AbstractThis study investigated the effectiveness of botanical insecticides derived from leaf extracts of Azadirachta indica, Aglaia odorata, and Ageratum conyzoides against third instar larvae of Spodoptera litura through different application methods. The plant materials were mixed in a 1:1:1 ratio, extracted with 96% ethanol. The results showed that the botanical insecticides were effective in killing the S. litura larvae through both oral and topical application techniques. The topical application was more effective, with an average mortality rate of 98.75% compared to 82.5% for oral application. The LT50 values were 5.9991 and 3.8555 days for oral and topical treatments, respectively. The topical application was 35.73% faster in inducing mortality in S. litura compared to oral application. The larvae-treated with oral application had the highest total quinine-equivalent alkaloid content at 312.52 mg L−1, while the larvae-treated with topical application had the highest total flavonoid content at 3963.60 µg L−1 in the total flavonoid test. The highest value of total tannic acid-equivalent tannins was observed in larvae-treated with oral application at 1.76% w/v. All larvae that were treated, both orally and topically, in this study were found to contain terpenoids within their body. In conclusion, the botanical pesticides derived from the extracts of A. indica, A. odrata, and A. conyzoides have proven to be effective in controlling S. litura. The topical application technique has been found to be more efficient than oral application in inducing mortality. However, it is crucial to conduct further testing in both greenhouse and field conditions in the future.

The market share of Islamic commercial banks in Indonesia is small despite the fact that Indonesia is a predominantly Muslim country. This paper investigates the asymmetric effect of the deposit rate of conventional banks on Islamic bank deposits in Indonesia applying a dual banking system. This study employs the Non-linear ARDL (NARDL), using monthly data and covering 2009:M1–2019:M7. The findings clearly confirm the long-run relationship between the Islamic deposit and conventional deposit rate for any maturity. Furthermore, the impact of conventional bank deposit rate is asymmetry on Islamic bank deposit for any maturity, implying that Islamic bank deposits react differently to up and down in conventional bank deposit rates, but it tends to weaken for longer maturity. More interestingly, based on asymmetric results, Islamic bank deposits adjust at a higher speed to an increase in conventional deposit rates compared to a rise in the Islamic deposit rates. The results imply that Islamic bank depositors may transfer their funds to conventional bank deposits as conventional bank deposit rates rise in a dual banking environment known as displaced commercial risk (DCR).

Crocidolomia binotalis (Cb) (Zeller) is one of the main pests of cabbage which is difficult for farmers to control in the Ijen Crater in Indonesia. The demand for cabbage in Indonesia is increasing every year, so intensification efforts are continuously being made. Farmers intensively use synthetic pesticides as the primary control of Cb. The purpose of this study is to examine several control agents that can be used as an alternative to synthetic pesticides. Then, it provides recommendations to Ijen Crater farmers to adapt in reducing the use of synthetic pesticides. The biopesticide used was based on the Nuclear Polyhedrosis Virus strains of Spodoptera litura (SlNPV) and Helicoverpa armigera (HaNPV), botanical pesticides, and synthetic pesticides as a comparison treatment. SlNPv and HaNPV isolates were obtained from the Indonesian Sweetener and Fiber Crops Research Institute. The botanical pesticide formulas come from a combination of Azadiracta indica, Aglaia odorata, Ageratum conyzoides dried for one week and proposed to form flour. Then, it was extracted using 96% ethanol solvent, 0.5% tween 90 using a rotary evaporator at a temperature of 40oC. For synthetic pesticide, the treatment used the active ingredient Permethrin 20 mgL-1. The cb collected from the field was re-filtered in a Petri dish by providing artificial feed soaked with this material for 5 minutes. The highest mortality test results were found in the botanical pesticide formula with a value of 100% at 72 hours. Mortality in SlNPV and HaNPV tended to be stable with a maximum value of 72.02%. The results of mortality testing in the laboratory can be a recommendation for alternative control of Cb pests in cabbage plants in the field. In this case, it is an effort to reduce farmers' dependence on using synthetic pesticides.

The qualitative research was conducted in junior high school to know students’ conceptions and conceptual changes on temperature and heat, specifically on specific heat topics. This study uses the purposive sampling technique. The research was started by collecting data and observing the students. The next step was a try-out test instrument conducted in a regular eighth-grade class. The try-out test was used as an instrument test to the superior dan the regular class of seventh-grade and the superior class of eighth-grade. The research instrument was a conceptual test in essay form and then conducted an interview. The samples were the students who had many possibilities in answering the research instrument. Based on the result of the study, the students’ concepts can be divided into three types: scientific, alternative, and parallel. The conceptions of the excellent class of the seventh-grade, the regular class of seventh-grade, and the excellent class of eighth-grade are alternative concepts. The conceptual changes in the excellent eighth-grade class are decreasing students’ understanding of heat and temperature.

The issue of the South China Sea (SCS) dispute between the United States (U.S.) and China, which has not abated, has caused concern for countries in the region to escalate and lead to war from both sides. The thing that becomes the biggest threat when there is a nuclear war between the U.S. and China where will have an impact on several countries, one of them is Indonesia. This study tries to provide an overview of how to determine Indonesia's strategic policy from the hypothesis of existing policy options based on possible scenarios by formulating a strategic thinking framework to prevent the use of nuclear weapons as a result of the U.S.-China dispute in the SCS, using Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP) methods to determine the right policy strategy. The results of AHP and ANP methods show the same results, where ASEAN-SEANWFZ (The Association of Southeast Asian Nations-Southeast Asia Nuclear Weapons Free Zone) Multilateral Diplomacy is the Policy Choice that gets the biggest priority, and Peaceful Solutions become the Scenario that gets the highest priority.

Inorganic glass waste can replace sand in mortar production due to its SiO2 content being greater than 70%. This study aims to analyze the increase in mortal product agility due to the substitution of sand and reducing environmental pollution. The fine glass waste used is restrained on 80 and 120 mesh sieves. The fine glass waste substitution variations are 0, 10, 20, 30, 40, and 50% of the sand weight. The results show that fine glass waste could be used as a material for sand substitution because of the content of SiO2 of 73.8%. The results from XRD indicate that the phase of fine waste glass is amorphous. The mortar was printed with a 5x5x5 cm cube mold, and it was soaked for 7, 14, and 21 days. Based on the results, the compressive strength with a high value of 13.58 MPa at 20% fine glass waste substitution and 120 mesh. The density of 2.8±0.8 g/cm3, porosity 4.40±0.001%, and absorption 2.83±0,0009%. The compressive strengths, density, porosity, absorption, XRF and XRD characterization were evaluated. The results showed that the SiO2 compound in waste glass with the right composition of 20% could significantly increase the compressive strength. Phase formation of Calcite (CaCO3), Quartz (SiO2), and Portlandite (Ca(OH)2) was formed from the results of XRF characterization

This study explores the influence of funding liquidity risk and several control variables on Islamic rural banks’ asset risk in Indonesia. Our study analyzes Islamic rural banks comprising 142 Islamic banks with quarterly data from 2013: Q1 to 2018: Q4. Panel regression is then employed. We divide Islamic banks related to their size and location for further analysis. Our results confirm the funding liquidity risk increase Islamic banks’ asset risk. Small Islamic banks encounter less asset risk than large Islamic banks, but large banks face a lower probability of bad financing than small Islamic banks. The influence of funding liquidity risk on asset risk is higher for Islamic banks in developed areas than in less developed areas. More interestingly, the results using an interaction term between funding liquidity risk and financial contracts show that Islamic banks providing profit-loss sharing contracts (PLS) and non-PLS face lower asset risk than those Islamic banks providing only non-PLS contracts. Results also highlight the importance of market power, size, financing, and efficiency in lowering asset risk. Our findings have two implications. First, policymakers can implement investment account product to reduce mismatch between liquidity risk and asset risk. Second, Islamic banks should provide both PLS and non-PLS contracts by optimizing both contracts to reduce Islamic banks’ risk assets.

Keberhasilan suatu proyek dapat diukur dari dua hal, yaitu keuntungan yang didapat serta ketepatan waktu penyelesaian. Dalam pelaksanaan pada proyek preservasi jalan ruas gunung kemala-sanggi ada indikasi mengalami keterlambatan dimana pada kontrak 01 ada sisa pekerjaan yang belum selesai mengakibatkan adanya kontrak 02, sehingga perlu dilakukan percepatan. Hal ini dimaksudkan agar proyek ini dapat terselesaikan lebih cepat sesuai dengan target rencana. Metode percepatan yang digunakan yaitu Time Cost Trade Off, dengan alternatif penambahan jam kerja lembur selama 1 jam. Metodologi penelitian ini memliki beberapa tahapan diantaranya pengumpulan data primer seperti data preservasi jalan dan data lokasi, serta data sekunder seperti tinjauan pustaka, data rencana anggaran biaya (rab), data time schedule proyek, data laporan bulanan. Dari hasil alternatif penambahan jam kerja lembur pada proyek preservasi jalan ruas gunung kemala-sanggi didapatkan durasi percepatan 89 hari dari durasi sebelumya 112 hari lebih cepat 23 hari sehingga pelaksanaan pekerjaan dapat sesuai dengan rencana awal penjadwalan yang didapatkan dari kurva S proyek. Pengurangan biaya total akhir proyek akibat percepatan sebesar Rp 687.273.911 sehingga biaya total proyek menjadi Rp 21.567.130.687. dari nilai total sebelumnya Rp 22.186.544.124. Diharapkan untuk penelitian selanjutnya dapat mengembangkan penelitian tentang analisa time cost trade off, misalnya dengan mengembangkan analisa dengan menghitung upah lembur tenaga kerja, biaya operasional alat saat digunakan untuk lembur atau menambahkan jumlah alat.

One of the biggest issues impeding a country’s progress is the lack of power. To overcome this issue, hybrid renewable energy systems (HRES) play an important role. Due to rising consumption and diminishing resources globally, sustainability has recently attracted more attention. Bangladesh has access to renewable energy sources, including solar, micro-hydro, biomass, wind, and others. The objective of this research is to minimize the net present cost (NPC), cost of energy (COE), and CO2 emissions of the suggested electricity network using the Hybrid Optimization Model for Multiple Energy Resources (HOMER) Pro Software. This investigation explores the possible use of a hybridized energy system (i.e., solar, wind, and diesel) with battery storage in Bangladesh’s northern area. Utilizing HOMER Pro software, an optimal grid-connected system is chosen after evaluating the techno-economic viability of several configuration options. For the Rangpur metropolitan region, seven distinct grid-connected solutions with stationary renewable sources are simulated. The HRES is designed to meet demands for hospital, diagnostic, school, and operation theatre loads of 3250.00 kWh, 250.00 kW maximum requirement, and 570.00 kWh, 71.25 kW maximum electricity demand, respectively. Multivariate linear regression (MLR) is used to assess the suggested optimal combination in terms of system size, cost, technical performance, and environmental stability. The findings show that the metric real-time rate (annual) has emerged as the most advantageous option since economic criteria like total NPC and COE are preferred above others.

Kayumas Village was a unique village to study. The uniqueness could be traced through an evidence on 19 April 1883 when the Dutch investor HHvan Kol and his colleague JCEgter van Wissekerke were interested in leasing 504 bau of vacant land in Kajoemaas plateau to the Dutch colonial government for 75 years to establish the company "Cultuur Maatschappij Kajoemaas", whereas the location of Kajoemaas region was isolated and difficult to reach. The land was apparently planted with Arabica coffee because of the geographical location of the area was more than 760-1550 meters above sea level, and succeeded in producing Arabica Coffee exported to Europe. When Indonesia gained its independence, the company was nationalized and changed its position by PT. Perkebunan Nusantara XII (PTPN XII) by changing the name to be "Kayumas Arabica Coffee Processing". This Arabica coffee processing factory later inspired the farmers of Kayumas Village to cultivate their lands. This study was dissected using a political economy theory as combined with the historical method. The theory of Political Economy was used to trace the emergence of the critical thinking of Kayumas Village farmers to grow and crop Arabica coffee as the same as the PTPN XII. Meanwhile, the historical method was used to track the strategies used by farmers to survive. This study has resulted and proven that the majority of farmers in Kayumas Village chose to plant Arabica coffee as a strategy to survive along with PTPN XII. It was also proven that the coffee farmers in Kayumas village were more prosperous than farmers in other villages.

This study set out to establish if creative writing ability, the quality of language learning, exercise intensity, and methodological mastery had any effect, either individually or simultaneously, on the quality of journal articles written by undergraduate students at the State Islamic University of Purwokerto. This study was quantitative in nature and applied a correlational technique. The study's participants were all undergraduate students who had published at least one paper in a scientific journal. Based on the faculties and study programs, proportionate random sampling was used to select a sample of 185 students. Questionnaires were distributed to this sample to collect primary data. With the help of the SPSS version 25.0 application, the data were analyzed using one-predictor regression analysis and multivariate regression. The study found out that learning the Indonesian language not only serves a function as the official state language and a tool for developing culture, science, and technology--it also serves as a learning tool that contributes to efforts to improve the quality of education and student journal articles. Of the four variables analyzed, the variable that contributes most is the quality of language learning, followed by the intensity of exercise. The variable with the smallest contribution was creative writing ability. Based on this, it could be concluded that creative writing ability, the quality of language learning, intensity of practice, and methodological mastery significantly influence the quality of journal articles by undergraduate students at the State Islamic University of Purwokerto, both individually and in combination.

The center of mass (CM) is an abstract quantity but essential as a reference point used to understand the position and movement of an object or a system of objects. Many researchers have used video recordings to analyze and understand the movement of objects in a system. In a system with colliding objects, the motion can be obtained precisely from video analysis. Estimating the momentum of each object can allow analysis of the conservation of linear momentum of the collision.
