Abstract: The purpose of this study is making comparison between calculation of the potential for energy savings without and with taking into account the interdependency effect based on a case study in a conditioned high rise office building in Jakarta. Accurate estimation of the energy saving potential will increase the confidence level in bankable investment of energy saving projects. This will minimize the uncertainty of achievable energy savings which can prevent investment risks during implementing energy conservation and efficiency projects. The results of this study based on a study case, indicate that estimated energy savings of ESM-1 e.g. retrofit of lighting increase 4.29% when the interdependency effect is taking into account. ESM-2 e.g. installation of variable speed drive (VSD) on the air handling unit (AHU) shows the estimated energy saving increase 22.75% by taking into account interdependency effect. The effect of this interdependence both ESM-1 and ESM-2 is a reduction in cooling load in buildings. Totally, the calculation of the interdependency effect will increase the percentage of the total estimate of potential energy savings from 34.23% to 39.05% based on the energy baseline with a predefined baseyear periode, around 4.82% increased. The calculation of the interdependency effect will be very influential in minimizing uncertainty when the projects are financed by an energy performance contract mechanism whether a guaranteed or shared saving scheme. The measurement and verification energy saving during reporting period should be conducted in the future to compare the energy saving projection before ESMs implementation and measurement and verification results.

Ikan tongkol (Euthynnus affinis) merupakan salah satu komoditas penting yang banyak didaratkan di Pangkalan Pendaratan Ikan (PPI) Tanjung Luar. Kebutuhan akan ikan tongkol di pasaran yang relatif tinggi dengan harga ekonomis menyebabkan tingginya intensitas penangkapan ikan oleh nelayan tanpa memperhatikan musim tangkap dan karakteristik layak tangkap, sehingga tidak sedikit ikan tongkol yang tertangkap pada saat matang gonad bahkan yang sedang melakukan pemijahan. Tujuan penelitian ini adalah untuk mendeskripsikan aspek-aspek reproduksi ikan tongkol yang terdiri dari tingkat kematangan gonad (TKG), indeks kematangan gonad (IKG) dan fekunditas. Penelitian ini dilaksanakan pada bulan Mei sampai Juni 2018. Total sampel yang diamati sebanyak 120 ekor ikan tongkol betina yang dikumpulkan dari PPI Tanjung Luar. Teknik penentuan sampel yang digunakan dalam penelitian ini adalah teknik sampel kuota. Pengamatan TKG dilakukan dengan cara pengamatan morfologis berdasarkan skala kematangan gonad, kemudian menghitung TKG atau Gonado Somatic Index (GSI). Perhitungan fekunditas yang dilakukan pada ikan tongkol sejumlah 36 sampel pada TKG V dan VI menggunakan metode gravimetrik. Kesimpulan penelitian ini menunjukkan bahwa TKG ikan tongkol betina didominasi oleh TKG IV sebanyak 51,67%, kemudian diikuti TKG V (36,67%), TKG III (23,33%), TKG VI (8,33%) TKG II (8,33%) dan TKG I (6,62%). Dari persentase TKG tersebut menunjukkan bahwa ikan tongkol belum matang gonad (TKG IV). Nilai Gonado Somatic Index ikan tongkol betina berkisar antara 0,0116%-0,0258%. Fekunditas ikan tongkol betina berkisar antara 192.246-601.497 butir telur pada kisaran panjang cagak 415-640 mm.
金枪鱼(Euthynnus affinis)是一种重要的商品，在好望角的鱼港(PPI)登陆。在价格相对较高的市场上，由于渔业在不考虑渔获季节和有价值的特征的情况下所捕捞的渔获量高，因此在鱼群成熟时甚至在产卵时所捕获的金枪鱼并不多。该研究的目的是描述雄鲭鱼生殖的各个方面，它包括长尾鱼的成熟度(TKG)、长尾鱼(IKG)和凤尾鱼的成熟度。这项研究将于2018年5月至6月进行。从好望角PPI采集的观察到的总样本多达120只雌性雄天鹅。本研究采用的样本确定技术为配额样本技术。TKG观测是根据槽的成熟度进行的，然后计算TKG或体形股指数(GSI)。根据TKG V和VI的36个样例，用重力测量法对鲭鱼进行了温床计算。这项研究的结论表明，TKG雌鲭鱼的主导范围是51.67%，然后是TKG V (36,67%)， TKG III (3.3.33%)， TKG VI (8.33%) TKG II(8.33%)和TKG I(6.62%)。TKG的这一比例表明，公鲭鱼还没有完全成熟的躯干鱼(TKG IV)。雌性雄鱼的育肥范围从192246 - 601,497个卵到415-640毫米。

In the event of distance learning (PJJ), during the pandemic, teachers are required to be able to compile an appropriate learning syllabus. An educational syllabus based on culture and national character is needed to help the learning process professionally during PJJ. The role of the principal in conducting academic supervision to improve competence in compiling a syllabus for cultural education and national character is a necessity. Based on the problems faced by SMPN 21 Semarang teachers, namely the low competence in compiling a syllabus that is integrated with cultural education and national character during PJJ, it is necessary to find a solution. To overcome the problems mentioned above, school principals need to take actions that must be taken, namely carrying out academic coaching on the preparation of a syllabus that is integrated with cultural education and national character. The lack of provision for teachers in compiling a syllabus based on cultural education and national character needs to be addressed. Based on the results of observations in cycle I compared to the comparison in cycle II regarding the competence of compiling a syllabus based on cultural education and national character for teachers of SMP N 21 Semarang, there is a fairly good increase in competence even though the learning is carried out in PJJ. This can be seen from the recapitulation of observations in cycle II, there is an increase in competence, 10 teachers have been able to compile a syllabus based on cultural education and national character. However, there are still 2 teachers who have not been able to compile a syllabus. Thus, there are 83.3% of teachers who have been able to compile categories both syllabus based on cultural education and national character.The conclusion of this research is through academic supervision when PJJ can improve the competence of compiling a syllabus based on cultural education and national character.
在远程学习（PJJ）的情况下，在疫情期间，教师必须能够编制适当的学习大纲。PJJ期间需要一个基于文化和民族性格的教育大纲来专业地帮助学习过程。校长在进行学术监督以提高编制文化教育大纲和国民性的能力方面的作用是必要的。针对SMPN21三宝垄教师在PJJ期间所面临的问题，即在编制与文化教育和民族性格相结合的教学大纲方面能力低下，有必要找到解决方案。为了克服上述问题，校长们需要采取必须采取的行动，即就制定与文化教育和民族特征相结合的教学大纲进行学术指导。需要解决在编制基于文化教育和民族特征的教学大纲时缺乏教师的问题。根据第一周期的观察结果与第二周期的比较结果，即SMP N 21三宝垄教师编制基于文化教育和民族特征的教学大纲的能力，即使在PJJ进行学习，能力也有相当好的提高。这可以从第二周期的观察结果中看出，能力有所提高，10名教师能够根据文化教育和民族特征编制教学大纲。然而，仍有2名教师未能编制教学大纲。因此，83.3%的教师能够根据文化教育和民族性格编制教学大纲。本研究的结论是通过学术监督，PJJ可以提高基于文化教育和民族性格的教学大纲编制能力。

It is proven that students do not feel trained in operating the microscope and determine the magnification of the microscope, which means that the kinesthetic physical intelligence of students has not been trained. Based on these problems, a digital microscope is needed that can train students' kinesthetic physical intelligence in practicing plant anatomy. Digital microscope technology innovation is needed as a means of supporting plant anatomy practicum. In accordance with the nature of the research is the development of a digital microscope based on blended learning, the type used in this research is Research and Development (Research and Development). The trial subjects in this study were prospective biology education teacher candidates in the 2nd semester of Biology Education study program at the University of Wiralodra consisting of 5 classes and totaling 185 students. Sampling using cluster random sample method, consisting of 2 classes, namely Bio B (experimental class) and Bio D (control class) provided that the population is homogeneous. The results of the development of a digital microscope based on blended learning used in plant anatomy practicums were declared very valid. The blended learning digital microscope that was developed can improve the kinesthetic physical intelligence of students in plant anatomy practices, in the high category. There is a significant difference in the increase in kinesthetic physical intelligence of students between classes that use a digital microscope based on blended learning and classes that use a binocular light microscope.","PeriodicalId":46825,"journal":{"name":"Journal of Information Processing Systems","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2020-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42988440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The purpose of this study was to determine the effectiveness of open inquiry models on science process skills in ecosystem material at MAN 1 Indramayu. The type of research is quantitative research, the design that used in this study is Quasi Experimental that use parametric statistics. The population in this study was all students of class X MAN 1 Indramayu which amounted to 185 students. They were in both class X MIA 1 totaling 25 students and X MIA 2 totaling 20 students with cluster random sampling technique. The instruments that used were five item description questions. Based on the results of processing and data analysis of science process skills obtained the results of hypothesis testing as follows: thitung = 6.0215 and ttable = 1.671. Because tcount>ttabel, it could be conclude that Ho was rejected, meaning that the open inquiry model effective students' science process skills in the ecosystem material
本研究的目的是确定MAN 1 Indramayu生态系统材料科学过程技能的开放探究模型的有效性。研究类型是定量研究，本研究中使用的设计是使用参数统计的准实验。这项研究中的人群都是Indramayu X MAN 1班的学生，共有185名学生。采用整群随机抽样技术，他们分别在X MIA 1班共25名学生和X MIA 2班共20名学生中。使用的工具是五个项目描述问题。根据科学过程技能的处理和数据分析结果，得出假设检验结果如下：thitung=6.0215，ttable=1.671。由于tcount>ttabel，可以得出Ho被拒绝的结论，这意味着开放式探究模式有效地提高了学生在生态系统材料中的科学过程技能
