Analysis of the fabric of the concept for the formulation of activity, as well as analysis of the potential contribution of learning activities to increase the knowledge, skill and affection are
presented in a concept map. Evaluation and recommendation formulation of the material in the design of the material later identified thematic task assignments thematic material position
in the K 13 is presented in tabular form1. The identification of natural resources are exploited society and patterns of utilization management.
3. Result and Discussion 3.1. Research Result
This study presents the results of the shape-shape natural resource management in sub Manganitu who have dug concepts in physics and has made networking kosep. Management
of natural resources such community-based activities include:
3.1.1. Musical instrument Tagonggong 3.1.1.1. Description of The Tool
Tangonggong is a traditional music instrument typical of the islands Sagihe. This instrument existed before the Sangihe touched by religion. In this day and age tagonggong used in ritual
worship of the Creator called Genggona Langi. Until now, every time there Tulude ceremonies such as music tagonggong sasambo always shown side by side with the
accompanying dances.
3.1.1.2. Analysis of Physical Concepts Related to Musical Instruments Tagonggong
Scientific concepts contained in traditional music instrument tagonggong can be explained as follows:
a. When tagongong beaten or given an impulse force, it will cause a vibration on the
skin surface area of goat a change in the mechanical energy into energy vibrations that produce sound, vibration energy is then propagated by intermediaries medium
is air in the inner space tagonggong. The sound is heard depends on the distance between the sound source and the listener. The distance of sound waves per unit of
time is called the propagation of sound. Therefore, the sound is a wave, then the general form of mathematical basic
formula waves can be written: � =
�
= �. � 1
where: T = period of sound s,

= penjang sound waves m, v = velocity propagation of sound tagonggong
Sound wave propagation speed is affected by temperature and density. At the time the temperature of a substance increases, the molecules move faster so that the
frequency of collisions between the particles more. Sound Wave Energy. Propagation of sound waves in the carrying amount of energy
from one place to another. Energy transferred as vibration energy propagation medium between the particles. Energy which each particle is
W = � � . �. � � �
Wave power. Power is the energy that is propagated every second. � = � � . � � �

P = average power dirambatkan W, v = wave propagation speed m s,
f = frequency Hz A = amplitude m,
= mass medium through which long union b.
Intensity sound waves. The intensity of the sound wave is defined as the energy that is transferred per unit area per unit time or power per unit area perpendicular to the
direction of wave propagation speed.
c. Pipe resonance Organa Open. Resonance is the sound event come bergetarnya an
object because it has the same frequency as the source of the sound. d.
Tagonggong sound color is determined by the way the cross-section vibrations goatskin after given impulse
e. On the human auditory system. The human ear can be divided into three sections,
namely the outer, middle, and inner. f.
