Judul: Production and Quality of FH Dairy Cow Milk in Second Lactation Periods Given Depolarizing Katuk Supplementary Feed
Abstrak: Peningkatan produksi susu sapi FH dapat dilakukan dengan meningkatkan kualitas pakan, salah satunya dengan pemberian suplemen pakan. Penelitian bertujuan menganalisis pengaruh tambahan pakan daun katuk depolarisasi terhadap konsumsi pakan, produksi susu, dan kualitas susu pada sapi FH periode laktasi kedua. Penelitian ini menggunakan tiga ekor sapi FH dengan periode laktasi kedua yang dibagi menjadi tiga perlakuan yaitu perlakuan kontrol (P0) diberi pakan komplit GGL, perlakuan satu (P1) diberi pakan komplit GGL yang ditambahkan 100 g/ekor/hari bubuk katuk depolarisasi, dan perlakuan dua (P2) diberi pakan komplit GGL yang ditambahkan 100 g/ekor/hari pelet katuk depolarisasi. Peubah yang diamati adalah Temperature Humidity Index (THI), konsumsi pakan, produksi susu, dan kualitas susu. Hasil penelitian menunjukkan pemberian katuk depolarisasi bentuk bubuk dan memiliki rataan konsumsi pakan yang lebih rendah dibandingkan kontrol, nilai rataan konsumsi BK pakan yang relatif sama. Perlakuan katuk depolarisasi berpotensi meningkatkan produksi susu sapi FH laktasi kedua dengan kualitas susu yang relatif lebih tinggi pada bahan kering susu, bahan kering tanpa lemak dan kadar protein., Increasing milk production of FH cows can be done by improving feed quality, one of which is by providing feed additives. This study aims to determine the effect of additional depolarizing katuk leaf feed on feed consumption, milk production and milk quality in FH cows during the second lactation period. The cows used in this study amounted to three FH cows with the second lactation period which was divided into three treatments, namely control treatment (P0) given GGL complete feed, treatment one (P1) given GGL complete feed added 100 g / head / day depolarizing cotton powder, and treatment two (P2) given GGL complete feed added 100 g / head / day depolarizing katuk pelets. The observed modifiers were THI (Temperature Humidity Index), feed consumption, milk production and milk quality. The results showed that giving depolarizing katuk in powder and pelet forms can increase the consumption of BK feed. Depolarization katuk has to increase milk production of second lactation FH cows with relatively higher milk quality in milk dry matter, lean dry matter and protein content.

Judul: Produksi dan Kualitas Susu Sapi FH Periode Laktasi Ketiga dengan  Aditif Pakan Katuk Depolarisasi
Abstrak: Penelitian ini bertujuan menganalisis pengaruh suplementasi katuk depolarisasi terhadap produksi dan kualitas susu sapi FH periode laktasi ketiga. Penelitian ini menggunakan 3 ekor sapi FH periode laktasi ketiga pada satu bulan setelah beranak yang berumur 48 bulan yang dipelihara di PT.GGL di Lampung. Perlakuan menggunakan aditif pakan berupa bubuk dan pellet katuk depolarisasi selama 6 minggu (2 minggu sebelum beranak hingga 4 minggu setelah beranak). Data hasil penelitian dianalisis secara deskriptif. Peubah yang diamati terdiri dari konsumsi pakan, produksi dan kualitas susu. Kualitas susu meliputi berat jenis, kadar lemak, kadar protein, bahan kering (BK), dan bahan kering tanpa lemak (BKTL). Penggunaan katuk depolarisasi sebagai aditif pakan berpotensi meningkatkan produksi susu. Katuk depolarisasi menghasilkan susu dengan kadar protein, BK, BKTL yang relatif lebih tinggi, dan kadar lemak yang relatif lebih rendah dibandingkan kontrol., This study was conducted to determine the effect of supplementation depolarization katuk on production and milk quality of FH dairy cow in third lactation periods. FH dairy cow was used in study including three FH dairy cow on third lactation periods of one month after calving birth at the age of 48 months were kept in PT. GGL in Lampung. The feeding treatments was used feed additive of powder and pellet of depolarization katuk for 6 weeks (2 weeks before it calved and 4 weeks after it calved). The data are being analyzed with description. Variable measured including milk production and its quality. Milk quality included milk density, fat, protein, total solid (TS), and solid non-fat (SNF). Using depolarization katuk as feed additive potentially increase milk production. Depolarization katuk produced milk with protein, TS, SNF relatively higher, and fat relatively lower than control.

Judul: Penerapan Algoritme Genetika dalam Sistem Permainan Tebak Angka
Abstrak: The number guessing game is a modified game of mastermind created by Mordecai Meirowitz in 1970. The goal of the game is to guess a hidden sequence of numbers stored by others (human or computer) based on values obtained at each guess iteration. In this study, the game is applied into the system by using genetic algorithms, a method that has been successfully utilized to implement the mastermind game on the computer and get an effective solution for the game. Genetic algorithms work through a process of natural selection or commonly known as the evolutionary process, which will continue running until the system finds the optimal 4-digit series of numbers. The system is designed in order to guess those hidden numbers with minimal iterations using c++ programming language. The output of the program shows that the performance is determined by the first guess iteration.
