Published: August 2022

The primary need for cooking oil or edible oil, the demand for cooking oil raw materials increases from year to year, this increase forces producers of crude palm oil (CPO) to compete to produce quality CPO products. PT. Sinar Pandawa, which is located in the Sennah plantation village, Batang downstream district, Labuhan Batu district, is one of the companies that produce CPO. Therefore, this study aims to determine the quality of CPO PT. Sinar Pandawa has good quality by using an analysis process of free fatty acid levels, namely the amount of free fatty acids resulting from hydrolysis and fat oxidation reactions, water content, namely the amount of water content in CPO and levels of impurities are foreign substances that do not dissolve. The method used in this research is titration using 0.1 NaOH solution for analysis of free fatty acid levels. The oven is open for moisture analysis i.e. heating the sample until the remaining water evaporates. Gravimetry for analysis of impurities content by filtering the sample using Whatman filter paper. The results show that the quality of CPO at PT. Sinar Pandawa which has the highest levels of fatty acids at 5.08%, water content of 0.35% and dirt content of 0.034%. The results of the analysis that has been carried out stated that the quality of CPO PT. Sinar Pandawa has not met the quality standards of SNI. The high value of each parameter, namely free fatty acid content, water content and dirt content with test values in accordance with SNI-2901-2006 maximum free fatty acid content of 5%, 0.25% water content and 0.25% dirt content indicates a lack of quality.

Published: August 2022

Papaya (Carica papaya L.) is one of the most popular fruits in the community and is generally only used as an ingredient for consumption in a fresh state. Papaya fruit production tends to be dynamic where sometimes the abundant amount of fruit may not necessarily be marketed directly. This causes the stock of papaya fruit during storage to rot and cannot be reused. This study aims to explore the potential of ripe papaya fruit to be processed as a substrate for the manufacture of liquid fertilizer using local microorganisms or effective microorganisms (EM). The quality of EM-based liquid fertilizer was determined based on the bacterial population density (CFU/mL) using the standard plate count (SPC) method on different growth media, then the levels of IAA and NPK in the applied fermented papaya fruit. The results showed the occurrence of nitrogen fixing bacteria, phosphate solubilizing bacteria and chitinolytic bacteria besides the cosmopolite bacteria. The optimum level of IAA in the fermented papaya fruit was EM + molasses (100%) while the NPK profile was still higher in the EM treatment without molasses.

PROSPECTIVE INDONESIAN EFL TEACHERS’ PROBLEMS IN PLACING VERB STRESS
Authors: Yulia Made Frida , Utami Lucia Niken Tyas
Published: August 2022

In creating successful communication, pronunciation is one aspect which should be mastered well by EFL learners, particularly by prospective teachers who will later become role models for their students. One of the essential pronunciation features is stress. Although sometimes neglected, stress is said to have necessary implication for one’s speaking skills. This study attempted to reveal the problems in verb stress placement encountered by prospective Indonesian EFL teachers. The data were obtained from the recording of their class presentations. The verbs uttered during the presentations were categorized into verb types depending on the number of syllables, i.e. disyllabic verbs, trisyllabic verbs, and tetrasyllabic (or longer) verbs, and then analyzed in terms of their pronunciation accuracy. From the analysis, it could be concluded that there were two kinds of problems in placing verb stress which the prospective Indonesian EFL teachers encountered, namely they misplaced the stress and they put double stresses on a verb. Most of them put the stress on syllables which could not obtain any stresses, such as suffixes. Meanwhile, some others put double stresses on either trisyllabic verbs or verbs with four or more syllables, where, in fact, such stresses could only be obtained by disyllabic verbs.

Published: August 2022

The study sought to investigate the physico-chemical properties of the Muni Lagoon and its catchment in Winneba, Ghana. This was an onsite study, thus all the data were taken in situ. Parameters which allow for on-field measurements were measured and used in conducting this study. Field observations, field measurements, and recordings of physical parameters in situ were the data collection methods. Data was analyzed using descriptive statistics and presented on bar graphs. The field results were compared to the standards set by the World Health Organization (WHO) and the United States Environmental Protection Agency (USEPA). The field measurements indicated that all the parameters tested within the Muni catchment were within the thresholds provided by the WHO and USEPA. Though parameters were within the acceptable threshold, field observations over the years revealed that there had been a great decline in biodiversity within the catchment, which could be attributed to anthropogenic activities such as encroachment, overfishing, harvesting of mangroves and waste intrusion. It is recommended that there should be constant monthly water quality monitoring of the water bodies within the Muni catchment to inform their status from time to time. The Forestry and Wildlife Commission of the Effutu Municipality should conduct routine community outreach programs on the radio to sensitize people on the effects of their actions on the catchment.

Published: August 2022

Object tracking is an area of study of great interest to various researchers, where the main objective is to improve estimation of the trajectory of a moving object. This is due to the fact that in the object tracking process there are usually variations between the true position of the moving object and the estimated position, that is, the object is not exactly followed throughout its trajectory. These variations can be thought of as Colored Measurement Noise (CMN) caused by the object and the movement of the camera frame. In this paper, we treat such differences as Gauss-Markov colored measurement noise.We use Finite Impulse Response and Kalman Filters with a recursive strategy on the tracking: predict and update. To demonstrate the filter with the best performance, tests were carried out with simulated trajectories and with benchmarks from a database available online. The UFIR modified for CMN algorithm showed favorable results with high precision and accuracy in the object tracking process with benchamark data and under no ideal conditions.While KF CMN showed better results in tests with simulated data under ideal conditions.

Published: August 2022

Conditions during the COVID-19 pandemic are continuously requiring teachers to improve their use of innovative behavior at work. Several previous studies have proven that learning orientation culture has an influence on innovative behavior. However, all of these studies have been conducted in the industrial sector. The current study aims to examine the relationship between learning orientation culture and teacher’s innovative behavior. Respondents of the study included 36 teachers from six cities in Java, Indonesia: Surabaya, Malang, Semarang, Salatiga, Surakarta and Yogyakarta. The results show that there was no relationship between learning orientation culture and teacher’s innovative behavior. Meanwhile, in the current study, only the intra-organizational knowledge sharing component had a significant correlation with teacher’s innovative behavior. Different job characteristics for teachers and employees in the industrial sector are the main point of argument in the discussion of this research.

Published: August 2022

This work reports on the extraction and characterization of carbohydrates such as cellulose, cellulose nanofibres, hemicellulose, and lignin from agricultural waste, i.e. maize stalks and sugarcane bagasse. The chemical compounds were extracted by hot water extraction (HWE) followed by alkaline extraction with 10 wt.% of sodium hydroxide (NaOH). Cellulose nanofibres (CNF) were isolated by mechanical grinding the cellulose fraction using a supermass colloider. The characteristics of the different fractionated components were investigated using nuclear magnetic resonance (NMR) spectroscopy, elemental analysis, thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectroscopy and X-Ray diffraction (XRD). The removal of the hemicellulose, lignin and extractives were confirmed quantitatively by TAPPI standard methods. It was observed that the cellulose content and its crystallinity increased after treating maize stalks and sugarcane bagasse with hot water extraction and alkali treatment. The thermal stability of cellulose also improved after treatments.  Transmission Electron Microscopy (TEM) results confirmed that web-shaped CNF were successfully extracted from the cellulose obtained from sugarcane bagasse and maize stalks. The dimensions of the CNF ranged from 5 to 30 nm in width and a few microns in length. In future studies, the fractionated hemicellulose, lignin and (micro and nano) cellulose will be used as reinforcements in the development of biocomposite materials.

Published: August 2022

Most accidents of centrifugal compressors are caused by fluid pulsation or unsteady fluid excitation. Rotating stall, as an unstable flow phenomenon in the compressor, is a difficult point in the field of fluid machinery research. In this paper, A stack denoising kernel autoencoder neural network method is proposed to study the early warning of rotating stall in a centrifugal compressor. By collecting the pressure pulsation signals of the centrifugal compressor under different flow rates in engineering practice, a double hidden layer sparse denoising autoencoder neural network is constructed. According to the output labels of the network, it can be judged whether the rotation stall occurs. At the same time, the Gaussian kernel is used to optimize the loss function of the whole neural network to improve the signal feature learning ability of the network. From the experimental results, it can be seen that the flow state of the centrifugal compressor is accurately judged, and the rotation stall early warning of the centrifugal compressor at different speeds is realized, which lays a foundation for the research of intelligent operation and maintenance of the centrifugal compressor.

Tradisi Tarian Mangaru merupakan salah satu tarian kesenian pemerintahan pada masa kesultanan Buton yang menggambarkan patriotism, nasionalisme dan solidaritas antar kerajaan ataupun kesultanan. Perbagai penelitian telah dilakukan untuk mengkaji tradisi Tari Menagaru agar kesenian ini tetap lestari adanya, namun penelitian terdahulu terbatas pada  sejarah dan perkembangan Tari Mangaru itu sendiri sehingga perlu penelitian lebih lanjut untuk memperkaya khazanah budaya kaitannya dengan keilmuan lainnya.  Adapun tujuan dari penelitian ini adalah untuk mengetahui nilai-nilai pedidikan anak usia dini pada implementasi tradisi Tari Mangaru di Kepulauan Buton khususya di Wakalambe. Penelitian ini menggunakan pendekatan kualitatif dengan analisis deskriptif melalui observasi, wawancara dan dokumentasi pada beberapa informan dan tokoh masyarakat. Hasil penelitian ini menggambarkan bahwa implemetasi tradisi Tarian mangaru memiliki nilai-nilai pendidikan untuk anak usia dini seperti menanamkan anak akan kecintaan budaya, memiliki etika, stimulasi perkembangan motoric, perkembangan kognitif anak, perkembangan bahasa, perkembangan sosial emosional dan perkembangan seni anak. Nilai-nilai pendidikan pada tradisi Tari Mangaru ini terakumulasi secara utuh dalam pertunjukan Tarian Mangaru. Dengan demikian Tarian Mangaru dapat dilestarikan dengan menstimulasi anak  untuk belajar tarian Mangaru sejak dini utamanya  usia Taman Kanak-Kanak.
Romanların İktisadi Yetkinliği: Ahmet Hamdi Tanpınar’ın Huzur Adlı Romanını Sabri Ülgener’in Fikirleri Üzerinden Okumak

Pozitif bilimle uğraşan insanlar, edebiyatçıları genelde hayalperest ve gerçekdışı olmakla yargılarlar. Edebiyatçılar ise pozitivist bilim adamlarını, ruhlarından arınmış, materyalizm sığlığında boğulmuş bir güruh olarak kabul ederler. Her iki bakış açısının, doğru kabul edileceği noktalar olmakla birlikte, bu farklı iki dünyanın insanlarının ittifak edecekleri noktaların bulunabileceği ihtimal dâhilindedir. Sonuç olarak amaç, hayatın sırlarını açığa çıkarmak ise sınırları olan bu hayatın bir noktasında buluşacaklardır. Özellikle iktisat gibi bir sosyal bilim ile edebi bir eserin kesiştiği alanları keşfetmek, bu iki farklı bakış açısının, aynı mevzu üzerinde alternatif olmaktan ziyade tamamlayıcı bir tavır takınacağı mantıktan uzak değildir. Bir taraftan maddeyi tarif ederken diğer taraftan manayı anlamaya çalışmak bir bütünlük oluşturacaktır. Bu bütünlüklü çalışma problemlerin anlaşılmasında ve çözümünde rehberlik edecektir. Bu çalışma, bu noktada bir rehber olmak iddiasında olmaktan ziyade bir ilham oluşturma gayesiyle ele alınmıştır. Bir iktisatçı olan Sabri Ülgener’in fikirleri üzerinden Ahmet Hamdi Tanpınar’ın Huzur isimli romanında, iktisadi keşifler yapılarak Türk toplumunun kronik ekonomik sorunları çözümlenmeye çalışılacaktır

Authors: PIÇAK Şeyma
Published: August 2022

Meclis aracılığıyla bütçe hakkını elinde bulunduran halk, kamu ekonomisini bu yolla denetlemiş olur. Bütçe oluşturulurken yapılan tahminler gerçekleşen rakamlara ne kadar yakın olursa halkın yönetenlere ve ekonomiye olan güveni o kadar artacaktır. Böyle önemli bir konuda birçok araştırma yapılmış ve yapılmaya devam edecektir. Bu çalışmada 1990-2020 yılları bütçe tahminlerinin sapmaları objektif doğruluk ilkesi kapsamında incelenmiştir. Tahmin sapmalarının yorumlanması için ilk olarak tahmin hatası daha sonrasında Theil’in eşitsizlik katsayısı yöntemleri kullanılmıştır. 1990-2020 yılları hem toplam olarak hem de bir kırılma yaşanabileceği düşüncesiyle Orta Vadeli Mali Planın uygulanmaya başlandığı yıl olan 2006’dan itibaren bölünerek iki dönem şeklinde incelenmiştir. Sonuç olarak bütçe giderlerinin zamanla daha doğru tahmin edildiği ancak bütçe gelirlerinin tahmin hatalarında iyileşmenin olmadığı görülmüştür.
