Judul: Rancang Bangun Alat Pengukur Suhu dan Salinitas Digital Berbasis Mikrokontroler 89C51.
Abstrak: Suhu dan salinitas memiliki peranan penting dalam dunia perikanan, terutama dibidang oseanograti, dimana parameter ini merupakan parameter dasar yang harus diambil dalam proses penelitian di bidang kelautan. Sangat minimnya produksi dalam bidang pengembangan instrumentasi pengukur parameter oseanografi, mengakibatkan nilai beli dari alat ini lumayan tinggi karena harus mendatangkan dari luar negeri (import). Pada penelitian ini digunakan suatu sistem single chip microcomputer, biasa ,dikenal sebagai mikrokontroler sebagai pemroses data sekaligus digunakan dalam proses kalibrasi.

Judul: Rancang bangun prototip alat pengukur intensitas cahaya dan suhu digital berbasis mikrokontroler
Abstrak: Suhu dan kecerahan memiliki peranan penting dalani dunia perikanan, han~pir semua metabolisme biota perairan diatur oleh suhu, sementara kecerahan berperan penting dalam menentukan tingkat penetrasi cahaya untuk keperluan fotosintesis dalan air. Penelitian ini mencoba merancang dan membangun sebuah instrumen yang dapat mengukur besaran intensitas cahaya (lux) yang dilengkapi dengan filter RGB (\Red.. Gre en. Blue) dan suhu dalam besaran Celcius. Pembuatan hardware dan software (perangkat keras dan lunak) instrumen ini berbasis pada penggunaan sahs chip tunggal sebagai pengolah data (sinyal) yang biasa disebut mikrokontroler.

Judul: Morphofunctional Characteristic of the Shoulder and Upper Arm Muscles of The Bornean Orangutan (Pongo pygmaeus)
Abstrak: Orangutans are arboreal primates that have similarities to gorillas and chimpanzees from both anatomical and physiological aspects, although there are distinct behaviors that allow for differentiation in the structure of the locomotor apparatus. This research aims to study the anatomy of the muscles of the shoulders and upper-arm of the Bornean orangutan associated with the type of locomotion and daily behavior. This study was conducted by observing the morphology of the shoulders and upper-arms muscles and watching their behaviors through video observations. The results showed that the rotator cuff muscles in orangutans were relatively thick resulted in well-fixed shoulders. Musculus rhomboideus occipitalis is only observed in orangutans to facilitate them during arboreal activities such as brachiation. The external trunk muscle in orangutans is found to be relatively large compared to chimpanzees and gorillas, due to the lifting of the upper arms while in trees and on the ground. Musculus brachioradialis and musculus biceps brachii were well developed as flexors of the elbow joint and hold the body mass while climbing up the tree. The Bornean orangutans' activities are more arboreal than those in gorillas and chimpanzees, thus their shoulder and upper arm muscles were more developed to support brachiation activities., Orangutans are arboreal primates that have similarities to gorillas and chimpanzees from both anatomical and physiological aspects, although there are distinct behaviors that allow for differentiation in the structure of the locomotor apparatus.
