Judul: Analysis of Provision and Commercialisation Perception of Fibre Feed in Rural Dairy Farms in Lembang - West Bandung District
Abstrak: Penelitian ini bertujuan untuk mengetahui sumber pakan serat yang biasanya digunakan, menganalisis kegiatan penyediaan pakan serat di peternakan sapi perah Lembang pada musim kemarau, mengetahui rantai pasok pakan serat, menganalisis nilai tambah usaha peternakan, mengetahui minat beli peternak terhadap pakan serat, serta mengetahui faktor peternak dan pilihan jenis pakan dalam pembelian pakan serat. Wawancara dilakukan kepada 50 peternak untuk memperoleh informasi pola penyediaan, rantai pasok pakan serat, dan nilai tambah usaha peternakan. Metode survei secara purposive digunakan dalam mengetahui persepsi peternak terhadap komersialisasi pakan serat dengan responden sebanyak 100 peternak. Pengambilan sampel berupa pakan serat yang digunakan di peternakan tersebut menggunakan teknik pengambilan acak sederhana. Data yang diperoleh dianalisis secara deskriptif. Pakan serat yang diberikan kepada sapi perah berupa rumput budi daya, tumbuhan alam, legum, dan limbah tanaman yang seluruhnya berasal dari daerah sekitar (≤ 30 km) dengan kandungan nutrien yang bervariasi. Terdapat 16 pola penyediaan pakan serat pada musim kemarau dengan pola terbanyak yaitu kombinasi mengarit di lahan sendiri dan membeli. Berdasarkan perhitungan RFV, legum dan limbah sayuran memiliki kualitas yang baik. Rantai pasok pakan serat relatif pendek (1–4 aktor) karena pakan serat yang digunakan umumnya dalam bentuk segar dan tanpa diolah. Rataan nilai tambah (Rp1324 kg-1) dan keuntungan usaha peternakan (Rp820.82 kg-1) memiliki nilai positif walaupun dengan pemberian pakan serat yang berbeda-beda. Sebagian besar peternak rakyat sapi perah di Kecamatan Lembang memiliki persepsi baik terhadap komersialisasi pakan serat (96%). Rumput gajah menjadi pilihan terbesar dalam pembelian pakan serat yang akan dibeli oleh peternak (62%). Kualitas merupakan faktor utama keputusan peternak dalam pembelian pakan tersebut (33%)., This study aims to explore and understand the source of fibre feed that is frequently utilised, analyse the activities of fibre feed provision in dairy farms during the dry season, investigate the fibre feed supply chain, analyse the valueadded characteristic of dairy farms, to understand the perceptions of dairy farmers in Lembang District regarding their interest in purchasing fibre feed, and to explore the choice of feed types as well as factors in determining the purchase of fibre feed by the farmers. The data was collected by adopting an interview method with 50 farmers to gather information regarding the provision pattern, supply chain of respective fibre feed, and value-added of dairy farms. The purposive sampling method was implemented in this study with a sample of 100 farmers to understand the perceptions of dairy farmers regarding fibre feed commercialisation. The fibre feed sample in the dairy farms was taken using a simple random sampling technique. The data acquired was analysed using descriptive analysis. The result implied that the fibre feed that had been given to the dairy cows was cultivated grass, natural grass, legumes, and plant residue that entirely supplied from neighbourhood area (≤ 30 km), which had different nutrient content. There were 16 provision patterns of fibre feed in the dry season, the vast majority of provision pattern was the combination of foraging from the farmer’s land and feed purchasing. By referring to the RFV calculations, legumes and vegetable waste have good quality. The fibre feed supply chain was relatively short, which was about (1–4

Judul: Beberapa faktor yang mempengaruhi produksi dan penawaran daging, susu, dan telur di Jawa Barat dan Lampung
Abstrak: This study was prepared due to the essential role of meat, milk, and egg as nutritions food to increase the standard of living. for these commodities. There was an increasing demand However there is a slow rate of increase, if not decrease, of the livestock population as the source of these commodities. The purpose of this study was to identify variables at the farmers level affecting the production and supply of meat, fresh milk, and fresh egg, in the light of the possibility of developing livestock production. The survey was conducted at the Province of West Java and Lampung, for the two regions reveal some differences with respect to the prospect of livestock development. By comparing these two regions, it is expected that the result will give some ideas in formulating live- stock development policy not only for the two regions, but also for other regions in Indonesia. Regression analysis of production and supply of meat does not tell us much, for the independent variables could a not explain the production and supply (R2 less than 0.20). Nevertheless, data indicated that on the average a Farmer owns only 2.7 buffaloes in west Java and 4.6 buffaloes and 2.7 cattle in Lampung. Only 17 percent of farmer In West Java sold any Of their cattle within the year proceding the data of enumeration and only 23 percent in Lampung (Table 4.14). Most of the sales are consumptive , (95 percent) such as for housing, education expenses, ritual ceremonies. From the supply point Of view, the amount and frequency OF sales were relatively smal1. Supply elasticity meat to price was 1.14566 for buffalo and 1.05049 for cattle. There was on indication that time variable has some influence On supply of meat. For instance, more cows and buffaloes are slaughtered in the month of lebaran and new year. Elasticity of milk supply to the amount of dairy cow was 0.645 to productivity 0.93892, and to ratio of milk price to dedak price 0.13874. Elasticity of ego Supply to the amount of layers was 1.06881 and to productivity of layers is 0.9643. was Judging from the results explained above, evident that the farmers have little variables selling their livestock. On the other hand due to the high elasticities at slaughtering agent, (pejagal), it could be concluded that butchers have a strong bargaining position in livestock marketing. dst. ...

Judul: Quantum Convolutional Neural Network (QCNN) for Classification Brain Tumor MRI Image
Abstrak: Penelitian ini bertujuan untuk mengembangkan model deteksi tumor otak menggunakan citra MRI dengan metode Quantum Convolutional Neural Network. Data yang digunakan adalah citra MRI otak yang terdiri dari citra tumor otak glioma, meningioma, hipofisis, dan negatif tumor yang dibagi kedalam data latih dan uji dengan rasio 80:20. Selanjutnya data latih dilakukan penyeimbangan dengan teknik oversampling. Dilakukan pengembangan model untuk mendeteksi tumor otak (biner), dan juga model untuk mengklasifikasikan jenis tumor otak (multiclass). Parameter yang digunakan dalam pengembangan model adalah jumlah ukuran filer = 2 dan kedalaman = 4, dengan qubit 4, dan dilatih dengan jumlah epoch sebanyak 10. Data akan diproses dengan metode Quantum Convolutional Neural Network yang terdiri dari lapisan quantum convolution, lapisan flatten, dan lapisan dense. Model multiclass mendapatkan akurasi 52%, setelah data latih diseimbangkan akurasi model meningkat menjadi 62%, sedangkan model biner mendapatkan akurasi 88%, setelah data latih diseimbangkan akurasi model meningkat menjadi 89%.
