However, its consumption in Indonesia remains relatively low. The continuous increase in beef prices has led to fraudulent practices, such as mixing fresh and non-fresh meat, which poses serious health risks due to the presence of harmful bacteria in spoiled meat. This research aims to classify the freshness level of beef using feature extraction techniques through the Gray Level Co-occurrence Matrix (GLCM) and the Random Forest Algorithm. The study uses 400 augmented image data, divided into 238 training data and 160 testing data with a 60:40 ratio. The results show that the Random Forest algorithm achieved an Accuracy of 93%, while the Decision Tree reached 88%.Keywords: Beef, Image Classification, Gray Level Co-occurrence Matrix (GLCM), Random Forest, Decision Tre
Adaptive Solar Panel in Wiyata Tech Village, Towards Energy Independence
Full text linkNighttime illumination in Wiyata Tech Village, Kutamanah, Sukasari District, Purwakarta, has been limited due to the reliance on low-capacity lamps.

Pengaruh Jenis Sambungan Jari dan Sambungan Miring pada Balok Laminasi Galar Bambu Petung Terhadap Keruntuhan Geser
Full text linkABSTRAKKebutuhan kayu sebagai bahan konstruksi yang semakin meningkat tidak seimbang dengan ketersediaan bahan baku kayu yang memadai, sehingga pemanfaatan bambu sebagai alternatif harus lebih dioptimalkan. Salah satu upaya untuk mengoptimalkan pemanfaatan bambu yaitu dengan teknik laminasi, sehingga dengan dapat diperoleh balok sesuai dengan dimensi yang diinginkan. Akan tetapi penggunaan sambungan sulit dihindarkan pada struktur bentang panjang sehingga diperlukan jenis sambungan yang paling optimum antara sambungan jari (finger joint) dengan sambungan miring (scarf joint). Bambu yang digunakan adalah bambu petung yang dibentuk galar. Benda uji terdiri 3 variasi meliputi balok tanpa sambungan dari bahan galar (BLP-G), balok dengan sambungan jari (BLP-GJ), serta balok dengan sambungan miring (BLP-GM). Aplikasi sambungan pada balok laminasi memberikan pengaruh terhadap penurunan kekuatan balok. Penurunan kekuatan balok masing-masing sebesar 17,863% untuk sambungan jari (BLP-GJ), 66,119% untuk sambungan miring (BLP-GM). Hasil penelitian memperlihatkan bahwa balok BLP-GJ memiliki kekuatan dalam memikul beban yang lebih tinggi dibandingkan balok BLP-GM. Hal ini disebabkan aplikasi sambungan jari memiliki sifat saling mengunci dibanding sambungan miring yang memiliki kekuatan pada bidang perekat dan kemiringan sambungan. Berdasarkan hasil penelitian dapat disimpulkan bahwa aplikasi sambungan jari lebih kuat dibanding sambungan miring untuk aplikasi sambungan pada balok laminasi.Kata kunci: balok laminasi bambu, finger joint, scarf joint ABSTRACKThe utilization of wood as a building material has indicated an increasing whether of structural and nonstructural elements. The necessity of wood could not be fulfilled due to the lack of wood with a large diameter. On the other hand, the utilization of bamboo has not been optimal so far because of its short durability of bamboo and the limited dimension of bamboo. The problem can be solved by laminating and joining. The research was conducted to optimize the joint type of finger joint and scarf joint. The bamboo used in this research was bamboo Petung (Dendrocalamus asper). Specimens of laminated beams were made in 3 variations. Beams were made without joint (BLP-G), beams with finger joint (BLP-GJ), and beams with scarf joint (BLP-GM). Each variation consists of 3 samples. Application joint at laminated beam influenced degradation of the strength of the laminated beam. The strength of beam degradation is 17,863 % (BLP-GJ), and 66,119 % (BLP-GM). The result of the experiment showed that BLP-GJ beams were stronger than BLP-GM beams because the application finger joint had better interlocking than the scarf joint. Based on the experimental result, it could be concluded that the application finger joint was stronger than the scarf joint.Keywords: bamboo laminated beam, finger joint, scarf join

KINERJA BLACK SOLDIER FLY LARVAES (BSFL), HERMETIA ILLUCENS L., DALAM PENGOLAHAN LUMPUR TINJA DENGAN PENCAMPURAN SAMPAH PERIKANAN DAN SAMPAH BUAH PIDADA
Full text linkSanitasi di Muara Gembong tergolong ‘belum layak’ karena toilet tidak terhubung dengan sistem pembuangan yang memadai, dan unit pengumpulan desentralisasi tidak sesuai standar nasional. Oleh karena itu, pengolahan lumpur tinja setempat dari sumbernya penting untuk meningkatkan akses sanitasi layak. Penggunaan Black Soldier Fly Larvaes (BSFL) untuk mengolah lumpur tinja merupakan pendekatan inovatif guna mengurangi volume lumpur tinja dan menghasilkan produk yang tinggi protein sebagai pakan ternak. Namun, lumpur tinja sebagai substrat BSFL tidak mendukung pertumbuhan optimal larva karena kandungan nutrisinya rendah. Untuk meningkatkan nutrisi, co-substrate berupa limbah perikanan (IKN) dan buah pidada (PDD) ditambahkan. Tujuh variasi substrat diformulasikan, dan sekitar 100 mg substrat/larva/hari diberikan selama 12 hari. Kinerja BSFL dipantau melalui survival rate (SR), waste reduction rate (WR), dan biomass conversion rate (BCR). Hasil menunjukkan penambahan IKN secara signifikan meningkatkan kinerja BSFL (P < 0,05), dengan substrat 50% lumpur tinja + 50% IKN memberikan nilai SR, WR, dan BCR tertinggi. Sebaliknya, penambahan PDD menurunkan SR dan WR, terutama pada varian 50% lumpur tinja + 50% PDD (F1-S1)
