Instruments of research that we used are the rubric of the teaching-learning process, the rubric of student activity, and the rubric of the cooperative learning model. From the data analysis, the learning model used in this online class meeting is proper enough for it is fulfilled the syntax of cooperative learning. So Cooperative learning models can be a good way to teach much content at a time effectively. However, managing students to be more active is needed in the learning process.

The degreening of “Selayar” orange using ethephon: The color peel changes and ethephon residue

The degreening technology using etilen to improve the colour of “Selayar” orange peel is impracticable to apply because this exists the gases form, so it can be substituted with working use Ethephon. Ethephon is more practical to use because this is a liquid. However, its use requirement prioritizes the principle of caution because it leaves residual. This study aimed to analyze the colour changes of the orange peel and Ethephon residues in degreening applications. This study used a completely randomized design with three concentration treatments, namely 0 ppm, 500 ppm, and 1000 ppm, with four repetitions. This research showed that the Ethephon in concentration 500 ppm was not significantly different from the 1000 ppm ethaphon treatment on fruit peels colour based on L *, a *, b *, colour index (CCI), and hue (h). Both concentrations exist to develop the orange peel colour, while the control fruits (0 ppm) are solely green on the 7th day of observation and greenish-yellow on the 14th day. Ethephon residue on orange fruit peels for 1000 ppm treatment approximately 0.30 ppm while at the group of 500 ppm ended 0.03 ppm. Degreening with ethaphon concentrations of 500 ppm and 1000 ppm has the identical ability to improve the peel colour of “Selayar” orange. The ethaphon residue in both concentrations (500 and 1000 ppm) is more moderate than the maximum admitted by the Indonesian government and Codex, namely 0.05 ppm.

Hydraulic analysis of Semarang River in supporting the drainage channel as water tourism

The Semarang River is a flushing channel located in the Semarang River Drainage Sub-System and has the potential to be used as a water tourism area with the concept of Historical River Front City Walk. The planned water tourism area is in the form of procuring boats in the Kota Lama area, which is a historic area in the city of Semarang. This analysis aims to hydrology and hydraulics model of the Semarang River using SWMM 5.1. The method is carried out by observing the existing conditions of the study area, determination of flood discharge plans, and hydraulic analysis. The analysis starts from the Simongan Weir Bridge upstream of the Semarang River to the Berok 2 Bridge, which is located in the Kota Lama area. The results showed the intensity of rainfall designed 25 years is 155.7 mm/hour with the capacity of the Semarang River in existing and planning conditions can still accommodate the flood discharge plan, and a weir with a height of 1 m is needed to maintain the water level in boundary condition so that boat tours can operate optimally.

Potential Role of Cutting Date in Lodging and Yield of Three Oat Cultivars

This study aimed to investigate the role of cutting at different growth stages according to the Zadoks scale and the possibility of reducing plant height and lodging at the end of the season. Moreover, it aimed to study the effect of cutting on some growth and yield traits of oat cultivars introduced into Iraq. A field experiment was carried out in an agricultural area on the left bank of the Euphrates River in the city of Ramadi during the winter season of 2020-2021. In this experiment, a randomized complete block design (RCBD), factorial arrangement, with three replications was used. The experiment included two factors: the first factor included three cutting dates according to the Zadoks scale: “Main stem and one tiller (GS21), main stem and four tillers (GS24), Main stem and seven tillers (GS27)”, in addition to the control without cutting. The second factor included three oat cultivars: Carrolup, Genzania, and Shafa. The most important results are summarized as follows: Cutting at all growth stages delayed ripening and reduced plant height, cutting at GS24 and GS27 reduced lodging, and cutting at GS27 reduced the grains per panicle, 1000 grain weight, grain yield, and total dry matter. Genzania cultivar was superior in grain yield and total dry matter. The cultivars showed similar responses to cutting dates in the terms of lodging and yield. It can be concluded from this study that cutting at GS24 is beneficial in reducing lodging without a negative impact on yield quantity.

Evaluation of Retinal Structure and Optic Nerve Function Changes in Multiple Sclerosis: Longitudinal Study with 1-Year Follow-Up

Background Multiple sclerosis (MS) is an autoimmune disease characterized by inflammation and demyelination of the central nervous system which often involves the optic nerve even though only 20% of the patients experience optic neuritis (ON).Objective This study aims to compare the retinal structure and optic nerve function between patients with MS and healthy controls (HCs), evaluate optic nerve alterations in MS over 1-year follow-up, and analyze its correlations with disease duration, number of relapses, degree of disability, and different subtypes.Methods This is a prospective cohort study involving 58 eyes of MS patients. Optic nerve function was evaluated with best-corrected visual acuity (BCVA), contrast sensitivity, and P100 latency, while the retinal structure was evaluated from the GCIPL and RNFL thickness measured with optical coherence tomography (OCT) and fundus photography.Results The MS group had lower BCVA ( p =0.001), contrast sensitivity ( p < 0.001), mean GCIPL thickness ( p < 0.001), and mean RNFL thickness ( p < 0.001) than HC. At 6 and 12 months of observations, GCIPL and RNFL (nasal quadrant) of MS patients decreased significantly ( p =0.007 and p =0.004, respectively). Disease duration and the number of relapses correlated with delayed P100 latency ( r  = −0.61, p < 0.001 and r  = −0.46, p =0.02). GCIPL and RNFL in the SPMS subtype were thinner than in RRMS.Conclusions The retinal structure and optic nerve function of MS patients are worse than those of normal individuals. GCIPL and RNFL thinning occurs at 6 and 12 months but do not correlate with disease duration, the number of relapses, and degree of disability.

Integrated Land Registration System: Between Legal Certainty and Challenges (Case of Semarang City)

In providing legal certainty for the control and ownership of community land parcels, the government carries out a program of registration and data collection of land parcels or what is called Complete Systematic Land Registration (PTSL). In its implementation, the city government of Semarang is targeting as many as 50,000 certificates to be registered with a total of 55,000 land parcels so that with a high quantity output, many problems will occur and a strategy is needed to solve it. Based on these problems, it is necessary to study related problems and the completion of the Semarang City PTSL Program 2021. The research was carried out using a juridical approach by obtaining the results of research in the field. Especially in the area of Bendan Duwur and Sampangan urban villages, Semarang City in implementing the PTSL program in 2021 in the City of Semarang. Through this research, the obstacles to implementing PTSL Semarang City 2021 lie in the implementation of socialization, data collection and asset registration as well as in digitizing PTSL data. The settlement strategy that can be taken to minimize the problems of implementing PTSL is by improving resource strategies, coordinating with villages / sub-districts in making a Physical Land Acquisition Statement, as well as educating the public regarding online data that has been undertaken to support conversion from analog data to data. digital.
