIP). The MIP (MIP-Pxy) with ratio (monomer:crosslinker) 0.25 and 1.00% template gave the highest uptake of hydroquinone (HQ) in aqueous solution, which implied more specific recognition (highest KD value). The rebinding of HQ onto MIP-Pxy was best described by both isotherm (Langmuir and Freundlich) and kinetic model (pseudo-first and -second). The MIP was successfully synthesized using p-xylene, able to recognize HQ and was very selective to p-CP. Implication of the study, the synthesized MIP can be used for recognition and sensing materials for HQ and any similar molecules.

In the contemporary era characterized by globalization and swift democratic progress, Indonesia encounters distinctive challenges of rising political expenses. This article utilizes qualitative research methodologies to examine the consequences of increasing political costs on the dynamics of Indonesian democracy, specifically concerning accountability and financial support for political parties. The main findings suggest that the financial assistance to political parties in Indonesia has not adequately tackled the forthcoming challenges that Indonesian democracy may encounter. In contrast, political parties persist in facing challenges in accountability mechanisms for the funds they acquire. The provision of financial aid may be perceived as a feasible approach to mitigate the financial burdens associated with political campaigns. However, in the absence of adequate mechanisms to ensure transparency and accountability, there is a possibility of corruption and concerns regarding the scope of funding. This article further emphasizes the significance of political education as a fundamental obligation of political parties to uphold democratic efficacy. This study places particular emphasis on the ramifications of providing financial assistance to political parties for the future trajectory of Indonesian democracy. To ensure the continued progress of democracy in Indonesia and realize the “Golden Indonesia 2045” vision, stakeholders must possess a comprehensive comprehension of the matter and effectively tackle the obstacles that arise from the significant political expenses involved.

Students find it difficult to understand the material of chemical equilibrium. One of the efforts to overcome these student difficulties is to use a structured inquiry-based module equipped with three levels of representation. This study aims to determine the effect of using the module on students' mental models. This study used a posttest-only control design conducted in two schools. In the design, each school had two groups, namely the experimental group and the control group. The two-tier diagnostic test instrument was used to test the mental models of 134 students. The hypothesis was tested by ttest using the SPSS 16.0 program. The results of the ttest for each school were 0.011 at SMAN 3 Padang and 0.008 at SMAN 13 Padang, with a 0.05 significance level. The results of the t-test showed that the use of the module affected students' mental models.

This study aims to evaluate the implementation of cooperation between villages based on agrotourism in the Kendeng Mountains, Somagede District, Banyumas Regency as a model for developing rural areas in Banyumas Regency. The research was conducted in three villages in Somagede District, i.e., Tanggeran, Klinting, and Kemawi, and served as a pilot project for rural area development. Qualitative method is conducted through meetings with informants from all village officials and tourism business actors in the three collaborating villages and members of the Rural Area Development Coordination Team. This study employs qualitative method utilizing in-depth interviews, observations, documentation, and focus group discussion (FGD), while the findings were analyzed using an interactive analysis model. The results showed that the cooperation between the villages of Kemawi, Klinting, and Tanggeran in developing agrotourism-based rural areas did not yield the expected results. The failure is due to the absence of cooperation norms among members, the identification of common needs that must be resolved through inter-village collaboration, and the low commitment of the village heads to prioritize and carry out all program plans. The cooperation also fails because of the lack of support from the local government during program implementation and the absence of monitoring and evaluation activities at each stage of the implementation of inter-village cooperation.

The fabrication of a zinc hydroxide nitrate-sodium dodecylsulfate bispyribac modified with multi-walled carbon nanotube (ZHN-SDS-BP/MWCNT) paste electrode for uric acid and bisphenol A detection was presented in this study. Electrochemical impedance spectroscopy, chronocoulometry, square-wave voltammetry, and cyclic voltammetry were all used to examine the electrocatalytic activities of modified paste electrodes. The modified electrode’s sensitivity and selectivity have been considered in terms of the composition of the modifier in percentages, the types of supporting electrolytes used, the pH of the electrolyte, and square-wave voltammetry parameters like frequency, pulse size, and step increment. Square-wave voltammetry is performed by applying a small amplitude square-wave voltage to a scanning potential from −0.3 V to +1.0 V, demonstrating a quick response time and high sensitivity. The ZHN-SDS-BP/MWCNT sensor demonstrated a linear range for uric acid and bisphenol A from 5.0 µM to 0.7 mM, with a limit of detection of 0.4 µM and 0.8 µM, respectively, with good reproducibility, repeatability, and stability as well. The modified paste electrode was successfully used in the determination of uric acid and bisphenol A in samples of human urine and lake water.

Bakery product is a product with huge business opportunities in the domestic and international halal food market. Bakery companies are demanded to keep the trust of the consumers to the bakery product. The design of the halal assessment model is required to determine the critical point in the bakery-making business process. This assessment tool is intended to understand, know, and determine the critical point of the bakery production process from the halalness degree and is reviewed from all aspects such as the materials’ content, as well as the material acquisition and processing method based on 18 criteria of GMP principles (Good Manufacturing Practices). The halal assessment model designed in this research used QFD (Quality Function Deployment) approach which was integrated into the company’s business process and the halal critical bakery was grouped based on SCOR (Supply Chain Operations Reference) model. Matrix 1 integrated GMP (Good Manufacturing Practices) and business process (BP), matrix 2 integrated GMP (Good Manufacturing Practices), and halal critical bakery (HCB). The results of the design model implementation based on the standards set by the Halal Auditor of LPPOM MUI found that the standard matrix component 1 was met by the company by 47%, while the matrix component 2 was only able to meet the Auditor standards by 34% and the matrix component 3 standards were able to fulfilled by the company by 75%. The fulfillment value of each matrix is influenced by the negative gap that occurs, the negative gap occurs because of the standard criteria in the technical matrix that are not met. The result of this halal assessment model design is expected to help the company in evaluating and controlling critical points found in the business processes.

This research aims to describe the division of the roles of men and women in the ritual procession of the Perlon unggahan of the Blangkhon Islamic community, and to describe the meaning of the division of the roles of men and women in the ritual of the Perlon unggahan of the Blanghon Islamic community. This research uses a qualitative method. Data collection methods were carried out by means of in-depth inter- views, observation, documentation studies, and literature studies. The results of the study show that one of the main values in the ritual of the Perlon unggahan is respect for women, that women are representatives of God because humans are born in the world through female intermedi- aries. This main value shows the existence of gender equality in the ritual of the Perlon unggahan where male followers do not dominate and women are not considered subordinated, because there are unique roles that can- not be performed by men such as women being allowed to purify them- selves and come to Kyai Bonoheling’s grave first, in the past while the men were in charge of coohing. In addition, men and women are treated equally, namely walhing barefoot carrying produce of the earth from the Cilacap Regency area to Pehuncen Village, Banyumas Regency. Both men and women are given the freedom to follow the ritual according to their wishes, without any coercion and social sanctions.

Academic Entrepreneurship is an entrepreneurial activity conducted by scientists/academics who market their research results commercially to achieve specific economic benefits or rewards. This research focuses on academic entrepreneurship that occurs at Andalas University. There is still a lack of academics whose research products for commercialization are about 22.73%. It is because there are factors that influence academic entrepreneurship activities at Andalas University. One of them is the internal academic factor. The internal factors are Control System, Organizational Culture, Human Resource Management System, Organizational Structure, and Academic Leadership Behavior. The purpose of this study is to analyze the university's internal factors on academic entrepreneurship. This research uses a quantitative approach derived from 106 Andalas University academics with Structural Equation Modelling (SEM) methods with SmartPLS Software. The result obtained in this study is that the control system exerts a positive and negative influence on academic entrepreneurship. In contrast, other factors have a significant positive influence on academic entrepreneurship. The research results show that the university's control system, organizational structure, and human resources had no significant positive effect on academics at Andalas University. Meanwhile, entrepreneurial behavior and organizational culture have a significant positive effect on academic entrepreneurship at Andalas University. Further research should be analyzed for all universities with innovative products and are ready for commercialization throughout Indonesia. This research is still a case study and needs to be developed.

Inventory control is a very important issue. It is because the amount of inventory will determine or affect the smoothness of the production process as well as the effectiveness and efficiency of the company. PT Semen Padang is a manufacturing company that produces 10,400,000 tons of cement per year. The achievement of the cement production target at this company depends on the availability of raw materials needed in the cement production process itself. Gypsum is an additional material of the cement production process which is very important because it is a raw material that must exist in the process of making cement. So, if the inventory of gypsum cannot meet the needs of production, then the production process of cement making will be disrupted. PT Semen Padang is using the Min-Max method for inventory control. But the costs are quite high. The cost of inventory can be minimized by using another method such as EOQ (Economic Order Quantity). The conclusions of this research are in 2016 by using EOQ method, the optimal order quantity is 32,073 ton per order, and the frequency is 9 times in a year with total cost Rp. 4,757,673,813.48, and in 2017, the optimal order quantity is 34,856 tons per order and the frequency is 9 times in a year with total cost Rp. 9,694,805,608.36.

Ratio analysis is one of the most competent tools to predict the bankruptcy of a company. In this paper the bankruptcy prediction of listed cement company in Indonesian Stock Exchanges has been evaluated using Altman Z-score. This study aims to determine the level of the bankruptcy of the listed cement companies in the Indonesian Stock Exchange during 2013 to 2017. There are four listed cement companies, namely PT Semen A, PT Semen B, PT Semen C and PT Semen D. Based on the results of the research, it shows that PT Semen A, PT Semen B and PT Semen C are in the safe zone with the highest Z value which is 15,822 and the lowest Z value which is 3,542. PT Semen D is in the bankrupt zone because it has a Z value below 1.8. For that reason, all companies need to improve the performance immediately to avoid the bankruptcy happening. There are many ways to avoid the bankruptcy such as improving the sales revenue, improving operational cost and waste reduction in operation.

The composition of Napa soils (% w/w) used as variables include 4, 8, 12 and 16%. Furthermore, 8% pozzolan was used as a control in this research. The results showed that the compressive strength of Napa soil cement which contained 4% Napa soil was much better compared to that of the control on the 7th and 20th day. Furthermore, all the analyzed Napa soil cements met the standard of cement as stipulated in Indonesian National Standard, SNI 7064, 2016.

The awarding of investment grade to Indonesian Stock Exchange marked an excellent development in national capital market. This could be the key to attracting foreign investors that will further integrate the Indonesia capital market with international markets. Increasingly integrated capital market will also be more vulnerable to international issues such as the volatility of global stock indices as well as the volatility of world commodity prices (crude oil, CPO, gold etc.) as indicated by IHSG response to these issues. To minimize risk and maximize the return are the main goal of investment. Both of these two objectives can be achieved through stocks diversification and the portfolio development. Optimal portfolio require the right stocks diversification. Therefore, investor need to have information about which stocks are affected and unaffected by world commodity prices prior to diversify. The goal of this research is to examine way to form optimal portfolio from group of companies listed in Indonesian Stock Exchange and affected by world commodity prices. Augmented Dickey Fuller (ADF) method used for stationary test of time series data and residual regression models. Regression Analysis conducted for co-integration test between commodity prices and IHSG. Error Correction Model used for correcting short term errors. Optimal portfolio formed with Single Index Model and Treynor Index used to measure the optimal portfolio performance. Result of the study showed that gold, crude oil, platinum, rubber, corn, cotton, and Arabica coffee are the global commodities that can be used to predict the direction of IHSG movement.

A DNA micro-optode for dengue virus detection was developed based on the sandwich hybridization strategy of DNAs on succinimide-functionalized poly(n-butyl acrylate) (poly(nBA-NAS)) microspheres. Gold nanoparticles (AuNPs) with an average diameter of ~20 nm were synthesized using a centrifugation-based method and adsorbed on the submicrometer-sized polyelectrolyte-coated poly(styrene-co-acrylic acid) (PSA) latex particles via an electrostatic method. The AuNP−latex spheres were attached to the thiolated reporter probe (rDNA) by Au−thiol binding to functionalize as an optical gold−latex−rDNA label. The one-step sandwich hybridization recognition involved a pair of a DNA probe, i.e., capture probe (pDNA), and AuNP−PSA reporter label that flanked the target DNA (complementary DNA (cDNA)). The concentration of dengue virus cDNA was optically transduced by immobilized AuNP−PSA−rDNA conjugates as the DNA micro-optode exhibited a violet hue upon the DNA sandwich hybridization reaction, which could be monitored by a fiber-optic reflectance spectrophotometer at 637 nm. The optical genosensor showed a linear reflectance response over a wide cDNA concentration range from 1.0 × 10−21 M to 1.0 × 10−12 M cDNA (R2 = 0.9807) with a limit of detection (LOD) of 1 × 10−29 M. The DNA biosensor was reusable for three consecutive applications after regeneration with mild sodium hydroxide. The sandwich-type optical biosensor was well validated with a molecular reverse transcription polymerase chain reaction (RT-PCR) technique for screening of dengue virus in clinical samples, e.g., serum, urine, and saliva from dengue virus-infected patients under informed consent.

Though lecturing (speech) method is simpler for lecturer because simple class organization and he can control entire class direction, but its weakness is he difficult to know whether students have understood his discussion or not. Student’s learning effectiveness generally limited, only a critical moment near final test. One effort to support the improvement of learning quality is applying Student Centered Learning (SCL) approach. SCL is an activity that therein student work individually and also as group to exploring problems, searching knowledge actively rather than passive knowledge receiver. Learning method based on the SCL more appropriate to be applied at learning process in university, especially at Social Research Method course (MPS). Following John W. Best, “the best way to learn research is to do it,” so research method not only concerning cognitive domain, but also affective and psychomotor. Among learning technique based on SCL are jigsaw technique, hypothetical situation technique, and role-playing and simulation technique. .

ABSTRAK Tujuan penelitian ini adalah untuk mendeskripsikan dan menjawab pertanyaan penelitian: mengapa pola pengembangan ternak yang dilakukan oleh masyarakat suatu desa dapat berkembang ? bagaimana proses pola pengembangan usaha ternak yang dilakukan oleh masyarakat tersebut menjadi kebijakan Gerbang Anak Desa ? mengapa pelaksanaan Gerbang Anak Desa di desa tertentu masih dapat berjalan, sementara di desa lain sudah tidak berjalan lagi (tidak berhasil) ? bagaimana prospek Gerbang Anak Desa sekiranya dilaksanakan di desa-desa lainnya di seluruh kabupaten ? dan apakah Gerbang Anak Desa dapat dijadikan sebagai model alternatif pengentasan kemiskinan ? Penelitian ini menggunakan pendekatan kualitatif dengan bentuk studi kasus. Pengumpulan data dilakukan dengan menggunakan tehnik wawancara mendalam, observasi, dan dokumentasi. Lokasi penelitian dipilih Desa Sumingkir dan Limbangan kabupaten Dati II Purbalingga. Analisis data dilakukan dengan menggunakan analisis seperti yang dikembangkan oleh Strauss dan Corbin, yakni dengan melalui prosedur open coding, axial coding dan selective coding. Untuk menetapkan keabsahan data, digunakan tehnik pemeriksaan yang didasarkan atas kriteria derajat kepercayaan, keteralihan, kebergantungan, dan kepastian. Hasil penelitian menunjukkan pola pengembangan usaha ternak yang dirintis oleh masyarakat dapat berkembang karena didorong oleh motivasi individual dan keterbukaan masyarakat untuk menerima gagasan-gagasan baru yang datang dari luar. Keberhasilan penyebaran pola pengembangan ayam buras petelur di daerah lain, dipengaruhi oleh keberhasilan pengembangan pola tersebut pada masyarakat perintis. Proses perumusan kebijakan Gerbang Anak Desa bukan merupakan respon dari adanya permasalahan yang ada dalam masyarakat, namun lebih diwarnai oleh kepentingan pemerintah daerah, dan proses perumusannya yang didominasi oleh pemerintah daerah. Pelaksanaan "Gerbang Anak Desa" yang dapat berjalan dengan baik karena program tersebut berasal dan didukung oleh motivasi dari dalam masyarakat sendiri. Kegagalan implementasi Gerbang Anak Desa di daerah lain, disebabkan program tersebut berasal dan "dipaksakan" oleh aparat serta kurangnya motivasi dari dalam masyarakat sendiri. Prospek keberhasilan implementasi Gerbang Anak Desa yang sekaligus sebagai alternatif model pengentasan kemiskinan akan sulit terwujud karena tidak didukung oleh : sumberdaya keuangan, kesiapan aparat pelaksana, kepastian lokasi kawasan, kemampuan sumberdaya manusianya, kepastian keamanan lokasi kawasan, serta kecenderungan pelaksanaannya yang menggunakan pendekatan kekuasaan, lebih bersifat top down, dan tidak menciptakan kemandirian kelompok. Kata kunci: Gerbang anak desa, peternakan ABSTRACT The research dealing with the implementation of animal husbandry development policy is initiated from "the success" of livestock improvement pattern established by the people of Sumingkir Village, which is then developed and decided the Local Government Purbalingga as Gerbang Anak Desa policy, i.e the policy of animal husbandry development and the effort to improve breeders' prosperity in Purbalingga Regency. Before Gerbang Anak Desa policy was implemented in Purbalingga Regency entirely, it was implemented in two pilot villages. Such policy works and "survives" up to now in one ofthe pilot villages, while in another pilot village, it only worked for a year. Although the implementation of Gerbang Anak Desa in on of the pilot villages failed, it does not reduce the enthusiasm of the Local Government to insist on implementing the policy in all Purbalingga Regencies. With regards to "the success" and the failure of the policy implementation, it must be interesting to study : why is a livestock improvement pattern performed by the people of a village able to develop ? how does the process of livestock improvement pattern performed by such people become Gerbang Anak Desa policy ? why is the implementation of Gerbang Anak Desa in a certain village able to work, meanwhile in another village, it did not work anymore (failed) ? how is the prospect of Gerbang Anak Desa if it is implemented in other villages of the entire regencies ? and whether Gerbang Anak Desa may be used as alternative model of poverty alleviation. While the purpose of this research is to describe and to provide the answers to the research questions above. This research applied qualitative approach in the form of case study. The data collection was conducted with intensive interview technique, observation, and documentation. The location of research is Sumingkir and Limbangan Villages Purbalingga Regency. The data analysis was conducted by applying the analysis developed by Strauss and Corbin, namely by open coding, axial coding, and selective coding procedures. To determine the validity of the data, the examination technique was applied based on the criteria of credibility, transferability, dependability, and conformability. The result of the study indicated that the livestock improvement established by the people stated above may grow because of the support of individual motivation and people's openness to obtain external new ideas. The success in distributing domestic chicken improvement pattern to other areas is influenced by the success of such improvement pattern among pioneer people. The formulation process of Gerbang Anak Desa policy is not a respond of the problems existing among society, however it tends to be the interest of the local government, and its formulation process is dominated by local government. The implementation of Gerbang Anak Desa which runs well resulted from the fact that the program came from and supported by the motivation of the people themselves. The failure in implementing Gerbang Anak Desa in another area was caused by the fact that the program came from and "being forced" by the governmental agency, as well as the lack of motivation from the people themselves. The prospect of the success in implementing Gerbang Anak Desa and at the same time the passibility to make it as alternative model of poverty alleviation will be difficult to be realized, since it is not supported by: finacial resources, the readiness of human resources, the certainty of the location, the ability of the human resources, the security of the location ; as well as the tendency of the implementation which is more authority approach, top-down style, and does not create group autonomy.

An electrochemical microbiosensor for DNA has been fabricated based on new acrylic microspheres modified with reactive N-acryloxysuccinimide (NAS) functional groups. Hydrophobic poly(n-butylacrylate-N-acryloxysuccinimide) microspheres were synthesized in an emulsion form with a simple one-step photopolymerization technique. Aminated DNA probe was attached to the succinimde functional group of the acrylic microspheres via covalent bonding. The hybridization of the immobilized DNA probe with the complementary DNA was studied by differential pulse voltametry using anthraquninone-2-sulfonic acid monohydrate sodium salt (AQMS) as the electroactive hybridization label. The influences of many factors such as duration of DNA probe immobilization and hybridization, pH, type of ions, buffer concentrations, ionic strength, operational temperature and non-complementary DNA on the biosensor performance were evaluated. Under optimized conditions, the DNA microbiosensor demonstrated a linear response range to target DNA over a wide concentration range of 1.0 × 10−16 and 1.0 ´ 10−8 M with a lower limit of detection (LOD) of 9.46 ´ 10−17 M (R2 = 0.97). This DNA microbiosensor showed good reproducibility with 2.84% RSD (relative standard deviation) (n = 3). Application of the NAS-modified acrylic microspheres in the construction of DNA microbiosensor had improved the overall analytical performance of the resultant DNA microbiosensor when compared with other reported DNA biosensors using other nano-materials for membranes and microspheres as DNA immobilization matrices.

New acrylic microspheres were synthesised by photopolymerisation where the succinimide functional group was incorporated during the microsphere preparation. An optical biosensor for urea based on reflectance transduction with a large linear response range to urea was successfully developed using this material. The biosensor utilized succinimide-modified acrylic microspheres immobilized with a Nile blue chromoionophore (ETH 5294) for optical detection and urease enzyme was immobilized on the surface of the microspheres via the succinimide groups. No leaching of the enzyme or chromoionophore was observed. Hydrolysis of the urea by urease changes the pH and leads to a color change of the immobilized chromoionophore. When the color change was monitored by reflectance spectrophotometry, the linear response range of the biosensor to urea was from 0.01 to 1,000 mM (R2 = 0.97) with a limit of detection of 9.97 mM. The biosensor response showed good reproducibility (relative standard deviation = 1.43%, n = 5) with no interference by major cations such as Na+, K+, NH4+ and Mg2+. The use of reflectance as a transduction method led to a large linear response range that is better than that of many urea biosensors based on other optical transduction methods.

This paper attempt to assessing the impact of IT competency on organizational learning capability by using the measurement scale that have been developed by Tippins et al. and Gomes et al. These studies cover a sample of 192 manufacturing firms. IT competencies are classified into three dimensions: IT knowledge, IT operations, and IT objects, and organizational learning capability are classified into four dimensions: Managerial commitment, System perspec-tive, Openness and experimentation, and Knowledge transfer and integration. The result of factor analysis on IT competency and Organizational learning capability show that all items have high loading only on a single factor with ranging from .60 to .84. The findings revealed that IT competency positively and significantly influences the organizational learning capability of Indonesian manufacturing firms.

The rapid evolution of technology has reshaped the global economy, intensified competition, and prompted industry players to embrace innovation to maintain sustained competitiveness. In Indonesia, business incubators, overseen by universities and provincial/city governments, are pivotal. However, understanding the determinants of business incubator performance remains limited. This study investigates 24 statement items aiming to uncover the factors influencing technology business incubators in Indonesia, focusing on knowledge management as a mediating variable from a knowledge-based perspective. Employing a quantitative approach, structural equation modeling (SEM) is utilized to scrutinize these factors' impact on business incubator performance. The findings reveal that knowledge management serves as a full and partial mediator among funding support, government assistance, incubator governance, and business incubator technology performance. This research offers valuable insights for entrepreneurs and stakeholders by emphasizing the significance of funding, governmental backing, incubator governance, and knowledge management in enhancing incubator business technology performance in Indonesia.
