. Aluminum is widely used as a roof, but it causes the room temperature to become hot due to its high thermal conductivity. This study aims to analyze the effect of styrofoam as a heat sink on the roof to room temperature. The research method is an experiment with variations in the thickness of styrofoam 1.5 cm and 3.0 cm. The shape of the roof is half- gable and oriented towards the north. The results showed that the average temperature of the top of the roof of the three miniature houses was much higher than the temperature of the bottom of the roof and higher than the room temperature. For the room temperature between the three miniature houses with different treatments, the order of the highest room temperature to the lowest room temperature is the miniature house without using styrofoam, using 1.5 cm styrofoam, and with 3 cm styrofoam. It can be seen that the use of styrofoam affects the room temperature and is effective in reducing the room temperature. In addition, the thicker the styrofoam used, the more heat is dissipated.
. 铝被广泛用作屋顶,但由于其高导热性,导致室温变热。本研究旨在分析聚苯乙烯泡沫塑料作为屋顶散热器对室温的影响。研究方法为泡沫塑料厚度1.5 cm和3.0 cm变化的实验。屋顶的形状是半山墙,朝向北方。结果表明:3个微型住宅屋顶顶部的平均温度远高于屋顶底部的温度,且高于室内温度;对于三种不同处理方式的微型房屋的室温,室温最高到室温最低的顺序为不使用泡沫塑料的微型房屋、使用1.5 cm泡沫塑料的微型房屋、使用3 cm泡沫塑料的微型房屋。可见聚苯乙烯泡沫塑料的使用对室温有影响,对降低室温是有效的。此外,使用的聚苯乙烯泡沫越厚,散发的热量就越多。

Abstrak. Gelombang cahaya yang mengalami pelenturan ketika melewati sebuah celah sempit disebut dengan fenomena difraksi. Fenomena difraksi dapat dilihat dengan melakukan eksperimen sederhana menggunakan bahan alam. Penelitian ini menggunakan kisi berbahan daun sereh ( Cymbopogon citratus ) dan tanaman lidah mertua ( Sansevieria trifasciata ) dengan menggunakan laser merah (λ = 632,8 nm) dengan beberapa variasi jarak kisi terhadap layar. Pola difraksi dianalisis menggunakan perangkat lunak Tracker. Hasil penelitian ini menunjukkan bahwa kisi difraksi menggunakan daun sereh dan lidah mertua menunjukkan fenomena difraksi cahaya sehingga dapat digunakan sebagai kisi difraksi sederhana berbahan alam dengan nilai d =(34.20 +/- 7.86) x 10^-6 m dan d =(62.50 +/- 13.60) x 10^-6 m pada kisi difraksi tanaman lidah mertua. Abstract. The light waves which flex when they pass through a narrow gap are called diffraction. The diffraction phenomenon can be seen by conducting simple experiments using natural materials. This study used a diffraction grating made from lemongrass leaves ( Cymbopogon citratus ) and sansevieria ( Sansevieria trifasciata ) using a red laser (λ = 632.8 nm) with several variations in the distance of the diffraction grating to the screen. The diffraction patterns were analyzed using Tracker software. The results of this study show that the diffraction grating using lemongrass leaves and sansevieria  show the phenomenon of light diffraction so that it can be used as a simple diffraction grating made from natural ingredients with values d =(34.20 +/- 7.86) x 10^-6 m of lemongrass leaves and d =(62.50 +/- 13.60) x 10^-6 m for the diffraction grating of the sansevieria.
摘要光波通过一个狭窄的缝隙碰撞,称为衍射现象。分形现象可以通过使用天然材料进行简单的实验来观察。这项研究使用了不同层次的绿叶(Cymbopogon citratus)和海洋植物(Sansevieria trifasciata),使用了红色激光(λ=632.8nm),屏幕上的层距离有所变化。使用软跟踪器设备分析分数模式。研究结果表明,使用绿叶和海洋语言的衍射层表现出光衍射现象,因此它可以用作海洋语言衍射表面的d=(34.20+/-7.86)x10^-6m和d=(62.50+/-13.60)x10^-6 m的自然衍射层。摘要当光波穿过狭窄的缝隙时会发生弯曲,这种现象被称为衍射。衍射现象可以通过使用天然材料进行简单的实验来观察。本研究使用了由柠檬草叶(Cymbopogon citratus)和三叶草(sansevieria trifasciata)制成的衍射光栅,使用红色激光(λ=632.8nm),衍射光栅到屏幕的距离有几个变化。使用Tracker软件分析衍射图案。本研究的结果表明,使用柠檬草叶和三叶草[UNK]的衍射光栅显示出光衍射现象,因此它可以用作由天然成分制成的简单衍射光栅,其值为:柠檬草叶d=(34.20+/-7.86)x10^-6m,三叶草衍射光栅d=(62.50+/-13.60)x10^-6[UNK]m。

. This study aims to determine the feasibility and response of a limited trial of capacitor practicum guides based on Science Process Skills (SPS) as a physics learning tool. The method used is research and development (R&D) with the 4-D model. This practicum guide as a physics learning tool can facilitate several practicum activities in which each step is related to SPS, including the practicum capacitance of parallel pieces of capacitors, an arrangement of capacitors (series-parallel-combined), and charging-discharging of capacitors. The results showed that the practicum guide was feasible, namely with a feasibility value of 81.235%, which was categorized as very feasible and obtained student responses in the very good category of 85.2%. Based on the results obtained, the Capacitor Practicum Guide can facilitate students’ SPS and is suitable for use as a tool for learning physics.
